ADVERTISEMENT. 


The extension of the scope of the National Museum during recent 
years and the activity of the collectors employed in its interest have 


caused a great increase in the amount of material in its possession. 


Many of the objects gathered are of a novel and important character, 
and serve to throw a new light upon the study of nature and of man. 

The importance to science of prompt publication of descriptions of 
this material led to the establishment, in 1878, of the present series 
of publications, entitled ‘* Proceedings of the United States National 
Museum,” the distinguishing peculiarity of which is that the articles 
are published in pamphlet form as fast as completed and in advance of 
the bound volume. The present volume constitutes the twenty-second 


of the series. 


The articles in this series consist: First, of papers prepared by the 


“scientific corps of the National Museum; secondly, of papers by others, 


founded upon the collections in the National Museum; and, finally, 
of facts and memoranda from the correspondence of the Smithsonian 
Institution. 

The Bulletin of the National Museum, the publication of which was 
commenced in 1875, consists of elaborate papers based upon the col- 
lections of the Museum, reports of expeditions, ete., while the Pro- 
ceedings facilitate the prompt publication of freshly acquired facts 
relating to biology, anthropology, and geology, descriptions of restricted 
groups of animals and plants, the discussion of particular questions 
relative to the synonomy of species, and the diaries of minor expe- 
ditions. . 

Other papers of more general popular interest are printed in the 
Appendix to the Annual Report. 

Papers intended for publication in the Proceedings and Bulletin of 
the National Museum are referred to the Advisory Committee on Pub- 


lications, composed as follows: Frederick W. True (chairman), Marcus 
“Benjamin (editor), James KE. Benedict, Otis T. Mason, Leonhard 
‘Stejneger, and Lester F. Ward.

THE OSTEOLOGICAL CHARACTERS OF THE FISHES OF 
THE SUBORDER PERCESOCES. 


By EDWIN CHAPIN STARKS, 


Assistant Professor in the Department of Biology and Curator of the Museum, University 
of Washington, Seattle, Washington. 


A study of the skeletons of several representatives of the families 
Atherinide, Mugilide, and Sphyrenidie, which are grouped together 
under the suborder Percesoces, reveals the fact that they are not so 
closely allied to each other as their external similarity would lead one 
to suppose. 

The specimens from which my observations were made are adult 
examples of Atherinopsis califormensis, Menidia notata, Mugil cephalus, 
and Sphyrena argentea. 

In examining the crania of these species attention is attracted at 
once to the fact that in all of them the epiotics are developed into long, 
thin processes which divide into more or less bristlelike filaments. 

There is little else in purely internal characters whereby to differen- 
tiate these families as a group from other Acanthopteri. In order to 
So differentiate them we must turn to the well-known external charac- 
ters—a spinous dorsal in conjunction with the abdominal ventral fins, 
high pectoral fins, and unarmed opercles. 

If, however, we eliminate the Sphyrenide (which, on account of its 
fanglike teeth, set in deep sockets, its separate superior pharyngeals 
of third and fourth branchial arches, its lack of parapophyses on ante- 
rior vertebrae, and other characters, we may well be justified in doing) 
and place it in a separate superfamily coordinate with that in which 
we place the Mugilide and Atherinids, we shall then have remaining 
a more compact group, notwithstanding the great difference in number 
of vertebre in the two tamilies of which it is composed. 

In it we find the parapophyses developed on all the abdominal ver- 
tebre, the anterior neural spines flattened, wide and thin, the supra- 
clavicle very small, the superior pharyngeals of each side of the third 
and fourth branchial arches anchylosed, and the teeth small, not fang- 
like and set in sockets.

DIAGNOSIS OF THE SUBORDER PERCESOCES. 


& 


Two dorsal fins, the first spinous and more or less remote from the 


second; ventral fins abdominal, with 1 spine and 5 rays; third and 


fourth superior pharyngeals of each side separate or anchylosed; lower — 


pharyngeals separate; pectorals elevated, nearly on a level with upper 
part of clavicle; epiotics of adult produced backward and more or 
less divided into bristlelike filaments; myodome present, opened or 
closed posteriorly; opercles unarmed; parietals separated by supra- 
occipital; supraoccipital crest developed posteriorly, not extending 
above level of balance of cranium; postclavicle of superior and inferior 
parts; anterior interhemal not differentiated; epipleurals present; 
coronoid bone present;' suborbital ring without suborbital shelf. 


DIAGNOSIS OF THE SUPERFAMILY ATHERINOIDEA. 


Cleft of mouth not wide; teeth, when present, small, not set in sock- 
ets; maxillary without supplemental bone; third and fourth superior 
pharyngeals of each side anchylosed; supraclavicle reduced in size; 
lower limb of posttemporal attached to opisthotic by ligament or suture;

ing; ethmoid normal, not overlying prefrontals and vomer or extend- 
ing to lateral edge of rostrum; anterior neural spines laterally tlattened ; 
parapophyses developed on all abdominal vertebre. 


DIAGNOSIS OF THE FAMILY ATHERINIDA. 


Lower limb of post-temporal attached to opisthotic by ligament; 
basisphenoid developed; myodome opening to exterior posteriorly;

typical in shape, bearing teeth; vertebree numerous, from 45 to 52; 
first dorsal with from 3 to 8 spines; anal with 1 spine. 


DIAGNOSIS OF THE FAMILY MUGILIDZ. 


Lower limb of post-temporal attached to cranium by dentate suture; 
basisphenoid absent; myodome not opening to exterior posteriorly; 
foramen magnum region produced; superior pharyngeals of complex 
shape, not bearing teeth; vertebre few in number, about 24; first 
dorsal with about 4 spines; anal with 2 or 3 spines. 


‘This character seems to have been made too much of by the systematists and not 
enough of by the anatomists. Whether it is homologous with the coronoid as it 
occurs in some reptiles, or is one of the osteological peculiarities common to fishes, 
or whether it is developed with age, being the ossified end of the ligament that is 
attached to it, I will not attempt to say with the material at hand. The last sup- 
position seems to be the least tenable, since the ossification is not a gradual transi- 
tion from cartilage to bone, as we would expect in that case, but takes the form of a 
distinct bone larger than the end of the ligament. I find it present in nearly every 
species examined (my material being adult examples), among them the following 
miscellaneous genera: Amiurus, Cyprinus, Lucius, Alosa, Holocentrus, Pomoxys, Lobotes, 
Roccus, Caranx, Archosargus, Neomeanis, Tautoga, Pomatomus, Rachycentron, Scorpe- 
nichthys, Lopholatilus, Melanogrammus, and Gadus.

Vertebre, in number, with hypural, 52. In another specimen, 50. 
Impossible to draw a line between abdominal and caudal vertebre. 
Twenty-fifth and succeeding posterior vertebrie with an arch between 
each pair of parapophyses, behind which parapophyses gradually 
become longer, thinner, and wider, till at the thirty-fourth their tips 
approach each other and touch, forming a gradually decreasing tunnel 
continued to the forty-first, where it becomes obsolete. This tunnel 
is probably for reception of posterior end of air bladder. Only those 
vertebre from the forty-first backward have typical hzmal spines. 

Anterior neural spines, flattened into thin plates, much as in Mugil.

reach to a level with lower end of posttemporal. 

Clavicle with a downward-hooked process on inner anterior edge. 

Hypercoracoid placed high on clavicle. Its foramen, though wholly 
contained within hypercoracoid, is so near its forward edge that it 
deeply notches edge of overlying clavicle. 

Hypocoracoid falciform, Its inner upper corner but slightly touch- 
ing clavicle, thence curving quickly away and only weakly attaching 
to it at its long lower end.

superior pharyngeal is attached. 

Superior! to all else is a large pharyngobranchial of very complex 
shape. Itis attached to and above the last three epibranchials and 
even to and above pharyngobranchial of second arch. It is doubtless 
the anchylosed pharyngobranchials of third and fourth arches. Tor 
ease of describing, it may be said to consist of a superior and an 
inferior part. The inferior, to which the epibranchials are attached, 
runs straight back to last arch. Springing from its anterior end a thin, 
imperforate, saucer-shaped superior bone arches widely over it, project- 
ing both laterally and posteriorly. This upper part is further supported

number 24. 

First five vertebre with neural spines flattened laterally and forming 
a more or less continuous crest. 

Parapophyses very large; wide and thin at the edges. Developed 
on all abdominal vertebrae, growing gradually larger and more nearly 
horizontal anteriorly, until the third is reached, thence scarcely dimin- 
ishing in size to the atlas. : 

A process developed from each anterior zygapophysis, which is anky- 
losed with its fellow of the opposite side, forming an arch over neural 
cord, and extending obliquely forward to neural spine. 

A spine developed from each posterior zygapophysis pointing 
obliquely backward and overlapping outer edge of that from anterior 
zy gapophysis. 


1The arches described as straightened out for examination, not as in natural posi- 
tion with the supericr pharyngeals turned downward.

Inferior zygapophyses developed as large spines, each anterior spine 
the longer and pointing obliquely forward; each posterior pointing 
obliquely backward at right angles, meeting it at its middle. 

Hypural assisted in supporting caudal fin by spines of two preceding 
vertebre and two auxiliary spines substituting neural spine of first 
preceding vertebra.

NOTES ON BIRDS FROM THE CAMEROONS DISTRICT, 
WEST AFRICA. 


By Harry C. OBERHOLSER, 
Assistant Biologist, Department of Agriculture. 


The U.S. National Museum has recently acquired a small collection 
of birds made by Mr. G. L. Bates in the Cameroons District of West 
Africa. At the request of the curator of the Division of Birds the 
writer has prepared the following report upon this collection which, 
though it contains no novelties, comprises several species of consider- 
able interest; and the data from the labels has been supplemented by 
such critical remarks upon the specimens as the circumstances appear 
to make desirable, including the creation of a new genus for the recep- 
tion of the species commonly known as Andropadus virens. 

The 59 specimens are referable to 32 species, and are nearly all from 
Efulen—or Ebfulla, as it is called on German maps—in the Njondo 
River region, about 100 miles inland. Only two specimens, one each 
of Ceratogymna atrata and Actitis hypoleuca, are from elsewhere, they 
coming from Batanga on the coast. The dates of collecting range 
from May 30 to August 3, but a large proportion of the specimens were 
taken in June.

One adult male. Although Dr. Reichenow does not include’ this 
form among the birds of the Cameroons District, there seems to be little 
doubt of the correct identification of the present specimen, as it agrees 
perfectly with the plate and description given by Dr. Sharpe.’ The 
present locality must be quite or at least very near the northern limit 
of the range of malimbicus, which probably passes thence into Halcyon 
malimbicus forbesi, the latter occupying the region from at least the 
Cameroons Mountains northward to Sierra Leone, and in turn replaced 
in Senegambia by Haicyon malimbicus torquatus.

Two specimens, one of which, though nearly adult, still retains some 
indications of immature plumage. The maxilla is red, save for a dusky 
spot on each side at the base and a narrow blackish line along the 
apical two-thirds of the culmen. The flanks are distinctly barred with 
dusky; the sides of the head, including the superciliary region, together 
with the nape and occiput, have a conspicuous wash of bluish, and the 
whole upper surface, particularly the anterior portion, is darker and 
duller than in the fully adult.

GYMNOBUCCO CALVUS (Lafresnaye). 


Bueco calvus LAFRESNAYE, Rev. Zool., 1841, p. 241. 
Gymnobucco calvus BONAPARTE, Consp. Avium, I, 1850, p. 141. 

Two specimens, male and female, June 11, 1895. Both of these indi- 
viduals are typical of the so-called Gymnobucco peli, and are undoubt- 
edly adults. From examination of these and from comparison with an 
adult specimen of true G. calvus from Fantee, the writer is very strongly 
inclined to consider Dr. Sharpe correct in his opinion of the specific 
distinctness of G. peli. That they are sexes of the same species seems 
unlikely if any reliance is to be placed upon the sexing of collectors. 
The examples at hand indicate that calvus is in all its dimensions a 
decidedly larger bird than peli, this difference of dimensions conspicu- 
ous in the bill. It lacks entirely the tufts of nasal bristles so conspicu- 
ous in peli, and the scattered bristles on the top of the head are much 
fewer in number. The number of specimens at present available is too 
limited, however, to warrant a definite opinion, and final disposition of 
the question must necessarily be deferred until a sufficient series prop- 
erly sexed can be brought together.

An adult female of this little known but very distinct species is con- 
tained in the present collection. As no detailed description of the 
species appears to have been published, the following, taken from this 
example, is added: 


Top of head black, thickly spotted with greenish yellow; remainder of upper 
parts, including wings and tail, sepia brown; the back -and wing-coverts with 
roundish markings of greenish yellow; wing-quills (excepting outer primaries), tail- 
feathers, and upper tail-coverts margined externally with greenish yellow, this most 
golden on the wings, most greenish on the tail-coverts; sides of head black mottled 
with white; throat white, the feathers with shaft markings of brownish black; 
rest of lower parts dull yellowish green, the feathers of the jugulum with narrow 
black shaft lines and hair-like tips; the breast and abdomen with roundish spots of 
dark brown, these expanding into bars posteriorly.

One specimen of this rare species is contained in the collection. 
Although sexed as a female, the yellow feathers on the occiput seem to 
indicate its being a male. Otherwise it is apparently typical, though 
its measurements are rather small.

DENDROMUS PERMISTUS (Reichenow). 


Picus (Campothera) permistus REICHENOW, Journ. fiir Orn., 1876, p. 97. 
Campethera permista SHARPE and BUVIER, Bull. Soc. Zool. France, 1876, p. 312. 

The single example is an adult male. It differs from an Angola 
female in the U. 8S. National Museum by reason of its brighter green 
upper surface and deeper color below—the latter particularly noticeable 
posteriorly—and by its somewhat smaller size. Should a satisfactory 
series prove these differences to be sufficiently constant, the Cameroons 
form, provisionally established on smaller .size by Dr. Sjostedt,' must 
be known as Dendromus permistus pumilus. 

The generic term Dendromus Swainson, 1837, pmirad nies by several 
years Campethera Gray, 1841, and should be used for the group which 
in current usage passes under the name Campothera. There is no more 
reason for rejecting Dendromus on the ground of a former Dendromys? 
than there would be to refuse Pica on account of a previous Prcus, for 
Dendromus is derived from dévdpov and Spopos, while Dendromys 
comes from dévdpor and js, the terminal elements involving more 
than mere grammatical endings, although as latinized they differ only 
in a single letter.

Apaloderma narina SWAINSON, Classif. Birds, II, 1837, p. 337. 

The single specimen is an immature male, and differs from all the 
other examples of this form with which it has been compared in the 
color of the upper surface, which is clear grass-green, with scarcely a 
trace of the bronzy tinge so evident in ordinary specimens. Otherwise 
it is apparently typical, the wing-coverts being broadly edged with 
green, thus showing no approach to constantia.

placed in the genus Criniger, and by Captain Shelley® in Pyrrhurus, 

but in pattern of coloration, as well as in structural characters, it is so

5 Brachypodide is certainly untenable as a family name for this group if the genus 
Brachypodius, upon which it is founded, be considered a synonym of Microtarsus. 
Even if Brachypodius is distinct, the proper designation for the family is apparently 
Pycnonotide, since it seems to have been the name first used.

per fect | a miniature of Xenocichla (= Bleda) syndactyla that Cassin 
apparently was quite right in calling it a Xenocichla (— Bleda). With 
regard to the specific name, however, it seems to the present writer 
unnecessary to reject icterina of Bonaparte for tricolor of Cassin solely 
on account of a previous icterica in the same genus; for the two names 
are sufficiently distinct, both actually and etymologically, not to cause 
any serious confusion. 


EURILLAS,! new genus. 


Chars. gen.— Genus generi “Andropadus” dicto simile, a quo differt 
rostro latiore et depressiore, naribus rotundatis. 
Type.—Andropadus virens Cassin. 

The type of the genus Andropadus is A. importunus (Vieillot), from 
which A. virens differs so much in structural characters that its generic 
separation seems necessary. The very much broader, more depressed 
bill, oval instead of slit-like nostrils, are very distinctive. The tomia 
are scarcely or not at all incurved, and the closed bill is thus without the 
groove which is so conspicuous along the commissure of Andropadus 
importunus. The outline of the culmen is nearly straight until near the 
tip, while in Andropadus it is curved almost from the base. The rictal 
bristles are also more strongly developed in Eurillas. From other 
related genera, except Stelgidillas,’ Eurillas may easily be distinguished 
by the serrations of the subterminal portion of the cutting edge of the 
maxilla, and from Stelgidillas by the short, broad, and much-depressed 
bill. 

Of the other species commonly referred to Andropadus, only latiros- 
tris has been examined, so that with this exception it has not been pos- 
sible to determine where they should be placed. 


EURILLAS VIRENS (Cassin). 
Andropadus virens CASSIN, Proc. Acad. Nat. Sci. Phila., 1857, p. 34. 


Two specimens. Although both are apparently adults, one is much 
more brownish both above and below. 


EURILLAS LATIROSTRIS (Strickland). 
Andropadus latirostris STRICKLAND, Proc. Zool. Soc., 1844, p. 100. 

One specimen. There may be some doubt about the advisability of 
referring this species to Hurillas, for in some characters it is aberrant; 
but it certainly is not an Andropadus, and, unless a separate genus be 
created for its reception, is apparently best placed as above. 


PYCNONOTUS BARBATUS GABONENSIS (Sharpe). 
Pycnonotus gabonensis SHARPE, Proc. Zool. Soc., 1871, p. 132, pl. vu, fig. 1. 
Three specimens, practically identical in plumage, except that one 
has almost no tinge of yellow on the crissum. The much darker shade 
of all brown portions of the plumage easily distinguishes this form from

true barbatus ; but intermediate specimens, from the region of the river 
Niger,' make necessary its reduction to subspecific rank. An example 
in the U. S. National Museum collection, from Fantee, is intermediate, 
but apparently nearer gabonensis.

Two specimens. Both are sexed as males, but one is noticeably paler 
both above and below, having also much less rusty on the superior 
wing-coverts, is slightly smaller, and may possibly be a female.

Muscicapa viridis MULLER, Syst. Nat., Anhang, 1776, p. 171. 
Muscicapa cristata GMELIN, Syst. Nat., I, 1788, p. 938. 

One specimen of this puzzling species is in the collection. The head 
is metallic greenish blue, as is also the throat, which shades off gradu- 
ally into the bluish slate of the abdomen and crissum; the back and 
well-developed tail are rufous. . 

This is the species commonly called Terpsiphone cristata, but Miiller’s 
name viridis has twelve years’ priority, and should not be ignored. 


ARTOMYIAS FULIGINOSA J. and EK. Verreaux. 


Artomyias fuliginosa J. and FE. VERREAUX, Journ. f. Orn., March, 1855, p. 104.

marked female.

Platysteira castanea FRASER, Proc. Zool. Soc., 1842, p. 141. 
Diaphorophyia castanea SHARPE, Ibis, 1873, p. 172. ; 

Three specimens. Two are adult males in breeding plumage; the 
other is apparently a young female. It differs from the adult female in 
being rather darker above, the head dull grayish brown instead of 
bluish gray; the burnt-sienna brown of throat and jugulum much 
mixed with whitish.

One specimen, apparently an adult female, taken June 15, 1895. 
This rare sunbird does not seem ever to have been recorded north of — 
Gaboon, and thus is a very interesting addition, to the fauna of the 
Cameroons District.

In the series of seven specimens there is comparatively little indi- 
vidual color difference. ‘The upper parts in some are rather more tinged 
with brownish; the under surface varies somewhat in the extent and 
shade of the greenish wash; but otherwise they are alike. There is, 
however, a considerable variation in measurements. A specimen in 
the U.S. Museum collection, from Fantee, is noticeably more brownish 
both above and below, and suggests the possibility of the existence of 
a northern race.

The single specimen is an adult male in perfect plumage. It is

with this does not exhibit the restriction of black on the forehead which 
is stated by Dr. Sharpe to characterize the Camerocns birds.

Two specimens, June 26, 1895,in immature plumage. As this con- 
dition differs somewhat from that of the adult, and appears to be 
unknown, the following description is offered: Above, including wing- 
coverts, light chocolate brown, duller and rather darker on the head, 
but without conspicuous contrast; upper tail-coverts dull red; wing: 
quills fuscous, narrowly margined with paler; tail sepia, the outer 
feathers tipped and broadly edged externally with brownish gray; 
sides of head orange, this color deepest on the lores and paling to yel- 
low on the posterior auriculars; throat and sides of neck light gray; 
remainder of lower parts dull buff, palest anteriorly; lining ot wing buff.

the Cameroons. No other specimens are at present available for com- 
parison, so that it is impossible to add anything to his remarks. One 
of the present examples, probably an immature bird, has a conspicuous 
brownish tinge to the entire plumage, this most noticeable below, the 
abdomen being almost entirely devoid of any greenish shade.

One adult male, June 5, 1895. In process of molt, this particularly 
observable in the feathers of the wings, tail, throat, and sides of head. 
This example is slightly less velvety above than others of the same

duller below, with a much more deeply ochraceous superciliary stripe. 
Telophonus australis usshert seems to be a very good race, and some 
additional characters separating it from true australis are the darker 
shade of the upper surface, the rather lighter, less ochraceous super- 
ciliary stripe, and much paler auriculars. In the present specimen of 
ussheri the dark bars on the two middle tail feathers are much more 
indistinct than on any of the examples of australis available for com- 
parison.

Five specimens, two adults and three more or less immature. The 
former are sexed as males, and are apparently typical. One of them 
has a broad white tip to one of the right scapulars—evidently an 
albinistic marking. The immature birds differ in being rather lighter 
and browner above, with narrow fulvous tips to the greater wing-cov- 
erts, and in being washed with ochraceous below, most conspicuously 
on the breast and jugulum, though in one example quite strongly over 
nearly all the lower surface. The squamations on the chest are much 
less distinct than in the adult, being rather narrower, as well as paler 
and more brownish, 

Whether or not Fraseria should be included among the Prionopidse 
may well be questioned, but its scutellated tarsus indicates that it is 
not a thrush, although it has been placed in the family Turdide by 
Captain Shelley.’

DESCRIPTIONS OF TWO NEW SPECIES OF TORTOISES 
FROM THE TERTIARY OF THE UNITED STATES. 


By O. P. Hay. 


The species first to be described was collected by Mr. Charles Schu- 
chert, assistant curator, division of stratigraphic paleontology, U.S. 
National Museum. The specimen was found in the Zeuglodon beds of 
the Jackson formation of the Eocene, in Choctaw County, Alabama, 
near Cocoa post-office, on land belonging to Mr. James Brown. In the 
immediate vicinity, Mr. Schuchert collected also a nearly complete 
skeleton of Basilosaurus (Zeuglodon), some bones of Dorudon, and ver- 
tebre of the snake which has been described and figured by Mr. F. A. 
Lucas ! as Pterosphenus schucherti. 

The turtle was found lying imbedded in the rock with the plastron 
downward. The upper portion of the carapace had been planed off by 
denudation down to the upper borders of the marginals. It is there- 
fore impossible to determine the character of the neural and costal 
bones and of the various superior epidermal scutes. The remainder of 
the shell was intact, or nearly so, when excavated; but, in spite of 
careful packing, it suffered much in shipment to the National Museum. 
However, notwithstanding its broken condition, it has, under the intel- 
ligent supervision of Mr. Lucas, the Curator of the Division of Com- 
parative Anatomy, been so skillfully restored that little is left to be 
desired, so far as the plastron and most of the marginals are con- 
cerned. To Mr. Lucas I am indebted for the opportunity to study and 
describe this interesting relic. 

I have assigned this species provisionally to the genus Hadrianus of 
Cope. It undoubtedly belongs there, or to Testudo, or to some closely 
related genus. In order to determine this question definitely we need 
to have the upper portion of the shell. An examination of the diagram 
of the shell of Testudo ibera given by Boulenger? shows that the neurals 
and costals of this genus have undergone peculiar modifications. The 
neurals are alternately quadrate and octagonal, while the outer ends

PROCEEDINGS U.S. NATIONAL MUSEUM, VOL. XXII—No. 1181. 


22 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXII. 


of the costals are alternately very wide and very narrow. In Hadri- 
anus the elements of the carapace have not attained such differentiation. 

The species here described is named in honor of its discoverer. It 
will therefore be known as 


HADRIANUS SCHUCHERTI. 


The total length of the shell of this tortoise was originally close to 
75 em. (30 inches); its width, 52.5 cm. (21 inches). As will be seen from 
an inspection of Plate IV, the lateral borders of the shell are nearly 
straight, and parallel with each other. In front of the forelegs the 
margins round rapidly into the anterior border, so that in front the 
carapace is quite truncate. The hinder border approaches a segment 
of a circle. Neither the anterior nor the posterior margin is to any 
degree serrated. 

The marginals rise on the side of the carapace to a height of 10 em. 
The passage from the lower surface of the shell to the upper is quite 
abrupt; but this is due to a considerable extent, at least, to distortion 
from pressure. In living forms of Testudo the upper portion of the 
shell usually rounds gradually into the lower portion. 

The borders of the carapace over the openings for the posterior limbs 
are gently reverted; over the openings for the lower limbs the carapace 
is somewhat more strongly reverted. The caudal marginal appears to 
have descended without any upward flare. 

The plastron is concave; it has a length of 67.5 em. On a line 25 
mm. in front of the axillary notch the width of the anterior lobe of the 
plastron is 28cm. The tip of the lobe is prolonged into an obtuse angle. 
The tip is considerably thickened in front, but the borders are rather 
acute. The tip of the lobe was not prolonged in front of the carapace. 
In Hadrianus octonarius, the type of the genus, the plastron ends in 
front in a very broad and truncate lip. 

The width of the bridge is slightly more than one-third the length of 
the plastron. Measured on a line 25 mm. behind the inguinal notches, 
the width of the hinder lobe of the plastron is 30 em. This lobe is 
deeply notched on its hinder border. The posterior angles may, how- 
ever, have been somewhat more rounded than in the restoration. 

The entoplastron has a width of 15 em. Its hinder border can not 
be accurately traced, but its position was not greatly different from 
that represented by the dotted line on Plate V. The other bony ele- 
ments of the plastron have their boundaries shown on the same plate 
by means of the continuous zigzag lines. ‘They present no essential 
variations in form or position from those of modern species of Testudo. 

The conformation of the epidermal scutes, whose sutures are shown 
by the stippled lines in Plate V, is not, so far as can be determined with 
certainty, essentially different from that of the shields of recent species 
of Testudo. The gulars did not encroach on the territory of the ento- 
plastron. The humero-pectoral suture runs straight across the plastron 
until it approaches the axillary notch, when it turns abruptly forward. 


No. 1181. NEW SPECIES OF TORTOISES—HAY. 93 


The pectoral shields are extremely narrow in the middle line, but they 
widen right and left. The suture between the right and the left abdom- 
inal shields is very long, being contained in the length of the plastron 
only two and one-half times. There is present on each side an evident 
inguinal shield, and there were probably axillary shields, but they can 
not be demonstrated. I am not able to determine with certainty the 
position of the suture between the marginal shields and those of the 
plastron. In Testudo and its immediate allies this suture is well up on 
the marginal bones. In other genera, as Geomyda and Clemmys, it is 
located near the outer border of the plastral bones. In H. schucherti 
the suture between the pectorals and the abdominals gives off, near the 
outer border of the hyoplastron, what seems plainly to be a branch 
which is directed forward. This branch seems to me to be the anterior 
end of the suture between the plastral and the marginal shields. Ifsuch 
it is, it is quite different in position from that of species of Testudo. In 
the type of Hadrianus, a large and quite perfect shell, the sutures 
between the epidermal shields are very deep and distinet, but the 
sutures between the bones are usually very obscure. Nevertheless, I 
believe that here too the epidermal suture referred to lies on the plas- 
tral bones. : 

The second species of turtle to be described comes from coal-bearing 
strata of Miocene age. The particular locality is mine No. 4, near 
Roslyn, Washington. This town is located in Kittitass County, at the 
eastern base of the Cascade range of mountains. The deposit in which 
the turtle was found is known as the Roslyn sandstone. The preser- 
vation of the fine specimen is due to the intelligent interest of Mr. P. Y. 
Heckman, of Roslyn, from whom it was obtained for the U.S. National 
Museum. The Museum is indebted to Dr. F. H. Knowlton for his 
friendly offices in securing this species. 

The specimen displays only the upper surface of the shell; but this 
is almost entire and almost uninjured. Itis probable that the plastron 
is also present, but the matrix is so refractory that it has been thought 
best not to attempt to remove it. After a careful study of the carapace 
I have been unable to assign it to any of the described genera of Testu- 
dines. I therefore venture to propose a new genus for its reception. 
The specific name I derive from the collector of the specimen. The 
name of this new form is 


ACHERONTEMYS HECKMANI. 


Generic characters.—Carapace broad, rather depressed. Neural 
bones about as broad as long; mostly hexagonal, with the antero-lateral 
sides much shorter than the postero lateral. A single very broad pygal. 
Marginals 23 in number, coinciding with the outer ends of the cos- 
tals, instead of alternating with them. Vertebral shields very broad. 

Name derived from Acheron, a river of the fabled lower world, and 
emys, a turtle. ; 

Specific characters.—Carapace broad, rounded in front and behind. 


24 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL, XXII. 


No evidences of serrations on the border behind. Median line appar- 
ently occupied by a keel of low bosses. 

Surface of the carapace mostly smooth, with the impressions of the 
shield sutures distinct; areas occupied by costal shields with some 
longitudinal wrinkles. First neural nearly square; the eighth pentag- 
onal, with the anterior side very short. The single pygal extremely 
broad, extending across three marginals. The nuchal is considerably 
broader than long. Marginals quadrate; the lateral ones each placed 
opposite the end of a costal. The second and third vertebral shields 
enormous, extending laterally beyond the middle of the costals, the 
anterior border of the second vertebral occupying its usual position. 
Its hinder border thrown back to the hinder border of the third neural. 
The hinder border of the third vertebral not crossing the fifth neural, 
the usual position, but thrown backward to near the hinder border of 
the sixth neural. The fourth neural is thus made very concave in front. 
Costal shie!ds narrow, not one-half as wide as the contiguous verte- 
brals, alternate sutures between lateral marginal shields coinciding 
with sutures of costal shields. 

As to the relationships of this genus we can say nothing certain until 
we have at least had an opportunity to study the plastron. Neverthe- 
less its affinities appear to be with the Chelydridz, and we may place it 
there provisionally. It is of interest to compare the figure on Plate VI 
with the diagrams of the carapaces of Chelydra and Macroclemmys, 
found in Boulengevr’s Catalogue of Chelonians.! The carapaces of all 
three genera have the same general form; in all, the neural bones are 
closely similar; in all, the marginals lie opposite the outer ends of the 
costals, instead of alternating with the latter. In Cheiydra and Macro- 
clemmys, however, there are more or less extensive fontanelles between 
the costals and marginals. In both, the vertebral shields are of mod- 
erate width; in both, the hinder border of the shellis serrated. Length 
of the carapace, 181 mm; its width, 118 mm. 

Certain described genera of fossil turtles display vertebral shields 
as broad, perhaps, as those of the form here described. Among these 
may be mentioned Hylwochelys, which is figured by Dr. Lydekker.2 In 
this genus, however, the neural bones are long and narrow. Plesiochelys, 
a figure of which may be found in Zittel’s Handbuch, page 545, also 
has very broad vertebral shields; but here again the neurals are nar- 
row. Platychelys* is also furnished with broad vertebrals, but it is in 
many respects different from Acherontemys. The neurals are very irreg- 
ular in form and size; the carapace has a different form and is covered 
with large bosses. 

It is to be hoped that Mr. Heckman will be able, through the miners — 
in his employ, to secure other specimens of this species, so that the 
structure of the plastron may be determined.

A LIST OF THE BIRDS COLLECTED BY MR. R. P. CURRIE 
IN LIBERIA. 


By Harry C. OBERHOLSER, 
Assistant Biologist, Department of Agriculture. 


Although Mr. Currie’s trip to Liberia, under the auspices of the 
United States National Museum, was largely devoted to the collecting 
of insects, he nevertheless managed during his sojourn in that country, 
trom February 1 until May 10, 1897, to obtain a small series of birds. 
These specimens, 57 in number, were referred to the writer for deter- 
mination and report. They prove to represent 39 forms, 4 of which 
are here described as new, while another, Dryotriorchis spectabilis, is 
sufficiently rare to be worthy of special mention. AJ] the matter 
between quotation marks, together with the data relating to length, 
extent, colors of the unfeathered parts, as well as the Liberian, or 
English, and Golah, or native, names are from Mr. Currie’s notes. The 
writer is also in debted to him for information respecting the locality at 
which the birds were secured. 

Mount Coffee, where Mr. Currie’s collecting was done, is one of the 
numerous low hills along the St. Paul River, about 25 miles from 
Monrovia. The land, which begins to rise near the coast, attains in 
the vicinity of Mount Coffee an altitude of from 400 to 500 feet. The 
greater portion of the region is covered with heavy tropical forest, 
interrupted here and there by small clearings. The undergrowth in 
the forest is not particularly heavy, but abandoned rice fields are, 
under the influence of the hot, moist climate, rapidly converted into 
impenetrable thickets. The river, here about 100 yards in width, flows 
with considerable current over an exceedingly rocky bed and receives 
the tribute of numerous minor streams. These latter, particularly 
when they run through the forest, are, like the clearings, favorite 
resorts for birds.

Dryotriorchis spectabilis SHARPE,' Cat. Birds Brit. Mus., I, 1874, p. 279. 

One fine adult example of this rare hawk is in the collection. The 
entire upper surface, excepting the tail and the wing quills, has a dis- 
tinct slaty cast; otherwise this individual agrees perfectly with pub- 
lished descriptions. Length, 546 mm.; expanse, 953 mm. It was shot 
in the forest, and was in the act of swallowing a green snake, part of 
which was subsequently found in its throat. Mr. Currie states that it 
was very tame and unsuspicious. Golah name of the species, ‘See- 
pwah.” 

The specimen obtained by Mr. Currie is apparently the ninth of which 
any record has been published. All of these have come from a 
restricted area on the western coast of Africa extending only from 
Liberia to Gaboon. A list of those previously recorded is here added:

One adult male, taken April 22,1897. It is in fresh plumage with 
indications of a not quite completed molt. ‘Feet black;” length, 439 
mm.; expanse, 512mm. Called ‘‘Redwing” by English-speaking Li

1820, p. 6. 

A single specimen is in the collection, a young bird just acquiring its 
first plumage, killed April 16,1897. Although many of the feathers 
are still in their sheaths, and the wings and tail very imperfectly devel- 
oped, a brief description of the plumage may be of interest. Head, 
cervix, and tail dull black, the last with ill defined brown bars; back, 
scapulars, and upper surface of wings bright chestnut, heavily barred 
with black, these bars decreasing in width and regularity on the outer 
feathers of the wings; under surface vinaceous cinnamon, much paler 
on the middle of the posterior portion. This specimen is one of two 
which Mr. Currie kept for some time alive. (See Plate VII.)

rietobecommon. “Bill black; feet olive-green; iris crimson.” Called 
““Dry-time bird” in English; the Golah name is “‘ Way-dwa.” There 
is very little individual difference observable in these specimens, even 
in size. Two of them—one taken February 13, the other March 13— 
are molting the tail feathers.

One female, taken April 30, 1897. Length, 684 mm.; extent, 650 
mm. This is an immature specimen, with black throat, and agrees 
with the description of the young of leucolophus given by Mr. Ogilvie- 
Grant,! except for the presence of a conspicuous buffy white spot on 


the outer webs of most of the primaries. 


LOPHOCEROS SEMIFASCIATUS (Hartlaub). 


Buceros semifasciatus HARTLAUB, Journ. fiir Orn., 1855, pp. 356, 361. 
Lophoceros semifasciatus SHELLEY, Ibis, 1888, p. 59. 

A pair of adult birds is in the collection. According to Mr. Currie’s 
notes, both were shot in the forest near the clearing at Mount Coffee. 
The English-speaking Liberians call this species ‘Palm bird,” while 
the Golah name is ‘‘ Pwehah-pwehah.” 

One of the specimens was taken February 23, the other March 19, 
1897; both show indications of a molt not quite completed. The naked 
skin on the sides of the throat is slate black, not blue, as given by Mr. 
Ogilvie-Grant.? The feet and the bare skin encircling the eyes are also 
black. 

Male.—Length, 600 mm.; expanse, 800 mm. 

Female.—Length, 570 mm.; expanse, 800 mm.

Chars. gen.—Genus generi “Lophoceros” dicto affine, sed cauda 
valde cuneata, rostro prope recto, hujus cornu minimo, acute carinato, 
facile distinguendum. 

Type.— Toccus hartlaubi Gould. 

The strongly wedge-shaped tail, comparatively straight bill, with its 
very small, sharply keeled casque, to say nothing of conspicuous color 
differences, appear fully to justify the creation of a separate genus for

the species commonly known as Lophoceros hartlaubi. In fact, it bears 
less apparent relationship to the species with which it has usually been 
associated than it does to Ortholophus leucolophus. From Ortholophus 
the present genus may be satisfactorily distinguished by the absence 
of a conspicuous crest, and particularly by the comparative length of 
the tail, which is barely longer than the wing, instead of about twice 
as long. 
HORIZOCERUS HARTLAUBI (Gould). 


Toccus hartlaubi GOULD, Proc. Zool. Soc., 1860, p. 380. 

One adult male, just completing the molt, taken February 19, 1897. 
“Bill slate black, the tip dark red; feet slate color;” length, 406 mm.; 
expanse, 445 mm. The Liberian English name of this species is 
“‘Monkey-bird,” because of its alleged habit of following monkeys; in 
the Golah language it is called ‘‘ Hin-gongeh.”

DENDROMUS CAROLI ARIZELUS, new subspecies. 
Campothera caroli BUTTIKOFER, Notes Leyden Mus., VII, 1885, p. 221 (nec Mal- 
herbe). 

Chars. subsp.—Similar to Dendromus caroli, but entire under surface, 
including lower tail-coverts, clear uniform olive green, the spots appar- 
ently smaller and less numerous; these, together with superciliary stripe, 
lining of wing, light markings on outer webs of primaries, and inner 
webs of secondaries, strongly tinged with greenish, not buffy; spots 
on exterior webs of primaries much smaller; rufous area on side of head 
lighter and more yellowish; crown distinctly more olive greenish. 

Length, 178 mm.; expanse, 340 mm.; wing, 101 mm.; tail, 60 mm.; 
exposed culmen, 24 mm.; tarsus, 19 mm.; middle toe, 17 mm. 

Description.—Type, adult male; No. 161763, U.S.N.M.; Mount Coffee, 
Liberia, February 19, 1897; R. P. Currie. Above golden olive green, 
the head much duller, and its feathers tipped with dark red; a few 
more or less concealed spots of pale greenish on the feathers of the 
hind neck. Wings fuscous, the exposed surface when closed, in color 
like the back; outer webs of primaries with small spots of greenish 
yellow; inner webs of all the quills, at least basally, with wide inden- 
tations of the same color. Tail brownish black, the outer feathers with 
small lateral spots of greenish yellow. Under surface greenish olive, 
heavily spotted with greenish yellow, these markings largest posteriorly ; 
superciliary stripe greenish yellow; postocular region, including auric-

ulars, reddish chestnut; under wing-coverts and axillars light greenish | 
yellow with a decided buffy tinge. Bull in life slate color; tarsi dull 
light green. 

The single specimen obtained by Mr. Currie differs so much from a 
Gaboon example, as above indicated, that it without doubt represents 
an undescribed race, if, indeed, not a distinct species. It is evidently 
the same as Dr. Biittikofer’s specimens from Liberia, exhibiting all the 
differences from true caroli mentioned by him,! as well as others which 
apparently escaped his notice. The specimen at hand from Gaboon, 
the original locality of caroli, corresponds closely with published 
deseriptions of this form, and is apparently a typical example. No 
specimens from the territory intervening between Liberia and Gaboon 
have been available in the present connection; but the differences 
between carolt and arizelus are such as seem to indicate subspecific 
relationship, and arizelus has, therefore, been given a trinomial desig- 
nation.

STELGIDILLAS,? new genus. 


Chars. gen.—Genus generi ‘“‘Chlorocichla” dicto simile, sed maxille 
tcmii parte subterminali distincte serrata; nec corpore subtus clare 
flavescente. 

Type.—Andropadus gracilirostris Strickland. The uncertainty which 
has attended the determination of the proper generic affinities of 
Andropadus gracilirostris has led to the placing of this species in three 
different genera, with the characters of none of which does it suffi- 
ciently agree. From Criniger it may be at once distinguished by the 
depressed and slender bill—the maxilla with serrations on the cutting 
edge just posterior to the subterminal notch. The narrow, depressed 
bill separates it easily from either Andropadus or Hurillas, while from 
Chlorocichla, to which it seems to be most closely allied, it differs in 
the presence of serrations on the distal portion of the maxillar tomium. 
All the known species of Chlorocichla, moreover, are yellow or yellow- 
ish olive below, and the genus, as restricted by Captain Shelley,’ is a 
well-defined group. i 

The species described by Cabanis as Andropadus gracilis + is not per- 
fectly typical, but should apparently be associated generically with 
gracilirostris. The genus will then include Stelgidillas gractlirostris

Andropadus gracilirostris liberiensis REICHENOW, Novit. Zool., II, 1895, p. 160. 

One specimen, April 1, with molt not yet entirely completed. It 
agrees perfectly with Dr. Reichenow’s description of liberiensis which 
seems to be a sufficiently well characterized subspecies of Stelgidillas 
gractlirostris. 

The measurements of this example are: Length, 199 mm.; extent,

Two specimens, taken February 12 and April 28, respectively. Both 
are in worn breeding plumage; and the latter has apparently just 
begun to molt. One of them hasan appreciable wash of yellow on the 
lower tail-coverts. ‘Bill and feet black; iris reddish brown. The 
English-speaking Liberians know this species as the “Pepper bird;” 
in the Golah dialect it is called ‘“‘ Bweh-lay.”

Two adult specimens, male and female. The former is a very hand- 
some bird in perfect plumage; the latter agrees with Dr. Sharpe’s 
description of the supposed female,'! being very much duller colored. 
The upper parts, excepting, of course, the head, are considerably darker

than in the male, while the under surface, particularly the posterior 
portion, is lighter. 

Male.—Length, 190 mm.; extent, 203 mm.; “bill and feet bright blue 
black.” 

Female.—Length, 153 mm.; extent, 215 mm.; ‘bill dark horn, paler 
at base; feet blue black.” 

The Golah name of this bird is “‘ Wee-su-waw.” 


ARTOMYIAS USSHERI Sharpe. 
Artomyias ussh2ri SHARPE, Ibis, 1871, p. 416. 


Two specimens, adult male and female. The male is slightly paler 
and more grayish than the female, but otherwise identical. They agree 
with Dr. Sharpe’s description! except for the lack of whitish tips to the 
wing quills and greater coverts. These whitish tips are probably, as 
suggested by Dr. Sharpe,’ evidences of immaturity. 

These two individuals measure as follows: Male, length, 140 mm.; 
extent, 254 mm.; female, length, 142 mm.; extent, 264mm. It is inter- 
esting to notice the larger size of the female. The Golah name for the | 
species is ‘“‘ Bweh-bweh-dee.”

Certhia rectirostris SHaw, Gen. Zool., VIII, 1811, p. 246. 
Anthothreptes rectirostris GADOW, Cat. Birds Brit. Mus., 1X, 1884, p. 119. 


Four specimens. The two adult males appear not to differ from typ- 
ical examples, though one is rather lighter below than the other, besides 
being considerably smaller. Length, 99 mm.;? extent, 182 mm.; 
length, 112.6 mm.; extent, 173 mm. “Bill and feet black; iris choco- 
late brown.” 

Another specimen is sexed female with a query, and may possibly be 
an immature male. Length, 108 mm.; expanse, 167 mm. The upper 
surface is dull greenish olive with a conspicuous mixture of bronzy 
tipped feathers; the lesser wing-coverts are bronze green; the under 
parts are yellow, clearest on the median portion of the abdomen, shaded 
with olive green on the sides, paler on the throat and duller on the 
breast, both of which are slightly tinged with ashy. 

The fourth specimen is a young bird in first plumage, and is appar- 
ently rectirostris, although so young that without more specimens for 
examination it cannot be determined with absolute certainty. The 
upper surface is dull olive washed with greenish; wings dark brown 
with exterior edgings of golden olive; under parts pale dull yellow, 
the throat only washed with this color, as it is so imperfectly feathered 
that the slate gray bases of the feathers give their tint to the whole 
area.

ANTHREPTES COLLARIS HYPODILUS (Jardine) 


Nectarinia hypodilus JARDINE, Contr. Orn., 1851, p. 153. 

Two specimens, male and female. ‘Bill and feet black, iris brown.” 

Male.—Length, 109.2 mm.; extent, 148.5 mm. 

Female.—Length, 102 mm.; extent, 144 mm. The latter shows indi- 
cations of a molt not quite completed. 

This species is apparently divisible into three well defined geograph- 
_ical races. In southern Africa occurs Anthreptes collaris collaris; in 
southeastern Africa Anthreptes collaris zambesianus, and in the western 
part of the continent Anthreptes collaris hypodilus. True collaris dif- 
fers from both of the other forms in having the secondaries, greater 
and primary coverts edged externally with golden olive instead of 
metallic green; the posterior lower parts are much darker and duller 
yellow than in zambesiana; less orange yellow and more shaded with 
olivaceous laterally than in hypodilus. From hypodilus, with which it 
has usually been considered identical, zambesianus may be readily dis- 
tinguished by the much paler, less orange tinted posterior under sur- 
face, as well as by the paler shade of the exterior margins to second- 
aries, primary and greater wing-coverts. 


ANTHREPTES IDIUS, new species. 


Chars. sp.—Similar to Anthreptes fraseri, but decidedly smaller; the 
outermost primary scarcely more than half as long; rather darker, and 
much less yellowish olive green throughout. This most noticeable on 
wings and tail. 

Description.—Type, male (immature?), No. 161807, U.S.N.M.; Mount 
Coffee, Liberia, March 16, 1897; R. P. Currie. Upper parts dark olive 
green, rather duller on the head; wings fuscous, the lesser coverts, 
edgings of the others and of the quills, like the back; tail-feathers 
greenish olive, with broad olive green exterior margins. Sides of head 
and neck olive green; eye ring olive yellow; entire under surface deep 
olive yeliow, almost uniform, but rather paler on chin, and shaded 
with olive green on sides and flanks; lining of wing olive yellow. 
‘Bill dark horn, paler beneath; feet olive green.” Length, 122 mm.; 
extent, 178 mm. 

In details of structure and in pattern of coloration this new species 
is identical with Anthreptes fraseri, and does not need comparison with 
any of the other species of the genus. There is a possibility that dius 
may eventually turn out to be merely a geographical race of fraseri, 
but until such shall be proved to be the case it may stand as a species. 
The single specimen procured by Mr. Currie is sexed male, and if this 
be correct the absence of pectoral tufts, notwithstanding the lack of 
any other evidence, would seem to indicate immaturity; for it is quite 
probable, though of course not certain, that the aduit male would, like 
that of fraseri, possess these ornaments.

Three specimens—male, female, and young male. The two first are 
apparently typical birds in, breeding plumage; ‘bill and feet black;” 
length of female, 139 mm.; extent, 200mm. The immature male differs

wings and tail; the top of the head is sooty blackish instead of olive 
brownish; the sides of head and neck blackish slate instead of light 
brownish; the throat dull white, washed with olive yellow instead of 
light brownish, and sharply defined from the surrounding darker areas; 
breast and abdomen light olive green instead of brownish white; lining 
of wing sooty grayish instead of whitish. 

The Golah name of the adult male of this species is ‘‘ Zemeh-dee;” 
the young male is called ‘“‘Zemeh,” thus not distinguished from 
Anthreptes idius.

West Africa. General color glossy black, with bluish metallic reflec- 
tions, these most evident on the upper parts, nearly absent on the 
throat; top of head almost uniform with the back, though slightly 
greenish, as are the upper tail-coverts; wings brownish black, the lesser 
coverts like the back, the remaining coverts and the quills glossed

externally with greenish blue; tail brownish black, glossed exteriorly 
with greenish. 

Comparison of specimens from Fantee and Liberia with an adult from 
Gaboon seems to indicate the existence of two races of Dicrurus modes- 
tus. True modestus comes from Prince’s Island, and according to Dr. 


Sharpe! D. coracinus from Gaboon is identical with modestus, as it — 


should be from a geographical standpoint, thus leaving the northern 
form without a name. Dr. Sharpe also mentions! the more glossy 
appearance of specimens from the Gold Coast, but without separating 
them from modestus. 

Mr. Currie obtained one specimen, an immature male, apparently 
identical with examples from Fantee. Length, 225 mm.; expanse, 251

FRASERIA PROSPHORA, new species. 


Chars. sp.—Similar to Fraseria ochreata; the crown, sides of head, 
and neck not blackish, but uniform in color with the back; lower sur- 
face not pure white, the markings not sharply defined. 

Description.—Adult, sex undetermined, No. 161784, U.S.N.M.; Mount 
Coffee, Liberia, February 19, 1897; R. P. Currie. Upper surface uni- 
form slate color, slightly more bluish on lower back and rump; wing- 
quills and tail-feathers dull brownish black, edged externally with 
slate color; sides of head and neck like the crown. Lower parts 
grayish white; the sides and flanks slate gray; the jugulum a lighter 
Shade of same, spotted with darker; the feathers of breast and abdo- 
men with narrow slate-gray tips, producing a slightly squamated 
effect; lower tail-coverts each with a subbasal, V-shaped marking, 
and a narrow terminal bar of slate color; inferior wing-coverts brown- 
ish slate, the feathers broadly tipped with white; axillars white ter- 
minally, slate gray basally; thighs slate gray, edged with white. 
“Bill slate black; feet plumbeous.” Wing, 87.5 mm.; tail, 73 mm.; 
exposed culmen, 14 mm.; tarsus, 21.5 mm.; middle toe, 14 mm. 

This new form is distinguishable at sight from Fraseria ochreata by 
the lighter and uniform shade ef the upper surface, including the sides 
of head and neck; by the grayish instead of pure white under parts, 
the markings of which are much paler and much less sharply defined, 
giving a clouded and mottled appearance in place of a clear-cut 
squamate effect, particularly on breast and jugulum. The crissum is 
irregularly barred with slate color instead of being pure white. While 
it is barely possible that prosphora is a race of ochreata, and thus its 
representative in Liberia, yet the two birds are so different that until - 
the connection be established it seems better to accord them both 
specific rank.

A LIST OF THE BITING LICE (MALLOPHAGA) TAKEN FROM 
| BIRDS AND MAMMALS OF NORTH AMERICA. 


By VERNON L. KELLOGG, M. S., 
Professor of Entomology, Leland Stanford Junior University. 


Within the last few years a beginning in the systematic study of the 
North American Mallophaga has been made. This study has pro- 
gressed sufficiently to make it worth while to prepare a list of the Mal- 
lophaga so far recorded as having been collected from birds and 
mammals found in North America.’ By this is meant the record of col-. 
lection actually made from American host specimens, and not from host 
species common to both Europe and America, from which parasites are 
as yet recorded only from European host specimens. Where Mal- 
lophaga have been found common to American and European hosts, the 
foreign as well as the native hosts are given. As the synonymy for 
the species of Mallophaga found on American hosts has been given in 
both Professor Osborn’s and my own papers (these papers including 
practically all the American records), I have not repeated the synonymy 
in the list. All the American records as originally published are 
included in the list, no attempt having been made to correct the 
synonymy. Probably not more than half « dozen species in the list are 
liable to such correction. The American specimens referred to species 
originally found on European hosts have been so referred on the 
authority of the original descriptions and illustrations of European 
authors. The great importance of the correctness of these determina- 
tions, because of the interesting problems in distribution presented by 
this specific identity of European and American specimens, led me to 
take to Europe a large number of American specimens for the sake of 
comparison with the Huropean types. This comparison revealed the 
fact that these determinations of the identity of the American speci- 
mens with European species can be relied on. 

In addition to the list of parasites with hosts there is given also a 
list of hosts with parasites, so that reference to the American records 
can be readily made from either parasite or host. Students beginning 


1Some birds from Panama are included in this list. ‘‘ North America,” according 
to the American Ornithologists’ Union check list, ‘‘includes the continent of North 
America north of the present United States and Mexican boundary, and Greenland 
and the peninsula of Lower California, with the islands naturally belonging 
thereto.”

the study of the Mallophaga will soon discover the advantage of work- 
ing from the basis of known host. 

It is hoped that the list may serve as a convenient basis for the study 
of the phenomena of the distribution of the Mallophaga, one of the 
most interesting phases of the study of this group of insects. 

Types and cotypes of my own and of Osborn’s are now deposited in 
the U.S. National Museum. 


BIBLIOGRAPHY. 


There are very few records in the European literature of the Mallo- 
phaga of specimens taken from North American hosts. In very rare 
instances specimens have been taken from the skin of some North 
American bird in the collection of some European museum, or parasites 
have been collected in zoological gardens from representatives of some 
bird species peculiar to North America. For example, Piaget col- 
lected two species of Mallophaga from specimens of the Bob White 
(Colinus virginianus) and California Partridge (Callipepla californica) 
in the zoological garden at Rotterdam. I have since found. both of 
these species of Mallophaga on the same hosts in their native habitat. 
All of these records are referred to in the list. The following are the 
American papers containing the records upon which the list is based.

of the Mallophaga see Osborn' and Kellogg.’

CLASSIFICATION AND KEYS. 


The position of the Mallophaga among insects is discussed briefly in 
my New Mallophaga.* The latest classification of insects assigns to the 
Mallophaga the position of an independent order. ‘The affinities of the

order are in general with the platypterous pseudo-neuropteroid group 
comprising the Termites, Psocids, and Perlids, and are in particular 
with the Psocide. In the New Mallophaga! I refer to the correspond- 
ence between the peculiarly specialized mouth structure of the Mallo- 
phaga and the Psocid, and the recent careful study by Mr. R. E. Snod- 
grass” on the anatomy of the Mallophaga reveal other particulars of 
essential structural agreement between the two groups. 

As to the arrangement of the members of the order, I have proposed ° 
the adoption of a primary grouping into two suborders, corresponding 
with Nitzsch’s original division of the group into two families. In each 
of these suborders there are two families, one family of each suborder 
infesting mammals exclusively and comprising but a single genus, the 
other family of each suborder, comprising several genera, infesting 
birds exclusively. Mr. Snodgrass’s anatomical studies present new and 
‘important characters for the subdivision of the order which do not 
modify the original classification, but strengthen it and put it on a 
more thoroughly scientific basis. These new characters have been 
introduced into the following keys. I have made some other changes 
in the statement of the characters of the subordinate groups, based on 
my general study ot the order and use of the keys as heretofore pub- 
lished.

from Anas boscas, Anas carolinensis, Aythya americana, Aythya 
affinis, and Dafila acuta (Lawrence, Kansas), and from Merganser 
serrator (Kadiak Island, Alaska). Recorded by Osborn as “a 
very common species on many kinds of ducks. Specimens have 
been noted in the Cassino, Burnett, and Stejneger collections, 
and also taken at Ames, lowa.” Recorded by Kellogg and Chap- 
man from Aythya marila nearctica and Aythya affinis (Palo Alto, 
California). 

Recorded by European writers from Mergus albellus, M. merganser,

clypeata, A. crecca, A. stelleri, Fuliguia marila, F. ferina, and 
Mareca penelope. Recorded by Piaget as “sur toute espece de 
canards.” Piaget believes Docophorus natatorum Rudow,! from 
Platypus glacialis, Bernicla torquata, Chenalopex aegypticus, and 
Anas fusca, to be D.icterodes. He considers D. adustus Giebel,’ 
from a domestic duck, D. brevimaculatus Giebel,? from Anser albi- 
frons, and D. brunneiceps Giebel,’ from Anser cygnoides as varieties 
merely of D. icterodes. Piaget also refers to a Docophorus, from 
Podiceps cristatus, as a variety of icterodes.

SUMMARY. 

So far 282 species of Mallophaga have been recorded from North 
American hosts, of which 264 species are from birds and 18 from mam- 
mals, These species of Mallophaga represent 18 out of the 21 recog- 
nized genera. Ail of these genera except one (Giebelia) were estab- 
lished for specimens taken from European hosts. Of the 264 species of 
Mallophaga from North American birds, 107 are species originally 
described from European hosts (in 11 cases the American specimens 
being called varieties). The remaining 157 species were described from 
American hosts.

The sequence and nomenclature of hosts is, where possible, that of 
the American Ornithologists’ Union Check-list of North American 
Birds, second edition, 1895; where the hosts have been recorded under 
names not recognized by the Check-list I have, where the synonymy

doubtful records or references to vernacular names only of host, I have

NEW SPECIES OF NOCTURNAL MOTHS OF THE GENUS 
CAMPOMETRA, AND NOTES. 


By Joun B. Sm1TH, Se. D., 
Rutgers College, New Brunswick, New Jersey. 


The genus Campometra was described in 1852 by Guenee,! and the 
sole species and therefore generic type, amella, was figured (Pl. X VIIT, 
fig. 8). Mr. Grote never positively identified this species, although the 
picture is good and the markings are characteristic. In the Neumoe- 
gen collection he did note, however, to a specimen of Hubolina stylobata 
a Suggestion that it might be C. amella, and that proves to be correct 
without reasonable doubt. I have not seen the Guenée type, but both 
description and picture apply to stylobata and to nothing else. The 
type of stylobata I saw in the collection of the British Museum, and on 
direct comparison with the type of Homoptera integerrima Walker 
found the two identical. 

The synonymy then seems to be fairly well established, as follows: 
Campometra amella GUENEER, Sp. Gen. Noct., III, 1852, p. 25, pl. x vin, fig. 8. 
Homoptera integerrima WALKER, Cat. Brit. Mus., Het., XIII, 1857, p. 1057. 
Homoptera stylobata HARVEY, Can. Ent., VIII, 1876, p. 155. 

EHubolina stylobata GROTE, New List, 1882, p. 42. 

The genus Hubolina was described by Harvey? for his species impar- 
tialis, described at the same time, and that is therefore the type of the 
genus. In 1882 Mr. Henry Edwards described Hubolina mesket, and in 
the same year Mr. Grote referred Homoptera mima Harvey to Hubolina 
in his New List; the genns thus containing four species, two of which 
its describer had not considered as referable to it when they were 
characterized by him. 

EH. impartialis differs in color and general appearance from the allied 
forms, and on the female, which only I have at hand, the middle tibie 
are lengthily spinulated, the clothing close, the armature in a single 
series and very prominent. 

Campometra amella has the legs all shorter and quite densely clothed 
with hair and scales, the middle tibiz with apparently a few scattered 
spinules. In the male there seem to be no sexual tuftings on this 
member.

102 PROCEEDINGS OF THE NATIONAL MUSEUM. Vou. xxu. 


Homoptera mima has the tibie moderately clothed, not at all spinu- 
lated, in the male with distinct brush-like tufts of scales on the middle 
pair. 

HH. meskei is inaccessible to me at present writing, but its appearance 
is such that I would expect to find it in accord with the generic type, 
and to impartialis and mesket I would tentatively restrict the term 
Bubolina.! 

A close ally of C. amella in structure, size, and general type of macu- 


lation is: 
CAMPOMETRA BILINEATA, new species. 


Ground color umber brown, a little dusted with reddish. Head im- 
maculate. Collar a little paler at base, tipped with steely blackish. 
Thoracic disk intermixed with similar deep blue-black scales, which 
also sprinkle the patagiz and extend over the abdomen. Abdominal 
tuftings brown, gray scales becoming dominant at the sides and beneath. 
Primaries with clean, well-marked ornamentation. Basal line single, 
black, broken, accompanied by a brownish shade which breaks the 
otherwise solidly dark basal space, the tint being bluish black. Trans- 
verse anterior line single, upright, with a small outward bend just 
below the cell. Transverse posterior line single, red brown, irregu- 
larly crenulated, outcurved over the reniform, with a deep acute inward 
tooth in the submedian interspaces. Subterminal line incomplete, 
vaguely defined, white, slender, denticulate in the costal region, lost 
below that point except as it is marked by dusky clouds to vein 2, 
below which it is brown and slender to the margin. A broken blackish 
transverse line just before the margin. Just within the center of the 
wing are two upright, slightly wavy, prominent black lines, just enough 
sey arated to avoid a band. The inner is somewhat narrower, sharper, 
and more intensely black, the outer broader and a little diffuse. Orbicu- 
lar wanting in the specimen. Reniform large, irregularly oval, white, 
with narrow brown central lines. Secondaries a little more powdery and 
diffuse in ground color. A geminate black line at basal third, which 
does not reach either margin. A broad, dusky, submarginal shade, 
which is suffused with rusty reddish at its middle and terminates at 
the anal angle in a steely black spot. A broken, narrow, black termi- 
nal line and the fringes with a crenulated black interline. Beneath 
whitish, powdery, wings darkening outwardly. Primaries with an inner 
dusky band marked on the costa only, and an outer one which extends 
nearly half across the wing. Secondaries with an inner dusky band, 
which forms a lunule in the cell, a broken, diffuse, median shade and a 
submarginal clouding which forms a marked dusky patch above the 
anal angle. 

Expands 1.75 inches=44 mm. 


! Dr. Dyar informs me that the type of meskei is a male, has unarmed middle tibie, 
and no sexual tuftings. On general color and wing form the two may yet be held 
together until more material gives us better basis for other action.

Tyve.—No. 4316, U.S.N.M. 

Habitat.—Brownsville, Texas; June 10; Townsend, No. 544. 

A single female specimen from the U.S. National Museum. The 
resembiance to amella in size, form, and general appearance is obvious; 
but the distinctive feature, the parallel black lines near the center 
of the wing, is equally prominent. A further difference is that in 
amella the subterminal line is well defined, angulated and prominent, 
while in the new species this line is practically obsolete. It should be 
added to the description that an irregularly waved, somewhat diffuse 
bluish black band runs through the subterminal space and crosses the 
subterminal line at its inception on the costa. 


CAMPOMETRA CINCTIPALPIS, new species. 


Ground color a deep purplish red-brown, the primaries with elevated 
black, squamose vestiture that gives a velvety appearance. Front 
with a paie yellowish, transverse band, a pale tuft at base of each: 
antenna, and the palpi pale banded. Thorax purplish without defined 
markings, Primaries with an intermingling of pale and yellowish 
seales that gives a somewhat mossy appearance and obscures the ordi- 
nary maculation. Basal line faintly traceable by black scales. Trans- 
verse anterior line upright, blackish, a little wavy, preceded by a 
purplish shade which is itself limited by a darker brown, diffuse, 
Shading; followed by a mossy brown shade line. A narrow, black, 
irregular median line of elevated scales. ‘Transverse posterior line 
narrow, black, irregularly waved and toothed, squarely exserted 
over the reniform and almost as squarely inset beneath it; followed at 
some distance by a broader, less defined, and more even brown shading. 
Subterminal line distinet, pale, irregularly but not greatly sinuated. 
Orbicular small, round, incompletely and obscurely brown ringed and 
with a brown central dot. Reniform not defined, marked by a small 
upper and larger lower white spot, the two connected by a narrow, white 
line. Secondaries uniform smoky brown, the fringes with a pale inter- 
line. Beneath, primaries smoky, powdery, with a partial extramedian 
transverse line. Secondaries whitish, powdery at base, with a brown 
diseal spot and a crenulated brown median line, beyond which the wing 
is brown nearly to the margin, which is again whitish. 

Expands 1.35 inches=34 mm. 

Type.—No. 4315, U.S.N.M. 

Habitat.—Cocoanut Grove, Florida; E. A. Schwarz. 

A single defective female from the U.S. National Museum. ‘The 
apices of both wings are rubbed and broken, but the specimen is other- 
wise very fair, all the markings being discernible on one side or the 
other. It is the darkest species of the genus and has no contrasts in 
maculation. The immaculate secondaries will further serve to differen- 
tiate it from the other described forms. The middle tibia seems to have 
no obvious spinose armature, but has a central ring tuft of scales. 


104 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXII. 


CAMPOMETRA MIMA Harvey. 


The most common of the species, and as they run, very sharply defined. 
The transverse anterior line is geminate, both defining lines black, rather 
widely separated, the intervening space dusky so as to form an evenly 
outcurved dusky band. The transverse posterior line is also black, 
well marked, and squarely exserted beyond the reniform. A yellowish 
or reddish brown shade lightens the wing and dominates the impression 
gained by an ordinary examination of the species. 

The middle tibiz are unarmed and in the male have a very heavy 
scale tuft; but there are no hair pencils. 

Tene specimens are under examination: San Diego, Texas, April 
26, May 25; Bastrop County, and other Texan localities; Florence, 
Tucson, Catalina Springs April 11, Oracle, July 21, and other locali- 
ties in Arizona. The tendency in the variation is to a more indistinct 
maculation. 


CAMPOMETRA FRATERNA, new species. 


Resembles mima in all essential characters and differs from that 
species in the powdery, uniform ashen gray primaries lacking the 
brownish shadings, and on which the maculation is only feebly writ- 
ten. The transverse anterior line shows no tendency to band and, 
while the other lines and shades of mina are all traceable, none are 
well marked. In the structure of the middle tibie of the male the 
species is like its ally. 

Type.—No. 4313, U.S.N.M. 

I have six specimens, five of them females, from Death Valley (April), 
Oracle (July 7), and Catalina Springs (May 5), Arizona. All are from 
the U.S. National Museum, collected by Messrs. Koebele or Hubbard 
and Schwarz. 


CAMPOMETRA MINOR, new species. 


Smaller than mima throughout, few of the specimens exceeding and 
some not reaching 26 mmn., or a trifle over 1 inch, the primaries even, 
powdery gray, none of the markings well written, though so far as 
traceable, similar to mima, It is a slighter, narrower winged form than 
fraterna, which equals mima in average size and has the primaries 
more squared. No male of this species has been available. Of the 
five females four are from the Hulst collection, probably taken near 
Tucson Arizona, and one is from Catalina Springs (April 11), taken by 
Mr. Schwarz. The latter has a white shading over the reniform, 
extending beyond the transverse posterior line almost to the subter- 
minal line, the edges of this shade being indefined. The smoky margin 
of the secondaries is narrower than in the allied forms and there is less 
tendency to a banding. 

Type.—No. 4314, U.S.N.M. 


No. 1184. NEW NOCTURNAL MOTHS—SMITH. 105 


Altogether the species are left in a somewhat unsatisfactory condi- 
tion. Amella, bilineata, and cinctipalpis are probably congeneric and, 
except for a doubt about the armature of cinctipalpis, are strictly 
referable to Campometra. 

Mima, fraterna, and minor are close allies, yet I think, distinct, and 
they differ from Campometra in the totally unarmed middle tibia, which 
in the male is very heavily clothed with long scales forming a real 
tufting. I prefer leaving them with Campometra temporarily, until all 
the allied genera can be carefully studied, but suggest the term Heter- 
anassa in case generic separation seems desirable. 


SYNOPSIS OF THE SOLENID® OF NORTH AMERICA AND 
THE ANTILLES. 


By WiLu1AmM H. DALL, 


Curator, Division of Mollusks. 


In revising the group for the purpose of monographing the fossil 
species So many changes in nomenclature and distribution were found 
to be involved that it was thought the following summary would prove 
useful to students of the recent forms:

obliqua Spengler = 8S. ambiguus Lamarck. 
2. Solen (Solena) obliqua Spengler, 1793; Cuba, Porto Rico, St. 
Thomas. 
S. rudis Sowerby, 1874, not C. B. Adams, 1852; + philippinarwm 
Sowerby, 1874, not Hanley, 1845, are synonymous. 


Genus ENSIS Schumacher, 1817. 


(Ensatella Swainson, 1840, -- Solen Leach, 1852.) Type, Ensismagnus Schumacher. 


1. Ensis directus Conrad, 1843; Labrador to Indian Key, Florida. 
Pliocene to recent. 

i. ** americana Beck” of H. and A. Adams, 1856, is probably a manu- 
script name. Solen stliqua Chickering, 1855, not Linnzeus, 1758, is a 
synonym. This species was generally confounded with Solen magnus 
of Schumacher, under the name of Solen ensis Linneeus, by the earlier 
American authors.

2. Ensis minor Dall; Cape May to Florida and Texas. 

This is Solon ensis var. minor of some of the earlier writers, and bears 
to E. directus the same relation that Mnsis ensis Linneeus of Kurope 
does to the north European H. magnus Schumacher. It differs from 
the young of H. directus in having the valves wider behind than in 
front and relatively narrower as a whole.

1. Siliqua lucida Conrad, 1838; Monterey to San Diego, California. 

Confounded with the young of S. nuttallii by Carpenter, 1863, and 
Gabb, 1868; also, according to Conrad, with S. radiata Linneus. 

2, Siliqua media Gray, 1839; Okhotsk and Bering seas and north-

3. Siliqua patula Dixon, 1788,-Okhotsk Sea; the southern border of 
Bering Sea, and the Gulf of Alaska to Sitka. 

Described from Cooks Inlet, Alaska. The following names are 
synonyms: Solen maximus Wood, 1815, not Gmelin, 1792; S. gigas 
Dillwyn, 1817; S. grandis (Hinds Manuscript as of Gmelin) Dunker, 
1861, and Carpenter, 1863; S. splendens Chenu, 1845 and 1862. Large; 
with submedian beaks and straight rib. The following are discrimina- 
ble varieties, but apparently connected by gradations with the typical 
S. patula. 

4, Siliqua (patula var.) alta Broderip and Sowerby, 1829; Bering Sea 
and Strait. 

This is figured under the name of Culiellus costatus by Sowerby, 
Conch. Icon., 1874, but is not the costatus of Say. It is short and broad 
with very anterior beaks and straight rib. 

5, Stiliqua (patula var.) nuttallic Conrad, 1838, Lituya Bay, Alaska, 
south to Oregon, and California as far as Monterey. 

S. americana Chenu, 1845, may be the same, but I do not know it; 
S. californica Conrad, 1868, and 8S. nuttalt Sowerby, 1874, are synony- 
mous. The shell is very straight, brilliantly polished, narrower than 
the typical S. patula and with a much more oblique rib. The beaks 
are less anterior than in S. alta. 


NOTES. 


Solen tenuis Broderip and Sowerby, 1829, is unidentifiable, from the 
absence of a figure and the excessive brevity of the description. It is 
not the S. tenuis Gray, in Griffith’s Cuvier, 1833. It was collected by 
Belcher, whose shells came mostly from northwest America. 

Solen “ lineatus Spengler,” appears in Moérch’s Catalogue of Poulsen’s 
West India shells. It is probably intended for S. linearis Spengler (in 
Chemnitz) and may have been based on a misidentified specimen of 
Ensis nvinor. 

Solen niveus Hanley is listed by Guppy in his Paria fauna, 1877, and 
was perhaps based on a young specimen of WS. obliquus Spengler, or the 
following species: 

Solen lappeanus Dunker, Moll. Marina, 1858, is said to be from the 
Antilles, but has not been reported from that region by anyone else. 
Externally it is not unlike 8. viridis Say. 


IK) PROCEEDINGS OF THE NATIONAL MUSE UM. VOL. XXII. 


Aulus (= Siliqua) rostratus Dunker, 1861, figured by Sowerby, Conch. 
Icon., 1874, is said to be from the Arctic Ocean, but this is certainly 
erroneous. Solen radiatus Linnzus, appears in Pfeiffer’s list of Cuban 
sheils,! but the shell intended was very likely Tagelus divisus Spengler. 
No species of Siliqua is known from Cuba. 

Krebs cites Machera lucida “Gould,” from Morch’s Yoldi catalogue, 
as Central American; but this is doubtless M. lucida of Conrad, from 
the Pacific coast of Central America. 

There is no large species of Hnsis on the west coast of America corre- 
sponding to the H#. magnus and EH. directus of the northern Atlantic, 
though the H. californicus is the exact analogue of the European L. ensis 
and the east American H. minor. Among the Siliquas on the two sides 
of the continent 8S. alta and S. squama, S. media and S. costata, are 
respectively analogous, while S. lucida finds its counterpart in the 
S. pulchra of Japan. 


SOLEN MEXICANUS, new species. 


Shell small, straight, parallel-sided, with anterior beaks, the anterior 
end obliquely truncate; the posterior end squarely truncate with the 
corners slightly rounded off; hinge with the teeth normal, the ligament 
unusually long in a very narrow groove; shell white, covered with a 
polished olivaceous epidermis, longitudinally striate near the ventral 
edges of the valves. Length of shell, 60 mm.; of ligament, 11 mm.; 
width of valves, 8.5 mm.; diameter, 5.5 mm. 

Type.—No. 120634, U.S.N.M. Specimen from the Gulf of Tehuan- 
tepec. 

This species recalls the Solen linearis of Chemnitz, which, however, 
is considerably longer in proportion to its width. 


ENSIS CALIFORNICUS, new species. 


Shell small, slender, arcuate, the sides nearly parallel, the valves being 
Slightly attenuated toward the ends, beaks anterior, the anterior trun- 
cation bluntly rounded, the posterior similar; color white with livid 
pink streaks concentrically disposed; epidermis olivaceous brilliantly 
polished; hinge with small and very delicate cardinals (usually broken 
off), one in the right and two in the left valve, the dorsal ridge compara- 
tively strong and elevated, shorter than the ligainent. Length of shell, 
60 mm.; of dorsal tooth or ridge, 5.2 mm.; of ligament, 9 mm.; width 
of shell, 7 mm.; perpendicular to the chord of the are formed by the 
dorsal.margin of the valves, 2 mm. 

Type.—No. 158891, U.S.N.M. Specimen from 14 fathoms sand, off the 
island of San Pedro Martir, Gulf of California. Some specimens reach 
a length of 85 mm. 

This species recalls small specimens of the east American E. minor, 
which, however, differs by being wider distally than in front, larger 
when adult, with proportionately wider and more arcuate valves.

In this connection I may add some supplementary data to my 
“Synopsis of the Psammobiidz,”! which have come to hand since that - 
article was printed. 

Tagelus gibbus Spengler, as typically restricted, passes as far south 
as St. Thomas, West Indies, and probably to the northeast shores of 
Brazil. The variety called T. platensis by @Orbigny differs by being 
shorter and more attenuated behind, and I have seen it only from the 
southern coast of Brazil and Uruguay. Im all the typical species of 
Tagelus the posterior end is shorter than the anterior, the pallial sinus 
is deep, reaching to or forward of the perpendicular from the umbones, 
and the posterior adductor scar is rounded. The teeth are simple, 
erect, pedunculated, two in each valve. There is no central constric- 
tion or internal rib. Curiously enough, the shell figured by H. and A. 
Adams to illustrate Tagelus (or Siliquaria) gibbus is a Novaculina, 
while they describe the teeth as 3:2 (which is the dentition of Novacu- 
lina) and the sinus as deep beyond the umbones, which belongs to 
Tagelus and is untrue of Novaculina. 

Owing to the fact that a number of externally similar but really dif: 
ferent shells have been confused, the diagnoses of these groups are 
frequently inaccurate, and I have therefore reviewed the question in 
the light afforded by the specimens. The following are the characters: 


Genus NOVACULINA Benson, 1880. 


Type.—N. gangetica Benson. 

Beaks subanterior; teeth (when fully developed) three in the left and 
two in the right valve; the anterior left tooth often obsolete or wanting, 
the anterior right tooth bifid; there is no median constriction, the pal- 
lial sinus is small, not reaching the beaks, the posterior adductor scar 
rounded; the scar of the ventral side of the sinus not coalescent with 
the pallial line below it; situs in fresh water. 


Section CLUNACULUM Dall. 


Type.—Solecurtus mollis (Gould) Sowerby, Conch. Icon. Solecurtus, 
1874, pl. VI, fig. 26; coast of Brazil and Uruguay. 

Valves obliquely constricted, the constriction reflected by an internal 
thickened elevation (not a clavicle); beaks subanterior; teeth, two in 
the left and two in the right valve, the posterior left tooth bifid, in 
some of the species there is an obsolete tooth behind it; the pallial 
sinus not reaching the beaks, the posterior adductor scar triangular, 
the scar of the sinus coalescent ventrally with the pallial line; situs 
marine. 

Genus TAGELUS Gray, 1847. 

Type.—Solen gibbus Spengler. 

Valves not constricted and without a clavicle; beaks medium or sub- 
posterior; teeth simple, pedunculate, two in each valve; pallial sinus 


' Proc. Acad. Nat. Sci. Phila., 1898, pp. 57-62. 


112 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL, XXIL 


deep, reaching to or beyond the beaks, posterior adductor scar rounded, 
the scar of the sinus coalescent ventrally with the pallial line; situs 
estuarine or marine. 

Section MESOPLEURA Conrad, 1867. 


Type.—NSolen divisus Spengler. 

Valves arcuate, not constricted, but with a more or less perfectly 
developed clavicular rib extending ventrally from the submedian beaks, 
otherwise as in Tagelus. 

Gray in 1854 included species of Clunaculum under Novaculina as well 
as some species of true Tagelus like T. dombuji. I have not been able 
to examine all the described species, but Solen constrictus Lamarck, cer- 
tainly, and probably S. inequalis and S. complanatus Sowerby, belong 
to Clunaculum. 

TAGELUS POEYI, new species. 


Shell resembling a young 7. gibbus, but with more equal and evenly 
rounded ends, the beaks median, the teeth slender, long, but quite 
small, the nymphs for the ligament shorter and more central, the whole 
of the ventral side of the pallial sinus coalescent with the pallial line. 
Shell white, covered with a pale ashy gray, dehiscent epidermis; the 
anterior dorsal margin slightly decurrent. Length, 50 mm.; altitude, 
18 mm.; diameter, 11.5 mm. 

Types.—No. 27425, U.S.N.M., from Cuba (Poey); also from mouth 
of Old River, Belize (Stanton); beach at Greytown, Nicaragua (Dall); 
and Rio Grande do Sul, Brazil (Ihering). 

This species can be instantly distinguished from 7. gibbus by the dif- 
ferent form of the pallial sinus and the different position of the beaks. 
It does not appear to attain more than half the size of the full grown 
T. gibbus. 

Specimens of 7. gibbus collected at Matagorda Bay, Texas, by Sing- 
ley, of a light but distinct yellow color, are in the national collection, 
and more recently Hon. J. D. Mitchell has sent specimens, of which he 
has several in his collection, of a decided pink color, from the same 
vicinity. Both form a decided contrast to the white or slightly ferru- 
ginous tint of the average specimens of this species.

THE OSTEOLOGY AND RELATIONSHIP OF THE PERCOI- 
DEAN FISH, DINOLESTES LEWINI. 


By EDWIN CHAPIN STARKS, 


Assistant Professor in the Department of Biology and Curator of the Musewm, University 
of Washington, Seattle, Washington. 


As a preliminary to this paper I will quote a paragraph from a paper 
by Dr. Theodore Gill, ““On the identity of Hsox lewint with the Dino- 
lestes miillert of Klunzinger,” published about twenty-five years ago 
in the Annals and Magazine of Natural History. In it he gives the 
following concise history of Dinolestes: 


In the tenth volume (‘‘the class Pisces”) of the ‘‘Animal Kingdom” of Cuvier, 
edited by Edward Griffith (1834), are a figure (plate 60) and a brief notice (p. 465) 
of a fish which has long been a puzzle to me. It is called Hsox lewini and only 
noticed as follows: ‘‘Our figure of Esox lewini is from a drawing by Mr. Lewin, made 
in New Holland, of a species not hitherto noticed.” It was evident that the species 
thus named belonged neither to the genus Hsox nor anywhere near it; and (1) the 
relations of the fins, (2) the position of the ventrals with a spine and five rays each, 
(3) the form of the head, and (4) the teeth indicated for it affinity to Chilodipterus and 
allied forms; but no first dorsal fin was represented. The question then arose 
whether that fin had been atrophied (as in Aspidophoroides, Gobiopus, etc.) or (as was 
more likely) had been overlooked. After nearly forty years the species has been 
recovered, and singularly enough, after having escaped the observation of the num- 
erous collectors in the Australian seas for so long a time,' has in the same year been 
obtained and described by three different naturalists under as many names, viz, Dino- 
lestes miilleri by Klunzinger, Neosphyrena multiradiata by Castelnau, and Lanioperca 
mordax by Giinther. There can be no question about at least the generic identity of 
the Hsox lewini with the fishes described by the three contemporaries; and it now 
appears that the first dorsal fin exists, but is quite small, and sustained by only four 
or five spines. Klunzinger and Castelnau refer the type to the family Sphyrenide, 
and Giinther (with more justification I think) to the ‘‘Apogonina,” i. e., Chilodip- 
teride. 


This work was undertaken at Dr. Gill’s suggestion in the hope of 
finding, in a comparative study of the skeleton of Dinolestes with those 
of the Sphyrenide and the Cheilodipteride, some characters that 


'It is said, however, by Castelnau to be common [at Melbourne] in the months of 
May, June, and July; itattains 2 feet in length. The fishermen call it ‘‘ Ship Jack,” 
but that name is more particularly applied to Temnodon saltator.

would decide the question on which the authorities disagreed, as shown 
in the last sentence quoted from the above paper. 

It would appear an easy matter to place this form under one or the 
other of two families arranged in different suborders, as the Sphyrzn- 
ide and Cheilodipteridz usually are: but the fact that two of the 
authorities consider it under one family and two under the other, indi- 
cates how close the resemblance must be to either. 

Sphyrena argentea is the form chosen to represent the family Sphy- 

renidz, while the only representative procurable of the Cheilodipter- 
idz was Apogon maculatus. 

The skeleton of Apogon was found to be of but little pasieienoe’ in this 
comparison. Though being undoubtedly Percoid, it differs as much 
from Dinolestes as they both differ from the more generalized Percoids, 
such as the bass or perch. Considering the difference between Dino- 
lestes and Apogon in external appearance, we have probably little reason 
to expect the internal resemblance to be otherwise. Perhaps if one of 
the Sphyrena-like Cheilodipteroids could be examined there would be 
a closer resemblance. 

To be sure Dinolestes differs from Apogon only in shape and compar- 
ative size of elements (that is, comparative between corresponding 
elements of each species), and not in arrangement, or lack or posses- 
sion of elements; but it is so very different in shape of cranium, form 
of body, and shape of fins that it would seem better to consider the 
Cheilodipteroid side of the question partly by considering the Percoid 
fishes more or less as a whole. Though, of course, if it is placed with 
the Percoids it is only under the family Cheilodipteridz, as the Per- 
coids are now arranged, that Dinolestes could be admitted. 

Were it not that the ventrals of Dinolestes are apparently thoracie, it 
might appear after a superficial external examination to be related to 
Sphyrena. The long head, projecting lower jaw, fanglike teeth, and 
elongate preorbital region are very Sphyrena-like. The shape of the 
body and dorsal fins are also suggestive of that relationship. 

In internal characters we find that the ethmoid is wide and flat, some- 
what overlying the vomer and prefrontals instead of being interposed 
between them. This is the condition found in Sphyrena. The nasals 
are very much like those of Sphyrena, being long-and channeled and 
attached by their sides to the ethmoid for nearly their whole length. 
This, however, is probably caused by the elongate snout, and goes with 
it as a part in keeping with the surrounding conditions. It disposes of 
the characters by which an alliance with Sphyrena could be proved. 

Though the shape of the body and head, the canine teeth, and dorsal 
fins exhibit perhaps a closer superficial resemblance to the Sphyranidz 
than to the Cheilodipteridz, there are forms to be found in the latter 
family which approach this Sphyrena-like appearance also. These 
characters therefore denote nothing in favor of either relationship. 
The characters of the ethmoid and nasals are the only characters pos- 
sessed by Sphyrena in common with Dinolestes that are not also slfared

in by members of the family Cheilodipteride. They are of no great 
importance. 

_ his, as has been said, is without considering the position of the 
ventrals. As the Percoid fishes have thoracic ventrals, and the mem- 
bers of the suborder Percesoces, under which the Sphyrenid is 
placed, have abdominal ventrals, it is difficult to see how Dinolestes 
could have been thought to be related to Sphyrena unless the ventrals 
were interpreted as being abnormally anterior abdominal ventrals. 
The ventrals, however, prove to be typical thoracic ventrals with the 
anterior point of the pelvic girdle interposed and attached between 
the opposing clavicles near their lower end above their symphysis. 
Anterior abdominal ventrals might have the point of the pelvic girdle 
touching the clavicles or even extending slightly under them, but 
never interposed between them. 

Another character that refutes the Sphyrzenoid relationship of Dino- 
lestes is the lack of the long processes developed backward from the 
epiotics and supraoccipital crest, which are possessed in a greater or 
less degree by all the Percesoces and reaches its greater development 
in Sphyrena. 

A more important difference is the structure of the teeth. Though 
both Dinolestes and Sphyrena have large backward-directed canines, 
they are entirely different in the way in which they are attached to 
the bone of the jaw. The calcified tooth substance of the teeth of 
Dinolestes reaches only to the bone, where it is anchylosed or so incor- 
porated with the bone as to make it difficult to distinguish the line of 
junction. This attachment is effected by what Tomes calls “bone of 
attachment.” A substance resembling cement, but unlike true cement, 
is developed from the periosteum rather than from the dental capsule. 
Such teeth may be developed from sockets, but as the calcified tooth 
substance 1s pushed out the cavity behind fills with the bone of attach- 
ment and becomes obliterated. The dentine never extends into a 
cavity of the bone in the mature tooth. This is a Percoid character. 

The teeth of Sphyrena, on the other hand, are set in sockets. The 
attachment of teeth in alveoli is of such rare occurrence among fishes 
and must be so deep seated that we can hardly interpret it as less than 
a family character. Mr. W. G. Ridewood, in a paper,' has this to say 
in regard to this class of teeth: 

The tooth and bone are in organic continuity by means of a periosteal layer com- 
mon to the tooth and the jaw; and this layer may remain uncalecified so that the 
teeth can be pulled out of their sockets, as in some Caracinoid fishes; or ‘‘ bone of 
attachment” may, except in young teeth, anchylose the tooth to the wall of the 
socket, e. g., Sphyrena. 

But whether or not the tooth becomes cemented in, the enamel and 
dentine extend into a cavity and do not become incorporated with the 
bone. 


‘Natural Science, VIII, June, 1896, p. 383. 


116 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XU. 


There is also a difference in the shape of the teeth of Sphyrena and 
Dinolestes. Those of the former are lancelike—that is, compressed 
laterally and with cutting edges. Those of the latter are round in 
transverse section. 

The vertebre of Dinolestes are typical, or in general resembling the 
Percoids and most bony fishes in that they are of moderate length and 
not much constricted in the middle. They have parapophyses devel- 
oped behind the fourth vertebra, two pits on the side of each vertebra 
separated by a longitudinal ridge, and the abdominal vertebre with a 
pit on the ventral side with ridges on each side of it. The vertebre of 
Sphyrena are long and smooth with scarcely any pits, much constricted 
in the middle, making them hourglass shaped, and wel only one or 
two pairs of parapophyses. 

The shape of the cranium of Dinolestes is also more typically Percoid 
in appearance than Sphyrenoid with the slightly rising supraoccipital 
crest and more wedge-shaped lateral view. 

A recapitulation with these points condensed will show at once the 
affinity of Dinolestes to the Cheilodipteride. 

1. The Percoid appearing cranium. 

2. The thoracic ventrals. 

3. The anchylosed teeth rather than teeth in sockets. 

4, The character of the vertebrae, typical; not specialized as in ~ 
Sphyrena. 

5. The lack of the long posterior processes from the epioties. 

These conclusions are fortified by the following description.

DESCRIPTION OF TWO NEW SPECIES OF CRAYFISH. 


By W. -. Hay, M. S., 
Central High School, Washington, D. C. 


In working over the large collection of the Astacidze in the posses- 
sion of the U. S. National Museum the following new species have come 


to my notice: 
CAMBARUS PILOSUS. 


Type locality.—Beloit, Mitchell County, Kansas. 

Type.—No. 19761, U.S.N.M. 

Male, form I, not known. 

Male, form II, rostrum of medium width, long, deeply excavated, 
with sharp, raised, slightly converging margins; lateral teeth well 
developed, acute; acumen long, slender, acute, nearly straight. Post- 
orbital ridges grooved on their outer face; anterior spines small, acute. 
Carapace smooth and lightly 
punctate above, very finely 
granulateon thesides; anterior 
border not angulated and with 
a well-developed fringe of cilia 
extending along the lower side 
of the rostrum and around 
beyond the minute branchi- 
ostegian spine; cervical groove 
deep, sinuate, broken on the 
sides above the small lateral 
Spine; areola narrow. Abdo- 
men longer than the cephalo- 
thorax, telson rounded behind, 
anterior segment with two spines on each side of the posterior border. 
Second and third basal segments of the antenne with well-developed, 
acute, external spines. Antennal scale a little longer than the rostrum, 
outer margin slightly concave, apical spine acute and rather long; tip 
concave, inner margin rounded. Epistoma subtriangular, the margins 
convex. Third maxillipeds hairy on their inner and outer faces. Cheli- 
peds short; chele of moderate width, punctate above, nearly smooth

and sparsely ciliate below; upper surface near the inner margin and 
both fingers thickly ciliate; inner border of hand short, serrate, the 
serrations hidden by the cilia; outer margin of hand ribbed; movable 
finger serrate and ciliate on outer margin; both fingers ribbed on upper 
surface and bearded at base on inner margins, the beard being most 
dense on the outer finger. Carpus triangular, lightly grooved above, 
ciliate along the distal margin; a small spine at the superior internal 
angle and behind it a few very minute denticles, inner surface heavily 
bearded along the distal margin; median spine large and curved strongly 
forward; distal border beneath ciliate, and with three well-developed, 
acute spines. Distal margin of meros bearded above and within, two 
small spines above at the distal end; beneath, of the usual two rows of 
spines, the outer row is represented by two or three strong spines, the 
inner by a row of small teeth; between the rows there is, in some speci- 
mens, a ciliated patch. Third pair of legs hooked. First pair of 
abdominal appendages of medium, length, reaching forward to the 
middle of the basal segments of the second pair of legs, very slender . 
and bifid for only a short distance from the tip; inner branch con- 
siderably shorter than the outer, the tip acute and turned slightly 
backward and outward across the outer branch, the tip of which is com- 
pressed and recurved. 

Female.—Not known. 

Seven specimens, the largest nearly 2 inches in length. 

In some respects this species resembles quite closely Cambarus nais 
Faxon, from the same region. I have not been able to compare Dr. 
Faxon’s types with the species. here described, but as his description 
makes no mention of the heavily ciliate chelipeds, a character which 
could not have escaped his observation, and fails to agree in other 
respects, I feel no hesitation in considering the specimens from Beloit 
representatives of a new species. 


CAMBARUS CLYPEATUS. 


Type locality.—Bay St. Louis, Mississippi; U. S. Biological Survey, 
collector, 1892. 

Type.—No. 22778, U.S.N.M. 

Male, form I, not known. 

Male, form II, not known. 

Female.—Rostrum long, very broad, flat, hardly at all excavated, 
sides slightly raised, sharp, diverging slightly from the base to about 
the middle, then converging to near the tip where they abruptly turn 
in to the middle line; the tip of the rostrum is round, and the usual 
lateral teeth are not represented, even by angles. Postorbital ridges 
short, grooved on outer face, anterior spines wanting. Carapace 
smooth and polished above, lightly punctate on the sides, anterior 
margin hardly angulated; cervical groove sinuate, broken on the sides; 
lateral spine wanting; branchiostegian spine minute; areola wide. 


No. 1187. TWO NEW SPECIES OF CRAY FISH—HAY. 123 


Abdomen longer than the cephalothorax; pleure punctate; telson 
rounded behind, anterior segment with four or more spines on each 
side of the posterior border. Antenne shorter than the cephalothorax; 
antennal scale shorter than the rostrum, broadest near the middle, tip 
convex, inner margin rounded. Epistoma broader than long, sides 
convex, anterior angle denticulate. Third mavxillipeds hairy on their 
inner faces. Chelipeds 
moderately strong; 
chele inflated, punctate 
above and below; inner 
margin of hand longer 
than the fingers; outer 
finger short, nearly 
straight, inner finger 
rather strongly in- 
curved at tip; both fin- 
gers strongly ribbed 
above and provided on 
their cutting edges with 
two or three large teeth 

Fic. 2.—Nos. 1, 2, CARAPACE; NO. 8, CHELA; NO. 4, ANNULUS 
and numerous serra- ee eee 
tions. Thoracic ster- 
num hairy. Annulus ventralis prominent, subcircular, the wall bitu- 
bereulate and thin in front, broad and low behind. The fissure is very 
sharply bent to one side just within the anterior wall and is lost, but 
an accessory branch, separated by a thin wall from the first, bends back 
to the middle of the annulus and emerges at the posterior angle. The 
appendages of the first abdominal somite are not developed. 

A single specimen about 2 inches in length. 

As no specimen of the male of this species has yet been collected, it 
is impossible to say with certainty where this species belongs. In gen- 
eral appearance it is very unlike any other North American species 
yet discovered. In the rounded, toothless rostrum and the peculiarly 
shaped chele it resembles somewhat some of the South American 
Parastacine, but the resemblance stops there. The closest relatives 
will probably be found to be some of the species of the second group of 
Faxon, and of these Cambarus cubensis approaches it most closely in 
appearance. 


CONTRIBUTIONS TO THE NATURAL HISTORY OF THE 
COMMANDER ISLANDS:! 


No. XIII.—A NEW SPECIES OF STALKED MEDUSA, HALICLYSTUS 
STEJNEGERI. 


By K. KISHINOUYE, 


Imperial Fisheries Bureau, Tokyo. 


A large number of medusz, belonging to the very interesting family of 
Stauromedus, were collected by Mr. Leonhard Stejneger at Nikolski, 
Bering Island, one of the Commander Islands, during the summer of 
1897. These medusze were preserved in formol and still remain in 
excellent condition. They belong toa single species of the genus Hali- 
clystus. So far as I am aware, there are only three known species of this 
genus, and all of them are from the Atlantic coast. The species, how-

ever, differs in many points from those already known, and it is so far 
the only representative of the genus Haliclystus found on the Pacific 


coast. 
HALICLYSTUS STEJNEGERI, new species. 


Type.—No. 18942, U.S.N.M. 

Habitat.——Bering Island, North Pacific Ocean. 

The medusa is funnel-shaped and has a rather short peduncle. The 
largest specimen of the collectionis 18 mm.in height (including the pedun- 
cle)and 18 mm.in diameter. The peduncle is 53mm.inheightand25mm. 
in breadth. I shall give a short description of such larger specimens. 

The preserved specimens are grayish or pale brown, semitransparent, 
with a dark brown or nearly black streak at the umbrella margin and

each perradial corner of the peduncle (figs. 1, 2). Besides these there 
are 16 radial streaks of the same color (fig. 1). Each two of these 16. 
streaks are paired along the adradii, and each two adradial pairs unite 
together in turn at the perradii at the junction of the umbrella (some- 
times called the calyx) and the peduncle. These dark streaks are found 
in the exumbrella. In the subumbrella, too, a dark streak is found at 
each perradial edge of the esophagus, and moreover there are pigment 
cells around the genital sacs. In all these cases the pigment is found 
in endoderm cells. zr 

The umbrella, or the so-called calyx, is funnel-shaped or conical, 
gradually increasing in breadth from the pedunele to the umbrella 
margin. The breadth of the umbrella is one and one-third to one 
and one-half times as long as its height. 


no.1188. 4 NEW SPECIES OF STALKED MEDUS_E—KISHINOUYE. NG 


The peduncle is nearly quadrate in cross section. It is about half 
the length of the umbrella. It has four interradial longitudinal 
grooves which are formed by the attachment of the teniola (fig. 1). 
These teniola meet at the longitudinal axis and divide the internal 
space of the peduncle into four chambers. The demarcation between 
the umbrella and the pedunele is distinct. 

The exumbrella is smooth, without prominent ridges or groups of 
nematocysts. The gelatinous layer is equally thin everywhere and 
firm in consistence. In the subumbrella we find a few small groups of 

-nematocysts at the perradial sinuses of the umbrella margin only. 

The muscle plates are as 
in other species. The per- 
radial muscles are more 
weakly developed than the 
interradial. The four in- 
terradial infundibular deep- 
eningsnearly reach the junc- 
tion of the umbrella with the 
peduneles. 

The umbrella margin is 
cut into eight adradial arms, 
which are equal in size and 
equally distant from each 
other (fig. 2). The depth of 
the incisions is about half 
the length between a princi- 
pal tentacle and the pedun- Fig. oe a ee ne SPECIES. VIEW

bunch of tentacles, 70 to 100 
in number. Tentacles are of equal thickness, but they differ in length. 
Their length decreases gradually as they approach the periphery of 
the bunch. : 

The eight principal tentacles are transformed into adhesive marginal 
bodies (figs. 1, 2). They are large, sessile, egg-shaped, and about one- 
half as long as the diameter of the peduncle. 

The cesophagus or manubrium (fig. 2) is short, quadrangular, as in 
other species of Haliclystus. Its wall has many longitudinal folds, and 
its free margin is reflected outward. The eight rows of well-developed 
gastral filaments extend from the+base of the cesophagus to the 
proximal end of the genital glands. 

Genital glands are eight in number, broad and leaf-shaped, tapering 
at both ends. They extend almost along the entire length of the. 
umbrella. As they are touching each other along the proximal half 
their length (fig. 2), the subumbrella is almost entirely occupied by 
them. Hach gland consists of 100 to 150 round saes. These sacs are 
not arranged in rows. Those nearest to the perradii are larger than 
the others. We find six to eight sacs abreast at the broadest part of

128 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXII. 


each gland. Each gland is turned over at the perradial sides and forms 
a part of the mesentery (fig. 2). 
Small specimens (3 to 4 mm. in umbrella diameter) of the collection 
differ more or less from larger specimens in the proportion of the parts 
of the body, number of tentacles, and genital sacs, etc. Generally, 
smaller specimens have the narrower umbrella, longer peduncle, shorter 
arms shallower umbrella cavity, fewer and not much crowded genital

sacs, and a very little pigment in endoderm epithelium. Moreover, the 
genital sacs vary in size much more greatly than in larger specimens. 
The peduncle is not four-chambered. Such differences may be easily 
understood by comparing figs. 1 and 2 with fig. 5. 

Almost all the specimens of the collection were found to contain a 
number of Gammarus in the stomach.

~ DESCRIPTION OF A NEW SPECIES OF IDOTEA FROM 
, HAKODATE BAY, JAPAN. 


By HARRIET RICHARDSON. 


Two distinct species were included by Miers! with Idotea ochotensis 
Brandt. Ina former paper’? the author has endeavored to define the 
limits of Idotea ochotensis on the one side by preserving the specitic 
distinctions of Idotea rectilineata Lockington. It is the object of the 
present paper to further define the limits of Idotea ochotensis on the 
other side by showing the specific differences of another species, for- 
merly included. Two specimens from Hakodate Bay, Japan, in the 
collection in the U. S. National Museum, when compared with a large 
series of f. ochotensis from various localities, extending all the way 
from Kamchatka to Bering Sea and the Aleutian Islands, confirms the 
impossibility of uniting them with I. ochotensis. The specimen which 
Miers saw in the British Museum collection from Yeddo Island, and 
which he figures, undoubtedly belongs to the same species as our two 
specimens from Hakodate Bay. In regard to it Miers says: 

It differs from Brandt’s figure of J. ochotensis only in its relatively longer and 
slenderer body and somewhat shorter antenne, which when retracted would not 
reach to the posterior margin of the fourth thoracic segment, but whose pedun- 
cular joints are longer than in Brandt’s figure. 

Further on he speaks of the tooth at the distal extremity of the 
terminal segment as being very prominent in the specimen from 
Japan. It is probable that Miers had specimens of all three species, 
the one spoken of obtained at Vancouver Island being J. rectilineata 
Lockington, the specimen from British Columbia being J. ochotensis 
Brandt, and the Japanese specimen the one herein described. 

In comparing the species, specimens have been selected which are of 
nearly the same size, in order to better compare the corresponding 
parts.

This species differs from J. ochotensis Brandt in the following points: 
1. The proportions of the body. J. 
ochotensis is stouter and shorter, the 
relative proportion of breadth and if 
length being 2:7, while in J. japonica 
the body is longer and narrower, the 
relative proportion being 2:10. 
2. The proportionately greater 
length of the second pair of antenne.! 
In J. ochotensis the joints of both 
the peduncle and the flagellum are 
stouter and shorter and the antennze

while in I. japonica these joints are

1 Although there is some variation in the length of the second pair of antenne of 
Idotea ochotensis, nevertheless these antennz are always shorter than those of Idotea 
japonica in specimens of the same size, and the peduncle of the antennz is also 
shorter.

3. The form of the antero-lateral angles of the first thoracic segment. 

In I. ochotensis these angles are markedly truncate, while in the 
present species they are rounded. 

4, The narrower epimera in J. japonica. 

5. The shape of the terminal segment. 

In I. ochotensis the lateral margins of this segment are concave, the 
lateral angles prominent and rectangular, the median posterior tooth 
or apex not greatly produced, while in J. japonica the lateral margins 
are straight, the lateral angles less prominent and obtuse, and the 
median posterior tooth or apex greatly produced, being twice the length 
of that in I. ochotensis.

LIST OF SHELLS COLLECTED BY VERNON BAILEY IN HERON 
AND EAGLE LAKES, MINNESOTA, WITH NOTES. 


By RoBERT EH. C, STEARNS, PH. D., 
Honorary Associate in. Zoology. 


- The species listed below have been received at various times from 
the United States Department of Agriculture. They forma part of the 
collection of the United States National Museum, and were collected 
by Mr. Vernon Bailey, an assistant in the Division of Biological 
Exploration, in charge of Dr. C. Hart Merriam. 

Heron Lake is in southwestern Minnesota, in Jackson County, near 
the Iowa line. The material from this place was, to quote Mr. Bailey, 
“scraped up on the beach,” in 1887. 

Eagle Lake is in Sherburne County. This county is nearer the cen- 
ter of the State, being rather south and east of the center. The collec- 
tions from both places are small, so far as the number of species is 
considered, but not without interest, as certain forms, which are com- 
mented on at some length, indicate peculiar environmental conditions. 
These conditions can only be surmised from the material itself, in the 
place of personal investigation of the lakes and their waters as well 
as the immediate region in which they are situated. Thetestimony of the 
numerous examples.of Planorbis trivolvis from Heron Lake and Limnea 
emarginata from Eagle Lake points to considerable fluctuation in the 
volume of the water one season compared with another, and in the 
more northerly Kagle Lake to the influence of extreme cold, or alterna- 
tions of temperature conditions as related to volume of water in some 
Seasons or years, as well as possible alkalinity or some chemical fluctu- 
ation due to diminished volume of water at times, or, briefly, to fluctu- 
ations in the quantity and temperature of the waters and the chemical 
quality or proportions in the same. 

The Eagle Lake shells were collected in 1891.

' Eagle Lake; abundant. Of the total number of shells from this lake, 
nine-tenths belong to this species and its varieties, numbering, perfect 
and imperfect being counted, probably four hundred examples. 


A. Normal form (Cat. No. 123887, U.S.N.M.); smooth; spire modera- 
tely elevated; rather solid and ventricose; columellar fold or twist, 
rather strong. 

B. Spire short (Cat. No. 123888, U.S.N.M.); rather thin and ventri- 
cose, ranging from young to adult. 

©. Body whorl shouldered above (Cat. No. 123889, U.S.N.M); spire

surface smooth; some individuals marked by strong incremental lines; 
others inconspicuously lirate; young to adult. 

E. Malleated; obtusely irate (Cat. No. 123891, U.S.N.M); in some 
examples partially obtusely lirate; others showing sharply developed 
growth lines; spire moderate; shell rather solid; aperture effuse; 
numerous examples.

includes juvenile examples of many of the foregoing, and other varietal 


facies. 
PLANORBIS TRIVOLVIS Say. 


Heron Lake; abundant (Cat. No. 104462, U.S.N.M.). A dwarfed and 
apparently arrested form of this widely distributed species was obtained 
in great numbers by Mr. Bailey. The largest individual measured, 
maximum, only 12.50 mm., while the average of numerous examples is 
not over 9 mm.,maximum. There are two varietal forms, which point 
to hybridization, suggesting campanulatus in one direction and bicari- 
natus in the other. Among 143 perfect individuals, 6 exhibit the abrupt 
varicose character of aperture so conspicuous in campanulatus, and there 
are many examples that lean toward bicarinatus, with a pretty sharp 
angle on the upper and an obtuse keel on the under side of the whorls. 
These are registered in the United States National Museum, as follows: 

P. trivolvis var. A (Cat. No. 104463, U.S.N.M.).

obtained. 
PLANORBIS PARVUS Say. 


Heron Lake (Cat. No. 104461, U.S.N.M.); Eagle Lake (Cat. No.

It is presumable that these lakes contain many species not mentioned 
above. It should be borne in mind that no attempt was made by Mr. 
Bailey to make an exhaustive collection of the molluscan life in these 
bodies of water; he simply collected such material as came readily to 
his hand without interfering with his special work. 


DESCRIPTION OF A NEW VARIETY OF HALIOTIS FROM 
CALIFORNIA, WITH FAUNAL AND GEOGRAPHICAL 
NOTES. 


By RoBErRtT H. C. STEARNS, Ph. D., 


Honorary Associate in Zoology. 


Of the littoral fauna of that long line of coast extending from Point 
Bonita, on the north side of the entrance to San Francisco Bay, to Cape 
Flattery, the southerly point of the entrance to the Strait of Juan de 
Fuea, a stretch of nearly 700 nautical miles, but little is known. The 
general aspect of the coast throughout most of its extent is broken, 
jagged, and rocky, with bold abrupt bluffs, against which in ordinary 
weather the ocean dashes with greater or less violence, and therefore 
unfavorable to the field work of the naturalist. 

There are, however, many reaches of a more inviting character, where 
the rocky shore dips under the sea with so moderate a slope that the 
zone uncovered at extreme low tides is of considerable width, often 
seamed and cut up by narrow furrows and channels, with many shal- 
low pools, and frequently clothed with a heavy growth of bladder weed, 
altogether presenting a tempting challenge to the collector. 

Then there are sandy flats of considerable area, as at Tomales and 
Bodega, and gravelly beaches occur, of moderate extent, with occa- 
sional, sometimes numerous, detached rock masses and bowlders. 

While there are many so-called ports, embarcaderos, or landing 
places between the points above named, especially along the California 
coast, a large proportion, perhaps one-half or more of the coastwise 
settlements indicated on the map, consist of small communities inci- 
dental to the limited local business. At these places it is often the 
case there is no harbor, merely a simple roadstead or anchorage, avail- 
able only in good weather. For the purposes of the collector the 
immediate neighborhood of many of these places is of trifling impor- 
tance. The desirable portions of the coast are generally inaccessible by 
sea and require an outfit for land service, with camp equipage and the 
usual requisites, with ample appliances for shore work. The best time 
of the year is the spring, the months of March, April, and May, before 
the harsh westerly winds begin to sweep in from the sea—usually from 
the first to the middle of June.

Bolinas, Tomales, and Bodega bays, particularly the first and the 
adjacent Duxbury reef, being near San Francisco, have been visited by 
a few collectors, by Colonel Jewett and myself in 1866, and since by 
Raymond, Hemphill, and Wood, and again by the author, but nothing 
like thorough work has been done even at these places, the number 
of species of mollusks usually obtained being from 90 to 100. At 
Bodega, visited by Dr. Newcomb and myself in 1867, some 90 species 
were collected. Mr. Hemphill has collected at Fort Bragg and Hum- 
boldt Bay, at the latter place securing some interesting forms, including 
Paludinella newcombiana, a new species. On the coast of Mendocino 
County, nearly thirty years ago, Mr. Harford found near Big Spanish 
Flat a new Fusus (fF. harfordii). His collection was exceedingly 
meager, most of his time having been devoted to botany. A visit to 
Crescent City made by the author in 1862 was a failure so far as shell 
collecting was concerned, for the beaches and shores in every direction 
were so piled up with driftwood and the refuse of the great flood of the 
previous winter as to be absolutely inaccessible. Some little collecting — 
has been done at Coos and Shoalwater ' bays and at Grays Harbor, on 
the coast of Washington. 

It will be seen from the foregoing that the totality of research 
throughout this great stretch of coast is quite insignificant. The same 
may be said in great measure of the biological investigation of the 
uplands back from and bordering on the shore. — 

The occurrence of Olivella intorta in quantity somewhere along the 
coast in the neighborhood of Trinidad is implied by the large number 
of this rare species contained in a necklace” obtained from the Hoopa 
Indians by Lieutenant Ray. 

Another peculiar form has recently been added to the few that have 
been detected in the region herein reviewed. 


HALIOTIS FULGENS Philippi var. WALALLENSIS Stearns. 


On the coast of Mendocino County, California, in the extreme south- 
west corner, close tothe northerly boundary line of Sonomo County, is an 
embarcadero, or shipping point of the lumber interests of that neighbor- 
hood. Here is situated a small settlement known as Gualala.? The 
coast hereabout is broken and rocky, with bluffs 50 to 100 feet high. 
In the immediate vicinity of this village Mr. J. J. Rivers some years 
ago collected the form here described,* specimens of which are contained 


1It may be well to recall what I have elsewhere mentioned, the planting of Mya 
arenaria in Shoalwater Bay by Captain Simpson, of San Francisco. This was some 
fifteen years ago.

3Gualala, which is the official post-office name of the village, is a localized cor- 
ruption of the Indian Walalla, which latter, I think, should be perpetuated.

XII, January, 1899.

in the U.S. National Museum (Cat. No. 98327) and in the museum of 
the University of California. 

The examples in the U.S. National Museum collection were presented 
to me by Mr. Rivers, and are a part of the original lot. The largest 
adult is of much smaller size than average full-grown examples of the 
ordinary form of H. fulgens. My examination of the entire series col- 
lected by Mr. Rivers suggested the European H. tuberculata of the 
Channel Islands. There is a Japanese species figured in Reeves’s 
Conchologia Iconica, H. planata Sowerby, which it Somewhat resembles. 
As my notes were unfortunately destroyed some years ago, Mr. Dall 
has kindly furnished the following from the U. 8S. National Museum 
examples: 


Shell of an oval form, considerably flattened, and with about two and a half 
whorls; color, dark brick red, with occasional mottlings of pale bluish green; holes, 
four in the young to six in the adult; sculpture of fine, somewhat irregular spiral 
threads, crossed by fine, close, slightly elevated, sharp concentric lamelle, and a 
few small obscure wavelets which radiate obliquely from the apex; nacre rather 
pale, with pink and pale-green reflections, but much less deep in color than the 
typical fulgens. 

This variety differs from the type in its more elongate and flattened form, its con- 
stantly finer, spiral threading, and its paler nacre. The concentric lamellation is 
sometimes undeveloped on the young shells. It has the same number of holes as 
the type. 


The above may be regarded as the extreme northerly expression of 
H. fulgens, which has not heretofore been credited to any part of the 
coast north of Point Concepcion. From that point to Gualalla is an 
immense jimpe about 320 nautical miles, 

Regarding the number of holes in certain species of Haliotis, I find 
the following in my notes: H. fulgens, from Lower California, fifty-six 
show a total of 326 complete and incomplete, an average of six and a 
fraction; one example had 8 and five 7 holes. Of H. rufescens twenty- 
four had 87 complete, fifteen showing 60, and nine 27 holes, an average 
of 33. H.cracherodii, thirty-seven examples gave a total of 236 com- 
plete holes, an average of about 65; one individual. had only 2, two 
had 4, while five had 9, approaching the insular form known.as Cali- 
forniensis Swainson. All of the foregoing were adult shells. 

The “Abalone fishery” on the west coast has been pursued unceas- 
ingly for about thirty-five years. My notebook shows that as long ago 
as the year 1866 no less than 1,697 sacks, each containing from a bushel 
to a bushel and a half, were exported to China. At that time, and for 
many years after, the ‘‘dried meats” only were of commercial value, 
there being but a very limited demand for tle shells. Later the shells 
came into general use for a great variety of purposes, so the fishery has 
been followed more energetically than ever, with the result that in many 
places the supply has been nearly exhausted. In certain localities 
where the principal species, Haliotis rufescens, H. cracherodii, and 
H. fulgens, were abundant they are now comparatively scarce. Recently 


142 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXII. 


the attention of the authorities of some of the seaboard counties having 
been called to the matter, it is likely that before long the fishery will 
be either prohibited for a term of years or in some way regulated by 
law. From the little island of Anacapa in the Santa Barbara chan- 
nel two persons obtained over 2 tons of shells and meats, being their 
second catch within a few months. Fortunately there are numerous | 


places along the coast that are inaccessible, so there is but little danger _ 


of any of the species becoming absolutely extinct. 


ON THE LOWER SILURIAN (TRENTON) FAUNA OF 
BAFFIN LAND. 


By CHARLES SCHUCHERT, 


Assistant Curator, Division of Stratigraphic Paleontology. 


INTRODUCTION. 


In the summer of 1897, a number of men took advantage of the Sev- 
enth Peary Arctic Expedition to cruise in Arctic seas and to hunt and 
fish in Baffin Land. The author had the pleasure of meeting these 
men while on board the steamer Hope, and learned that they intended 
to make a whale-boat trip to the head of Frobisher Bay. As many 
Lower Silurian fossils had been seen by Hall during his exploration of 
this bay, the author requested the Baftin Land party to search for fos- 
sils. On the subsequent return of the steamer Hope from North Green- 
land, it was a great surprise to find that Messrs. J. N. Carpender, R. 
W. Porter, A. V. Shaw, A. H. White, and F. G. Goodridge, had made 
splendid collections of fossils during their stay of but a few hours at 
Silliman’s Fossil Mount, which is at the head of Frobisher Bay. 

These fossils are well preserved, and here, as 1s so often the case in 
Paleozoic faunas, the brachiopod specimens predominate. However, 
unlike other Trenton faunas, the Arctic mollusca usually preserve the 
shell, and this is the more remarkable because all the fossils weather 
out of a bluish clay. The author’s interest in and admiration for these 
well-preserved fossil forms from a rarely visited region was so great 
that he could not resist asking the loan of the various collections for the 
purpose of making them known to paleontologists. Mr. J. N.Carpen- 
der, of New Brunswick, New Jersey, who had the most extensive col- 
lection, with great liberality allowed the author to make a selection 
from these fossils for the U.S. National Museum. From him, there- 
fore, this Museum has received 54 species represented by 113 speci- 
mens. The next largest lots were gathered by Messrs. A. H. White 
and A. V. Shaw, and purchased for the Museum. Mr. F. G. Goodridge 
presented one of the finest trilobites found. Mr. R. W. Porter also 
made a good collection, which he deposited in the American Museum

of Natural History, and these specimens were kindly placed at the 
author’s disposal for study, by Prof. R. P. Whitfield. To these gentle- 
men, therefore, paleontology is indebted for rendering it possible to 
describe one of the best collections of fossils made in Arctic regions. 

With the aid of a camera lucida, Mr. E. O. Ulrich, of Newport, 
Kentucky, made the figures, which are accurate representations of the 
species. The author is further indebted to him for paleontological 
assistance, and his various notes are incorporated in this paper in 
their proper places. 


DESCRIPTION OF LOCALITIES. 


Frobisher Bay.—Previous to 1897, all that was known of the geology 
of Frobisher Bay was included in a few incidental notes by Charles 
Francis Hall.' His collections were partly studied by Mr. R. P. 
Stevens? and Prof. B. K. Emerson.’ 

During the months of August and September, 1861, Hall, in com- 
pany with Innuit men, women, and children, explored, by means of 
whale boats, the greater part of Frobisher Bay, which up to that time 
was believed by civilized man to be astrait. On this trip he was also 
greatly rejoiced to find unmistakable evidence of Frobisher’s visit of 
1556-57. The book cited is interesting reading, and from it are taken 
the following notes regarding the geology of this Bay. 

Jones Cape.—Hall ‘“‘ascended a mountain in the rear of our encamp- 
ment. * * * On my way I observed a considerable quantity of the 
stone I had noticed upon Iron Island, and I also saw many small pieces 
of limestone on the very summit about a thousand feet above the level 
of the sea.” + 

This may be the locality which furnished the fossils from the Utica 
stage, described by Professor Emerson and listed beyond. 

Cape Stevens.—This locality is nearly 100 miles farther inland than 
Cape Jones, and here Hall on the top of a mountain “found numerous 
shells and fossils, some of which |he] brought away.” 

This may be the locality furnishing the Trenton fossils described by 
Professor Emerson and listed beyond. 

Sillimaw’s Fossil Mount.—At this place fossils were first brought to 
Hall by the natives. 

At my left, across the river, was aridge of white, which I afterward named Silli- 
man’s Fossil Mount (thus named after Benjamin Silliman, jr., of New Haven, Con- 


necticut. This fossil mount is on the west side of the termination of Frobisher Bay. 
It is in latitude 63° 44’, longitude 68° 56’), and behind it the unbroken front of a line

of mountains extending northwesterly to the opening which I have called the Great 
Gateway.! * * * 

I visited that phenomenon; I mounted it, and went around italso. Itis amount 
of marine fossils in limestone, half a mile long, and over a hundred feet high [840 
feet aneroid, according to Porter]. * * * The débris of the fossils begins at or 
near the top of the mount, falling at such an angle as broken stone from a mountain 
always make, an inclination of about 40°. Above the talus, or heap of broken stones, 
is a mass of fossils in limestone, strata-like. A smaller mount of the same char- 
acter is close by, but all 
in débris. It seems to fe 
have been divided from 
the main mount by the 
rushing down of waters : 
from the mountains he- 2 oS 
hind. A small stream 
comes down the moun- 
tains, passes along, and 
finally makes its way out 
between the two fossil 
mounts. This is also in- 
dicated in the course of 
this stream, as an acre 
or more of the plain is 
covered several feet in 
depth with the washed- 
down débris of fossils.

covered with boulders 
and grass. Even when close to the small mouat it looks like sand, but on examina- 
tion it is fine broken limestoné and fossils.” 


Mr. R. W. Porter, who visited Silliman’s Fossil Mount in August, 
1897, described it to the writer as follows: 


ON BOARD 8. 8. HOPE, 


September 18, 1897. 
CHARLES SCHUCHERT, Esq. 


My Dear Sir: In accordance with your request, I take pleasure in handing to 
you the following notes on Silliman’s Fossil Mount (Hall’s) of Frobisher Bay, Baffin 
Land. They are very meager—the results of only a few hours’ visit to this forma- 
tion, as J had intended to give the place a more thorough search next year. 

Silliman’s Fossil Mount lies at the head of Frobisher Bay, some 3 miles south of the 
Jordan River and about 1 mile from tide water. It lies close against the mountains 
of Meta Incognita [apparently unconformably], is about 1,000 yards long and 340 feet 
high (aneroid; not 100 feet, as given by Hall), general (lirection northwest and south- 
east. The fossils were taken from the talus slopes, the bed of the brook flowing 
at the base of the mount, in the limestone near the summit, and on the top itself. 

At its northern end there is a smaller mount of lesser height. The mount forms 
a striking feature of the landscape, and is composed of limestone, disintegrated to 
such an extent that the talus reaches nearly to the summit, which is very flat and 
composed of the ledge itself. This limestone ledge of nearly horizontal beds out-

crops all around the summit with vertical sides 10 to 20 feet high. The summit or 
table top is covered with moss and grass and several large bowlders of glacial origin. 
At its southeastern extremity it is joined to the range of mountains running par- 
allel to the mount and rising to altitudes of from 500 to 800 feet. Between the 
mount and neighboring mountain side flows a good-sized brook, flowing northwardly 
and out into the valley between the 
greater and lesser mounts. 

This brook has probably caused the 
separation of these two elevations, 
and has carried a quantity of clay 
and limestone out into the valley for 
several hundred yards. 

A close scrutiny of the adjacent 
mountain range revealed no limestone 
formation on its side. The rock of this 
range is a dark mica-schist, the dips 
making an angle of about 30° with the 
horizon. Its surface in many places 
shows the marks of glaciation (one 
moraine lying against the northern 
side of the smaller mount), but for the 
most part the parent ledge is hidden 
under a quantity of its own rock 
broken up by frost action. 

‘I found a great number of limestone 
bowlders, erratics, scattered through 
the valley of the Jordan River and on

know that the natives told me that 

these same formations containing fossils existed in several localities in the lake 
region of the interior. 

Very truly, yours, 


RUSSELL W. PORTER. 


Region west and northwest of Frobisher Bay.—From Mr. Porter’s 
account of Silliman’s Fossil Mount, it is evident that similar Lower 
Silurian strata occur in the lake region of the interior of Baffin Land. 

Mr. EK. M. Kindle! reports that Missionary Peck obtained from Lake 
Kennedy, which lies northwest of the head of Cumberland Sound, the 
following drift fossils: 

Zaphrentis sp.? [probably Streptelasma corniculum|. 

Halysites catenulatus |probably var. gracilis Hall]. 

Maclurea magna? [probably Maclurina manitobensis]. 

Endoceras proteiforme. 

With the fauna of Silliman’s Fossil Mount as a guide, it is probable 
that no horizon other than the Trenton is indicated by the species cited. 

Dr. Robert Bell? reports that—

among which Receptaculites Oweni was easily distinguished. Shells and bryozoa, 
belonging to moderately deep-water species, were found on the same pans. The 
limestone fragments, just mentioned, would point to the occurrence of Silurian rocks 
on or near the great bays in the western part of the north shore of the straits, where 
the land is said to be low [see also the description of Akpatok Island]. Dr. Franz 
Boas of Berlin [now of New York] has recorded the existence of these rocks in the 
interior of Baffin Land, about 2 degrees of latitude north of this region, He says:! 
“Through the occurrence of the Silurian rocks in the Nettilling (Lake) (— Lake 
Kennedy), the discovery of the same formation at the upper end of Frobisher Bay 
increases in value. We must now suppose that the Silurian limestones, which appear 
at Prince Ruperts Inlet, extend from there to Frobisher Bay, and overlie the granites 
and gneisses of Baffins Bay aud Davis Strait. We will not be far astray if we con- 
nect this extensive Silurian district with the limestones which occur to the south of 
Igluling; and which form the flat eastern half of Melville Peninsula. Southward 
from Nettilling, these rocks rise in low hill ranges.” 


Farther to the north, great areas of Upper Silurian rocks occur, 
yielding characteristic fossils of this age. In association with this 
fauna also occur species of Lower Silurian age. Two of these are. 
Receptaculites arcticus Etheridge, and R. occidentalis Salter. The latter 
may be the same as R. oweni of this paper, a species closely related to 
R. occidentalis. One or both of these species are found associated with 
a typical Upper Silurian fauna at Cape Louis Napoleon (latitude 79° 
38/ north), and Cape Frazer (latitude 79° 45/ north). Maclurea arctica 
Haughton, WM. logani Salter, and M. magna Lesueur, are also identified 
as occurring in this region in Upper Silurian faunas. Such localities 
are Fury Point (latitude 72° 50’ north, longitude 92° west), Depot Bay 
(latitude 72° north, longitude 94° west), Cape Hilgard (latitude 79° 
41’ north), and Bessels Bay (latitude 81° 6’). Maclurea arctica with 
Actinoceras crebriseptum Hall and Receptaculites neptunt Defrance (prob- 
ably = R. oweni) are found with Upper Silurian fossils on the west 
coast of King Williams Island. Maclurea, or Maclurina, is a genus 
restricted to the Lower Silurian, and the same is true of Actinoceras 
crebriseptum. On the other hand, Etheridge has described as Helico- 
toma nuresii, a similar shell from the Upper Silurian of Offley Island 
(latitude 81° 16’ north) and with this the author has identified a speci- 
men in the U.S. National Museum collected by Dr. E. Bessels at Polaris 
Bay (latitude 81° 38’ north). The preservation of these shells, however, 
is such that any identification will have little value. 

The foregoing facts can be interpreted in various ways: 

First, Arctic collections of fossils are usually made by explorers who 
pick up loose fossils, some of which may have been carried by the ice 
considerable distances. In this way, specimens from several horizons 
become mixed. The author, however, does not believe that this is gen- 
erally the case here, since the apparant mixtures occur in seven local- 
ities distributed between latitudes 72° to 81° 6’ north. 

Secondly, the identifications are not uniform, and this is particularly 
true of the specimens ot Maclurea. For the present, therefore, it will

148 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXII. I 


be necessary to eliminate such identifications as horizon markers from ; 
the Upper Silurian local faune. 

Thirdly, Receptaculites arcticus,! R. occidentalis, and R. oweni are good 
Lower Silurian horizon markers and are easily identified. Therefore 
the writer accepts the presence of these forms as indicative of Lower 
Silurian rocks. Such localities are Cape Louis Napoleon, Cape Frazer, 
and the west coast of King Williams Island. 

From this evidence, it appears that to the north of Baffin Land wher 
areas of Trenton strata occur, and likewise that at Cape Louis Napoleon, 
Cape Frazer, and on the west coast of King Williams Island, they 
underlie the Upper Silurian beds. Probably, it is this occurrence 
rather than the transportation by ice, which has led to the aes of 
the faunas. 

Akpatok Island.—The Trenton of Frobisher Bay and Lake Kennedy 
apparently continues southward to Hudson Strait, where, in the vicinity 
of Big Island, Receptaculites owent was found by Dr. Bell on pan ice, as 
described above. Another Trenton limestone area occurs more to the 
east, and near the south shore of Hudson Strait, on Akpatok Island, in 
Ungava Bay. Here Dr. Bell? obtained 90 fossils of Trenton age. He 
writes: 


The portion of the island which I saw [northern end to middle of east side] con- 
sists of unaltered gray limestone in horizontal beds, and it presents a perpendicular 
wall 400 to 500 feet high all along. This sea wall is clear cut and the beds appear 
thick and solid, but wherever their edges have been long exposed to the weather or 
in the hillsides and ravines of the interior, they split up into thinner layers. Some 
fragments observed in one place had the appearance of lithographic stone. * * * 
This formation must here have a thickness of 900 feet above sea level, and there is 
possibly a great additional thickness of Cambro-Silurian rocks beneath the sea level. 


EXTENT OF THE ARCTIC TRENTON. 


From the foregoing description of localities, it appears that Middle 
Lower Silurian horizons are very extensive in eastern Arctic America. 
Such are known in places on either side of Hudson Strait, Frobisher 
Bay, the interior of Baffin Land, and to the north of this land at vari- 
ous localities between latitudes 79° and 80° north. As far as known, 
these strata unconformably overlie very ancient crystalline rocks and 
are in turn overlain by Upper Silurian beds of Niagara or Wenlock age. 
Lower Cambrian rocks are found in southern Labrador, but in the 
region of Baftin Land such are not known to be present. Here, then, 
there seems to be a complete break from the Laurentian to the Tren- 
ton, followed by another break paleontogically, in the absence of the 
Cincinnatian beds, and probably the lower horizons of the Upper 
Silurian. The Lower Silurian fossils of this area indicate nothing older 
than the por Trenton of New York and the Galena of Wisconsin and 


iPhe fans of ani species are in adhe British Mnccnn and Dr. Hinde in his work 
on the Receptaculitide (Quart. Jour. Geol. Soc., London, November, 1884, p. 845) 
gives the horizon as Lower Silurian.

- Minnesota, and nothing younger than the Utica stage of the United 
States. The thickness of these beds is not less than 900 feet and prob- 
ably exceeds this. 

This summary is based on information known to the author, and, 
while the evidence is meager, the essential geological age and the 
sequence of the rocks of Baftin Land seem to be established. 


PALEONTOLOGY. 


Hall's collections.—The few fossils collected at Silliman’s Fossil Mount 
and brought to America by Mr. Hall were identified by R. P. Stevens! 
for the New York Lyceum of Natural History, as follows: 

Maclurea magna Leseuer [probably Maclurina manitobensis]. 

Endoceras proteiforme Hall? [—Cameroceras proteiforme]. 

Orthoceras (badly worn specimens). 

Heliolites (new species). 

Heliolites (new species). 

Halysites catenulata. : 

Receptaculites (new species) [=?R. oweni of this paper]. 

There is apparently nothing in this list but what was again discov- 
ered in 1897. Mr. Stevens writes that ‘the fossils, without doubt, are 
all Lower Silurian,” and on the basis of the Maclurea magna “would 
place the limestone containing it on the horizon of the Chazy limestone 
of New York.” However, it does not appear that this writer announced 
any particular age beyond Lower Silurian for the rocks comprised in 
‘Silliman’s Fossil Mount.? 

_Another lot of fossils collected by Hall on his first expedition to 
Frobisher Bay was given to Amherst College, and forms the basis of 
Prof. B. K. Emerson’s report ‘‘On the Geology of Frobisher Bay and 
Field Bay.” In this lot, there is apparently nothing from Silliman’s 
Fossil Mount, but Utica and Trenton fossils are present from localities 
more to the eastward and from the north shore of Frobisher Bay. 
These are:

the other fossils reported upon in Mr. Stevens’s article quoted.” See ‘On the Geol-

Arctic Expedition made by Charles F. Hall,” edited by Prof. J. E. Nourse, Washing-

The Trenton horizon may be the same as that of Silliman’s Fossil 
Mount. In any event, the foregoing lists indicate horizons intimately 
connected, and it is probable that all the fossiliferous strata at the head 
of Frobisher Bay are of Trenton and Utica age. 

Akpatok Island.—The fossils collected by Dr. Bell on Akpatok Island 
have been studied by Professor Whiteaves,' with the following results: 

The species indicate the Trenton limestone, and ‘are remarkably 
similar to the fossils of the Trenton formation of the Red River Valley 
in Manitoba.” ‘Eleven had previously been found in the Manitoba 
Trenton, and nine are species that are common at East Selkirk and 
Lower Fort Garry.” This fauna also connects directly with that of 
Silliman’s Fossil Mount. 

The following is a list of the species:

Age of Silliman’s Fossil Mount.—From Mr. Porter’s description, it 
will be seen that the fossils recently collected at Silliman’s Fossil 
Mount are from various horizons, and yet there is nothing to indicate 
the presence of more than one fauna. The foregoing list shows that at 
present there are 72 species known from this locality, and of these 28 
are restricted to it. There are, therefore, 54 species which are common 
to other localities, a goodly number with which to make safe correla- 
tions. Of these 54 species, 41, or 57 per cent of the known fauna, are 


also found in the region of Minnesota, Wisconsin, and Iowa, while 17 — 


are known to occur in New York and Ottawa. 

On comparing the 54 widely distributed species with those from 
definite stages in Minnesota, it is seen that 10 are also found in Birds- 
eye (= Lowville), 17 in the Black River, 38, or about 70 per cent, in the 
Galena, the direct equivalent of the New York Trenton, and 11 in the 
Cincinnatian group. 

From these figures it is evident that the stage of Silliman’s Fossil 
Mount belongs in the Galena, and that the fauna is more intimately 
related to that of the Minnesota region than to the Trenton of New 
York. When the New York Trenton fauna is restudied in the light of 
recent researches in Minnesota,' however, it will be shown that the 
two faunas have more in common than now appears. On the other 
hand, the lithological similarities of the Minnesota Galena and Silli- 
man’s Fossil Mount—light-colored shales predominating in both areas— 
may explain in large measure the close identity of these widely sepa- 
rated faunas. 

This little fauna likewise brings out the fact that the corals, brachi- 
opods, gastropods, and the trilobites are slow in their evolutional 
change, and the species can therefore spread over very great areas, 
while the cephalopods, and particularly the pelecypods, are more sen- 
sitive to change, and are thus restricted to localities.

circumference, making the species originally not less than 12 inches 
over all. This is about the usual size for the larger specimens of R. 
oweni in Minnesota, although examples have been seen 20 inches in 
diameter. 

Etheridge has described FR. arcticus from Cape Frazer and Cape Louis 
Napoleon in Grinnell Land. This is also a large disk-shaped species, 
similar in growth to R. owent, but the walls are usually twice as thick, 
and the transverse tubes are much larger and fewer in a given space 
than in the species last named.

PLASMOPORA LAMBII, new species. 


This species begins growth on some small foreign object, and expands 
to a diameter exceeding 12 em. by 7 em. in height. Beyond the place 
of attachment the lower surface is irregularly concave and covered by 
a thin epitheca. The upper surface is in form depressed hemispheric 
to conical. Corallites from 1 to 1.75 mm. in diameter, commonly about 
1.25 mm., circular, and separated from one another from 0.5 to 1.25 mm. 
Septa not prominent, and where the original surface is well preserved 
not easily distinguishable from the radial striations, or granular sur- 
face, of the tubular area. Corallites with very closely adjoining tabulz, 
which are generally decidedly vesicular, but in places they are flat. In 
longitudinal sections there are from two to five tubules between neigh- 
boring corallites; the tabulz are convex, generally giving the inter-cor- 
allite space a decided vesicular structure. 

The general vesicular condition of the tabule in both the tubules and 
corallites distinguishes P. lambii. This feature was pointed out by Mr. 
Lawrence M. Lambe of the Canadian Geological Survey, and the writer 
takes pleasure in connecting his name with this new species in appre- 
ciation of his excellent work on the corals of Canada.

CALAPCCIA CANADENSIS Billings. 
For synonymy see Lambe, Geol. Surv. Canada, Cont. to Canadian Pal., IV, 1859,

Of this species, there is a small, depressed, hemispheric specimen in 
which the corallites are in contact, and therefore there is little inter- 
zooecial vesicular tissue. The hexagonal, nearly uniform corallites are 
from 3 to4 mm. in width, and each has from 18 to 20 septa. 

The above identification is confirmed by Mr. Lawrence M. Lambe.

POROCRINUS SHAW/I, new species.

This species is most nearly related to P. smitht Grant,! as far as the 
shape of the dorsal cup, elevation of the costa, and form of the plates 
are concerned. It differs, however, from all American species in that 
the circular pore-rhomb spaces are larger. This is particularly true of 
the lowest series, which occupy nearly the entire basal plates besides 
portions of two adjoining subradials. The rhombs are also very large 
in the interradial areas on each side of the arm bases. 

The ambulacral grooves are narrow and short, and within the shallow 
vestibule terminate abruptly below into the body cavity. The margin 
bordering the large, central, circular opening is somewhat notched at 
each ambulacral groove, giving the impression that there may have 
been communication between the oral opening and each ambulacral 
groove. The smaller ventral plates are not preserved in this specimen, 
which is the only one known. 

Named for Mr. A. V. Shaw, of Boston, Massachusetts, who was one

But a single specimen of this species has been noted, and this was 
attached to an Orthoceras. It has the general aspects of L. affinis in 
the pentagonal column, form of body, slight convexity, number of plates, 
and the general irregularity of these, both in form and arrangement. 

The genus Lichenocrinus has not been previously recorded from rocks 
below the Utica. In the Cincinnatian group specimens are often abun- 
dant where L. affinis occurs in the upper third or Richmond stage.

The Arctic examples are large and robust, and agree rather with speci- 
mens from Watertown, New York, than with those from Minnesota, 
which are somewhat smaller. The species is often confounded with 
Orthis (Hebertella) borealis, but can be easily distinguished by the 
almost entire absence of fold and sinus. When these are present, how- 
ever, they are found to occupy a position the reverse of that seen in the 
latter species.

This species, which is common in the Galena or Trenton stage of 
Minnesota, is also abundant at the Frobisher Bay locality. As in Min- 
nesota, it is here also a very variable species. However, among the 
Arctic specimens this variation tends toward the equalization and 
increase of the number of plications, while in Minnesota, bundling of 
the plications accompanied by the development of a conspicuous dorsal 
sinus, is the chief trend of variation. The specimens having the last- 
named characters were given the varietal name germana. On the same . 
ground it may be advisable to name the Arctic variation—those with 
the more numerous and equal plications, and an obsolete or nearly obso- 
lete dorsal-sinus variety—arctica.

The common Rhynchonella from the Birdseye or Lowville and Black 
River stages, which is usually identified as RK. increbescens Hall, is 
always devoid of the concentric lamell so characteristic of A. incre- 
bescens= R. inequiralvis of the Trenton stage. Occasional specimens 
occur with a few of the lamelle near the anterior margin, but gen- 
erally the shell is devoid of these, their places being occupied by very 
fine, wavy, concentric lines. In higher beds, these fine lines develop 
into stronger and more extended lamelle, which find their greatest 
development in Rhynchotrema perlamellosum of the upper or Richmond 
stage of the Cincinnatian group. 


No. 1192. TRENTON FAUNA OF BAFFIN LAND—SCHUCHERT. 159 


The form of R.minnesotensis is quite variable and can not be of much 
aid in distinguishing this shell from A. inequivalvis. The two are often 
found associated in the same beds, and it is then difficult to identify 
them correctly. This fact led Winchell and Schuchert, in 1893, to regard 
both as belonging to one species, Rk. inequivalvis. 

Locality and formation.—In the Lowville and particularly in the 
Black River stages of the Trenton in Minnesota and Wisconsin, Lex- 
ington, Kentucky, and in the Cincinnatian group at Savannah, Illinois. 
This species and R. inwquivalvis subtrigonalis are unknown at Silli-

This species was first described by Castelnau, who obtained his spec- 
imens from the “magnesian limestone” of Drummonds Island. His 
figures show the characteristic concentric lamellx which are almost 
always present on these shells coming from the Trenton, and this 
feature distinguishes them from those found in the Lowville and 
Black River stages. Hall subsequently described this shell as Atrypa 
increbescens, but it is now generally known as Rhynchonella increbescens. 
The species is a characteristic form of the Trenton, while in the Cin- 
cinnatian group its descendant FR. capax attains large size, often great 
rotundity, with marked concentric lamelle. The lamellar develop- 
ment finds its extreme in R. perlamellosum. 

RK. inequivalvis is abundant at Silliman’s Fossil Mount, the concen- 
tric lamellz being also strongly developed in the specimens found.

There are two examples of this species, and these appear to agree 
best with Minnesota specimens of C. suwbnasuta. They were sent to 
Mr. E. O. Ulrich for direct comparison with his types. He writes: 

You can not be far wrong if you identify these specimens with C. subnasuta. Still, — 
there is some doubt as to their identity. The Arctic specimens are larger than the 
types, and relatively a little more elongate, while the basal outline is scarcely as 
convex, and the umbones not so full and evenly rounded. Finally, the smaller end, 
which I am now somewhat inclined to regard as the anterior, is relatively wider in 
your shells. I may add that the larger specimen indicates a thinner hinge plate 
than in the types, so that, after all, these specimens may belong to a distinct species. 
Typical C. subnasuta occur in the Trenton of Manitoba.

CTENODONTA CARPENDERI, new species. 


(Plate XIII, figs. 1-3.) 


This is the most abundant pelecypod from Silliman’s Fossil Mount 
and appears to be closely related to C. cuneiformis Ulrich.' It dif- 
fers, however, in various details, particularly in always being consid- 
erably larger. C. carpenderi has also the general aspect of small 
specimens of O. nasuta, but differs in the straight hinge line, especially 
that of the posterior end, which terminates abruptly into the regularly 
convex outline of this portion of the shell. 

Mr. E. O. Ulrich, to whom several examples were sent, wrote as 
follows: 

These specimens are closely related to OC. cuneiformis Ulrich. The types of that 
species are much smaller, with the narrower end relatively shorter and the constric- 
tion more distinct. Good specific differences are found in the postcardinal region 
(i. e., assuming that the wider end is posterior). Here the Arctic species is more 
impressed, causing the umbonal ridge to be much more prominent, the postcardinal 
slopes wider and concave instead of flat. Just behind the beaks there is a triangu- 
lar shaped area (ligamental probably) which is wanting in C. cuneiformis. 

Named after Mr. J. N. Carpender, of New Brunswick, New Jersey,

CTENODONTA BAFFINENSIS, new species (Ulrich). 
(Plate XIII, figs. 7-10.) 


There is but a single example of this species present, and this was 
provisionally identified as C. scofieldi Ulrich.’ The author of the species 
writes that, while it has the general aspect of C. scofieldi, it is neverthe- 
less sufficiently distinct to be recognized as new. Mr. Ulrich has made 
the following comparisons: 

At first sight this is extremely like C. scofieldi, but on closer inspection, and par- 
ticularly when compared with the types of that species, certain peculiarities become 
so prominent that I wonder that they were not observed at once. The first of these 
is a depression, or rather widening furrow, extending vertically from the beaks across 
the valves. This is sufficient to cause a straightening, even a slight concavity, in 
the ventral outline. The outline of the valves differs further in the postventral 
(wider) region being more prominent and more narrowly rounded here. In a car- 
dinal view the species agrees best with C. scofieldi, but in a lateral view the outline 
corresponds better with C. medialis and C. nitida Ulrich. The contour of the valves, 
however, shows it to be a distinct form, the mesial depression possibly indicating 
relations to species of the type C. carinata Ulrich. C. scofieldi also has no radiating 
lines; the concentric lines are equally as delicate. ; 


Collector.—R. W. Porter. The type is in the American Museum of 
Natural History. 


CTENODONTA FROBISHERENSIS, new species. 
(Plate XIII, figs. 11-14.) 


Of this little shell there are two well-preserved specimens, which 
appear to be distinct from all other Ordovician Ctenodontas. Probably 
the species most nearly related is C. albertina Ulrich,’ from which it 
differs in having the beaks more centrally situated, the valves shallower, 
and in being less drawn out anteriorly. At first this form was thought 
to be most closely related to C. oviformis Ulrich,® but the author of 
the latter species writes that the Arctic shell ‘“‘has different propor- 
tions” and that it represents a new species. C. oviformis is less high, 
has narrowly rounded ends, and the beaks are situated nearer the mid- 
length. Its rounded-ovate form distinguishes it from the other Fro- 
bisher Bay species, all of which are nasute forms.

WHITEAVESIA SYMMETRICUS, new species (Ulrich). 
(Plate XIII, figs. 15-17.) 


This little shell was thought by the writer to be probably identical 
with Crytodonta affinis var. fillmorensis Ulrich,' and for confirmation of 
this opinion sent the specimen to Mr. Ulrich. He, however, refers it to 
the genus Whiteavesia of the family Modiolopside. As his notes are 
detailed, they are given at length. 

Remains of the black ornament-bearing epidermis prove the specimen to belong 
to the Modiolopsidx. It is a new species, with an anterior end reminding of Modio- 
lopsis arguta, while the rest of the outline and general aspect is more nearly hke M/. 
similis. It is also like MW. obsoleta, but it is too high posteriorly. It is, however, 
not a true Modiolopsis, the umbones being too prominent and full, the ventral outline 


convex, and the anterior muscular scars scarcely distinguishable in the cast. These~ 


characters make it a Whiteavesia, and it does not seem to be closely related to any of 
the described species of that genus. The rather uniform convexity of the valves is 
peculiar to this species.

Mr. Ulrich has kindly made the following notes on this species: 


Have compared this with every Cyrtodonta known to me without finding one 
with which it is identical. Ina general way it reminds of C. affinis, C. parva, and 
C. halli,? but am satisfied it is not closely related with any of that group of species. 
Its true affinities seem to be with C. subcarinata Billings, but is readily distinguished 
by its shorter form and much broader posterior. From C. huronensis Billings,’ which 
I regard as another close ally (also C. billingsi Ulrich ”), it differs not only in size but 
in its greater convexity and much better defined antero-median suleus. The speci- 
men is preserved in part as a cast of the interior, and I am therefore inclined to 
doubt that the sulcus is as strongly defined on the exterior of the shell as shown on 
the specimen.

what less gibbous, particularly in the umbones, the beaks also coming closer, i.e., 
they are almost in contact, while they are rather widely separated and less inourtved

In the absence of evidence concerning the hinge, the generic position of the shell 
is necessarily doubtful. Therefore, although admitting provisionally that it is 
closely allied to Cyrtodonta gibbera, I am not at all satisfied that it will not turn out 
to be a Vanuxemia near J’. abrupta.

SEELYA(?) (PLETHOSPIRA?) ULRICHI, new species. 
(Plate XII, figs. 9, 10.) 


This interesting little shell has many of the characteristics of S. 
ventricosa Ulrich,! from the Calciferous (Beekmantown) stage. It is, 
however, a much smaller shell, and differs from all known species of 
Seelya in having the revolving bands nearly obsolete. 

There are four of these shells, which were sent to Mr. Ulrich for iden- 
tification. He writes: 

The specimens are casts of the interior, and the revolving peripheral furrows 
probably have nothing to do with the revolving sculpture of the true Seelya. Simi- 
lar furrows occur in good casts of Lophospira bowdeni and other Pleurotomariide. 
The band, I believe, was of the flat or concave type, as in Seelya, Plethospira, and 


Hormotoma, but, as it was evidently close to the suture and partly covered by same, 
it is too low on the whorls to be in strict accordance with these genera. 


Oollector.—A. H. White. Cat. No. 28187, U.S.N.M. The American

Of this species there is a single excellent specimen, which the writer 
at first labeled Liospira angulata Ulrich, variety. However, when 
Ulrich compared the Arctic example with the type species he con- 
cluded it to be Helicotoma larvata Salter. He has kindly made the 
following notes on this specimen: 

This species resembles Liospira mundula, L. angulata, and other species of that 
section of this genus very greatly, and it may be, as I once thought, truly referable to 
Liospira. Excepting that the Arctic specimen is small, it is the best preserved yet 
seen byme. Still I am unable to settle the difficulty. Whatever light it casts upon 
the problem is in favor of retaining the species under Helicotoma. 

In Canada this is a Black River species.

Three examples of this species are present, only one of which is well

binst and T. saltert. He writes as follows: 


These specimens possibly indicate a form intermediate between 7. (H.) similis and 
T. (E.) robbinsi Ulrich and Scofield. The upper whorls of the best specimen agree 
rather closely with the former, while the last whorl, with its relatively narrow 
peripheral band, is more in accordance with the latter species. It is to be borne in 
mind, however, that it is only the shell-less portion of the specimen that agree 
with T. (£,) similis, the opposite side of the same whorls showing no trace of the 
ridge near the suture, which is strongly developed and is characteristic of 7. similis.

I regard it as related to some of the Gotland shells referred to Trochus by Lind- 
strém, but as the specimen retains no trace of the sculpture-bearing layer of the shell 
it can not be compared satisfactorily with described species. Lindstrém’s 7. den-

This little shell is clearly related to the previous species, having many 
of its characters. It differs, however, in its smaller growth, greater 
cenrvature, and most decidedly in the very rapid increase of the cone. 
The greater curvature is due to the rapid increase in depth of the air 
chamber toward the ventral side, where near the living chamber it is

often three times the depth on the dorsal side. The siphuncle is very 
small, almost in contact with the ventral wall, and swells but little 
between the septa. 

Professor Whiteaves, who saw the type, states that among the frag- 
ments of Cyrtoceras from Manitoba “are some apparently like (@. cor-

This small species of Cyrtoceras has the general aspect of C. manito- 
bense, and for a time was regarded as the young of that species, yet a 
comparison shows that C. baffinensis has a somewhat smaller apical 
angle. The diagnostic feature, however, is in the depth of the air 
chambers. These are much more shallow and do not increase in depth 
with growth nearly as rapidly as in C. manitobense, there being twenty- 
two of these in 25 mm., while in the latter species at a similar stage of 
growth there are about sixteen.

Oncoceras exiguum CLARKE, Geol. Minn., III, Pt. 2, 1897, p. 798, pl. Lvim, 
figs. 10, 11. 

In this collection there are five specimens of this species, three of 
which preserve more or less of the body chamber, and permit a recon- 
struction of the form of the shell. The body chamber was not less than 
15 mm. in length and the entire shell not less than 58 mm. Billings gives 
the probable length as about 50 mm., which is very close to the protrae- 
tion based on Arctic material. Clarke writes that the Minnesota speci- 
mens probably did not exceed 30 mm., but as his specimens are very 
small fragments, this estimate is probably short of the actual length. 
The first twelve septa back of the living chamber occupy 22 mm., and in 
another specimen there are nine in 19 mm. The depth of the air 
chambers decreases very little toward the apex, the average being a 
little less than 2 mm. down to where the shell has a diameter of 3.5 mm. 

Specimens from shale are usually compressed, and this is the condi- 
tion of the Arctic material, but the shell was circular in outline, with 
a very small central siphuncle. 

This species is related to Oncoceras mumieformis Whitfield, which 
Clarke referred to Clinoceras. The Arctic material shows the shell to 
be gently arcuate and to possess the other generic characters of Clino- 
ceras. Billings’s species should be referred to Maschke’s genus. ~*

ONCOCERAS ARCTICUM, new species. 
(Plate XIV, figs. 4-7.) 


As shown by the figures, this species differs from all other American 
Oncoceras in the great antero-posterior curvature of the ventral side of 
the shell. This is caused by the rapidly increasing depth of the air 
chambers toward the ventral side, where they are about twice the 
depth of the dorsum. Siphuncle small, slightly constricted at each 
septum, and closely adjoining the ventral wall except immediately 
beneath the living chamber, where it is slightly deflected dorsally. 
Venter more broadly rounded than the dorsum. Living chamber large, 
with the sides slightly constricted, not less than 24 mm. deep, 33 mm. 
dorso-ventrally, and 24 mm. transversely. The cast is smooth and pre- 
serves no markings of the exterior. 

Cyrtoceras cornulum was first thought to be the young stage of 
Oncoceras arcticum, but its section is more elongate-oval, with the dorsal 
side more rounded, the reverse being true in the latter species. The 
chambers also are deeper on the ventral side, the ventral curvature is 
less strong, and the shell thicker, with longitudinal plications. 

Collector.—J. N. Carpender. Cat. No. 28196, U.S.N.M. 


ONCOCERAS TUMIDUM, new species. 
(Plate XIV, figs. 1-3.) 


This species is much larger than any other in the Trenton of the 
United States, although much smaller than O. magnum, the giant of 
the genus, which is found at East Selkirk, in Manitoba. The present 
form seems to be most closely related to O. gibbosum Whiteaves! 
(=0. whiteavesi Miller), but has not the numuloidal siphuncle of that 
species, nor the sigmoid outline of the septa on the dorsum. The 
living chamber, also, is shallower, being about 28 mm. deep. The con- 
striction of O. tumidum recalls that seen in Poterioceras or Gomphoceras, 
but unlike these shells is not bilaterally symmetrical. The specimen 
preserves but 6 septa and the living chamber, and throughout all 
there is a rapid regular convergence toward the anterior end. Dorsal 
end of shell broadly rounded, with the ventral side somewhat acutely 
rounded. The 5 air chambers are dorsally 13 mm. deep and ventrally 
25 mm. The siphuncle is small and situated about 6 mm. inside the 
ventral wall. Septa regularly but deeply concave. 

The type specimen was sent to Professor Whiteaves for comparison 
with O. whiteavest Miller. He reports that Oncoceras tumidum is “very 
much like O. whiteavesi Miller (=O. gibbosum Whiteaves, not Hall) 
in lateral contour, but in your specimen the body chamber does not 
seem to narrow so abruptly as it always does in O. whiteavesi, and shows 
no sign of any constriction at the aperture.”

There is a poor specimen of this genus from the Frobisher Bay 
locality. It was thought to be a small specimen of P. nobile, and was 
therefore sent to Professor Whiteaves'! for comparison. He, however, 
writes: 


We have nothing exactly like this. It is very similar in shape to P. nobile, except 
that the latter is somewhat compressed and yours is not. The difference in size 
between your specimen and ours is, of course, enormous. Your shell also is not very 
unlike the so-called Gomphoceras eximium Billings, but that species is ovate in trans- 
verse section, possibly from lateral pressure. Your specimen is, I should think, most 
likely a Poterioceras, but too imperfect to show its specific characters or affinities.

broadly rounded or subquadrate, with a centrai, short projection. The 
occipital ring is also much wider, and is strongly elevated medio- 
posteriorly into an obtuse apex. Of thoracic segments, nine are pre- 
served in these specimens. 

The pygidium is likewise less triangular than in D.(P.)eboraceus, and 
while there are ten or eleven annulations on the axis, there are not 
more than five pleure. These are well developed anteriorly, becoming 
rapidly more and more obsolete.

There are three examples of this species in the collection, none of 
which are entire, but all agree well with New York specimens. The 
species did not here attain quite the large size of New York specimens, 
but one glabella shows a growth about two-thirds of the largest from 
the latter locality.

SUMMARY. 


The only Lower Silurian horizons known in northeastern Arctic 
America are of Trenton and Utica age. The latter zone appears only 
on the north shore of Frobisher Bay, but the Trenton is found in 
various places from the north shore of Hudson Strait to latitude 81° 
north. The Lower Silurian is thickest on Akpatok Island, where it is 
from 400 to 500 feet in depth. Dr. Bell, however, estimates the entire 
thickness of these strata in this region to be not less than 900 feet. 

In Baffin Land, and apparently elsewhere in Arctic America, the 
Lower Silurian strata rests unconformably on old erystalline rocks. 
To the north of Baffin Land, the former are overlain by beds of Niag- 
ara or Wenlock age. 

The Trenton faunas, occurring in various places around the insular 
Archean nucleus of North America, have much in common, and this 
indicates that the conditions at that time were very similar, while the 
sea was in communication throughout. As yet, however, the distri- 
bution of the strata, together with their faunas, are well known only 
to the south and southeast of the Archean nucleus, yet that of the 
west (Manitoba) and of the northeast (Baffin Land) show direct com- 
munication. 

The Baffin Land ane had an early introduction of Upper Silurian 
genera in the corals Halysites, Lyellia, and Plasmopora. Ii Manitoba 
similar conditions occur in the presence of Halysites, Favosites, and 
Diphyphyllum. Other Upper Silurian types do not appear to be 
present. 

The Trenton fauna of Silliman’s Fossil Mount, at the head of Fro- 
bisher Bay, has seventy-two species, of which twenty-eight are 
restricted to it. This fauna shows an intimate relationship with that 
of the Galena of Minnesota, Iowa, and Wisconsin. Tifty-seven per cent 
of the species of Baffin Land also occur in the Galena of the regions 
just mentioned. 

The Trenton fauna of Baffin Land shows that the corals, brachiopods, 
gastropods, and trilobites have wide distribution, and are therefore 
less sensitive to differing habitats apt to occur in widely separated 
regions. On the other hand, the cephalopods, and particularly the 
pelecy pods, indicate a shorter geographical range. The almost complete 
absence of Bryozoa in the Baffin Land Trenton contrasts strongly with 
the great development of these animals in Minnesota and elsewhere in 
the United States.

SOME NEOCENE CORALS OF THE UNITED STATES. 


By HENRY STEWART GANE, Ph. D., 
Fellow in Geology, Johns Hopkins University, 1894-95. 


INTRODUCTION. 


At the suggestion of Prof. William B. Clark, of the Johns Hopkins 
University, the writer was encouraged to undertake the study and sys- 
tematic description of the Neocene corals of the United States. Further- 
more, the present paper has been constructed both as to method of 
treatment and arrangement of subject-matter upon the general plan of 
Professor Clark’s bulletin on the Mesozoic Echinodermata of this 
country. 

No attempt had been made hitherto to treat this subject from the 
present standpoint, the few corals previously described being offered to 
science either as possessing only zoological interest, or else to complete 
a local fauna. : 

The first mention of a Neocene coral from this country is found in the 
Petrefacta Germaniz of Goldfuss (1829), where Madrepora palmata is 
both described and figured. During the thirty years following this 
first description there were at irregular intervals a number of scat- 
tered contributions to the subject. The more important were those of 
T. A. Conrad, W. Lonsdale from the collections made by Sir Charles 
Lyell, and Milne-Edwards and Jules Haime. More recently there have 
been but two papers worthy of notice, one in 1887 by Prof. P. M. 
Dunean on the genus Septastrwa d’Orbigny, from the Miocene of 
Maryland, and one in 1888 by Dr. G. J. Hinde as a criticism of Pro- 
fessor Duncan’s article. It is of interest to note that the researches of 
Dr. Hinde on this American species are almost unprecedented, no sim- 
ilar coral having been treated in so exhaustive a manner. In consid- 
ering all the referetices we notice the somewhat remarkable fact that 
by far the most important writings have appeared both in foreign 
journals and from the pens of foreign paleontologists. 

The material treated has been loaned to the writer from the col- 
lections of the U. S. National Museum, Wagner Free Institute of 


PPOCEEDINGS OF U. S. NATIONAL MUSEUM, VOL. XXII—No. 1193. “te

Science, the Philadelphia Academy of Sciences, the private cabinet of 
Mr. Joseph Willcox, of Philadelphia, and the Johns Hopkins University. 
The state of preservation of the forms is as a rule excellent, with the 
exception of the silicified corals from Florida. These latter are often 
very difficult of determination, owing to prefossil wear and the minera- 
logical change the specimens have since undergone. Frequently the 
poorly preserved calices alone remain, the entire inside of the individ- 
ual or the colony being dissolved away and represented by a cavity 
with walls of botryoidal character. When the original substance of the 
coral, with the exception of the outer surface, is thus replaced, it becomes 
impossible, as an aid to identification, to cut sections showing the coral 
structure below the calice. The cause and method of silification of 
these corals has never been satisfactorily proven. Professor Heilprin,! 
in discussing the phenomena in his treatise on the Explorations on 
the West Coast of Florida, attributes the change to an infiltration of 
silica in a heated condition, but adds that he can not even hazard a 
guess, much less explain in what precise manner the peculiar method 
of hollowing was brought about. Especially is this true of the colonial 
types with botryoidal-shaped cavities. Furthermore, in the genera 
possessed of very small calices, as in Porites and Stylophora, their deli- 
cate structure is often so destroyed as to render a specific diagnosis 
impossible. 

The writer has also been at a great disadvantage from the fact that 
a number of the species have been described from single specimens, 
and until further collecting is done in the field it will be impossible to 
give a more detailed specific description of these forms. 

The fauna under discussion embraces in its geological distribution, 
the Neocene and Oligocene epochs. On the other hand, geographically 
the range of these forms is remarkably confined. With the single excep- 
tion of a few casts from the Miocene of Griswoldville, Fresno County, 
California, we find them limited to the Atlantic seaboard States, from 
New Jersey to Florida, inclusive. 

In considering this fauna as a unit, its most striking feature is the 


great number and variety of the genera represented as compared with 


the species, there being twenty-eight of the former to thirty-five of 
the latter. This proportion of genera to species is quite unusual, the 
number of species in any given fauna more often being far in excess 
of the genera. As an instance, we may cite the present fauna of 
Bermuda, with its twenty-eight species to only ten genera, or the 
results reported by the Challenger, which during its entire cruise 
obtained only sixty-nine genera of reef corals to two hundred and 
ninety-three species, and many of these presenting considerable varia- 
ation. We find, further, in taking account of the Neocene corals, that 
the colonial far outnumbers the individual type. 

In examining the bathymetric distribution of the species, it is doubt- 


1Trans. Wagner Free Inst. Sci., I, p. 62. 


NO. 1193. SOME NEOCENE CORALS—GANE. 181 


ful whether any truly deep-sea forms are » represented. The few genera 
that might be so classed are also frequently found living in shallow 
depths. When we add to the above the fact that they occur in the 
deposits side by side with true reef builders, we may consider that the 
corals living in the Oligocene and Pliocene periods flourished as shallow- 
water forms with preponderating reef-building tendencies. 

Both from their kind and the relations which the coral genera and 
species of a particular area bear to one another, it is possible to judge 
of the similarity or of the variation of the physical conditions prevail- 
ing in the region. 

Regarding this hypothesis, Prof. P. M. Dunean,! in ine first: article 
on the West Indian fossil corals, says: 


The range, in strata, of the genera of corals is often so great, and the species of 
remote formations are so frequently closely allied; that the Zoantharia form better 
guides for estimating the external physical circumstances of the regions in which 
they existed than for determining the age of the strata. There are few subjects 
better understood than the relation between the presence of certain genera and 
species of coral and certain definite, external physical conditions. Depth of sea, 
purity of sea water, its intense aeration, force of wave, absence of fresh water, the 
climate and nature of the coast line, with all their possible varieties, appear to 
determine, according to their mutual reactions, the presence and persistence of spe- 
cies and genera. Indeed, very slight variations from the general rule of the external 
circumstances in a coral sea would appear to prevent the development of certain 
genera. It is a reasonable induction that, if a species be found in strata of any 
age and distant in space, the two sets of strata were formed under the same external 
physical circumstances. 

If this be true, then the conditions prevailing upon the Atlantic 
coast during Neocene time were most varied, both from a geological 
and a geographical standpoint; for we find that in the fauna under dis- 
cussion the genera of the corals are quite varied, and that the indi- 
vidual species are very limited, both vertically and horizontally, in their 
stratigraphic distribution. In this distribution the Pliocene species 
are perhaps more liable to be limited in their geographical range than 
in their geological, since a number of the forms are either found as 
recent or having closely related living allies, whereas the Miocene 
_ Species appear to be about equally confined both from a geographical 
and a geological aspect. 

A majority of the corals represented belong to extinct species. A 
few are now found living in the Caribbean Sea, and some belong to 
closely allied fossil forms from Santo Domingo and other West Indian 
islands. 

We should expect that the Neocene corel of the United States would 
have close kinship with those of like age in the West Indies, but such 
does not seem to be generally the case. On the other hand, according 
to Professor Duncan the fossil Oligocene corals of the West Indies are 
closely related to those of the Miocene of Europe ai.d the recent faunas 
of the Pacific and Indian oceans. Regarding the affinities of. the Neo- 


1Quart. Jour Geol. Soc., XIX, p. 453. 


182 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXII. 


cene fauna of the United States as a whole, we come to the conclusion 
that it has more of a likeness to that at present living in the Caribbean 
Sea and Atlantic Ocean than to the fauna, recent or fossil, of any other 
region. f 

The descriptions of families and genera will not be repeated in the 
present work, as they are to be found in the paper of Prof. P. Martin 
Dunean on “A Revision of the Families and Genera of the Scleroder- 
mic Zoantharia, Hdwards and Haime, or Madreporaria (M. rugosa 
excepted),” which also contains the system of classification employed 
in the present memoir. 

The author wishes to express his thanks, through Mr. William H. 
Dall and Mr. Joseph Willcox, to the Wagner Free Institute of Science 
tor the loan of many of the specimens herein described; also to Mr. T. 
Wayland Vaughan for much kindly assistance and advice. Mr. 
Vaughan has looked over the paper after it was written and has 
attended to having the figures drawn.

Corallum quite variable in shape, more or less compressed, conical, 
attached at base by a moderately long pedicle, which may be either 
broad or narrow. Surface of the wall and costal ridges smooth, at times 
showing the development of an epitheca. Cost well developed, cor- 
responding to all septa, more prominent near the calicular margin, 
margins not acute, some granulations over the surface. The summits 
of the calice in the shorter diameter are higher than in the longer. 
The margin of the calice is irregularly dentate. The interior of the wall 
coarsely pitted here and there between the septa. There are six sys- 
tems of septa with four well-developed cycles, and a fifth rudimentary. 
The septa are exsert, rather stout, thicker near the wall and in the 
vicinity of the base of the calicular fossa; they are generally straight 
but often curved, with granulated sides, and the surface often shows 
quite distinct striations. In well-preserved specimens the fossa is deep 
and narrow, and the free margins of the septa at the base of the fossa 
often form by means of small rod-like projections a sort of columella as 
in Flabellum. 

Such a pseudocolumella similar to that found in the present species 
is described by Mr. H. N. Mosely ' in his report on the “‘ Deep Sea Madre- 
poraria” as occurring in the Desmophyllum ingens from the fjords of 
western Patagonia. 

This species is respectfully dedicated to Mr. Joseph Willcox, of Phila- 
delphia. 

Dimensions.—The dimensions of the largest specimen are: Height, 28 
mm.; greatest length and least width of calice, respectively, 32 and 
25mm. The calices of the majority of the specimens are, however, 
more compressed than in this one.

Corallum small, broad and iow, with the calice about the same diam- 
eter as the base, above which the wall is somewhat constricted. Wall 
thin, costulate to its base. Cost« low, unequal, finely granular, more 
prominent near the calicular margin where they are considerably 
thicker than their corresponding septa. Calice circular in the young, 
slightly oval in the adult individual; fossa broad, moderately deep. 
Septa in six systems of five cycles lacking part of the sixth order of 
the last cycle; in forms of medium size, only four cycles are present. 
Primaries and secondaries subequal, thick and stout, with summits 
more broadly rounded and more strongly exsert than those of the 
remaining thin and slender septa; sides coarsely granulated, edges of 
the higher cycles regularly crenately dentate. Pali granular, present 
before all the septa but those of the last cycle, excepting in the most 
mature forms, where they may be lacking before a part of the fourth as 
well as before all of the fifth cycle of septa. Columella papillose, well 
developed. 

In polishing down the base of the coral, the rings marking the ex- 
istence of previous outer walls are clearly seen. In one specimen no 
less than eight appear, showing the growth of the coral and its rela- 
tion to the development of its septa. 

The individuals of this form generally occur alone attached to some

Colony forming a palmate mass with more or less coalescing branches. 
In specimens which are not water worn the cost are quite distinct at 
the calicular edge and bent, passing at times into slight flattened ridges 
on the surface of the coenenchyma. Calices slightly unequal and 
separated by irregular distances from one another, moderately deep, 
and projecting somewhat above the coenenchyma. Septa in two cycles 
of about equal size, with a third cycle, generally rudimentary, at times, 
however, fully developed; narrow, coarsely toothed with granular sides. 
The septa often unite in the center forming a small somewhat spongy 
columella. 

This coral is of interest as being the first described from the Neocene 
of this country. 

Dimensions.—Breadth of calice from 2 to 3 mm. 

Geological horizon.—Miocene, Chesapeake formation.

Corallum simple, nearly straight, conical, at times constricted verti- 
cally so as to appear more or less bilobate, pedicellate. Epitheea well 
developed and membraniform. Cost large above, projecting outward 
2.5 mm. from the calicular margins; edges rounded and marked by 
tubercles; sides granulated at their upper extremites in radiating rows 
extending over from the septa. Exotheca frequently present between

the costz, inclined, and forming cells. In the largest specimens the 
calicular area is somewhat less than that of a transverse section of the 
coral about 15 mm. below the margins. Calice variable in shape from 
quite oval tocompressed, sometimes constricted centrally, approximating 
in shape the figure eight; itis shallow and presents a wavy margin ona 
nearly even plane in the adult, uneven in the young. The fossa is deep 
and narrow. ‘There are six systems with five complete cycles of septa, 
and in the adult individuals sometimes several orders of a sixth. The 
septa are crowded, often curved, a little thicker at the wall than else- 
where, marked on their upper edges with a very slight serration of 
small papillz; the sides have radiating rows of granules which merge 
with those on the cost; this regularity of granular arrangement is not 
so marked in the vicinity of the lower part of the fossa. Columella 
long, dense, and spongy.* Endotheca abundant. 

When comparing the coral at different stages in its growth, this 
species is very variable in shape. In the young forms, we find the 
corallum more conical than turbinate, more strongly attached, and 
its calice much more oval and not at all resembling the figure eight in 
outline. The margin of the calice is more sinuous, with the longer axis 
more depressed than the shorter. Epitheca less prominent. Septa in 
only four cycles, straighter and less crowded. Fossa deeper than in the 
adult form. 

The number of specimens examined by the writer is numerous, rep- 
resenting quite a series of individuals of most varied size and shape. 
Had either of several extreme types occurred alone without the con- 
necting forms it might well be considered as a distinct species. 

The young are but slightly, if at all, bilobed, the most matured indi- 
viduals alone being turbinate and vertically constricted with a figure 
eight shaped calice, the latter characteristics being described by Pro- 
fessor Duncan as typical of the West Indian forms. 

Dimensions.—The dimensions of the largest specimens are: Height, 50 
mm.; greatest length and least width of calice, respectively, 59 and 25 
mm. When comparing the above measurements with those of the 
largest specimens from Santo Domingo, the latter are found to be far 
larger in size than the forms occurring in Florida. 

Geological horizon.—Upper Oligocene, Chipola formation. 

Locality.—Bailey’s Ferry, Chipola River, Calhoun County, Florida; 
Santo Domingo, Guadeloupe (horizon not given), West Indies.

Colony encrusting, consisting of conical or cylindrical corallites, the 
largest sometimes rising a centimeter above the surface of the bas. 
expansion. Individual corallites divergent, but usually touching at 
their bases. Walls very thin at their calicular edge, thicker below. 
Hpitheca extremely thin, finely granulated and in some forms sl.owing 
parallel, somewhat sinuous, flat and broad strive extending to the base. 
True costz of unequal size are at times present in the vicinity of the 
ealicular edge. Calice as a rule circular, at times considerably 
compressed, deep. Septa much narrowed at the top, in mature forms in 
four complete cycles; septa of the last cycle much thinner and narrower 
than those of the preceding, often merely rudimentary; in the younger 
individuals septa but thirty-six; there is a tendency for the younger 
septa to turn toward and unite with the older; inner edges strongly 
dentate, teeth slightly coarser nearthe columella; sides granulated, 
though not stoutly so. Columella small and formed of a net-work 
of trabicule with additions from the septal ends. Multiplication by 
budding chiefly from basal expansions, although it may take place well 
up on the side of a parent corallite. 

The writer refers this species to the genus Astrangia, although there 
is more of an epitheca present than has been hitherto considered as 
characteristic of the genus. In all other respects this species seems 
to be typical. Lonsdale, in his description of the coral, states that it 
closely resembles the Lithodendron flecuosum described by Michelin in 
his Iconographie Zoolphytogique, from the faluns of Touraine, but 
Edwards and Haime have since pronounced the species of Michelin to 
be a Cladocora. As this American species lacks pali and possesses 
neither a shallow calice nor septa quite exsert, it can not belong to the 
genus Cladocora. 

Dimensions.—Breadth of calice, from 4 to 8 mm. 

Geological horizon.—Miocene, Chesapeake formation.

NO. 1193. SOME NEOCENE CORALS—GANE. 189 


Colony encrusting, of closely ‘united corallites often free at their 
summit. Walls minutely granulated on the exterior surface. Coste 
present, most distinct near the calicular edge. Cailices open, deep and 
circular except when crowded. Septa very slightly exsert, narrowed 
at top, in six systems of three complete cycles with part of a fourth; 
those of the third cycle a little narrower than the preceding, uniting 
with them inferiorly and near the columella; edges sharply and some- 
what coarsely dentate; sides granulated. Columella well developed, 
papillary, the outer part resembling the inner teeth of the septa. 
Gemmation both from marginal buds on the basal expansion and from 
the sides of the coral between the parent corallites. 

This species is found recent on the shores of the Atlantic from 
North Carolina to Florida. It is very nearly related to Astrangia dane 
Agassiz, occurring on the coast of this country from New Jersey to 
Massachusetts. It also in many respects resembles the fossil Astrangia 
lineata from the Virginia Miocene.

Colony incrusting, rising at times into lobate extensions. Corallites 
thin walled, closely united. Calices irregularly prismatic, quite deep, 
with their fosse narrow at the bottom. Septain three complete cycles, 
the third less stout and usually curved toward and united, near the 
columella, to those of the preceding cycle; occasionally part of a 
fourth cycle is developed. Septa thin, with free edges sharply and 
roughly denticulated throughout; sides somewhat coarsely granulated, 
frequently the granules being also present on the inside wall of the 
calice. Columella moderately developed, spongy, composed of con- 
torted processes originating from the inner margins of the septa. 
Gemmation takes place in the interspaces between the corallites. 

This species is closely related to the living Cwnangia conferta of 
the Pacific, and Astrangia dane Agassiz and Astrangia astreiformis 
of the Atlantic.

Colony incrusting, at times rising into lobes in the middle. Corai- 
lites in close contact but the individual walls distinct. Calices crowded, 
irregular in size and shape, oval, circular, and polygonal, the latter pre- 
dominating, moderately deep, with perpendicular walls. Interseptal 
chambers very wide. Septa subequal in two cycles, thin, the free edge 
subentire and concave; uniting at their inner margins to form a pseudo- 
columella. Walls and septa of the calices completely covered with 
minute tubercles. Dissepiments scarce. Growth of corallum by bud- 
ding of young corallites from between the angles of the older cells. 
This species is common in the Miocene bluffs of the James River, 
Virginia, where it is generally found incrusting the surface of the 
Pecten jeffersonius. 
In the opinion of the writer this apparently distantly related coral 


will, upon further study, prove to have close affinities with the Septas-_ 


trea sexradiata of Lonsdale. 

The nearest living ally to this form, according to Professor Verrill, is 
the Cenangia conferta of the Pacific Ocean. The latter, however, differs 
from the fossil coral in possessing usually 24 septa and only moderately 
wide interseptal chambers; the walls are thinner; the septa have 
larger lateral granules, and the columella is more strongly developed. 
Professor Verrill further adds! “‘that the close relation of this living 
(Pacific Ocean) species to the fossil and recent species (Astrangia dane 
and Astrangia astreiformis) of the temperate coasts on the Atlantic

side, together with the occurrence of certain shells that are apparently 
identical in the two regions, but found neither in the arctic nor in the 
tropical regions, is very suggestive of a former connection, perhaps in 
early tertiary times, between the two oceans, through the temperate 
‘parts of North America.”

PHYLLANGIA FLORIDANA Gane. 
(Plate XV, figs. 7-9.) 


1895. Phyllangia floridana GANE, Johns Hopkins Univ. Circ., XV, No. 121, p. 9. 

Colony encrusting, consisting of subturbinate corallites arising from 
the basal expansion. Individuals generally free above but somewhat 
closely united at their base. Walls thin at the calicular edge, thicker 
below. Coste low, subequal, minutely granulated, reaching to the base, 
but more prominent at the calicular margin and at the swellings just 
beneath the constrictions in the walls of the corallites. About on a 
level with the bottom of the fossa, the diameter of the corallite is least, 
the walls being here somewhat constricted, beneath which constriction 
they are again frequently swelled to a diameter equal to that at the 
calicular margin. Calices somewhat expanded, widely open, deep, 
narrow at the bottom. Septa crowded, in six systems of four complete 
cycles, lacking a few septa of the fifth order; primaries and secondaries 
more exsert, thicker and broader than the septa of the following cycles, 
quarternaries least exsert, thinnest and narrowest; sides of the septa 
sharply granulated and the edges of all but the fourth cycle rounded 
superiorly and subentire in their upper parts, the lower two-thirds of 
the septal edges being strongly lobate or dentate, the uppermost tooth 
being the most prominent and similar in shape to a true paliform lobe. 
Columella papillary occupying a very limited area; the line of separa- 
tion between the papille of the columella and the lowest teeth of the 
septa being indistinguishable. Gemmation by budding from the basal 
expansion of the wall of a parent corallite. 

This form in its general size and mode of growth very much resem- 
bles the Astrangia lineata (Conrad) of the Virginia Miocene deposits. 

Dimensions.—Breadth of calice, from 4 to 6 mm. 

Geological horizon.— Pliocene, Caloosahatchie beds. 

Locality—Alligator Creek, Monroe County, Florida.

CLADOCORA JOHNSONI Gane. 
(Plate XV, figs. 10-12.) 
1895. Cladocora johnsoni GANE, Johns Hopkins Univ. Cire., XV, No. 121, p. 10. 


Corallites slender, somewhat flexuous, and cylindrical. When found 
fossil they are detached from the parent colony. Walls of moderate 
thickness. Cost granular, well developed, and close set; those corre- 
sponding in position to the septa of the first and second cycles of the 
same size, and larger than those corresponding the members of the 
third and fourth cycles. With the exception of a few cost of the 
fourth cycle, all reach to the base of the corallite. Calices circular 
with a shallow fossa. There are six systems of three complete cycies, 
with occasionally a few rudimentary. septa of an incompleted order of 
a fourth cycle. Septa exsert, the primaries more prominently so, 
rounded and very finely granulated laterally, giving the lamine a 
slightly striated appearance; primaries thicker and broader than 
secondaries, which, in turn, have a similar relation to the tertiaries. 
In sections of a corallite below the ecalice, the septa of the third cycle 
approach and midway between the theca and columella unite with 
those of the preceding cycle. Either true pali or paliform lobes are 
present before all but the last cycle of septa. Columella coarsely 
papillary but rather narrow. Gemmation lateral and often in pairs at 
the same height on the stem. 

The nearest related form to this Pliocene coral seems to be the 
Cladocora debilis Edwards and Haime, recent at Maderia, but owing 
to its meager descriptions the writer can not speak definitely on this 
point, as he has not had an opportunity of examining specimens of the 
species. 

The present form is named after Mr. Charles W. Johnson, of Phila- 
delphia, who has added so much to our knowledge of the Neocene 
paleontology of the South. 

Dimensions.—Height of the largest specimen, 12 mm.; breadth of 
calice, from 2 to 2.8. :

Colony very variable in shape, with a sinuous outline, from compressed 


conical to subhemispherical; attached by a slender pedicle, the lower 
part of the base curved in the direction of the greater axis of the 


‘NO. 1193. SOME NEOCENE CORALS—GANE. 193 


colony. Valleys rather wide, long and deep, having perfect communi- 
cation between them. Corallines broad and furrowed. Wall thin. 
Epitheca well developed, pellicular; its lines of growth in wavy ridges 
of varied thickness, the thinnest of which are pierced by the granules 
of the costz; im some cases it is limited to the lower part of the base, 
in others it reaches to the summit of the outer wall of the colony. 
Coste of nearly equal size, the oldest only reaching the pedicle; con- 
siderably exsert, being a continuation of the septa at their upper 
edges; finely toothed on the free edge, rows of granules on the sides. 
Exotheca abundant. Septa quite exsert, slightly thicker at the wall, 
granulated laterally in radiating rows, with free edge regularly toothed, 
the teeth being somewhat larger near the paliform lobe, which is some- 
what thicker, at least near the columella, than the principal septum to 
which it belongs. Columella well developed, narrow, of a coarse 
spongy nature, especially when seen in vertical section. Endotheca 
abundant, with dissepiments of unequal length inclined toward the 
inner and lower edges of the septa. 

Pourtales' considered that all the living West Indian types of this 
genus represented one species, the Manicina areolata (Linneus). 
Whether this be true or not, the species under discussion differs from 
all recorded living forms. More especially it varies from Manicina 
areolata in the following particulars: Its collines are generally broader; 
the septo-cost of adjoining individuals are rarely united, the walls of 
the individuals being distinct; septa somewhat stouter and less crowded 
together, in very rare cases only exceeding eleven in number to the 
centimeter; the teeth on the inner edge of the septa are more regular 
in size and shape. On the other hand, in Manicina areolata the col- 
lines are narrow, with many of the septo-coste of neighboring indi- 
viduals united. The septa are thinner and more crowded, from fifteen 
to twenty (Quelch) to the centimeter. The teeth on the inner edge 
vary more in different parts of the same septum. This differentiation 
of the teeth on different parts of the edge of the septum and paliform 
lobe, as shown by the living types, is well illustrated in the “Report on 
the Florida Reefs” by Agassiz.’ 

Dimensions.—This species is very variable in size and shape. The 
greatest width of one corallum measured is 100 mm.; length, 150 mm. 
(estimated); height, 80 mm.; of another, width, 55 mm.; length, 135 
mm.; height, 55 mm.

Colony incrusting at base, rising into cylindrical compressed stems 
with short, rounded branches or of large flattened masses with lobate 
and digitiform expansions. Corallites with walls in close contact but 
distinct one from another, subeylindrical in the interior, although pris- 
matic at the surface of the corallum. The matured calices are shallow 
with thickened margins, an impressed line generally marking the 
division between the individuals; the floors of the calices, which have a 
dome-shaped elevation in the center are entirely closed with stereo- 
plasm, the upper edges of the septa alone shghtly projecting. When 
the calices are immature or much crowded the walls are thin and the 
floor near its periphery is incomplete. The entire calice when per- 
fectly preserved is covered with minute tubercles, although the surface 
of the septa in the interior of the corallites is smooth. Septa usually 
12 in the lower portion of the corallite; in the calice a rudimentary 
third cycle is often added. Abnormally the calice may possess from 0 
to 36 septa. The inner septal ends are often intertwisted to form a 
pseudocolumella. Dissepiments very thin, irregularly developed, fre- 
quently at the same level in the different interseptal loculi, usually 
from 1 to 2 mm. apart, the uppermost dissepiment of the corallite form- 
ing the base to the infilling stereoplasm. Increase by gemmation from 
buds formed at the interspaces between the walls of adjacent mature 
corallites.

For a further detailed and most elaborate description of this coral 
consult the paper by Dr. G. J. Hinde on the genus Septastrwa in gen- 
eral, and the present species in particular. Nothing but the mode of 
attachment is now added to the characteristics of the form as so clearly 
determined by Dr. Hinde. 

The present writer, however, considers the Septastrea forbesi Kd- 
wards and Haime, as a synonym of the S. sexradiata Lonsdale. In 
discussing the similiarity of the two species Dr. Hinde! aptly sum- 
marizes the subject in the following words. He says that— 

It is very evident that in form, mode of growth, and in every other feature but 
one, this species (S. sexradiata) is closely similar to Septastrwa forbesi. The one fea- 
ture in which it differs is the greater development of the third cycle of septa within 
the calices. This feature, curiously enough, is limited to the calices, for in the lower 
part of the corallites only the 12 septa of the first and second. cycles are devel- 
oped, as in S. forbesi, so that specimeus in which the surface features are partially 
obliterated can not be distinguished from this latter species. I have serious doubts 
whether this one feature may not, after all, be due to a more favorable condition of 
growth or environment to which this particular specimen has been exposed. It is 
somewhat remarkable that of the thirteen specimens of Septastrwa which have come 
under my notice this is the only one which exhibits such a development of the third 
eycle of septa in the calices; in all others this cycle is only indicated by marginal 
ridges. There is a considerable amount of variation in this respect in the specimens 
referred to Septastrea forbesi, for in some only 6 septa are developed in the calices, 
in others 12, and yet no specific distinction can be made, since in certain specimens 
both conditions are present. It might therefore be urged that, as Lonsdale’s speci- 
men is undistinguishable in every other respect from Septastrwa forbesi, the difference 
in this variable feature does not possess specific value. While admitting the force 
of the argument, I think it is preferable provisionally to allow the difference to be 
specific, and if further evidence should show that it must be regarded as merely 
due to external conditions, and that there is only one species, then this species 
must bear Lonsdale’s name of sexradiata, since this has the priority of Edwards avd 
Haime’s name, forbesi. 


As the fori under discussion is the most common coral occurring in 
the beds of the Virginia Miocene, the writer has had an opportunity of 
studying a large series of specimens, and has reached the conclusion 
as stated above that all belong to the same species, although in the 

superficial calices there is often a remarkable divergence in the rela- 
tive development of the septa and the pseudocolumella. Were the 
Septastrea forbesi allowed of specific value, then a number of new spe- 
cific names should be employed for these forms with calices, either con- 
taining but 6 or less septa, or with the septa of the latter cycles united 
with those of the preceding, or with the other similar modifications in 
the calice. 

That both Mr. Lonsdale and Sir Charles Lyell considered these Sep- 
tastrea as of one species, the S. sexradiata is evinced by the fact that 
the former, who described the forms, gave but one specific name to them, 
and the latter, who collected the specimens, stated? that lying on the 
beach of the James River were masses of the S. sexradiata upward of 


2Tdem., I, 1845 p. 416. 


196 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXII. 


2 feet in width, which had been washed out of the shell marl. The 
above would show that both Lonsdale and Lyell regarded the coral 
described as representing the specimens collected rather than of:a 
peculiar variety as has been since considered by later writers, with the 
possible exception of Dr. Hinde, who desired further information on 
the subject before finally committing himself. 

The first reference to this coral is found in 1837 as a footnote to an 
article! on the gevlogy of the Tertiary formations of Virginia by W. B. 
and H. D. Rogers. They remark that an Astrea of immense magnitude 
was lying at that time half buried in sand on the beach of Tarbay, James 
River, having fallen to its present position from an overhanging cliff. 
They add further that it was much reduced in size since its fall, but had 
then an approximate weight of 700 pounds and a diameter in its greatest 
length of 4§ feet. Mr. Arthur Bibbins has recently secured this his- 
toric specimen for the Geological Museum of the Woman’s College of 
Baltimore where it is now preserved. 

Dimensions.—The largest specimen is about 1.5 meters in its greatest 
diameter; breadth of calices from 3 to 8.5 mm. with an average width 
of 4.6 mm. 

Geological horizon.—Miocene, Chesapeake formation. 

Locality.—Bellefield and Yorktown on the York River, and at many 
points on the James River, Virginia. In some of the previous papers 
on the subject this coral is frequently mentioned as coming from Mary- 
land, but none of the specimens in the collections examined by the 
writer came from that State. 

Collections.—U.S. National Museum; Philadelphia Academy of Natu- 
ral Sciences; Wagner Free Institute of Science; Johns Hopkins Uni- 
versity; Woman’s College of Baltimore.

A NEW FOSSIL SPECIES OF CARYOPHYLLIA FROM CALI- 
FORNIA, AND A NEW GENUS AND SPECIES OF TURBI- 
NOLID CORAL FROM JAPAN. 


By T. WAYLAND VAUGHAN, A. M., 


Assistant Geologist, U. S. Geological Survey. 


iN NEW FOSSIL SPECIES OF CARYOPHYLLIA FROM CAL- 
IFORNIA. 


The coral described below was in some material sent by Mr. Ralph 
Arnold, of Leland Stanford Junior University, to the U.S. National 
Museum to be named. Mr. W. H. Dall kindly placed the specimen in 
my hands for determination. As it proved to be undescribed, the 
following diagnosis has been prepared. 


CARYOPHYLLIA ARNOLDI, new species, 
(Plate XVI, figs. 1, 2.) 


Form of corallum slightly deformed inverted cone-shaped. A basal 
scar present, but the coral in its later stages was evidently unattached. 
Base subacute, calice nearly circular in transverse outline. 

Dimensions.—Greater diameter of calice, 16 mm.; lesser diameter of 
calice, 15.3 mm.; height of corallum, 16.5 mm.; depth of fossa, about 
6.5 mm. 

Coste very distinct, low, broad, rounded, or flattish, show no orna- 
mentation, but the specimen is worn and they were probably minutely 
granulated. There is a tendency to alternation in size, which is pro- 
nounced near the base. There is no observable epitheca. The wall is 
stout, solid, a distinct pseudotheca. The cost are wide and the inter- 
costal spaces very narrow, simply furrows, and the septa are thickened 
at the wall. The upper margins of the septa project very slightly above

200 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXII. 


the upper limit of the corallum wall. There are four complete cycles 
of septa (forty-eight in all), arranged as follows: Twelve large thick 
septa, joined to the columella by very thick pali. The width of each 
palus is equal to the width of its corresponding septum; the upper 
margins of the palus stands about 2 mm. above the upper surface of 
the columella, and fully 1 mm. above the notch dividing the palus from 
the septal lamina. The width of the paliis about 2.5mm. From the 
upper margin of the septum to the notch between septum and palus is 
about 4.5 mm., may be slightly greater. Theinner ends of the pali are 
fused solidly around the columella and to it. On the septal faces are 
small granulations arranged in curves parallel to the upper septal mar- 
gins. On the faces of the paliare granulated or serrated crests arranged 
in curves parallel to the upper margins of the pali. Between each pair 
of these larger septa are three smaller (one of the third cycle and two 
of the fourth). The members of the third cycle are narrow above the 
level of the upper termination of the columella; below this they widen, 
but do not seem ever to reach the columella. The members of the fourth 
cycle are narrow, and thin except where they arch over the walls. The 
columella is essential, is composed of several pieces, trabeculze, which 
are firmly soldered one to another and to the inner terminations of the 
pali by solid basal calcareous deposit. From the upper margins of the 
septa to the upper termination of the columella is about 6.5 mm.; that 
is, the calicular fossa is about 6.5 mm. deep. The greater diameter of 
the upper termination is 5 mm., the lesser 3.5 mm., above whose level, 
as may be gathered from what preceded, the pali form a regular crown. 

Locality—San Pedro Hill, San Pedro, California. 

Geological horizon.—Pleistocene. 

Type.—Cat. No. 157509, U.S.N.M. 


A NEW GENUS AND SPECIES OF TURBINOLID CORAL 
FROM JAPAN. 


The specimen upon which the subsequent descriptions are based was 
sent to the U. S. National Museum by Rev. H. Loomis, Yokohama, 
Japan. Mr.W.H. Dall asked me to determine it, and as it proves to 
belong to both a new genus and species, the following generic and 
specific diagnoses have been prepared: 


LEVIPALIFER, new genus. 


Salient generic features.—Simple Turbinolid; corallum very short, 
inversely conical in shape, almost discoid; no sign of attachment, living 
free. Wall naked. Septa within the wall possess entire or faintly 
crenate margins; external to the wall beset with rounded dentations. 
Coste dentate, the dentations with blunt or rounded ends. Four com- 
plete cycles of septa; palit are before all septa and have entire margins. 
Columella essential, trabecular. 


NO. 1194. TWO NEW TURBINOLID CORALS—VAUGHAN. 201 


LEVIPALIFER ORIENTALIS, new species. 
(Plate XVI, figs. 3-7.) 


Corallum, without any sign of attachment, subdiscoid in form, the 
base pointed. Transverse outline of the calice circular. 

Dimensions.— Diameter, 20 mm.; altitude, 9 mm. 

Cost well developed, thin, distant, correspond to all septa; those of 
the first and second cycles of the same size; those of the third slightly 
sinaller, and those of the fourth still smaller. They are rather tall at 
the calicular edge of the wall, becoming lower as the base is approached. 
Two cycles are continued to the apex of the base. The costal margins 
are beset with rather tall, rounded or blunt dentations. In some 
instances the ends of the dentations are swollen. Each dentation 
marks the emergence on the surface of a small ridge (or stria) along 
which are arranged rather tall but not very sharp pointed granulations. 
The lateral faces of the cost are perpendicular to the corallum wall; 
that is, the costz show no, or almost no, thickening at the wall. 

There are four complete cycles of septa, arranged in six definite sys- 
tems. Six of the septa stand isolated from the other septa and extend 
directly to the columella. Between each pair of these six is a definite 
group of septa belonging to higher cycles. Those of the third cycle 
bend toward those of the second, and the members of the fourth bend 
toward those of the third. Quite frequently the members of the fourth 
cycle are longer than the inclosed members of the third. The longer 
member of the fourth cycle for any given half system is the one stand- 
ing next to the septum of the first cycle. This arrangement is the 
common one in the Kupsammide. The fusion of the septa into the 
groups above indicated is affected by the pali. The lateral ornamenta- 
tion of the septa consists of ridges or strive, which possess a line of 
_ divergence slightly interior to the wall and parallel to it, and granula- 
tions placed along the striz. Within the line of divergence the striz 
bend toward the interior of the corallum, and exterior to it they bend 
outward, ultimately downward. On the inner side of the line of diver- 
gence the septal margin is entire or shows very faint crenations. 
Exterior to it each ridge is terminated by a dentation, not very 
long just at the line of divergence, but quite soon the dentations are 
larger. The dentations on the peripheral ends of the septa, that is, 
the cost, have already been described. When one looks directly at 
the edge of a septum the strizw are seen to alternate in position, and 
the septum is usually faintly undulate in a direction parallel to the 
long axis of the strie. The granulations are placed along the strize 
and are arranged in curves parallel to the septal margin. The granu- 
lations are rather tall, but are not sharp-pointed; their tips are blunt 
or rounded. The septal margins project considerably above the upper 
edge of the wall; the members of the first and second cycles are equally 
prominent, and are more exsert than those of the third and fourth

cycles, which are equal in prominence. The septa are distant, thin, 
weak, and show no marked thickening at the wall. 

Pali are before every cycle of septa. Those before the first cycle 
are the broadest. The pali belonging to each septal group included 
between the members of the first cycle are deltoid in arrangement. 
The arrangement is well shown in Plate XVI, fig. 6. The pali are 
broad and are simple lobes, excepting usually there is an inner tooth 
before the delta composed of the pali of each group of septa of the 
third and fourth cycles. The margins of the pali are entire. The trabec- 
ular make-up of the pali is the same as that of the septa; each palus 
has its own line of divergence, etc. The fusion of the septa into deltas 
through the pali is effected usually by synapticula. Excepting these 
synapticula the interseptal loculi are entirely vacant. 

Some hints have already been thrown out as to the make-up of the 
wall. It is entirely naked, imperforate, and rather thin, thickening 
very little from internal calcareous deposit; no processes extending 
inward from it between the septa (such as are quite common in some 
Turbinolid genera) were seen. As the septa and cost do not thicken 
in crossing the wall, this coral would be said to possess a eutheca. In 
my mind the point to be emphasized is that the septa are distant and — 
thin, and the connecting wall is also thin. The wall between the cost 
possesses no ornamentation. 

The columella is large, well-developed, trabecular, and spongy. 

Locality.—Boshiu (Awa), eastern coast of Japan. 

Type.—Cat. No. 19391, U.S.N.M. 

Bathymetric distribution not known. 

Remarks.—The natural group to which this coral belongs is very 
evident. It is very closely related to Trochocyathus and Deltocyathus. 
It is separated from the latter genus solely by possessing one more 
crown of pali. The genus Leptocyathus Milne-Edwards and Haime, 
was founded to receive the coral from the London Clay, designated by 
them Leptocyathus elegans,' which, according to them, possesses dentic- 
ulate pali before all cycles of the septa. The pali of Leptocyathus, 
according to the figure (Plate III, fig. 6c), are small, and do not exhibit 
a noticeably deltoid arrangement. There are other differences; the 
septa are much thickened at the wall, and the cost possess very broad 
bases. Pourtales? has described a species, found off Conch Reef and 
Tennessee Reef, Florida waters, as Leptocyathus stimpsoni. I doubt if 
this coral is really a Leptocyathus. It possesses many points of differ- 
ence from the type species L. elegans, and certainly is not closely related 
to the species here described. 

It may be repeated that Levipalifer is most closely related to 
Deltocyathus.

NOTES ON BIRDS COLLECTED BY DOCTOR W. L. ABBOTT 
IN CENTRAL ASIA. 


By HARRY C. OBERHOLSER, 
Assistant Biologist, Department of Agriculture. 


‘Dr. Abbott’s earliest collections of birds from Cashmere and Ladak 
have already been fully treated by Dr. C. W. Richmond.’ Upon leav- 
ing Madagascar, in 1895, Dr. Abbott proceeded again to Cashmere, 
where he spent the remainder of the year—some four months—mostly 
in places previously visited. Again, in 1897, he was there for a month 
or So from about the middle of October, having come from Ladak, in 
which latter region, at various localities, he had been collecting since 
the middle of June. 

As the ornithological results of these later visits to Central Asia, the 
United States National Museum has duly received two consignments 
of specimens; and at the request of the curator of the division of birds 
a list of them is here presented. Although these collections number 
together only 142 specimens, representing 62 species, they comprise 
several birds of considerable interest and a number not previously 
obtained by Dr. Abbott. All matter within quotation marks is to be 
credited to the collector. 

The writer is under obligation to Dr. Richmond for his uniform 
courtesy during the preparation of this paper, as well as for permission 
to make use of his notes upon several of the larger species.

Two adult females in somewhat worn breeding plumage, from Tsokr 
Chumo Lake, Ladak, at 15,000 feet altitude, July 13,1897. ‘Tris pale 
greenish; orbital skin red; feet red; billdark red. Length, 163 inches.

LARUS RIDIBUNDUS Linneus. 


Larus ridibundus LINN2US, Syst. Nat., 12th ed., I, 1766, p. 225. 

One specimen, from the Valley of Cashmere. This is an adult male 
in winter plumage, with no brown hood, and with dusky only ou aurie- 
ulars; the black and white areas on primaries are very sharply defined. 
“Trides blackish brown; feet red; claws black; bill red, the tip black. 
Length, 16 inches.” 


STERNA HIRUNDO TIBETANA (Saunders). 


Sterna tibetana SAUNDERS, Proc. Zool. Soc. Lond., 1876, p. 649. 

Two adult males: one from the Indus River at Mya, Ladak, 13,000 
feet, September 11,1897; the other from Tsomoriri Lake, Ladak, 15,000 
feet, July 29,1897. ‘‘ Length, 134 and 142 inches, respectively. Iris 
dark brown; bill red, the tip black; feet red; claws black.” 

Careful comparison with a large series of American and European 
specimens indicates that the bird from Thibet, though not specifically 
distinct from S. hirundo, is yet well worthy of separation as a geograph- 
ical race, to which the name tibetana is applicable. This central Asian 
form is much darker on the mantle and much less whitish on the nape; 
the lower parts also are of a deeper gray, particularly on the flanks. 


Family CHARADRITDAE. 
OCHTHODROMUS INCONSPICUUS (Wagler). 


Charadrius inconspicuus WAGLER, Isis, 1829, p. 651. 
Charadrius pyrrhothoras GOULD, Birds Europe, IV, 1837, pl. 299. 
Agialitis pamirensis RICHMOND, Proc. U.S. Nat. Mus., X VIII, 1896, p. 589. 

Six specimens (four adult males, one female, and one immature male) 
from various localities in Ladak, at from 14,000 to 15,000 feet; taken 
July 7 to 20, and September 8, 1597. Among the males the amount and 
shade of the ochraceous on the crown varies considerably, and on the 
upper tail-coverts of one specimen there is very little brown; otherwise 
all are very similar. There are a few small flecks of white in the black 
of the forehead and lores, particularly the latter, but this effect is due 
to the wearing off of the black tips of the feathers, with its consequent 
exposure of the white basal portions, and would probably not be notice- 
able in fresh plumage. “Length, 74 to 74 inches. Iris dark brown; 
bill, feet, and claws black.” 

Dr. Sharpe dismisses the female of this species with the remark that 
it is “similar to the male;”! but as a matter of fact it differs very notice- 
ably in having the black of the forehead and lores replaced by pale 
ochraceous brown mixed with white, that of the subocular and auricu- 
lar regions by dull brown. The crown is also duller, the breastband 


' Cat. Birds Brit. Mus., XXIV, 1896, p. 228. 


NO. 1195. BIRDS FROM CENTRAL ASIA—OBERHOLSER. 207 


paler, the collar on hind neck narrower and less well defined. The 
young bird resembles the adult female, but is darker brown above, with 
buffy ochraceous margins to all the feathers; there is also more buffy 
on the sides of the head, the breastband is paler, and the entire lower 
surface, with the exception of the crissum, is more or less tinged with 
buffy. . 

Careful comparisons with the type of Dr. Richmond’s Wgialitis 
pamirensis prove beyond a doubt that it is the same as the bird Dr. 
Sharpe identifies! as pyrrhothorax of Gould. When Dr. Richmond 
described his pamirensis he had not access to the volume of the British 
Museum Catalogue containing the Limicole; and the species is synon- 
ymized with mongolus in Seebohm’s Geographical Distribution of Plo- 
vers, Sandpipers, and Snipes. Since no specimens of pyrrhothorax at 
that time existed in the United States National Museum collection, 
the mistake was of course a very natural one. The correct specific 
name of this species seems to be inconspicuus Wagler,’ the description 
and probable locality pointing to this identification, and this name 
antedating pyrrhothorax Gould by eight years. 


Family SCOLOPACID.. 
GALLINAGO SOLITARIA Hodgson. 


Gallinago solitaria HopGson, Gleanings in Science, ITI, 1831, p. 238. 

One male of this handsome snipe was taken on December 10, 1895, 
in the Valley of Cashmere. “Iris dark brown; bill plumbeous, tip 
black; feet and legs pale yellowish green; toes black. Length, 124 
inches.” 

HELODROMAS OCHROPUS (Linnzus). 


Tringa.ocrophus (err. typ.) LINN&%US, Syst. Nat., 10th ed., I, 1758, p. 149. 
Totanus ochropus TEMMINCK, Man. d’Orn., 1815, p. 420. 
One specimen in winter plumage, from the Valley of Cashmere. 
“Tris dark brown; feet and legs olive plumbeous; claws black; bill 
black, olive at base. Length, 94 inches.” 


TOTANUS TOTANUS EURHINUS, new subspecies. 


Chars. subsp.—Like true Totanus totanus, but very much larger. 

Description.—Type, male, adult, Cat. No. 162823, U.S.N.M.; Lake 
Tsomoriri, Ladak, 15,000 feet, July 29, 1897; Dr. W. L. Abbott. Above 
rufescent broccoli brown, the feathers everywhere with dark brown 
centers, the back more or less irregularly barred with the same; rump 
pure white, sparingly marked with brownish; tail and upper tail- 
coverts dull white, heavily barred with sepia brown, the terminal

portion of central tail-feathers buffy; wings fuscous, the innermost 
secondaries like the back and barred on exposed portions with dark 
brown; remainder of secondaries white, but pale brown on concealed 
bases; greater coverts white or grayish distally, brownish gray basally, 
and barred with sepia; median coverts brownish gray, barred with 
sepia; lesser coverts almost plain; lower surface white, more or less 
heavily marked throughout with sepia, these markings taking on throat 
and breast the form of broad streaks, on flanks, sides, and crissum of 
bars, and elsewhere of more or less irregular spots; lining of wing white, 
varied with brownish, except on axillars. 

The form of Totanus totanus' inhabiting Central and Eastern Asia, 
although seemingly identical with the European bird in color and mark- 
ings, is yet so much larger, particularly in length of wing, tail, and eul- 
men, that its separation as a subspecies appears to be warranted. All 
of the many names which the species possesses are without doubt exelu- 
sively applicable to the European bird, thus leaving the Eastern form 
without a name. The following table of millimeter measurements 
presents the difference between the two races:

Common about villages and cultivation [Gya]; common throughout 
Rupshu up to 16,000 and 17,000 feet. It comes picking around the 
camps and sheepfolds of the Champas.” These examples are identical 
with others from Cashmere and the Thian Shan Mountains previously 
obtained by Dr. Abbott, and recorded by Dr. Richmond as true 
rupestris.' They are, however, undoubtedly referable to Columba r. 
pallida, exhibiting all the characteristics of that race.

GYPS HIMALAYENSIS Hume 


Gyps himalayensis HUME, Rough Notes, I, 1869, p. 14. 


Two specimens accompanied by the following data. 

‘Male, Lolab, Cashmere, November 3, 1895; 8,000 feet. Iris mottled 
brownish gray; bill pale greenish horn; cere dark gray horn; bare skin 
on throat pale blue; feet pale greenish; claws blackish. Length, 463 
inches; extent, 110 inches; weight, 21 pounds.” 

‘‘ Female, Sind Valley, Cashmere, December 13, 1895; 6,000 feet. Iris 
dark brown; bill pale greenish horny (like jade); cere horny blachish 
brown; bare skin of head pale blue; feet pale greenish slate color; 
claws black. Length, 46 inches; extent, 107 inches; weight, 19 
pounds.” 

The male seems to be adult, although the crop patch is quite dark 
brown instead of whitish fawn color; the female, judging from the 
darker colors on the upper parts, appears to be more or less immature. 


Family FALCONID A. 
CERCHNEIS TINNUNCULA INTERSTINCTA (McClelland). 


Falco interstinctus MCCLELLAND, Proc. Zool. Soc. Lond., 1839, p. 154. 


Two adult males of this handsome falcon: one from Zogila Pass, 
Cashmere, at 10,500 feet; the other from Machalung, Indus Valley, 
Ladak. The latter specimen is a bird in process of molt (September 
17). ‘Its stomach contained lizards.” 

Specimens of the kestrel from Cashmere and Ladak are much darker, 
particularly above, than those from Europe, and should apparently bear 
the subspecific name interstincta McClelland. This race was originally 
described from specimens obtained in Assam, and it undoubtedly occu-

pies at least the whole of the Himalaya region, with very probably a 
large part of India. Birds from the Thian Shan Mountains and east- 
ern Turkestan are, however, paler, and apparently must be referred to 
the European form. 


FALCO PEREGRINUS Tunstall. 


Faleo peregrinus TUNSTALL, Orn. Brit., 1771, p. 1. 


Three specimens, all from the Valley of Cashmere. “Iris dark 
brown; bill horny blue, black at tip, greenish yellow at base; cere and 
eyelids yellow; feet yellow; claws black. Length of male, 16} inches; 
of female, 184 inches; weight of female, 25 pounds. Crop and stomach 
of latter contained the remains of a teal.” 

One of these examples, which is apparently not quite adult, is 
darker above than the others, with the markings below larger as well 
as more numerous, and with a conspicuous tinge of ochraceous on the 
abdomen. There seems to be little or no difference between similar 
plumages of the birds from Asia and Europe. Our limited materia 
indicates that European specimens are less bluish above and darker on 
the head; but this distinction very possibly would not prove constant 
in a larger series. 

The Falco peregrinus of Tunstall, as above quoted, is apparently the 
earliest available name for the peregrine falecn, being 17 years prior 
to Gmelin’s names. Most of the new specific designations in Tunstall’s 
Ornithologica Britannica are mere nomina nuda, but some, among 
them Falco peregrinus, have references to Pennant’s British Zoology, 
and are thus rendered tenable. 


MILVUS GOVINDA Sykes. 


Milvus govinda SyKEs, Proe. Zool. Soc. Lond., 1832, p. 81. 


One adult male from the Valley of Cashmere, December 4, 1895. 
“Iris brown; bill black, horny blue at base; cere pale horny; feet 
dirty white; claws black. Length, 244 inches.” 


HALIAZETUS LEUCORYPHUS (Pallas). 


Aquila leucorypha PALLAS, Reis. Russ. Reichs, J, 1771, p. 454. 
Haliaetos leucorypha KEYSERLING and Buiastus, Wirb. Eur., 1840, p. xxx. 

Two specimens; one of them a male from the Hanlé River, Rupshu, 
Ladak, taken September 2, 1897. ‘‘Length,505 inches. Poisoned while 
feeding on the dead careass of a wild ass (Kiang).” The other example 
is a female from Woolar Lake, Vale of Cashmere, September 16, 1895. 
“Tris brownish gray; bill dull black; cere and base of bill grayish 
white; feet dirty white; claws black. Length, 314 inches. Feeds on 
dead fish and carrion; foully dirty.” 

The plumage of the female has much ochraceous, the tips and edges 
of the feathers everywhere being more or less tinged with either this 


BMP PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXII. 


color or fulvous, darkest on the head and neck. The breast and abdo- 
men are quite uniform ochraceous, the throat darker, more fulvous, the 
erissum more brownish; the tail is almost plain blackish brown, mot- 
tled somewhat with grayish near its base. The male is far from being 
so deeply ochraceous above, the edgings on the feathers of back and 
wings being whitish or buffy, producing a curiously mottled appear- 
ance, and forming thus a conspicuous contrast to the plumage of the 
female. Below the color is pale dull brownish, lighter and more ochra- 
ceous on the abdomen and foreneck, darkest on the throat; tail black, 
slightly tipped with whitish, and with a broad ill- defined nee of rife 
gray and dull white across Hg middle portion. 


HALIZZETUS ALBICILLUS (Linnzus). 


Falco albicilla Linnaus, Syst. Nat., 10th ed., I, 1758, p. 89. 
Haliwetus albicilla LEacu, Syst. Cat. M. B. Brit. Mus., 1816, p.9. 

‘Iwo specimens, both taken in the Vailey of Cashmere, on December 
19, 1895. ‘Male: Iris straw color; feet yellow; claws black. Length, 
324 inches; weight, 8 pounds. Stomach contained remains of a green 
woodpecker (Gecinus squamatus). Female: Iris straw color; bill and 
‘cere horny yellow; feet yellow; claws black. Length, 343 inches; 
weight, 10 pounds. Crop contained a thrush (Jerula); stomach con- 
tained remains of thrushes and rats.” 

Both of these specimens seem to be fully adult, their tails white ds. 
tally, except for small dusky markings near ake ends of the feathers. 
The many light tips, and some altogether paler feathers on both upper 
and lower parts, give to the plumage in places a conspicuously mottled 
appearance. These individuals appear to be perfectly identical with 
one from Korea. 


AQUILA BIFASCIATA J, E. Gray. 


Aquila bifasciata J. E. Gray, Hus. Ind. Zool., I, 1832, pl. x v1. 


Three specimens, all females, taken in the Valley of Cashmere, 
December 20 and 22, 1895. “Iris dark brown; bill horny blue, tip 
black; gape, cere, and feet yellow; claws black. Length, 31-32 inches; 
weight, 74 pounds. This species is very common in the valley at this 
season, and is very tame, sitting on the trees in the villages, probably 
because rats are plentiful near the houses. The stomachs of two of 
the birds taken contained remains of Mus rattus.” 

Two of the present examples are apparently typical adults, one of 
them evidently in process of molt both above and below. The remain- 
ing specimen is seemingly immature, being darker than the others, 
particularly on scapulars, wing-coverts, head, and under surface, while 
the primary-coverts as well as the greater series lack any indication of 
the paler tips characteristic of the adult. In this condition Aquila 
bifasciata superficially much resembles A. chrysaétos, but is everywhere 
paler; has fewer light fulvous feathers on occiput and nape; and the 


No. 1195. BIRDS FROM CENTRAL ASTA—OBERHOLSER. 213 


light ashy bars on the tail extend throughout, not leaving a broad 
band of black at the tip. 

The present writer is quite inclined to agree with Dr. Sharpe in his 
identification ' of the present species with the Aquila mogilnik of S. G. 
Gmelin;? but it is perhaps better, particularly in view of the confusion 
existing through diversity of opinion, to abandon entirely the use of 
Gmelin’s name, simply considering it unrecognizable—the course so 
strongly urged by Mr. Blanford.? The proper name for the steppe

black. Length, 32 inches; weight, 8} pounds. Crop and stomach filled 
with the remains of Mus rattus. 

‘Female adult: Iris gray, mottled with brown; bill horny blue, tip 
black; cere dull horny yellow; feet pale dirty yellow; claws black. 
Length, 324 inches; weight, 94 pounds. Stomach contained remains of 
mongoose (Herpestes auropunctatus). 

“Immature [sex not given, but probably male]: Iris straw color, 
mottled with brown on lower half; bill horny blue, black at the tips; 
cere horny white, with a greenish tinge; toes pale yellow; claws black. 
Length, 31 inches; weight, 54 pounds. 

‘‘Kemale immature: Iris brownish gray; bill horny blue, the tip 
black; cere horny yellow; feet yellow; claws black. Length, 31? inches; 
weight, 7 pounds. Stomach contained remains of a grebe (Podiceps).” 

In the two immature birds the dark streaking below is confined to 
the jugulum, breast, and upper abdomen; in the supposed male it is 
quite narrow, but in the female is so broad as to be in many places 
confluent.

weight, 3 pounds. Stomach contained a mouse.” 

The changes of plumage in this species are not a little puzzling. 


No. 1195. BIRDS FROM CENTRAL ASTA—OBERHOLSER. Dalek 


There seem to be, however, four principal phases: One in which the 
lower parts are very light colored, with little or no rufous, and with 
comparatively inconspicuous streaking; another, in which the under 
surface has more rufous, is much streaked anteriorly and barred or 
mottled posteriorly; a third, in which the entire lower surface is almost 
without obvious streakings, being rufous on throat and breast and dull 
brown on the hinder portions; and a fourth, in which the whole plumage 
above and below is almost uniform sooty brown. Connecting these sev- 
eral places there exists an almost unbroken series of intermediates. 
Doctor Sharpe considers that the last-mentioned condition is the very 
old bird,! and that each individual is very light when young, gradually 
darkening with advancing years. The present series of specimens 
offers much to corroborate this theory, and very little, if indeed any- 
thing, tooppose. The birds in the first of the above-mentioned phases, 
are without any doubt very young, and those of the last two are just 
as unquestionably adults. Those uf the second phase are not so satis- 
factorily determinable, but they seem to be in a transition state, although 
how many years are required to assume this plumage must still, of 
course, be a matter of conjecture. Were any of the darkest specimens 
young birds they would easily establish a case of dimorphism very 
similar to that of the American Buteo swainsoni, to which, in its various 
phases of plumage, the present species bears no slight resemblance. 
Without such examples, however, it seems premature to advance this 
hypothesis as more than a suggestion, and in the light of our present 
knowledge we must regard the various differences of plumage as the 
result of age. Only one individual of this series has a completely red 
tail, though several have a greater or less tinge of rufous. The old 
adults, as also the very young birds, appear not to have a rufous tail; 
so that unless we are in error as to the sequence of plumage, the rufous 
tail belongs, rather curiously, to a transition stage. 

In some conditions of plumage the present species is very difficult 
to distinguish from Buteo desertorum, but the larger size of the former 
will usually serve for identification.

Two examples. One is an adult male from Sind Valley, Cashmere, 
at 6,000 feet altitude, taken December 14, 1895: ‘Iris and feet yellow; 
claws black; bill black, the base horny blue. Length, 134 inches.” The 
other is an immature female from Srinagar, Cashmere, December 30, 
1895: “Tris yellow; bill black, horny blue at base; cere yellowish green; 
feet yellow with a tinge of green on tarsus; claws black. Length, 153 
inches. Stomach contained the remains of small birds. This hawk was 
pursuing a jackdaw when shot.”

The male is in fully adult plumage, and the rufous bars on the breast 
are so broad as to be in places confluent. It is darker above than a 
specimen from Egypt, but the present series indicates this difference 
to be individual rather than geographical.

CALANDRELLA ACUTIROSTRIS Hume. 


Calandrella acutirostris HUME, Lahore to Yarkand, 1873, p. 265. 


Two specimens, from Bazgo plain, Ladak, 11,000 feet. “Tris dark 
brown; bill dark horn-brown above, yellowish at base beneath; feet 
brownish fleshy; claws pale horn-brown. Common on this plain, in 
pairs.” These examples are identical with those previously collected 
by Dr. Abbott in Ladak and Tagdumbash Pamir but recorded by Dr. 
Richmond as tibetana.' 

From Calandrella brachydactyla and dukhunensis both acutirostris and 
tibetana may readily be distinguished by the absence of deep buffy 
tinge in the edgings of the exterior webs of the outermost tail-feathers. 
Aside from the shape of the bill, a differential character apparently 
quite unreliable by reason of the great range of individual variation, 
tibetana may be separated from acutirostris by the pattern of the outer 
pair of tail-feathers. In the former species the whole feather is white 
excepting the basal third of the inner web and the extreme base of the 
outer, which are obliquely blackish; in acutirostris the inner web of 
the outer tail-feathers is largely blackish, the white occupying a diago- 
nally terminal area equal to only about a fourth of the inner vane 
and one-half the outer. Dr. Richmond’s inability satisfactorily to dis- 
tinguish from tibetana the specimens he records as acutirostris® is 
explained by the fact that he had no examples of tibetana, those with 
which he made his comparison as such being all acutirostris. 


ALAUDA ARVENSIS LEIOPUS (Hume). 
Alauda leiopus HUME, Stray Feathers, I, November, 1872, p. 40. 


Two breeding males from Shooshot, Indus Valley, Ladak, at 10,000 
feet. Dr. Abbott reports them as “very common in the cultivated 
fields.” These specimens do not differ from those obtained by Dr. 
Abbott in Cashmere. 

Owing to the unfortunate confusion which at present exists among 
the races of Alauda arvensis, any determination must of necessity be 
largely tentative; but so far as our series is indicative, the birds from 
eastern Asia are larger and have more slender bills than those from 
Cashmere and Ladak, the difference being apparently sufficient to war- 
rant subspecific separation. Dr. Richmond used the name Alauda

arvensis intermedia (Swinhoe)' for this race, considering it not to differ 
from the bird of eastern Asia, but stating that in the event of their sep- 
aration the name guttata of Brooks would be the proper one for the 
Cashmere form, since Alauda leiopus of Hodgson’? is a nomen nudum. 
Mr. Hume, however, in an article on the skylarks of India differenti- 
ates “the Leiopus type from Ladak, Thibet, and the higher Himalayan 
plateau generally ;”* giving a diagnosis, and identifying his bird—which 
he regards as the breeding form of the region mentioned—with leiopus 
of Hodgson. As Hume’s name antedates A. guttata of Brooks, and 
since it is a perfectly tenable one, notwithstanding the unavailability 
of A. letopus Hodgson, the skylark of Cashmere and Ladak should be 
called Alauda arvensis leiopus (Hume).

Accentor altaicus BRANDT, Bull. Acad. St. Pétersb., I, 1843, p. 365. 

One young male, from Mya, on the Indus River, Ladak, at 13,000 
feet. 

This bird is in first plumage, though wings and tail are full grown, 
and may be described as follows: Upper surface dull buffy ochraceous, 
rather more ashy on nape, darker on back; everywhere, except on 
upper tail-coverts, mottled with darker, these markings largest on 
back, duller and smaller on head and hind neck; tail fuscous, edged 
externally with chestnut; wings fuscous, with broad margins of chest- 
nut, the wing-coverts tipped with ochraceous; sides of head and neck 
dull brown mixed with ochraceous; a poorly indicated superciliary 
stripe of butty; chin buff, speckled with dusky; throat pale dull buff, 
thickly marked with blackish; breast and jugulum deep ochraceous, 
streaked with blackish; remainder of under surface plain buffy. 
* Length, 64 inches.” 

Though commonly known as Accentor altaicus, there seems to be no 
reason why the earliest name for this bird, Accentor himalayanus Blyth, 
should not be employed, since the original description is clearly perti- 
nent enough to be tenable.

One adult male from Kargil, Ladak, taken June 23, 1897, at 8,000 feet, 
altitude. ‘Bill and feet black.” This bird is in rather worn plumage, 
particularly on the head, but is apparently quite a typical specimen. 
Intergradation with true picata makes necessary the trinomial desig- 
nation here employed.

Rupshu, at 16,000 feet, and all are in worn condition. An October male 
from Nurla, in the Indus Valley, at 10,000 feet, is in freshly molted 
plumage, and, besides having the black areas obscured by light tips to 
the feathers, is elsewhere on the body strongly tinged with isabella 
color, this particularly evident on the lower back, upper tail-coverts,

and under surface. Two of the three breeding females are from Gya, at 
13,000 and 15,000 feet, respectively, and though in every other respect 
typical, have the throat and sides of the neck, not including the chin, 
dull brownish black, somewhat mixed with buffy, instead of the ordi- 
nary dull buffy. The third female is from Tsokr Chumo Lake, at 15,000 
feet altitude; the collector’s note on the label, “bill, feet, and claws 
black,” is applicable to both males and females. 

The name Savicola montana Gould, currently used for this stone chat, 
is preoccupied by Saxicola montana Koch,' which is Monticola saxratilis 
Linnzeus; and as there are no synonyms, the new name above given 
becomes necessary.

One specimen from Leh, Ladak, 11,000 feet. ‘‘ Length, 48 inches.” 
This is a fall bird, differing from a similar example from the Thian 
Shan Mountains in being more brownish on the head, rump, and under 
parts, this probably an indication of immaturity.

One example, September 11, 1897, from Mya, Indus River, at 12,500 
feet, is probably a bird of the year. The entire body plumage is 
noticably paler than in two breeding birds from Cashmere.

One example, from the Sind River, Cashmere, taken at 6,000 feet. 
“Length, 83 inches.” Not in any way different from Ladak specimens. 

The name Cinclus asiaticus Swainson, as above cited, is a nomen 
nudum; but as there remains some doubt about the proper designation 
of the species, no change is here made.

One specimen, from Gya, Ladak, at 13,000 feet. ‘Front of tarsi and 
top of toes lead color, rest of feet dull black; bill black. Length, 8

Specimens, and the feathers of the flanks and sides lack entirely the 
whitish edgings of the latter season.

Two specimens from Lamayuru, Ladak, taken June 26, 1897, at 12,060 
feet altitude. ‘‘ Bill black, leaden beneath at base; feet pale fleshy 
brown, with a reddish tinge; claws dark horn brown.—Common on the 
bare stony hillsides and about villages up to 13,000 feet; always in pairs 
at this season.” 

These birds are typical cia, not stracheyi, which Dr. Richmond sur- 
mised! to be the breeding form of the region.

Two breeding specimens from Upshi, Valley of the Indus, Ladak, at 
11,000 feet. “Iris brown; bill pale brownish horny above, whitish 
horny beneath; feet in male black, in female dark fleshy brown.” Dr. 
Abbott notes that he found the species “in pairs on the stony hillsides.”

One male from Tashgam, Ladak. “Iris brown; upper mandible 
horny brown, lower mandible dull yellowish horny; feet fleshy brown; 
claws horn brown.” 

From the specimens available it is indicated that the birds of this 
region are entitled to subspecific recognition by reason of their decidedly 
brighter colors; but this material is too - meager to justify a formal 
separation.

These specimens agree perfectly with other adults, except that the 
bright patch on the forehead is orange instead of scarlet, a condition 
very probably due to the abrasion incident to the breeding season.

One specimen from The Lolab, Cashmere. ‘Feet brownish black; 
iris pale brown.” 

An examination of the original description of Eversmann’s Fringilla 
altaica, which Dr. Sharpe stated! that he was unable to discover, proves 
beyond a doubt what was long ago affirmed by Severtzoff *— the priority 
of the name altaica for the species commonly called Montifringilla sor- 
dida (Stoliczka). Eversmann gives the southern Altai Mountains, 
“ Umgegend des Dorfes Uimon” as the locality; and his diagnosis is as 
follows: ‘ . rostro crasso conico; gastrwo fusco-cinereo, concolore; notco 
fusco-liturato, capite ferruginoso; rectricibus nigricantibus concoloribus. 
tectricibus caude superioribus apice lato albo.” Mention also is made of 
affinity to Leucosticte arctoa and Fringilla montifringilla.

LINARIA BREVIROSTRIS PYGMEA (Stoliczka). 


Linota pygmea STOLICZKA, Journ. As. Soc. Bengal, XX XVII, Pt. 2, 1868, p. 62. 


Five summer birds from Gya, Ladak, at from 13,000 to 14,000 feet. 
According to Dr. Abbott’s notes the color of the feet ranges from 
‘dark fleshy brown” to black; and the bill is variously “ pale brown- 
ish fleshy,” ‘dull leaden,” or ‘“‘horny white,” always “ dark brown at 
tip.” “Length, male, 53 inches.” With regard to their habits he states: 
“In small flocks about the patches of cultivation and picking among 
the horse.droppings in the road.” 

These five specimens are exceedingly interesting, since they estab- 
lish beyond a doubt the validity of Linota pygmca Stoliczka, a form 
which has heretofore always been synonymized with JL. brevirostris.. 
Even casual comparison is sufficient to show that the two are at least 
subspecifically distinct. The original specimens of pygmea came from 
Chini and Padam, so that this form seems to be confined chiefly to 
Ladak; L. brevirostris apparently occupying the region extending from 
Asia Minor to Turkestan. The original wing measurement is smaller 
than that of the present examples, but, excepting this and a few other 
unimportant discrepancies, the original description of Linota pygmcea is 
perfectly applicable. 

From Turkestan and Tagdumbash Pamir specimens, which are 
assumed to be nearly or quite typical brevirostris, pygmea differs in 
being much darker, more fulvous throughout, this being most evident 
on jugulum, breast, and back. One individual is rather paler than the 
others, thus in a measure verging toward brevirostris and indicating 
its subspecific relationship, but is without difficulty distinguishable. 

The proper generic name for the linnets is apparently Linaria Bech- | 
stein,! this being almost thirty years prior to to Linota Bonaparte? which 
has been in frequent use for the group. Dr. Sclater, after showing 
Linaria to be the earliest name,* rejects it on account of previous 
employment in botany,* a course not in accord with current usage.

One adult male, December 16, 1895, from Sind Valley, Cashmere, at

tinge of the lower surface. ‘Bill horny yellow, brown at tip; feet 
pale brownish flesh color. Length, 74 inches.”

bill green, slightly yellowish. Length, 9 inches.” 

The generic term Pycnorhamphus Hume,’ commonly applied to this 
and two allied species, is preoccupied by Picnoramphus Rosenberg,* a 
synomym of Sphecothera Vieillot, the difference in the spelling of the 
two names being simply one of transliteration. Since for Pycnorham- 
phus there is no other name available, it may be called as above—Peris- 
sospiza, from zepiooos, mirabilis, and ozita, fringilla. The remaining 
species of this genus will consequently stand as Perissospiza affinis

One specimen, June 29, 1897, from Spittak, Indus Valley, Ladak, at 
10,000 feet. ‘‘Feet pale brownish fleshy; iris blackish brown; claws 
horn brown; bill dull black.” With a fair series of both Asiatic and 
European specimens at hand, no difference worthy of subspecific recog- 
nition is apparent. 

The generic term Biblis,’ commonly applied to the crag martins when 
they are distinguished from Riparia (=Cotile), is ineligible for use in 
this connection, being preoccupied in Lepidoptera by Biblis Fabricius.® 
The next available name is Ptyonoprogne Reichenbach,’ which should 
therefore stand as the proper designation of the group.

which was nesting in a bluff of conglomerate on the banks of the Indus.

generically distinct from C. urbica and its allies, the generic name 
Delichon must be used for all. The only alternative is to restrict Deli-

NOTES ON SOME BIRDS FROM SANTA BARBARA ISLANDS, 
CALIFORNIA. 


By HARRY C. OBERHOLSER, 


Assistant Biologist, Department of Agriculture. 


During the spring and summer of 1892, Mr. Clark P. Streator, under 
the auspices of the Biological Survey of the Department of Agricul- 
ture, made a small collection of birds upon the Santa Barbara Islands, 
California. Of these specimens, which are now in the United States 
National Museum as part of the Biological Survey collection, the 
writer has been able, through the kindness of Dr. C. Hart Merriam, 
to prepare the subjoined list. The new forms obtained by Mr. Streator 
have already been described; so it remains only to record the species 
collected, with the addition of various critical notes upon those of 
special interest. 

The islands visited by Mr. Streator, with inclusive dates of his col- 
lecting, are as follows: 

Santa Catalina Island, April 9 to 29. 

San Miguel Island, June 24 to 29. 

Santa Rosa Island, July 1 to 3. 

Santa Cruz Island, July 9 to 20. 


PUFFINUS GRISEUS (Gmelin). 


A single specimen, taken July 3, in the Santa Barbara Channel, is 
in the collection. 


LOPHORTYX CALIFORNICUS VALLICOLA (Ridgway). 


One male and one female from Santa Catalina Island. They seem 
rather darker and more ochraceous than extreme examples of vallicola, 
but are identical with birds from the San Joaquin Valley. The species 
has probably been introduced from the mainland. 


COLAPTES CAFER (Gmelin). 


An immature specimen from Santa Cruz Island apparently does not 
differ from birds of the adjacent mainland, though the material at hand 
for comparison is not entirely satisfactory.

Two adult males in perfect plumage, from Santa Catalina Island are 
identical with Nicasio birds. 


SAYORNIS NIGRICANS (Swainson). 


Three birds from Santa Cruz Island are all immature, with rufous 
edgings to the feathers of lower back, under wing-coverts and all the 
upper series; the innermost secondaries are also margined with a paler 
shade of the same. Two adults taken on Santa THOSE Island add the 
species to the fauna of this island. 


EMPIDONAX INSULICOLA Oberholser. 


Five specimens; from Santa Rosa, Santa Cruz, and Santa Catalina 
islands; all mentioned in the original description of the species.! Since 

that was published, the writer, through the courtesy of Mr. Joseph 
_ Grinnell, has examined specimens from San Clemente Island, which are 
substantially identical with those from the other islands. 


OTOCORIS ALPESTRIS INSULARIS Townsend. 


Twelve examples from San Miguel Island and one from Santa Rosa 
are all in more or less worn plumage, but even in this condition exhibit 
the distinctive characteristics of this insular race. 


APHELOCOMA INSULARIS Henshaw. 


A fine series of twelve adults and five immature specimens serves 
very strongly to emphasize the distinctness of this species from both 
of its mainland relatives. Not only areits characters very pronounced, 
but among perfectly comparable examples there is relatively little 
individual difference either in size or color. Many of the adults are 
strongly tinged with brownish below, but this is undoubtedly an 
adventitious stain, as it is absent on feathers of the fresh plumage. 
All the adults are in process of molt and exhibit almost every stage 
of feather renewal. The immature birds are all in “ first” plumage, 
just beginning to change into perfect dress, and differ little from each 
other. The plumage of the young, which seems never to have been 
described, is as follows: 

Above chocolate brown, shading into dull dark blue on crown and 
upper tail-coverts, the transition on latter rather abrupt; wings and 
tail as in the adult; sides of head and neck blackish brown; a short 
' whitish line over each eye, the only indication of a superciliary; chin, 
throat, and center of jugulum brownish white, the sides of jugulum 
and an almost complete collar on breast dull blackish brown; remainder 
of breast and abdomen smoke gray; crissum dark slate gray; thighs 
light brown.

CORVUS CORAX SINUATUS (Wagler). 


One individual from Santa Catalina Island appears to be indistin- 
guishable from typical specimens. 


STURNELLA NEGLECTA Audubon. 


Two specimens from San Miguel Island, one of them a female in the 
spotted and mottled plumage of the young. The other, an adult male in 
rather worn condition, seems not to differ from neglecta of the mainland. 

It seems remarkable that anyone who has ever heard the striking 
vocal performances of the western meadowlark should consider it a 
subspecies of the eastern bird. And when there is taken into account 
the fact that over a large area the breeding ranges of the two overlap, 
the birds there remaining as distinct as elsewhere, and that the sup- 
posed intermediate specimens ultimately resolve themselves into sea- 
sonal or some other equally nonpertinent variation, the rational course 
would appear to be the recognition of Sturnella neglecta as a full species. 


CARPODACUS MEXICANUS CLEMENTIS (Mearns). 


Fourteen specimens, from Santa Catalina, San Miguel, and Santa 
Cruz islands, are referable to this new race. The males differ much 
among themselves in the shade of the red on throat and breast, as well 
as in the extent and intensity of the red suffusion on the anterior upper 
surface, in some individuals this color being confined almost entirely to 
the crown. There is also a considerable range of variation in dimen- 
sions, inclusive of the bill, size being but an average subspecific dis- 
eae The specimens examined are darker above than obscurus 

= frontalis),' a SINE OEE not mentioned by Dr. Mearns in his original 
ae 2 

Birds in the juvenal eannace. are much more ochraceous, particularly 
above, than adult females, and seem to be rather darker than the young 
of obscurus. This plumage of clementis appears not to have been 
described, and the following is therefore added, from a male shot on 
Santa Ona Island, July 18: 

Above dull brown, rather darker on the back, all the feathers with 
ochraceous margins, these imparting a somewhat streaked appearance; 
rump and upper tail-coverts almost plain deep ochraceous; wings and 
tail fuscous, edged with buffy, the wing-coverts and innermost second- 
aries margined with ochraceous; lores and subocular region buffy 
whitish; sides of head and neck ochraceous, streaked with dull brown; 
under surface dull white, washed with ochraceous and everywhere 
streaked with dull brown; crissum buffy ochraceous, with narrow shaft 
markings of brown.

ZONOTRICHIA LEUCOPHRYS GAMBELI (Nuttall). 


A paie of adults from Santa Catalina Island. This is the race for- 
merly known as intermedia." 


SPIZELLA SOCIALIS ARIZONZ® Coues. 


Three specimens. Two of these are adults from Santa Catalina 
Island, and are in color and in most of their measurements apparently 
like the mainland form. The wings are, however, somewhat shorter, 
but the difference seems too slight to warrant the separation of the 
island bird. The third specimen, which is in the spotted plumage of 
the young, is from Santa Rosa, and appears to be the first record of the 
species for this island. 


MELOSPIZA MELODIA CLEMENT (Townsend). 


Kighteen specimens, including both adults and young, from the 


islands of San Miguel and Santa Rosa. The adults are in worn pluin-— 


age, but agree with examples from San Clemente Island, the type 
locality of this race. The young exbibit much more individual varia- 
tion than the adults, but on the whole present quite as good characters 
for subspecific distinction. This juvenal stage, as is usual among the 
song sparrows, is quite different in appearance from the adult, and may 
be described as follows: 

Above brownish gray, somewhat rufescent on the rump, the feathers 
with deep brown or blackish centers, these broadest on back, where 
they are margined conspicuously with pale grayish; head with no 
evident median stripe; wings and tail about as in the adult; sides of 
head and neck dull buffy white, considerably mixed with brown; 
lower parts dull buffy white; jugulum, sides of throat and body, with 
short streaks of brownish gray, less evident on the last. 

The species appears not to have been previously recorded from San 
Miguel Island. 


MELOSPIZA LINCOLNII (Audubon). 


A single adult female from Santa Catalina Island. The upper sur- 
face is rather more than usually tinged with ochraceous, as are also 
the posterior lower parts, thus almost obliterating the definition of the

PASSERELLA ILIACA STEPHENSI Anthony. 


Although not recorded from any of the islands of the Santa Barbara 
group, three specimens from Santa Catalina Island are undoubtedly 
referable to this race, being of course migrants from the mainland, as 
all the other forms of Passerella seem to be. Two of these individuals 
are quite typical, the other verging somewhat toward megarhyncha. 
All have a considerable tinge of brown over the entire upper surface. 


PIPILO MACULATUS CLEMENT 4 (Grinnell). 


Three examples from Santa Cruz Island, with one from Santa Rosa, 
are in color like clementce, but differ in their somewhat smaller size. A 
single bird in juvenal plumage is very little different from the similar 
stage of megalonyx. Seven adults from Santa Catalina Island are 
intermediate between clemente and the mainland coast form (P. m. 
atratus) recently described by Mr. Ridgway, but seem to be nearer the 
former. 


LANIUS LUDOVICIANUS ANTHONYI Mearns. 


A single specimen in juvenal plumage is darker above than even 
ludovicianus of similar age. 


HELMINTHOPHILA CELATA SORDIDA Townsend. 


Hight males and two females were collected, all on Santa Catalina 
Island. This fine series bears out the characters assigned by Mr. 
Townsend, but shows also that these differences are not entirely con- 
stant. The olivaceous wash on the flanks is one of the best distine- 
tions. 


MIMUS POLYGLOTTOS (Linnzus). 


Three exainples from Santa Catalina Island show considerable indi- 
vidual variation in the shade of the upper surface, but appear to be 
absolutely indistinguishable from birds of the extreme eastern United 
States. They are quite brownish both above and below, but this is 
evidently due to wear or stain, perhaps to both.

previous paper,' and therefore need not be repeated here.

Ten specimens, from Santa Cruz and Santa Rosa islands. Al! tnese 
were recorded in the writer’s recent paper on the genus.' Since the 
appearance of that article additional material from Santa Cruz Island 
has been examined, substantiating former conclusions with regard to 
the validity of this form. It is certainly different enough from both 
charienturus and drymecus to warrant recognition as a subspecies. 
Two young birds from Santa Rosa are somewhat paler above than the 
young from Santa Cruz Island.

CATALOGUE OF A COLLECTION OF BIRDS FROM MADA- 
GASCAR. 


By HARRY C. OBERHOLSER, 
Assistant Biologist, Department of Agriculture. 


During a period of some eighteen months, extending from July, 1894, 
to February, 1896, the Rev. James Wills formed a small collection of 
birds in Madagascar. He worked chiefly in Imerina, in the east central 
part of that island, most of the specimens coming from the various 
forests in the more or less immediate vicinity of that locality. These 
birds, numbering 110 and referable to 57 species, were eventually 
purchased by the United States National Museum. In the list which 
follows, the presence of the rare Lophotibis cristata and the little known 
Ardeola xanthopoda seems worthy of note. Pertinent remarks on the 
colors of the soft parts, which, whenever available, are added from the 
labels of the specimens, will be found between quotation marks

Gallinula chloropus pyrrhorrhoa SIBREF, Ibis, 1892, p. 114. 

One specimen, April, 1895, from ‘‘ between the two forests,” East 
Madagascar. 

The ochraceous crissum seems to warrant at least the subspecific 
separation of the Madagascan form of Gallinula chloropus, although the 
occasional presence of this character in the typical bird indicates the 
inadvisability of according pyrrhorrhoa specific rank.

Two specimens, seemingly male and female, though unsexed. The 
supposed female is of generally duller plumage than the male; the spots 
on neck, throat, jugulum, breast, flanks, and sides are larger and less 
sharply defined; the sides, together with the upper and lower tail 
coverts, lack almost entirely the wavy cross lines; and the inner sec-

ARDEOLA XANTHOPODA (Hartlaub). 


Ardea xanthopoda HARTLAUB, Journ. f. Orn., 1860, p. 166 (from the Pelzeln man- 
uscript). 

One adult specimen in breeding plumage, from ‘between the two 
forests,” East Madagascar, taken in September, 1894. 

Whether or not the present individual is identical with that men- 
tioned by Dr. Sharpe! as being different from Ardeola ide, but proba- 
bly the same as Garzetta garzetta, it is certainly not true Ardeola ide, 
nor can it by any means be referred to Garzetta garzetta, but it agrees 
perfectly with Hartlaub’s original description of Ardea xanthopoda.? 
It differs from Ardeola ide, with which it has heretofore generally been 
confounded, chiefly in being almost pure white; from Garzetta garzetta 
it may be distinguished by the following characters, several of which, 
it will be noticed, may be regarded as generic: Bill shorter and pro- 
portionately stouter, the black tip sharply defined from the light base; 
whole foot very much shorter, and yellowish, not black; plumes of 
breast entirely decomposed, not lanceolate; head and hind neck 
strongly suffused with ochraceous, not pure white. It is therefore 
evident that Dr. Sharpe has insufficient grounds for synonymizing 
Ardea xanthopoda with Garzetta garzetta,? Captain Shelley being con- 
sequently right in his opinion of its distinctness.* 

A description of this specimen is as follows: Entirely pure white, the 
head and cervix washed with ochraceous, this deepest on the forehead, 
gradually disappearing posteriorly; two of the innermost secondaries 
dull brown, their broad shaft stripes pale yellowish; a few black 
streaks on the sides of the occiput; ornamental plumes of wholly decom-

Dr. Richmond is apparently quite right in his view! that the yellow 
tips to the black feathers are not an evidence of immaturity, but simply 
the usual accompaniment of the fresh molt, wearing off by abrasion 
until the bird assumes a jet black appearance. 

The earliest name for the present species is Turdus castaneus Miller, 
which antedates Turdus jala Boddaert by five years; and there seems 
to be no reason why it should not be adopted, as has already been done 
by Dr. Richmond.’

The only character adduced by Dr. Sharpe? for the differentiation of 
Ixocincla from Hypsipetes is the tarsal scutellation, a distinction which 
examination of a series of perfect specimens does not sustain, in so far 
at least as is concerned comparison of the present species with psaroides, 
the type of Hypsipetes. Whatever may be the affinities of the other 
forms, with which we at present have nothing to do, psaroides and

The single specimen referred to this species agrees in most respects 
with Dr. Sharpe’s description of the very young bird,' except that the 
breast has no admixture of rufous feathers. The shade of the entire 
upper parts, including wings and tail, is a much less rufescent olive 
than in the adult. Judging from the texture of the plumage, however, 
this individual does not seem to be a very young bird.

Cisticola cherina SHARPE, Layard’s Birds S. Afr., 1876, p. 278. 
One example from Imerina. It is apparently an adult, and isin the 
plase having a uniform crown; the lower surface is almost without 
yellow tinge.

Muscicapa mutata LINNZUS, Syst. Nat., 12th ed., I, 1766, p. 325. 
Tehitrea mutata GRAY, Genera Birds, I, 1846, p. 259. 

Three specimens from East Imerina. One of these is a male just 
assuming the plumage of the adult, the tail being white and black, the 
lower parts mixed white and rufous. The two other individuals are 
young males, one in the rufous plumage of the female, the second in the 
dark, rich chestnut garb. 

The generic name Terpsiphone, currently employed for the group of 
flycatchers to which the present species belongs, was originally pro- 
posed by Gloger' as a substitute for Muscipeta Cuvier,’ because Musci- 
peta was considered “zu iihnlich und ganz gleich bedeutend mit 
Muscicapa;” and since the type of Muscipeta is the South American 
Todus regius Gmelin (= Muscivora regia auct.), it follows that the same 
Species must be regarded as the type of Terpsiphone. This being the 
case, Terpsiphone can of course not be used to designate the Old World 
genus, for which the name Tchitrea Lesson * then becomes available.

Two examples of this rare species are in the collection. The points 
of difference from Newtonia brunneicauda given by Dr. Reichenow are 
fully sustained by the two adult specimens in the National Museum; 
and, in addition, amphichroa seems to have a somewhat larger bill. 

One of the present examples is in first plumage, and may be described 
as follows: Crown, nape, and rump chestnut; back olive brown, tinged

sex in being nearly uniform grayish olive green above, with only a few 
scattered metallic feathers; sides of head and neck dull olive grayish, 
mixed with pale yellowish; throat dull black; crissum yellowish white; 
remainder of lower parts bright yellow, the sides washed with olive.

Two specimens from the forest of East Imerina are identical with 
those collected by Dr. Abbott. The earliest name for the present spe- 
cies, which is commonly known as Zosterops madagascariensis, seems to

strongly washed with brownish, the remaining lower parts slightly so; 
the innermost secondaries are conspicuously tipped with white; the 
primaries and secondaries are distally margined on exterior webs with 
buffy. One of these birds differs from the other in having an almost 
black nuchal collar, and, though in other respects resembling the 
female, is apparently a male. This individual has the greater wing- 
coverts tipped and exteriorly edged with buffy white. ‘Iris dark

In the female of this species the brilliant metallic blue of the exterior 
webs of the wing-quills is replaced on the primaries by green, on the 
secondaries by brown with a marginal and distal greenish gloss; and 
the white of the wing is very much reduced in extent. 

The specific term auratus of Miiller seems to be the earliest one for 
the species, having seven years priority over madagascariensis Bod- 
daert'; and, since it seems to be eligible, should be given the preference, 
as has already been done by Dr. Richmond in the article previously 
cited.

REPORT ON A COLLECTION OF DIPTEROUS INSECTS 
; FROM PUERTO RICO. 


By D. W. CoQuiLLEtTt, 
Custodian of the Diptera in the U. S. National Museum. 


During the months of January and February, 1899, Mr. August 
Busck, of the U.S. Department of Agriculture, through the courtesy 
‘of the U.S. Fish Commission, visited various portions of Puerto Rico, 
and among other things collected quite a large series of dipterous 
insects, which were later deposited in the U. S. National Museum. 
This series comprises 864 specimens, representing 117 species, distrib- 
uted in 79 genera and 31 families. ‘Three of the genera and sixteen of 
the species appear to be new to science, and are duly characterized in 
the following pages. Fifty-one of the species, nearly one-half of the 
whole number, also occur in the United States proper, several of them 
ranging as far northward as the State of New Hampshire. Twenty of 
the others have not as yet been reported as occurring outside of Puerto 
Rico, while the remaining forty-six species have also been obtained in 
some other island of the West Indies or in Central or South America. 

Only a very few species of Diptera were described from Puerto Rico 
by the older authors, and it was not until the year 1885 that any con- 
siderable number of species were reported from that island. In that 
year Herr Victor von Roeder, of Hoym, Germany, pubJished a list, with 
descriptions of new forms, of a series of these insects collected by Con- 
sul Krug.! This list numbers 111 species, of which 76 are different 
from those obtained by Mr. Busck; adding these to the 117 species 
obtained by the latter gives a total of 193 species now known to occur 
in Puerto Rico. 

The report in detail is as follows: 


Family CECIDOMYIID 4%. 


DIPLOSIS COCCIDARUM Cockerell. 


Twenty specimens bred from larve associated with Dactylopius citri, 
and nine specimens bred from Lecanium hemisphaericum; also a single

Cayenne, French Guiana, and has been reported from Puerto Rico, 
Cuba, Jamaica, Florida, New York, and Mexico, while the U. S. 
National Museum contains specimens from Georgia, South Carolina, 
Louisiana, California, and Brazil. Macquart has also recorded it from 
Philadelphia, Pennsylvania, Java, and Australia, but it is very doubt- 
ful that this species occurs in either of the two last-named localities. 
Calobata lunulata of van der Wulp! is a synonym, as that author sus- 
pected it might be.

Two specimens, collected at Arroyo and Vieques Island in February. 
This species was originally reported from the District of Columbia, 
but occurs over the greater portion of this country, extending as far 
westward as Colorado. 


LEUCOPIS BELLA Loew. 


Three specimens, bred February 2, from larve preying upon Dactyl- 
opius citrt on Culebra Island. Originally described from Cuba, but 
having a wide distribution, extending from Nova Scotia to California 
and Mexico. . 


Family BORBORID. 


LIMOSINA FONTINALIS Fallen. 


Nineteen specimens, from Bayamon, Utuado, and Mayaguez in Jan- 
uary, and Arroyo and Fajardo in February. A European species, which 
also occurs in the District of Columbia and has been reported from 
Florida by Mr. C. W. Johnson. 


LIMOSINA VENALICIUS Osten Sacken. 


Two specimens, collected at Utuado in January. This species was 
originally described from Cuba, but also occurs at Biscayne Bay, Flor- 
ida, and has been reported from St. Vincent, West Indies, Brazil, and 
Africa. Osten Sacken referred it to the genus Borborus, in which 
genus it is retained by Williston, but it is a typical Limosina, as is also 
the Borborus illotus of Williston. 


LIMOSINA LUGUBRIS Williston. 


Two specimens, taken at Aguadilla and Utuado in January. This 
species was originally reported from St. Vincent, West Indies. 


LIMOSINA PERPARVA Williston. 


Three specimens, collected at Mayaguez and Utuado in January and 
Culebra Island in February. This species was also originally reported 
from St. Vincent. 


Family HIPPOBOSCID. 
ORNITHOMYIA ERYTHROCEPHALA Leach. 


Hight specimens, captured on a sparrow hawk at Adjunctos in Jan- 
uary; also a Single specimen, collected at Culebra Island in February. 
This species was originally described from Brazil, but occurs over a 
large portion of the Western Continent, having been reported by Osten 
Sacken as occurring as far northward as Quebec, Canada.

THE DECAPOD CRUSTACEANS OF WEST AFRICA. 


By Mary J. RATHBUN, 


Second Assistant Curator, Division of Marine Invertebrates. 


This paper was prepared.at the request of Prof. O. F. Cook, for the 
help of collectors and students on the west coast of Africa, and it was 
his intention to publish it as an appendix to his report of work done 
for the New York State Colonization Society. The preparation of that 
report having been unavoidably delayed, it was thought best to publish 
this portion while it is complete. The region covered extends on the 
continent from Senegal to Portuguese West Africa, inclusive, or from 
the River Senegal at about 16° north latitude to the River Kunene at 
17° south latitude. It includes the fresh waters tributary to this coast 
and the islands in the Gulf of Guinea, namely, Princes Island, St. 
Thomas, and Rolas. 

A comparison of the ranges of the species found in this area empha- 
sizes the relation of the fauna to those of America and Europe rather 
-than to the fauna of South and East Africa. Of the 152 species enumer- 
ated, 40 occur also in some of the islands west and northwest of Africa— 
the Azores, Madeiras, Canaries, Cape Verde Islands, Ascension Island, 
or St. Helena—24 species have been recorded from the Atlantic coast 
of America, 25 from Europe or the Mediterranean, 8 are South African, 
5 East African, 6 extend to the west coast of America, while 15 occur 
in the oriental region. The widespread species, Planes minutus, 
Grapsus grapsus, and Pachygrapsus transversus are excluded from the 
foregoing count. 

More than half the species of the list are known to the writer only 
from descriptions. Professor Cook and his colleagues have extended 
the range of several species, and have added one, Clibanarius cooki, to 
those hitherto known 

The classification used in this paper is chiefly, but not wholly, that 
of Claus in the Grundziige der Zoologie. The key to families is made 
up partly from definitions in that work, and largely from those in 
Stebbing’s History of Crustacea.

The perlatus form of this species differs from typical tangert only in 
the great reduction of the larger cheliped of the male and its compara- 
tive smoothness, there being no tubercular ridges on the inner side of 
the palm. The single male of perlatus in the U.S. National Museum

(* Neptunus diacanthus”) from Ogowé, West Africa, and Bahia, Brazil. 
It is impossible to tell without examination of specimens whether these 
so-called “ N. diacanthus” are synonymous with C. bocourti or with other 
species of Callinectes. 

Rochebrune says of Neptunus amnicola, which I think may be identi- 
eal with Callinectes bocourti, that it is found only in the fresh waters of 
rivers and is much sought after for food, the meat being exceptionally 
good. The negroes fish for them to eat and to sell to the Europeans.

The generic name Hippa has here a different signification from that 
commonly indicated. Hippa was established by Fabricius in 1787.! 
Five species were assigned to it, one of which should still remain in the 
genus. Of these five species four were removed in 1798 by Fabricius 
himself to other genera, namely, the species symnista, dorsipes, and 
scabra to Albunea, and the species variolosa to Symethis=Zanclifer 
Henderson, 1888. The single original species, adactyla, left by Fabri- 
cius in the genus Hippa, should be regarded as the type of the genus. 
This species was later made the type of the genus Remipes by Latreille, 
1806, under the name Remipes testudinarius.  Remipes, therefore, 
becomes a synonym of Hippa.

Osorio, Jor. Sci. Lisboa, XI, 1887, p. 222. 

West African islands.—St. Thomas Island (Greeff, Osorio); Rolas 
(Greeff, Osorio). Apparently one species only inhabits these islands, 
and was designated first by Greeff as C. rugosus Milne-Edwards, and 
later as a distinct species, C. rubescens Greeff. Osorio records it under 
both names. 

According to Greeff, these hermits on the island of St. Thomas 
inhabit many different kinds of shells as well as the tests of the sea 
urchins, Hchinometra subangularis and Hipponoe esculenta. They are 
numerous near the beaches, but migrate into the interior, distributing 
and misplacing their marine shells over the whole island, as the growth 
of the inhabitant or the injury to the shell requires its abandonment. 
In such cases they often take refuge in land shells, and returning sea- 
ward scatter these again far from the place where they have arisen and 
properly occur. For example, hermits were found on the beach at the 
mouth of a river in land shells, which naturally do not occur on the 
island at less than 800 meters altitude. 

Osorio found some examples living in the grains of a palm, Hlais 
guineensis.

that P. meticulosus Roux is distinct from P. excavatus (Herbst). It is 
probable that this last should be called P. alatus Fabricius, described 
from Iceland, in 1775; type not extant.

DESCRIPTION OF A NEW BIRD OF THE GENUS 
DENDRORNIS. 


By CHARLES W. Ricumonp, M. D., 
Assistant Curator, Division of Birds. 


The specimen here described was sent to the U. 8. National Museum 
several years ago by Mr. Frank b. Armstrong, who collected it at 
Alta Mira, Mexico. Over twenty skins of Dendrornis flavigaster, 
obtained at the same place, were also received, but none of them shows 
any approach to this apparently new species. It is in general similar 
to D. flavigaster, but differs in having the throat and malar patch 
streaked instead of uniform buff, these markings, as well as those of 
the remainder of the underparts, being for the most part dentate, rather 
than oblong; the under wing coverts are variegated, not uniform. That 
these characters are not those of an immature stage of D. flavigaster is 
shown by several young examples of the latter collected in Mexico by 
Mr. EK. W. Nelson (Biological Survey collection), in which the pattern 
of coloration is similar to that of the adults. 

The new species may be described as 


DENDRORNIS STRIATIGULARIS, new species. 


Type.—Cat. No. 1385157, U.S.N.M.; female adult, Alta Mira, Tamau- 
lipas, Mexico, November 18, 1894; Frank B. Armstrong, collector. 

Top of head and nape dull black, each feather with a prominent 
elongated buff shaft spot; lores buff; sides of head dusky, streaked 
with buff; chin buff; rest of under parts, including under tail-coverts, 
hair-brown, the feathers with long (mainly dentate) buff shaft-mark- 
ings, bordered with dusky black, most numerous on the throat and 
breast, and almost obsolete on the flanks and abdomen. Back bistre, 
broadly streaked with buff, the markings edged with dusky black; 
rump russet; upper tail-coverts burnt umber, the lateral feathers with 
buffy shaft-lines. Tail burnt umber; wings burnt umber, paler on the 
under surface, and terminal portion of inner webs of first five primaries 
dusky. Lesser wing-coverts russet, with narrow paler shaft-lines;

_ middle coverts bistre, with black-bordered buffy shaft-markings; 
greater coverts exteriorly bistre, becoming burnt umber over the terti- 
aries, with more or less concealed buffy shaft-lines, bordered on the — 
outer webs with blackish; primary coverts bistre; edge of wing nar- 
rowly marked with buff and black; under wing-coverts (exteriorly)

DESCRIPTIONS OF THREE NEW BIRDS FROM LOWER 
SIAM. 


By CHARLES W. RICHMOND, M. D., 
Assistant Curator, Division of Birds. 


The birds here described as new were contained in a large collection 
made by Dr. W. L. Abbott in the province of Trong, Lower Siam. The 
collection, which was made during several trips to this locality, embraces 
about 1300 skins, including many not before recorded from the region, 
and some, like Mthopyga temminckii, Geocichla horsfieldi, and G. 
interpres, not previously known from the mainland. A very fine speci- 
men of the rare Thaumatibis gigantea is also contained in the collection, 
which, with Dr. Abbott’s customary liberality, has been sent to the 
U.S. National Museum. 


ZETHOPYGA ANOMALA, new species. 


Type.—Cat. No. 160366, U.S.N.M.; male adult, slopes of the Khaw 
Song, Trong, Lower Siam, at about 2500 feet, March 2, 1897; Dr. W. L. 
Abbott, collector. 

This species is readily distinguished from 1. saturata, its nearest 
ally, and does not require a full description. It differs from 1. saturata 
in smaller size, deeper red on mantle; the dark red wash on sides ot 
breast is more pronounced; the rump lacks the yellow band character- 
istic of other species of the genus, and in this respect it is unique, 
although in 4. saturata the yellow of the rump is considerably 
restricted. In two males of Dr. Abbott’s series of fifteen skins there 
is a slight edging of greenish olive on the rump of the same color as 
the abdomen, very different, however, from the bright, clear yellow of 
saturata and other members of the genus. 

In the female of anomala the yellow rump band is, strange to say, 
very prominent. Unfortunately, I have no females of saturat« for com- 
parison, but those ef anomala are darker and less yellow beiow than 
the figure of the female of satwrata in Shelley’s monograph. 

The adult male measures: Wing, 2 inches; tail, 2.53 inches; culmen. 
0.61 inch; tarsus, 0.57 inch.

CRINIGER SORDIDUS, new species. 


Type.—Cat. No. 169893, U.S.N.M.; male adult, Khow Sai Dow, 
Trong, Lower Siam, 2500 feet, February 14, 1899; Dr. W. L. Abbott, 
collector. 

Upper surface of head bistre, somewhat darker on crest; lores, a 
narrow orbital ring, and a small spot above and posterior to eye, pale 
smoke gray; cheeks and ear-coverts brownish gray, the latter with 
lighter shaft-streaks; throat pure white; breast and abdomen deep 
yellowish buff, washed with smoke gray on the former; under tail- 
coverts brownish buff, the feathers with paler tips; sides of body pale 
olive; sides of neck, back, scupulars, rump, and wing-coverts, olive, 
with a brownish wash on the latter, darkest on the primary coverts. 
Upper tail-coverts, tail, and wings, deep bistre, lighter on the first — 
named; inner webs of wing-feathers blackish brown, with a narrow 
edging of pale wood-brown on under surface; under wing-coverts yel- 
lowish buff. ‘ Length, 94 inches.” 

Dimensions.—Wing, 4.30 inches; tail, 4 inches; tarsus, 0.83 inch; 
culmen, from base, 0.82 inch. A series of nine skins, all of which differ 
from C. gutturalis in their greater dimensions, proportionally longer crest 
and tail; the crest is paler; the back, rump, and sides of chest have 
less greenish olive; there is practically no yellow on the under parts 
and under wing-coverts; the tips of rectrices and borders of inner webs 
of same are not of a pale shade as in C. gutturalis. The nearest rela- 
tive of CO. sordidus is probably C. ruficrissus Sharpe, of Borneo, but of 
this form I have no specimens for comparison. 


TURDINULUS GRANTI, new species. 


Type.—Cat. No. 169874, U.S.N.M.; male adult, Khow Sai Dow, 
Trong, Lower Siam, 1000 feet, February 11, 1899; Dr. W. L. Abbott, 
collector. 

General color above hair brown, becoming mummy-brown on the 
rump and upper tail-coverts, the feathers of the forehead, crown, nape, 
mantle, and back edged with blackish brown; feathers of the mantle 
with whitish shaft streaks. Wings and tail chestnut, the wing-coverts 
like the wing, but lesser coverts with pale shaft streaks; middle and 
greater coverts, secondaries, and tertiaries with small, triangular, apical 
white spots. Sides of head and neck, including lores, a superciliary 
stripe extending to the nape, cheeks, and ear-coverts butfy white, each 
feather tipped with brownish black; a spot before eye and a line behind 
eye extending over the ear-coverts, brownish black. Chin, throat, and 
upper abdomen white, becoming ochraceous buff on the lower abdo- 
men; breast buff, the feathers with almost obsolete dusky edges, the 
feathers on sides of breast with more prominent dusky brown borders. 
Sides of body, thighs, flanks, and under tail-coverts, mummy-brown, 
paler than on the rump; under wing-coverts, edge of wing, and axillars 


No. 1201. NEW BIRDS FROM LOWER SIAM—RICHMOND. 321 


buff, darker on the outer part of the coverts. “Iris dark brown; feet 
fleshy brown; bill dark horny brown above, dull leaden beneath.” 

Dimensions.— Wing, 2.10 inches; tail, 0.96 inch; tarsus, 0.88 inch; 
culmen, 0.57 inch. 

Five specimens from Trong appear to be similar to the Klang exam- 
ple mentioned by Mr. Grant! and it is owing to his careful exposition 
of the genus that I have been able to make a Satisfactory determina- 
tion of the species. i 

This species resembles 7. exsul (of which we have one specimen, from 
Mount Poeh, Borneo), but differs in being smaller, mainly buffy white 
below, a little deeper on the lower abdomen, with the breast buffy white, 
the feathers with indistinct dusky edges; the feathers of sides of breast 
with more prominent dusky borders, but without shaft-streaks; under 
wing-coverts and edge of wing are buff, brownish on the outer edge of 
the former. The sides of body, flanks, thighs, and under tail-coverts 
are lighter than in T. ersul. 

The young bird is somewhat similar to the adult, but is more fulvous 
below; the black edges of feathers on head and back are hardly appar- - 
ent, and the superciliary stripe and spots on wings are fulvous instead 
of white.

ON THE GENERA OF THE CHALCID-FLIES BELONGING TO 
THE SUBFAMILY ENCYRTIN 2. 


By WiLLIAM H. ASHMEAD, 


Assistant Curator, Division of Insects. — 


Among the many thousands of minute Hymenopterous insects exist- 
ing in the world and to which have been given the popular name 
Chalcid flies, there is probably no single family that is of more interest 
or of greater economic importance than the family Encyrtide. 

The species in this family, like the vast majority of other Chalcid-flies, 
live parasitically in the eggs, larvie, or pupe of other insects, and hardly 
_asingle order of Hexapodous insects is wholly free from their attacks; 
but in this family, and more especially in the subfamily Encyrtini, the 
Species are of more than ordinary interest and importance, since so 
many of them are found attacking and destroying the scale- and bark- 
lice (Coccide and Aleyrodide) and the plant-lice (Aphidide and Psyl- 
lide), containing some of the most destructive and troublesome pests 
with which fruit-growers, agriculturists and florists have to contend. 

The subfamilies Eupelmine, Encyrtine, and Signiphorine, the latter 
based upon my genus Signiphora, established in 1880, as I have already 
_ published elsewhere, constitute a distinct family in the subfamily Chal- 
cidoidea, to which the family name Encyrtide should be applied. 

The subfamily Eupelminz was subjected to a generic revision nearly 
three years ago by the present author, and was published in the Pro- 
ceedings of the Washington Entomological Society for 1898. He now 
presents a similar work on the subfamily Eneyrtinze 

The manuscript, as originally written, with the above title, was read 
before the Washington Entomological Society, May 13, 1897. Since 
that time, however, Dr. L. O. Howard ' has characterized a number of 
new genera in the group, and the paper has been withheld from publi- 
cation, in order to incorporate the new genera and to make certain 
necessary changes in nomenclature. ° 

The family Encyrtidz is readily distinguished from all others in the

Chaleidoidea by the large, non-impressed mesopleura, the large triangu- 
lar mesepisternum, which does not extend to the front coxe, and by the large 
saltatorial spur of the middle tibiw, which is most frequently long and 
stout, or dilated at base, and usually armed with a double row of black 
teeth or stiff bristles. No other family possesses this large saltatorial 
middle tibial spur, and only a few species, in one or two of the other 
families, possess the non-impressed mesopleura. 


Family LX VII. ENCYRTID A! 


The three subfamilies mentioned above, into which this family is 
divided, may be separated upon tie following characters: 


Mesonotum not entire, most frequently depressed or concave on disk, rarely convex, 
the parapsidal furrows distinct, or at least more or less present; marginal vein

Mesonotum entire, convex or subconvex, the parapsidal furrows always entirely

Marginal vein rarely very long, often punctiform, and always very much shorter

long; scutellum normal, the axille never closely united to form a transverse

the lateral apical spur lobed .......-----.--2.. Subfamily IIL. SIGNIPHORINA. 


Subfamily Il FHNCY RTIN 4. 


This subfamily, as here defined, is identical with Forster’s family 
Encyrtoide or Mayr’s Encyrtiden, and is based upon Latreille’s genus 
Encyrtus, established in 1809, 

The genus was very imperfectly characterized by Latreille, who 
indicated as types two species, namely, Chrysis ? infidus Rossi (Iliger) 
and Mira macrocera Schellenberg. The latter is now manifestly not 
applicable; since it itself is the type of a well-characterized genus. 
Chrysis infidus Rossi, therefore, becomes the type of Latreille’s genus 
Encyrtus. 

Chrysis infidus Rossi was very imperfectly described and has long 
remained unknown, but I have identified it as the Coccid parasite 
known to us to-day under the name Comys scutellata Swederus. In the 
original description nothing was said of the characteristic tuft of hairs 
on the scutellum, and it has thus been overlooked by writers on these 
insects. 

In 1820, Dalman, a Swede, redescribed the genus Hncyrtus and de- 
scribed many hew species. His diagnosis, however, was necessarily a 
broad one, and in reality represented the family rather than the genus, 


‘For characters of the other families see Classification of the old family Chal- 
cidide by W. H. Ashmead, Proc. Wash. Ent. Soe., IV, 1898-99, pp. 242-249. 


‘No. 1202. GENERA OF THE ENCYRTINE—ASHMEAD. Bae 


and in it he included many species that are now relegated to many of 
our more modern genera. 

From the publication of Dalman’s paper down to the year 1856 several 
new genera were erected by Dahlbom, Nees, Westwood, Haliday, 
Walker, and hKatzeburg, either upon some of the Dalmanian species, or 
upon new discoveries. 

In 1856 a great advance was made in our knowledge of the group 
by Dr. Arnold Forster, in his well known publication Hymenoptero- 
logische Studien, Heft II, in which he for the first time properly defined 
the group as a family under the name Encyrtoidex, brings together the 
known genera in tabular form, and describes no less than twelve new 
genera. 

A year later, or in 1857, Dahlbom established four new genera, namely, 
Ageniaspis, Huscapus, Lonchocerus, and Trimorphocerus. The second is 
identical with Dinocarsis Forster, the third with Mira Schellenberg, 
while the fourth and last seems to have been based upon a male Both- 
riothorax. 

The Russian General Motschulsky, in 1863, erected his genus Cal- 
lipteroma' from Ceylon; while a few years later an Italian, Camillo 
Rondani, described in the group three additional genera, wretchedly 
characterized, namely, Tineophaga, 1868, Tineomyza, 1872, and Selitre- 
chus, 1877. None of them, however, belong here, but all belong to the 
family Eulophide. Tineophaga equals Hulophus Geoffroy; Tineomyza 
is apparently identical with Tetrastichus Haliday; while Selitrechus, as 
I have identified it, is a good genus in the subfamily Entedonine. 

In 1876 the European genera and species of the Encyrtinze were sub- 
jected to a thorough revision, by Dr. Gustav Mayr, of Vienna, Austria, 
in a work entitled Die Europiiischen Encyrtiden, biologisch und sys- 
tematisch bearbeitet. 

In this most valuable contribution Dr, Mayr has shown that several 
of the previously described genera were synonyms, being based prin- 
cipally upon the opposite sex or upon apterous or subapterous forms of 
other genera. Dr. Mayr in his work, however, established 8 new genera, 
gave full descriptions of all the known genera and species, except 
some of Walker’s, besides characterizing 25 species as new to science. 

About the time of the appearance of Dr. Mayr’s excellent work on 
the group, the well-known Swedish entomologist, Dr. C. G. Thomson, 
was also engaged in a systematic study of the Encyrtine, and the result 
of his labors appeared shortly afterwards.’ 

The title-page of this work antedates that of Dr. Mayr’s, and I was 
at first inclined to give Thomson priority for certain genera which 
prove to be synonymous with those of Dr. Mayr’s. _Since my paper 
was read, however, Dr. L. O. Howard has most conclusively shown, 


‘Von Dalla Torre records this in his Catalogus Hymenopterorum under the family 
Braconid. 
? Skandinaviens Hymenoptera, IV, pp. 112-183. 


326 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXII. 


from a letter from Dr. Christopher Aurivillius, of the Stockholm 
Museum, the incorrectness of this title-page, and proves without the 
shadow of a doubt the priority in publication of Dr. Mayr’s work. 

The group was called by Thomson a tribe—Encyrtina—and he divided 
it into three sections, based principally upon mandibular characters, 
besides giving an excellent table for distinguishing the genera. Hight 
new genera and 26 new species were described. Three of these genera 
are, however, Synonyms: Liocarus equals Prionomastix Mayr; Nob- 
rimus equals Homalotylus Mayr; while Trechnites equals Metallon 
Walker. 

Thomson designates as the type of Encyrtus, E. scutellaris Dalman, 
a species evidently synonymous with Hneyrtus (Chrysis) infidus Rossi. 

The work of Thomson is unquestionably of great value, and he has 
drawn attention to several important structural characters not pre- 
viously or subsequently noticed. In my own work I have made use of 
some of these characters, one of which—the shape and dentition of the 
mandibles—although not easily seen, I consider of tribal value. 

In 1888 Christopher Aurivillius discovered and described his genus © 
Arrhenophagus, a remarkable form in the group. 

A year later, 1889, De Stefani, an Italian, established his genus 
Hoplopsis, a genus still unknowa to me in nature, but which, judging 
from the description, does not belong to this subfamily, but to the sub- 
family Eupelmine, “‘ Thorax foveolatus” being a character found only 
in the Eupelminze. © 

In the United States until within comparatively recent years very 
little original work was done in the family. 

The first American who described a species in the group was Thomas 
Say, whose Serlion terminalis, described in 1828 and placed by Cresson 
in the genus NScelio, in the family Proctotrypide, is an encyrtine 
belonging to Mayr’s genus Homalotylus. 

It has been since redescribed twice: Once by Dr. Shimer as Hutelus 
scymne, and again by Dr. Howard as Homalotylus obscurus. 

Since Say’s time, besides myself, the only one in this country who 
has given special attention to these inseets is Dr. L. O. Howard, whose 
valuable contributions toward elucidating the habits, genera, and spe- 
cies of this difficult group, found in America, are known to all working 
entomologists. He has characterized many new genera and many new 
species—many beautifully figared—and it is through his kindness and 
liberality in placing at my disposal all his material in the group that I 
am able to incorporate all of these genera in my tables. 

I desire here also to express my thanks and obligations to the well- 
known hymenopterologist, Dr. Gustay Mayr, of Vienna, Austria, the 
leading HKuropean authority on the group, for sending me during our 
correspondence, extending over an interval of nearly twenty years, 
Specimens of most of the European genera. 

With these preliminary remarks I shall now proceed tbh the classi- 
fication of the eel

The species falling in this tribe are, as a rule, more elongate and 
narrower, the marginal vein proportionately longer, the stigmal vein 
shorter, while the mandibles are longer, narrower, and always bidentate 
atapex. This last character, together with the prominent hypopygium, 
in the female, may always be depended upon to distinguish a species 
falling in this group. 

The genera may be recognized by the use of the following table:

- The species belonging in this tribe are broad and robust, with broad, 

stout mandibles which are broadly truncate at apex and edentate or very 

nearly; the labrum is conspicuous; the antenne similar in both sexes, 

the marginal vein in the front wings short, the stigmal and postmar- 

ginal veins usually long; in the hind wings the marginal cell is long, 

broad, and distinet, while the hind tibiz have two apical spurs. 
Only three genera are known, separated as follows:

To this tribe belong the vast majority of the known Eneyrtine. Itis 
distinguished from the other tribes principally by the mandibles, which 
are somewhat differently shaped, and always tridentate at apex. In 
most of the genera these have three small equal, or very nearly equal, 
teeth, while in others the outer tooth is the longest and most acute. 
One or two genera, however, have the two outer teeth longer than the 
inner. The marginal cell in the hind wings is usually long and narrow, 
nearly obsolete, but never very broad, as in the Encyrtini; while the 
hind tibie have only one apical spur. 

It may be well here to call attention to two tribes founded provision- 
ally, in 1892 and 1895, by Dr. L. O. Howard, since all of one and part 
of the other belong here, namely, the Tetracnemini,' and the Bothrio- 
thoracini,? which Dr. von Dalla Torre, in the fifth volume of his Cata- 
logus, has elevated to subfamily rank. 

The first is an unnatural assemblage of genera, as Dr. Howard has 
already pointed out, based upon the fact that certain genera have been 
discovered having ramoseantenne in the males, which in itself, although 
interesting, is of no tribal significance, since there is scarcely a family 
in the Order Hymenoptera, from the most specialized to the more gen- 
eralized, that does not possess one or more genera with this character- 
istic feature. 

The second, or the tribe Bothriothoracini, too, seems to have scarcely 
any more reason for its existence, being based principally upon the 
thimble-like punctuation possessed by certain genera, all the other 
characters mentioned by Dr. Howard, in his diagnosis of the tribe, 
being common to many other genera. The thimble-like punctuation of 
certain genera, as well as other styles of punctuation, is a valuable 
diagnostic character, but of no other value, since I find all intermediate 
grades, from the strong, thimble-like punctuation possessed by Both- 
riothorax, of varying shades and degrees, down to a perfectly smooth 
impunctate surface. I consider, therefore, that both tribes are unnat- 
ural and not tenable. 

The genera of this tribe are exceedingly numerous, about 59 having 
_been recognized. It is believed, however, that all can be easily dis- 
tinguished by the use of the following table.

This tribe is proposed for two genera differing decidedly from the 
other tribes in mandibular characters, as well as in general habitus. 
The mandibles are acutely pointed or conical, and edentate: the tarsi 
4 or 5 jointed; while the marginal vein is wanting or punctiform, the 
postmarginal vein wanting, the stigmal vein sometimes present.

2. TETRALOPHIDEA Ashmead, new genus. 
(Type, Tetralophidea bakeri Ashmead.) 


This genus comes nearest to Calocerinus Howard, but the head is not 
quite so large nor so broad proportionately; the lateral ocelli are more 
distant from the eye margin, being about three times as far from the 
eye margin as their diameter; the pronotum is shorter; the mesonotum 
and scutellum are less convex; the wings are clear hyaline, not fuscous 
with white bands, as in Calocerinus; while the abdomen is proportion- 
ately longer. 

The genus is readily separated from Calocerinus, the only one with 


which it shows any affinity, by the hyaline wings and the position of the © 


ocelli. 
1. TETRALOPHIDEA BAKERI Ashmead, new species. 


Male.—Length, 1.5 to nearly 2 mm. Head and thorax aeneous black, 
the mesopleura blue; mandibles dark rufous or ferruginous, bidentate; 
legs aeneous with all the tarsi brown-black or dark fuscous. Head 
and thorax above with a distinct metallic luster, and microscopically 
reticulate or shagreened, the face with some scattered punctures. 
Antenne 11-jointed, inserted below the middle of the face, the flagellum 
with four long pilose branches, a branch on joints 1-4; pedicel obconieal, 
searcely longer than thick at apex, funicle6-jointed, the first joint annular, 


the fourth elongate, more than twice longer than the three preceding, the

fifth and sixth also elongate, but shorter. than the fourth; club fusi- 
form, indistinctly 3-jointed. Mesonotum subdepressed in front of the 
scutellum; axillz not quite meeting at base of scutellum; metathorax 
short, with the hind angles smooth, bare. Wings hyaline, the venation 
mostly dark-brown or piceous, the submarginal vein, except at apex, 
pale yellowish; marginal vein about thrice as long as the stigmal, the 
postmarginal short, not longer than the stigmal, the latter being short, 
subpetiolate and ending in a knob. Legs aeneous black, the hind 
coxe metallic green, the tarsi brown-black or fuscous, the anterior and 
middle tarsi basally and the middle tibial spur, yellowish.

3. MEROMYZOBIA Ashmead, new genus. 
(Type, Hricydnus maculipennis Ashmead. ) 


Stature and general appearance of Hricydnus Walker, but readily 
distinguished from it and allied genera by its antennal characters, the 
funicle being only 4-jointed, with two small ring-joints. It is the only 
genus in the tribe Hctromini with two ring-joints, aud includes wingless 
or subapterous forms, as well as those with wings fully developed. 

Head transverse, viewed from in front rounded, the frons subconvex, 
finely shagreened or coriaceous, with a few minute punctures scattered 
over the surface. Mandibles bidentate. Antenne 11-jointed—scape, 
pedicel, two ring-joints, a 4-jointed funicle, and a 3-jointed club. Prono- 
tum conical, the hind margin obtusely triangularly emarginate; meso- 
notum smooth, a little wider than long; scutellum about two-thirds the 
length of the mesonotum, with the axillxe touching each other at their 
inner basal angles; metathorax short, about one-third the length of the 
seutellum, smooth. Winged form with the wings hyaline, but banded, 
or at least maculate with fuscous; the marginal vein is somewhat long, 
linear; the stigmal is always shorter than the marginal and issues 
obliquely at an angle of less than 30 degrees; the postmarginal vein is 
a little longer than the stigmal, but shorter than the marginal. Abdo- 
men conic-ovate, and usually a little longer than the thorax. 

The species in this genus, whose parasitism is known, destroy Dip- 
terous Jarvee belonging to the genus Meromyza. The following are the 
Species of our fauna:

hind tibiz, tibial spurs and tarsi, except terminal joints, yellowish white; 
eyes purplish brown; flagellum brown; wings hyaline, the marginal and 
stigmal veins brown. Abdomen short oval. 

Antenne 9-jointed (scape, pedicel, 4 funicle joints and an indistinetly 
5-jointed club); the flagellum is subcompressed, the joints of the funicle 
about thrice as long as wide or the fourth is somewhat shorter; the 
club is longer than the slender scape, 3-jointed, but the sutures sepa- 
rating the joints are made out with difficulty; the pedicel is very small, 
hardly longer than thick.

lum, the metanotum, and the middle tibix, except distal ends, obfur- 
cated; hind femora, their tibiz, except basal two-thirds, which is 
white, and their tarsi, fuscous. Abdomen black, with the basal seg- 
ment yellowish. Wings, hyaline, with a large discoidal fuscous cloud 
beneath the marginal and stigmal veins.

5. TINEOPHOCTONUS Ashmead, new genus. 


(Type, Phanodiscus armatus Ashmead.) 


This genus also resembles Hricydnus Walker, but the abdomen is 
longer, more compressed, and terminates in a long, prominent oviposi- 
tor, while the venation of the front wings is different, the marginal vein 
being long, linear, while the stigmal and nasinremen rel veins are very 
short. 

Two species belong here, Phwenodiscus armatus Ashmead, and Lepto- 
mastix tineevora Ashmead, the latter being based upon a specimen 
that had the ovipositor broken off.

the axille separated, not meeting at base of the scutellum, while the 
abdomen is strongly compressed, a little longer than the tend and tho- 
rax united, with a prominent, exserted ovipositor and a large, promi- 
nent lanceolate hypopygium, which projects far beyond the tip of the 
abdomen. Wings much abbreviated, hardly developed. 


1. HENICOPYGUS SUBAPTERUS Ashmead, new species. 


Female.—Length, 2-2.5 mm.; to tip of ovipositor, about 3 mm. 
Ground color of head, thorax, and legs is ferruginous, but the head 
above the antenne, including the vertex, and the thorax above are 
bronzed or metallic brown; the mesopleura superiorly show a decided 
violaceous tinge, while the abdomen is black above, blue-black beneath; 
the ovipositor black at apex, whitish on basal two-thirds. 

The small joints, upon which the antenne are inserted, are unusually 
long, well developed, black; scape brownish-yellow, the pedicel and 
flagellum black. Wings very short, scarcely developed, and not extend- 
ing to the apex of the first abdominal segment, brown, but with a white

18. TETRALOPHIELLUS Ashmead, new genus. 
(Type, Tetralophiellus brevicollis. ) 

This genus is allied to Tetracladia Howard, but may be easily sepa- 
rated by the longer marginal vein, which is about three times as long 
as the stigmal, by the axille, which meet at their inner basal angles, 
and by the much shorter pronotum, which is scarcely visible from above. 


1. TETRALOPHIELLUS BREVICOLLIS Ashmead, new species. 


Male.—Length, 1.2 mm. Bronzed green, the mesopleura bluish or 
purplish; legs brown-black, all tibise with a white annulus at base, 
the tips of anterior and middle tibiz and all tarsi, except the last joint, 
whitish. The antennie are black, with funicle joints 1-4 each, fur- 
nished with a long, hairy branch. Head shagreened, the mesonotum 
scaly-punctate, the scutellim smoother but with delicate reticulate 
lines. Wings hyaline, the veins brown. 

Type.—Cat. No. 4731, U.S.N.M. (Ashmead collection.) 

Habitat.—Florida: Jacksonville.

20. TETRACNEMOPSIS Ashmead, new genus. 


(Type, Tetracnemus westwoodii Cockerell. ) 


Differs from Tetracnemus Westwood in having the marginal vein fully 
twice as long as thick, about half the length of the stigmal, the post- 
marginal vein developed, the pronotum transverse linear, the scutellum 
longer than the mesonotum, while the axille meet just in front of the 
seutellum. 

The female, which was unknown to Cockerell, has the head, seen from 
in front, longer than wide, the eyes large, the face and forehead nar- 
rowed; the antenn are 11-jointed, inserted close to the clypeus with a 
distinet carina between, the scape obclavate, the flagellum clavate, the 
club enlarged, ovate, thrice as thick as the funicle; while the hypopyg- 
ium is prominent, plowshare shaped, and projects considerably beyond 
the tip of abdomen. ; 

The pedicel and first four joints of funicle are white, the scape, last 
two joints of funicle and the club, dark brown.

22. HABROLEPOPTERYX Ashmead, new genus. 
(Type, Psilophrys pulchripennis Ashmead. ) 


The colorational pattern of the front wings in this genus is similar 
to that in Habrolepis Forster, but otherwise there is not a particle of 
affinity between the two genera, since structurally they are widely 
separated. 

The species was originally described in the genus Psilophrys on 
account of the long head. It has, however, no relation whatever with 

.that genus, not even belonging to the same tribe. 

The rather full structural characters given in my table render a fuller 
description here unnecessary, since no one could go astray in placing 

so characteristic a genus.

2. AANASIUS CHAPAD Ashmead, new species. 


-Female.—Length, 1 mm. Robust, short and broad, very little longer 
than wide. Head blue, thorax above blue-black, beneath ceneous black; 
abdomen metallic eneous; scape within and at tip, and the funicle pale 
brown, rest of scape and the club brown-black; legs dark brown, the 
tarsi light brown or yellowish; wings subfuscous. 

The head is covered with a close, thimble-like punctuation, ciear to 
the scrobes, which are short; the eyes are large, long-oval, and pubes- 
cent; the scape has the characteristic leaf-like expansion beneath; the 
funicle is short, the joints, except possibly the first, which is small and 
moniliform, are wider than long and increase in width to the club, the 
latter being very large and as long as the funicle and very much 
thicker. The thorax is similar to that in A. hyettus Walker, except 
that mesonotum has the thimble-like punctuation similar to that of the 
head, only less distinctly impressed; the scutellum is large, about twice 
as long as the mesonotum, with the punctuation almost obsolete.

44. HEMANASIUS Ashmead, new genus. 
(Type, Hemenasius confusus Ashmead. ) 


Aspect of Mnasius Walker and Huryrhopalus Howard, but quite dis- 
tinct from both in sculpture and in following characters: I’rom Mnasius 
it differs in punctuation, in the much longer scape and flagellum, the 
former being only slightly dilated, the longer mesonotum and in vena- 
tion; from Huryrhopalus in the broader vertex, antennal characters, 
and in the quite different venation, brought out in my table. 


1. HEMANASIUS CONFUSUS Ashmead, new species. 


Female.-—Length, i mm. Robust, black, the head anteriorly from the 
front ocellus blue; ‘flagellum brown-black, the scape at base and apex 
yellowish; funicle joints 4 and 6 whitish; tips of tibia and tarsi, 
except last joint, honey-yellow; wings hyaline, dusky or fuliginous at 
base only, the marginal vein punctiform, the postmarginal vein devel- 
oped but slender, about two-thirds the length of the sigmal; all veins 
brown. The head on vertex has some small scattered punctures but 
anteriorly it is perfectly smooth and polished; the thorax is almost 
smooth, but with a strong lens one can detect some delicate transverse 
strie and a few microscopic punctures; abdomen short, broadly oval, 
smooth and shining.

Habitat.—Florida: Biscayne Bay. 


46. HEMENCYRTUS Ashmead, new genus. 
(Type, Hemencyrtus herbertiit Ashmead.) 


Stature and general appearance of Hncyrtus cecidomyie Howard, but 
quite different in sculpture and in venational and antennal characteris 
tics. The head is scarcely as wide as the thorax between the wings, 
lenticular, shagreened, but with sparse, distinet, umbilicate punctures 
on the forehead. The antenne are 11-jointed, filiform or nearly, and 
clothed with short, sparse hairs, the joints of the funicle all being alittle 
longer than wide; the club is rather short, scarcely as long as the 
pedicel and first joint of fanicle united, the pedicel being obeonical and 
hardly twice as long as thick. 


No. 1202. GENERA OF THE ENCYRTIND—ASHMEAD.- 375 


The pronotum is distinct, not short, about two-thirds the length of 
the mesonotum, the latter being twice as wide as long and somewhat 
shorter than the sentellum. The front wings have a short marginal 
vein which is only about twice as long as thick, or a little longer; the 
stigmal vein is nearly twice as long as the marginal, while the post- 
marginal vein is very much longer than the stigmal. Abdomen in 
female conically pointed, somewhat longer than the head and thorax 
united, with the ovipositor exserted, the sheaths being very broad. 


1. HEMENCYRTUS HERBERTII Ashmead, new species. 


Female.—Length, 2.8mm. Dark blue; collar, scutellum toward apex, 
metapleura, and abdomen aeneous black; antenne, except three or 
four apical joints, and the legs, except the cox, brownish-yellow. Head 
with sparse but distinct thimble-like punctures on forehead and along 
the inner orbits; the scrobes form a distinct semicircular depression. 
The mesonotum is smooth apparently, but with a strong lens one can 
detect a vaguely defined or indistinctly impressed thimble-like punctua- 
tion. Wings subhyaline; tegul piceous, the subcostal vein yellowish, 
while the marginal, stigmal, and postmarginal veins are brown. Abdo- 
men a little longer than the head and thorax united, depressed or concave 
above, carinate beneath; the ovipositor exserted to nearly one-third its 
length, with very broad, compressed sheaths. 

Habitat.—Brazil: Chapada. (Herbert H. Smith collection.) 


47. COCCOPHOCTONUS Ashmead, new genus. 
(Type, Coccophoctonus dactylopti Ashmead.) 


Form very broad and. robust, resembling somewhat the genus Phe- 
nodiscus Forster. The head is lenticular, wider than the thorax, with 
very large oblong-oval eyes, the frons in consequence being rather 
narrow but still with the thimble-like punctuation. The antenne are 
very short, the flagellum being scarcely longer than the slender scape, 
the club very large and distinctly longer than the short funicle, the 
joints of the latter being very small, transverse or annular. The pro- 
notum is short; the mesonotum fully twice as wide as long, shorter than 
the scutellum and smooth or very indistinctly punctate. The wings, 
unlike those in Phenodiscus, are hyaline, the marginal vein being 
scarcely three times as long as thick, the stigmal vein longer than the 
marginal, while the postmarginal vein is fully as long as the marginal 
and stigmal veins united. The abdomen in outline is triangular, broadly 
sessile, depressed, and much shorter than the thorax. 

The male resembles the female, but is much smaller, narrower, less 
robust, with the head smaller and not broader than the thorax; other- 
wise in antennal and venational characters it agrees with the female. 


r. COCCOPHOCTONUS DACTYLOPII Ashmead, new species. 


Female.—Length, 1.4mm. Robust. blue-black, the abdomen aeneous; 
Scape pale yellowish; all tibive and tarsi, apical third of middle tibiz, 


376 PROCEEDINGS OF THE NATIONAL MUSEUM. Vou. XXM. 


and the apical half, or a little more, of the hind femora, honey-yellow. 
The middle tibize are sometimes dusky toward base. Frons with a 
rather close thimble-like punctuation; mesonotum nearly smooth, but 
with a sparsely, vaguely defined punctuation; scutellum shagreened. 

Male.—Length, 0.9 mm. Differs from female in being much smaller, 
narrower, and Jess robust; the legs are brown-black, with tips of femora 
and the tibiz and tarsi honey-yellow, while the anterior and middle 
tibize are more or less dusky or fuscous basally.

49. RHYTIDOTHORAX Ashmead, new genus. 
(Type, Rhytidothorax marlatti Ashmead.) 

Allie l to Phenodiscus Forster, but much less robust and with the 
following structural differences: The wings are hyaline, the marginal 
vein being longer than the stigmal, while the costal cell in the hind 
wings is long and narrow. The head is scarcely as wide as the thorax; 
eyes pubescent; antenne rather long; the flagellum subclavate, not 
ringed with white; the funicle joints 2-6 transverse, the pedicel obconi- 
eal, three times as long as thick, or longer than the first joint of the 
funicle. The head has the usual thimble-like punctuation, but the 
mesonotum is shagreened or rugulose, especially anteriorly, while the 
scutellum is more distinctly, although somewhat finely, shagreened.

87. OOENCYRTUS Ashmead, new genus. 
(Type, Hneyrtus clisiocampe Ashmead. ) 
This genus is proposed for certain species described under the genus 


Encyrtus (sens. lat.), bred from the eggs of different insects, since they 
can be no longer retained in that geuus as now restricted. 


382 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXIL 


It is at once distinguished by the very minute, short, usually puncti- 
form marginal vein, which is not or scarcely longer than thick, and the 
non-developed or extremely short post marginal vein, similar to Copido- 
soma Katzeburg. 

Its other characters, however, are quite different from that genus, 
the face being short, the antennal characters and punctuation being 
characteristic. It comes closest to Prionomastix Mayr, but its cephalic 
and antennal peculiarities, made use of in my table, readily separate it 
from this and allied genera. 

Judging from their hosts, the European species Encyrtus notodonte, 
E. tardus Ratzeburg (= HL. ovulorum Forscolomb) and EH. embryophagus 
Hartig, probably belong here. 

Our species are are as follows:

58. PSYLLAZPHAGUS Ashmead, new genus. 
(Type, Lneyrtus pachypsylle Howard.) 


This genus comes closest to Ooencyrtus, but is at once distinguished 
by the broader vertex, the position of the lateral ocelli, and the distinct 
but short postmarginal vein, as pointed out in my table. 

The species belonging to it seem to confine their attacks to nymphs 
in the Homopterous family Psyllide. 

The following are the known species in North America:

59. COCCIDENCYRTUS Ashmead, new genus. 
(Type, Encyrtus ensifer Howard.) 


Comes nearest to Ooencyrtus and Psyllephagus, but easily separated 
by the longer or distinct postmarginal vein, and by the differences in 
the antennz, the club in female being much longer than in those two 
genera, the pedicel shorter, and the funicle joints smaller, submonili- 
form. In the male the flagellum is much longer, ending in a distinct 
club, the funicle joints about twice as long as thick, subnodose above 
and with half whorls of long hairs. The head is transverse, as wide 
as the thorax, with a vertex of moderate width, not narrow, the ocelli 
triangularly arranged, the lateral ocelli not lying close to the eye mar- 
gin—at least their width, or a little more, from it. Abdomen short, 
triangular, as viewed from above, with the ovipositor subexserted, the 
sheath projecting somewhat beyond the top of abdomen.

This species probably represents a variety of the Kuropean MM. tes- 
sellatus Dalman. It agrees with it in stature and in wing markings, 
except that the triangular white marginal spots are connected so as to 
form an additional band, while the head and thorax at sides, too, are 
quite differently colored. The head, the pronotum, except above, the 
sides of the thorax, and the legs, are brownish-yellow, while the 
mesonotum is metallic blue.

(Type, Aphycus niger Ashmead.) 


tesembles both Aphycus and Blastothrix. The front wings have a 
hairless oblique line, extending from base of stigmal vein to the hind 
margin as in Aphycus, but the venation is quite different: The marginal 
vein is distinct, not punctiform, although shorter than the stigmal vein; 
the postmarginal vein is long, well developed, and a little longer than 
the marginal and stigmal veins united. The antennz are subclavate, 
the scape only slightly thickened towards tip, and not at all dilated 
beneath, asin Aphycus and Blastothrix, while all the joints of the funicle, 
in the male, are wider than long, neither subdentate, nor with half 
whorls of hairs, as in blastothrix. The body, at the most, is clothed 
with a fine, sparse pubescence; the head and thorax are subopaque, 
finely coriaceous; the frons broad; the ocelli arranged in a triangle, 
the lateral far from the eye margin; scrobes distinct; scutellum a little 
longer than the mesonotum, with a delicate grooved line at the basal 
half; metathorax very short, abrupt; abdomen small, oval, depressed, 
scarcely two-thirds the length of the thorax.

67. PSEUDENCYRTUS Ashmead, new genus. 
(Type, Encyrtus cecidomyie Howard.) 


To this genus belong several species placed by writers in Hneyrtus 
(sens. lat.). It is founded upon Hneyrtus cecidomyiw Howard, and to it 
belongs also the European species Encyrtus clavellatus Dalman. 

The species are strongly metallic and live parasitically in the Dip- 
terous larvee belonging to the family Cecidomyide. 

The thorax is smooth, impunctate, or at most with a delicate, micro- 
scopically reticulate punctuation; the stigmal vein is rather long, 
oblique, and usually a little longer than the marginal and postmarginal 
veins united; the axilla do not quite meet at their inner basal angles; 
the antenne are moderately long, subclavate, the 3-jointed club not 
much enlarged, only about half the length of the funicle or less, and 
not much thicker than the terminal joint of the funicle; the funicle 
6-jointed, subeylindrical, the joints all longer than wide, never monili- 
form, while the abdomen in female, in outline, is conic-ovate, depressed 
above and usually somewhat longer than the head and thorax united, 
‘or at least as long, the ovipositor always slightly exserted.

68. EPIENCYRTUS Ashmead, new genus. 
(Type, Lncyrtus thyreodontis Ashmead.) 


This genus represents part of a group to which European writers 
have applied the generic term Hncyrtus Dalman. The types of the 
genus are Lncyrtus thyreodontis Ashmead and Ene. melanacis Daiman. 


No. 1202. GENERA OF THE ENCYRTINE—ASHMEAD. 397 


It comprises a group which appears to be hyperparasitic on Iehneumon 
flies belonging to the subfamily Ophionine; at least such appears to 
be the case with two of the North American species, and I should not 
be surprised to find all the species, failing in the genus, hyperparasitic. 

The stigmal vein is never longer than the marginal and postmarginal 
united, most frequently distinctly shorter; the axille usually meet at 
their inner basal angle; the antenne are rather short, the club much 
enlarged, as long, longer, or nearly as long as the funicle, and from two 
to three or more times wider than the last joint of the funicle; the 
funicle is 6-jointed, short, the joints transverse wider than long, or at 
least the 3 or 4 terminal joints, or the first 3 or 4 joints are moniliform, 
while the abdomen is ovate or pointed ovate, but not longer than the 
head and thorax united, usually somewhat shorter, the ovipositor not 
or only slightly extending beyond the tip of the abdomen.

antennee brought out in ny table.

7O. APHIDENCYRTUS Ashmead, new genus. 
(Type, Eneyrtus aphidiphagus Ashmead. ) 


The characters used in my table of genera readily separate this genus — 
from Pseudencyrtus and Epiencyrtus, the only genera, except possibly 
Ooencyrtus, with which it could be confused. Its resemblance to the 
last-mentioned genus, lies only in venational characteristics, since the 
marginal vein is also short, nearly punctiform; the other characters 
mentioned may, however, be depended upon to distinguish it. 

All of the species falling in this genus, known to me, are parasitic on 
Homoypterous insects belonging to the family Aphidide. It is also prob-

the very short antennz which have the club enormously enlarged, longer 
-, than the funicle and many times thicker, the joints of the funicle being 
transverse; and by the clear hyaline wings.

short, the flagellum clavate, the club enlarged, but not enormously so,

as in Zaomma, only about twice as broad as the funicle, but as long or 
nearly; funicle joints transverse, the first two or three smaller than 
the others, submoniliform; pedicel rather large; scape short, subclav- 
ate or slightly thickened toward apex. Wings hyaline, but with the 
venation quite different from that of Zaomma, the postmarginal and 
stigmal veins being much shorter than in that genus. 

The male, or what I take to be the male, has the flagellum filiform, 
tapering off at tip, with the joints a little longer than thick, and 
clothed with a very short, fine pubescence.

(Type?) 

Ratzeburg, in his original description of this genus, as has been 
shown by Dr. Howard, confused with it a number of species belonging 
to Aphelimus or allied genera; but, nevertheless, he must have had before 
him at least one genuine Encyrtine, as his figure, both of venation and 
antenna, clearly shows; and I here restore the name for a species 
agreeing in all particulars with his brief diagnosis and his figure. No 
Aphelinine has a wing-venation as figured by Ratzeburg. .

A HUNDRED NEW MOTHS OF FHE FAMILY NOCTUIDA. 


By Joun B. SMITH, Se. D., 


Rutgers College, New Brunswick, New Jersey. 


Among the specimens sent me by correspondents for determination 
from time to time there is always a little residue that can not be cer- 
tainly named. The material is for some reason or other not sufficient, 
or not satisfactory enough to make it safe to say that a new species is 
at hand, and the specimens are placed with their nearest allies, 
awaiting mates. The mere description of species is not to me an 
agreeable task, and so, gradually, specimens have accumulated until 
it seems necessary to put them into their proper places to facilitate 
future recognition. In the descriptions presented herewith the source 
of the specimens is acknowledged in almost every instance. Where 
it is not done, it is because accurate data no longer exist. With few 
exceptions, the types of the species are now or will be deposited in the 
U.S. National Museum. The exceptions are principally of specimens 
belonging to other institutions, or where I could not dispose of the 
specimens according to my own inclinations. ‘There are a few notes on 
other species; but the paper, as a whole, is intended to be descriptive.

1. ARSILONCHE COLORADA, new species. 


Ground color a rather pale reddish luteous, somewhat sparsely pow- 
dered with black scales. On the thorax these scales tend to form.a 
submarginal line. On the primaries they form a very obscure little dot 
at the lower angle of the cell and vague streaks in the interspaces, the 
veins being narrowly white marked. The indication is that the streaks 
in the interspaces of the median and submedian series may become 
well marked, but in the two examples before me there are no contrasts. 
Secondaries more whitish, a vague marginal shading, else immaculate. 
Beneath somewhat paler, disk of primaries somewhat smoky, else 
immaculate. 

Expanse, 31 to 33 mm. = 1.24 to 1.32 inches. 

Habitat.—Glenwood Springs, Colorado; September, Dr. Barnes. 

Two females, who have for some years been awaiting a mate. The 
Species is now described because it is not easy to mistake it, and it 
differs obviously from our eastern form in the smaller size and more 
dull, reddish luteous coloring. 

Incidentally, it may be said that it is probable that Mr. Grote’s name 


/ NO.1208. NEW NOCTUID MOTHS—SMITH. 415 


_ henrict may have to be reinstated for the eastern form usually named 
 albovenosa. It seems that there is a small, though constant, difference 
in the male sexual parts, which is not accompanied by any noticeable 
superficial differences and seems not to be accompanied by any larval 
differences obvious to Dr. Dyar. 


2. CHYTONIX SEMIFASCIA, new species. 


Ground color a somewhat smoky brown, variously powdered. Head 
without obvious markings, collar with a black tip, disk of the thorax 
pure white, in strong contrast with the rest of the markings. Edge of 
the patagia blackish; the scales of the posterior tuft brown tipped. 
Primaries with the upper half of the wings smoky brown, the lower 
half blackish brown, the shades merging gradually. The markings are 
all obscure and are traceable with difficulty. The basal line is marked 
on the costa only and never distinctly. The transverse anterior line is 
geminate, but the outer line only is obvious. In course it is usually 
oblique, with the usual outcurve below the median vein. Transverse 
posterior line geminate, both parts of it almost equally indistinct, the 
inner perhaps a little the better marked. The defining lines are very 
even, but the line as a whole is almost rectangularly bent over the cell 
and then incurved below. The subterminal line is scarcely marked 
above the middle except by a blackish dash near the apex. Below the 
middle it is traceable as a gray or whitish shading through the dusky 
part of the wing. There is a smoky terminal line, beyond which there 
is a pale line at the base of the fringes, which are interlined with black- 
ish and cut with brown on the veins. The ordinary spots are vaguely 
indicated, outlined by very slightly darker brown shadings. There is 
a distinct black basal dash, which reaches the transverse anterior line, 
and beyond it is the small, loop-like claviform, which is defined in a 
pure white patch which fills the median space between the median 
lines and extends upward to the median vein. Through this white 
patch some specimens show the remnant of a median shade. Beyond 
the transverse posterior line a blackish shade forms the continuation 
of the basal line and reaches the subterminal line. Above this there 
is a little black sagittate mark. Toward the apex there is a brown 

shading which is broad on the margin and narrows toward the subter- ~ 
minal line. Secondaries yellowish white, a little silky in appearance, 
with a blackish line at the base of the fringes as well as a vague small 
discal lunule. Beneath powdery, yellowish white, both wings with a 
discal lunule. 

Expanse, 25 to 29 mm. = 1 to 1.15 inches. 

Habitat.—Glenwood Springs, Colorado, in July; Garfield County, 
Colorado, 6,000 feet. 

Type.—Cat. No. 4147, U.S.N.M. 

This pretty little species has been taken by Mr. Bruce and also by 
Dr. Barnes; both sexes being before me. It is a sharply marked form, 


416 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXII. 


easily distinguished by the white thoracic disk and the prominent 
white spots on the inner margin, filling the median space at that point. 
It forms almost a half band of white, but does not quite reach the 
middle of the wing. When the specimen is spread the three white 
spots centering in the thorax give the creature a very characteristic 
appearance. Perhaps the insect would be a little better referred to 
Bryophila; but it is nearer in general appearance to the species of Chy- 
tonix, while not so broad winged. 


COPIBRYOPHILA, new genus. 


Hyes naked, large, hemispherical. Head moderate in size, distinct, 
not at all retracted, front conical and produced into a flat, wedge- 
shaped process which terminates in a broad, chisel-like tip. Vestiture 
sealy, forming no obvious tuftings. Palpi slender, cylindrical, reach- 
ing to or projecting a little beyond the frontal process. Antenne sim- 
ple in both sexes. Thorax rather short, subglobular, vestiture scaly, 
forming no obvious tufts, though there is a posterior bunching; pata- 
gia evident, though not uplifted. Abdomen reaching to or a little 
exceeding the anal angle of secondaries; slender, smoothly scaled. 
Legs well developed, tibiz: not spinose, the anterior not armed at tip, 
spurs of the middle and posterior tibiz long and prominent. Vestiture 
of under side scaly. Wings large; primaries long and proportionately 
somewhat narrow, the venation apparently normal; secondaries large 
and broad, veins 3 and 4, separating unusually close to the tip, vein 5 
scarcely even traceable. 

This is a curious genus for the Bryophilid series to which I feel com- 
pelled to refer it. Its narrow primaries and ample secondaries remind 
one of Hadenella, while the conic, armed front suggests the Acontiid 
series. The smooth scaly vestiture and the almost complete loss of 
vein 5 of the secondaries are considered Bryophilid, and as determining 
the location of the genus. 


3. COPIBRYOPHILA ANGELICA, new species. 


Ground color a smooth glistening gray brown, more or less mingled 
with whitish scales. Head and thorax without obvious markings. 
Primaries with all the markings fairly well defined. The median space 
darker than the rest of the wing, so that it seems a little contrasting. 
Basal line geminate, black marked on the costa only, within it the 
base brown. From that point to the transverse anterior line the basal 
space becomes paler and whitish at the transverse anterior line. This 
latter line is geminate, the outer portion blackish, oblique, rather feebly 
sinuate, the inner line indicated by a few brown scales. ‘Transverse 
posterior line geminate, not very well defined, irregular over the cell, 
where it is well curved outwardly, incurved beneath that point and a 
little better marked by the greater contrast between the median and 
subterminal spaces. Subterminal line irregular, whitish, without defi- 


No. 1203. NEW NOCTUID MOTHS—SMITH. 417 


nite margins, variably emphasized by preceding and following dusky 
shades. The terminal space is almost all dusky. The smoky shades 
in the subterminal spaces are broken and become lost toward the base 
of the wing. There is a Series of blackish terminal dots in the inter- 
spaces. The fringes are a little mottled with gray. The median shade 
line is distinct on the costa, darkens the space between the ordinary 
spots to almost blackish and becomes lost below that point. The clavi- 
form is of moderate size, outlined by black scales and filled with black- 
ish. Orbicular round, rather small, not very well defined; its outline 
formed by white scales. Ieniform kidney-shaped, of moderate size, 
outlined and partly followed by white scales, center with a dusky 
lunule which varies in size. Beyond the reniform the median space is 
paler and of the same shade as most of the subterminal space. Sec- 
ondaries even, smoky, fuscous a little glistening. Beneath smoky, 
more or less powdery, particularly on the secondaries on which there 
is a more or less distinct extra median line and a discal spot. In some 
cases similar spots are found on the primaries as well. 

Expanse, 20 to 23 mm. = 0.80 to 0.90 inches. 

Habitat.—Los Angeles, California, in October. 

Seven examples collected by Mr. Coquillett are under examination. 
There is not much difference in the specimens, except that some may 
be a little more contrasting than others. In some cases the median 
space is quite sharply defined and evenly brown, while in other cases 
the smoky powdering extends into the paler parts of the wing and 
lessens the contrast perceptibly. 

Type.—Cat. No. 4813, U.S.N.M. 


4. SETAGROTIS QUEBECENSIS, new species. 


Ground color pale, dirty, fuscous gray, powdery. Head and thorax 
concolorous, vestiture mixed scales and hair, tuftings not evident, 
patagia not marked. Primaries with the markings so obscure as to be 
traceable only with some difficulty, the lines only a little darker than 
ground. Basal line marked only on costa and below median vein. 
Transverse anterior line almost upright, single, a little outcurved in 
the interspaces. Transverse posterior line single, crenulate, the venu- 
lar points long; moderately curved over the cell, distinctly drawn in 
below. Subterminal line marked by a white powdering which is fairly 
well limited inwardly but extends irregularly into the terminal space. 
A very faint trace of a median shade which darkens the outer portion 
of the median space a mere trifle. Orbicular moderate, oval, decum- 
bent, a trifle paler than the ground and not otherwise defined. eni- 
form large, kidney-shaped, a trifle darker in shade, edged with a few 
gray scales. Secondaries smoky, paler, with a faint yellowish tint at 
base, fringes white. Beneath gray, powdery, primaries darker with a 
somewhat obscure discal spot and outer line; secondaries paler, with 
line and spot both prominent.

Expanse, 33 mm. = 1.32 inches. 
 Habitat.—Quebec, Canada. 

A single female, very like Carneades dissona in uneasicl appearance, 
and mistaken for it when first received. The generic reference in the 
absence of a male is not certain; but it is not likely that the discovery 
of that sex will necessitate a change. 


5. SETAGROTIS RADIATUS, new species. 


Ground color smoky gray, marked and irrorate with white, smoky 
brown and black. Head inferiorly yellowish, interantennal tuft also 
pale inferiorly. Palpi dusky at the sides. Collar inferiorly luteous, 
tipped with white and black scales. Thoracic tuftings well marked, 
tipped with white. Patagia white edged and with a black submar- 
ginal line. Primaries with the median lines obsolete, the subterminal 
line indicated by the darker terminal space and by a series of inter- 
spaceal black spots which show it to be very irregular. The veins are 
dusky, margined on each side by white scales, and the interspaces are 
dusky, the cell being darkest. There is a slender black basal streak 
which reaches nearly to the middle of the wing. The median vein is 
most prominently white marked and after this 3, 4, 6 and 7, which 
strongly indent the terminal space. The orbicular is obsolete. The 
reniform is a small, white lunule at the end of the cell. Secondaries 
white, with a smoky terminal line. Beneath white, powdery, else 
immaculate, the secondaries a little darker. 

Expanse, 35 to 36 mm, = 1.40 to 1.44 inches. 

Habitat._Nevada. 

Two males, very much alike, from Mrs. F. O. Herring, in only fair 
condition. The species is allied to vernilis and infimatis in type of 
maculation, but is not in the least like them in detail. It has so close 
a habital resemblance to Carneades nevada, however, that I had asso- 
ciated the two until a critical examination was made preparatory to 
description. 

Type.—Cat. No. 4787, U.S.N.M. 


CARNEADES Grote. 


In my Revision of the Agrotids! I recognized 108 species as referable 
to Carneades. Three years later, after having compared the British 
Museum collections, I catalogued? 109 names under that heading. - Since 
that time between fifteen and twenty new forms have been described, 
chiefly by myself, making about 125 nominal species of Carneades. The 
genus is one of the most difficult and unsatisfactory in the Noctuide 
because of the extent of the variation in certain species, and of the 
tendency to develop local types. In other words, species are forming

in a genus which seems peculiarly well adapted to the present con- 
ditions, and therefore dominant. Superficial differences are small at 
best, and, with only a small number of examples at hand, it is often 
simply impossible to say whether we have a mere variation or a distinct 
type. 

Gradually my collection has become filled with doubtful forms, each 
lot received yielding some specimen a little unlike any other in my 
possession. Of recent years Prof. C. V. Piper, of Pullman, Washington, 
has sent me long series of the common types in his region; Dr. William 
Barnes, of Decatur, Illinois, has sent me series taken at Glenwood 
Springs, Colorado; Mr. A. W. Hanham, of Winnipeg, Manitoba, has 
sent me material from that section, and Mr. F. H. Wolley Dod has sent 
me many examples from Calgary. Other collectors have contributed 
to a less extent, and I have rearranged the species, recognizing no less 
than 50 as worthy of new names. This brings the number of known 
forms to 175, and the end is not yet. I have yet more than a dozen 
uniques, different from each other and apparently from any of the old 
or newly described species; but because they are defective or are 
females, I have not felt justified in giving them names at present. 


6. CARNEADES PUGIONIS, new species. 


Ground color luteous, shaded with yellow and smoky fuscous. Head 
smoky, palpi yellow in front, and sometimes the head immediately 
behind them is of the same tint. Collar bright yellow at base, smoky 
fuscous above, the two shades divided by a narrow black line. Thorax 
squared, patagia relieved, margined with gray or yellowish, submargin 
blackish, disc gray, tuftings evident and gray or yellow tipped. Pri- 
maries contrastingly marked with yellow, gray, and smoky brown or 
blackish. Costal region bright yellow at base, gradually becoming 
more whitish toward the transverse posterior line. Inner margin below 
vein 1 yellow, shading to gray. A yellow shade begins above the clav- 
iform in the submedian interspace, and extends through it into the 
subterminal space. The subterminal space is gray or yellow beyond 
the transverse posterior line, sending rays or daggers through the 
terminal space to the outer margin on veins 3 and 4, and almost to the 
margin on veins 6 and 7. The terminal space, except as interrupted, 
is evenly dark or smoky, as is the cell, except the ordinary spots and 
such portions of the median and basal space as are not contrastingly 
yellow. Basal line wanting. Transverse anterior line evident as a 
black oblique mark in the median cell, as an outwardly curved line in 
the submedian interspace, and occasionally marked by a few scales 
below vein 1. Transverse posterior line broken, a little lunulate, chiefly 
marked by the difference in shade between median and subterminal 
Spaces, interrupted on the costa and in the submedian interspace. 
Subterminal line pale, preceded by a series of interspaceal black, sagit- 
tate spots and forming strong dents, cutting the terminal space on

veins 3, 4,6, and 7. The median vein is white, and below it, in the 
basal space, is a black shading which becomes diffuse inferiorly. Clav- 
iform black ringed, of good size, concolorous. Orbicular oblique, oval, 
often irregular, varying in size, complete if small, open to the costa if 
larger, outlined in black, narrowly annulate with white, center yellow- 
ish or gray. Reniform upright, rather narrow, filling the end of the 
cell completely, incomplete above and below, narrow kidney-shaped, 
defined by black scales and a narrow white annulus, centered with yel- 
low. Secondaries white, with a smoky terminal line from which a faint 
dusky shade may extend a short distance inward. Beneath, primaries 
smoky with a dark discal spot and white veins; secondaries white, only 
a little powdery, with a smoky outer line and a small discal spot. 

Expanse, 27 to 33 mm.=1.08 to 1.32 inches. , 

Habitat.—Denver, Colorado; Foothills (Bruce); Calgary, Canada, 
July 23, August 29 (Dod). 

Seven specimens, all males. The three Denver specimens are from as 
many different collectors, and Mr. Bruce probably collected his example 
near Golden. 

The species resembles my flavidens, and I had associated the two, 
until the occurrence of females of the older species caused a reexamina- 
tion of the series. In the new form the general color is lighter, the 
contrasts are much greater, and the secondaries are pure white. 

Type.—Cat. No. 4791, U.S.N.M. 


7, CARNEADES NEVADA, new species. 


Ground color ashen gray over fuscous. Head with an indefinite 
dusky frontal line, palpi brown at the sides. Collar gray tipped, with 
a black transverse line above the middle and below which there is a 
paler fuscous shading. Thorax squared, large, vestiture dense, mostly 
flattened hair, tuftings not well marked, partagia defined. The pri- 
maries appear somewhat strigate, owing to the absence of distinct 
transverse maculation, the paler median vein, and the tendency to 
define the other veins. Basal line marked only by a pale interruption 
of a black basal shade, which is not prominent and does not cross the 
basal space. Median lines marked on the costa only, though the loca- 
tion of the transverse anterior line is marked by the inception of the 
claviform, and the transverse posterior line may be found by careful 
search; but practically both are obsolete. Subterminal line obsolete. 
There is a series of black terminal spots from which blackish rays 
extend into the interspaces. A pale line at the base of the fringes. 
Claviform moderate in size, concolorous, outlined in black, pointed at 
the tip. Orbicular oval, elongate, decumbent, narrowly white-ringed, 
tending to an outward extension toward the reniform. Reniform small, 
broadly lunate, outlined by black scales, annulate with whitish. A 
somewhat paler shading extends obliquely from beyond the reniform to 
the apex, and a more indefinite lighter shade extends through the sub-

median interspace. Secondaries white, with a distinct, somewhat lunate 
blackish terminal line, and a dusky interline in the unusually long white 
fringes. Beneath white, gray powdered, both wings with small discal 
spots, and a series of distinct terminal lunules; primaries also with a 
partial exterior line. 

Expanse, 35 to 37 mm.=1.40 to 1.48 inches. 

Habitat.—Nevada. 

Three male specimens from Mrs. F. O. Herring, all of them a little 
rubbed, but very much alike so that all the details could be easily 
determined. The species belongs with hollemani in the pitychrous 
series, but differs obviously in the heavy quadrate thorax, the separate 
ordinary spots, and the pure-white secondaries. 

Type.—Cat. No. 4788, U.S.N.M. 


8. CARNEADES CONTAGIONIS, new species. 


Ground color a very pale yellowish or creamy gray, powdered with 
black scales. Head and thorax without ornamentation. Primaries 
with the median lines marked by black spots on the costa, and beyond 
that vaguely indicated. In the best-marked examples the basal line is 
black on the costa and has a short mark below the median vein. The 
transverse anterior line has a black costal dot and below the median 
vein there is a powdered single line, outwardly oblique and reaching the 
inner margin at nearly the middle of the wing. The transverse posterior 
line is marked by a black spot above the reniform on the costa, and then 
by short black marks on the veins, which give a course outwardly bent 
over the cell and then almost evenly oblique below. The terminal space 
is a little black powdered and in a vague way defines an irregular sub- 
terminal line. Where the powdering is slight there is no trace of the 
line apparent. Where the powdering is well marked the course of the 
imaginary line can be made out. There is a series of black terminal 
Junules. The fringes are concolorous with the rest of the wing. Orbic- 
ular an irregular black spot without defined margins, which is some- 
times covered by scales of the ground color. Reniform an indefined 
lunule, also without distinct margin, and occasionally more or less obso- 
lete. Secondaries in the males pure silky white, the veins a little darker 
marked in some specimens and with a distinct trace of a smoky shade 
at the base of the fringes. In the female they are somewhat smoky. 
Beneath white, a little black powdered with a more or less obvious discal 
spot on both wings—most obvious on the primaries—and sometimes 
with a broken exterior line. 

Expanse, 32 to 35 mm.= 1.28 to 1.40 inches. 

Habitat.—Glenwood Springs, Colorado, August 7, September 10, 
October 21 (Dr. Barnes); Garfield County, Colorado, 6,000 feet (Mr. 
Bruce); Verdi, Nevada. 

Twelve specimens are under examination and they resemble each 
other strongly. The ground color varies a little in shading, depending

upon the amount of yellow mixed with the gray. The amount of pow- 
dering on the surface is also a variable quantity, and sometimes it may 
be fairly weil covered with black atoms. Of the maculation, the costal 
dots, representing the beginning of the ordinary lines, are the most con- 
stant, and the dusky reniform comes next. The blackish orbicular may 
be added in better-marked specimens, and finally the lines may become 
fairly well indicated in the manner already described. The species 
belongs to the pitychrous section of the genus and is somewhat related 
to citricolor. The vestiture does not form evident tufts in any of the 
specimens before me, and in that particular there is a resemblance to 
some of the species allied to bostoniensis.

9. CARNEADES LOYA, new species. 


Ground color an even dark mouse gray. Collar with a broad, con- 
trasting, transverse band. Thoracic vestiture mixed scales and hair, 
patagia marked, tuftings evident. Primaries with the ordinary lines 
traceable only by black scales after close search, and they offer nothing 
distinctive as far as can be seen. Subterminal line marked by yellow 
scales forming irregular dots; preceded and followed by an irregular 
dusky shading. Orbicular moderate in size, ringed with yellowish, 
concolorous. Reniform elongate kidney shaped, narrow, ringed with 
pale yellow, centered with blackish. Claviform wanting. Secondaries 
yellowish smoky at base, smoky blackish at margins; veins and adiscal 
lunule blackish, fringes yellow at base, smoky centrally and whitish at 
tip. Beneath, sng? fuscous, powdery, both wings with a discal spot 
and a partly complete outer line. . 

Expanse, 36 mm. = 1.44 inches. 

Habitat.—High Sierras, California (Dr. Dyar). 

One female, a little crippled, but so obviously unlike all the known 
forms that I do not hesitate to describe it. It may be associated with 
bicollaris, from which, however, it differs obviously. There is a possi- 
bility that this may be the female of tocoyw (No. 25), but that would 
indicate a range of variation that I am not ready to admit without fur- 
ther evidence. Joya is the Indian name for the Sentinel, Dr. Dyar says, 
and the specimen bears his No. 11278. 


10. CARNEADES FLAVISCAPULA, new species. 


Ground color dull fuscous brown, with small gray powderings. Collar 
with a black line surmounted by gray scales, inferiorly with a reddish 
shade which, at the base of the wings, forms a rusty red tuft. Prima- 
ries very evenly dusty, the maculation not relieved, and traceable only 
by careful observation; yet it is all present. The course of the median 
lines is as usual, and too faintly marked to show characteristic features. 
Claviform indicated by dusky scales. Orbicular subquadrate, concol-. 
orous, defined by a few black scales and a narrow gray ring. Reniform 


No. 1203. NEW NOCTUID MOTHS—SMITH. 423 


moderate in size, kidney-shaped, traceable by black and gray scales, 
its outer middle invaded by a yellowish shading, which is the only 
obvious bit of color in the wing. Subterminal line fairly indicated by 
yellowish scales. Thoracic vestiture mixed flattened hair and scales, 
patagie and tuftings very fairly marked. 

Expanse, 32 to 33 mm. = 1.28 to 1.32 inches. 

Habitat.—New Mexico. 

Two males from the Hulst collection, in fair condition. This is an 
obscure form which from its lack of maculation should be referred to 
the pitychrous series, where it has no close allies. It is probably really 
nearer to the tessellata type, but with all the contrasts faded out. Per- 
haps its best place for ready recognition is with atomaris. 

Type.—Cat. No. 4810, U.S.N.M. 


11. CARNEADES EXCOGITA, new species. 


Ground color varying from mouse gray to fawn; that is, a soft, red- 
dish gray, in which the gray scales vary the tint. Head and thorax 
concolorous. Palpi black at sides. Collar with a distinct, black, 
median transverse line, narrowly edged above with paler. Vestiture 
consists of flattened hair, patagia evident, the divided crest and 
posterior tufts well marked in good examples. Primaries with all the 
markings obscure; the lines barely traceable and the ordinary spots 
hardly defined. Basal line indicated by geminate, dusky spots on the 
costa. Transverse anterior line geminate, in the best marked exam- 
ples the included space a little paler, outer defining line oblique, out- 
curved or angulated in the interspaces. Transverse posterior line 
barely traceable; apparently of the usual type. Subterminal line yel- 
lowish, irregular, more or less broken; sometimes marked by a slightly 
darker preceding shade; sometimes relieved by a dusky tint on both 
sides of it. Claviform indicated by scattered black scales in some 
specimens. Orbicular round or nearly so, moderate in size, incom- 
pletely outlined by black scales. Reniform concolorous or a trifle 
dusky, large, kidney-shaped, extending well below the cell, outlined 
by scattered dark scales and sometimes relieved by a few yellow 
scales. Secondaries smoky, paler in the male, a little lighter basally, 
fringes whitish, with dusky interline. Beneath whitish, powdery, disc 
of primaries smoky, a mére or less obvious common line and discal spot. 

Expanse, 32 to 37 mm. = 1.28 to 1.50 inches. 

Habitat.—Glenwood Springs, Colorado, July 3-29 (Dr. Barnes). 

Ten examples, evenly divided as to sex, varying only in tint and in 
the relative distinctness of the markings. In no case is it more than 
easily traceable, and sometimes the wings are practically immaculate. 

The species belongs to the velleripennis series and should be readily 
placed there. It has a vague superficial resemblance to Noctua pisci- 
_ pellis without the longitudinal markings. 

Type.—Cat. No. 4799, U.S.N.M.

12, CARNEADES EXCULTA, new species. 


Ground color a soft, dark, red-brown, overlaid by gray. Head and 
thorax immaculate; collar without a transverse line. Vestiture, 
slightly flattened hair, the tuftings indistinct. Primaries, at first 
sight immacnlate. The median lines indicated on costa by dusky 
spots and, under a lens, the transverse anterior line can be traced 
across the wing by a series of golden brown scales. Terminal space 
slightly darker, thus feebly indicating an irregular subterminal line. 
Ordinary spots marked by somewhat darker, lead-colored scales and, 
under the lens, outlined by golden brown scales. Secondaries paie, 
smoky yellow, darkening to smoky outwardly, fringes whitish yellow. 
Beneath whitish, powdery costal and outer margins darker, smoky. 

- Expanse, 33 mm.=1.32 inches. 

Habitat.—Northwest British Columbia. 

A single male, received from Mr. B. Neumoegen some years ego and 
never satisfactorily placed. It resembles excogita at first sight, but is 
more stumpy winged, lacks the prominent black line on the collar, and 
has the maculation much more completely obsolete. 


13. CARNEADES NAVULUS, new species. 


Ground color dull, powdery, ashen gray. Head and thorax immacu- 
late, collar with a dusky line just below tip; but this is obscure in most 
examples. Vestiture composed of long, flattened hair, anterior crest 
not obvious, posterior tufting fairly well defined, patagia not marked. 
Primaries with a rough, powdery appearance, none of the maculation 
well defined. Basal line geminate, smoky, interrupted. Transverse 
anterior line geminate, smoky, the two parts about equally obscure, 
outwardly oblique and rather evenly outcurved in the interspaces. 
Transverse posterior line obscure, fuscous, geminate on the costa, 
rather squarely bent over the cell, inwardly oblique and very even 
below this point. Subtermina] line irregular, punctiform, pale, some- 
times defined by a vague preceding shade, or a slight deepening of the 
terminal space, and sometimes wanting altogether. A series of black- 
ish terminal lunules, followed by a yellowish line at the base of the 
fringes. No obvious median shade or line. Claviform very small, and 
never completely outlined by blackish scales. Orbicular variable in 
size and shape, concolorous, outlined by black scales, complete only 
when it is smalland round. Reniform large, kidney-shaped, extending | 
below the cell, concolorous, incompletely black ringed. Secondaries 
dirty white in the male, with a somewhat defined, smoky, powdery 
outer porder, a smoky terminal line, and a discal lunule, the veins being 
alsosmoky; in the female they are smoky throughout, but become more 
whitish and transparent basally; discal lunule evident. Beneath, 
primaries gray, powdery, secondaries white, powdery along costa, all 
wings with a discal spot; no evident outer line. 


No. 1203. NEW NOCTUID MOTHS—SMITH. AP5 


Expanse, 35 to 40 mm.=1.40 to 1.60 inches. 

Habitat.—Placer County, California, in September. 

Nine males and three females from the U.S. National Museum, col- 
lected by Mr. A. Koebele. There is very little variation in the series, 
save such as is caused by a staining in either a moist cyanide bottle, 
or a softening jar containing too much carbolie acid. 

The form of the orbicular is the only changeable feature, and this is 
not alike in any two specimens. The species belongs to the pitychrous 
series and has some resemblance to cogitans, lacking, however, the 
black basal streak of the latter species. 

Tupe.—Cat. No. 4797, U.S.N.M. 


14. CARNEADES MEGASTIGMA, new species. 


Ground color dull luteous gray. Head, collar, and thorax immacu- 
late. Thoracic vestiture thin and slightly flattened hair, neither pata- 
gia nor tuftings well marked. Primaries rough with black powder- 
ings, the maculation obscure. Basal line geminate, marked by 
scattered scales only or obsolete. Transverse anterior line upright or 
nearly so, outcurved in the interspaces, geminate, but the inner element 
barely traceable. Tranverse posterior line geminate on the costa and 
to the angle opposite middle of cell, thence single, broken, hardly lunu- 
late, smoky, almost rigidly oblique to the margin. Subterminal line a 
little paler, powdery, somewhat defined by a preceding powdery shade, 
which may be absent. A very narrow, broken terminal line, followed 
by a yellow line at the base of the fringes. No obvious median shade; 
but in one specimen there is an indication that it might be expected 
in a large series. Claviform indicated by smoky scales. Orbicular 
very large, oblique, of the palest ground, defined at the sides only. 
Reniform large, broad, almost oblong or only feebly kidney-shaped, 
space between the spots forming a smoky V. Secondaries smoky, 
whitish toward base, with a discal lunule and veins dusky, fringes 
white. Beneath, primaries even, dull gray, secondaries more whitish, 
both with a vague discal spot. 

Expanse, 33 to 38 mm. = 1.32 to 1.52 inches. 

Habitat.—Kdge Calgary, August 24; Calgary, September 15, Can- 
ada (Dod). | 

Two females; one, the smaller, in good condition, the other lacking 
one primary and an abdomen, lost in the mail, but otherwise good. 
The smaller specimen is the more evidently marked and is quite pow- 
dery; the other is more even and, the powdering being absent, the 
markings are much less distinct. The species has the color of acornis, 
and may for the present be p!aced in that series. 

Type.—Cat. No. 4811, U.S.N.M. 


15. CARNEADES STIGMATALIS, new species. 


Ground color a somewhat light reddish brown, shaded with blackish 
scales along the veins and sometimes over the entire surface, so as to 


42.6 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXII. 


give a dull, dark, smoky brown appearance. Head and thorax immac- 
ulate. Vestiture, mixed with scales and flattened hair, the thoracic 
divided crest and posterior tuftings distinct, patagia relieved. Pri- 
maries with transverse maculation obsolete or barely traceabie. Basal 
line marked by smoky spots on the costa only. ‘Transverse anterior 
line, when traceable, almost upright, outcurved in the interspaces, 
irregularly so in the submedian interspace. Transverse posterior line, 
when traceable, bent over and close to the reniform, then oblique to 
the margin, even and inwardly diffuse. Subterminal line irregular, 
usually marked by yellowish scales and the somewhat darker terminal 
space; oczasionally also by preceding darker scales; rarely it is entirely 
wanting. A series of small terminal lunules, followed by a yellow line at 
the base of the fringes. Claviform small, narrow, pointed, usually well 
and completely defined; sometimes with a filling of yellow seales. Reni- 
form irregular, varying from almost round to obliquely oval, and in size 
from very small to quite large. It is defined by black scales, within 
which is a yellow annulus and the center is also a little powdered; in 
the smallest spot the center is entirely yellow, simply because the 
annulus takes up all the space inside the black ring. Reniform mod- 
erate in size, kidney-shaped, sometimes a little enlarged inferiorly, and 
extending below the cell. It is defined by black scales, within which 
is an annulus of yellow scales. The center of the spot is lightened 
superiorly by yellow scales and darkened inferiorly by leaden gray or 
blackish. Secondaries whitish, in the male with a narrow soiled outer 
border which is inwardly diffuse; in the female with a decided, smoky- 
yellow tinge, the dusky outer border broader. The veins are dusky 
marked, and there is a narrow, smoky, discal lunule. Beneath whitish, 
powdery, with a more or less indefinite common outer line and a discal 
spot on all wings. 

Expanse, 37 to 40 mm.=1.48 to 1.60 inches. 

Habitat.—Glenwood Springs, Colorado, August (Br. Barnes). 

One male and 5 females, all in fair condition. The species differs 
from its nearest allies in the somewhat well-marked veins and the 
obscurity of its ground color. There are several other points of differ- 
ence, making up altogether the sum of a good species belonging to the 
pitychrous series. 

Type.—Cat. No. 4805, U.S.N.M. 


16. CARNEADES TERMESSUS, new species. 


Ground color luteous gray, with a very even powdering of fine black 
scales that gives the insects a dusty or ashen appearance. Head and- 
thorax immaculate, palpi rusty yellowish in front. Thoracic vestiture 
consists of only slightly flattened hair, patagia not relieved, anterior 
crest feebly, posterior tuft distinctly evident. Primaries with the 
markings scarcely darker than the ground color, so that at a little dis- 
tance the wing seems immaculate. Basal line geminate, broken,

marked on the costa oniy. Transverse anterior line geminate, upright, 
the two parts more widely separated than usual, a rather sharp out- 
ward bend in the cell, another below the internal vein, and a feeble 
outcurve in the submedian interspace, giving it a Somewhat more than 
usual characteristic appearance. Transverse posterior line geminate, 
the inner line best marked and a little diffuse, as a whole evenly out- 
curved over the cell, and scarcely drawn in below. No median shade 
or line. Subterminal line practically obsolete, though its location 
can be discerned by slight differences in shading, notably on the costa, 
where a dusky subterminal shading a very little relieves the apex. A 
series of very small black terminal lunules. Claviform small, but as 
well indicated as any other feature. Orbicular moderate, oval, out- 
lined by smoky scales and a very little paler than the ground. Reni- 
form large, kidney-shaped, extending below the cell, concolorous, 
imperfectly outlined. Secondaries soiled whitish, with a narrow 
smoky outer border, a distinct terminal line and an evident, blackish 
discal spot. Beneath, primaries gray, secondaries white, both powdery 
and with an unusually distinct black discal spot on all wings. 

Expanse, 37 to 38 mm.—1.48 to 1.52 inches. 

Habitat.— Yellowstone Park, Wyoming, in August (Dr. Barnes). 

Two males, very much alike, and in good condition. The species 
belongs to the pitychrous series and is allied to mitis, than which it is 
larger, darker, without the reddish cast and with soiled instead of 
snowy secondaries. 


17,5 CARNEADES ENTERIDIS, new species. 


Ground color a very pale grayish yellow. Collar with a narrow black 
line, edged above with white scales. Thoracic vestiture scaly hair, the 
tufts and patagia fairly marked, a rosy flush on the disk. Primaries 
with the cell and terminal space, except apex, smoky; the markings 
smoky brown, all more or less broken. Basal line geminate, broken 
in the cell. Transverse anterior line geminate, prominently marked on 
the costa, obscure to the median vein, where it sends in a long inward 
tooth, then outwardly oblique and outcurved in the interspaces to the 
margin, the inner portion very feebly marked. Transverse posterior 
line geminate, abruptly bent on the costa over the reniform, thence 
very evenly parallel to the outer margin; inner part crenulated, send- 
ing out long teeth on the veins terminating in the venular dots of 
which the outer element of the line is composed. Subterminal bisin- 
uate, marked by a dusky preceding shade on the costa and below the 
pale apex, by the dark terminal space. A series of small terminal 
lunules is followed by a creamy yellow line at base of the fringes,which 
have double, gray interlines. A median shade crosses between the 
ordinary spots and a little outcurved below them, the space to the 
transverse posterior line being somewhat darker than the ground. 
Orbicular oblong, oblique, creamy gray, with a narrow white annulus

and a ring of black scales which is not complete superiorly. Reniform 
large, kidney-shaped, outlined by blackish scales which do not form a 
continuous line, an inner ring of smoky brown, leaving an annulus and 
central lunule of the paler ground color. Claviform pointed, moderate 
in size, outline smoky and broken. Secondaries white, with a smoky 
outer margin, which starts as a line at the anal angle and broadens to 
a band at the apex; veins and a small discal lunule also smoky. Be- 
neath white, powdery, both wings with a blackish discal spot, primaries 
with an outer line through the costal region. 

Expanse, 37 mm. = 1.48 inches. 

Habitat—Pullman, Washington (Piper). 

One male in fair condition. The species belongs probably to the 
pitychrous series, though the median shade is traceable. There is noth- 
ing sufficiently near to it to cause confusion, while the sharply defined 
dusky terminal space indicates the ochrogaster type of maculation. 


18. CARNEADES ATROPULVEREA, new species. 


Ground color dull smoky brown, densely and quite evenly powdered 
with black scales. Head and thorax immaculate, collar with a faint, 
darker, central line. Thoracic vestiture mixed scales and hair, patagia 
not relieved, tuftings feebly marked, thoughevident. |’ rimaries with all 
the markings obscure and no contrasts of any kind. Basal line gemi- 
nate, best marked by the yellowish scales in the included space. Trans- 
verse anterior line geminate, blackish, and with four small outcurves. 
Transverse posterior line geminate, evenly and not greatly outcurved 
over the cell, inner part crenulate, outer even and very feebly marked. 
Subterminal line scarcely paler, marked by the slightly darker terminal 
space, and an irregular, somewhat broken, dusky subterminal shading. 
A series of small terminal lunules, followed by a yellowish line at the 
base of the fringes. Median shade broad, blackish, diffuse, angulated 
below the reniform and making the most obvious bit of ornamentation 
onthe wing. Claviform barely indicated. Orbicular obsolete, or barely 
traceable by a few lighter scales. Reniform moderate in size, upright, 
kidney-shaped, vaguely defined by an incomplete yellowish annulus. 
Secondaries even, smoky fuscous, with paler fringes and a feebly defined 
smoky lunule. Beneath, primaries smoky, a little gray powdered, 
secondaries gray, powdered with smoky, with a broad, smoky outer band 
and discal lunule. 

Expanse, 37 mm. = 1.50 inches. 

Habitat.—Denver, Colorado, October 10; Fort Collins, Colorado 
(Gillette). : 

Three females, one of them rubbed and otherwise imperfect. Larger 
and narrower winged than intrita, with all the maculation obscured 
and the median shade unusually evident. The orbicular is almost 
entirely obsolete and the reniform is very incompletely outlined. It is 
to be regretted that no male was received.

19. CARNEADES COMPRESSIPENNIS, new species. 


Ground color dull smoky red brown, roughly powdered. Front 
brown. Collar with a black median line, below which it is brown. 
Thoracic vestiture flattened hair, some of it tipped with gray, patagia 
and tuftings fairly marked. Primaries with the vestiture rough and 
powdery in appearance, all the markings fragmentary, cell filled with 
richer brown around the ordinary spots, costa at base, gray powdered. 
Basal line geminate, broken, black, included space gray. Transverse 
anterior line geminate, black, inner portion less evident, included space 
paler, inwardly bent on the median vein, outwardly oblique and out- 
curved in the interspaces below. A black shading below the median 
vein connects the inward tooth of transverse anterior line with the 
outward bend of basal. Median vein obscurely pale powdered. Trans- 
verse posterior line geminate, inner portion lunulate, outer even, 
included lunules reddish. Subterminal line yellowish powdery, a little 
irregular, marked by a preceding brown shade, the powdering out- 
wardly diffuse, lightening the apex and sometimes the terminal space. 
A series of small terminal lunules, followed by a yellowish line at the 
base of the fringes. No obvious median shade. Claviform moderate 
in size, outlined by black scales. Orbicular irregular, subquadrate, 
oblique, narrowly pale ringed, center pale powdered. Reniform moder- 
ate in size, rather narrow, kidney-shaped, annulate with yellowish 
gray, the center pale powdered. Secondaries evenly smoky in both 
sexes, fringes with a yellow line at base. Beneath dull gray, powdery, 
with very faint ordinary spots and only a trace of an outer line. 

Expanse, 33 mm. = 1.32 inches. 

Habitat.—Yosemite, California, male, Dr. Dyar, No. 9617; female, 
special locality and source not marked. 

One male and one female only, very much alike and in fair condition. 
The species is allied to intrita Morrison, but is much more powdery as 
well as somewhat broader winged. 


20. CARNEADES FALERINA, new species. 


Ground color pale, whitish luteous with deeper luteous shadings and 
smoky powderings. Head and thorax concolorous; palpi dusky at the 
sides, color with rather an indefinite smoky median line, best marked 
in the female. Thoracic vestiture mixed with scales and flattened hair, 
patagia marked, tuftings evident though not prominent. Primaries 
with the markings all present and recognizable, but not strongly 
marked or contrasting, the lines luteous or smoky. Basal lines gemi- 
nate, marked by smoky spots on the costa and below the median vein. 
Transverse anterior line geminate, inner portion less marked, upright 
or a little oblique outwardly, interrupted in the costal space, with smail 
outcurves in the interspaces. Transverse posterior line geminate on 
the costa, the outer portion lost below the costal space, inner part

crenulate, evenly outcurved over the cell and just a little drawn in 
below. Subterminal line of the ground color, irregular, almost angu- 
late, marked by the darker terminal space and by a preceding dusky 
shade, which is always distinct on the costa, but broken or even 
obsolete below that point. A series of small, brown terminal lunules. 
Claviform feebly indicated by darker scales, variable in size. Orbicu- 
lar round, oval, or elongate, variably evident, outlined by black or 
dusky scales, and in the female with a dusky central shading. Reni- 
form upright, moderate in size, kidney-shaped, incompletely and imper- 
fectly outlined, the center dusky. There is also a diffuse, darker, lute- 
ous median shade, which darkens a trifle the outer portion of the 
median space and may be scarcely noticeable. In one specimen the 
ordinary spots are normally separated, in another the orbicular almost 
touches the reniform, in the third the spots join and seem almost con- 
fluent. Secondaries white in both sexes, the veins a little yellowish, a 
broken, smoky, terminal line and a vague dusky outer shading. 
Beneath white, a little powdery, with a dusky discal spot and an incom- 
plete, powdery outer line on all wings. The fringes, especially on 
secondaries, are unusually long. 

Expanse, 37 to 40 mm. =1.48 to 1.60 inches. 

Habitat—Glenwood Springs, Colorado, August and October (Dr. 
Barnes); Nevada (Mrs. Herring). 

Two males and one female, all different, yet I believe representing 
one species only. The long fringes to the secondaries, the plump, 
heavy body, and the rather lengthily serrated male antenne suggest a 
Porosagrotis, but the genitalia agree with the Carneades type. In the 
male type the smoky powdering is quite evenly distributed, except in 
the subterminal space, and all the maculation is obscure. The male 
cotype is less powdery and all the markings are in consequence better 
defined. The female type while less powdery is quite as obscurely 
marked as the first-mentioned male. More material would be very 
desirable to fix the range of variation in this species. 

Type.—Cat. No. 4785, U.S.N.M. 


21. CARNEADES VALLUS, new species. 


Ground color very pale gray, over a pale luteous base. Palpi yellow 
in front, dusky at the sides. Beneath dusky. Vestiture, thin, hairy, 
somewhat divergent. Top of head and base of collar whitish, the lat- 
ter tipped with yellowish hairs. Thoracic vestiture forming no obvi- 
ous tufts; but posteriorly the hair is tipped with yellowish. Primaries 
quite densely black powdered, darkening the wing beyond the trans- 
verse anterior line. All the lines single. Basal line blackish, distinct, 
reaching the submedian vein, bent on the median. Transverse anterior 
line smoky, a little outcurved, with three interspaceal outcurves, of 
which that in the submedian interspace is the longest. Transverse 
posterior line obscure, crenulated, unusually close to the outer margin,

broadly outcurved over the cell, then parallel with the outer margin. 
Subterminal line barely indicated by a series of dusky spots. Median 
shade broad, diffuse, vague, a little outwardly bent at its middle. 
Orbicular round, moderate in size, a little paler than the ground, but 
not otherwise defined. Reniform moderate in size, indefined and incom- 
plete, a little paler than ground, but with a central dusky crescent, 
which is diffuse and leaves the lower part of the spot scarcely separ- 
able from the ground. No trace of claviform. Secondaries smoky, 
pale gray, scarcely darker outwardly, veins marked, and end of cell 
indicated by a narrow lunule. Beneath, pale yellowish gray, silky, 
both wings with an obscure outer shade line and a vague discal spot, 
secondaries with a blackish line through the cell from base almost to 
the lunule. 

Expanse, 40 mm.=—1.60 inches. 

Habitat. Laggan, British Columbia, 5,000 feet, September 9 (Bean). 

A single female only, in fair condition. The species is allied to 
bostoniensis, but is much more obscure and powdery. It has that 
peculiar pallid, washed-out appearance that is characteristic of northern 
mountain forms, as well as the loose, woolly vestiture. I know of noth- 
ing with which this might conflict. 


22. CARNEADES SESSILE, new species. 


Ground color an even, dull, smoky gray, without marxed contrasts 
of any kind. Head and thorax concolorous, the palpi tipped with yel- 
low. Vestiture hairy; but somewhat flattened, not loose or diverging. 
Collar well relieved, patagia not differentiated, tuftings barely indi- 
cated in the female, fairly suggested in the male. Primaries with a 
faint reddish shading, best marked in the male, very evenly and not 
densely black powdered. Basal line geminate, broken, blackish, not 
well marked. Transverse anterior line smoky, geminate, the two parts 
almost equally well defined, almost upright to the median vein, a little 
outcurved below, and a longer, outward loop below the internal vein. 
Transverse posterior line geminate, inner portion evenly outcurved over 
the cell, lunulate and a little incurved below; outer part obscure, smoky, 
even. Subterminal line vaguely traceable, really visible only near the 
costa, where it is marked by the contrast between the apex and a 
Slightly darker subterminal shading. Median shade diffuse, rather 
broad, slightly darker than the ground color and a little darkening the 
cell between the ordinary spots. Claviform small, concolorous, com- 
pletely outlined in smoky. Orbicular irregularly oval, decumbent, out- 
lined in black, of the ground color or avery little paler. Reniform large, . 
broad, irregular, extending below the median vein, outlined by black 
scales, concolorous or a very littie paler. There is a narrow, black, bro- 
ken, terminal line, followed by a yellowish line at the base of the fringes. 
Secondaries smoky yellowish, paler at the base, in the male rather 
whitish, with a smoky discal lunule and a white fringe which, in the

female, is somewhat contrasting. Beneath whitish, powdery, disk of 
primaries smoky, darker in the female; no outer line; but a discal spot 
on all wings. 

Expanse, 40 mm. (male) to 42 mm. (female) = 1.60 to 1.68 inches. 

Habitat.—Colorado (Bruce); Hall Valley, August (Barnes). 

One male (Bruce) has been in my collection for years; the female has 
been recently received from Dr. Barnes. The species is much more 
obscure throughout than messoria, and the hairy vestiture throws it 
rather to the bostoniensis series, where it does not conflict with any 
described species. 

A third specimen, also from Colorado, near Denver, I refer doubtfully 
to this species. It expands only 35 mm., is more sharply marked 
throughout, and the subterminal space is uniformly darker, relieving a 
subterminal line which is distinetly toothed on veins 3 and 4. Thesec- 
ondaries are also more whitish and the smoky outer border is better 
defined. 


23. CARNEADES RELAXUS, new species. 


Ground color pale, smoky fuscous, with a slightly reddish tint. 
Head and thorax concolorous. Palpi tipped with yellowish, dusky at 
the sides. Collar with an incomplete brown line near the tip. Tho- 
racic vestiture of flattened hair, patagia hardly relieved, tuftings just 
indicated. Primaries without contrasts, the lines smoky rather than 
blackish. Basa] line geminate, indicated on the costa and submedian 
interspace only. Transverse anterior line geminate, inner line marked 
on costa only, outer a little oblique and feebly outcurved in the inter- 
spaces. ‘Transverse posterior line geminate, outer line lost below the 
cell, inner crenulated, as a whole outeurved over cell, and then almost 
parallel with the outer margin. Subterminal line pale, irregular, with 
small teeth on veins 3 and 4, relieved by a continuous, dusky, preced- 
ing shade, the terminal space being also more or less dusky. <A series 
of brown, terminal lunules. Median shade vague, diffuse, barely 
traceable. Claviform absent in the specimens before me, but I should 
expect to find indications of it in the species. Orbicular round or oval, 
outlined by black or smoky scales, concolorous, center with or without 
dusky powderings. Reniform large, kidney-shaped, extending a little 
below the cell, outlined by black scales, center more or less dusky 
inferiorly. Secondaries very pale yellowish, becoming smoky out- 
wardly; fringes whitish, discal lunule present. Beneath whitish, 
powdery, a more or less obvious common outer line, and all wings with 
discal spots. 

Expanse, 38 mm. (male) to 39 mm. (female)— 1.52 to 1.56 inches. 

Habitat.—San Francisco and Sierra Nevada, California. 

One male and one female, and there is just a little doubt as to their 
really being sexes of the same species; line for line they are the same, 
and such little differences as occur are well within the range of varia- 


No. 1203. NEW NOCTUID MOTHS—SMITH. 433 


tion in allied species. Nevertheless there is a vague dissimilarity 
which prevents my marking the female as a type, though it is the 
better example of the two. 

At first sight this closely resembles sessile and is, indeed, its near 
ally; but it is paler, with a more yellowish tint throughout; there is no 
obvious claviform, the subterminal line is entirely obvious, and the 
transverse posterior line is crenulated and practically single below the 
cell. 

Type.—Cat. No. 4800, U.S.N.M. 


24. CARNEADES LUTEOSITUS, new species. 


Ground color dull luteous, with rusty shadings on thorax and prima- 
ries. Head and thorax else immaculate. Vestiture hairy, patagia 
marked, tuftings obscurely indicated; thorax as a whole small in com- 
parison with the long abdomen, which considerably exceeds the hind 
angle of the secondaries in both sexes. Primaries with ornamentation 
well defined. Transverse lines all single, broad, a little diffuse. Basal 
line distinct. Transverse anterior line upright, a little outcurved in 
the submedian interspace. Transverse posterior line with a broad, 
even outcurve over the cell, oblique or a little incurved below, with 
little, sharp points on the veins. Subterminal line marked by a dusky 
preceding shade, very even, the subterminal space sometimes with pale 
scales, lightening it perceptibly. A series of narrow, dusky, terminal 
lunules. Median shade not obvious in the male, in the female dusky, 
diffuse; oblique between the ordinary spots and parallel with transverse 
posterior line below. Orbicular large, round, without defining line, 
save the contrast between its paler shade and the surrounding ground. 
Reniform marked chiefly by a smoky lunule with irregular paler edges. 
Claviform wanting. As a whole the basal space is a little paler, some- 
what gray powdered; the median space is somewhat the darkest and 
shaded with rusty and blackish. Secondaries dark smoky, paler at 
base, with a blackish lunule and yellow fringes. Beneath paler red- 
dish luteous; all wings with a discal lunule and an incomplete outer 
line. 

Expanse, 35 to 36 mm. = 1.40 to 1.44 inches. 

Habitat.—Hall Valley, Colorado, July 24 to 30 (Dr. Barnes). 

One male and one female, both in good condition. In maculation the 
species resembles bifasciata, but in color it is totally different, and, 
indeed, also in the course of the lines. The male is somewhat aberrant 
for a Carneades in having the antennal joints only a little marked and 
the lateral tuftings short and feeble. 


25. CARNEADES TOCOYZ, new species. 


Ground color a dull, pale, brick red, overlaying a yellowish base. 
Collar with a feebly marked central line. Thoracic vestiture flattened 
hair, tufts obvious. Primaries with the marking only a little darker,

not contrasting, the included space in the geminate median lines 
lightened by yellow. Basal line brown, geminate, best marked by the 
included yellow shade. Transverse anterior line almost upright, 
broadly outcurved in the interspaces. Transverse posterior line 
geminate, outer part faint, even; inner crenulate, brown, as a whole | 
evenly and not greatly outcurved over the reniform, evenly oblique 

below. Subterminal line irregular, broken, paler, marked by a slightly 
darker preceding shade, the terminal space marked with dusky in the 
veins. Median shade line narrow, blackish, a little irregular, as a 
whole a little outeurved. A series of black terminal lunules, beyond 
which is a yellow line at the base of the fringes. Claviform barely 
indicated. Orbicular small, round, outlined in yellow. Reniform 
moderate in size, kidney-shaped, rather narrow, outlined in yellow, 
filled with blackish. Secondaries yellowish at base, becoming smoky 
outwardly, veins and a discal lunule also smoky. I ringes yellow at 
base, whitish at tip, with a smoky centralline. Beneath dull yellowish, — 
powdery, primaries with a diffuse blackish oval, representing the pale 
outline of the reniform above; secondaries with a small black discal 
lunule. . 

Expanse, 37 mm.= 1.48 inches. 

Habitat.——High Sierras, California (Dr. Dyar). 

A single male in fair condition, No. 11277. The species has no very 
close allies, but may come at the end of the bostoniensis, or at the head 
of the messoria series. In either case it is readily distinct. 

Tocoya, according to Dr. Dyar, is the Indian name for the north dome, 
near where this insect was taken. 


CARNEADES MESSORIA Harris. 


In this species all the normal maculation is well written, and all the 
usual spots are evident. Basal, transverse anterior and transverse 
posterior lines are obviously geminate, and while the inner part of the 
transverse anterior and outer part of the transverse posterior line are 
less obvious, and may be even somewhat obscure, there is never any 
doubt of their actual presence. The median shade is equally obvious 
in most cases, and is sometimes as well marked as the median lines, 
though always a little diffuse. It is sometimes almost upright, but as 
a rule is a little outwardly oblique from the costa to the inferior margin 
of the reniform, and from that point is nearly upright to the inner mar- 
gin, which it reaches close to the transverse posterior line. The 
transverse anterior line is a little oblique outwardly, with three main 
interspaceal outcurves, of which that in the submedian interspace 1s 
broadest, but as a rale not quite so much exserted; that below the 
submedian vein is always most bent outwardly. The transverse pos- 
terior line is very evenly bent over the cell, and is then oblique below, 
hardly incurved in any case, unless exceptionally. The inner part of 
the line is crenulate, and the outer portion crosses the tips of the 
points, leaving inclosed a series of lunules of the ground color ora 


NO. 1203. NEW NOCTUID MOTHS—SMITH. 435 


little paler. The subterminal line is always obvious and usually a 
little paler; but it may be concolorous and only defined by the some- 
what darker terminal space. There may be a preceding dark or dusky 
shade and this may be broken; but it never forms sagittate spots or 
dashes, and it is never prominent. In no ease is the terminal space 
paler than the subterminal, or as pale as the lighter parts of the wing. 
There is no basal dash or longitudinal mark of any kind. The claviform 
is narrow, concolorous, very rarely completely outlined, sometimes a 
mere blackish lunule indicating its tip; sometimes very short, some- 
times extending to the middle of the median space; often very obscure, 
but always traceable in good specimens. The orbicular is of good size, 

black ringed, varying in shape from round to irregularly oval, ofttimes 
oblique. There is often a paler annulus within the black ring, and the 
entire spot is usually even and a trifle paler than the ground color of 
the wing; rarely it is just a little powdery, but is never dark centered. 
The reniform is always large, kidney-shaped, usually a little oblique, 
outlined by blackish seales, and within this a paler annulus which is 
only a slighter paler tinge of the ground and never prominent. The 
interior is also a little pale, but with a dusky powdering which yet 
leaves the spot as a whole paler than its immediate surroundings. The 
ground color of the primaries is a graying luteous with blackish pow- 
derings and little if any trace of red or brown. The cell between and 
beyond the ordinary spots is always a little the darkest portion of the 
wing, and sometimes the space between the median shade and trans- 
verse posterior line is also involved; but there are never any strong 
contrasts. The secondaries are whitish, with a faint yellow tinge, 
Somewhat more pronounced in the female, and there is a smoky outer 
border, varying in width, always undefined, very narrow i the male, 
sometimes darkening almost half the wing in the female, especially 
along the inner margin. 

The collar has always a black or blackish transverse median line. 

The expanse varies from 32 to 42 mm., but the great majority of 
examples will be from 35 to 37 mm., without much difference in favor of 
the female. 

The 25 males and 14 females under observation are distributed as to 
locality from the Atlantic to the Pacific, and there is no geographic 
variation observable. 

The species has been thus carefully described as to its essential char- 
acters that others allied to it, actually or superficially, might be differ- 
entiated comparatively; and it is especially useful for this purpose 
because it is at once the most abundant and the most widely distributed 
of the forms, so that all collectors are most likely to possess examples. 


26. CARNEADES INCUBITA, new species. 


Is a close ally of messoria, from which it differs at first sight in the 
darker, blackish gray, ground color. In the female there is hardly 
a trace of the pale luteous ground, which is, however, easily seen in the 


A386 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL.XXI, 


male. The general type of maculation is the same; but in the new 
species it is darker, more clearly written, while a white powdering on 
the costal cell and along the median vein gives a somewhat character- 
istic appearance. The cell around the ordinary spots is evidently 
darker and the centers of the spots themselves are dusky. This, in the 
case of the orbicular, serves as an easy method for ready differentia- 
tion, for in messoria this spot is never darkened; in the new form it is 
obviously dusky in every case, leaving a pale annulus inside the black 
defining ring. The transverse line in the collar is much more feebly 
marked than in messoria and the secondaries have the dusky shading 
blackish, rather than yellow tinged. 

Altogether, while the individual differences are slight, the sum of 
the characters and their uniformity in the series before me indicates a 
good species. 

Expanse, 35 to 42 mm.= 1.40 to 1.68 inches. 

Habitat.—Pullman, Washington, in August (Piper); Santa Cruz 
Mountains, California (Hhrhorn). 

Five males and six females. 

Type.—Cat. No. 4803, U.S.N.M. 


27. CARNEADES TERRENUS, new species. 


Ground color a dull, luteous, gray brown, irrorate with coarse black 
scales. Collar with a blackish transverse line. Primaries with all the 
markings present and of the messoria type. ‘Transverse anterior line 
more nearly upright and the outcurves less marked. Transverse pos- 
terior line practically as in messoria. Subterminal line vague, broken, 
preceded by a more or less evident broken, blackish shade, which is 
never contrasting. Terminal space not darker than the ground. 
Median shade very vague and diffuse, sometimes scarcely traceable. 
Claviform never complete, usually marked by a few scales only, often 
obsolete. The ordinary spots much as in messoria, save that they are 
less relieved and the reniform is smaller, without central powderings. 
The cell between the ordinary spots is dusky; but this shade rarely 
extends beyond the reniform or into the median space. Secondaries 
even, smoky fuscous in both sexes, a little darker in the female. 

[Eixpanse, 35 to 40 mm.= 1.40 to 1.60 inches. 

Habitat.—Pullman, Washington, June and July (C. V. Piper). 

A series of 12 males and 5 females is quite uniform in general 
appearance, obviously distinct from messoria by the darker, coarsely 
powdered primaries, on which the usual maculation is obscure, and by 
the uniformly dusky secondaries. The new species also averages 
larger than its ally, the majority of the examples attaining 38 mm. 

Type.—Cat. No. 4802, U.S.N.M. 


28. CARNEADES TERRITORIALIS, new species. 


Ground color a very light reddish gray, tending to mouse gray, even, 
hardly powdery. Head and thorax immaculate, collar with a dusky

central line. Vestiture mixed seales and hair, patagia evident, anterior 
crest and posterior tuft distinct. Primaries with all the normal messoria 
markings present, very neatly and finely written. Basal line geminate, 
black, very distinct. Transverse anterior line geminate, inner part tend- 
ing to become lost, outer fine, blackish, as a whole outwardly oblique, 
with strong outcurves in the interspaces, the one below vein 1 being 
the longest. Transverse posterior line geminate, outer portion even 
and tending to become lost, inner slender, crenulate, blackish; as a 
whole the line is abruptly bent on the costa and after a gentle curve 
over the cell it is almost straight to the hind margin. Subterminal 
line pale, a little irregular, broken, with somewhat longer dents on veins 
3 and 4, marked on the costa by a dusky subterminal shade and below 
the clear apex by the dusky terminal space. There is a distinct though 
narrow black terminal line, somewhat thickened in the interspaces and 
followed by a narrow yellow line at the base of the fringes. Median 
shade smoky or blackish, rather narrow, margins a little diffuse, form- 
ing an obtuse angle against the reniform. Orbicuiar always traceable, 
concolorous, never completely outlined, rather small. Orbicular mod- 
erate or small, round or a little ovai, narrowly black ringed, concolor- 
ous or a little paler. Reniform large, kidney-shaped, rather narrow, 
extending a little below the cell, not well defined except at the sides, 
incompletely pale ringed, center somewhat dusky. Secondaries in the 
male white, with an iridescent smoky tinge, especially toward the edges; 
veins, very small discal spot and outer margin narrowly smoky; in the 
female, transparently smoky, whitish toward base, else as in the male. 
Beneath white, disc of primaries smoky, a smali, common discal dot, 
primaries often with an incomplete exterior line which is sometimes also 
begun on the secondaries. 

Expanse, 32 to 36 mm. = 1.28 to 1.44 inches. 

Habitat.—Denver, October 12; Salida, August 10 (Oslar); Glenwood 
Springs, October 1-7 (Barnes), all in Colorado; Pullman, Washington, 
September 24 (Piper). 

Two males and three females are before me. The species resembles 
and is no doubt confused with messoria, but it is much more neatly 
marked, more even in ground color, with smaller ordinary spots and 
altogether paler secondaries. The species varies in ground color and 
in the relative distinctness of its ornamentation, but can always be 
separated from messoria by the characters given, when the two are side 
by side.

. blackish, marked only on the costa and submedian interspace. Trans- 
verse anterior line geminate, broken, brown, inner part of line tending 
to become lost; outwardly oblique, outeurved in the interspaces, a long 
bend below the submedian reaching nearly to the middle of the margin. 
Transverse posterior line geminate, fine, brown, inner part crenulate, 
outer even and scarcely marked; as a whole very evenly outcurved over 

- the cell and evenly obliquebelow. Subterminal linemarked by the some- 
what more dusky terminal space except at apex, where a dusky shade 
precedes it, the contrasts being very feeble. Terminal line fine, black, 
continuous, followed by a yellow line at the base of the fringes, which 
areinterlined with brown. Median shade feebly marked, almost upright, 
slightly darkening the space between the ordinary spots. Claviform 
indicated by a few scattered, blackish scales. Orbicular rather large, 
oval, decumbent, concolorous, outlined at sides by black scales. Heni- 
form moderate in size, kidney-shaped, extending a little below the cell, 
incompletely outlined in black scales, with an incomplete pale annulus, 
the center dusted with lead-colored scales. Secondaries smoky whitish, 
paler at the base, veins dusky, discal lunule small, terminal line brown, 
fringes whitish. Beneath, whitish, powdery, disc darker, secondaries 
with a feeble discal lunule. 

Expanse, 34 to 36 mm.—1.36 to 1.44 inches. 

Habitat.—Alameda County, California, September. 

Two female specimens from the U. S. National Museum, collected by 
Mr. A. Koebele. The species is of the messoria type, but very obscure, 
the markings not relieved against the reddish-gray backing. In the 
slender median lines it resembles territorialis, than which it is more 
red and decidedly more obscure. 

Type.—Cat, No. 4792, U.S.N.M. 


30. CARNEADES ITODES, new species. 


Ground color a very pale luteous, washed with light reddish. Head 
and thorax concolorous, palpi smoky at the sides, collar with a smoky 
transverse median line. Thoracic vestiture nixed scales and flattened 
hair, patagia marked, anterior crest and posterior tufting well defined. 
Primaries very even in tint, all the markings smoky brown, quite evi- 
dent; but not contrasting. Basal line geminate, complete, included 
space alittle paler. Transverse anterior line geminate, inner portion not 
so well marked, oblique, with 4 subequal and not strongly marked out- 
curves. Transverse posterior line geminate, outer line vague, even, 
inner crenulate, included space a little paler. Asa wholeitis abruptly 
bent over the cell and a little incurved below. Subterminal line of the 
ground color, defined by the slightly darker terminal space and a dusky 
preceding shade, which is irregular, but continuous and best marked on 
the costa. A series of distinct, dusky, narrow, terminal lunules. 
Median shade rather narrow, diffuse, outwardly oblique and darkening

the space between the ordinary spots, evenly oblique inward and well 
removed from the transverse posterior line trom the lower angle of the 
reniform. Claviform wanting, but there is a narrow and_ scarcely 
defined yellowish mark occupying its place and extending to the median 
shade. Orbicular round or nearly so, moderate or small, annulate with 
yellowish, centered with the ground color, darkened by a few dusky 
scales. Reniform moderate in size, kidney-shaped, extending a little 
below the cell, outlined in yellowish, filled with leaden: gray or smoky. 
Secondaries yellowish white, darkening a little at the outer border to a 
distinct dusky terminal line; veins and a narrow lunule also a little 
darker. Beneath white, with a glistening yellowish tint, more or less 
powdery, primaries with anu obvious discal lunule, secondaries with a 
small dusky spot. 

Expanse, 37 to 40 mm. = 1.48 to 1.60 inches. 

Habitat.—Arizona (Dr. Barnes). 

Three good females, with no more definite locality than above given. 
The species is easily different from any heretofore described, though 
resembling at first a reddish canis. The vestiture here is scaly rather 
than hairy, however, and the very evenly marked ornamentation is 
characteristic rather of messoria, near which the new form must be 
_ placed. 

31. CARNEADES LAGGANZE, new species. 


Ground color dull, dark, ashen gray, with fuscous powderings. 
Collar gray and dark powdery, with a black, median, transverse line. 
Thoracic vestiture mixed seales and flattened hair, somewhat loose, 
patagia well marked, margins edged with black scales, tuftings dis- 
tinct. Primaries with the markings well written, blackish, not 
strongly contrasting. Basal line geminate, distinct, dentate. Trans- 
verse anterior line geminate, outer portion broad and black, inner nar- 
row and smoky, outwardly oblique, irregularly outcurved in the inter- 
spaces, the longest curve below vein |. Transverse posterior line 
geminate on the costa, below which the outer portion is lost, the inner 
smoky, lunulate, with long outward venular points, only a little out- 
curved over cell, parallel with outer margin. Subterminal line indi- 
cated by irregularly placed paler scales, relieved by darker preceding 
scales. A series of blackish terminal lunules, followed by a pale line 
at base of fringes. Median shade line oblique between the ordinary 
spots and somewhat darkening the cell, thence, from the inferior angie 
of the reniform, close to and parallel to transverse posterior line, the 
intervening space becoming slightly dusky and giving the effect of a 
narrow darker band. Claviform small, very narrowly outlined by 
black scales. Orbicular a little paler than ground color, without pow- 
derings, of good size, narrowly black ringed. WReniform kidney-shaped, 
rather narrow, not powdery, not extending below cell, very narrowly 
black ringed. Secondaries even smoky gray, the veins hardly darker,

fringes paler with a yellow line at base. Beneath, dull gray, with a 
small dusky discal spot and a broad, diffuse, darker outer band, which 
is complete on both wings. 

Expanse, 33 mm.=1.32 inches. 

Habitat.—Laggan, British Columbia (Bean). 

A single perfect male. The species is evidently allied to the messoria 
series, but has broader, more pointed primaries than usual, and the 
antennal processes are very small, the tufts of soft hair rather than 
bristles. These characters, as well as the dentate basal, and unusually 
irregular transverse anterior lines, will serve to characterize the 
species. 

32. CARNEADES ONTARIO, new species. . 


Ground color dull, smoky fuscous. Head with a brown transverse 
line. Collar with a dusky transverse shade. Thoracic vestiture scaly 
hair, rather loose, neither tufts nor patagia well marked. Primaries 
rather powdery, median space a little darker, transverse lines blackish, 
not contrasting. Basal line geminate, broken in the cell. Transverse 
anterior line geminate, almost upright, irregular in the interspaces, 
inner part much less distinct than outer. Transverse posterior line 
geminate to the outcurve, then single, crenulate, alittle drawnin. Sub- 
terminal line indicated by a few pale scales and a vague preceding shade 
which is fairly obvious in the costal region. A series of brown termi- 
nal lunules, followed by a very narrow pale line at base of fringes. 
Median shade line vaguely indicated. Claviform absent in the speci- 
men. Orbicular indicated by a diffuse, undefined, pale blotch. Reni- 
form marked by a blackish, oblong blotch, partly bounded by paler 
scales. Secondaries smoky, with a yellow tinge basally, veins and a 
discal lunule blackish. Fringes whitish. Beneath, primaries smoky, 
secondaries gray, both powdery, with a discal blotch and a broad diffuse 
outer shading. 

Expanse, 33 mm. = 1.32 inches. 

Habitat.—Sudbury, Ontario. 

A single male, source not noted on the specimen. It is an ally of 
laggane, with similar wing form and general habitus, but much darker ~ 
throughout, the antenne having the joints much better marked. In 
fact, while at first sight the species are obviously similar, careful com- 
parison shows numerous other distinctive points. 


33. CARNEADES TESTULA, new species. 


Ground color creamy gray, powdered with black. Collar with a faint, 
smoky, transverse line. Thoracic vestiture long flattened hair, patagia 
and tuftings only fairly evident. Primaries with all the markings 
powdery, obscured. Basal line geminate, broken, blackish, not well 
marked, Transverse anterior line geminate, rather diffusely marked 
on the costa, thence slender, the two parts equally evident, almost

upright, outwardly bent in the interspaces. Transverse posterior line 
geminate, blackish, evenly outcurved over the cell, a little incurved 
below, inner line best marked and lunulate, outer more diffuse and more 
faint, but also lunulate. Subterminal line irregular, broken, pale, 
marked on the costa by a preceding dusky shade, leaving the apex 
clear, and below this by blackish preceding or following powderings. 
A series of small, dusky, terminal lunules, followed by a yellowish line 
at the base of the fringes. <A faintly marked, diffuse, dusky median 
shade darkens the space between the ordinary spots and crosses thence 
obliquely and evenly inward to the margin. Claviform small, the out- 
line traceable by a few black scales only. Orbicular round or nearly 
so, concolorous, outlined by black scales. Keniform large, broad, kidney- 
shaped, concolorous, narrowly outlined by black scales. Secondaries 
dull grayish white, with a rather broad smoky outer border, the fringes 
whitish with a yellowish line at base; veins and a discal lunule smoky. 
Beneath gray, powdery, primaries darker, both wings with a discal spot. 

Expanse, 36 mm.= 1.44 inches. 

Habitat.—Calgary, Canada (Dod). 

A single male, in good condition. This is an obscure powdery form 
allied to laggane, but with whitish secondaries and better-marked 
antennal joints. A distinctive character is the doubly lunate trans- 
verse posterior line, which is not shared with any of its allies. 


34. CARNEADES DIFFORMIS, new species. 


Ground color dull gray or smoky, powdery. Collar with a smoky 
median line. Thoracic vestiture hairy with some flattened hair inter- 
mixed, loose, patagia and tuftings well indicated. Primaries with the 
markings all coarsely written though not always distinct. Basal line 
geminate, black, slender, very close to base. Transverse anterior line 
outwardly oblique, outcurved between the veins and broken on them, 
geminate, inner part narrow, brown, rather even, outer black, broad, 
seeming rather a series of heavy black or brown curved marks than a 
line. Transverse posterior line geminate, evenly outcurved over cell 
and drawn in below, the outer line even, brown, the inner composed of 
thick black or smoky lunules separated by the gray veins. Subtermi- 
nal line irregularly sinuate, gray, narrow, marked by a broad, irregular, 
smoky preceding shade, which may or may not be cut with gray on 
the veins, the terminal space more or less dusky powdered. A series 
of black or brown terminal lunules, fringes luteofuscous. An upright 
or slightly curved median shade crosses the wing between the ordinary 
spots and may darken the outer portion of median space. Claviform 
Small, barely indicated or fairly evident. Orbicular moderate or rather 
small, round or nearly so, gray filled, outlined by black scales. Reniform

smoky with a yellowish tinge in the female, veins and a discal lunule 
darker. In the male there is an evident exterior dusky line, more or 
less broken, beyond which the wing is somewhat smoky to the smoky 
terininal line. Fringes white in both sexes and in the male unusually 
long. Beneath whitish gray, rather even, with a distinct discal spot 
and «a broad, blackish outer line nearly complete on all wings. 

Expanse, 30 to 33 mm.= 1.20 to 1.32 inches. 

Habitat.—Oregon (Schaus). 

Two males and one female, all different. The female is best marked 
and the main points in the description are from that specimen. One of 
the males is similar but much more obscure, all the black being changed 
to smoky brown, and in neither of these is the median shade anything 
more than a vague suggestion. The second male is intermediate in dis- 
tinctness of maculation save that the shadings to the subterminal line 
are obscured by a universal dusky shading, and here the median shade 
is present without doubt and darkens the space between the ordinary 
spots. These latter are large also in this last specimen, and I was at 
first strongly inclined to reject it as a member of this species. It agrees, 
however, in all other features, and particularly in the outer line of the 
secondaries above, which is not usual, and in the broad outer line of 
the under side. 

The antennal processes in the male are unusually long, so that the 
brush-like structure is prominent. 


35- CARNEADES DAKOTA, new species. 


Ground color a sordid clay yellow, powdered with smoky. Head and 
thorax concolorous. Vestiture hairy, but coarse and somewhat flat- 
tened; the tuftings not obvious in the specimens. Primaries without 
contrasts, the ordinary maculation written in blackish. Basal line 
unusually distinct, geminate, the two portions well separated. Trans- 
verse anterior line upright or a little oblique outwardly, marked by gemi- 
nate black spots on the costa, beiow which the inner line is lost, and 
the outer is made up of three interspaceal lunules preceded by a some- 
what paler shade. Transverse posterior line geminate on the costa, the 
outer line becoming lost in the outcurve over cell, inner line slender, 
crenulate, very oblique inwardly below the cell and a little incurved. 
Subterminal line vaguely marked by a slightly darker subterminal 
shade. <A series of smoky, interspaceal terminal lunules. Median 
shade broad, diffuse, smoky, almost upright, and crossing just inside the 
reniform. Claviform absent. Orbicular absent or marked by a dusky 
central dot. Reniform marked by a blackish or smoky kidney-shaped 
spot. Secondaries dirty-gray at base, smoky fuscous outwardly, fringes 
nearly white. Beneath whitish, powdery, both wings with outer lines 
and discal lunules. 

Expanse, 32 to 34 mm.—1.28 to 1.35 inches. 

Habitat.—Dakota: No definite locality.

form the species suggests audentis, which is a bright-colored form. 
The dusky reniform and obsolete or punctiform orbicular, combined 
with the other characters noted, should make this an easily recogniz- 
- able form, though sordidly obscure in appearance.

36. CARNEADES HOLOBERBA, new species. 


Ground color dull smoky brown with a purplish shade. Head con- 
eolorous. Collar with a distinct black median transverse line sur- 
mounted by purplish gray. Vestiture of thorax mixed scales and flat- 
tened hair, patagia slightly relieved, anterior divided crest and posterior 
tufting distinct. Primaries with all the markings distinct, the lines 
black or blackish, but not contrasting against the dark ground, the 
included spaces a little paler and serving to relieve the defining por- 
tions. Basal line geminate, evenly outcurved, distinct throughout. 
Transverse anterior line upright or a little oblique outwardly, somewhat 
irregular, the inner line hardly darker than the ground, outer black. 
‘Transverse posterior line sharply bent on the costal vein, then parallel 
with the outer margin. Outer line even, hardly darker; inner black, 
Junulate, the points much more extended on the veins. Subterminal 
line distinct, paler, more or less broken, forming a feeble W on veins 3 
and 4, marked by the slightly darker terminal space and a distinct, 
blackish brown preceding shade, which tends to break up into sagittate 
spots. A series of small, black, terminal lunules. Fringes concolorous. 
Median shade vaguely marked in one specimen. Claviform small, more 
or less completely detined by black scales, lightened .by a few paler 
scales. Orbicular round or a little oval, small or moderate in. size, 
paler in color and with a few darker, central scales. Reniform moderate, 
kidney-shaped, upright, incomplete above and below, black-margined 
within, outwardly with brown scales, a narrow, incomplete pale annu- 
lus relieving the spot from the slightly darker cell. Secondaries dull, 
smoky brown, fringes a little paler. Beneath smoky, powdery, with an 
outer line and discal spot, nuch better marked on the secondaries. 

Expanse, 38 mm. = 1.52 inches. 

Habitat.—Calgary, Canada, July 4 and 6 (Dod). 

Two female specimens in good condition. The species resembles 
brunneigera, but is much darker brown, with a purplish tinge, and the 
lines are obviously geminate and even in general appearance. 


a7. CARNEADES KERRVILLEI, new species. 


Ground color very pale, creamy gray, powdery. Head with a trans- 
verse blackish line across the middle, palpi blackish at sides. Collar 
yellow tipped, else blueish powdered. Thoracic vestiture mixed scales 
and hair, tuftings indefinite, yellow tipped, patagia gray powdered, 
somewhat relieved. A tutt of long white hair at base of abdomen. 


444 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL, XXII. 


Primaries with all the lines smoky, not ‘contrasting. Basal line appar- 
ently single, interrupted, very close to base. Transverse anterior line 
upright or even a little inwardly oblique, inner line best marked, a little 
outcurved in the submedian interspace, outer line powdery, diffuse, 
leaving a rather wide included space. Transverse posterior line single, 
blackish, very even, only a little outecurved over the cell and rigidly 
oblique below it. Beyond this line the wing is a little darker pow- 
dered. Median line smoky, fairly defined, almost midway between the 
median lines and, as nearly as possible, parallel to them in course. 
Subterminal line blackish, broken into irregular spots, of which the 
largest is on the costa, in course only a little uneven. Terminal dusky 
lunules very small. Claviform wanting. Orbicular large, round, not 
defined, marked by a gray central powdering. Reniform of good size, 
kidney-shaped, somewhat faintly outlined by dusky scales, gray-filled 
inferiorly. Secondaries white, with a small discal lunule, and a nar- 
row, smoky, powdery outer border. Fringes white. Beneath white, 
powdery, primaries a little darker, with a discal spot and a vague 
subterminal line; secondaries with a small diseal Iunule only. 

Expanse, 36 mm.= 1.44 inches. 

Habitat.—Kerrville, Texas (Dr. Barnes). 

A single male, in good condition. The species is allied to lineifrons 
and the series related to it, but is not to be confused with either. The 
transverse lines divide the wing into five spaces which narrow regu- 
larly from the base outward, and all the lines are essentially parallel 
to each other. The ordinary spots are so obscured that they require 
a second look to be recognized, and this, with the peculiar mottling of 
creamy yellow and bluish gray scales, is distinctive. The anterior 
tarsi—all that remain—are annulate with black and the antenne have 
the serrations not very much marked. 


38. CARNEADES TERNARIUS, new species. 


Ground color smoky fuscous, obscure, varying to red brown. Head 
with a brown or blackish frontal line. Collar with a feebly marked, 
dusky, transverse line. Thoracic vestiture mostly flattened hair with 
finer hair intermixed, patagia feebly marked, tufts obscure. Prima- 
ries with all the markings obscure, the blackish diffuse median shade 
being the most obvious feature. Basal line geminate, blackish, broken. 
Transverse anterior line geminate, upright, a little outcurved in the 
interspaces, blackish, broken, inner portion tending to become obsolete 
or entirely so. ‘Transverse posterior line geminate, evenly outeurved 
over the cell, a little incurved below, outer portion even, sometimes 
obsolete, inner slender, crenulate, blackish. Median shade, broad, 
blackish, diffuse, crossing the middle of the wing and only a little 
curved outwardly. Subterminal line irregular, marked by a blackish 
subterminal shade which varies in distinctness, and is in one ease alto- 
gether absent, the line itself being also lost in consequence. A black-

ish terminal line, tending to become lunulate, followed by a yellow line 
at base of fringes. The ordinary spots are practically obsolete, though 
the reniform may be traced by a vaguely paler shading and an equally 
vague, darker lunate mark. Secondaries smoky, a little paler at base, 
veins and a discal lunule smoky. Beneath gray to smoky, powdery, 
with or without a discal spot and outer line. 

Expanse, 33 to 37 mm.=1.32 to 1.48 inches. 

Habitat.— Denver, Colorado, October 9; Salida, July 10 (Oslar); Fort 
Collins, Colorado (Gillette); Colorado (Bruce). 

Four specimens, all females and no two alike. It is indeed with 
some hesitation that I have associated them all under one name, but 
all agree in the practical absence of the ordinary spots, the dominant 
median shade, and the generally sordid, obscure coloring. The differ- 
ence lies in the range between a distinct blackish shade defining the 
subterminal line, and its entire absence, the former being the type of 
the species. The shading of the secondaries in one specimen is dis- 
tinctly darker. It will require a series containing males to settle the 
matter fully. 

Type.—Cat. No. 4808, U.S.N.M. 


39. CARNEADES NOCTUIFORMIS, new species. 


Ground color a pale mouse gray, powdered with brown and blackish 
scales. Head with a broad brown transverse line. Collar inferiorly 
brown, surmounted by a black middle line, upper portion of the ground 
color. Thoracic vestiture mixed scales and flattened hair, patagia 
a little relieved, tuftings evident though not prominent. Basal line 
geminate, brown, outwardly margined by a brown shading in the sub- 
median interspace. Transverse anterior line geminate, lines almost 
equally well defined, inwardly bent from costa to median vein and 
touching the orbicular, outcurved in the submedian interspace and with 
a long outcurve below vein 1 so that the margin is reached very close to 
its middle. Transverse posterior iine not very well defined, geminate on 
the costa, but beyond that not well marked, even, outcurved over the 
cell, very close to the reniform and a little drawn in below. Subterminal 
line pale, irregular, not well marked, defined by a darkening of the ter- 
minal space which leaves the apex free, and by a dusky preceding shade 
which is best marked on the costa. A narrow, black, terminal line, fol- 
lowed by a yellow line at the base of the fringes. Median shade darkens 
the cell between the ordinary spots, then runs parallel with and rather 
close to the transverse posterior line, the space between becoming 
brown shaded and darker than the rest of the wing. Claviform evident, 
brown ringed, concolorous, moderate in size. Orbicular large, irregu- 
larly oval, oblique, open to the costa, outlined by black scales, annulate 
by a slightly paler ring, the center concolorous. Reniform large, broad, 
kidney-shaped, extending well below the median vein, black ringed, 
annulate by paler scales, center brown, with a yellowish median line. 


446 PROCEEDINGS OF THE NATIONAL MUSE uM. VOL. XXII. 


The wilt as a whole 1S dusky around. the ordinary spots. Secondaries 
smoky, with a yellowish tinge, darker outwardly, discal lunule pres- 
ent, fringes whitish. Beneath gray, powdery, discal lunule and outer 
line indicated on primaries only. 

Expanse, 35 to 36 mm. = 1.40 to 1.44 inches. 

Habitat.—Siskiyou, California, September 11 (Henry Eelwende)s east 
Washington (Piper). 

Two males. The type was received from Mr. Edwards several years 
ago and is in fair condition; the second example, from Washington, is 
rubbed and imperfect. It is darker throughout, the reniform has the 
inner margin drawn in so as to constrict it centrally and give it a flask 
shape, and the median shade line is not weli marked. Otherwise I see 
no essential differences, and the examples agree in somewhat unusually 
long antenne and in the shape of the primaries, which recalls Noctua 
rather than the more typical Carneades. 


40. CARNEADES INTRUSA, new species. 


In Bulletin No. 38, U.S. National Museum,' I called attention to what 
I then considered a variety of tessellata, and for which the term intrusa 
was suggested. With the material now at hand I have no hesitation 
in declaring the form entitled to specific rank. It resembles tessellata 
in general scheme of ornamentation, but the transverse anterior line 
is more upright, and the transverse posterior more evenly oblique below 
the middle of the cell. It is irregularly white powdered, and in each 
specimen the powdering is more prominent in a different space. In 
one it brightens the subterminal space, in another the costal region, in 
a third the basal space, and in the fourth the lower half of the median 
space. The powderings are coarse and not very close. The ordinary 
spots are more or less filled with these coarse white scales, and the reni- 
form is outwardly shaded with yellow. 

Expanse, 30 to 33 mm. = 1.20 to 1.33 inches. 

Habitat.—Sierra Nevada, California. 

Specimens labeled as above are in the U.S. National Museum collec- 
tion, the Edwards collection, and the Rutgers College collection.

41. CARNEADES NEOTELIS, new species. 


Ground color red-brown, more or less shaded with ash-gray. Head 
with a black or brown line across the middle of the front. Antenne 
with a discolored red, yellow, or gray tuft at base. Collar with a deep- 
brown median line, gray margined above, tending to become diffuse 
inferiorly; the base of the primaries usually marked by a discolored 
yellow or gray tuft. Thoracic vestiture mixed scales and flattened hair, 
EEE evident, tuftings distinct and pone to become discolored.

No. 1203. NEW NOCTUID MOTHS—SMITH. ALT 


Primaries very uniform in general tint, no strong contrasts, markings 
all present, but tending to become broken. Basal line geminate, black, 
with yellow included scales, broken in the cell. Transverse anterior line 
geminate, brown ov black, outwardly oblique and outcurved in the inter- 
spaces; outer portion distinct, inner portion much less marked, included 
space gray. Transverse posterior line geminate, blackish or brown, 
evenly curved over cell and a little drawn in below; outer portion even, 
tending to become lost, inner more or less evidently lunulate and not 
prominent. Subterminal line yellowish, irregular, broken, sometimes 
consisting of scattered yellow scales only, usually marked by preceding 
darker or blackish spots tending to unite, and by a preceding shade on 
eosta. The terminal space, save at apex, is a trifle darker. <A black 
terminal line, tending to become lunulate, is followed by a narrow yel- 
Jow line at the base of the fringes. A feebly marked median shade is 
evident in most specimens, outwardly oblique between the ordinary 
spots and a little irregular, but close to aud parallel with transverse 
posterior line below that point. Cell between the ordinary spots a little 
darker. Orbicular large, gray, oval, oblique, outlined by black scales. 
Reniform large, broad, upright, kidney-shaped, extending below the 
cell, outlined by black and annulate by pale scales, invaded by a yel- 
low shade at the middle of the outer margin, else a trifle darker 
than the ground, a leaden shade becoming marked inferiorly. Clavi- 
form small or moderate, incompletely outlined, never prominent. Sec- 
ondaries, smoky white in the male; darker, with a yellow shade in 
the female; darkening outwardly, veins and a narrow diseal lunule also 
darker. [Fringe whitish, with a yellow line at base and a smoky inter- 
line. Beneath, ranging from dirty white to smoky gray, powdery, 
discal spot and outer dusky line more or less obvious or complete on 
all wings. ; 

Expanse, 36 mm. = 1.44 inches. 

Habitat—Pullman, Washington, July (Piper); Colorado (Bruce). 

Two males and two females, remarkably similar in size and not much 
different in other respects. There is a little variation in the shade of 
brown and a little in the shade of the ornamental lines, but otherwise 
nothing. The species is perhaps near to insulsa, but lacks the strong 
contrasts and prominent claviform. It has the reniform of tessellata 
and becomes confusing by the presence of a fairly obvious median 
shade, combining thus the characters of two series.

42. CARNEADES ATROFUSCA, new species. 


Ground color mouse gray, varying to brown, always even. Ilead

not always present. Primaries with the median lines obscured and no 
strong contrasts. Basal line geminate, sometimes marked on the costa 
only, but often complete and relieved by yellow, included scales. Trans- 
verse anterior line geminate, usually traceable by black or smoky scales - 
across the wing; in course a little outwardly oblique, and slightly out- 
curved in the interspaces. Transverse posterior line geminate, trace- 
able with difficulty in some examples, obsolete in others. Subterminal 
line pale, irregular, always broken, usually only scattered yellow scales, 
which are often altogether absent. Sometimes the yellow scales are 
emphasized by preceding black atoms, and in one case the line is marked 
by a somewhat deeper preceding shade. Terminal line narrow, black, 
relieving a yellow line at the base of the fringes. Claviform small, 
traceable in all the specimens, not complete in any. Orbicular large, 
oval, irregular, oblique, concolorous, more or less completely outlined 
by black seales, within which, in some specimens, yellow scales tend to 
bring it into relief. KReniform large, kidney shaped, extending below 
the cell, more or less imperfectly outlined by black scales, and usually 
better defined by an inner ring of yellow or whitish scales, which may 
invade the spot centrally. Usually the center is concolorous, but it 
may be slightly darker. Secondaries dirty yellowish white, outwardly . 
smoky, the female more yellowish, with a broader soiled margin, discal 
lunule evident, fringes white, with a yellow line at base and a smoky 
line beyond this. Beneath gray, powdery, with the usual tendency to 
an outer line and a discal spot on all wings. 

Expanse, 32 to 35 mm. = 1.28 to 1.40 inches. 

Habitat.—Glenwood Springs, Colorado, August, September, October 
(Barnes); Colorado (Bruce); Pullman, Washington, July (Piper). 

Six males and four females are at hand. They vary from a mouse 
gray to a red brown in ground color, and from almost immaculate to a 
type in which all the markings can be traced by darker or paler scales. 
The best-marked ‘specimen resembles a normal tessellata without the 
black, and in fact this species resembles the common form when all its 
characteristic markings have been washed out. It is perhaps even 
closer to satis, which is larger, better marked, has a black line across 
the collar, and a broken, black, longitudinal line at base.

43. CARNEADES OBJURGATA, new species. 


Ground color red brown, more or less overlaid by violet scales, less 
marked in the male, which tends to rusty shadings. Head violet in the 
female, often rusty in the male, palpi dusky at the sides. Collar with 
a brown or blackish median line, which is margined above by violet 
scales, inferiorly a little paler or even rusty yellow, in which case there 
is a patch of rusty scales at the base of the primaries. Primaries with 
all the markings present, the surface powdery and mottled with black,

gray, brown, and yellow scales. Basal line geminate, black, both por- 
tions equally distinct, usually pale filled, outwardly angulated on the 
median vein, beneath which a line of black séales may connect this 
angulation with the transverse anterior line. Transverse anterior line 
geminate, diffuse on the costa, outer part broad, black; inner narrower 
and blackish; included line always paler and sometimes yellowish; in 
course outwardly oblique, with outcurves in the interspaces. Trans- 
verse posterior line geminate, inner blackish, lunulate rather than 
crenulate, the outer smoky, even; its course is a rectangular bend over 
the cell, and then parallel with the outer margin or a little incurved to 
the inner margin. Subterminal line always evident, pale, sometimes 
punctiform, usually marked by the darker terminal space, and some- 
times by a preceding broken or continuous shade as well, forming a 
small W on veins 3 and 4 when best marked. Median shade quite dis- 
tinct, oblique between the ordinary spots, then rather close to and 
parallel with the transverse posterior line to the margin. Claviform 
moderate or small, concolorous, often incomplete, but always at least 
partly outlined in black. Orbicular moderate or large, oblique, oval or 
irregular, more or less completely black ringed, annulate with violet or 
yellowish, the center paler than the ground, so that the spot is relieved 
without being really contrasting. Orbicular large, kidney-shaped, 
extending well below the median vein, laterally outlined by black 
scales, incomplete above and below. An annulus of yellow or violet 
scales lies within the black margin, and these scales encroach from the 
concave outer border and sometimes nearly divide the spot. The center 
is of the ground color, but darkens inferiorly, and it may be relieved 
by a pale central lunule. There is a series of black terminal lunules, 
and a pale line at the base of the fringes. Secondaries soiled whitish, 
with a smoky outer margin, broader and darker in the female, the 
yellowish tinge very faint, yet perceptible. Beneath gray, powdery, 
with the usual outer line and discal spots all more or less evident. 
Thoracic vestiture an admixture of scales and flattened hair, patagize 
relieved, tuftings well marked. 

Expanse, 32 to 386 mm.= 1.28 to 1.44 inches. 

Habitat.—Pullman, Washington, July and August (Piper); Dakota. 

Size and general habitus of tesseilata without the black filling, and 
much mottled and powdered; more like friabilis, but smaller and some- 
what shorter winged, not so evenly gray. The male seems to resemble 
tessellata most nearly in habitus, whereas the female tends rather to — 
messoria in the better-defined median shade. Ten specimens, equally 
divided as to sex, are under examination.

base of the primary joins the thorax marked be yellow scales. The 
anterior divided crest and posterior tufting evident. Primaries a little 
powdery, markings all present, but diffuse and not clearly written. 
Basal line geminate, black, inner complete, bent on the median vein and 
running in on the submedian so as almost to reach the base. Transverse 
anterior line geminate, outer portion black, distinct, inner smoky, 
scarcely evident, both portions broken in the costal space. Asa whole 
the line is a little oblique outwardly, and is outcurved in the interspaces. 
Transverse posterior line geminate, inner part black and lunulate, outer 
smoky and even. As a whole the line is well removed outwardly, 
leaving a wide median space; is very slightly outcurved over the cell 
and is almost evenly oblique or a very little incurved below. Subter- 
minal line pale, irregular, marked chiefly by a preceding dusky shade 
in the subterminal space, and by the slightly darker terminal space 
below the apex. There is also a somewhat dusky, indefined, preceding 
shade, which may be broken into irregular blotches; but is never 
contrasting. Terminal line narrow, black, broken, the base of the 
fringes a little yellowish. Median shade quite well defined, smoky, 
darkening the cell somewhat between the ordinary spots, and running 
parallel to and well removed from transverse posterior line below the 
reniform. Claviform concolorous, moderate in size, narrow, incompletely 
black margined. Orbicular of good size, oblique, irregular, oblong 
rather than oval, black ringed except on costal vein, a white inner 
annulus relieving the concolorous center. Reniform large, kidney- 
shaped, extending below the median vein, outlined by black scales 
except above and below, better defined by a whitish annulus, which is 
somewhat emphasized by yellowish scales exteriorly; center dusky, 
with a powdering of yellow scales toward the middle. Secondaries 
pale, smoky yellowish, more whitish toward the base, fringes white 
tipped, yellowish at base, smoky interlined, cell closed by a smoky 
lunule. Beneath whitish, with black powderings, a more or less evident 
common outer line and a discal lunule.

the base of the fringes. Claviform wanting. Orbicular large, oblique, 
incomplete above, annulate with pale, else concolorous. Reniform 
large, kidney-shaped, extending well below the cell and seemingly 
much too large for uhe insect; not outlined except by the black filling 
of the cell and the blackish filling of the spot which defines it against’ 
the ground color. Secondaries white, veins yellowish, marginal line 
smoky. Beneath, primaries gray, secondaries white, both powdery

Two males from the U. 8S. National Museum, in not the best of con- 
dition. The species is-allied to obeliscoides in type of maculation, but 
has no contrasts and does have a well marked subterminal line pre- 
ceded by sagittate black marks. From the protean forms of perexcel- 
lens I believe it to be safely distinguished by the form of the ordinary 
spots and their uniformity with the ground color.

47. CARNEADES HENRIETTA, new species. 


Ground color red brown, more or less evidently overlaid by gray 
scales. Head variable, but usually of the color of the inferior portion 
of collar. Collar with a distinct, black, median transverse line, above 
which is the ground color of the wing and below which the color is 
usually contrasting gray, yellow, or brown; but it may be concolorous 
with the ground. Primaries may be entirely uniform in color or the 
costal region may be contrastingly yellowish or rusty luteous to the 
transverse posterior line. All the lines incomplete and sometimes 
barely traceable. Basal line usually marked by geminate dusky spots 
on the costa, and by black spots in the submedian interspace; a black 
longitudinal mark extending from this point to the transverse anterior 
line. Transverse anterior line geminate, outwardly oblique and well 
outcurved in the interspaces, so that it reaches the inner margin not 
much within its middle, interrupted in the costal region. The inner 
part of line is scarcely defined, the outer is black, included space 
usually a little paler. Transverse posterior line geminate on the costa, 
thence single, fine, crenulated, rarely complete, sometimes marked only 
by the contrast between subterminal and median spaces, sometimes 
scarcely more than indicated. Subterminal line pale, slender, more or 
less broken, a little toothed on veins 4 and 5, sometimes marked by 
the darker terminal space, sometimes by a few preceding scales, and 
sometimes not at all. A series of interspaceal terminal points, send. 
ing brown rays across the terminal space which, when darker, leaves 
the apex pale. Subterminal space usually a little paler and sometimes 
obviously contrasting. Veins dusky. Median cell more or less black 
powdered before and between the ordinary spots. Claviform variable in 
size, outlined in black, sending from its tip a narrow black line through 
the submedian interspace and above this a paler ray to the transverse 
posterior line. Orbicular oval, moderate or large, incomplete above, 
else black ringed, inwardly relieved by a pale annulus, the center con- 
colorous or paler. Reniform large, kidney-shaped, oblique, black 
ringed, annulate with yellowish, the center a mixture of yellowish and 
blackish scales in varying proportions. Secondaries whitish, with a

faint yellowish tinge in the male, more @ smoky in the female, with a 
dusky outer line, from which a very narrow shade may or may not 
extend irregularly inward. Discal lunule faintly marked. Beneath 
gray, powdery, secondaries more whitish, all wings with an incomplete 
outer line and a discal spot. 

Expanse, 30 to 34 mm.=1.20 to 1.36 inches. 

Habitat.— Alameda County, California, September (U.S.N.M.); Santa 
Cruz Mountains (Ehrhorn); Senator, Arizona, June 25 (Dr. Barnes). 

Five males and two females, no two alike. This species has approxi- 
- mately the same range of variation as perexcellens Grote=infeliv Smith, 
but it is decidedly smaller, the wings are broader, more stumpy, there 
are no sagittate spots preceding the subterminal line in the contrast- 
ing individuals, and, altogether, the species differs so conse in habi- 
tus that there seems little danger of confusion. 

Type.—Cat. No. 4806, U.S.N.M. 

[Larva.—Head bilobed, broad, clypeus broadly triangular, rather 
high, the paraclypeal pieces nearly attaining the vertex; pale brown, 
speckled with darker over the sides and at the top of each lobe; labrum 
pale, jaws dark at tip, ocelli in a brown patch; width, 3.5mm. Body 
somewhat flattened, robust, feet normal, but all small and short; 
tubercle iv of joints 9 and 10 at the upper corner of the spiracle. Thin 
skinned, translucent whitish, the dorsum faintly shaded with reddish. 
Cervical shield distinct, brown, with brown impressed strigz, cut by 
three white bands; anal plate obscure, brown dotted. Spiracles black. 
Tubercles moderately large, brown, obscure. No marks in the blown 
example.

48. CARNEADES VANIDICUS, new species. 


Ground color luteous with a slight reddish tinge, in the female so 
heavily shaded with gray as to seem smoky or ashen. Head of the 
palest ground color, the tip of the frontal vestiture sometimes a little 
darker. Collar with arather narrow black median transverse line, below 
- which it is paler and, usually, contrastingly discolored. Thoracic vesti- 
ture mixed scales and flattened hair, patagia relieved, dorsal crest and 
tuftings distinct, and in the male a little discolored. Primaries with the 
costal region pale, discolored, gray (female) to yellow (male), a pale streak 
through the submedian interspace and another from the middle of the 
reniform outward and curved upward to the apex. Basal line marked 
only by the pale included space below the median vein, where it breaks 
the longitudinal black shading, which extends to the transverse anterior 
line. Transverse anterior line geminate, marked by smoky spots on the 
costa and by an obliquely outward curve in the submedian interspace. 
Transverse posterior line practically obsolete in most cases or only 
marked opposite the cell by the somewhat darker median space, in one 
female traceable for its full course, and there a little incurved. Veins

more or less marked by dusky scales, the median alls accompanied by a 
series of pale scales. Subterminal line pale, defined by the uniformly . 
dusky terminal space and by a series of variably evident sagittate black 
spots or dashes. A series of brown or blackish lunules, beyond which 
the fringes are pale, with a narrow, dusky, interline. Olaviform dis- 
tinct, pointed, usually reaching the center of the wing in the femaie, a 
little shorter in the male, and sending off a slender black line from its 
tip through the submedian interspace. Orbicular oblique, oval or 
oblong, moderate in size, usually incomplete above, defined by a narrow 
black ring, within which is a paler annulus, the center of the ground 
color or paler. Reniform large, kidney-shaped, scarcely extending 
below the median vein, black ringed, annulate with pale, with a dusky 
center, which may be encroached upon by pale scales; there is a tend- 
ency to a little backward spur along the median vein from the lower 
margin of the spot. Cell, except for the ordinary spots, filled with 
smoky or black. Secondaries whitish in the male, with a narrow, 
smoky, outer border; smoky gray and almost uniform in the female; 
fringes white in both cases. Beneath whitish, powdery, disk of pri- 
maries smoky and with a distinct discal spot and incomplete outer line. 
Secondaries paler, with a small discal spot only. 

Expanse, 31 to 35 mm. = 1.24 to 1.40 inches. 

Habitat.—Pheenix, Arizona, November 4 to 11 (Griffith); Pullman, 
Washington, September 27 (Piper). 

Seven specimens, of which half are male and half are female, one 
example being the most complete possible example of a union of both 
sexes. The left side from the median line of the body 1s. completely 
male, the right side is as completely female. Ovipositor and claspers 
are both present and the differences in antennal structure is marked. 
The two pairs of wings afford a perfect illustration of the sexual color 
differences and make it certain that the two are correctly associated. 

So far as the material indicates, the variation is mostly sexual, the 
male being in all respects the brighter, with greater contrasts and a 
predominating yellow shade. The female is more uniformly gray, and 
the contrasts are not nearly so great, the costal region seeming whitish 
rather than yellow. 

The species is allied to perexcellens; but is smaller, with differently 
shaped ordinary spots and much whiter secondaries. From henrietta 
it is distinguished by more pointed primaries, much stronger color con- 
trasts, the sagittate spots before the subterminal line, and the form of 
the ordinary spots.

49. CARNEADES FCEMINALIS, new species. 


Ground color ashen gray, shaded with smoky or blackish. Head 
gray inferiorly, vertex smoky brown. Collar with a broad, black median 
band which is tipped with gray and below which there is a reddish

tinge. Thoracic vestiture mostly flattened hair, patagia marked and 
edged with gray scales, tuftings obvious. Primaries with costal region 
contrastingly gray or whitish, this shade invading the orbicular and, 
to some degree, the reniform as well as, occasionally, the inner margin. 
Basal line marked by a smoky costal spot only. Transverse anterior 
line geminate, marked on the costa, obsolete through the cell, then very 
obliquely outcurved in the interspaces; outer portion blackish, evident, 
inner smoky, obscure, defined chiefly by the somewhat paler included 
space. A black or blackish shade defines the pale costal space from 
the base to the transverse anterior line and this shade continues so as 
to fill the cell around the ordinary spots and the median space above 
vein 2. Transverse posterior line geminate on the costa, thence single, 
very slightly crenulate, broadly curved over the cell, well incurved 
below. Subterminal line gray or whitish, irregular, broken, terminal 
space clarker except at apex, preceded by a dusky subterminal shade, 
which is best marked on the costa and tends to break up into somewhat 
triangular spots. There is a faint, terminal, blackish line. Claviform 
moderate, black ringed, sometimes concolorous, sometimes gray, and 
Sometimes the margins almost join to make it solidly black. Orbicular 
narrow, oblique, oblong rather than oval, varying in size, gray-filled. 
Reniform moderate in size, kidney-shaped, not extending below the 
median vein, black margined, then annulate with white, the center con- 
colorous and variably gray powdered. Secondaries white with a smoky 
tinge in the male, darker and with a more yellowish shade in the female; 
fringes white, veins and a discal lunule dusky. 

Expanse, 31 to 37 mm.—1.24 to 1.48 inches. 

Habitat.—Garfield County, Colorado, 6,000 feet (Bruce). 

Two males and two females; one of the latter apparently a little 
dwarfed and crippled, which accounts for the range of size variation; 
the other examples are 35, 36, and 37 mm., respectively. The species is 
allied to furtivus or idahoensis, but has none of the red or brown shad- 
ing, and the transverse posterior line is complete. Aside from this the 
form of the ordinary spots differs, and this new species has the markings 
much more obvious and is less even in appearance. 

Type.—Cat. No. 4784, U.S.N.M. 


50. CARNEADES NORDICA, new species. 


Ground color smoky brown, with a more or less obvious red shading, 
the female with a gray shading over all. Head with a dusky frontal 
line across the middle. Collar with a distinct black median line, which 
is tipped with gray; in the male a reddish or rusty shade predominates 
below this line and leaves a rusty patch at the base of the primaries; 
in the female a gray shade replaces the red. Thoracic vestiture mixed, 
patagia defined, tuftings distinct and a little gray tipped. Primaries 
with the costal region gray to the transverse posterior line, this shade 
invading the orbicular and to some extent the subterminal space. The

cell is black filled around the ordinary spots, and a blackish shading 
is in the basal space below the median vein, shading to the ground 
color inferiorly, sharply limited above. Basal line marked by geminate — 
black spots on the costa, and by a gray line interrupting the black below 
the median vein. Transverse anterior line geminate, interrupted by 
the pale costal shade, outwardly oblique and outeurved in the inter- 
spaces below that point. Transverse posterior line geminate, the inner 
line crenulate, outer even and not so well marked; as a whole, evenly 
curved over the cell and a little drawn in below. Subterminal line 
pale, irregular, a little dentate on veins 3 and 4, defined by the dusky 
terminal space which leaves the apex of the ground color, and a dusky 
preceding shade which is best marked on the costa and is more or less 
broken into undefined spots elsewhere in its course. A broken blackish 
terminal line, followed by a yellow line at the base of the fringes. 
Claviform black ringed, variable in size, though never very large; a 
fine black line from its tip through the submedian interspace and a 
slightly paler shading above it. Orbicular oblique, oval or oblong, 
open to the costa superiorly in the female, incompletely closed in the 
male. Reniform upright, kidney-shaped, of good size, hardly extending 
below the cell, defined by a gray annulus and the center more or less 
gray powdered. The median vein is gray to the reniform, and a powder- 
ing of gray scales is variably evident along the inner margin. Sec- 
ondaries smoky, more yellowish at the base, darker in the female, 
fringes whitish. Beneath, primaries smoky, secondaries gray, pow- 
dery; all with an incomplete outer line and a discal lunule, the latter 
usually obsolete on the primaries and sometimes so on the secondaries. 

Expanse, 35 to 38 mm.=1.40 to 1.52 inches. 

Habitat.—Calgary, Canada, July 16, 19, August 3 (Dod); Olds, 
British Columbia (Fletcher). 

Two males and two females. Is an ally of divergens and has the pale 
median vein; but the ordinary spots are not outlined in pale and are 
_ different in shape, opening on the pallid costa. This is also a much 
grayer species and the contrast are more sharply marked. It has a 
little the appearance of furtivus, but the powdery markings and com- 
plete median lines easily distinguish it. 

Type.—Cat. No. 4786, U.S.N.M. 


51. CARNEADES FACTORIS, new species. 


Ground color fawn gray, more or less brown shaded. Collar with a 
transverse black median band which is diffuse inferiorly, and tends to 
darken the lower portion centrally. Thoracic vestiture mixed scales 
and flattened hair, patagia fairly defined, tuftings obscure. Primaries 
with all the markings somewhat broken, median space a little darker 
red brown, costa a little more shaded with gray, cell yet darker or 
blackish before and between the ordinary spots. Basal line geminate, 
marked by black spots on the costa and by the paler included shade

which cuts the black or brown basal shade. This black or brown shade 
extends below the median vein from base to transverse anterior line 
_ and is diffuse inferiorly. Transverse anterior line geminate, outer por- 
tion black, lost in the costal region; inner brown, not much contrasting, 
included space gray; in course it makes an inward bend from costa to 
median vein, then outcurved to vein 1, below which it has another, 
longer, outcurve. Transverse posterior line geminate, outer lire even, 
hardly darker, tending to become lost, the inner lunulate, black or 
brown, included space a little brighter red, as a whole quite evenly » 
outcurved over the cell and a little drawn in below. Subterminal line 
narrow, yellowish, more or less broken, only a little irregular in course, 
defined by the paler apical space and marked by small, irregular and 
somewhat diffuse brown spots. Terminal line very narrow, brown, 
followed by a yellow line at the base of the fringes. Claviform rather 
short and broad, black ringed, usually a little incomplete, tending to 
become brown filled. Median vein gray marked. Orbicular irregular, 
oblong, oblique, open superiorly, but not merged into the costal shade; 
narrowly annulate in pale gray, as a whole lighter than ground. Ren- 
iform moderate, rather narrow, irregularly kidney-shaped, scarcely 
extending below the cell, defined by black scales within which is an 
imperfect ring of pale scales; evenly filled with lighter gray. Second- 
aries an even, smoky yellowish, veins and discal lunule darker, fringes 
pale, with a yellow line at base. Beneath, ranging from whitish to 
smoky gray, powdery, with or without discal spots and outer lines on _ 
all wings; no two specimens being alike. 

Eixpanse, 33 to 40 mm. = 1.52 to 1.60 inches. 

Habitat.—Glenwood Springs, Colorado, June, July, and August (Dr. 
Barnes). p 

Five females in fair condition only. The range of variation is chiefly 
in size and in the amount of contrast between the ground color and the 
dark shadings in the median space and cell. 

The species is allied to divergens but is more even in color, with less 
contrast on the median vein and pale rings surrounding the ordinary 
spots, and with quite different transverse anterior line and orbicular.

52. CARNEADES CAZESIUS, new species. 


Ground color reddish brown, washed with blue gray. Head rich red- 
brown, verging tocarmine. Collar blue gray, with a carmine transverse 
line above the middle. Thorax very robust, mixed thin and flattened 
hair, patagia well marked and brown, tuftings prominent, blue gray. 
Primaries nrostly blue gray. The inferior half of basal space, the clavi- 
form, and the filling of the ordinary spots is brown. The terminal 
Space save apex and the subterminal shading are smoky. Basal line 
indicated only below the cell, where it cuts the black shade which 
extends to transverse anterior line, but is not prominent. Trans-

verse anterior line marked as a gray line through the submedian 
interspace only. ‘Transverse posterior line marked on the costa and 
traceable over the cell by the contrasts between the brown and gray, 
lost below that point. Subterminal line distinct, gray, marked by a 
preceding smoky costal shade, and thereatter by the smoky terminal 
space and a preceding, continuous, smoky shade. A narrow, lunulate, 
black terminal line, followed by a yellow line at base of fringes. Clavi- 
form very large and broad, reaching to the middle of the wing. 
Orbicular round, of good size, broadly ringed with blue gray. Reniform 
large, broad, kidney-shaped, broadly ringed with gray. The median 
vein is prominently gray. Before the orbicular is a triangular black 
spot, and the space between the ordinary spots is black. Secondaries 
dirty yellowish at base, becoming smoky outwardly, veins and a discal 
lunule smoky. Fringes yellow at base, smoky at middle, white at tips, 
dise with a discal spot and a subterminal dusky line. Secondaries with 
a dusky Junule and a dusky costal and outer border. 

Expanse, 34 mm.= 1.36 inches. 

Habitat.—Middle California (Dr. Barnes). 

A single female of this bright little species. The body is unusually 
robust and the wings are in consequence actually and proportionally 
small or ‘‘stumpy.” It should be associated with redimicula, where it 
will be easily separated froin the described species. 


53. CARNEADES ACUTIFRONS, new species. 


Ground color dark red brown, shaded with black and pale gray. 
Head brown with a black transverse line, the frontal protuberance 
being more acute than usual in the genus. Collar with a black central 
line, below which it is very pale gray, tinted with yellowish, and above 
which it may be reddish or of the ground color. Thoracic vestiture 
with long flattened hair and scales intermixed, tuftings distinct and a 
little reddish anteriorly, patagia defined, disk blackish, margin indi- 
cated by reddish scales, Primaries well marked with strong contrasts; 
costal region gray or whitish to the transverse posterior line, apex paler, 
cell, except for the pale ordinary spots, black filled. Basal line gemi- 
nate, black, narked on the costa and again in the submedian interspace 
where the whitish included shade cuts the biack shade which extends 
to the transverse anterior line. Transverse anterior line geminate, 
black, broken, inner line not well marked, included space pale, out- 
wardly oblique, and outcurved in theinterspaces. Transverse posterior 
line geminate on the costa, inner line slender, black, a little lunulate, 
tending to become lost, squarely exserted over the reniform, very oblique 
and a little incurved below. Subterminal line slender, whitish out- 
wardly, dentate on veins 3 and 4, preceded by a dusky shading, partly 
broken into black dots or spots, and by a broader costal shading. 
Terminal space save apex darker. A slender black terminal line, fol- 
lowed by a pale line at the base of the fringes. Claviform prominent,

filled. Orbicular ovate, irregular, oblique, small, outlined in black 
filled with whitish or gray scales which may be brown centered. Reni- 
form large, kidney-shaped, extending well below the cell, more or less 
discolored by white, gray, or yellow scales. As a whole the lower half 
of the wing is the lighter and it may be quite contrastingly gray. The 
subterminal space is on the whole a little lighter than either median or 
terminal spaces. Secondaries pale, soiled yellowish at base, darker, 
smoky, outwardly, veins and a narrow discal lunule also smoky. 
Beneath smoky, powdery, with common discal spot and outer band. 

Expanse, 33 mm.=1.32 inches. 

Habitat.—California; Oregon. 

One male and one female for which I have no more definitive locality 
than above given. The specimens are old, but in good condition. 

The species stands by ttself by the unusually narrow primaries and 
very oblique outer margin. Though of almost average expanse it seems 
like a very small species and indeed is the smallest of those with con- 
trasting costa, discolored spots, and basal black markings. 

Type.—Cat. No. 4794, U.S.N.M. 


54- CARNEADES SELENIS, new species. 


Ashen gray over a somewhat luteous base. Head and collar infe-

above which itis gray. Thoracic vestiture mixed scales and hair, tuft- 
ings evident, patagia marked and with a narrow, black submargin. 
Primaries with the median lines not relieved, barely traceable; terminal 
space and a prominent shade preceding subterminal line smoky, black- 
ish. Basal line geminate, barely traceable to the slender, black, basal 
line which is with difficulty traceable to the transverse anterior line. 
The latter is geminate, outwardly oblique and outeurved in the inter- 
spaces. ‘Transverse posterior line evident on costa and through the 
abrupt outward bend over the cell; below that point it is just trace- 
able as being parallel with the outer margin. Subterminal line very 
distinct, broad, yellowish, preceded by a blackish, smoky shade, which 
tends to break up into triangular spots. <A series of small terminal 
lunules, beyond which there is a narrow pale line at base of fringes; a 
median dusky line, being narrowly cut with white. Median shade 
vaguely diffuse below the reniform. Claviform long, slender, a little 
paler, outlined in blackish scales which do not form a continuous line. 
Cell smoky before and between the ordinary spots. Orbicular small, 
oval, ringed with black scales, annulate with pale, center of the ground 
color. Reniform small, kidney shaped. Center and interior portion 
filled with blackish, elsewhere narrow black margined and with a yel- 
lowish annulus. Secondaries white, with a rather broad, smoky margin. 
Beneath whitish, powdery, primaries with a discal spot and the outer 
margin somewhat dusky, secondaries powdery along the costa only.

A single female, from the collection in the U.S. National Museum. 
It is an ally of stilens, but much smaller, with small ordinary spots and 


very sharply marked subterminal line. It recalls atrifera in size and 


habitus, but is quite distinct. 
55. CARNEADES LAMINIS, new species. 


Ground color dull fuscous, primaries washed with ashen gray. Head 
brown. Collar with a rusty shade at base, reaching the insertion of 
the wings, margined above with a broad, black central line. Thoracic 
vestiture mostly flattened hairs, patagia and tuftings obvious. Pri- 
maries gray along the costal region halfway across subterminal space, 
the cell smoky, darker than any other part of the wing. A thread-like 
black line extends from base to the transverse anterior line, shaded a 
little with smoky. Basal line geminate, blackish, broken in the cell. 
Transverse anterior line geminate, smoky, obscure, outwardly oblique, 
outeurved in the interspaces, lost in the cell, and feebly marked below 
internal vein. Transverse posterior line geminate on the costa, single 
below the cell, fine, crenulate, sinuate, not relieved. Subterminal line 
gray, irregular, dentate on veins 3 and 4, defined by the dark terminal 
space except at apex, which is clear, and by a preceding shade which 
fills the subterminal space on costa and is broken and more or less 
punctiform below the middle of the cell. A series of small black ter- 
minal lunules, followed by a yellow line at base of fringes. No median 
line. Olaviform barely indicated. Orbicular small, irregular, oblique, 
gray, centered with smoky, partly outlined by black seales. Reniform 
moderate, kidney-shaped, gray, powdered with smoky, inwardly 
defined by black scales, outwardly by the dusky space beyond it; 
above and below not defined. Secondaries dirty yellowish white, with 
a smoky outer border; veins and a narrow discal lunule, smoky. 
Fringes yellow at base, with a brown central line, white at tip. 

Expanse, 3£ mm. = 1.36 inches. 

Habitat.—Middle California (Dr. Barnes). 

A single male in good condition. The species resembles a small 
tesselloides, but is not nearly so well defined and has a dull smoky 
brown tinge not found in the older species. The ordinary spots are 
also different and the collar in tesselloides is bright ashen gray infe- 
riorly, notrusty. Altogether this is a darker species and more sordid. 


56. ANYTUS ATRISTRIGATUS, new species. 


Ground color gray with a variable smoky tinge. Head with smoky 
frontal and interantennal lines. Collar black tipped. A blackish 
band from the eyes to the base of the primaries. Patagia margined

to the outer margin through the submedian interspace, the line set in 
a blackish shading, which extends on each side and is diffuse at the 
edges. Basal line blackish, geminate, toothed on the veins. Trans- 
verse anterior line geminate, black, the two parts equally distinct, 
widely separated on costa, gradually becoming approximate toward 
inner margin. In course it is irregular, the long inner tooth on sub- 
median vein being best marked. Transverse posterior line unusually 
near outer margin, leaving a very wide median space, geminate, outer 
line best defined, narrow, black, inner smoky, included space white, 
irregularly angulate and dentate, squarely exserted over the reniform, 
drawn in below, a prominent outward tooth in the submedian inter- 
space. Subterminal line whitish, irregular, incomplete. A series of 
black terminal spots, forming the tips of sagittate blackish marks 
which cut the fringes. A blackish irregular bar fills the subterminal 
Space opposite the cell. Median shade black on the costa, oblique 
through the reniform, becoming smoky, then irregular and close to the 
transverse posterior line. No obvious claviform. Orbicular round or 
oval, then annulate with whitish, center concolorous. Reniform large, 
broad, irregularly kidney-shaped, larger superiorly, ringed with black, 
filed with smoky or blackish. Secondaries almost white, with a 
smoky, punctiform, exterior line and a series of smoky terminal lunules. 
Beneath white, powdery, both wings with a more or less complete, 
. Sinuate, outer line and good-sized discal spot. 

Eixpanse, 37 to 41 mm. =1.48 to 1.64 inches. 

Habitat.—Texas. 

Two males and one female, the latter greasy and a little defective. 
The species is altogether different from the other described species, 
‘and the black-shaded streak through the submedian interspace of 
primaries will distinguish it at a glance.

vague, curved, diffuse, median shade. Subterminal line dull yellow, 
distinct, continuous, a little irregular, preceded by black blotches in 
the interspaces; that opposite hind angle being largest and most 
obvious. Terminal space mottled with yellow scales. Fringes long,

black, more or less completely yellow filled and contrasting. Second- 
aries smoky or blackish brown, paler, more yellowish at base, darkest 
in the female, fringes yellowish, with a brown interline. 

Expanse, 31 to 33 mm. = 1.24 to 1.32 inches. 

Habitat.—Senator, Arizona, April 24 (female), July 16 (male) (Dr. 
Barnes). 

One pair in only fair condition, the male the larger and best marked, 
the female so dark and powdery that the contrasts in the male are the 
more striking. The antennz in the male have the joints well marked 
and laterally tufted. The species thus belongs in division A,! of the 
genus, and its broad primaries ally it to detracta; but the apices in the 
new form are well marked, the outer margin is more oblique, and the 
wing as a whole is more triangular, resembling rather obscwra and 
quadrata. 

The under side is smoky, powdery, with a continuous, black, extra- 
median line, fringes yellowish, a yellowish discal lunule on primaries 
and a blaclish spot on secondaries. 


58. MAMESTRA RAINIERII, new species. 


Re 


Ground color ash gray with a smoky tinge, head and collar concolor- — 


ous. Thorax with black tipped scales darkening the disc, patagia 
with a black submargin. Primaries with all the maculation broken; 
the upper portion of basal space and the large ordinary spots are 
whitish gray, and contrast enough to form the most prominent orna- 
mental features. Basal line black, geminate, upright. Transverse 
anterior line geminate, outer part black, inner smoky, included space 
whitish gray, broken, outwardly oblique, with small outcurves in the 
interspaces. Subterminal line geminate, the defining lines obscure, 
the included whitish space only being traceable across the wing, 
abruptly bent over the cell and a little incurved below; median space 
as a whole a little the darkest portion of the wing. Subterminal line 
made up of white scales, emphasized by a series of black spots in the 
interspaces, in course only a little irregular. A dusky median shade 
is marked on the costa. Claviform large, black ringed, powdered with 
white. Orbicular large, oval, incompletely black ringed, white 
powdered. Reniform very large, broad, kidney-shaped, outlined in 
black, white powdered. Secondaries uniformly dull smoky, very 
powdery. Beneath, uniformly smoky, roughly powdered, secondaries 
with a prominent black discal spot. 
Expanse, 35 mm.=1.40 inches. 
Habitat.—Mount Rainier, Washington (C. V. Piper).

This species, represented by a single, somewhat rubbed male, offers a 
number of characters that make its removal from Mamestra probable 
when better examples of both sexes are available. <As it stands now 
it belongs next to gnata, because the antenna has the joints distinct 
and laterally with small tufts. The head is retracted though broad, 
front very flat, palpi small. Thorax quadrate, vestiture loose, diverg- 
ent. Collar and patagie well marked, but dorsal tuftings obscure. 
Primaries abruptly widened at transverse anterior line, thence nearly 
parallel to the rounded hind angle, outer margin very oblique, making 
a long drawn out though rounded apex. The fringes are wanting in 
the specimen. This wing form is not paralleled elsewhere in the genus; 
but I have been unable to find any better place for it and prefer not to 
make a generic type of a defective specimen. 


59. MAMESTRA BOLTERI, new species. 


Ground color a dull, reddish luteous, shaded with smoky. Head yel- 
low, with a smoky interantennal shade. Collar yellow at tip. Tho- 
racic tuftings yellow tipped, disk of patagia smoky. Primaries with- 
out contrasts, the median lines diffuse, smoky and broken, the sub- 
terminal line pale and forming the most obvious feature in the macula- 
tion. Basal line smoky, marked chiefly by the ineluded space, which 
is of the ground color and breaks the dusky shading in the upper half 
of the basal space. Transverse anterior line smoky, geminate, broken, 
diffuse, a little oblique outwardly and irregular in the interspaces. 
Transverse posterior line geminate, smoky, diffuse, broken, included 
space of the ground color, rather abruptly bent below the subcostal 
over cell and incurved below that point. Subterminal line pale, dis- 
tinct, relieved and made prominent by continuous dusky shadings on 
each side, only a little irregular in course. A series of small, black, 
terminal lunules. Fringes long, yellowish at base, with a diffuse, dusky 
interline, reddish at tip. Median shade diffuse, darkening the space 
between the ordinary spots, then rather close to and parallel with the 
transverse posterior line. Claviform very small, vaguely outlined, 
relieved by a few yellow scales. Orbicular small, round, a little paler 
than ground color, and so defined by the contrast with the surround- 
ing shade. Reniform moderate, upright, only a little constricted, outer 
and upper portion a little yellowish, inner and lower portion smoky. 
Secondaries uniformly smoky, with a yellowish, somewhat glistening 
shade, fringes long, yellow at base, more whitish at tip, with an inter- 
mediate smoky line. Beneath, primaries smoky, a little paler along 
costa, where an extra-median line is indicated, and on the fringes. 
Secondaries more reddish, powdery, with a small discal lunule and a 
somewhat diffuse, extra median line. 

Expanse, 37 mm. = 1.48 inches. 

Habitat.—Las Vegas, New Mexico (A. Bolter). 

A single female, in excellent condition as to wings, but thorax com-

pressed and vestiture disarranged. This species is unlike any of the 
species heretofore described and is without close allies. It belongs to 
the vindemialis series on superficial characters, but has a closer resem- 
blance to Agrotid forms like Noctua pyrophiloides, the normal mark- 
ings of the messoria group of Carneades being combined with the dif- 
fuse shadings of the first-mentioned form. 


60. MAMESTRA YAKIMA, new species. 


Ground color ashen gray, powdery. Head darker, with a more or 
less obvious dusky interantennal line. Collar with a series of darker 
scales forming a vague median line. Patagia with a blackish submar- 
gin. Primaries with all the markings obscured, tending to but not 
really strigate, paler rays on veins 3, 4, 6, and 7 cutting into the darker 
terminal space. Claviform vaguely marked and extending to the mid- 
dle of the wing. Orbicular round or oval, small or moderate, concolor- 
ous, marked by a slightly paler ring. Reniform large, broad, kidney- 
shaped, but larger inferiorly and there filled with leaden gray which 
makes it fairly obvious. A series of small black terminal lunules. 
Secondaries white, with a blackish outer border, which shades into the 
white well before the middle, veins blackish, fringes white. Beneath 
white, a little powdery toward the margins, primaries with a dusky 
discal lunule. 

Expanse, 30 to 36 mm. —1.20 to 1.44 inches. 

Habitat.—Yakima, Washington (C. V. Piper). 

One male and two females, in only fair condition. On very close 
examination the maculation seems to be of the trifolit type, though so 
nearly obsolete that this is difficult to recognize; at all events the den- 
tations of the subterminal line refer it to that series. The male antennz 
are ciliate and the species is peculiar in having a little pointed frontal 
protuberance, so small as to be easily overlooked, yet actually existent. 
This, so far as I am aware, is unique in the genus. 

Type.—Cat. No. 4836, U.S.N.M. 


61. MAMESTRA DILATATA, new species. 


Ground cclor white, overlaid by smoky, luteous, olivaceous, and black 
scales, so as to leave the white base visible only in the lines, ordinary 
spots, and basal space of primaries. Head yellow, with a gray interan- 
tennal tuft. Collar white, tipped with smoky, with a broad, black 
median line. Patagia white, margined with black, the disk mottled 
with white, black, and olivaceous scales. Primaries with basal space 
superiorly white, inferiorly gray. Basal line geminate, black, marked 
on the costa, the inner portion normal, the outer dislocated and form- 
ing an oblique blackish mark in the submedian interspace, separating 
the white and the gray shading. Transverse anterior line geminate, 
black, included space white, oblique to the submedian interspace, 
inwardly angulate on vein 1,outcurved below. Transverse posterior

line geminate, black, narrowly lunulate, included space white, its course 

irregular, outward bend over cell large, so that the line is well removed 
outwardly and the median space is wide. Subterminal line white, 
broken, irregular, marked by preceding black spots and following 
_ Shades, obscured by the white mottling in the subterminal space 
and the gray apical region. Median shade indicated on the costa, lost 
in the dark space below until it reappears in the gray shade which 
extends along the entire inner margin. Fringes whitish, with a series 
of black lunules at base, and a series of olivaceous lunules at tip. 
Claviform small, black margined, white centered. Orbicular small, 
round, black ringed, white centered. Reniform moderate, upright, 
dilated superiorly, a little constricted in the center, lower half much 
narrower, black margined, white filled, with a central olivaceous shade. 
Secondaries smoky brown, a little paler at base, fringes white, a smoky 
interline extending from the apex half way to the anal angle. Beneath 
smoky, primaries powdery along the costa, fringes white, marked as on 
the upper side: secondaries whitish basally, a broad extra median 
shade line limiting the smoky outer margin; costa powdery, a discal 
spot smoky. 

Expanse, 30 mm. = 1.20 inches. 

Habitat.—New Mexico. 

One female from the collection of the United States National Museum. - 
This is one of the mottled species not easily describable, resembling 
variolata in general appearance and referable to the adjuncta group. 
It differs in the much darker shadings, in the form and course of the 
lines, and, most obviously, in the form of the reniform. In fact, on close 
comparison the resemblances to other species turn out to be casual 
only. 

Type.—Cat. No. 4827, U.S.N.M. 


62. MAMESTRA FLORIDA, new species. 


Ground color white, powdered with dull luteous and black scales, 
which gives a very pale gray cast. Head and thorax without mark- 
ings. Primaries with the maculation rather well written, the large 
blackish reniform being the most prominent feature, a black costal sub- 
terminal blotch, a smaller blotch on the subterminal line opposite the 
cell, and the dark claviform being the other distinctive features. Basal 
line geminate, black, included space white, distinct, broken on the 
median space. Transverse anterior line geminate, black, outwardly 
angulated in the submedian interspace, and outcurved below vein 1. 
_ Transverse posterior line geminate, outer portion even, smoky, inner 
narrow, linear, denticulate, black, as a whole nearly parallel with the 
outer margin. Subterminal line white, marked by a preceding dusky 
Shade, irregularly sinuate. A series of blackish terminal lunules. 
Median shade oblique from costa to reniform, which is completely 
darkened by it, then vague, diffuse, smoky, parallel with aud close to

a 


transverse posterior line. Claviform a small black loop at the angle of 
the transverse anterior line. Orbicular very small, blackish ringed, 
white centered, round. Reniform a large black blotch without definite 
outline. Secondaries white; veins, a punctiform median line, a sub- 
marginal indefined band and a narrow terminal line blackish. Beneath 
white; primaries with a black discal blotch fading out gradually in 
all directions, and a blackish venular line. Secondaries with a frag- 
mentary dusky submarginal line. 

Expanse, 32 mm.=1.28 inches. 

Habitat.—Biscayne Bay, Florida (Mrs. Slosson). 

A single male specimen, in good condition. The species is obviously | 
related to chartaria, and has the same general type of maculation; but 
it is much paler, smaller in size, and has white instead of smoky sec- 
ondaries. There are a number of other minor differences in the macu- 
lation, which put the distinctness of this species beyond reasonable 
question. The genitalia have not been examined. 

Type.—Cat. No. 4837, U.S.N.M. 


63. MAMESTRA ROSEOSUFFUSA, new species. 


Ground color dull whitish, mottled with smoky gray, which in turn 
is washed with a rosy or pink tinge or shading. Head and collar 
creamy, palpi brown at the sides. Thorax with a pink tinge over the 
creamy ground. Abdomen smoky luteous. Primaries with the dark, 
smoky overlay predominating to the outer portion of median space, 
then evenly defined against the whitish ground that prevails to 
the subterminal line, broken only by three dusky clouds in the sub- 
terminal space. Terminal space dusky, except at apex. Basal line 
geminate, outeurved in the interspaces, included space broad, whitish. 
Transverse anterior line geminate, outwardly oblique, irregularly out- 
curved in the interspaces, hardly defined, included space broad, whitish 
mottled. Transverse posterior line narrow, brown, crenulate, single, 
best marked on the veins. Subterminal line whitish marked by the 
dusky terminal space, and by three dusky preceding clouds. A series 
of terminal smoky dots on the veins, fringes with a series of triangular 
pale spots at base, from which pale lines extend to the tip. Orbicular 
small, round, very obscure, with a whitish annulus. Reniform not 
defined, forming a little darker shading. Claviform vaguely marked. 
A smoky median shade lies just within the dark area of the wing and 
practically bounds it. Secondaries yellowish, smoky. Beneath very 
pale, with a yellowish tinge. Primaries with a partial outer line and 
a smoky subterminal line. Secondaries whitish, creamy and powdery 
along the costa, with a small discal spot and half a row of extra median 
spots. 

Expanse, 28 mm. = 1.12 inches. 

Habitat.—Arizona. 

A single good male, which has been in my collection for some years, 


No. 1203. NEW NOCTUID MOTHS—SMITH. 467 


It has the wing form of and belongs with renigera and its allies. The 
peculiar rosy shading and the evenly marked contrast between the light 
and dark shading in the outer portion of median space should distinguish 
this species. 

64. MAMESTRA GRISEATA, new species. 


Ground color dark, powdery, ash-gray, without marked contrasts. 
Head with a smoky interantennal tuft. Collar with a blackish median 
line. Patagia blackish margined at base of wings. Primaries witha 
smoky, upright shading through the median space, and a similar shade 
in outer portion of subterminal and terminal space, leaving the apex 
free. Basal line geminate, blackish, broken. A small, black, basal 
streak terminates at the end of this line and the part of the basal space 
so inclosed is white-powdered. Transverse anterior line well removed 
from base, consisting only of a gray scale line without darker defining 
portions ; in course slightly and evenly outeurved. Transverse pos- 
terior line geminate, smoky, included space gray, somewhat acutely 
outeurved over the cell and distinetly incurved below. Subterminal 
line white, slender, irregular, somewhat broader and prominent oppo- 
site the anal angle, relieved by the dark shading on both sides of it. 
A narrow black lne at base of fringes which are gray, cut with 
smoky. Claviform rather short and broad, pointed, black margined, 
concolorous. Orbicular oval, oblique, moderate in size, outlined by 
black seales, then annulate with whitish gray, the center concolorous. 
Reniform outlined and ringed in the same way, rather small, upright, 
a little drawn in from the outside, but scarcely kidney-shaped. Sec- 
ondaries smoky, paler at base, fringes whitish. Beneath paler gray, 
powdery; primaries with an outer band marked in the costal region 
only; secondaries with extra median smoky band complete, and a dark 
discal spot. 

Expanse,-23 to 30 nm.=0.92 to 1.20 inches. 

Habitat.—Hall Valley, Colorado (Dr. Barnes). 

One male (the larger) and one female, in fair condition. This species 
has the antennal joints of the male very distinctly produced, laterally, 
and furnished with bristle tufts so as to be entitled to the term brush- 
like. It is therefore allied to gnata and should come near to it in the 
arrangement. In wing-form it is like vicina. 

The most remarkable thing in the specimens before me is the dispro- 
portionately small size of the female, which is perhaps not the rule. 
The ovipositor, it may be noted, is exserted in the specimen under exami- 
nation. It may be that, with further material at hand, Ulolonche will 
prove a better genus for the species; but it may require an examina- 
tion of the male genitalia to determine the matter finally.

base, overlaid with bright red brown. Basal line single, angulate, black. 
Transverse anterior line nearly upright, single, black, with a triangular 
spot on costa and inner margin, else narrow, irregular. Basal space 
mottled, yellow and brown. ‘Transverse posterior line black, broken, 
followed by a yellow shade line, outcurved over the reniform. Median 
space mainly brown, lighter below the submedian, with a smoky blotch 
on the inner margin. Subterminal line yellow, narrow, with irregular 
outeurves and inward teeth. Subterminal space brown, the yellow 
more obvious toward inner margin along transverse posterior line. 
Terminal space brown, some of the veins marked with yellow. A series 
of small, black, terminal lunules, beyond which is a series of yellow 
spots at the base of the fringes. Ciaviform not traceable in the 
specimen. Orbicular small, white, punctiform. Reniform creamy, with 
a brown central line, moderate in size, lunate in form. Secondaries 
whitish at base, darkening to smoky outwardly, the veins smoky, 
fringe more yellowish. Beneath whitish, reddish powdered along the 
costal region. Extra median dusky line and discal dots on both wings, 
and on primaries the terminal space is paler. f 

Expanse, 25 mm.=1 inch. 

Habitat.—Cocoanut Grove, Florida (KE. A. Schwarz). 

A single good male from the U. 8S. National Museum. This is a 
small, narrow, and blunt winged form like egens Walker, or more 
like the small species of Mamestra. The bright, deep rusty brown, 
which is the predominating shade, is altogether different from any 
other described species known to me. The tarsi are brown, narrowly 
ringed with yellow. 

Type.—Cat. No. 4822, U.S.N.M. 


66. HADENA LUTEOCINEREA, new species 


Color a mottling of luteous and cinereous. Front and collar whitish, 
patagia with black submargin, thoracic disk luteous, posterior tufts 
gray; abdominal tufts blackish, abdomen pale luteous. Primaries 
shaded with white along the costal vein and a little powdered in the 
costal region. Basal line barely indicated on the costa. Transverse 
anterior line marked by an oblique smoky shade on the costa, and 
beyond that only by the difference between the yellowish base and 
smoky median space; its course a rather small, even outeurve. Trans- 
verse posterior line geminate on the costa, then outcurved over the cell 
and deeply incurved below, greatly narrowing the median space in the 
submedian interspace; defined only by the contrast between smoky 
median and yellowish subterminal space. Subterminal line yellow, 
irregularly angulate and sinuate, defined by the dark terminal space 
and a preceding gray shade which fills the subterminal space at costa 
and in the middle, leaving two yellowish blotches. A series of small, 
black terminal lunules. A small black line or streak at base. Orbic-

ular oblique, white. Reniform upright, kidney-shaped, moderate in 
size, marked by black scales, inwardly annulate with white. Clavi- 
form broad, pointed at the tip, extending across the median space, 
black lined, concolorous. Secondaries whitish, with a narrow smoky 
margin and a discal lunule. Beneath whitish, powdery, primaries 
smoky along costal region, secondaries with a discal lunule. 

Expanse, 33 mm.=1.32 inches. 

Habitat.—Montana. 

A single male in fair condition. The species is related to characta 
in wing form and general pattern of maculation, but differs in the yel- 
low shadings and generally paler colorings. 


67. HADENA MUSTELINA, new species. 


Ground color bluish gray, with brown shadings. Head and collar 
chocolate brown, patagia edged with brown scales posteriorly. Abdom- 
inal vestiture defective. Primaries with the ornamentation obvious 
along the costal region only. Basal line geminate, inner line deep 
brown, outer faint. Transverse anterior line geminate, inner line faint, 
brown, outer black on the costa, then dislocated, broken, and marked 
only by a few black scales across the wing; as a whole the line is a lit- 
tle outeurved, and outwardly oblique. Transverse posterior line gemi- 
nate, marked by black spots on the costa, then brownish, obscurely 
lunulate, widely outcurved and, as a whole, nearly parallel with the 
outer margin. Subterminal line pale, irregular, preceded by scattered 
black scales and by a brown costal shade. Terminal space, except 
apex, a little darker. A brown, crenulated, terminal line. Ordinary 
spots proportionately very large, concolorous. Orbicular oblique, oval, 
open above, preceded by a black patch on the median vein, which 
seems continuous with the black inception of the transverse anterior 
line. Reniform kidney-shaped, defined by slightly darker scales, 
except that the narrow space between it and the orbicular is blackish 
brown. Claviform marked through the basal space by a whitish shade, 
margined above by black scales, and beyond the transverse anterior 
line by a margin of black, inferiorly edged by white scales, outline not 
complete inferiorly; in form it is short and broad. Secondaries smoky, 
even, fringes white, based by a darker line. Beneath, primaries smoky, 
with a scarlet tinge along costa and toward apex, an incomplete outer 
line and a discal lunule. Secondaries whitish, with a vinous red shade 
along costa and a blackish discal spot. 

Expanse, 29 mm.=1.16 inches. 

Habitat.—Santa Cruz Mountains, California. 

One male, evidently bred, numbered, in red, No.536, by Mr. A. Koebele. 
The specimen is evidently a little crippled, but the maculation is per- 
fect and only the vestiture ot the abdomen is defective. I cannot say, 
therefore, just how it is tufted. In a general way the species is allied 
to the modica series, but not closely to anyone in particular.

68. HADENA JOCASTA, new species. 


Ground color, dull fuscous gray. Head and thorax not maculate, 
patagia obscurely submargined with black. Vrimaries with the mark- 
ings well written, median lines connected by a prominent black bar 
through the submedian interspace; a white shade filling the subter- 
minal space beyond it tothe anal angle. Basal line geminate, blackish, 
marked on costa only. A short black basal streak, reaching less than 
half way across the basal space. Transverse anterior line geminate, 
outer portion of line black, inner obscure, intervening space a little 
whitish powdered, as a whole a little outeurved. Transverse posterior 
line single, slender, blackish, crenulate and outcurved over the cell, 
even and incurved below. Subterminal line paler, a little sinuate, pre- 


ceded by a darker shade; the terminal space also a little darker except 


at apex. A series of blackish terminal lunules, beyond which the 
fringes are cut with black. A median shade line is indicated between 
the ordinary spots and below the transverse bar. Claviform forms part 
of the bar connecting the median lines. Orbicular large, oblique, oval 
paler than ground, partly outlined by black scales. NReniform large, 
concolorous, kidney-shaped, the inner edge black margined, outer not

slender; outer line brown, indefinite, included space a little paler. 
Subterminal line pale, broken, a little irregular, preceded by black or 
brown marks in the interspaces. A series of small, black, terminal 
lunules. Orbicular round or oval, center concolorous, annulate with

almost oval, the sides a little flattened, large, incompletely outlined 
and with a paler annulus relieving the concolorous center. Claviform 
concolorous, outlined in black, extending halfway across median 
space, a black line from lower margin continuing to the transverse 
posterior line. There is a black streak along the inner margin near 
the base, and a black line from the lower part of reniform to the sub- 
terminal line. The tendency is to a darkening of the interspaces in 
terminal and subterminal spaces, taking the form of brown or blackish 
lines or spots. Secondaries whitish, with a narrow smoky margin in 
the male; smoky, paler at base, in the female. Beneath, varying from 
whitish to smoky, more or less powdery, with an incomplete outer line

Two males and two females; none of them first class. The species 
is not really referable to Hadena, having an untufted abdomen; but it 
resembles the mactata series in markings and the lewcoscelis series in 
wing form, hence I place it here tentatively.

One female in good condition. The species belongs to the series 
with aedon and pulverulenta, differing from each in the ground color 
and details of maculation. I am quite certain that I have seen this 
species in collections with a name to which it is not entitled. The 
species of this genus do not seem to be common and of some of them 
I have seen only the types. 


71. POLIA ACERA, new species. 


Ground color an even purplish gray with a reddish shading through 
the median space of primaries. Head with a brown frontal line. Col- 
lar more whitish inferiorly to a sharply defined black, transverse line. 
Patagia well marked, with a vague submarginal darker shading. 
Primaries with a sharply defined, slender, black streak from base 
through the submedian interspace, nearly to the transverse anterior 
line. Another less distinct black streak along inner margin, reaching 
somewhat nearer to the center of the wing. Basal line not traceable 
in the specimens before me. Transverse anterior line obsolete or very 
feebly traceable; geminate, with long outcurves in the submedian 
interspace and below the submedian vein. ‘Transverse posterior line 
almost obsolete or imperfectly marked, geminate over the cell, then 
the inner line narrow, black, dentate on the veins. Subterminal line 
wanting or indicated by brown interspaceal streaks which are best 
marked opposite the cell and above the anal angle. Fringes reddish 
gray. The veins are marked with black scales. There is a brown, 
median shade line which is incomplete, marked between the ordinary 
spots and from the tip of the claviform to the inner margin. Clavi- 
form black ringed, concolorous, extends halfway across the median 
space, a slender black or brown streak connecting it with the trans- 
verse posterior line. Orbicular oblong, oblique, nearly or quite reach- 
ing the reniform, and probably in soine instances confluent with it; a 
little paler than ground, incompletely outlined by black and brown 
scales. Reniform large, upright, kidney-shaped, somewhat irregular, 
open above and tending to enlarge, else narrowly outlined by brown 
seales, a little yellowish centrally. Secondaries smoky yellowish, paler 
at base, fringes whitish. Beneath, whitish or smoky, a little powdery, 
without obvious lines or spots. 

Expanse, 42 (male) to 52 (female) mm.=1.68 to 2.08 inches. 

Hebitat.—Pullman, Washington (C. V. Piper); Seattle, Washington. 


No. 1203. NEW NOCTUID MOTHS—SMITH. AG3 


One pair only, the male in good condition save that itlacks anten- 
ne; the female, which is much older, somewhat defective. The species 
has the wing form of theodori, but differs utterly in maculation from 
all others of the genus. 

Type.—Cat. No. 4826, U.S.N.M 


72. POLIA DISPAR, new species. 


Ground color very pale luteous gray, almost white. Collar with a 
faint, smoky line below the tip. Patagia with a submarginal, diftuse, 
black line. Primaries with smoky powderings which obscure the ordi- 
nary maculation. Basal line vaguely indicated by smoky marks on 
the costa. Transverse anterior line hardly more obvious, but by patch- 
ing together the scattered black scales, it is seen that the line is strongly 
angulate in the interspaces, the tooth below the submedian vein almost 
meeting one from the transverse posterior line. The tooth in the cell 
takes the form of a black, angulate mark before the orbicular. A 
short, slender, blackish streak from base to basal line in the cell and a 
similar, more obscure streak along the inner margin into the tooth of 
the transverse anterior line. Transverse posterior line somewhat better 
marked but obscure, incomplete, with long, irregular outward teeth on 
the veins, and long inward dentations in the interspaces; that in the 
submedian being best marked. Median shade smoky, somewhat dif- 
fuse, oblique from costa between the ordinary spots, then inwardly 
bent from the lower angle of reniform. It is a little the best marked 
feature of the wing. Subterminal line concolorous, marked by a series 
of preceding, sagittate, smoky marks. A series of distinct, black, 
interspaceal, terminal lunules, beyond which the fringes are cut with 
smoky. Fringes a little dentate. Orbicular small, round, concolorous, 
incompletely and very narrowly outlined by black scales. Reniform 
large, upright, a little kidney-shaped, obscurely annulate with yel- 
lowish, a little darkened by the median shade inferiorly. Secondaries 
in the male white, immaculate; in the female with smoky veins, a smoky 
terminal line and smoky powderings toward anal angle where an 
extra median dusky line is well indicated. Beneath white or nearly 
so with small discal spots, much less obvious in the male. 

Expanse, 42 (male) to 45 (female) mm. = 1.68 to 1.80 inches. 

Habitat.—Glenwood Springs, Colorado, October 1-10 (Dr. Barnes). 

One pair, both fairly good examples. The male has the antenne ser- 
rated and bristle tufted. The primaries are a little broader and more 
pointed than usual in the genus, and the species is much more obscurely 
marked. Yet, so far as the maculation is traceable, its dentate char- 
acter fits well into the series in which I have placed it. The very light 
color separates it from all save ochracea, and from that species, the 
white secondaries of the male and the totally different ordinary spots 
will distinguish it.

73. POLIA OCHRACEA, new species. 


Ground color a dirty pale gray, with smoky powderings and yel- 
low ocherous shadings. Collar, thoracic disk, and patagia with ocher- 
ous shading. Primaries with the ordinary lines all present, smoky, 
not prominent. Basal line geminate, smoky, broken, the included 
space broad and whitish on costa. Costal region and cell shaded 
with blackish before the transverse anterior line, which is unusually 
well removed from base. Transverse anterior line single, out- 
wardly oblique, smoky, outcurved below median and outwardly toothed 
below submedian vein. Transverse posterior line single, smoky, 
irregularly dentate or zigzag, well outcurved over the reniform and 
well bent inward below, so that the median space is much narrowed. 
The two lines are connected by a smoky bar in the submedian inter- 
space. Median shade smoky, diffuse, obscure, broken, the median 
space being so much powdered that the shade line is only locally defin- 
able. Subterminal line composed of ocher yellow, somewhat lunate 
marks preceded by smoky shadings. A narrow, blackish, interrupted 
terminal line. Fringes a little dentate. Orbicular large, broad, sides 
outlined in ocher yellow, open above and below. Reniform very large, 
broad, a little constricted centrally, more so from the outside, sides 
marked with ocher yellow scales, above and below indefined. Ocher 
yellow scales are scattered over the wing, but are more obvious in the 
basal and subterminal spaces. Secondaries whitish, with a smoky 
tinge, with a blackish extra-median line, a smoky, diffuse, subterminal 
shading, a blackish, lJunulate terminal line and a smoky discal lunule. 
Beneath with a yellowish tinge; primaries smoky on disk, both with 
an extra-median dusky band and a dusky lunule. 

Expanse, 43 nm. = 1.72 inches. 

Habitat.—lowa. 

A single, rather defective male, received years ago from Henry 
Edwards. The antenne are serrated aud bristle tufted. The species 
should be recognizable from its ocherous mottlings, which are different 
from any congeneric form, The wings are rather broad and pointed, 
as in dispar, which this species most resembles. 


74. PERIGEA LUCETTA, new species. 


Ground color glistening fawn brown, with a tendency to yellow 
shadings. Head yellow in front, with a narrow black line, a velvety 
brown interantennal line and a velvety brown neck. Palpi yellow in 
front, brown at the sides. Collar with a yellowish shade toward base, 
above margined by a black transverse line. Patagia marked, with a 
yellowish shade at costal base of primaries. Primaries with the ordi- 
nary lines obscure. Basal line marked by scattered yellow and black 
scales. Transverse anterior line with difficulty traceable, partly gem- 
inate, a little outeurved. Transverse posterior line a series of inter- 
spaceal blackish lunules; abruptly bent on the costa, else nearly parallel

with the outer margin. It is followed by a broad, vague yellowish 
shading, merging gradually into the ground. Subterminal line unusu- 
ally close to outer margin, irregular, consisting of silver gray scales 
placed in groups. A seriesof black interspaceal terminal spots, edged 
with gray scales and fringes cut with gray. Claviform indicated by 
smoky scales, very small. Orbicular small, broadly oblong, upright, 
edged by whitish or gray scales. Reniform moderate, outlined by a 
narrow gray line, with a figure-8 shape, a little paler centrally, almost 
whitish below. Space between the ordinary spots more blackish and a 
similar shade obtains beyond the reniform. Secondaries smoky, darker 
outwardly, glistening, the fringes whitish. Beneath, primaries smoky, 
reddish powdery along costa, whitish along internal margin, terminal 
space gray. An extra-median smoky line. Secondaries gray, reddish 
powdery along the costal region. An extra median brown line, which 
does not reach the inner margin. ‘Terminal space narrowly gray, mar- 
gined by a brown band, which almost fills the space to the extra median 
line on the costa, but narrows toward and barely reaches the internal 
angle. 

Expanse, 41 mm.=1.64 inches. 

Habitat.—Colorado (Barnes). 

A single, good male. This is a large form and quite different in 
appearance from our other species. It has somewhat the shading of 
fabrefacta, but is very differently marked. 


75. PERIGEA CERVINA, new species. 


Ground color a somewhat glistening, soft fawn brown with scattered 
black powderings, some of the scales tipped with white. Head and 
thorax without obvious markings. Primaries without contrasts, all 
lines obscured. Transverse anterior line marked by obscure blackish 
shadings, which indicate that it is upright, outwardly angulated in the 
interspaces. Transverse posterior line marked by a series of small, 
obscure, blackish venular dots, outcurved over the cell. Subterminal 
line composed of a series of irregular, interspaceal, blackish marks. A 
series of rather obvious white dots terminates the veins, and a very 
obscure series of dusky spots marks the interspaces. Orbicular irreg- 
ular, oval, concolorous, obscurely and incompletely outlined by blackish 
scales. Reniform large, broad, incompletely outlined by black scales, 
among which a few white ones are interspersed: concolorous except for 
an oblique whitish streak through the lower half. Claviform a small 
blackish spot below the orbicular in the submedian interspace. Sec- 
ondaries evenly smoky, a trifle paler at base, fringes more whitish. 
Beneath gray, powdery, reddish tinted outwardly and along the costal 
mergin, a dusky outer line and a discal mark on all wings. 

Expanse, 38 mm. = 1.52 inches. 

Habitat. Florida;” Mrs. Slosson. 

The species resembles vecors and albolabes in wing form and habitus,

and is somewhat like punctifera in color, but it is larger than the latter 
and much more obscurely marked. It may be described from a more 
southern locality, but I have failed to recognize it. {f have only one 
good female example. 


76. PERIGEA TEXANA, new species. 


Ground color dirty fuscous brown, more or less black powdered. 
Head and thorax without definite markings. Primaries with all the 
normal maculation present; no prominent contrasts. Basal line single, 
black, followed by a somewhat paler shading, outwardly angulate on 
the median vein. Transverse anterior line black, single, generally bro- 
ken, usually preceded by a paler shading, outwardly oblique, broadly 
toothed. Transverse poster.or line single, black, slender, continuous, 
followed by a paler shade, irregular in course, but almost upright and 
only alittle bent over the cell. Subterminal line pale, broken, preceded 
by a blackish shading which becomes developed into a large triangular 
patch opposite the cell and forms the most prominent feature of the 
wing. Terminal space usually a little darker, as is also the median 
space, leaving the subterminal space the palest portion of the wimg. 
A series of narrow, dusky terminal lunules, cut by whitish dots on the 
veins. A narrow, dusky median shade extends from costa obliquely 
to the lower margin of the reniform, then parallel with the transverse 
posterior line to the margin; usually only the part below the reniform 
is obvious, but in some examples it can be traced its full course. Orbic- 
war variable in size and form, from triangular to round, always of the 
lighter ground color, narrowly outiined in black. Reniform upright, 
always of good size, somewhat variable, usually wide, a little con- 
stricted centrally, lower portion larger than the upper, a few white 
scales marking the lower angles. The space between these ordinary | 
spots is often darker and sometimes partly black. Claviform a little 
black loop at the end of an outward angulation of the transverse ante- 
rior line. Secondaries smoky, with a yellowish tinge, much paler at the 
base, fringes yellowish. Beneath pale, powdery, with a discal dot and 
narrow extra median line black; all well marked in some examples but 
almost completely absent in others. 

Expanse, 27 to 30 mm. = 1.03 to 1.20 inches. 

Habitat—Round Mountain (Schaupp); Shovel Mountain, Texas 
(Barnes). 

Kight males and one female, mostly in good condition, There is little 
real variation, though no two examples are alike. The ordinary spots 
differ in size and a little in shape; but the species remains obviously the 
same. It belongs to the series with rather short wings and stout body, 
like loculosa Grote, and really resembles a reduced Luperina rather 
than normal Perigeda.

77. PERIGEA CONSORS, new species. 


Ground color a dull luteo-fuscous, more or less black powdered. 
Head and thorax immaculate. Primaries with cell before and between 
the ordinary spots more or less completely black filled. Basal line 
marked by black scales on the costa and vaguely traceable to the 
median vein. Transverse anterior line marked on the costa and by 
black scales which emphasize a difference in shade between basal and 
median space. In course it is a little oblique, strongly angulate or 
broadly toothed. Transverse posterior line narrow, blackish, irregular, 
followed by a paler shading. Subterminal line pale, preceded by a 
dusky shade which is broader opposite the cell. A broken dusky ter- 
minal line, veins pale tipped. A vague, narrow, median shade, 
marked on the costa and again below the reniform. Orbicular small 
in the specimens, irregular, tending to open to the costa. Reniform 
rather large, a little constricted centrally, larger below. Claviform 
small, outlined by blackish scales. Secondaries whitish, with a yellow 
tinge at base, with a broad smoky border and a sinall discal spot. 
Beneath pale, powdery, with a broken outer line and discal spots. 

-Expanse, 25 to 27 mm. = 1.00 to 1.08 inches. 

Habitat.—Pheenix, Arizona (Dr. Barnes). 

Two males and one female, all of them poor and at first sight resem- 
bling small, rubbed examples of P. texana. Vhey are, however, 
smaller throughout, and the black-filled cell is a conspicuous difference. 


78. CARADRINA LEUCORENA, new species. 


Ground color pale luteous, with a reddish tint. Head and thorax 
immaculate. Primaries with the reniform white marked, a dusky 
shading along median vein, sometimes to the base, giving a little the 
appearance of a Leucania. Transverse anterior line irregular, gemi- 
nate, broken, marked only by blackish scales, sometimes scarcely 
traceable. Transverse posterior line geminate, smoky, with the usual 
outcurve over the cell, thence rather evenly oblique, or only a little 
incurved. Outer line composed of small venular dots. Inner line may 
be continuous, slender, and crenulated, a series of interspaceal lunules, 
or a series of venular marks. Sometimes the line is scarcely traceable 
and it is never prominent. Subterminal line is an irregular, vague, 
paler shading, which may or may not be edged by darker scales. 
Fringes a little darker, sometimes obscurely cut with smoky, sometimes 
based by a series of small, blackish, interspaceal lunules, sometimes 
by white dots terminating the veins. Orbicular a round dot of the 
darker powdering, surrounded by a.ring of the even ground color; but 
it is always obscure and as often wanting. Reniform upright, narrow, 
centrally constricted, very obscure, except that the outer edge is partly 
white and the inferior portion is also white. Secondaries even, dull, 
pale smoky, with a yellowish tinge, lighter basally. Beneath paie,

creamy gray, with a reddish tinge, with or without an outer smoky line ~ 
and discal spot on one or both wings. 

Expanse, 28 to 38 mm.=1.12 to 1.52 inches. 

Habitat.—Los Angeles County, California, in September (U.S.N.M.); 
southern California (Barnes); Phoenix, Arizona, March 11 (Dr. Grif- 
fiths). 

Hight specimens, seven of them females, are before me, most of them 
in good condition. ‘The species is smoothly scaled and has somewhat: 
the appearance of the Eastern Platysenta vtdens, but it 1s much paler, 
much larger, broader winged, and with none of the sharp contrasts. 
Everything is vague, and even the white-marked reniform is not 
ageressively conspicuous. It has no very close allies in the genus to 
which I have referred it. 

Type.—Cat. No. 4832, U.S.N.M. 


79. HOMOHADENA CANDIDA, new species. 


Ground color white, more or less overlaid and mixed with smoky and 
black scales. Head with a broad, black stripe across the front. Col- 
lar, with a transverse line of black scales near base, then yellowish, 
smoky, white and smoky shades in succession. Disk powdered with 
smoky and blackish scales. Primaries with the ordinary maculation 
lost or changed to a strigate type. A black streak runs through the 
middle of the wing from base to outer margin. All the usual lines are 
indicated by oblique black lines across the costal region. Transverse 
anterior line marked on inner margin by an oblique blackish streak. 
Transverse posterior line indicated by black, venular, somewhat elon- 
gate dots. The outer portion of the wing is smoky, much darker 
toward the internal angle, and through this darker shading a paler 
subterminal line is vaguely traceable. There is a series of short, inter- 
spaceal black lives in the terminal region. Fringes very broad, inter- 
lined, cut with smoky. Ordinary spots not traceable. Secondaries 
white, semitransparent; a blackish terminal band, broadest at the 
apex, narrowing rapidly and lost a little beyond the middle. Beneath 
white, iridescent, primaries smoky along the costa and forming a broad 
outer band, secondaries with a smoky apex and a narrow terminal line. 

Expanse, 26 mm.~1.04 inches. 

Habitat.—Beeville, Texas, May 15 (i. A. Schwarz). 

A single female, which may not have its best place as a Homohadena. 
It resembles most nearly Oncocenmis atricollaris, but has unarmed fore- 
tibie. The specimen is in fair condition, but the thorax has been 
compressed, causing the collar to project hocd-like. 

Type.—Cat. No. 4814, U.S.N.M. 


80. GNCOCNEMIS CILIATA, new species. 


Ashen gray, with smoky streaks, shades, and powderings. Head 
black powdered in frout and on the vertex. Collar with a smoky and

a blackish transverse line. Thorax irregularly powdered with gray, 
smoky and black scales. Primaries streaked with blackish, smoky and 
white, darkest through the upper half of the median space, with a 
dusky oblique shade at the apex and another at the internal angle. 
Median lines lost. Subterminal line indicated by a series of black and 
erdy streaks, disconnected centrally. A broken black terminal line 
at the base of the very long, even fringes, which are interlined with 
smoky, and cut with smoky and black. Claviform a long, broken black 
streak from base to the middle of the wing, margined on both sides 
with white scales. Orbicular oval, elongate, pointed basally, ringed 
with white, with smoky center. Reniform small, lunate, ringed with 
white and with a pale, central powdering. Secondaries smoky, with a 
vague reddish shading, paler at base. Beneath gray, powdery, with 
small discal spots, but without lines in the example before me. 

Expanse, 22 to 25 mm.=0.88 to 1.00 inch. 

Hatitat.—Colorado desert. 

Two females, neither of them in good condition, but with the macula- 
tion perfectly detined. This is the smallest of the stout species and 
belongs to the strigate series. I have had it for some years awaiting 
additional material, but have received none, and conelude that the 
species is very local. 


81. TRICHOPOLIA SERRATA, new species. 


Ground color a dull, dark, smoky brown, overlaying a luteous ground. 
Head and thorax dark brown, with a few luteous scales intermingled. 
Abdomen dull gray. Primaries with the maculation fairly evident, not 
contrasting. Basal line pale, the margins marked by scattered black 
scales, not well defined. Transverse anterior line geminate, nearly 
upright, ineluded space pale, outer line broken, black, slender, preced- 
ing line hardly darker than the ground. Transverse josterior line 
narrow and black, outer line smoky; in course, outcurved over the 
reniform and almost touching it, only a little drawn in, below. Sub- 
terminal line pale, irregular, broken, without obvious defining shades, 
the veins a little darker through subterminal and terminal spaces. 
Below vein 5a black bar crosses the subterminal space and is con- 
tinued, less obviously, to the outer margin beyond subterminal line. A 
series of black terminal lunules. Orbicular large, round or nearly so, 
of the paler ground color, black ringed. Reniform large, nearly round, 
of the pale ground color, black ringed. Claviform broad, pointed, 
extending nearly across the median space; of the darker, overlaying 
shade, black ringed. Secondaries white, with a narrow, smoky, ter- 
minal line. Beneath white, powdery along the costa, primary with a 
partial outer line; all wings with a blackish discal spot. 

Expanse, 25 to 28 mm. = 1.00 to 1.12 inches. 

Habitat.—Texas, without definite locality. Two males, of which one 
is in very good condition. The antenne are a little serrated, the pro-

protuberant. We have now three species in this genus, one with pecti- 

nated, one with serrated, and one with simple male antenne.

82. LEUCANIA VELUTINA, new species. 


Ground color reddish luteous, washed with red brown, especially 
beyond the middle of primaries. Thorax with a narrow, sharp crest; 
disk carneous. Palpi reddish gray above, deep velvety brown at the 
sides. Abdomen washed with carmine red. Primaries with an irreg- 
war, diffuse purplish shade along the submedian vein. Basal line 
vaguely indicated. Transverse anterior line narrow, single, yellowish, 
a little oblique outwardly to the middle, and then with a small angle 
a little oblique inwardly. Transverse posterior line forming an acute 
angle just below the costa, then evenly oblique to the hind margin; 
narrow, pale, margined on each side by darker red brown. Subter- 
minal line narrow, yellowish, irregular, preceded by a few small, 
obscure dark spots, the terminal space a little paler than the rest of 
the wing. Fringes rust red. A vague dusky median shade line is 
marked below the cell. Orbicular moderate in size, a little irregular, 
annulate with yellow. Keniform of good size, oblique, oblong, sides

outlined in yellow, upper and lower margins obscure. Secondaries — 


semitransparent at base, blackish outwardly, with carmine, interlined 
fringes and a carmine wash on the disk. Under side of body velvety 
dark brown. Primaries brown with a carmine wash, with a blackish 
discal spot and a blackish outer line. Secondaries with a carmine 
powdering along costal margin, apex, and half of outer margin, with 
a broken, dusky outer line and a narrow discal spot. 

[ixpanse, 39 mm.=1.56 inches. 

Habitat.—Biscayne Bay, Florida (Mrs. Slosson). 

The species has the wing form of wnipuncta and its general build. 
The markings are all very narrow, thread-like, perfectly distinct, and 
yet not contrasting. In color and general appearance it is entirely 
unlike any of our described forms, though like some of the southern 
species, from which it seems to be also sufficiently distinet. 

The type and only specimen is a female, lacking antenna but other- 
wise in good condition. 


83. HIMELLA QUADRISTIGMA, new species. 


Ground color fawn gray, varying to reddish or darker according to 
the amount of dusky powdering. Head and thorax immaculate. Pri- 
maries with the ordinary spots black or blackish, contrasting, median 
lines simple, even, narrow, black, with or without an accompanying pale 
shade. Basai line simple, broken, blackish, with or without a following 
paler shade. Transverse anterior line outwardly oblique, a little out- 
curved, and a trifle drawn in on the subcostal and submedian veins,

with or without a preceding paler shading. Transverse posterior line 
outcurved over the cell, evenly oblique below, with or without a follow- 

- ing paler shade line. _ A series of black, terminal lunules, followed by 
a pale line at the base of the fringes. In the darker specimens a paler 

shade extends from the apex through the subterminal space, making a 
vague subterminal line by contrasting with the darker terminal region. 
Orbicular moderate in size, a little irregular, with or without a paler 

annulus, Reniform ale re, centrally constricted and larger below, 
with or without a pale annulus. Secondaries whitish, with a yellow 
tinge and a smoky terminal line. Beneath whitish, powdery, with a 
broken line and black diseal spot on all wings. 

Hxpanse, 27 to 30 mm.=1.08 to 1.20 inches. 

Habitat.—Blutt, Utah, May 30 (Mrs. H. M. Peabody); Santa Rita 
Mountains, Arizona, June 19 (HK. A. Schwarz). 

One male, three females, all from the U.S. National Museum. Like 
contrahens in type of maculation, but the lines are more even and the 
contrasting ordinary spots are characteristic. The variation is in the 
amount of dark overlaying scales which, when most abundant, leave 
a paler border to all the dark markings. 

Type.—Cat. No. 4781, U.S.N.M. 


SELICANIS, new genus. 


Head small, retracted; front smooth, flat, or with a blunt point. 
Tongue weak and short. Palpismall,not reaching the middle of the 
front, terminal joint small. Antenne of the male with joints marked 
with small tufts of cilia or single, longer, lateral bristles. Eyes naked. 
Thorax short, convex, subquadrate, with a small tuft behind the collar 
and a somewhat indefinite bunch at the base. Abdomen proportion- 
ately very long, exceeding the secondaries by one-third to one-half its 
length; without obvious tuftings. Legs short and stout in the male, 
clothed with dense bunches of hair and scales; in the female more 
sparsely clothed, without spinules or other horny armature. Thoracic 
vestiture consists of long, flattened, scale-like hairs. Wings propor- 
tionately short and narrow, with well-marked apices and obliquely 
arcuate outer margin. 

The genus seems to belong with the Orthosiids. Its type is cinereola, 
which is herewith described, and probably the species described as 
Anchocelis digitalis by Grote will also find a place here. Anchocelis 
has a cylindrical frontal protuberance and a spiral, functional tongue, 
which the new genus does not have. 


84. SELICANIS CINEREOLA, new species. 


Mouse gray to fawn brown, powdery, scales of thoracic vestiture 
often white tipped. Head and thorax without markings. Primaries 
with the median lines whitish, the median space obviously darker than 
the rest of the wing; narrow, unusually even and like a broad, dark,

central band. Basal line not obvious. Transverse anterior line well — 
removed from base, a little outeurved, even, margined on each side by — 
a narrow smoky line. Transverse posterior line makes a little outward — 
bend below the costa and runs thence evenly and only a little oblique, 
margined on both sides with a narrow smoky line. Subterminal line, 
when best marked, whitish, a little diffuse, somewhat irregular, dis- 
located a short distance from costa, preceded by asmoky shading. From 
this to entire absence, all intergrades occur. Of the ordinary spots, 
the reniform is usually traceable by a line of whitish scales, but some- 
times all are absent. Secondaries varying from reddish to smoky gray, 
uniform, or only a little paler at the base. Beneath reddish to smoky 
gray, powdery, without markings in the examples before me. 

Expanse, 30 to 40 mm. = 1.20 to 1.60 inches. 

Habitat.—Denver, Colorado, October 12 (Oslar); Glenwood Springs, 
Colorado, October (Dr. Barnes). 

Three males and three females in fair condition. The species some- 
what resembles an exaggerated Telesilla, or a narrow-winged Plagio- 
mimicus; but the structural characters are, of course, distinctive. The 
variation is in size, in ground color, and in the degree of development 
of the subterminal line; and yet withal the species holds its char- 
acteristic appearance.

Head moderate in size, hardly prominent. Eyes naked, large, hemi- 
spherical, prominent. Tongue normal. Palpi very long, exceeding the 
front by nearly the length of the thorax, transversely flattened, vesti- 
ture scaly and directed toward both edges, middle joint much the 
longest, projecting straight forward or a little oblique, terminal joint 
less than one-half as long as the second, clothed in the same way, 
directed obliquely upward. Front with a long pointed tuft, extending 
forward over the base of the palpi. Antenne of the male with long 
lateral bristles. Thorax and abdomen untufted, the former with 
smooth, scaly vestiture. Legs rather long, closely scaled, unarmed 
except for the usual spurs on the tibie. Primaries triangular, short, 
broad, with acute apex and arcuate, oblique, outer border. 

At first sight this seems a Deltoid genus, but the venation of the 
secondaries is strictly 3-1id, though vein 5 is fairly developed. The 
palpi have the scales projecting beyond the edges both above and below, 
forming a two-edged member and thus differing in a second essential. 
We have no previously described genera with which this might be best 
allied, and, pending further discoveries, this might be associated with 
Doryodes, ete. 


85. ANEPISCHETOS BIPARTITA, new species. 


Ground color a pale, inuteous brown. Head and thorax with an 
admixture of gray. Primaries with an even, oblique white line, start-

ing from the costa about three-fourths from base and ending at about 
the middle of the inner margin. Within this, the wing is uniform, 
yellow brown. Beyond the white line is a pale shade which merges 
gradually into an obscure dusky or smoky shading. A subterminal 
line of brown spots is traceable through this shading, in most speci- 
mens. The orbicular is indicated by a black dot. There is a brown 
line at the base of the fringes. Secondaries, uniform smoky brown. 
Beneath, smoky, immaculate. 

Expanse, 17 to 19 mm.=0.68 to 0.76 inch. 

Habitat.—Key West, Florida. 

Four males are before me and I haveseen others. The species seems 
to be not uncommon, and may have been described as a Deltoid, which 
it resembles as well in the simple maculation as in the wing form and 
abnormally developed palpi. 

Type.—Cat. No. 4815, U.S.N.M. 


DIALLAGMA, new genus. 


Head moderate in size, front broad, littie convex, not tufted. An- 
tenn in the male well ciliated, with longer, bristle-like hair on each 
side of each joint; in the female simple. Tongue normal. Eyes 
naked, moderate in size, not prominent. Palpi disproportionately 
stout and long, straight or somewhat oblique, exceeding the head by 
its own length; second joint longest, a little arcuate above, clothed 
with scales directed downward and longer at the tip, so that this is 
very broad when viewed from the side. As the joint is also thickened 
laterally, the palpi diverge and do not form a snout. Terminal joint 
short, stout, subequal, straight or a little oblique upwardly. Thorax 
small, convex, vestiture scaly,.close, forming no tufts. Abdomen well 
exceeding anal angle of secondaries, untufted. Legs unarmed except 
for the usual spurs, which are long and stout, vestiture scaly and, 
though close, quite thick, so that the tibize especially seem heavy. 
Primaries rather long, moderate in width, widening rather evenly from 
base, apex rectangular, outer margin even, fringes long. Venation 
normal. Secondaries proportionate. Vein 5 well marked though 
weaker than the others, from the cross vein rather close to 4, but not 
forming a branch of the median. 

As a whole the moths are somewhat slender and narrow-winged 
closely sealed, and most marked by the heavy palpi. The genus seems 
best related to the Eucalypterid series at present. 


86. DIALLAGMA LUTEA, new species. 


Ground color clay yellow, smooth, with rough black powderings from 
which the markings are formed. Head a little more yellow on the ver- 
tex, palpi chocolate brown at the sides, collar and disk of thorax irro- 
rate with brown; but not otherwise ornamented. Primaries with all 
the lines blackish and more or less broken, a large quadrate blackish 
patch in the middle of the wing, just beyond the transverse anterior

line, forming the most prominent feature. Basal line forming trian- 
gular blackish brown costal spot. Transverse anterior line upright 
or nearly so, blackish, broken, diffuse. Transverse posterior line black- 
ish, broken, single, abruptly and somewhat squarely exserted oyer the 
cell, followed by a slightly paler shade. Subterminal space darkening 
to a blackish shade, which marks the subterminal line by the contrast 
with the paler terminal space; this line only a little irregular. The 
terminal space itself becomes somewhat darker to the margin, on which 
is a series of black, interspaceal dots, the fringes marked by dusky 
cloudings opposite the veins. Orbicular a distinct, round, black dot. 
Reniform very obscure, and indicated only by a variable number of 
black scales. Secondaries smoky, immaculate. Beneath variable; pri- 
maries blackish, with a pale subterminal shading, and this varies to an 
almost even, smoky gray; secondaries whitish, with a discal spot, a 
median, an extra-median, and a terminal band smoky brown or blackish, 
the fringes cut with dirty white and smoky. 

Expanse, 19 to 21 mm.—0.76 to 0.84 inch. 

Habitat.—Charlotte Harbor (Mrs. Slosson); Archer, Florida, July 3 
(Koebele); September (U.S.N.M.). 

Several specimens, representing both sexes, are before me, and I have 
seen others. The species seems to be rather common in some portions 
of Florida, and is not subject to variation except in the relative distinet- 
ness of the black markings. The quadrate dusky patch in the middle 
of the basal third of the primary is characteristic. 

Type.—Cat. No, 4834, U.S.N.M.

HELIODES Guenée. 


Thus far no representatives of this genus have been described from 
our fauna; but I have now before me two species that seem to fit per- 
fectly to Lederer’s characterization. The moths are small, plump, with 
fine, loose vestiture, and short, trigonate primaries. Head with a pro- 
tuberant, bulging front, with a naval-shaped depression in which is a 
short pointed process. Palpi reaching this process, the terminal joint 
a little oblique, with rough, hairy vestiture. yes narrow, small, naked. 
Tongue normal. Antennz in both sexes simple. Tibize without spinu- 
lation or other armature, save the usual spurs; legs short, stout, with 
heavy clothing of scales and hair, not tufted. In habitus the species 
resemble Melicleptria. 


87. HELIODES ANGELICA, new species. 


Ground color of head and thorax black, the fluffy vestiture yellowish 
and sometimes with a carmine shading. Abdomen black, terminal seg- 
ment yellow. Primaries with a blackish ground, over which there is a 
more or less obvious carmine shading, sometimes making the wing abso- 
lutely carmine and sometimes leaving it almost black. An oblique 
yellow band, made up of two contiguous spots, crosses the primaries 


-

beyond the middle. These spots are usually joined, but they may be 
entirely separated and even reduced to smail dots. In some specimens 
a yellowish subterminal line is traceable, and in one example it is com- 
plete; in another there is no sign of it. There may be a yellow or gray 
shading on the costa in the basal space, and there is usually one on the 
costa just before the apex. Secondaries black, fringes yellowish, with 
two oblong, yellow spots, which may be united so as to form an incom- 
plete median band, may be reduced to mere dots, or may be entirely 
absent. Beneath black, the spots of the upper side reproduced in 
white. 

Expanse, 14 to 16 mm. = 0.56 to 0.64 inch. 

Habitat.—Los Angeles County, California, in May. 

Three males and three females, all from the U.S. National Museum 
collection. The line of variation has been indicated in the description, 
and itis not improbable the altogether immaculate examples may occur. 

Type.—Cat. No. 4818, U.S.N.M. 


88. HELIODES RESTRICTALIS, new species. 


Ground color of head and thorax black, more or less overlaid by 
white or yellow scales and by yellow fluffy hair. Abdomen with a ecar- 
mine tinge, which is most obvious laterally, terminal segment yellowish 
brown. Primaries black, overlaid by carmine, with a tendency to a 
covering of whitish scales in the basal space. Median space yellowish 
or whitish, broken by the large reniform, which is of the ground color. 
Fringes blackish, smoky. Secondaries black, immaculate in one exam- 
ple, with a white spot, a little above the middle, in the other. Beneath 
black, primaries with two, secondaries with one white spot. 

Expanse, 13 to 14 mm. = 0.52 to 0.56 inch. 

Habitat.—Butte County, California (Coquillett). 

One male and one female, in fair condition only, from the U. 8. 
National Museum. It is impossible to say just what is the range of 
variation in this species, but it does not tend in the direction of angelica. 
It will probably tend to a broader, pale median space, in which the 
reniform may be completely surrounded. The body beneath is brightly 
clothed with yellow on the breast, while the venter is carmine except 
at the base. 

Type.—Cat. No. 4817, U.S.N.M. 


NARTHECOPHORA, new genus. 


Eyes naked, hemispherical, large, somewhat prominent. Antenne 
in both sexes simple, feebly ciliated. Tongue weak and soft, but of 
moderate length. Palpi very small, drooping, almost aborted. Head 
with clypeus turned up to form a projecting rim, front produced into 
an oblique plate, the lateral corners of which are drawn out into points; 
the vertex continued forward into a keel, surmounting the frontal plate 
and projecting in a point some distance beyond it. Seen when the vesti- 


sa

ture is complete, it seems like three corneous points, the central longer 
and a little above the others. Thorax rather small, oval, convex, the 
vestiture thin, mostly hairy, forming no definite tuftings. Abdo- 
men conic, well exceeding the anal angle of secondaries, smoothly 
sealed. Legs moderate in length, proportionate, smoothly scaled, 
tibie not spinulated, anterior with a slender curved claw at tip. Wings 
moderate, seeming rather frail, because their peculiar maculation gives 
them a thinly scaled appearance. Primaries long, the costa scarcely 
convex, apex somewhat drawn out, outer margin oblique and arcuate. 
Secondaries proportionate, vein 5 a very strong fold, almost midway 
between 4 and 6. 

The genus resembles Acopa in habitus and general appearance, and — 
belongs with it. In frontal structure it resembles Tristyla; but the 
vestiture is not scaly and the tibial armature and weak tongue will 
separate it. 


89. NARTHECOPHORA PULVEREA, new species. 


Ground color a somewhat reddish luteous, evenly powdered with 
blackish scales, so separated that the ground color showing through, 
makes the wing seem semitransparent. Head and thorax immaculate. 
Primaries with a broad, somewhat diffuse band, even or toothed at the 
middle, representing the transverse anterior line. A similar, more dif- 
fuse, narrower, bisinuate band represents the transverse posterior line. 
Reniform a white crescent at the end of the discal cell. Secondaries, 
more whitish, somewhat silky, immaculate, a little more dusky out- 
wardly. Beneath, silky reddish-gray, immaculate, save that on the 
primaries the white reniform shows through from the upper side. 

_Expanse, 21 to 23 mm. = 0.84 to 0.92 inch. 

Habitat.—Tueson, Arizona, July 19, 20, 21. 

Two males and two females, very much alike, save that the females 
are a trifle darker and better marked. The species is so simply orna- 
mented that it should be easily recognizable, even aside from the strong 
generic characters. The examples were taken by Mr. H. A. Schwarz, 
and are from the collection of the United States National Museum. 

Type.—Cat. No. 4783, U.S.N.M. 


PALADA, new genus. 


Head small, closely applied to thorax, though hardly sunken. Front 
rough and protuberant, clothed with short, stiff vestiture. Tongue 
normal. Eyes naked, reniform. Palpi reaching to the middle of front, 
second joint densely clothed, terminal joint short, oblique, obtuse. 
Thorax plump, with a layer of close scales, over which is a fluffy, thin, 
hairy vestiture. Abdomen conic, reaching to the anal angle of the 
hind wings. Legs short, stout, clothed with scales and long hair, tibice 
not spinulated, anterior short and broad; at the tip the inner angle is 
prolonged into a horny, claw-like process; the outer into a short, blunt

spur. Wingsshort and stiff; primaries with the costal margin sinuate, 
distinctly depressed at its middle, apex acute, drawn out, outer mar- 
gin evenly oblique, fringes long, margins even; secondaries, rounded, 
proportionate. 

This little genus of Heliothids is allied to Melicleptria, from which it 
differs by the lack of tibial spinules. The short, broad fore-tibia, the 
protuberant rough front, and the sinuate costa of the primaries form a 
combination that separates it from the other allied forms. 


go. PALADA SCARLETINA, new species. 


Head and thorax black, clothed with fluffy light-yellowish hair that 
gives a hoary effect on a good specimen. Abdomen black, terminal 
segmentluteous. Primaries with basal and subterminal spaces tawny 
to deep smoky brown, median and terminal spaces luteous, the latter 
very narrow, the former superiorly shaded with tawny or smoky. The 
lines are marked by the contrasts in the shading of the spaces. Trans- 
verse anterior outcurved, the edges a little irregular; transverse pos- 
terior evenly bisinuate; subterminal irregular and very close to outer 
margin. Fringes purplish to smoky. MReniform vaguely indicated by 
a somewhat darker shade. Secondaries, evenly black. Beneath, pri- 
maries scarlet, verging to purple, black at base, yellow at the apex; 
secondaries black, with a brown tinge. Breast yellowish, venter red 
brown, the apex yellow. 

Expanse, 17 to 20 mm. = 0.68 to 0.80 inch. 

Habitat.—California; San Diego County, California; Utah. 

Two males and one female, only the latter in really good condition; 
the examples received at long intervals. The two males are the smaller 
and darker, one of them having been in my old collection twelve years 
ago. The species is so strongly marked that it does not seem possible 
to mistake it. 

Type.—Cat. No. 4816, U.S.N.M. 


sot. SCHINIA RENIFORMIS, new species. 


Head and thorax white, vestiture hairy over a scaly base. Primaries 
white at base, merging gradually into a broad transverse anterior band 
of a greenish-gray color, which forms an outward acute angle below the 
median vein. Median space white. Subterminal space greenish gray 
or olivaceous, the margins even, broadest on costa, outwardly curved 
over the cell and then very even to the inner margin. Subterminal 
line broad, white, very even. Terminal space greenish gray, even. 
Fringes white, cut at the tips with greenish gray. Reniform large, 
greenish gray, oblique, centrally constricted. Secondaries white, with 
a variably wide smoky outer band, through which there may be a 
white shade line. Sometimes there is a smoky discal spot. Beneath, 
with the maculation of the upper side reproduced except for the basal 
band of the primaries. 


488 PROCEEDINGS OF THE NATIONAL MUSECM. VOL, XXIL. 


Expanse, 20 to 25 mm. = 0.80 to 1.00 inch. 

Habitat.—Colorado (Bruce); Denver, June 20 (Oslar). 

Six specimens, evenly divided as to sex, and I have seen others. The 
species is allied to cumati/is in appearance and has been confused with 
it; but it is obviously distinet by the large, prominent reniform and 
the very even margins of all the maculation. The gray color has the 
appearance of being veiled by a faint wash of white. 

Type.—Cat. No. 4824, U.S.N.M. 


92. SCHINIA OCULATA, new species. 


Head and collar yellowish, the latter with brown powderings. Disk of 
thorax white, with yellow mottlings. Primaries at base creamy, with 
ocherous mottlings. The broad median space silvery white, without 
band, but with a large kidney-shaped reniform, which is ocherous and 
emphasized with black scales. Subterminal and terminal spaces creamy, 
the subterminal a trifle more gray, at and below the apex a brownish 
patch. A series of small, brown, terminal lunules, becoming lost toward 
the hinder angle. Costa over the reniform, creamy. Secondaries with 
a yellowish tint, with a broad, smoky, outer margin. Beneath, primaries 
with the disk blackish, inner and costal margins yellowish, a yellowish 
subterminal line, and a large blackish diseal spot. Secondaries white 
with a yellow tinge. 

Expanse, 23 mm. ==0.92 inch. 

Habitat.—Rio Verde Mountains, Pheenix, Arizona, August, Dr. Barnes. 

One defective male and one good female. Differs obviously and at 
once from the other silvered species by the absence of a median band. 


93. SCHINIA CILIATA, new species. 


Head yellow in front. Vertex and thorax a mixture of creamy and 
tusty brown scales, vestiture somewhat loose. Primaries ocherous, 
mixed with deep rust brown at base. Then silvery white to a broad 
median band which is similarly ocherous and brown, outwardly a little 
bent on the cell, and separated by a narrow silver line from a broadly 
oval, brown reniform. Beyond this band and reniform spot the wing 
is again Silvery to the powdery, rusty brown, broken, subterminal line, 
beyond which it is creamy white. There is a rusty brown spot on the 
margin below the apex, and a series of brown terminal marks extends 
halfway to the hind angle. Secondaries white, with a narrow, slightly 
dusky outer margin. Beneath, primaries blackish, except along inner 
margin and at apex. Secondaries white, with a blackish spot at the 
inner third of outer margin. 

Expanse, 22 mm. = 1 inch. 

Habitat—Hot Springs, New Mexico, 7,000 feet altitude, August. 
Collection of George D. Hulst. 

One female in excellent condition. This specimen has been in my 
hands nearly ten years awaiting a mate. As none has arrived, it may

be fairly considered as rather rare or at least local. It has a median 
band like conchula, but has also a separate reniform and evident sub- 
terminal line. 

We have now four species referred to Schinia which are largely sil- 
vered on the primaries and would be classed as Tricopis if Grote’s 
generic term could beused. These are conchula Felder anit Rogenhofer 
(chrysellus Grote), aleucis Harvey, oculata Smith, and ciliata Smith. 
The two former are narrower winged and the primaries are more 
pointed than in the latter. In conchula there is no reniform and the 
median band is angulated so as to inelude the space that should be 
occupied by it. In ciliata there is a similar band, but outside of, and 
separated from it, is a large reniform. In alewcis the median band is 
upright, the reniform is entirely separated, the terminal and part of the 
subterminal spaces are dusky, and there is a triangular, silver, ante- 
apical spot on the costa. Finally, the reniform is very large and prom- 
inently contrasting. No effort has been made to ascertain what differ- 
ences there may be in tibial armature. The fact that the term chry- 
sellus Grote must yield to conchula Felder and Rogenhofer has been 
recently pointed out by Mr. Strecker. 


TRIPUDIA LUDA Druce. 
Agrophila luda Druck#, Biol. Cent.-Amer., Heterocera, IT, 1898, p. 491, pl. xcrv, fig. 25. 


Five specimens of this species are before me; two of them from 
Sonora, Mexico, 40 niles from the Arizona line; two marked “ Ariz.,” 
without other information, and one, taken by Mr. E. A. Schwarz, marked 
Tucson, Arizona, May 18, 1898. It seems probable that this will prove 
not uncommon on both sides of the border. 

The original reference to Agriphila can hardly be sustained if Leder- 
er’s limitation of the genus is correct. The genera of this series need 
further study; but for the present I prefer to change the reference 
originally made by Mr. Druce te Tripudia, because the species seems 
congeneric with our species, and because I have two others which I 
prefer to describe under that head. 


94. TRIPUDIA BALTEATA, new species. 


Head and thorax ashen gray, the disk and posterior tuft of scales a 
little darker. Abdomen with rather a prominent dark scale tuft on the 
third segment, yellowish at base. Primaries ash gray at base, followed 
by a broad, oblique, bright luteous band which extends to the middle 
of the wing. This is followed by ashen gray, with a brownish overlay 
to the paler gray fringes. The outer edge of the yellow band is mar- 
gined by a black line which, on the cell, forms an outward loop to 
include the reniform shading and merges with the transverse posterior 
line. The latter is single, black, and below its merger with the line 
previously described is irregularly angulate. The subterminal space is 
shaded with brown, the subterminal line being indicated by pale, rather 


490 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL, XXII. 


pinkish shadings which are irregular and disconnected. The terminal 
space is gray, with a broken black line at the base of the gray and brown 
mottled fringes. Secondaries smoky brown, paler at base. Beneath pale 
reddish luteous, secondaries more whitish, both powdery and darker 
shaded along the costal margin. 

Expanse, 14 to 15 mm. = 0.56 to 0.60 inch. 

Habitat.—Santa Rita Mountains, Arizona, May 29 and June 16, Mr. 
KE. A. Schwarz. 

Two females in good condition. The species is very characteristic 
and should be recognizable. It resembles the 7. flavofasciata of Grote. 

Type.—Cat. No. 4780, U.S.N.M. 


95. TRIPUDIA LUXURIOSA, new species. 


Head and thorax silver gray, with darker, reddish brown scales 
intermixed, disk and posterior bunch of scales on thorax, brown; 
abdomen gray with yellow tinge. Primaries silver gray at base to the 
transverse anterior line, which is single, brown, broken and irregular, 
the basal line being traceable over the costal region by pinkish seales. 
From the transverse anterior line to the inner edge of. the brown median 
shade the space is whitish, shaded with pink, basally. The median 
band is brown, edged with black scales, twice dentate on each side, the 
teeth being opposite, so that we have two constrictions and three 
expansions. Silvery scales edge this band outwardly and lighter scales 
extend to the deeply sinuate transverse posterior line, which is brown, 
incomplete, and single. Subterminal line silvery white or creamy, 
irregular, with two square insets, which are silvery, and three blocks of 
blackish scales above, between and below these insets. Apex brick 
red, rest of terminal space reddish brown. The long fringes are irregu- 
larly mottled and marbled with black, gray, and brown. Orbicular 
barely indicated by dusky scales before a constriction of the median 
band; the reniform better marked by an indefined dusky spot beyond 
it. Secondaries smoky brown, the fringes more gray. Beneath yellow- 
ish, mottled with black. 

Expanse, 11 to 13 mm. = 0.44 to 0.52 inch. 

Habitat.—Arizona; Santa Rita Mountains, Arizona, June 14, 1898 
(BH. A. Schwarz). ick 

Two females; one of them, taken by Mr. Schwarz, very fresh, the 
other, an old example, a little faded and without definite locality. The 
description is from the fresh example, which is really very handsome 
and richly colored. This species should also extend into Mexico, but 
has not been recognized as described.

T alpochares daria Druck, Biol. Cent.-Amer., Heterocera, IT, 1898, p. 497, pl. xcv,fig.29. 


This seems to be rather a common species in the southwestern United 
States. I have it from several points in Texas, from as many collectors; 


No. 1203. NEW NOCTUID MOTHS—SMITH. AQ] 


from Hot Springs, New Mexico, 7,000 feet altitude (Hulst collection); 
Oracle, Arizona, July 7(H. A. Schwarz), and some point in Southern Cal- 
ifornia, from Dr, H. H. Behr. The type lecality is Jalapa, Mexico. The 
specimens vary somewhat in the amount of contrast and in the ground 
color; but in general they are lighter or darker ashen gray, the reniform 
ereamy or whitish, the light shade extending to the costa and forming 
a triangular contrasting blotch which will call attention to the species. 

The generic reference is questionable if our own species of Thalpo- 
chares are correctly referred. 


PARORA, new genus. 


Head rather small, well applied to the head, though hardly retracted. 
Byes naked, hemispherical, not prominent. Palpi long, obliquely pro- 
jecting beyond the head by more than its own length; second joint 
longest and evenly thickened; third slender, cylindrical, rounded at 
the tip. Front only a little convex, with a short, pointed, hairy tuft. 
Tongue strong, normally developed. Thorax rather short, quadrate, 
only a little convex, with close scaly vestiture. All the tibiz unarmed, 
except for the usual spurs. Abdomen cylindric, smoothly scaled, a 
little exceeding the anal angle. Primaries broad, costa and inner 
margin arched, apex rectangular, the outer margin a trifle excavated 
below it and a little produced at the middle. Secondaries proportion- 
ate, vein 5 as strong as any other, but from the cross vein and well 
removed from 4, not really forming part of the median series. 

The genus at first sight tends to the Erebiid or Poaphilid series, but 
the moderate discal cell and the location of vein 5 of the secondaries 
indicates its place to be a little higher in the series. 


96. PARORA TEXANA, new species. 


Ground color a very pale luteous. Head and collar chocolate brown, 
thorax with a somewhat paler brown discal stripe, which may become 
partly lost. Primaries without strong contrasts, the most prominent 
mark being a smoky cloud which extends from the reniform to the 
transverse posterior line or a little beyond it. Transverse anterior line 
narrow, brown, upright or a little oblique, with three almost even sin- 
uations. Median shade line a little broader, but more diffuse at the 
edges, darker, parallel with the transverse anterior line and a little 
within the middle of the wing. Transverse posterior line slender, 
blackish, followed by a paler shade, defined outwardly by a few dark 
scales, so that the line seems geminate. In course it is broadly outcurved 
over the cell, and only a little drawn in, in the submedian interspace. 
Subterminal line lunulate, slender, dark, preceded by a pale yellow 
liiie at the base of the fringes. Orbicular a small blackish dot. Reni- 
form moderate in size, upright, a little constricted in the middle, 
yellow. Secondaries smoky with a reddish shading, a little paler at 
base. Beneath more yellow, practically immaculate. 


492, PROCEEDINGS OF THE NATIONAL MUSEUM. VOL, XXII. 


Expanse, 26.to 27 mm.=1.48 to 1.52 inches. 

Habitat.—Brownsville, Texas, June 11 (Townsend); San Diego, 
Texas, June 12 (Schwarz); Corpus Christi, Texas (Dr. Barnes). 

Three females, two of them from the U.S. National Museum. None 
of the examples are perfect, but on all of them the characters are well 
recognizable. The markings are not well written and the only notable 
feature is the dark shading of the primaries just beyond the reniform, 
which in one example extends almost to the apex. 

Type.—Cat. No. 4777, U.S.N.M. 


97. SYNEDOIDA SUBTERMINA, new species. 


Ground color pale luteous, varying to grayish. Head and thorax 
immaculate. Palpi with second joint black at base. Antenna with a 
rosy flush outwardly. Primaries with costa a little reddish, vestiture 
smooth and even. Basal line single, black, broken on the cell, con- 
trasting. Transverse anterior line marked by a black or blackish cos- 
tal spot, and beyond that reduced to scattered black powderings. 
Transverse anterior line geminate on the costa, smoky, traceabie as a 
very narrow thread over the cell and then Jost. Subterminal line dis- 
tinct, broad, yellow, a little sinuate, marked by preceding black points 
and scales. A dusky oblique shade from vein 6 to the apex. A series 
of more or less obvious terminal dots on the veins. Orbicular wanting. 
Reniform blackish, upright, narrow, inner margin straight, outer a 
little incurved, forming the most prominent feature of the wing. Sec- 
ondaries whitish at base, darkening to a blackish outer border, the 
fringes smoky. Beneath pale, reddish powdery, all wings with a discal 
spot. 

Expanse, 35 to 37 mm.=1.40 to 1.48 inches. 

Habitat.—San Diego County, California. 

Two females in good condition, one of them with a grayish bloom 
over the luteous ground. The species somewhat resembles Tenio- 
campa at first sight, and is most nearly allied to the Taniocampa vegeta 
of Morrison, which is the Cissusa spadix of Cramer. The obvious sub- 
terminal line, contrasting reniform, and otherwise lost maculation will 
serve to distinguish this species.

ANTIBLEMMA Hibner. 


Two species referred to this genus are in our lists: ineracta Walker= 
canalis Grote, which ranges from New York into the West Indies, and 
guttula Henry Edwards, so far only recorded from Georgia. The two 
species are similar, guttula having a very large bluish reniform which 
gives it at first glance a strikingly different appearance from ineracta; 
yet the resemblance in other directions is close. Among the specimens 
- that I have been placing with inexacta, I find aseries of four examples, 
male and female, which are uniformly smaller, much darker in ground

color, and with the primaries much less excavated below the apex. 
These I am unable to identify with any other described form and have 
named minorata. Allare from Florida. Another specimen, from Ari- 
zona, is yet different, the ground color becoming bluish gray, while a 
darkening of the space between the median shade and the transverse 
posterior line forms a broad smoky band which crosses both wings; 
this I have called fasciata. The secondary sexual characters are the 
same in each instance so far as appears by a superficial examination. 


98. ANTIBLEMMA MINORATA, new species. 


Ground color a somewhat dull fawn brown, more or less black pow- 
dered. Head and collar chocolate brown or darker, thorax and abdo- 
men concolorous. Primaries sometimes quite even, sometimes strongly 
powdered, the maculation variably evident. Transverse anterior line 
slender, blackish, inwardly oblique, outcurved in the interspaces, 
rarely complete. Transverse postérior line nusty yellow, preceded and 
sometimes followed by a blackish line or shade, with a long, acute 
angle between veins 6 and 7, inwardly oblique and a little incurved to 
the inner margin, one-third from the inner angle. Subterminal line a 
series of more or less diffuse, interspaceal spots in a bisinuate course; 
sometimes connected by a dusky shade which may fill the space between 
transverse posterior and subterminal lines to the angle in the former. 
The shade may then be continued from this angle to the apex, making 
an apparently straight line from apex to the hind margin. Median 
shade blackish, diffuse, a little irregular, angulated on the cell, more 
or less broken. Orbicular a small black dot, more or less completely 
margined by white scales. Reniform moderate in size, irregular, some- 
times scarcely defined, sometimes black and contrasting. Secondaries 
with a median line which is a continuation of the transverse posterior 
line of the primaries. The median shade of primaries crosses the sec- 
ondaries at basal third and is broken or obscure; in one case only an 
elongate spot near the inner margin. Subterminal line similar to that 
of primaries and as variable, but a little farther from the margin. 
Here also the subterminal space is sometimes dark filled, so as to form 
a broad band. ‘There is a small, black, discal dot. Beneath paler, 
more irrorate and powdery, with a scalloped, irregular, outer line, a 
black dot representing the orbicular, and discal spots on both wings, 
and a white, linear spot representing the reniform on primaries. 

Expanse, 28 to 29 im.=1.12 to 1.16 inches. 

Habitat.—Florida, April and June 15 (Hulst); Glenwood, Florida 
(Barnes). 

Two males and two females; none of them in good condition and no 
two alike. In one ease the powdering is almost wanting and the reni- 
form is contrasting. In another the maculation is almost all wanting; 
a third has the subterminal space on both wings dark filled, while the 
fourth has this shading broken into spots.

99. ANTIBLEMMA FASCIATA, new species. 


Ground color, mouse gray with a bluish tinge. Head and collar 
defective in the specimen before me, but apparently not red brown. 
Thorax and abdomen concolorous. Transverse anterior line red brown, 
slender, single, very evenly zigzaged, inwardly oblique. Transverse pos- 
terior line very narrowly yellow, margined on each side with chocolate 
brown for its entire course, which is asin minorata. Median shade broad, 
blackish, a little diffuse, as a whole parallel with the transverse poste- 
rior line, the intervening space between the two brown filled; lightly 
so on costa, densely so toward the inner margin. A brown shade 
extends from the angle of the transverse posterior line to the apex. 
Subterminal line an irregular series of interspaceal blackish marks, 
varying in size and shape, forming a dusky shading opposite the anal 
angle and another opposite the cell. Orbicular a blackish dot. Reni- 
form obscured in the median shade’ band. Secondaries with the trans- 
verse posterior line of primaries continued across at the middle, the 
median shade crossing at one-third from base, the interval brown filled 
and with a central discal black dot. Subterminal line crossing as an 
irregular, dark, broken, diffuse shade, best marked just above the anal 
angle. Beneath, reddish gray, powdery, disk of primaries darker, more 
powdery, with a white discal spot on all wings. 

Expanse, 29 mm.=1.16 inches. 

Habitat.—Arizona; Hulst collection. 

The type, belonging to the Rutgers College collection, is a male in 
rather poor condition, but so obviously distinct that description seems 
warranted. 

100. BOMOLOCHA VEGA, new species. 


Ground color smoky brown, powdery. Head and thorax unicolored 
darker brown. Palpi oblique, a little curved in all my specimens. 
Abdomen pale, smoky. Primaries as a whole darker to the median 
shade, thence with a somewhat more luteous, paler shade; interrupted 
in some examples by a darker subterminal shade. Transverse anterior 
line upright, irregular, broad, diffuse, only a little darker, preceded by 
a paler shade. Transverse posterior line irregular, indistinct, smoky, 
outcurved over the cell, with a small inward sinuation below. Median 
shade somewhat irregularly sinuate, best marked by the difference in 
color between it and the paler following shade. Subterminal line very 
irregular, toothed, angulated and sinuate, black, broken, preceded by 
black scale shadings varying in extent, but never great. A series of 
pale, terminal, interspaceal somewhat lunate spots. Fringes with a 
pale interline, beyond which they are cut with light and darker shades. 
Orbicular small, round, dusky, not defined and hardly contrasting. 
Reniform is an indefined, pale oval, at the end of the cell. Secondaries 
even, smoky. Beneath, even, rather pale smoky, all wings with a dis- 
cal spot.

A NEW BIRD OF PARADISE, 
IBAY JRO lob, Net (Oiuneyrda = 1Bs5\ ale 


In looking over the Museum series of Paradiseidze, Mr. J. H. Fleming, 
of Toronto, who has made a study of this family, noticed a specimen of 
Cicinnurus which, as he pointed out, differs from the King Bird of 
Paradise, Cicinnurus regius (Linneus), in several important partic- 
ulars. Through the kindness of Mr. Robert Ridgway, Curator of the 
Division of Birds, Iam enabled to present a description of this beautiful 
species, which I propose to call the Crimson Bird of Paradise. 


CICINNURUS LYOGYRUS,!' new species. 


Specific characters.—Differs from C. regius (Linnzeus) in having the 
pectoral shield nearly four times as long as in the latter, almost as long 
as broad; frontal plumes shorter, not projecting forward beyond 
middle of bill and not obscuring contour of skull; tail emarginate 
instead of rounded; outer web at end of central tail-shafts only two- 
thirds as wide near base, the width uniform for the greater portion of 
its length, instead of narrowing rapidly to tip, much more loosely 
coiled, the apical portion of naked, crossed tail-shafts divergent instead 
of convergent. The crimson of back is darker, crown and forehead 
orange-vermilion instead of orange-chrome; pectoral tufts darker and 
subterminal buff line on each plume much narrower, darker, and less 
conspicuous; pectoral shield, except a narrow edging on lower border, 
and tips of central tail-feathers grass-green instead of emerald-green, 
and tips of pectoral plumes yellowish emerald-green instead of gold- 
green. The primaries are also a duller orange-rufous. 

Description.—Above glossy crimson, darker than in C. regius, the 
head pale orange-vermilion; feathers of the crown and forehead short, 
not obscuring the contour of the skull, the frontal feathers not extend- 
ing forward beyond middle of bill; a dark green, almost black, spot 
above and bordering the eye. Throat, and sides of head and neck, 
dull crimson with purplish reflections, the feathers on lower border of 
throat narrowly tipped with buff, forming a convex line; fore neck and 
upper breast with a broad shield of metallic grass-green 65 millimeters 
in length, the feathers of lower border narrowly tipped with metallic 


‘Ave, Lloose; ytpos, whorl, referring to the tips of central tail-shafts.

emerald-green; on each side of upper breast is a tuft of long, apiecally- 
rounded, broccoli brown plumes, most of which are tipped with brilliant 
metallic yellowish emerald-green, each feather with a very narrow, 
inconspicuous buff line and a second, still narrower, coppery-brown 
one just before the green tip; outer webs of some of these plumes slightly 
washed with orange-rufous near base; lower breast, belly, and under tail- 
coverts white; under wing-coverts white. Scapulars crimson. Wings 
orange-rufous, the outer webs of primaries and outer secondaries edged 
with orange-vermilion, the inner secondaries and secondary coverts 
heavily washed with that color, primary coverts less heavily so. Upper 
tail coverts extending almost to tip of rectrices, orange-rufous, washed 
with orange-vermilion; tail emarginate, broccoli brown, the outer webs 
of feathers bordered with orange-rufous. Central pair of tail-feathers 
with their shafts crossed near base, greatly elongated, the webs very 
narrow basally, and entirely wanting beyond tips of other rectrices, 
except on the apical 70 millimeters of shaft, where there is a loosely- 
coiled, metallic grass-green outer web, whose greatest width is 8 milli- 
meters; width of this web uniform for the greater portion of its extent; 
apical portion of naked, crossed shafts divergent. The green of these 
outer webs, as also that of pectoral tufts and shield, appears violet 
when held in Gadow’s ‘‘ Position C.”' Wing, 200 mm.; tail (exclusive 
of central shaft-wires), 78 mm.; central pair of tail-feathers (straightened 
to extreme tips), 330 mm.; culmen,42 mm.; tarsus, 50 mm.; middle toe, 
o7 mm.

It is unfortunate that the specimen is not accompanied by a more 
definite locality, so that some hght might be thrown upon the habitat 
of the species. It would appear that it is either very rare or that it 
inhabits some little-explored portion of New Guinea proper or, possibly, 
some other island of the Papuan group. 

The Hon. Walter Rothschild has recently ? separated specimens of C. 


'In this position the bird is held on nearly the same level with, and between, the

regius from Jobi Island under the subspecific name coccineifrons. This 
form is said to differ from true regius *‘in having the short feathers on 
the bill produced farther towards the tip, thus leaving a smaller piece of 
the bill unfeathered; in having these feathers a little longer, much 
darker, and of the same colour as the back.” There are about thirty 
specimens of regius in the National Museum; all of these, however, 
seem to be typical, consequently I have had no opportunity of examin- 
ing the subspecies. 

The figures of the old pre-Linnzean authors, though very poor, un- 
doubtedly refer to C. regius.

SYNOPSIS OF THE NAIADES, OR PEARLY FRESH-WATER 
MUSSELS. 


By CHARLES TORREY SIMPSON. 
Aid, Division of Mollusks. 


In 1836 Dr. Isaac Lea published a Synopsis of the Family of Nai- 
ades, which was followed by a second edition in 1838, a third in 1852, 
and a fourth in 1870. In this work Dr. Lea did not attempt to make 
any systematic classification, but divided the species into two great 
genera, Margaron and Platiris, and subdivided these genera into sub- 
genera, and finally into smaller groups founded on the presence or 
absence of a dorsal wing, and on the form and sculpture of the shell. 
This arrangement was regarded by Dr. Lea as merely a temporary one, 
to be used until a knowledge of the soft parts could be obtained, on 
which to base a permanent classification. 

Several other attempts at a classification of the Naiades have been 
made, and among these is that of Swainson in 1840, who believed that 
the whole family formed a circular group, that by beginning at a cer- 
tain point in it the species or genera would be found closely related to 
others, and these to others still, and that by following up the chain of 
relationships one would be brought back to the place of starting. My 
studies have not borne out Swainson’s conclusions, but I have adopted 
two of his divisions of the Unionide, the subfamilies Unionine and 
Hyriane. His subfamilies Anodontine and Alasmodontine have no 
value, and the subfamily Iridinz belongs in the family Mutelidie. 

In 1847 Gray gave a classification of the Naiades in his List of Recent 
Genera, in which he divided them into three families: Unionide, with 
the genera Anodonta, Margaritana, Monocondylea, Unio, Barbala, Lam- 
proscapha, Anodonta, Byssanodonta, and Glabaris; Mutelidse with 
Mutela, Leila, Pleiodon, Paxyodonand Prisodon, and Mycetopodide, with 
the genus JJycetopus. 

Troschel, in 1847, proposed a classification in which the genera were 
founded on anatomical characters, and though for lack of knowledge

he was led into several serious errors, his work has proved an important 
aid in classification. 

H.and A. Adams followed with a classification in 1857, in which they 
recognized the families Unionide and Mutelide, dividing the former into 
two subfamilies, Unionine and Mycetopine, and giving a list of the 
then known species. 

Agassiz, in 1852, published a classification of the North American 
Unionid, based more especially on the anatomy, but much of his 
work was hasty and careless, and as a result his groups are, for the 
most part, heterogeneous assemblages of unrelated species. 

Tn 1893, von Ihering published his Najaden von San Paulo, in which 
he showed that while certain of the Naiades began their existence on 
hatching from the egg as a glochidium, with a bivalve shell capable of 
containing the soft parts, others developed into a lasidium, with three 
segments, the middle one alone having a single shell. He showed that 
the presence or absence of siphons by which the Mutelide had been 
separated from the Unionide was not a constant character, even in indi- 
vidual species, and placed the genera which he believed to have glo- 
chidia in the family Unionidze, and those with lasidia in the Mutelide. 
I consider this the most important discovery that has yet been made in 
the study of the Naiades. 

In 1896 the writer published a classification of the Naiades, based 
largely on his studies of shell characters. In that it was shown that 
throughout one great group all the genera had shells with schizodont 
hinge teeth or vestiges of them, and in the rest, a smaller group, they 
all had taxodont teeth, or vestiges of them. As all the genera whose 
shells have schizodont teeth were believed by von Ihering to possess a 
glochidium, and those with taxodont teeth have a lasidiwm, it seemed 
as though there was a natural division of the Navades into two families 
Unionide and Mutelidee. 

Some years ago the Rey. and Mrs. L. T. Chamberlain, son-in-law and 
daughter of Dr. Lea, suggested to Mr. Dall that a new edition of the 
Synopsis, or if necessary a new work, should be prepared, and for this 
purpose they generously offered to contribute such sums as might be 
needed for the purchase of material to add to the great collection left 
by Dr. Lea to the U.S. National Museum at his death, and for li: erature 
that might be required in preparing the work. As the writer had made 
a special study of the Naiades, the task of preparing the new Synopsis 
fell to him. Since then Mrs. Chamberlain has been called away by 
death, greatly regretted, but her husband has continued to cheerfully 
furnish all the needed funds for carrying on the work to completion. 

While the labor of preparing the synopsis has been arduous, and 
while it has been impossible to obtain material needed in many iImpor- 
tant groups, or all the necessary literature, I feel that my opportuni- 
ties for study have been exceptionally good. I have had constant 
access to. the great collection of Dr. Lea, the finest, no doubt, ever

made of the Unionide, and containing more types than any other in 
existence. In addition to this the U.S. National Museum possesses a 
large collection, including many types, and for the most part carefully 
determined by that able student Dr. James Lewis, as well as the entire 
Jeffreys collection. A great amount of valuable material has been 
lately added to it, including the Morelet collection of Naiades, a set of 
Burmese shells from Fea, a series of New Zealand forms from Suter, a 
large number of species from von Ihering, from South and Central 
America and Mexico, the entire series of types of Mr. S. H. and B. H. 
Wright, and types from many other sources. The writer has personally 
examined the collections of Say, Conrad, and Rafinesque, in the Acad- 
emy of Natural Sciences in Philadelphia, as well as the excellent alco- 
holic series which was the basis of all of Dr. Lea’s studies. Through 
the courtesy of the officers of the New York State Museum of Natural 
History the entire collection of Naiades of Dr. Gould was loaned to the 
U.S. National Museum, in order that he might study it. Besides this 
he has examined the fine collections of Mr. Bryant Walker, Mrs. George 
Andrews, Prof. A. G. Wetherby, and a great amount of material 
belonging to Mr. William A. Marsh, Mr. B. H. Wright, and many 
others. He has made critical examinations of the soft parts of more 
than four hundred species, American and foreign. 

Aside from the careful work of Lea, Troschel, and Pelseneer, little 
has been done in the way of studying the anatomy of the Naiades. The 
soft parts of a good many foreign species have been examined, and 
descriptions published which do not describe. Authors have gone into 
details of the color of the organs and of insignificant characters, but 
have paid no attention to really important points. 

In my paper on The Classitication and Geographical Distribution 
of the Pearly Fresh-water Mussels,' I placed a great variety of forms 
under the generic name Unio. Since that time additional knowledge, 
gained largely from a study of the soft parts, has led me to the belief 
that it would be best to dismember this genus somewhat as the old 
group Helix has been dismembered by Pilsbry. Ordinarily the soft 
parts of most of the Unionide show but slight differential characters, 
but at the time when the ovules pass down into the gills a most remark- 
able change in those organs generally takes place. In the Anodonta 
edentula of Say, short, horizontal ovisacs are developed, which run 
directly across the animal, and which at maturity break through the 
outer walls of the outer gills and pass with their young eutire into the 
water. In the forms typitied by Unio anodontoides the young are con- 
tained only in very distinct vertical or oblique ovisacs in the hinder 
part of the outer gills; in Unio crassidens, pictorum, and the like, the 
embryos fill the entire outer gills, forming thick, smooth pads; in Unio 
metanevrus, trigonus, multiplicatus, and allied forms, they occupy all 
four of the branchie throughout. In Unio phaseolus the smooth outer

504 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. xx. 


gills begin to be crimped as they are being filled with embryos, until 
when full, they become a series of marvelous folds. In U. irroratus 
several ovisacs in the center of the outer gills grow out to a great 
length, become filled with young, and are closely coiled. In U. cor- 
nutus a few central ovisacs develop so as to project below in a long, 
straight flap. In all the South American and Australian Unios, so far 
as is known, the inner gills alone, as a rule, are filled with young, and 
this is probably the case with the species of the Ethiopian region and 
most of those of southeastern Asia. After the young have passed out 
into the water the gills of all the species change back into their ordi- 
nary condition, and when not gravid there is great similarity in those 
of most of the species formerly classed as Unios. 

These peculiar evanescent characters, assumed when the gills are 
transformed into marsupia, seem to be quite constant, and I believe 
they can be used as a basis for the foundation of genera. When these 
are once discovered and understood it will be found, on careful exami- 
nation, that there are minor shell characters that correspond with those 
of the marsupia, and which help us in placing certain forms of whose 
anatomy we know but little. Thus the principal shell characters of 
such species as Unio trigonus, metanevrus, and plicatus are much like 
those of U. gibbosus, crassidens, and buckleyi. But in the former set 
all four gills will be found to be filled with young in the gravid female, 
while in the latter only the outer ones are full. And the former have 
generally shorter, solider, more inflated shells and deep beak cavittes, 
while the latter have longer, lighter shells, which have shallow beak 
cavities. In Anodonta edentula the ovisacs are short and run across 
the gills; in the very similar looking A. /erwssaciana the outer gills are 
filled with oblique ovisacs, and the inner have (at least in some cases) 
more or less ovules. The beak sculpture of these two species is very 
different. 

From the earliest period in which the Naiades have been studied to 
the present time it has been claimed by some that the sexes were sepa- 
rate, by others that the animais were hermaphroditic. Recent careful 
studies by such men as Sterki, Taylor, Kelly, and others appear to 
demonstrate that in the more highly organized Unionidée (those which 
have two forms of shells, and have the ovisaes in the hinder part of 
the outer gills) the sexes are always separate. In the more simply 
organized Unionide (those with but one form of shell and with the 
embryos occupying the entire gill) the sexes may or may not be 
separate. 

Further study has shown me that the provinces established in 
the paper I have quoted hold good as there laid down. There is evi- 
dently a very close relationship between many of the unionoid forms of 


southeastern Asia and tropical Africa. So close is this relation that — 


the two regions might be united if it were not for the fact that a large

I have hesitated long before placing a considerable number of the 
species of Southeastern Asia in and near North American genera. I had 
hoped to be able to examine the soft parts of a number of these Oriental 
forms, but have been disappointed, and as nothing is known of the 
anatomy of most of them I have been compelled to classify by shell 
characters alone. It is certain that the beak sculpture of a large num- 
ber of Naiades of this area is essentially concentric, and not zigzag 
radial, as it is in most of the furms of the Oriental region. The shell 
characters of the ponderous Chinese Uniones are certainly much like 
those of Quadrula in the form, the teeth, the beak sculpture, and 
especially the deep, compressed beak cavities. A great number of fossil 
forms from the Tertiary strata of Asia and Hastern Europe seem to 
show the closest relationship to the American Quadrulas. Hyriopsis, 

~Cristaria, Chamberlainia, and Pilsbryoconcha seem to be related by 
shell characters to the alate forms of Lampsilis, and even the strange 
Pseudospatha of Africa would appear to belong here. 

I recognize about one thousand species and 82 varieties of Unionide, 
having reduced tothe synonymy a great many names that most authors 
have believed to stand for valid species. Of these, 533 species and 55 
varieties belong in North America and 101 in South America. The 
list contains 117 species of Mutelide and 11 varieties, and of these 80

Total: 61 genera of Unionide; 11 genera of Mutelidie. 


I am inclined to believe with von Ihering that the primitive beak 
sculpture of the Unionid was radial, and in two species of Unios from 
what are believed to be Triassic or Permian strata of the Staked Plains 
of Texas,' which are probably the oldest forms known, the beaks clearly 
show strictly radial sculpture. Four other species trom the same lot 
are not in condition to exhibit this character. 

Now I take this to belong to the simplest, earliest, and most lowly 
organized form of unionoid life. I believe that the earlier Unios had 
the young contained in the inner branchiv alone, that there has been 
a gradual development from these primitive forms with simple, dull- 
colored, smooth shells, those of the male and female being alike, with 
radially sculptured beaks, the Hndobranchs, up to the highest forms of 
to-day, with concentric, doubly looped beak sculpture, with highly 
painted shells, in which those of the male and female are very different, 
with the young contained in distinctly marked ovisaes in the hinder 
part of the outer gills alone, the Hxvobranchs. 

The data for following these developments and the migrations of the 
Naiades are meager so far as fossil materiai is concerned. But, fortu- 
nately, while among the higher orders of life genera and even families 
appear, develop, grow old, and become extinct in a single geological 
age, the Unionide have held on unbroken from the Triassic or prob- 
ably an earlier geological age until now, and while there has been slow 
progress in the development of higher characters the primitive forms 
have not died out. I know of no important type of the family among 
the fossil species that may not be found somewhere to-day among the 
living ones. They seem to have migrated to a certain region, made a 
slight advance over the characters of their predecessors, aud to have 
continued down with but little change until to-day. When a new 
mInigration was made the same thing was enacted again. 

If the Unionide originated in North America during the Triassic or 
Some earlier period we may suppose that some members of the family 
mInigrated into South America during that or at a later period. All the 
species of that family in South America have radial beak sculpture 
(except Callonaia and Prisodon, in which the beaks seem to be smooth), 
and the young are contained in the inner gills alone, so far as we know. 
In some cases this sculpture is strictly radial; more often we find the 
central or all the bars curving a little toward each other below, and 
one or two of the middle pairs coalescing, the first move toward concen- 
tric beak sculpture. By an old,now partly submerged land bridge in the 
Antarctic region it is probable that a migration took place from South 


1Proc. U.S. Nat. Mus., X VIII, 1896, pp. 381-385. 


508 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL, XXII. 


America to New Zealand and Australia, and slight changes in the way of 
progress are shown there. The beak sculpture is still radial, but the bars 
are decidedly curved toward each other below; they become slightly 
broken or nodulous, and each set is generally removed from the other a 
little, so that a space in the middle of the young shell issmooth. The 
young are contained in the inner gills, though Suter reports a few in 
the outer gills of one or two species and in all these Southern Hemi- 
sphere forms the shell has a dull color, and is nearly or quite rayless. 
Another migration took place to Southeastern Asia, and from there 
there was another to tropical Africa, possibly from Southern India 
over an old but now lost landway. In the forms of this region the 
beak sculpture becomes irregularly and variously zigzag radial, the 
surface is nodulous in many cases, and the shell is often bright colored 
and painted. Some of the recent species, such as Unio crispisulcatus, 
show nearly strict radial sculpture all over the shells; others which 
I have placed in the genus Lamellidens have almost such sculpture as 
is seen in the beaks of the Australian forms. In others the sculpture 
becomes slightly nodulous. Reasoning from analogy, and the few 
gravid specimens I have examined of these forms with the zigzagged 
beak sculpture, I presume that they all carry the young in the inner 
gills, though it is quite probable that some of them may have them in 
all four gills, and this would be a step in an upward direction. Some 
of these Asiatic and African forms with zigzag sculpture are quite 
short, inflated, and solid, and, in general, show characters strongly 
allied to those of our heavy Mississippi Valley forms (the latter of 
which I placein Quadrula), the various members of the genus Parreysia, 
for example. ; 

It is quite probable that from such forms the genus Quadrula sprung; 
that it developed in Asiatic streams, where it still seems to be repre- 
sented. In the Tertiary strata of eastern Europe and in parts of 
Asia this genus seems to be abundantly represented. It is a little dif- 
ficult to say from some of the living Asiatic forms whether the beak 
sculpture should be called sharply, doubly looped, or zigzag radial, 
and the same thing may almost be said of some of our North American 
forms. There probably existed at that period an old land way across 
from northeastern Asia to northwestern North America, and one which 
lasted a long time, or it may have been submerged and then reappeared 
again, for through long ages this has apparently been a highway for 
migrating Unionide. I think it not unlikely that the immediate progeni- 
tors of the magnificent and diversified series of Uniones found fossil in 
the Laramie beds came over from Asia among the earlier migrations; 
for it is a significant fact that among the Uniones of the Laramie for- 
mation in the United States we have a number of species which in general 
form closely resemble these recent Asiatic Parreysias, and that their 
beak sculpture is decidedly zigzag radial, just as it 1s to-day in these 
oriental forms. Associated with these Laramie species are others in 


No. 1205, SYNOPSIS OF THE NAITADES—SIMPSON. 509 


which the beak seulpture is somewhat concentric and of a peculiar 


pattern seldom found among living Uniones, the ridges being nearly 
straight below and sharply pointed behind in a chevron-shaped pattern. 
I take it that the next step of progress was the development of the 


genus Pleurobema, or forms which are nearly allied to it; though the 


strange, smooth, elongated, wedge-shaped Cuneopsis, with its remarka- 
bly deep beak cavities and often distorted shells, and the eurious 
Gibbosula seem like Quadrulas making an effort to shape their shells 
something like those of Unio. In Plewrobema the shell is solid and 


rather triangular, the beaks are high and typically well forward, the 


beak sculpture is broken, but most nearly concentric, the beak cavities . 
are shallow, and the young occupy only the outer branchie. There are 
great numbers of species I should refer to this or closely allied genera 
in the oriental tertiaries, and many of them are knobbed. To-day the 
genus is confined to the Mississippi Valley and the northern drainage 
of the Gulf of Mexico, and all the species are smooth except P. wsopus 
and P. varicosa, which I place in the genus with some hesitation. 

This genus has an immense development in the waters of the Ten- 
nessee drainage, becoming less abundant as we advance northward, 
until in the Ohio River and its tributaries only three species are found, 
Pleurobema clava Lamarck, P. varicosa Lea, and P. wsopus Green. In 
the Tennessee and Cumberland systems all the species except the two 
last mentioned belong to the group typified by P. clava. In the Ala- 
bama River drainage and a few adjacent streams emptying into the 
Gulf there is a great development of this genus, but none of the species 
belong to the clava group. Now, if the genus migrated into the Ten- 
nessee system from the northwest, and it seems quite probable that it 
did, its presence in the Alabama River system would seem to prove the 
theory entertained by some geologists that the Tennessee formerly 
emptied into the Gulf, flowing down into what is now the Coosa River 
and into the Alabama. Additional proof of this is found in the fact 
that quite a number of the common Mississippi Valley species, such as 
Unio tuberculatus Barnes, U. rectus Lamarck, U. trigonus Lea, U. 
anodontoides Lea, U. ebenus Lea, and others are met with in the 
Tennessee, the Coosa, and the Alabama River systems, and Unio con- 
radicus and U. cumberlandianus, Tennessee River forms, occur in the 
Alabama system. That this southern outflow of the Tennessee ceased 
a long time ago is shown by the fact that in the Alabama drainage all 
the northern species of Uniones have a peculiar aspect, and several 
entire groups of Pleurobema have developed, which are distinet from 
anything found in the Tennessee. 

It is probable that the true Unios and their allies were next developed, 


with simple oval to elongated shells, and moderate beaks showing 


quite a variety of sculpture. It is generally concentric, being inclined 
to follow the growth lines, but sometimes the ridges are broken, and 
again they are somewhat doubly looped. The young occupy the outer 


510 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXII 


gills only, forming a pad-like marsupium. The genus is now found 
throughout a large part of the Palearctic region and North America 
generally, excepting the Pacific drainage. The Unios of what seems to 
bethe Gibbosus group are abundant in the Tertiary of eastern Europe. 
Unio davilai from Roumania is almost exactly like U. gibbosus, a recent 
species of the Mississippi Valley, and there were species no doubt closely 
allied in the Tertiary of the western United States. There were forms 
in Eastern Europe which seemed to connect Unio and Pleuwrobema, some 
of which were like P. clava and formed a connecting link with Quadrula. 
There were Quadrulas showing relationship with our Q. trigona, rubi- 
ginosa, pustulosa, pyramidata, and other forms. Psilunio craviovensis 
looks much like our Plewrobema wsopus and there are other striking 
examples of old forms resembling recent ones. 

Now, in Quadrula, Unio, Alasmidonta, and some of the other allied 
genera we not unfrequently see species or specimens which have the 
ordinary concentric or doubly looped beak sculpture, and in addition to 
this a number of fine, regularly radiating ridges in front or behind, or 
sometimes at each end of the ordinary sculpture, an atavistic develop- 
ment, probably. In some groups this character is quite constant; in 
others it is only occasionally seen. I have never noticed it in any of the 
higher genera in which the male and female shells are different. 

Up to this point the male and female shells had been essentially alike, 
and the ovisacks were not distinctly outlined, but formed smooth pads, 
the marsupium occupying practically the whole gill. In the American 
waters probably, a great change now began to take place in some of the 
Unionide. The ovisacs of many forms became distinctly marked out 
by a deep sulcus; a constriction developed in some instances around 
near the base of the marsupium, inside and out, so that the lower end 
of the ovisacs resembled little bulbs, and these were often filled with 
pigment of a different color from the rest of the ovisac. Ptychobran- 
chus, with its folded marsupium, may have developed from Unio; 
Cyprogenia and Obliquaria, with their narroy, central marsupia, and 
Dromus, in which it is hung all around the outer gills in short, distinet 
ovisacs, would seem to have descended from Quadrula by their shell 
characters. Inallof these the shells of males and females are essentially 
alike. In Medionidus there is sometimes quite a well-marked swelling 
at the central or post-basal part of the female shell which is absent in 
the male, but sometimes it is impossible to separate the shells of the 
two sexes. The marsupium consists of irregular ovisacs just behind 
or almost at the center of the outer gills. Inthe strange Tritogonia the 
female shell differs remarkably from that of the male, having developed 
a broad, posterior wing, filled with a flap of the mantle, while that of 
the male is swollen, and truneate behind. Of the marsupia of this 
strange form I know nothing. Oboraria, with short, solid, full shells, 
sometimes having a slight post-basal inflation in those of the female, 
and Plagiola, with triangular shells, often showing the distinction 
between male and female, recall to some extent Quadrula in shell ehar- 
acters, but have the marsupia in the hinder part of the outer gills 
alone. The ovisacs are distinct, and there is a sulcus below, and this 


No. 1205. SYNOPSIS OF THE NATADES—SIMPSON. 511 


is the highest type of a branchial uterus. Lampsilis is a step farther 
on, with oval to elongated shells, generally highly colored, with, as a 
rule, a decided post-basal swelling of that of the female, without (in 
most cases) a strong post ridge, and the beak sculpture consists of 

rather numerous, delicate bars, Seed in two distinct (anterior and 
posterior) loops. 

Throughout the entire Mississippi Valley, a portion of the Atlantic 
drainage, in most of the streams flowing into the Gulf of Mexico, in east- 
ern Mexico, and Central America there is found an extensive group of 
Uniones for which I have used the name Proptera of Rafinesque. Nearly 
all the shells are more or less dorsally winged, the beak sculpture is 
feeble, the epidermis is dull, the teeth are often imperfect, and they have 
a row of dorsal scars running obliquely downward and forward. The 
nacre generally is some shade of purple, and though the female shell 
may Show a decided post inflation,it may be wanting. The ovisacs 
are usually fine and numerous, and are placed in the posterior ends of 
the outer gills. I have given this group subgeneric rank under Lamp- 
silis. Now,it would seem probable that North America was the field 
in which these remarkable developments in the character of the Union- 
ide had taken place, for I know of no fossil species elsewhere showing 
any of these higher characters. If, as I have elsewhere suggested, 
there is a relationship between Proptera and the Cristarias, Hyriopsis, 
Pilsbryoconcha, Chamberlainia, and Pseudospatha of the Old World, 
then I should think it likely they, or their progenitors, had migrated 
thence from North America some time during the early or middle ter- 
tiaries. It is possible that the Cristarias, Hyriopsis, and the like, or 
closely related but now extinct groups, may have originated in ori- 
ental waters, and that the Propteras, and the typical Lampsilis, may be 
their offspring. 

Truncilla marks the highest development of Naiad life, and may 
be taken to be the latest. Its shells are smooth and generally highly 
painted, the beak sculpture is fine and doubly looped, the hinge teeth 
are well developed. The post-basal area is very distinctly marked out 
and developed in the female. In most cases the shell of this part in 
the female is thin, of a different texture from the rest, often radially 
ridged, and decidedly toothed on its edge. There is usually a surpris- 
ing difference in the shape of the shells of male and female aside from 
this, so much so that one would never suppose that they belonged to 
the same species, unless he traced the growth back to the young shells, 
_which are quite alike in the different sexes. The marsupium is like a 
large kidney, very full, and totally different in appearance when 
gravid from the rest of the gill. It appears to be protected by a great 
flap which grows out from the mantle covering it, which is here double. 
The genus exhibits a great variety of form, so much so that several 
good subgeneric groups seem well marked out, and we must believe it 
has been in existence for some time. 

Much of the foregoing may be mere conjecture; much is undoubt- 
edly founded on fact. I believe that the living forms of the Unionide 
show a gradual development from the simplest, lowest, and earliest 


512 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXII. 


types up to the highest, most recent, and most complicated, and stand 
as a sort of index to the progress of the family in the past. 

LT have not been able to study the Mutelide as carefully as I have the 

Unionide. All the species are foreign, and while I have seen the soft 
parts of a few South American forms, I have never had the opportunity 
to examine the anatomy of a single African species. I Lave not been 
able, from what knowledge I have obtained, to discover any consider- 
able anatomical or conchological differences between the Mutelid genera 
of Africa and South America which might be used to separate the 
family into subfamilies. 
- [ have treated the families of the Unionidee and Mutelidee together in. 
this work because they bave both been classed as Naiades. But the 
remarkable differences in the embryos, that of the former family being 
a glochidium with a bivalve shell inclosing the soft parts, and that of 
the latter a lasidium divided into three segments with a single shell 
on its middle section, and the shells of the one family having schizo- 
dont teeth, while those of the other have taxodont teeth, seem to show 
that the two great groups are not very nearly related. 

Instudying the Naiades I have been greatly perplexed on accountof the 
unsatisfactory and confused condition of much of the literature. Harlyin 
this century Rafinesque collected the Unionide extensively in Kentucky 
and published a large number of genera, minor groups, and species. 

It is probable that there will always be differences of opinion with 
regard to his work, just as there have been in the past. His figures are 
more like those made by children, or the caricatures drawn by aboriginal 
tribes, than the creations of an intelligent naturalist, and the deserip- 
tions are too brief in many cases to give any clear idea of the species. 
The work in the continuation of his monograph is even worse than that 
in the body of the paper, and tribes, genera, and subgenera are mingled 
in bewildering confusion, and all these are placed under two great genera, 
It is impossible in many cases to tell what his meaning is. I have care- 
fully gone over his so-called types in the Academy of Natural Sciences 
in Philadelphia, making notes and sketches, and stating the names 
by which they are commonly known. Four times, separated by long 
intervals, I have studied his original descriptions, with specimens of 
the same species as these so-called types, in an attempt to determine 
his species, each time writing down my conclusions, and I believe that 
quite a number of his species will have to stand. There can be no doubt 
whatever that many of his so-called types are not types at all, as they 
do not fit the descriptions by any stretch of imagination. 

In applying generic, subgeneric, and sectional names | have used 
those which have been previously applied wherever it has been possible 
to do so by the process of elimination, in order that no claim of priority 
might be urged for them. 

A most unfortunate dispute arose among our earlier conchologists in 
regard to priority of names, one in which a great deal of ill feeling 
was displayed. I have endeavored wherever it was possible to ascer- 
tain the exact date of publication of these disputed names and to 
credit the species to the earliest described. In some cases it has been 


~ No. 1205. SYNOPSIS OF THE NATADES—SIMPSON. 513 


impossible to tell which of two names appeared first, and in such cases 
I haveused that which seemed to be best known. 

Many of the species of Lamarck stand on about the same foundation 
as those of Rafinesque, having only a brief description and no fig- 
ures. Dr. Lea on at least two occasions went over the types of most 
of Lamarck’s species and has published his conclusions in the Obser- 
vations, and I am obliged to abide by his decisions, never having seen 
the types myself. 

One of the most perplexing problems has been the work done by 
European conchologists, and especially by the so-called new school of 
France. Previous to 1870, the date of issuance of Lea’s last edition of 
the synopsis, thousands of names had been applied to the few species 
of Europe. But this work was conservative and reasonable compared 
with that of the new school since then. I have devoted much time 
and study to this fauna and its literature. To me it seems that 
there are not more than eighteen or twenty species of Unionidie found 
in Europe, judging by the same standards I have applied to species 
elsewhere. Nearly all the authors seem to be more or less at sea as to 
certain forms of this area, and the reasons for this are probably their 
want of striking characters and their extreme variability. Unio picto- 
rum, tumidus, elongatulus, and platyrhynchoideus have been often taken 
for each other. Margaritana margaritifera has repeatedly been mis- 
taken for the very similar looking M. crassa, and each of these has been 
hopelessly confused with Unio batavus. 

I have endeavored to consider names applied before 1870 in my 
synonymy. I have made no effort to do this with those applied by 
authors to the forms of Europe since that time, as I do not believe that 
any new species of Unio, Margaritana, Anodonta, or Leguminaia have 
been found there in the last thirty years. The genus Colletopterwm (1881) 
is a doubtful one and is very likely only an mutation of the excessively 
variable Anodonta cygnea. In 1892 Arnould Locard, one of the great 
lights of the new school, stated that there were 208 species of Unios 
and 250 Anodontas in France alone.! 

Life is too short and valuable to be wasted in any attempt at 
deciphering such nonsense, and I have not even cumbered the pages 
of this work with a list of these new species. Those interested can find 
them in the works of Westerlund and Kobelt. 

In cases where the new school has worked on the fauna of Africa or 
_ Asia, I have done the best I could to straighten out the synonymy. 

I have not attempted to make any analytical key to genera and other 
groups, because [ do not believe that it is possible to construct a key 
that will be of any real service to the student. At least four-fifths of 
the shells of the Naiades have the beaks so eroded that it is impossible 
to form any idea of what their sculpture is like, and the soft parts are 
inaccessible to the average student and collector. These are both vital 
characters that must be used in classification. The general arrange- 
ment of the groups down to genera is shown in the following table:

In the preparation of this work I have received uniform courtesy and 
kindness from students and collectors generally. I am under especial 
obligations to Mr. Edgar A. Smith, of the British Museum, for exam- 
ining and reporting on the original manuscript of Solander, and to Mr. 
H. A. Pilsbry, of the Academy of Natural Sciences of Philadelphia; 
Mr. A. G. Wetherby, of Magnetic City, North Carolina; Dr. H. von 
Ihering, Museo Paulista, San Paulo, Brazil; and Mr. H. Suter, Christ 
Church, New Zealand, for repeated assistance and advice. Mr. L. E. 
Daniels, of La Porte, Indiana; Mrs. George Andrews, of Knoxville, 
Tennessee; Hon. J. D. Mitchell, of Victoria, Texas; Mr. Berlin H. 
Wright, of Penn Yan, New York; Mr. Bryant Walker, of Detroit, 
Michigan; Dr. W.S. Strode, of Lewistown, Illinois; Mr. H. M. Kelly, of 
Mount Vernon, Iowa; Mr. William Moss, of Ashton-under-Lyne, Eng- 
land; and many others have contributed valuable material for study. 


SYSTEMATIC ARRANGEMENT OF THE NAIADES, 


Family UNIONID 2. 


Shell nacreous, with a thick epidermis; beaks usually sculptured, 
often showing the remains of the nuclear shell; ligament opisthodetic; 
hinge with or without teeth, though with vestiges of them in every 
genus; when present schizodont and arranged as pseudocardinals and 
laterals; palleal line usually simple; prismatic border ordinarily narrow. 

Animal with labial palpi almost always wider than long; anal opening 
usually separated from the superanal; embryo a glochidium, the soft 
parts being inclosed in a bivalve shell, and borne in the inner or outer 
or all four leaves of the branchie. 


Subfamily UNIONIN A, Swainson, 184.0. (Hixobranchiz.) 


Shell having essentially concentric beak sculpture. 
Animal with labial palpi somewhat drawn out, projecting posteriorly ; 
embryos borne in the outer or in all four gills. 


HETERO GE WN A=: 


Male and female shells different, the latter inflated in the post-basal 
region; beak sculpture usually doubly looped; embryos contained in 
ovisacs separated by a sulcus and occupying the hinder part of the 
outer gills. 


Genus TRUNCILLA Rafinesque, 1819. 
(Type, Truncilla triqueter Ratinesque. ) 


Truncilla RAFINESQUE, J. de Phys., Chimie, Hist. Nat., LX XXVIII, 1819, p. 427. 


Shell rounded or oval, solid, inflated, generally smooth and rayed, 
with delicate beak sculpture which has a tendency to be doubly looped, 
that of the female having a very decided inflation in the post-basal 
region, which is thinner than the rest of the shell, of different texture, 
often toothed, and usually radiately sculptured; laterals double in 
each valve, the inner in the right valve smaller. Animal generally 
having the inner gills united to the abdominal sac; female with a 
heavy flap of the mantle which fills the post-basal swelling of the 
shell, and which has an inner ridge inside at some distance above 
the edge; marsupium very distinct, occupying the swollen part of the 
shell.

‘Four specimens of this species are in the U. 8. National Museum collection, from 
the Connasauga River, Georgia, three of which are males, with a form something 
like that of 7. penita; the fourth is a young female, which distinctly shows a 
vadiately ridged post-basal swelling. 

?These are in continuation of Monography, 1831, p. 4. 

3Lea changed his name lenis to lenior, probably because Conrad had previously 
used the former for a species of Unio, which is no doubt a young ventricosus.

Male shell having a wide, radiating, shallow depression in front of 
the posterior ridge; that of the female having a small, rounded, well- 
defined, radial post-basal swelling. Animal with marsupium occupy- 
ing the greater part of the outer branchie; mantle enlarged below; 
branchial opening, with few papille. 


(Group of Truncilla sulcata.) 


Shell elliptical, beaks high and well forward, male shell not radiately 
striated posteriorly. 


1This may be 7. triquetra. 

2 According to Binney, Unio nexus was first published in December, 1831, (Bib. N. 
Am. Conch., I, p. 266), and Scudder states that the fourth volume of the Transac- 
tions, containing Lea’s description of Unis arceformis, was published at the latter 
end of 1831, and acknowledged by correspondents as received that year (Bib. of pub- 
lications of Lea, 1885, p.3). As I am not able to say which has precedence, I prefer 
retaining the well-known name of Lea rather than that of Say, which is less known.

'T have seen only the type of this species, apparently a young female, which is a 
reddish buff-colored, shining shell, somewhat more elongated than 7. haysiana, but 
which probably groups with it. 


522 PROCEEDINGS OF THE NATIONAL MUSEUM. VoL. XX. 


Subgenus PILEA Simpson, 1900. 
(Type, Unio personatus Say.) 


Male shell with a wide, shallow, radiating depression in front of 
the posterior ridge, that of the female with a rounded, foliaceous 
swelling at the posterior base. Animal with post basal flap of mantle of 
female very heavy; ovisacs not extending to the top of the marsupium. 


(Group of Truncilla personata.) 


Shell inflated, rather solid, nearly as high as long; female not having 
a central depression, post basal swelling smail.

perplexus,” in the Continuation of a Monograph in October, 1831, which I can not 
identify. I do not know which name appeared first, but I think it best to retain 
the well-known and properly described name of Dr. Lea.

1Dr. Lea claims that the animal of this form is lighter colored than that of per- 
plexus, and quotes Mr. Clark, of Cincinnati, who states that this is known there as 
the White Mouth. The shells seem to absolutely biend together, and I have 
observed a wide range of color in the animals of a number of species of the genus.

Genus LAMPSILIS Rafinesque, 1820. 
(Type, Unio ovatus Say.) 


Lampsilis RAFINESQUE, Aun. Gen. Sci. Phys. Brux., 1820, p. 298. 


Shell oval to elliptical, smooth or slightly concentrically sculptured, 
usually without a posterior ridge; epidermis generally smooth and shin- 
ing, often brilliantly rayed; beak sculpture, for the most part, consist- 
ing of fine, parallel ridges, which show a tendency to fall into an ante- 
rior and posterior loop; hinge with one or two pseudocardinals and 
one lateral in the right valve, and two pseudocardinals and two lat- 
erals in the left; female shell having a moderate and gradual inflation 
in the post-ventral region opposite the marsupium. Animal with the 
inner gills usually attached nearly or quite their entire length to the 
abdominal sac; marsupium occupying the hinder part of the outer gills; 
ovisacs distinct, separated by sulci, rounded below, having a fold near 
their bases, the whole projecting below the inner gills; mantle edge 
double and thickened, often swollen behind into a sort of flap in the 
female. 

Section LAMPSILIS Rafinesque. 


(Type, Unio ovatus Say.) 


Shell inflated, rather thin, shining, sometimes having a posterior 
ridge; beak sculpture coarse, consisting of a few, more or less, parallel 
ridges, which scarcely fallinto loops. Animal having the mantle of the 
female usually toothed and thickened on the post-basal portion, which 
develops into a large, curious flap when the gills are filled with ova.

‘Lea says this is so close to U. ventricosus that it would be well to unite them. 
Foot note in Synopsis, 1870, p. 41. 

>This is, | am sure, a fine male U. ventricosus Barnes. Dr. Lea is inclined to this 
opinion in a footnote on p. 118 of the Transactions. 

‘Conrad refers this species to Rafinesque. From the latter author’s figure and 
description of Lampsilis cardium it is evident that it is a member of the ventricosus 
group, but whether it is the U. ventricosus of Barnes, the U. capax of Green, or some 
other species, [am unable to determine. Conrad and some other authors believe it to 
be Barnes’s species. 

4 The type in the Philadelphia Academy is a young U. ventricosus. 

° The type is a diseased individual, and is probably a compressed male ventricosus. 

° J believe this to be merely a rather delicate, dark-colored variety of ventricosus, 
which inhabits the southwestern part of the Mississippi drainage.

1Tt is hard to tell just what this is, as Conrad does not figure or describe it. He 
states that while it is probably excavatus it is not certainly so, and he does not think 
it wise to displace Lea’s properly described and figured species for it. 

2 Lea’s name was preoccupied by Valenciennes (Encyc. Meth., II, 1827, p. 151, pl. 
COXLVIU, fig. 5) for what is probably U.radiatus. I change it to binominatus. 

3 The first edition of Nicholson’s Encyclopedia is dated 1816, fide W. G. Binney, 
Bib. N. Am.Conch., I, 1863, p. 25, and by Lea, Synopsis, 4th ed., pp. 154, 159. 

4The figures are very probably taken from U. ventricosus.

1At the time I published the L. brittsi I believed it to be a valid species. Since 
then I have seen additional material which seems to be a connecting link between 
it and L. breviculus. JI can not be certain as to the relationships of this form, which 
seems on the one hand to have characters belonging to the typical section of Lamp- 
silis and on the other to be related to L. spatulatus and L. pleasi. 

2The systematic position of this species is a little uncertain. In the form of the 
shell and the teeth it seems to belong in the Ventricosus group, but the texture and 
broken rays apparently ally it to the Ligamentinus group. The soft parts agree best 
with those of members of the former assemblage, so I place it here. 

31 do not know what this is, nor where it belongs, but it is certainly not a true 
Anodonta. The shell, according to Conrad’s figure, is rayed throughout, and iooks 
very much like a young U. ventricosus. He says that it has a callus resembling an 
incipient tooth; that it inhabits the Black Warrior River, and that it is very rare. 
It is just possible that it is related to some of the so-called Margaritanas of the 
Southern States, such as W. spillmani, but I think it more likely some young form of 
the Ventricosus group in which the hinge has been injured. I place it here with the 
greatest hesitation.

'The type of De Kay’s variety is a delicate shell with peculiarly pallid brown 
epidermis, slightly rayed, and having a rose-colored nacre. This form is often desti- 
tute of the fine tinting of the nacre, and sometimes becomes quite dark, even bronzy 
or brownish black. It is common in the lakes of the St. Lawrence drainage. 

2This and L. borealis A. F. Gray are doubtful species which seem to stand between 
L. luteolus and radiatus. ‘This form is nearer luteolus, while Gray’s species approaches _ 
more nearly to radiatus.

'Probably only a thin, slightly rayed or rayless variety of L. hydianus. 

2T doubt if this is distinct from Approximus. 

3Dr. Lea places this in the synonymy of Unio lecontianus Lea. I have never seen 
an authentic shell, but the figure given by Conrad in the Journal seems to me more 
like Lampsilis obtusus, and I am inclined to think it is a small male specimen of this 
species having reversed laterals. 

4There is only a single specimen in the Lea collection, the type, an old, rather 
thin, eroded, large shell, in bad condition, but which, I feel sure, is claibornensis.

1A peculiarly humped form of ligamentinus, common throughout the southern 
range of the species, may bear the above name. y 

2A somewhat puzzling species, of which male specimens often approach closely to 
Obovaria ellipsis in form, but the pseudo cardinals are always stumpy and never longi- 
tudinal, as they generally are in that genus. It is probably an aberrant form, 
closely related to L. orbiculatus. The females are more inflated in the postbasal region 
than in any other member of the group. 

31 have seen only one specimen of this, the type, which is an exceedingly puzzling 
form. The hinge line is injured and curves in strongly in front of the beaks, where 
there is a large, irregular lunnle. and the pseudocardinals are compressed. It may 
be a young, diseased orbiculatus.

1 Lea places this species in the synonymy of his Unio interruptus, in the Synopsis. 
The latter was not published until 1838. 

2The type is an old female teniatus, very solid, and but slightly rayed. 

3Lea states in the above citation that this species has radial beak sculpture. The 
beaks ot his type are slightly eroded, having the appearance of somewhat rayed ridges, 
and I have seen the same thing in the eroded beaks of Unio rotundatus Lamarck, 
bnt it is not true beak sculpture. Many Unios when decomposing exhibit throughout 
their shells a somewhat radial structure, and that is what is shown in this case.

1 Said to be of Rafinesque, 1820. I can not be positive whether Rafinesque’s descrip-

inches. I therefore use the name applied by Lea, his shell being properly described 
and figured.

—— — 


1 Lampsilis anodontoides becomes thinner and more delicate in the waters of the 
eastern Gulf drainage, and in Florida assumes the form called by Lea Unio floridensis. 
The type of the latter is not in the Lea collection. 

2¥Figured and the name (supplied by the writer) given by Smith in Bull. U.S. Fish 
Commission, but not described. 

3As this species has generally been confounded with the very closely allied L. ano- 
dontoides of Lea, it is a little difficult to be certain in all cases which form authors 
have referred to. 

4A species which seems to combine some of the characters of L. anodontoides and 
cariosus, but which probably shonl| e placed here. 

> This species seems to stand partly between L. rectus and L. anodontoides. In the 
character of color both of nacre and epidermis the former is quite widely separated 
from the latter, though specimens of rectus from Michigan and other northern local- 
ities sometimes have a tawny epidermis. In L. australis the nacre is silvery, and 
the color of the epidermis approaches to some extent that of anodontoides.

Entire Mississippi drainage; Alabama River drainage; Red River of 
the North; St. Lawrence system. DeCamp’s Unio anodontoides, reported 
from Michigan, is a tawny colored variety of this species according’ to 


Walker. 
(Group of Lampsilis nasutus.) 


Shell elongated, thin, compressed, with a distinct posterior ridge, and 
drawn out to a long, pointed beak behind; epidermis rather dull, olive 
green, and feebly rayed; beaks low, sculptured with fine, close-set 
ridges, which are slightly looped in front and are parallel with the axis 
of the shell behind; hinge teeth delicate and compressed; nacre bluish; 
female shell not greatly produced in the post-basal region. Animal 
with the marsupium often occupying the greater part of the length 
of the outer gills posteriorly; inner gills free or united to the, abdomi- 
nal sac.

1Barnes only gives an outline of his shell, which appears to me more like his U. 
gibbosus than rectus. However in deference to the opinions of Hildreth, Lea, and 
others, I place it in the synonymy of L. rectus. Hildreth’s description answers fairly 
well to rectus, and it was submitted to Barnes for his inspection. 

2Lea believes this to be a distorted rectus. I am not quite certain of it.

St. Lawrence drainage; streams flowing into the Atlantic south to 


North Carolina. 
(Group of Lampsilis subrostratus.) 


Shell elliptical to elongate, distinctly pointed behind, the point well 
above the middle of the height, that of the female conspicuously 
swollen at the posterior base and obliquely truncated behind; epider- 
mis varying from olive to brown, generally more or less rayed and 
slightly roughened; beaks not prominent, sculptured with fine, deli- 
cate, parallel bars, which are somewhat looped in front and generally 
descend obliquely behind; pseudocardinals usually compressed; nacre 
bluish to purple. Animal with inner gills often more or less free from the 
abdominal sac; posterior base of mantle of female generally toothed.

when quite young shows very delicate and beautiful rays.

appeared in the Synopsis first, and under the generic name Margarita.

' Dr. Lea states in the Synopsis in the above reference that Say’s U. subrostratus is 
identical with his iris. He is certainly mistaken. 

> Lea places Unio opalinus Anthony (Am. J1. Conch. II, 1866, p. 146, pl.vt, fig. 2) in the 
synonymy of the above species. It is an oval, compressed, greenish-yellow shell 
according to the figure and description, and seems to have been injured anteriorly. 
I can not tell what itis. It is credited by Anthony to Michigan.

1Tt is doubtful whether ang: is more than a variety of the preceding. In AOE. 
it has a rather more cylindrical shell, less rayed, and more decidedly and suddenly 
thickened in front than iris, but there are intermediate forms. 

*After carefully comparing again and again large series of specimens, I confess 
that I can not possibly separate the large number of so-called species I have united 
under this, the oldest name. It may seem a little strange that a species should be 
found in the Ohio River area and Gulf drainage, but recent research has proven 
that a large number of our common Upper Mississippi Valley and Ohio River forms 
are found in the Coosa, Alabama, Black Warrior, and adjoining streams. There is 
some variation in the brightness of the painting of a number of these so-called 
species, and in the form of different specimens, but no more than is found in many 
other abundant, widely-distributed forms, and the figure on pl. m1 of the New 
Fresh-water Shells fairly well represents the general manifestation of the males of 
this species.

1 Lea has only a single specimen in his collection. -I consider it a species of doubt- 
ful validity. 

2Doubtfully valid. More regularly elliptical than nebulosus, and the dorsal and 
basal lines are more nearly paraliel. 

*1 have only seen the type, a miserably eroded, broken shell, part of which is 
missing, but I have no doubt that it is the same thing as regularis.

1 Certain ale Syste of it, eae differ so remar ae from foes of the females 
and from any other known Naiades that it might be supposed that they belonged to 
an isolated group. Other male shells, however, differ but little from the females, 
and in L. perpurpureus, a species so close to L. trabalis that it is often difficult to 
separate them, the male shells differ but slightly from those of the females. 
Through this former species the group seems very closely related to that of ellipst- 
formis, and so on to the assemblage typified by L. iris.

1T am not aware that any description of Ravenel’s species has ever been published. 
In his catalogue, he gives it this name, and refers to his manuscripts only. Speci- 
mens that he gave Dr. Lea, which are credited to him from the Santee canal in pencil 
on the shells, are undoubtedly modioliformis. Other specimeus from another locality, 
which Lea has put with these, and has called Unio tenerus Ravenel, are undoubtedly 
L. prevostianus Lea. It was these latter specimens which caused me to be mistaken 
in the identity of Unio tenerus in my paper in Proceedings of the United States 
National Museum, XV, p. 416. 

2One lot in the Academy of Sciences is the same as the exiguus of Lea, another is 
the same as Lea’s nashvillianus. Conrad’s figure, which is not very good, agrees 
fairly well with the former, but is certainly not the latter.

2This seems to be equivalent to a male subellipsis of Lea, of a little more solid, 
evenly oval or elliptical form than the type. I do not think it worthy of a varietal 
name, as there is every possible gradation between these shells. I formerly placed 
exiguus, rutilans, and subellipsis in the synonymy of modioliformis (Proc. U.S. Nat. 
Mus., XV, 1892, p. 414), and in a young state they seem to be exactly alike, as a geu- 
eral thing; but the examination of a large amount of additional material since 
wien has led me to believe that the latter may perhaps be distinct. 

5 Probably a young specimen, rather wide at the posterior end. 

4A smaller, shorter, fragile form, generally having a rather dark epidermis, and 
purplish nacre. It is a southern variety, and gradually merges into the type in the 
Chattahoochee region.

(Group of Lampsilis amygdalum.) 


Shell rather small, obovate, inflated, epidermis varying from smooth 
and shining to somewhat cloth-like, ashy green to blackish, but always 
showing green tints when seen through transmitted light, indistinctly 
rayed; beaks rather high, sculptured with fine, parallel bars, arranged 
in a double loop, that in front being large and rounded, that behind 
small and rather pointed below; hinge teeth compressed; nacre irides- 
cent behind. The greatest height of the shell is just behind the center; 
its greatest diameter is just in front of it, or at a point just behind the 
beaks; the posterior end is often pointed and somewhat raised. Animal 
with the marsupium large, reaching far below the inner gills, and having 
a black border; inner gills united to the abdominal sac throughout; 
anal opening smooth or only slightly crenulate.

1 Having carefully compared the type of this, a large specimen, with amygdalum, 
I have no doubt that both are the same species. 

2'The name concavus applied by Lea was, I believe, used previously by Zelebor for 
what seems to be U. tumidus.

1 Dr. Lea has only two specimens of this shell, both in very bad condition—dead 
and eroded. I have been much inclined to believe that it was a form of L. amyg- 
dalum, but recently a specimen in better condition submitted for my inspection by 
Mr. B. H. Wright would seem to show that the two are distinct. 

2A doubtful species. The type is the only specimen I have ever seen which I can 
refer with any certainty to this species. It is a smali, rather solid shell, and may be 
an unusually heavy L. amygdalum.

Shell small, inflated, obovate, rather solid, covered with a thick, dark, 
often cloth-like epidermis, which is rayless or only feebly rayed; beak 
sculpture consisting of rather strong, concentric ridges, which form, as 
a general thing, only a single, rounded loop in front, and are strongly 
curved upward behind.*? Pseudocardinals compressed, smooth on the 
inside, generally reflexed upward, somewhat torn on the edges. Shell 
quite commonly pointed posteriorly, that of the female truncated 
obliquely on post base. Animal with the marsupium consisting of a 
few large ovisacs (8 to 13); inner gills wholly or in part free from the 
abdominal sac; female often having «a well-developed caruncle on the 

mantle below the branchial opening.

were badly eroded. 

* Krroneously spelled Corunculina. 

> Occasionally there is a vestige of a posterior loop, and I have seen it perfectly 
developed, especially in specimens of L. haleianus. The beak sculpture of this group 
is remarkably like that of the Tetralasmus group of eee though the two assem- 
blages are not at all closely related. 

+A rather delicate variety, but I hardly think -worthy of a varietal name. The 
species varies from being quite slender to short, wide, and inflated.

Alexandria, Louisiana; eastern Texas. 


1A nie ered sour form from southwest Texas may bear this name. 

2Barnes’s outline shows a small shell, evenly rounded posteriorly. I believe that 
this character of being rounded behind is constant, and is the only one by which it 
always differs from its near ally, L. terasensis, which is more sharp behind and usually 
obliquely truncate at the post-base. The two species have been continually con- 
founded, and even Dr. Lea has placed in his collection under the name parvus a 
number of specimens which I am sure are his texasensis. The former is generally the 
smaller of the two, though not always, as in northern Illinois it sometimes reaches 
alength of 2 inches. L. texasensis undoubtedly ranges north into northern Missouri, 
southern Illinois and Indiana, and the true parvus is occasionally found well down 
into Texas. 

’ This is often confounded with ZL. texasensis. It is a larger, thinner-shelled form, 
and is not so decidedly truncate at the post-basal region.

Warm Springs, North Carolina. 
Subgenus PROPTERA Rafinesque, 1819. 
(Type, Unio alatus Say.) 


Shell usually large, gaping at the anterior base and edge of dorsal 
slope, winged along the dorsal region when young and often when adult; 
beak sculpture feeble, consisting, when developed, of an anterior and 
posterior loop, the former often wanting; the latter sometimes becomes 
slightly nodulous; epidermis generally brown, often cloth-like when 
fresh, rayless or feeble EN teeth rather COMET PSETCOGE NET HES 


1Conrad’s an | is a poor one, and I can moh be positive just ahene the species 
should be placed, but incline to think it a member of the Texasensis group. Lea has 
a shell which he calls the pullus of Conrad, which came from Ravenel, labeled “‘S. 
Carolina,” but which, I think, is not this, but some species of the subrostratus group. 
It is quite probable that pullus is the same as Lea’s corvunculus.

frequently imperfect or nearly wanting; laterals remote; anterior muscle 
sears often complicated; dorsal scars consisting of a row of from four 
to thirty distinct, often deep impressions, running from the cavity of 
the beak obliquely downward anteriorly; nacre purplish. Animal 
with large branchiw; marsupium consisting of numerous, generally 
tine ovisaes, which are often somewhat radial: mantle thickened and 
distinctly double on the border, often papillose behind where the outer

teeth; anal opening smooth or only slightly crenulate. 


(Group of Lampsilis alatus.) 


Shell obovate, strongly winged, subsolid, with a slight posterior and 
superposterior ridge; epidermis thick, dark, showing irregular growth 
lines; hinge teeth generally well developed; nacre dark purple, female 
shell greatly developed in post-basal region. Animal with very numer- 
ous and fine ovisacs; marsupium large; inner gills united to abdominal

point than the type, and this form is common in the streams that drain into the Gulf 
east of the Mississippi, but it seems to connect with typical alatus in Tennessee. 

2A miserable, worn, young specimen of what I am quite sure is L. purpuratus. Lea 
states that the embryos of this are pouch-shaped, while those of purpuratus are wedge- 
shaped, but the form of embryos in a given species is often not constant.

1 There is only a single, young, poor specimen in the Lea collection, which may be 
a valid species, but is quite likely a L. purpuratus. 

2Only a single, dead, badly worn shell is in Lea’s collection. It is something like 
a young umbrosus, butif it really came from Tuscaloosa, Alabama, it probably belongs 
to the dlatus group. I can not decide certainly as to its affinities. 

3Mr. Lea states that a single specimen of U. saladoensis was collected by Dr. Ber- 
landier and presented to the Smithsonian Institution by Lieutenant Couch (Obs. 
VIII, p. 53). I have never found this shell, and have not seen the species, and am 
somewhat at a loss as to where to place it, but the figure and description would 
indicate that it 1s a young shell of a form related to purpuratus; its rays, which 
Dr. Lea says are nearest to U. amygdalum, being different from those of any related 
forms.

1The type of veracruzensis is in the Sana ean collection: and is undoubtedly a 
very young wmbrosus. 

2This species is extremely close to L. tampecoensis, and at one time I believed the 
two to be mere forms of the same thing. The present species is typically heavier 
and more inflated, as well as lighter colored, and has higher beaks than the latter. 
According to Hon. J. D. Mitchell, of Victoria, Texas, who has carefully studied these 
forms when living, berlandieri is more active, and while spawning it only buries 
itself sufficiently to he steady and give the post-ventral portion an elevation, while 
tampecoensis is sedentary in its habits, and buries itself entirely, excepting the 
extreme posterior point. Letter of Septemb.r 25, 1895.

1 Fischer and Crosse (see above citation) doubt whether Sowerby’s figures in Conch. 
Icon. and Kuster’s in Conch. Cab. are tampecoensis. ‘Though not very accurate figures, 
I can not refer them equally well to any other species. 

*Lea has two specimens of heermannii in his collection; the type, which is a young, 
slightly injured shell, and a very young one. Iam certain it is only tampecoensis. 

°Reeve described and figured this form in the Conchologia, supposing it to be the 
testudineus of Morelet, which is a very different thing. Fischer and Crosse in Mission 
Scientifique, believing it to be equal to Morelet’s erplicatus, placed it in the syn- 
onymy of that species. I have never seen an absolutely authentic specimen of expli- 
catus, but if Fischer and Crosse have accurately figured and described it, I am sure 
it is different from Reeve’s species, the latter being evidently more inflated, smoother, 
differently shaped, and having a great deal higher beaks. This being the case, it 
becomes necessary to give Reeve’s shell anew name. Fischer and Crosse credit the 
species to Sowerby, but the Plate xx11, in the Conchologia, is credited to Reeve. 

4A single valve of what is probably this species was received by the United 
States National Museum from Dr. H. von Ihering, under the name of Unio explicatus 
Morelet.

(Group of Lampsilis metallicus.) 


Shell rather small, obovate-rhomboid, inflated, much narrowed and 
rounded in front, the form approaching that of a Modiolus; epider- 
mis a rich coppery bronze, shining; beak sculpture consisting of two 
faint, rounded loops, the bars of which are inclined to be nodulous; 
pseudocardinals compressed, not well developed, and sometimes more 
or less broken into denticles; laterals distinct; pits in the beak cavity 
humerous and very irregular; nacre dark, coppery to purple, with 
metallic tints, iridescent behind. Animal unknown.

1T am considerably in doubt as to the relationship of the last two species. Fischer 
and Crosse are sure that alienigenus is close to wnbrosus, and their figure and descrip- 
tion seem to show that erplicatus is near to alienigenus. 

2The Transactions of the Philosophical Society, IV, in which Mr. Lea published 
his Unio cuprinus, which is identical with Mr. Say’s species, was issued, according to 
Scudder, in the latter end of 1831.

1The description of the plate is dated 1856, and in the contents it is credited to 
Reeve, although the previous plates bear date of 1865, and those following 1866. 

2Swainson’s Unio fragilis was published about the same time as Barues’s gracilis, 
and as it is impossible for me to say which has priority, I agree with Lea that it is 
better to adopt Barnes’s well-known name.

Shell compressed, thin, oblique, inequilateral, with a straight dorsal 
line which ends in a small wing in front and behind, rounded and cut 
away at the anterior base, produced in the post-basal region, gaping in 
front and behind, slightly twisted on its axis and usually bent poste- 
riorly to the right or left; a low, often double posterior ridge ends in 
a biangulate point behind; beaks compressed, the sculpture faint, irregu- 
lar, concentric ridges which continue over the shell, and at the beaks 
sometimes become rather sharply pustulous, the glochidium often 
remaining; epidermis yellowish brown, sometimes delicately rayed; 
teeth rudimentary, one or more faint compressed pseudocardinals and a 
single lateral in each valve; muscle scars irregular; nacre coppery or 
purple, often rayed. Animal unknown.

?The shells of this group bear a striking likeness to that of Unio tenuissimus Lea, 
in form, texture, color, teeth, and in gaping in front and behind, and I am inclined 
to believe that they are related to it, and the Unio myersianus of Southeastern Asia, 
to Unio alatus, and U. delphinulus of Central America.

Genus HYRIOPSIS Conrad, 1853. 
(Type, Unio delphinus Gruner.”) 
Hyriopsis CONRAD. Pr. Ac. N. Sei. Phila., 1853, p. 269. 


Shell large, compressed, rhomboid-eiliptical, dorsally winged and gen- 
erally biangulate behind, sometimes produced in the post-basal region; 
beaks low, mostly compressed, the sculpture consisting of numerous 
concentric ridges nearly parallel with the growth lines, generally 
extending well on to the disk of the shell, the earlier ones fine, often 
slightly nodulous or doubly looped; epidermis olive to brown, some- 
times faintly rayed; pseudocardinals two or three in the left valve, one 
to three in the right, when young compressed, but often breaking into 
irregular denticles when old; laterals long, compressed, two in the left 
valve and one in the right, sometimes vertically striate, the left valve 
often having a sort of raised lamellar tooth at or just behind the-beak. 


' Said to be of Jonbertin the literature. 

2The general make-up of the shells of this genus, Cyclomya, and Cristaria seems to 
indicate close relationship to each other, and a not distant one to the subgenus 
Proptera of Lampsilis, and | should not be surprised to learn that the marsupium 
occupies the posterior part of the outer gills in distinctly marked ovisacs,

Beak cavities shallow; dorsal scars numerous, extending from the cav- 

ity downward and forward. Anterior muscle scars three, distinct, pos- 

terior large, indistinct; front end of the sheli usually thickened; a row 

of plications often occurring just below the laterals, as in Cristaria. 
Animal unknown. 


(Group of Hyriopsis bialatus.) 


Shell somewhat trapezoidal, with a posterior ridge, biangulate behind, 
with a very high, pointed, triangular, posterior wing, and a smaller, 
pointed one in front, which projects forward; beaks low, sculpture not 
seen; epidermis brown; pseudocardinals broken up into denticles; 
hinge line slightly curved; the three anterior muscle scars separate and 
deep; dorsal scars not extending greatly downward in front; nacre 
bluish white.

'The ventral line of this shell is crooked, having a couple of curves in it, but it is 
not twisted. Its authors believed Arconaia to be only a section of Unio, and that 
the animal was essentially like that of that genus. 

2>Sowerby published this species as Unio subtrigonus in the Conchologia, the name 
being preoccupied by Deshayes. In the errata he changed it to Unio (Monocondy- 
lea) cambojensis, believing it to be the same as Petit’s Psewdodon cambojensis. It 
certainly is not that shell, and I agree with Fischer that it is near to the Unio myer- 
sianus, and accept his name for it,

ing it.

Lepidodesma SIMPSON, Proc. U.S. Nat. Mus., 1896, p. 311. 


Shell large, thin, inflated, with a high, sharp, posterior ridge and a 
second fainter one above, making the hinder part widely biangulate; 
beaks very high and full, their sculpture, which extends over the whole 
shell, consisting of ridges that follow the growth lines; there are two 
rows of radiating nodules, one on the middle of the disk, and a stronger 
one on the post ridge; ligament very large, wide, covered with con- 
centric scales; hinge line arched; two pseudocardinals in the left valve, 
the anterior elongated, running inwardly across the hinge plate, and 
ending abruptly, with a shorter, fainter one behind it; with two strong 
laterals, the inner the higher, its edge reflexed upward, and suddenly 


better developed than is common among Cristarias, but are still quite faint. 
2>Heude has figured two different species under the name of Dipsas parrulus, on 
plate xxxu. Ihave therefore given the last-described form the name radiata.

here is a specimen of Pilsbryoconcha in the Philadelphia Academy which agrees 
perfectly with Conrad’s description, and is probably the type. My attention was 
called to this by Mr. Pilsbry, who believes this to be the shell Conrad described. It 
is rather a small species. 

2An old, elongated, rather peculiar shell. Conrad’s species may be the young of 
it, and Morelet believes that Martens’ 4. schomburgki is very close to his shell I 
have not seen a sufficient amount of material of this genus to determine with cer- 
tainty whether all these are valid species.

portion of the shell plicately or nodulously wrinkled; epidermis smooth 
and bright, variegated with broken green rays and blotches; beak sculp- 
ture consisting of rather fine, subparallel, often broken ridges in two 
loops, the anterior rounded, the posterior somewhat angled, occasion- 
ally broken up into zigzags;' pseudocardinals small, stumpy and some- 
what roughened; laterals rather short, slightly curved and club-shaped, 
remote; dorsal cicatrices few, placed under the hinge just behind the 
_ beaks; anterior cicatrices rather deep; posterior cicatrices rounded, 
large, and well impressed; anterior part of shell somewhat thickened; 
female shell slightly swollen just behind the middle of the base. 

Animal with the inner gills wholly or in part free from the abdominal 
sac; marsupium occupying the central posterior part of the outer gills, 
sometimes extending nearly thei whole length, consisting of few to 
many rather large, irregular ovisacs, which are not so distinctly 
marked out as in Lampsilis, but which have rounded bases; mantle 
much thickened on its lower edge, which is dark colored and sometimes 
papillous. 


(Group of Medionidus conradicus.) 


Shell small, usually with a well-defined posterior ridge; posterior end 
and sometimes the greater part of the shell slightly wrinkled or nodu- 
lous; epidermis rather smooth, painted with rays broken into irregular 
arrow-head markings or blotches; pseudocardinals rather small and 
imperfectly developed; laterals of left valve separated by a narrow, 
shallow furrow; nacre greenish, purplish, or bluish. The male shell is 
often decidedly arcuate; that of the female is swollen at or behind the 
center of the base. Animal having the characters of the genus.

species was never figured, and his description does not just agree with Lea’s species. 
As the type is not known to be in existence I think under the circumstances, since 
we can not be sure of what Say described, it is best to use Lea’s name. 

2 The type which is in the collection of the U. S. National Museum is, without 
doubt, a young medellinus.

full, sculpture feeble, consisting of slightly outlined ridges, somewhat 
doubly looped, the looped lines becoming swollen or nodulous at their

1T have only seen two specimens of Lea’s Unio averyi and one of his U. caldwellii, 
and I can not be certain as to their systematic position. In the latter the beak 
sculpture, which is slightly worn, is much of the character of the species of Neph- 
ronaias generally, and not like that of Unio, and though somewhat worn the shell 
shows traces on the posterior end of faint, bluish green rays. One of the former is 
Slightly more inflated in the post-basal region than the other.

Isthmus of Tehuantepec, Oaxaca, Mexico; Honduras. 
(Group of Nephronaias reticulatus.) 


Shell evenly elliptical, shightly biangulate behind, solid and inflated ; 
surface covered with fine, concentric ridges and having delicate, radiat- 
ing furrows which cut the sulcations and form them into loops. 


1I formerly believed that this species, with the one preceding and following it, 
ran together. More recent study, with a large amount of additional material, 
inclines me to think that perhaps they may be valid species. Under the name of 
Unio rowellit Mr. Lea has in his collection two large N. macneilii, one large rowellii, 
three smaller ones and several valves, and two goascoranensis, a species which is 
very close to the rest, but probably as good as most of the Mexican forms. I find 
specimens which I can scarcely refer with certainty to macnielii or oregonensis, but 
which seem to have to some extent the characters of both. This, with a number of 
the Mexican and Central American forms, is exceedingly puzzling. This species 
occurs with N, rowellii and macnielii,

'Lea and Poey regard this as the equivalent of N. scamnatus of Morelet, while 
Arango believes it to be distinct. Unfortunately both species were described in 
Latin and not figured, but Dunker states that his species is inflated posteriorly and 
has a bluish nacre, and it is probable that he had before him a female shell when he 
wrote the description, for one of the Cuban species, which I think is gundlachi, 
has a bluish nacre, and the female shell is decidedly swollen at the post-basal region. 
In another form, which I presume is N. scamnatus of Morelet, the nacre is rather 
dark, the shell somewhat elongated, and that of the female does not greatly differ 
from the male. 

2T am not positive that this species belongs here, but its form is like that of most 
of the members of the genus, and Crosse and Fischer state that the beaks in their 
specimen are entire and smooth. In several of the species of this genus the beak 
sculpture is very faint, while in Unio itis almost always strong. These considerations 
lead me to place the species here,

1Probably a mere variety of wruginosus. 

2XKuster credits this species to Australia and says that it has a purple nacre. The 
nacre of all the Australian species is whitish, and the shell is evidently a member of 
this group. 

3This and the related species are extremely puzzling. Although I have been able 
to examine a good deal of material, yet I find great variation in the specimens, and 
few of them acurately agree with the figures and descriptions. 

4Fischer and Crosse believe this to be Morelet’s species. It looks like a short 
cuprinus, but Sowerby says it is solid, and has a dirty-white nacre, while cuprinus 
is rather thin and is copper colored throughout. 

5The specimens which I have seen do not wholly agree with Kuster’s figure and 
description, but are nearer to that than anything else. The material in the U.S. 
National Museum is mostly from Honduras though there are specimens credited to 
Cuba. Lea referred these to NV. scamnatus Morelet.

Shell solid, much inflated, short elliptical, bluntly pointed and slightly 
biangulate behind, with a low, posterior ridge; female shell swollen at 
post base; beaks compressed, the sculpture not seen; epidermis brown- 
ish, clothlike; pseudocardinals divided into irregularly radiating, gran- 
ular lamina, sometimes to the number of a dozen or more in each valve; 
hinge plate reduced to a mere rounded line behind the pseudocardi- 
nals; laterals short, remote, anterior adductor scars deep, smooth; 
there is in each valve only a single, large, semicircular posterior scar 


‘Tam not certain just where this and the preceding species should be placed. 
This remark can be applied to a number of other forms placed in this genus. 

27 have examined a number of animals of the only species of this curious genus, 
but regret that they were badly decayed, and that none were gravid. In one speci- 
men several ovisacs were distended with gas, and these were separated by a deep 
sulcus. This fact, the union of the inner gills with the abdominal sac, and the post- 
basal swelling seen on some shells incline me to believe that it is a highly organized 
species.

with a straight edge in front; dorsal scars numerous, distinct, placed 
back of the pseudocardinals; cavity of the beaks not deep or com- 
pressed; nacre dull lurid to purplish brown. 

Animal with gills nearly equal in size, inner slightly the larger in front,

1Conrad says itis suboval, with the disks somewhat flattened, with minute, radiat- 
ing lines extending to the tips of the beaks. The rotundata sometimes shows radi- 
ating ridges at the beaks in eroded specimens. He also states that the nacre of his 
species is purple. The description therefore fits Lamarck’s species perfectly, 
though I have never known the species to come from so far west asthe Rio Grande— 
Conrad’s locality.

valis) is, and the second (0. torsa) is either the Unio retusa of Lamarck or a variety 
of Lea’s U. circulus with purple nacre, I can not be certain which- Which of these 
two nearly related species it may be, I consider it sufficient to establish the genus, 
his description being applicable.

1 The figured type has a purple nacre. 

2 Ferussac makes this = U. orbiculatus Hildreth also. 

2 This is sometimes considered asynonym of O. circulus. The two species are exces- 
sively variable in form, and both often have a pink or purplish nacre. While indi- 
viduals may occasionally be found which can only be referred to either species with 
doubt, the majority of specimens can readily be determined, and Dr. V. Sterki 
informs me that he has found differences in the animals of the two. As I have only 
been able to examine the soft parts of young specimens I have not detected any 
differential characters in them.

Kseambia River, Escambia County, Florida. 


Subgenus PSEUDOON Simpson, 1900. 
(Type, Unio ellipsis Lea.) 


Shell elliptical, inflated, solid, that of the males slightly pointed at 
the upper posterior part; epidermis brownish or blackish, rayless or 
very feebly rayed, beaks anterior; pseudocardinals solid, stumpy, or 
slightly elongate in age, and showing a tendency toward being parallel 
with the laterals; cicatrices deep; nacre silvery, iridescent posteriorly. 

Animal with mantle having a wide, thickened, double border, the 
inner edge being toothed throughout below; gills small; marsupium 
not reaching to the posterior end of the outer branchiz, though extend- 
ing quite well forward; ovisacs rather numerous, large and distinct, 
tinted with purple below; anal and branchial openings finely toothed. 


1The type is a young female, somewhat broken, and besides this Lea has a shell 
which he has so named that I believe is O. castaneus. Under the name of Unio lens 
(Cat. No. 85743, U.S.N.M.) he has a young shell from Jackson, Mississippi, which is 
a young male unicolor. The species grows to the size of O. lens, but shows dull rays 
and is more inflated than that species. 

2 Dr. Lea states that the type is from Erie County, Michigan. There is no county 
of that name in the State, and his specimens may be from Erie County, Ohio. I am 
very doubtful whether it is more than a dwarf variety of U. circulus, as specimens have 
been seen from Tennessee which seem to stand between the two forms.

1The name castaneus was applied to some Unio which I am unable to determine, 
by Rafinesque in a continuation of a monograph on the Bivalve Shells of the River 
Ohio, etc., in October, 1831. According to Scudder, Lea’s name was published the 
latter part of the same year, but I have no means of knowing which appeared first. 
Under the circumstances I use Lea’s name.

Shell triangular ovate, somewhat inflated, solid, with a distinet and 
often sharp posterior ridge; surface concentrically sculptured; umbonal 
area Somewhat flattened; beaks high, sculptured with delicate, parallel, 
doubly looped ridges, the anterior loop rounded, the posterior angular ;

curved; cavity of the beaks moderate, often somewhat compressed; 
nacre silvery; female shell more or less inflated at postbasal region. 

Animal with the outer gills narrow in front, wide behind; inner gills 
wide in front, posteriorly free or united to abdominal sac; marsupium 
occupying the posterior part of the outer gills, but not extending quite 
to the hinder end, consisting of well-marked ovisaecs which are rounded 
below; a distinct sulcus extends the whole length of the kidney-shaped 
marsupium at the inside and outside at some distance above its base; 
mantle edge thickened and somewhat doubled, in some cases toothed or 
fringed below. 

'. Subgenus PLAGIOLA (Rafinesque, 1819) Agassiz. 


Shell solid, surface irregularly concentrically ridged; epidermis 
smoothish, but here and there wrinkled; painted with larger and 
smaller scattered rays, which are generally broken into irregular lunate 
or squarish blotches; hinge heavy and strong; hinge plate wide and flat; 
female shell smaller than the male, more inflated, and swollen at post- 
basal region. e 

Animal with the branchie rounded below, inner the larger, wholly or 
partly free from the abdominal sac; marsupium large, projecting far 
below the inner gills; mantle very thin, dark on its thickened, fringed 
double edge; anal opening with very small papille.

' Rafinesque’s name depressa, for what is probably a male of this species, has prece- 
dence over Lea’s name, but it was used previously by Lamarck for an Australian 
Unio. Rafinesque placed this species in his genus Obliquaria and the subgenus 
Plagiola, but after giving the name Obliquaria depressa he calls it U. depressa in paren- 
thesis.

with a beautiful pattern of broken or arrow-marked rays; area of the 
beaks flattened off in the direction of the axis of the shell, but not 
compressed; beak sculpture delicate, somewhat broken and doubly 
looped, the anterior loop rounded, the posterior sharp below, the ribs 
fading out where they cross the posterior ridge; hinge delicate, pseudo- 
cardinals rather compressed, high, and ragged; hinge plate narrow; 
female shell very slightly swollen at post base. 

Animal with branchize more or less free from the abdominal sac; mar-

Subgenus PIYCHODERMA Simpson, 1900. 
(Type, Unio cyrenoides Philippi. ) 


Shell triangularly ovate or rounded, solid, bluntly angled before, 
more sharply angular behind, with a tolerably well-marked posterior 
ridge; surface strongly and irregularly concentrically sulcate; beaks 
small but rather prominent, sculptured with fine, irregular, broken 
ridges, which are somewhat doubly looped, the front loop being larger 
and more rounded; epidermis olive to tawny, wrinkled, sometimes 
having faint rays; pseudocardinals compressed, ragged; hinge plate 
narrow; laterals short, slightly curved, obliquely striated; muscle 
sears rather shallow, the posterior round; female shell produced in 
post-basal region. 

Animal with small branchie, inner united the whole length to the ab- 
dominal sac, wider than the outer in front, narrower behind; marsupium 
occupying the posterior part of the outer gills in from eleven to twenty 
distinct ovisacs which are rounded and dark below, the whole having 
a decided, parallel sulcus inside and out near its base; mantle thin, 
papery, with a wide, thickened, double edge, which is sometimes cre- 
nate; branchial opening large fringed; anal opening smooth or with 
only the faintest crenulations.' 


(Group of Plagiola cyrenoides.) 


Shell generally more or less covered with radiating grooves which cut 
up the concentric sculpture into looped wrinkles or nodules, sometimes 
having the appearance of dried, wrinkled paint, the sculpture extend- 
ing into the substance of the shell; epidermis usually tawny or yel- 
lowish, rarely showing any vestiges of rays; female shell greatly pro- 
duced in the post-basal region.

inside of the marsupium was quite deep, in fact the part above it hung over it in a 
sort of flap, which would no doubt disappear if it was filled with ova,

1] have never seen a specimen among the hundreds examined that had young or 
ova in the gills. But I have seen spermatozoa in specimens with inflated shells and 
ova in those with the wing. Mr. H. M. Kelly, of Mount Vernon, Iowa, who has made 
a very careful study of the anatomy of many of our Unionide, assures me that the 
form with the compressed shell, having the expanded flap behind, is the female. 

21t has been claimed that this species was previously described nnder the name of 
Obliquaria verrucosa by Rafinesque, but I am unable to make anything out of his 
figure or description; hence I use the name given by Barnes. Barnes’s name was 
used by Rafinesque for the species which the former called Unio verrucosus, but as 
Rafinesque placed his species in Obliquaria, and as the generic names of both forms 
are changed in this work, I do not consider Barnes’s name preoccupied. 

3] think that this is a large, rather high male of the species in question. I can not 
tind any description of Unio gigas by Swainson, to whom Sowerby credits this species, 
and the Megadomus gigas of Swainson (which, so far as I know, is undescribed) can 
not be it, as the latter says that his genus, Megadomus, has the lateral teeth imperfect, 
one or none. Treatise on Mal., p. 266.

1T am sorry to have to place the very appropriate and well-known name of Barnes 
in the synonymy, but Ii believe that the description of Rafinesque for his Obliquaria 
refleca defines this species and nothing else, and although it is not figured, I feel jus- 
tified in using it. 

2 A singular shell having the general form of reflexa, but the knobs are much 
broken up. Ihave seen specimens which agree quite well with Conrad’s fine figure, 
which I have no doubt represents an unusual form of Rafinesque’s species, and they 
hardly seem to me to be a varity. I do not think the so-called type in the Phila- 
delphia Academy of Natural Sciences is valid.

2Typically this form is quite distinct from the ordinary manifestation of the spe- 
cies, being very solid and much humped, but there seems to be every possible varia- 
tion to the lighter, more compressed forms, and I do not think it is worthy of a 
varietal name.

Alabama River drainage. 


1 The type is simply an old, stunted phaseolus, with nearly every vestige of epider- 
mis eroded away. 

2This is the name originally given by Dr. Lea. He afterward changed it to 
woodwardianus. 

3T formerly thought foremanianus and woodwardianus distinct, but alarge amount of 
material received from Mr. R. E. Call, from the Cahawba River, Alabama, shows 
that the two absolutely blend together, there being a great diversity of form, and 
some specimens show the capillary rays of foremanianus and the square spots of 
woodwardianus, while others are of a uniform tawny color.

irregular concentric ridges; epidermis beautifully painted by undulated, 
radiating, broken hair lines or fine maculations; hinge plate wide and 
flat; pseudocardinals triangular, small and low, ragged; laterals low, 
short, club-shaped; cavity of the beaks deep and compressed, dorsal 
muscle scars on the under side of the hinge shelf; adductor scars small; 
front part of the shell very thick, suddenly becoming thinner at the row 
of humps; male and female shells much alike. 

Animal with the inner branchie much the larger, curved below, free 
from the abdominal sac; marsupium occupying the base of nearly the 
whole outer branchiz in numerous rather indistinctly marked ovisacs, 
bases of the ovisacs slightly rounded; ova very minute; palpi small, 
curved; branchial opening very large, extending one-third of the way 
along the base, fringed with many brown papille; anal opening very 
large, finely crenulated.

DIAGEN 2. 


Male and female shells alike; embryos contained in the outer gills in 
short ovisacs which run crosswise of the branchi, and are discharved 
entire into the water. 


1 Generally this form is more compressed and less humped than D. dromus, but I 
think it is probably only a variety of the latter. 

2? Haldeman only gave a brief description of his species, and it has never been 
figured. According to Lea it equals his U. caperatus, and I believe he is correct.

consisting of short, horizontal ovisacs which run directly across the 
gills, and are discharged through the outer wall with the ovules in 
them; ovules ten to twenty-five in each ovisac, in one or two rows; inner 
gills the larger, free in part from the abdominal sac, or wholly united; 
mantle generally bordered behind with square, black spots; branchial

1Much confusion exists concerning this and the preceding species. The edentulus is 
much the larger and solider shell; the undulatus being a small, thin form (Say’s figure 
is only about half an inch long, from a young or very dwarf specimen), usually quite 
distinctly biangulate behind. The latter is confined tothe Atlantic drainage, while 
the former is found in this area and in the Mississippi Valley.

1The number of specific names bestowed on the Anodontas of Kurope must run up 
into the thousands. I have gone over the literature as carefully as possible, and 
large series of specimens from many localities, and I confess that I am absolutely 
unable to separate these forms specifically. The variations of form, size, color, 
solidity, and even texture are sufficient for a large number of species if they were 
not everywhere connected by intermediate examples. The new school of concholo- 
gists has named every conceivable variation, and in very many cases distorted 
individuals. Europe is a densely settled region, and it is possible that the waters 
of the streams and ponds in many places may be so affected by sewage and other 
offal as to produce many changes in the mollusks living in them. I shall attempt 
to recognize a few of the leading forms as varieties, referring them to the author 
originally describing them, but on account of the enormous amount of literature 
pertaining to these forms and its confused condition, I can not attempt to trace out 
these varieties among the descriptions of subsequent writers. 

2According to Hanley (Shells of Linnzeus, p. 144) the A. cygnea var cellensis of 
Rossmassler (Icon., 1V, 1830, pl. x1x, fig. 280) is marked for this in the Linnzan cab- 
inet. Itisa large, rather elongated shell, slightly biangulate behind, somewhat 
cut away on the upper posterior part, and having fairly full beaks.

%Probably a valid species, yet some specimens apparently belonging to it are cer- 
tainly very much like forms of cygnea.

1 Sowerby states that his species is from Lao, (Laos?) an error without doubt, as itis

Kokeil (or Rossmassler) Fischer changed Sowerby’s name to laosensis.

Mexico, mostly in the Pacific drainage. 
(Group of Anodonta dejecta.) 


Shell rather solid, subtrapezoidal, narrower and rounded in front, 
where it is often considerably thickened, with a slight post-dorsal wing; 
beaks rather compressed, the sculpture consisting of numerous irregu- 
lar ridges which have a tendency to become doubly looped and nodu- 
lous; epidermis rather smooth and shining, greenish or ashy brown; 
nacre lurid, darker in the cavity of the beaks; muscle scars irregular, 
not well defined; dorsal scars few and rather deep. 

Animal with dark colored branchiz, the inner wider in front, nearly 
or quite free from the abdominal sac, the outer wrinkled on the outside 
into longitudinal and vertical folds, all four united to the mantle to 
the extreme posterior end; palpi very large; mantle with a wide, thick- 
ened double edge; branchial opening with numerous papille; anal 
opening smooth; superanal opening long, deep, united a long way below.

Shell thin or solid, inflated, rather evenly rounded in front, generally 
somewhat biangulate behind, and very slightly winged in the post- 


1Said to be from Arkansas River or its tributaries west of the one hundredth 
meridian and collected by Dr. H. C. Yarrow, surgeon and naturalist of Wheeler’s 
expedition. This locality is erroneous, as it belongs, no doubt, exclusively to the 
Pacific drainage.

dorsal region; beaks rather full, the sculpture consisting of a moderate 
number of concentric ridges or corrugations, which are generally some- 
what doubly looped, and often slightly nodulous; epidermis bright and 
shining, sometimes faintly rayed. 

Animal with large branchiz, the inner larger in front, free in part 
from the abdominal sac; marsupium occupying the entire outer gills, 
forming an enormously thick, liver-colored pad when filled; mantle thin, 
thickened on its edge; branchial papillz small; anal opening smooth.

1 This species is probably better known by Dillwyn’s name, fluviatilis. According 
to Lea and Binney, the first edition of Nicholson’s Encyclopedia appeared in 1816, 
which would give Say’s name priority by one year. This edition is extremely rare, 
and I have never seen it. It is claimed by some authors to have been issued in 1817. 
Dillwyn refers his species to Gmelin, who states that his shell came from the fresh 
waters of Europe, and is allied to anatina, and it is quite likely it is A. cygnea. As 
there can be no doubt about Say’s species, I think it best to use his name. 


21 think this is merely a southern form of cataracta and scarcely worthy of a 
varietal name.

1T am very sure hae this=the 4. fragilis ‘Denna and not the vente Dire, 
as Dr. Lea believes. Say describes it as very thin and fragile; epidermis green 
olive, paler on the disk, and greener before (behind), within ier white, edged 
with whitish, and from his dimensions and figure it is a smaller shell than Dillwyw’s, 
the whole agreeing better with the fragilis of Lamarck.

1The type of this is in Mr. Bryant Walker’s collection, and seems to be a variety 
of marginata. 

2It is hard to say where this belongs, or what it is. The figure shows it a dirty 
yellowish, without rays, and shaped something like 4. fragilis, while the description 
is too brief to properly characterize it. 

’This may be 4. grandis Say. 

4T am not certain whether this is the implicata of Say or his cataracta. De Kay 
states that the shell is thin and fragile, and the figure shows it to be brown, green, 
and yellowish, in irregular bands, and apparently shining and smooth like cataracta. 
He says that it is nearest to implicata.

Group of Anodonta imbecillis. 


Shell thin, elliptical, sometimes slightly produced near the center of 
the base, pointed behind, with a slight posterior dorsal wing; area of 
the beaks generally flattened though often full; beak sculpture con- 
sisting of several rather delicate, irregular ridges which show a tend- 
ency to break into nodules; epidermis brightand smooth, usually marked 


1The type of A. hallenbeckii is a suleate shell, somewhat constricted at the central 
base, while that of A. gesneri is not constricted and is smoother. The former may be 
slightly diseased, and the museum series of shells appears to absolutely connect the 
two. 

2 First spelled dolearis by Lea, and afterwards changed by him to doliaris.

'Typically very distinct from imbecillis, having the dorsal and basal lines quite 
straight. But there are many intermediate forins which are very hard to place, and 
it is probably only a variety of the latter.

3An exceedingly variable species in form, size, and solidity. 4. dunlapiana seems 
to me to be only a slightly elongated, rather solid form.

South Carolina to Florida. 
(Group of Anodonta suborbiculata.) 


Shell large, compressed, suborbicular, somewhat produced near the 
center of the base, rounded in front and bluntly pointed behind, with a 
slight posterior dorsal wing; beaks flattened, the sculpture consisting 
of a few irregular ridges, which are generally broken into nodules, 
sometimes only corrugated; a well-defined but low posterior ridge sepa- 
rates the smooth, shining area in front from a darker and rougher one 
behind; epidermis with numerous delicate, capillary rays near the 
beaks; muscle scars very large; nacre rather coppery and iridescent; 
palleal line broken, often marked with radiating ridges. Animal 
unknown. '

(Group of Anodonta woodiana.)' 


Shell oval, inflated, sometimes narrowed in front, pointed behind, 
and often a little produced at the posterior base, slightly winged in the 
post-dorsal region; beaks full, sculptured with numerous strong con- 
centric ridges, which are either straight in the center of the disk or 
slightly doubly looped. There is often a faint posterior ridge, which 
may be double, making the shell feebly biangulate behind; dorsal 
scars one or two under the beaks; muscle scars irregular. 

Animal with the gills large, equal in size, rounded below, free the 
greater part of their length from the abdominal sac, somewhat 
wrinkled; marsupium occupying the entire outer gills, forming thick 
brown pads when filled; palpi large, subelliptical, free from the mantle 
a long way; mantle having a wide, thickened edge; branchial opening 
crowded with dark papilla; anal opening with no papille, but having 
purple ridgesinside; superanal opening closed nearly its whole length.’

1 Fischer has made a subgenus Pteranodon (Man. Conch., p. 1003) for A. magnifica, 
but I do not see any need of giving it and the related species any higher rank 
than that of a group. The shell and animal differ but little from those of other 
Anodontas.__ . 

2A group closely agreeing in general characters, but having enormous individual 
variation. Pere Heude has bestowed specific names on a great number of forms, 
most of which are, I think, merely mutations of Lea’s woodiana. Fortunately the 
U. 8. National Museum possesses in the Morelet collection a large series of author’s 
specimens, and the excellent figures in the Conchyliologie Fluviatile Nanking 
enable me to straighten out this difficult group to some extent. 

3 Larger and rather more finely developed than A. woodiana, but the large series 
of material J have examined absolutely connects the two.

1A species having a very wide distribution and abundant in individuals. It is an 
exceedingly variable form, and a large number of names have been bestowed on its 
mutations, all of which seem to be closely connected. I have retained some of these 
in a varietal sense.

1T have seen Say’s type of 4. grandis, and it appears to be identical with Lea’s 
ovata. 

2This is an ovata which had become diseased internally, probably from the work 
of a Trematod, so that the nacre became roughened or blistered, and generally sal- 
mon colored. S

1A variety of grandis. The type is a large, heavy form, with a considerably 
developed posterior ridge, the shell somewhat truncated above and behind the ridge. 
I have frequently seen such shells which are evidently pathologic.

-1T am wholly unacquainted with this genus. All the species are from the Danube, 
and if the characters are accurately given it may possibly be a valid genus, though 
Westerlund gives it subgeneric rank under Anodonta. It is more than likely, how- 
ever, that all the so-called species are merely specimens of the well-known Anodonta 
cygnea, having a dorsal wing which conceals the ligament, and something which 
may be vestiges of lateral teeth. Such examples occur among Anodontas in other 
parts of the world.

1Locard described this as a Pseudodon, and previously in the same year described 
a Leguminaia chantrei, which seems to me to be a mere variety of L. mardinensis. As 
both are undoubtedly Leguminaias, and as the present species was the last described, 
I am compelled to change its name. 

?Lamarck’s brief description of Anodonta uniopsis entirely agrees with the shell 
commonly known as Microcondylwa or Monocondylewa bonelli. The statement that the 
ligament passes into the hinge exactly fits this, and this is one of the best generic 
characters of Leguminaia. 

>The amount of variation of this species is very great. In many cases the poste- 
rior end has evidently been injured by unfavorable environment, and the shell is 
dwarfed and variously distorted, and sometimes a good deal thickened. Of course 
every individual variation and distortion of this kind has been seized on by the New 
School and elevated to specific rank. I have seen only what seemed to me a single 
species of this subgenus, and nothing which really was worthy of a varietal name.

5Credited by Rossmiissler to Ferussac, but without other reference. Lea says 
Ferussac’s manuscript labels, neither of which constitutes a published description.

Shell elongated, subsolid, inequilatural, generally wider in front, 
rounded-truncate at anterior base, pointed at post-basal region, and 
having a low posterior ridge, with one or more secondary ridges above 
it; beaks low, sculpture consisting of a few coarse, irregular, longi- 
tudinal folds; epidermis shining, often rayed; a single imperfect tooth 
occurs in each valve, and sometimes vestiges of laterals; there is one 
roughened dorsal scar in the shallow beak cavity; muscle sears very 
large, deep and distinct, the posterior greatly elongated; nacre pur- 
plish, shading to blue at the edge; palleal line radially ridged. 

Animal with very long branchiz, inner and outer about alike in size 
and form, projecting free slightly behind, the inner free from the abdom- 
inal sac nearly the whole length, brownish throughout; palpi long, 
large; mantle thickened at edge, brown, black above; branchial opening 
large, with heavy papille; anal opening large, without papillz; super- 
anal opening united below; foot very large when living, club-shaped, 
capable of great extension. No gravid specimens have been seen, but 
the outer branchiz are probably used as a marsupium.

Genus SOLENAIA Conrad, 1868. 
(Type, Mycetopus emarginatus Lea.) 
Solenaia CoNRAD, Am. Jl. Conch., IV, 1869, p. 249. 


Shell greatly elongated, falcate, rather thin, narrower and rounded 
in front, the upper anterior portion being strongly sulcate, gaping at 
anterior base and behind, having a strong posterior ridge that ends in 
a point at the post base; beaks low; sculpture of slightly double-looped 
concentric ridges; epidermis rayless; hinge line narrow; teeth rudi- 
mentary, being mere vestiges of one or more lamellar laterals in each — 
valve; dorsal scars numerous, in a line under the hinge; anterior scars 
faint; posterior elongated; palleal line with a distinct posterior sinus. 

According to Fischer the foot is enormously developed for the purpose 
of burrowing, asin Mycetopoda. Itis probable that the mantle is closed 
behind into two siphons. 


(Group of Solenaia emarginata.) 


Anterior region much narrowed, drawn out in the direction of the

1Said to come from forest streams near Chyavetas, Upper Amazon, and to have 
been discovered by Mr. Bartlett. I can not believe that it is a South American 
species at all, but rather that it is from southeastern Asia, as it is an almost exact 
miniature copy of S. emarginatus Lea from that region, having its texture, and not 
the suft, shining appearance of the Mycetopodas. It was described with a miscella- 
neous lot of shells from various localities, and that given for this is, I think, 
erroneous.

I have observed. It differs from Anodonta in the curving in of the hinge line in 
front of the beaks, in the beak sculpture, and in having papille on the anal open- 
ing. Notwithstanding the fact that I have found embryos in all four gills of a 
specimen of this genus, I have placed it with the Homogen:e rather than with the 
Tetragenz because the characters of shell and animal seem to agree better with the 
former than with the latter.

Genus PEGIAS Simpson, 1900. 
(Type, Margaritana fabula Lea.) 


Shell small, thickened in front, with a sharp posterior ridge, in front 
of which is a wide radial depression, ending in a basal sinus; above 
this ridge is another, making the shell decidedly biangulate and trun- 
eate behind; beak sculpture consisting of subconcentric corrugations, 
generally swollen on the posterior ridge; epidermis decorticated, but 
showing a few dark, radial rays on the base of the shell; pseudocardi- 
nals rather solid; laterals wanting. Animal having the marsupium 
empty in the specimen examined; inner gills larger in front, free from 
the abdominal sae, all four truncated behind; palpi large; mantle with 
square spots on its edge; branchial opening with a few large papille; 
anal opening smooth, not separated from the superanal.

Genus ARCIDENS Simpson, 1900. 
(Type, Alasmodonta confragosa Say.) 


Shell subsolid, inflated, subrhomboid, with full, high beaks; beak 
sculpture very strong, consisting of irregular corrugations which fall into 
two loops, at the bases of which the ridges are swollen into knobs that 
continue out in two radiating rows on to the disk of the shell; in front 
of and behind the beaks are many fine, radial wrinkles, the posterior 
ones being zigzagged; surface of the shell covered with oblique folds 
and wrinkles; epidermis dark olive, shining; there are two elongated, 
compressed psuedocardinals in the left valve, the posterior under the 
beak, and curved upward, cutting off the hinge plate in the right valve, 
which has a single, compressed pseudocardinal in front; laterals numer- 
ous, short, blurred; muscle scars irregular; nacre white. Animal with the 
gills very large, rounded below; inner the larger, free from the abdominal 
sac; marsupium filling the outer gills, of a peculiar, granular texture; 
palpi very large, elongated, attached half way to the mantle; mantle 
with a thick, unspotted border; branchial opening large, papillose; 
anal opening with rudimentary papille.! 


‘In the only gravid specimen I have seen the marsupium presented a peculiar, 
striated, granular structure, different from that of any Naiad I know. It was nar- 
rowed in the middle, and produced into a sort of lobe behind, but, though the spec- 
imen seemed to be a perfectly normal one, I am in doubt whether this peculiar form 
is constant. I do not think that this granulation is the result of a diseased condi- 
tion, though it may be.

1 Lea changed his name compressa to pressus because the former had been used for 
a Unio previously by Sowerby. The restoration of the genus Symphynota makes the 
earlier name of Lea valid. 

2Credited by Conrad and others to Rafinesque. The description of the latter of 
Unio viridis is not sufficiently clear to distinguish it from some of the other members 
of this genus, and the locality given is in error for the shell figured by Conrad, 
which belongs exclusively to the Atlantic drainage, and not to the Ohio River and 
Kentucky, localities given by Rafinesque. .

Subgenus LASMIGONA Rafinesque, 1831. 


(Type, Alasmidonta costata Rafinesque. )! 


Shell subrhomboid, compressed, corrugated behind; beaks low, their 
sculpture consisting of several coarse ridges which generally fall into 
two slight loops, and often with radiating ridges in front and behind; 
epidermis shining; laterals partly developed, consisting of blurred ridges 
which slope diagonally downward and backward on the hinge plate; 
cavities of the beaks shallow; dorsal scars faint, irregular. 


'The description of Alasmidonta costata of Rafinesque so clearly covers the species 
described three years later as Alasmodonta rugosa by Barnes that the former name 
must be used. 


NO. 1205. SYNOPSIS OF THE NAIA DES—SIMPSON. 665 


Animal with the marsupium occupying the whole of the outer gills, 
very thick, like that of Anodonta; inner gills free all or the greater part 
of their length from the abdominal sac; branchial opening papillose; 
anal opening generally smooth or only slightly crenulate.

'Say’smanuscript. I believe this to be specifically different from the Seog thin- 
ner, less inflated, biangulate 4. marginata. The latter is confined to the Atlantic 
drainage; the former belongs tothe Mississippi Valley, but has migrated into the St. 
Lawrence basin. No description was published of this form that I know of until 
that of Mr. Wright appeared.

1 Allied to ravenelianus LEA, according to Conrad. 

2In the only gravid specimen seen the outer gills were curiously wrinkled and 
folded longitudinally, though the inner gills were plain. If this were a normal 
character it would entitle the species to generic rank, but I can not feel certain that 
itis. A. triangulata seems to stand between this and the ordinary Alasmidontas.

Ohio River system; north to Michigan; west to Iowa; south to 
Arkansas; east to Tennessee. 


1Dr. Tea does not mention this in his Synopsis. 

°This species, the only member of the group, differs from Margaritana in the beak 
sculpture, the thickening of the anterior end of the shell, in the want of muscle 
scars in the shell cavities, in the color of the animal, and in having the gills united 
to the mantle posteriorly to their ends, and the shell is not that of a Unio, as it 
differs in the beak sculpture and the teeth. I regret that Lea’s well-known name 
must be displaced for the obscure one of Say, who undoubtedly had this shell before 
him when he described his Alasmodonta ambigua.

'The name Baphiv Meuschen has precedence, but was never described ; it was applied 
to amiscellaneous lot of bivalves, and is in the plural number. Retzius’ first species 
in Unio, the type of a section without laterals, is the U. margaritifer, but in 1792 
Bruguiére in Choix de Mémoires, I, p. 106, fully and carerully redefined the genus 
Unio, restricting it to species with cardinal and lateral teeth. 

2 According to Van Wahl. I have examined a great many animals taken at different 
seasons, but have never seen one gravid.

All Europe except the southernmost portion; northern Asia; Japan; 
northern North America; Iceland. Its southern limit seems to be 
about north latitude 40°. It appears to be entirely cireumboreal, except 
that, so far as is known, if is missing in the central part of the North 
American continent. Wetherby has suggested that it may have been 
destroyed in this region by the ice of the glacial epoch. It is found in 
the upper Missouri and in Canada Hast, New York, and the New Ene- 
land States.

'This is undoubtedly margaritifera, but in the types the young shells show laterals. 

2T have no doubt that this is Wargaritana margaritifera L. and not Unio complanatus 
Solander as Middendorff supposes. The specimens figured are terribly eroded, and 
the hinges are in very bad order, but they do not show laterals. 

’Numerous varieties as well as species have been made of this abundant, wide- 
spread form. Notwithstanding its enormous distribution, the widest of any Naiad 
known, I have seen no variation that seems to me to be worthy of a varietal name. 

+Retzius’ description is in Latin, and consists of ten words, and as he does not 
figure the species, it would be impossible to determine what he meant only for the 
fact that he refers to the Flussconchylien of Schriter (Iya testa crassa, p. 182, pl. 11, 
fig.2). Schréter’s figure is not a very good one, but I can have no doubt that he had 
before him the large, heavy, black Naiad, with lateral teeth, found in southern Europe. 
In general it closely resembles the M. margaritifera externally, but the epidermis is 
amore dull black, the beaks are usually higher and more strongly developed, the 
nacre is white, and it has fairly well-developed laterals. European conchologists 
seem to have quite commonly mistaken heavy, large forms of Unio batavus for Retzius’ 
species, and in a number of cases the W/. margaritifera has been taken for it.

1Tt has often been impossible to determine what species has been referred to by 
authors under the name crassus. In cases where they have cited this species from 
the north of Europe I have no doubt that they either had Margaritana margaritifera 


or Unio batavus before them. In those cases where I could not be certain as to what 


was meant I have omitted references. 

2 According to Moquin Tandon this is U. sinuatus Lamarck. 

3Lamarck refers to Encye. Méth., 1797, pl. ccoxLViul, figs. la, 1b, which seem to be 
the crassus of Retzius. Lea, who examined Lamarck’s type, says he had thought it 
was the Margaritana margaritifera, but that it had lateral teeth. (Obs. I, pp. 35, 198.) 

1 These figures look something like a heavy inflated Lampsilis alatus Say, but are 
probably the crassus of Retzius. 

‘Given to Sganzin by M. Fabert, chief of batallion of infantry, as having been 
found at St. Paul in the Isle of Bourbon, but Sganzin very much doubts the locality. 
Of course it was never found in the Indian Ocean region. 

‘A magnificent figure of this fine species, and in a, which shows the hinge, the 
laterals are plainly delineated. 

7Dr. Lea is doubtful about this being litoralis, and I am sure it is not. It appears 
more like M. crassus than anything else. 

8Dr. Lea makes this a synonym of Pfeiffer’s elongatulus, which is, I believe, quite 
near to U. pictorum. Rossmassler’s figure shows a shell very much like Margaritana 
margaritifera, but it has lateral teeth.

I'This genus was described in a Sages by Laurentius Miinter Philipsson under 
his master, Retzius, in the University of Lund, Sweden, and it is often credited to 
the former. I am informed by Professor Joh. Chr. Moberg, of Lund, that by a 
former law or custom of the university the professor was considered the author of 
all papers which a student under him defended. According to this, Retzius must be 
credited with the genus. This law was repealed in Lund in 1852.

referred to of Lister is U. pictorum; Bonanni’s drawing is more doubtful and was

'U. batavus perhaps. 

?Draparnaud gives figures 1-4 for pictorum. One and 2 may possibly be that spe- 
cies, but they look more like batavus, and 3 is certainly batavus, while 4 is probably 
pictorun. 

3 Doubtful, may be batavus. 

*It is very probable that the specimens from Amur Land and vicinity which have 
been referred to U. pictorum are a smooth variety of Nodularia douglasiw Gray, a 
species resembling it in form, but not at all closely related to it.

1 According to Kobelt in above reference, his platyrhynchus =the limosus of Nilsson. 
Nilsson does not figure his species in Hist. Moll. Svec., but refers to pl. v, fig. 10, 
in Pfeiffer’s Land and Susswasser Mollusken, which is plainly a Unio pictorwm. 
Kobelt’s figures, the latter three certainly, are genuine platyrhynchus, which I 
consider a perfectly good species.

2Pfeifter credits this to Muhlfeld in lité. It is a doubtful species, perhaps a 
variety of pictorum, but is generally smaller, thinner, and more compressed, and is 
rather more biangulate behind. Pfeifier’s two figures represent somewhat different 
forms, but they may be the same thing. 

3 Fig. 776 is probably a form of batarus.

1 Doubtfully distinet from U. turtoni. It is not quite so rhomboid as that species, 
which is also found in Algiers, but I have seen much intermediate material which 
hints at a connection of the two. 

*The magnificent work in which this species with other Uniones was figured was 
never finished, and no descriptions of the Naiades were written. The beautiful col- 
ored figures are wonderfully characteristic and are accompanied by names. 

* Credited to Parreyss in catalogue. 

‘This is quite likely only a variety of the preceding, but seems to be thinner and 
is more evenly elliptical. Von Martens believes it to be the same as Lea’s mosulensis.

‘Swainson gave the name Unio truncatus to this species in-1829, but that name had 
been applied to a Unio by Spengler in 1793. Bourguignat credits this to Ferussac 
manuscript under the name of Unio tigris. 

°Lea credits this to Ferussac manuscript in museum at Paris. No description has 
ever been published, so far as I know, though several authors have cited it and cred- 
ited it to Ferussac. A specimen in the Lea collection which is no doubt authentic is 
apparently a delicate young tigridis. 

Young shells, and it is very hard to say whether they are tigridis or terminalis.

1All these so-called species of Locard, some of which he credits to the manuscripts 
of Bourguignat and Lortet, have high beaks placed at some distance from the anterior 
end, are wedge-shaped and more or less pointed posteriorly. I think it quite probable 
that all of them, together with the next species, are mere variations of Bourguignat’s 
old U. terminalis. Of course Locard has figured every possible variation and distor- 
tion and called it a species.

Orontes River, Syria. 
(Group of Unio littoralis.) 


Shell rather solid, subinflated, rounded rhomboid, with a faint pos- 
terior ridge, usually slightly biangulate behind and often becoming 
arcuate when old; beaks prominent and full; beak sculpture consisting 
of numerous rather fine, subparallel ridges or corrugations which are 
sometimes a good deal broken up, and which extend well out on the 
disk, but begin at the beaks as normal, somewhat coarse Unio sculpture, 
sometimes with fine radial lines posteriorly; pseudocardinals rather 
solid, subcompressed, smooth below; laterals straight or slightly curved; 
cavity of the beaks rather deep; muscle scars distinct. 

I have never seen the soft parts of any member of this group. 
Quite a number of descriptions have been published of various nominal 
species, most of which go into details as to the color of the different 
parts, but do not give an atom of information as to real characters. 
The animal is dark or highly colored, and seems to be gravid in sum- 
mer, and no doubt carries the young in the outer gills alone. Gills 
large, wider behind, inner the larger, especially in front; mantle thick- 
ened at the edges; palpi very large, elliptical, rounded behind, hanging 
at an angle of 45°; branchial opening large, strongly fringed.’ 


1] think this is a form of grelloisianus. Some forms of the latter are very much 
like U. tigridus Bourguignat, but he says that it has roughened beaks while those 
of tigridis are always smooth. 

2I have only seen the type, a young shell, and its relations are doubtful. The 
sharp, rather pustulous, beak sculpture, and the shining, yellowish epidermis are 
like the pictorum group, but its form is peculiar. It may not come from Syria at all.

‘Lamarck refers this in the Animaux sans Vertébres first to his Systeme An. sans 
Vertébres, published in 1801, and thirdly to Draparnaud (Ilist. Moll. Fr.,1806). Dra- 
parnaud published this species under the name Unio littoralis without a figure in the 
Tableau Mollusques de France, 1801, which appeared, according to Moquin-Tandon, 
about July 1 of that year. I do not know which has priority, but Lamarck refers 
to a characteristic figure in the Encyclopédie Méthodique (1797), thus fixing the 
species without a doubt, and as he is most generally considered its author I shall 
eredit it to him. 

2 Fig. 743 is a small U. littoralis. I think 747 is U. batavus. 

5Only a partial inside view is given of two valves. Schumacher says it very 
much resembles U. corrugatus Retzius, but is larger, and the teeth are very different. 
I believe it isa U. littoralis. 

‘Lamarck refers this species to the Isle of France. Sganzin states (Mém. Soc. 
Hist. Nat. Strasb., 1840-46, p. 8) that the amateurs he consulted in that island 
assured him that no such mollusk was found there. According to Lea it is Unio 
littoralis.

1 Lea and Ferussac both referred this to littoralis after examining Lamarck’s shells. 
I have seen specimens in the collection of the former from the Jardin des Plantes, 
Paris, which are, no doubt, authentic, and which, I think, perhaps, are specifically 
different from littoralis, being much shorter and more rounded. 

2A specimen of thisin the U.S. National Museum collection, from Tristram, labeled 
as above, is the same as Lea’s examples of semirugatus. 

Published as Unio maris-galilwi in list in Comptes Rendus, XCI, p. 502; but not 
described. 

4Some of these approach very close to specimens of U. littoralis, especially to the 
form called U. rothi Bourguignat, which I have placed in that species, and I should 
not be surprised if there was an absolute connection between the short, rounded 
forms of U. semirugatus and the longer rhomboid JU, littoralis.

1 Kobelt supposed this to be the U. hueti of Bourguignat, and figured and described 
it for that species. It is, however, very distinct, and I therefore am compelled to 
give it a new name. 

2Tristram only describes this in Latin, and does not figure it; and as I have never 
seen an authentic specimen I am obliged to depend on Kobelt’s figure, which agrees 
well with Tristram’s diagnosis. These make it a large, somewhat sulcate form, 
shaped like batavus, but more compressed and having a beautiful purple nacre. 

3 There does not seem to be any essential difference between the Algerian and the 
Syrian shells, which I have referred to this species. 

4 Bourguignat says he has received numerous specimens of this from Drouet, labeled 
U. turcicus Parreyss, but Parreyss’s names. were only in manuscript, and were never 
published, and have therefore no scientific standing. 

5 Only the type is in the Lea collection, and it appears to be a delicate specimen of 


duricui.

'T have only seen a single, badly eroded specimen, the type, but it seems to differ 
from anything I know. It probably belongs to this group. 

2Lea’s only shell, the type, consists of two opposite, odd valves. One of these may 
possibly be an elongated batavus, the other appears distinct.

} Ghai refers to the figure by Chemnitz in Conchylien Cabinet, VI. This feue 
is probably a light-colored batavus. 

* Tig. 3 is certainly batavus, and figs. 1 and 2 may be. 

* Maton and Rackett de not figure their species, but refer to several figures. The 
first is in Ginanni, Opere Postume, 1755, pl. rv, fig. 17. This work I have not seen. 
The figures referred to in Schréter’s Flussconchylien, in Chemnitz, and the Eneyclo- 
pédie Methodique (pl. 248, tig. 3) are what we understand as U. batavus, the latter 
being the one cited by Lamarck. 

‘Lamarck does not figure his species, but refers to plate CCXLvil, fig. 3, in the 
Encyclopédie Méthodique, which is the species commonly known as Unio batavus.

‘Nilsson claims that this is Retzius’ species, and that it is found in the rivers of 


Sweden. 


His Latin description is so brief that nothing can be made out of it. I 


have no doubt that he had Unio batavus before him when he wrote it. 

21 believe that this is a rather large batavus and the figures are almost exactly like 
those he gives of that species. 

°Claimed to be crassus of Retzius, but he gives U. ater of Nilsson as one variety 
and batavus Lamarck as another.

1Rossmassler credits this and several other species to Zeigler. So far as I am 


able to learn these are mere manuscript names. Neither Moquin Tandon or Locard. 


give Zeigler as an author in their bibliographies of writers on French mollusks, and 
Lea refers only to his manuscript. I have not seen his Systematisches Verzeichniss. 

2Generally credited to Krinické, who published the naked name in Bull. Nat. Mosce., 
1857. 

3 Fig, 280, said to be this, is probably U. twmidus. 

4 Both these species of Manduyt are batavus? according to Moquin Tandon.

Shell triangular rhomboid, solid, inflated, with a distinct posterior 
ridge; beaks rather full, their sculpture consisting of numerous some- 
_what irregular corrugations which pass into the pustulous sculpture of 
the shell; surface of the valves generally more or less sculptured with 
chevron-shaped or zigzag ridges or corrugations, which often break into 
pustules, the posterior slope bearing curved, radiating plications which - 
are likewise sometimes nodulous; epidermis dark, scarcely rayed; pseu- 
docardinals strong, radial, ragged; laterals heavy, obliquely striated; 
beak cavities not deep, compressed; muscle scars well impressed; 
nacre purple, with bronzy or coppery shades. 
Animal apparently not different from that of other related Unios. 
I have not seen any with the marsupium filled.

1 Probably a mere variety of semigranosus. It is quite likely that when a sufficient 
amount of material is examined this and some other species of this group will have 
to be placed in the synonymy. 

2¥ischer and Crosse think that testudineus is perhaps only a local race of semigra- 
nosus. I think it is quite likely they are right.

behind, with a moderate posterior ridge; beaks low, the sculpture con- 
sisting of a few very strong ridges which run parallel with the growth 
lines; epidermis dull and clothlike; pseudocardinals strong, rough; 
laterals granular or verticaily striated, club-shaped; beak cavities 
very shallow; one or more slight furrows or ridges occur in the cavity 
of the shell which run nearly parallel with the laterals; muscle scars 
very deep and distinct. 

Marsupium occupying the entire outer gills; branchie large, curved 
below, inner the wider except at the posterior end, free from the 
abdominal sac only part of their length; mantle very thin, with thick- 
ened edges; branchial opening generally large.

1 Probably another variety of semigranosus. 

This name was given by Lamarck to the species under consideration before that 
of Barnes, but Say had already used the name nasutus for a Unio, hence gibbosus 
must be used. 

5In 1820 Rafinesque bestowed the name Amblema gibbosa on some unionoid mollusk 
which I can not determine. Since then Conrad in 1836, and others after him, have 
used the specific name as of Rafinesque and applied it to a Unio, which they have 
figured and described. Barnes applied the name in 1823, properly characterizing it, 
and it must stand, because at that time it had not been used in the genus Unio.

'Lea’s type of sloatianus is an old, arcuate shell, while the type of atromarginatus 
is young and quite different looking. But the young plicate atromarginatus gradually 
changes into the smoother sloatianus as it crows older, and specimens of both show 
the dark bordered nacre, though it is more pronounced in the young shells.

1A puzzling form. The type, the only shell in the Lea collection, is rather solid, 
and the posterior ridge is curved slightly upward in the middle. Other specimens 
in the museum are less solid, the posterior ridge is sharper, and straight or curved 
down in the middle, and there seems to be almost a connection with the very different 
U. hartwrighti. 

2This name was applied to another species by Newcomb, and was used by Wright 
in the Check List, by Pietel and others, but the form to which it was given was 
believed to be a synonym of something else, and it was never described. Mr, 
Wright has again used the name for what is probably a valid species. 

°The figure of this shell is not at all accurate, being considerably more blunt 
posteriorly and inflated below than the specimen sent as the type. It approaches 
U. monroensis, but is more elongated, and a series of specimens sent by Mr. Wright 
almost connects it with U. dorei.

upward and swollen where they cross the posterior ridge; surface 
concentrically striate and often sculptured with curved, subradiating

Southern Texas to New Leon, Mexico. 


‘Mr. Wright has sent to the Museum under the above name two quite different 
forms, neither of which is like the figure. From an examination of the first one 
sent, an old, worn shell, and the figure, I believed it to be a form of U. obesus (see 
Proc. U. S. Nat. Mus., XV, 1892, p.428). Specimens sent since by Mr. Wright and 
said to be typical approach U. hartwrighti, but are more compressed and elongated. 
These forms are exceedingly puzzling. 

?An aberrant species. The shell is inflated, thin, and hasa strong posterior ridge. 
It has characters of both the Buckleyi and Crassidens groups. 

“Close to pigerrimus apparently, and may be but a variety of it; it is a lighter, 
longer shell, is less sculptured, and dces not have a rose-colored nacre.

(Group of Unio buckleyi.) 


Shell oval, obovate, subtrapezoidal, or elliptical, with a more or less 
developed posterior ridge, often biangulate behind, compressed or 
inflated, thin or somewhat solid; beaks generally full, sculptured with 
several rather strong concentric ridges, which are either nearly paral- 
lel with the growth lines or slightly doubly looped; posterior slope 
often faintly wrinkled; epidermis usually smooth and shining in the 
younger shells, often rough when old, becoming darker with age, rayed 
when young. Hinge teeth solid or compressed; nacre mostly brilliant, 


1This group is exceedingly close to that of U. buckleyi, according to the shell char- 
acters, and some specimens of U. liebmanni are so near others of U. buckleyi as to 
deceive even experts.

1The relationship between the Buckleyi, Crassidens, Complanatus, Downiei and Fish- 
erianus groups is very close. That of Crassidens is characterized by inflated shells 
with a strong posterior ridge, and wrinkles on the posterior slope; of Buckleyi by a 
less developed ridge, the absence of strong wrinkles, and a rich, warm texture 
of shell; of Complanatus by trapezoidal, not greatly inflated shells of dull texture. 
The species of the Fisherianus group have elongated, generally compressed, thin 
shells, pointed behind, and of the Downiei assemblage solid, inflated shells. But 
there are many species that are quite negative in characters, and others that com- 
bine the features of two or more groups, that can not be satisfactorily placed. 

?The type is a large, badly eroded shell, apparently a little injured at the upper, 
anterior part, and is truncated a little there. 

°The type is a small, old shell, which has become reugh and arcuate. 

4Credited to Manatee River, Florida, Simpson and Miakka Lake, Florida, New- 
comb, by Mr. Wright. I have never found it in the Manatee River, but obtained it 
in abundance in Miakka Lake. 

° Although the type is very different from that of U. buckleyi the two species ap-. 
proach so closely that there are specimens which I can not name.

‘From an examination of specimens sent to the U. 8. National Museum by Mr. 
Wright I referred this to U. buckleyi, in Pr. U.S. Nat. Mus., XV, p.417. The type is 
now in the U. 8S. National Museum, and I believe it to be a rather compressed, 
bright young U. jayensis. 

2A form of coruscus a little less solid and inflated than the type, and quite brilliant. 

2This name occurs in B. IL. Wright’s Check List, but the species was not described

1 Unio arctatus is a widely distributed, abundant, and variable species, ranging 
from the Black Warrior River to southern Florida. I have examined a great amount 
of material from the Black Warrior and Cahawba rivers (collected by Call), from 
the Flint and Chattahoochee rivers from the Lea and other collections, and I feel 
reasonably sure that all the species I have united should go together. 

2T believe this to be a small, somewhat inflated form of arctatus.

! This was first published in the Joliet Weekly News, a newspaper, May 1, 1891. 
It is a puzzling form, having something the shape of the variety orcutti of U. buck- 
leyi, but has plications on the posterior slope such as are found in the Crassidens 
group. 

2T do not know where to place this form, of which I have only seen the type. 
The figure is not very accurate, and I formerly thought it a variety of U. buckley?, 
but on seeing the type I believe itis not that. Itseems to combine characters of the 
Buckleyi aud Crassidens groups.

(Group of Unio complanatus.) 


Shell elongate trapezoidal, moderately solid, but little inflated, nearly 
straight below, with a posterior ridge, usually biangulate behind; 
beaks not prominent, sculptured with several coarse, parallel ridges 
which follow the growth lines or are nearly straight. Hpidermis some- 
times shining and feebly rayed, becoming rough and rayless with age; 
laterals straight or slightly curved; beak cavities shallow. 

Animal with the marsupium occupying all or nearly all of the outer 
branchiz; gills long, rounded below, inner much the larger, free nearly 
or quite their whole length from the abdominal sac.

*Unio complanata DESHAYES, An. sans Vert., 2d ed., VI, 1835, p. 559; 3d ed., II, 
1839, p. 676. 


| This species was described by Solander in Latin, but the manuscript was never 
published and is now in the British Museum. Mr. Edgar A. Smith kindly examined 
it for me and informed me that Dillwyn’s description in the catalogue is a transla- 
tion from Solander. The name Mya complanata was used by Lister in Hist. Sive. 
Conch. (1770, p. 150), but Lister was not a binomial author. The Portland catalogue 
is anonymous, and a mere sale list. I have done my best to straighten out the syn- 
onymy of this variable and exceedingly puzzling group, and have examined nearly 
all the types and a great amount of material. In some cases, as in the Buckleyi 
eroup, there seem to be no specific lines whatever.

1A large, compressed form, biangulate behind, the posterior point elevated above 
the base line. Certain specimens are considerably inflated in the post basal region. 
This is generally taken for U. complanatus, but it differs in the characters given 
above, and seems to be merely a northern variety of roanokensis.

1So written in first description. A typographical error, probably. Dr. Lea after- 
wards changed the name to oblatus. 

2Dr. Lea credits this to Ravenel’s letter, but neither he nor Ravenel ever described 
it so far as I know. 

3’ Ravenel here credits this species to Lea. Lea’s specimens, received from Ravenel, 
are marked Santee Canal and South Carolina. They are rather thin and delicate, 
of a peculiar texture, and have a shining brownish green epidermis.

(Group of Unio fisherianus.) 


Shell elongated, rather thin, subeompressed, pointed behind and 
sometimes slightly biangulate; posterior ridge generally well developed; 
beaks low, the sculpture consisting of a few coarse, slightly irregular 
ridges which run nearly parallel with the growth lines, generally 
heavier where they cross the posterior ridge; epidermis sometimes 
rayed, shining; pseudocardinals usually compressed; laterals long, 
straight, and lamellar; beak cavities very shallow and containing two 
or three dorsal scars at some distance behind the beaks; muscle scars 
well marked, the posterior ones elongated; nacre generally dull. Ani- 
mal with the gills greatly elongated, inner the larger, more or less free 
from the abdominal sac; marsupium occupying nearly or quite the whole 
leneth of the outer branchie; palpi elongated; mantle thin, thicker on 
the edge.

1T have seen a large number of specimens of what I suppose is this, none of which 
exactly agree with Conrad’s figure and description, but which I can not refer to any- 
thing else. 

2So written; no doubt a typographical error. 

’ Probably only a variety of U. productus Conrad. 

4Conrad’s first two figures (under fig.1) are certainly U. fisherianus, the third is 
a female nasutus.

1Only a Latin description was given by Tristram, and the species is not identifi- 
able. It is probably close to U. popeii, and may possibly be that. 

2 Notwithstanding the remarkable character of well-developed spines on the only 
species of this group, U. spinosus, the animal even when gravid does not present any 
striking peculiarities, and is certainly a Unio. I have seen one or two specimens of 
the spinosus with only one spine on one valve and none on the other, and one in the 
Lea collection without spines. :

1An abundant, widespread, and very variable species, and if there were no con- 
necting links it would be easy to make a half dozen species out of it. The first 
described is the Unio tetralasmus Say, an elongated, rather smooth, more or less shin- 
ing form, of which excultus, jamesianus, parallelus, subcroceus, and symmetricus seem 
to besynonymous, varying a little in form, color, and smoothness. The variety camp- 
todon of Say is quite rhomboid, and is a rather rough, dark shell, and U. symmetricus 
is practically synonymous. Variety declivis is peculiarly drawn out at the post 
basal point. Variety manubius is a large, rather smooth form, rounded on the basal 
line. All these are Southern and Southwestern forms. Variety sayi is a yellowish 
shell, with very distinct rest marks, and has a more northern distribution than the 
rest, but it absolutely blends into them. Ward sent a description of his U. sayi to 
Tappan, who published it in the American Journal of Science and Arts under date of 
1839. In Part XI of the Monography, dated November, 1838, Conrad describes Unio 
sayanus (changed to sayi in his notes) and refers it to Ward in the American Journal 
of Science and Arts of 1839. There is some mistake in these dates. In giving the 
synonymy it is hard to tell in all cases just what authors have meant.

1Unio sayanus on plate, U. sayi in note. 

*This species almost merges into obesus on the one hand and the southern forms of 
tetralasmus on the other. The distribution of obesus is eastern, that of tetralasmus 
western, while columbensis occupies a central position in streams of the Gulf drainage. 

*It is impossible to tell from the very poor figure what this is. Lea thinks it is 
Margaritana margaritifera, but Bose did not visit any region where that species is 
found, and the figure seems to show lateral teeth. It is quite probably U. obesus. 
I think Lea’s name had better be used.

1Under this name Dr. Lea has certainly described two species, a heavy quadrate, 
form biangulate behind, with purple nacre—a variety of complanatus—and another 
which is, no doubt, U. obesus, and is the shell figured. 

2A rough, apparently diseased obesus. 

3A decidedly trapezoidal form with cloth-like, dark epidermis, possibly worthy of 
a varietal name. The transition to the typical state is, however, very complete.

angular, ragged; laterals reaching nearly or quite to the pseudocar- 
dinals, double in both valves, in the right valve the inner being smaller; 
muscle scars deep, the posterior rounded; cavity of the beaks shallow; 
nacre silvery; male and female shells essentially alike. 

Animal having the inner gills much the larger, rounded below, free 
from the abdominal sac for a part or all of their length; marsupium 
occupying the entire outer gills, the ovisacs in some cases seeming to 
be arranged in pairs; animal generally yellowish to salmon red, some- 
times more or less brown or blackish. 


(Group of Pleurobema clava.) 


Shell solid, triangular; beaks high, generally anterior; beak sculp- 
ture consisting of three or four broken, coarse, irregular ridges; epider- 
mis yellowish or tawny, marked with broken green rays which show a 
tendency to form square spots; pseudocardinals often somewhat length- 
ened and more or less parallel with the laterals. 

Animal having the inner gills the larger except at the extreme pos- 
terior end, free nearly or quite their whole length from the abdominal 
sac; marsupium occupying the entire outer gills; branchial opening 
rather large, with small papilla; anal opening with minute papille or 
erenulations. Animal dirty whitish to salmon.

'T regret that I have not been able to examine more of the animals of this group, 
especially those of the gravid females. The shells on the one hand approach very 
close to those of Quadrula in appearance, and to Unio on the other hand. But all of 
them have shallow beak cavities, while those of Quadrula are deep, and the embryos 
of Pleurobema are contained in the outer gills only. The shells are generally more 
solid and more triangular than those of Unio, and the pattern of coloring is different 
from that of either genus. It stands between the two genera. I place Unio wsopus 
and varicosus in Pleurobema with some hesitation, though in a specimen of the 
former containing comparatively few embryos there were none in the inner gills, 
and their beak cavities are shallow.

‘No specimen in the Lea collection exactly agrees with the figure of this species 
and Lea gives no exact locality for the type; but from a careful study of his shells 
and the figure and description I am convinced that it is a somewhat compressed form 
of the very variable clava, which has rather low beaks, that are not placed as far for- 
ward as usual. There seems to be a complete set of intermediates. 

2Dr. Lea is inclined to believe (see above citation) that Conrad’s Unio maculatus 
is the same as his own ravenelianus, and if this were the case Lea’s name should have 
precedence. From an examination of specimens in the Philadelphia Academy of 
Natural Sciences and Conrad’s figure and description, I am forced to differ from Dr. 
Lea, as I consider the species close to Lamarck’s clavus. 

3 The type, a young shell, is certainly the same as Unio lawti, and there does not seem 
to be any material difference between it and the types of U. bellulus and mundus. 
The figure is hardly accurate.

1In the errata Reeve says this is not mundus, but that it is nearer cuneolus and

nearer mundus than either of the other mentioned species.

which belongs to the complanatus group. Lea’s name, ravenelianus, appeared in 
August or September of the same year. Conrad, claiming priority for his name, 
substituted that of Unio rudis for Lea’s species. As the names are really different, 
that of Lea had better stand.

(Group of Plewrobema decisa.) 


Shell solid, inflated, ovate to elliptical, very inequilateral, somewhat 
truncated in front and rounded or bluntly pointed behind, wedge- 
shaped when looked at from above; base slightly angled in front, then 
nearly straight for two-thirds of its length, from whence it curves to 
the posterior point; beaks high, curved inward and forward; beak 
sculpture consisting of a few coarse, irregularly concentric ridges 
which curve slightly upward behind; epidermis tawny to brownish, 
rayless, the rest periods very distinctly marked by dark bands; pseudo- 
cardinals stumpy, ragged, often showing a tendency to elongation in 
the direction of the axis of the shell. 

Animal having the branchi rather small, inner the larger, free nearly 
or quite the entire length of the abdominal sac, marsupium occupying 
all but the extreme posterior end of the outer gills; branchiz and anal 
openings papillose.

Coosa River system; Columbus, Georgia? 
(Group of Plewrobema curta.) 


Shell elongate triangular, truncated in front, rounded on the base 
where it is quite full behind the middle, with a low posterior ridge, the 
space between the middle of the disk and the ridge flattened or some- 
times slightly excavated, rather sharply pointed behind; umbonal 
region very prominent; beaks well forward; beak scuipture not ob- 
served; epidermis rather smooth, brownish olive; pseudocardinals dis- 
tinet, triangular, radiate; laterals heavy, slightly curved; cicatrices 
small and deep; nacre iridescent posteriorly. Animal with the gills 
large, semicircular, the outer slightly larger than the inner, which are 
free nearly their whole length from the abdominal sac; marsupium 
occupying the entire length of the outer gills. 


‘Probably did not come from Chattanooga, Tennessee, as Dr. Lea believes, but 
from some of the streams of northern Georgia or Alabama, which drain southward. 
According to Hon. T. H. Aldrich, the animal of this and allied species is a brilliant 
scarlet.

1Conrad says this is between Unio ellipsis Lea and mytilloides Rafinesque, but that 
he has no doubt that it is the latter. It is certainly very different from the shell 
Rafinesque figures and describes as Pleurobema mytilloides. (Ann. Gen. Sci. Phys. 
Brux., XIII, 1820, p. 313, pl. Lxxxur, figs. 8-10.) Conrad’s Unio cor was published in 
May, 1834, and his mytilloides in January of the same year, so that the latter has 
priority, but as Rafinesque’s name was placed under the genus Pleurobema, and as I 
place Conrad’s species, which is an entirely different thing, in the same genus, the 
name mytilloides can not be used for it, and it must therefore take the next name 
proposed, which is Conrad’s cor. 

Dr. Lea admits Rafinesque’s mytilloides with doubt, and in his collection places 
under that name specimens which I regard asa rather elongated Quadrula pyramidata. 
Rafinesque’s figure represents an elongated shell, almost absolutely straight on the 
dorsal line, and with the beaks carried far in front of the rest of the shell. I have 
never seen any thing which at all agrees with it.

?Very close to P.irrasa, and it may be that when a sufficient amount of material 
is examined the two will have to be placed together.

'The single species which I place in this group is quite variable. Some specimens 
approach Quadrula solida and trigona in general shape, while others are more like 
! leurobema irrasa and troscheliana. I judge from the character of the gills that the 
iarsupium is confined to the outer pair.

1Conrad says that U. ravenelianus of Lea is the same as his U. rudus, which, accord- 
ing to Ravenel, is found in the French Broad River, though Conrad obtained his 
species in the Black Warrior. The species of Conrad is, however, quite distinct from 
that of Lea, the two never occurring in the same drainage system. 

2T have seen what I believe are specimens of this species from the collections of 
the Hon. T. H. Aldrich and Mr. Bryant Walker, taken from the Black Warrior 
River, Alabama, but I think it not improbable that it may run into P. rubella.

latter, and some of the species seem to show relationship with such forms as P.

1T am not positive as to the generic position of the two following species, but I am 
inclined to place them in Pleurobema. No other living species of this genus has any 
development of tubercles, but a great number of fossil forms from the Tertiary of 
eastern Europe which seem to be most like Pleurotema are decidedly pustulous. 
The heavy, inflated, high beaks and the comparatively shallow beak cavities are 
characters found in all the species of this genus. In the single gravid specimen I 
examined (one out of a large number from different localities) the outer gills were 
not filled very full of ova, though they were found throughout their extent, while 
the most careful search did not disclose any in the inner gills.

Kotundaria AGassiz, Arch. fiir Naturg, 1852, p. 48. 

Orthonymus AGassiz, Arch. fiir Naturg, 1852, p. 48. 

Shell triangular, quadrate or rhomboid, solid, inflated, with rather 
prominent beaks, which are generally sculptured with a few coarse, 
irregular, subparallel ridges that are inflated where they cross the 
posterior ridge; posterior ridge ordinarily well developed; base often 
incurved in old specimens; disks sculptured or smooth; epidermis 
usually dull colored, dark and rayless, or feebly rayed; hinge plate 


'T change Lea’s name because Lamarck previously applied the name Unio varicosa 
to what is, no doubt, Alasmidonta marginata. Mr. T. G. Lea, of Cincinnati, took 
many specimens of this species, the shells of which he sent to Dr. Lea, and in several 
of them he has written in pencil “(not charged” or ‘ovaries charged,” with the 
date, but neither of them seems to have described the animal. I am somewhat ata 
loss to know where to place this curious form. The young are much like those of 
Quadrula solida, and do not show the swellings until the third or fourth year, and 
occasionally the adult shell is nearly smooth,

heavy, wide, flattened; pseudocardinals solid, direct, ragged; laterals 
double in the left and single in the right alee, often with a small 
secondary lateral below the large one in the right valve; cavity of the 
beaks deep and compressed; dorsal scars under the hinge plate; male 
and female shells alike. 

Animal having the inner gills the lereer! generally se from the 
abdominal sac the greater part or all of their length; marsupium 
occupying all four of the gills throughout, the whole Seno ola and pad- 
like. 

Section CRENODONTA Schluter.1 


(Type, Unio plicatus Say.) 


Shell more or less alate; beaks prominent; the surface of the valves 
usually sculptured with oblique folds; posterior slope generally having 
smaller radial plications which curve upward behind; epidermis brown- 
ish or blackish; anterior muscle scars large, distinct, very shallow, 
the anterior edge smooth, the rest apparently filled with roughened 
Shelly matter; posterior scars large, shallow, indistinct; escutcheon 
large and dark. 

Animal with the gills generally large, rounded below; inner the 
larger, usually free nearly or quite the entire length of the abdominal 
sac,” the two pairs united to the mantle nearly but not quite to the 
posterior end, having a small portion free; marsupium occupying all 
the four eens hea forming very heavy, thick a labial palpi usually 
large. 


(Group of Quadrula plicata.) 
Shell rounded to subrhomboid; plications usually strong, oblique, 


though in occasional specimens the surface may be perfectly plane or 
slightly concentrically sculptured. 


'Schliiter applied the name Crenodonta (Verz. meiner Conch., 1836, p. 33) to a group 
of Unionidz, the first species of which was the Unio plicatus of Say, but he gave no 
description of his group and did not designate a type. In 1853 Mérch (Yoldi cata- 
logue, p. 45) used this name without a description or a type, and it has been applied 
to the plicate Uniones by von Martens (Biologia Centrali-Americana, Mollusca, 
1900, p. 479). 

2Dr. Lea found in Quadrula multiplicata the inner gills generally nearly or entirely 
free, but in certain specimens they were wholly united. My own experience in exam- 
ining the animals of this species exactly coincides with his, thus showing that the 
character of the union of the inner gills with the abdominal sac, or their separation 
from it, is not a generic character, as Agassiz believed, nor is it even of specific value. 
Although I have examined thousands of animals belonging to the Plicata group 
of the genus Quadrula, taken at various seasons and throughout almost the entire 
range of the assemblage and of nearly all the species, I have never seen a speci- 
men with ova or embryos in the gills save one in the alcoholic collection of Dr. Lea 
in the Academy of Natural Sciences at Philadelphia. Other students of the Union- 
ide have found these species equally barren. It is probable that they breed only at 
long intervals but in enormous numbers, a supposition strengthened by the fact that 
Dr. Lea found about 6,000,000 young in the gills of a single Unio multiplicatus.

1This seems to be merely a form of perplicata, with a rather rude growth and 
roughened epidermis. 

2A comparatively smooth form of perplicatus, according to the type. 

3 Another smooth form of perplicatus. 

4The above is a fair sampie of Peetel’s orthography throughout his work. 

5A right valve of the type was kindly loaned to the writer by Mr. Quintard. It 
is a rather light brown, glossy shell, and is sculptured with a series of j-shaped 
markings on the disk. Otherwise it is generally like Q. perplicatus. I have seen 
the @. wndulata and one or two other species of this group break from the ordinary 
oblique bars into these peculiar markings, and I am quite sure that in this case the 
same thing has happened to Q. perplicata. 

6Dr. Lea first called this Unio atrocostatus, and then wrote in one of his duplicates 
Unio elliottii. He says that it is very near to U. perplicatus Conrad, but that the 
young of his species have a yellow stain on the posterior part of the nacre not found 
on any other species. I have, however, found it on young atrocostatus in his collec- 
tion. I am strongly inclined to believe that the elliottii is only a peculiar, vigorous 
variety of perplicata, but do not feel quite certain of it, and so let it go as a species 
with doubt,

1 More compressed and having finer, more delicate plications than the type. I 
have traced it northward into Kansas, where it gradually assumes the ordinary form 
of undulata. Occasional specimens are found in the Northern States which agree 
very well with the typical latecostata. 

J feel quite sure that this is only a peculiar variety of wndulata. 

SA peculiar shell belonging to Mr. J. H. Ferriss, of Joliet, Illinois, from Lake Win- 
nipeg, has been examined by the writer. It has unusually strong growth lines and 
is quite full in the ventral region, and has only the very faintest vestiges of plica- 
tions below the lower part of the posterior ridge. J regard it as a smooth form of 
Q. undulata, and if any considerable number of such specimens were found it might 
be worthy of a varietal name.

1There has been some dispute as to what name should be applied to the above 
species. In 1829 Say fully described in the New Harmony Disseminator a species 
which he called Unio heros, but didnot figure it. Later in the American Conchology 
he placed it in the synonymy of Unio undulatus Barnes, though the figure which he 
gives as undulatus in that work and to which his description refers is plainly not 
Barnes’s species, but the heros described in the Disseminator. In 1831 Dr. Lea 
described Say’s species as Unio multiplicatus. Notwithstanding the fact that Say 
placed his own species in the synonymy, it is perfectly distinct and was properly 
characterized in his description, and his name will have to take the place of the bet- 
ter Known one of Dr. Lea. ,

'Very close to Quadrula nickliniana Lea, According to von Martens in the above 
citation the Unio nickliana of Kuster (Conch. Cab. Unio, new ed., p. 218, pl. Lx x1, 
fig. 3) is not the nicklinianus of Lea, but a new species which he calls Unio stolli. I 
can not agree with him, as it seems to me that Kuster’s figure represents Lea’s 
species very well. The figure and description of U. stolli given by von Martens rep- 
resent a more elongated and more plicate shell than the typical nicklinianus of Lea, 
but Iam doubtful whether it is distinct. Lea’s shells of both forms are mostly from 
the Moctezuma River, which is in Central America according to Lea, but the only 
river of that name I can find is in New Leon, Mexico. Part of von Martens’ work 
describing the Unionidz of Central America has been received as the Synopsis is 
going through the press, and for the most part too late to avail myself of the large 
amount of valuable information it contains.

1In 1820 Rafinesque applied the name interrupta to some, to me, unknown Unio, in 
Ann. Gen. Sci. Phys. Brux., but as he placed his species in the subgenus Plagiola of | 
the genus Obliquaria and not in Unio at all, it does not have priority in the latter 
genus. In 1831 (December, according to Dr. Lea) Say described in the Transyl- 
vania Journal the species which Dr. Lea called Unio trapezoides as Unio interruptus. 
In the latter part of the same year (I am unable to ascertain the exact date) Dr. Lea 
published his name in the Transactions of the American Philosophical Society. As 
I have found it impossible to determine which name was actually published first I 
have used the better known—that of Dr. Lea. 

2This is Unio trapezoides Lea according to Lea, who examined the Lamarckian 
types. See Synopsis, 4th ed., p. 37, footnote.

1By common consent this species—which is a most striking one—has been allowed 
to stand to the credit of Ratinesque. The outlines of the figures bear some resem- 
blance to the species. 

2Tt is hard to tell from these figures just what Barnes had before him when he 
described this species. They are as much like metanevra as anything.

Section THELIDERMA (Swainson, 1840) Simpson.? 


(Type, Unio lachrymosus Lea.) 


Shell rounded, quadrate to rhomboid, solid, pustulous; beaks rather 
prominent; beak sculpture consisting of a few rather coarse, subparallel 
ridges; anterior end rounded or slightly subtruncate above; base often 
arcuate; posterior end truncate, high and angled behind the ligament; 
epidermis scarcely rayed, never pointed; beak cavities rather deep. 


1It is likely that this is only a small, rather smooth variety of tuberosus. 

2Swainson’s first species of this group in the text of the Treatise is Unio irroratus, 
and after this metanevrus and cylindricus. In the final classification in the same work 
he includes in the group lachrymosus and pustulosus, and by the process of elimina- 
tion I use the name in order to save coining a new one. 


776 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXII. 


(Group of Quadrula lachrymosa.) 


Sheil quadrate or rhomboid, generally with a sharp, well-developed 
posterior ridge, in front of which is a wide, shallow, radial excavation ; 
base incurved, posterior end sharply truncate, generally slightly bian- 
cular below, high and distinctly angled behind the ligament; posterior 
tubercles often in somewhat radiating rows; earlier beak sculpture 
consisting of ridges nearly parallel with the growth lines, but later on 
becoming doubly looped and blending into the general sculpture of the 
shell; epidermis smooth; pseudocardinals strong; laterals straight; 
nacre white. 

Animal with all four gills used as a marsupium throughout, inner 
much the larger, free from the abdominal sac nearly or quite their whole 
length; palpi very large; branchial opening generally having clustered, 
often branching papillae; anal opening smooth; superanal opening 
closed below.

1Dr. Lea separated this from his lachrymosus because the latter had tearlike 
nodules, while those of asperrimus were simply elevated. The two forms absolutely 
run together, and specimens may be found in which both varieties of nodules occur. 
There are forms which are almost smooth, and there is great diversity in the matter 
of inflation. Dr. Lea finally came to doubt whether the asperrimus was valid. 

2] think that this is a solid, inflated variety of lachrymosus. From the figure, Pratt’s 
Specimens seem to have few tubercles; but I have seen quite a number of shells from 
the Ohio River north to Minnesota which resemble it in shape, but are strongly 
pustulous throughout. I was at first inclined to believe these were varieties of 
asper, but I now regard them as a form of lachrymosus, and they may perhaps be 
referred to Pratt’s variety. He describes his species as having a large lunule, but 
individuals vary greatly in this character.

1 Written tragosus in text, no doubt a typographical error, as it is written cor- 
rectly in the explanation of the plate. 

2 Say says that U. asper Lea is the same as his apiculatus. I think he is wrong. 

8 One specimen figured (fig. 2) is @. apiculata. The other (fig. 3) is a nondescript, 
possibly Q. asper, or it may be the form of Q. lachrymosus which I have placed under 
var. lunulatus Pratt. 

4Certain forms of rumphianus are very different from blandianus, being more 
inflated, and showing a high, biangulate posterior ridge and a deep radial sinus in 
front of it, while specimens of the latter are much less inflated and have a low, some- 
what rounded, posterior ridge. But the difference between the two seems to be 
absolutely briged by intermediate specimens.

1 Probably a smooth form of pustulosus. 

2The type is a nearly smooth, compressed form of pustulosus, I am sure. Lea 
includes with it in his collection a number of strongly pustulous, compressed shells. 
Quadrula pustulosa is a very widespread, abundant, and variable species. A large, 
solid, inflated, and somewhat quadrate form has been called Unio dorfeuillianus by 
Dr. Lea, and various smooth races have received names, but they so completely 
blend into the typical form that it does not seem to me they are worthy of varietal 
names. A somewhat triangular variety, often having a broad, faint ray, is found in 
the Ohio River and southward which probably equals the variety pernodosa. 

3Seems to be about the same as U. pernodosus, only a little smoother. These two 
are more rounded posteriorly, and are doubtfully worthy of a varietal name.

Texas. 


(Group of Quadrula infucata.) 


Shell small, rounded rhomboid, with a low, distinct posterior ridge, 
truncated behind and angled back of the ligament; beaks moderately 
elevated, subcentral; beak sculpture, four or five coarse, subparallel 
ridges which curve upward behind, with fine, radial ridges between 
them and the ligament; surface blackish, sculptured with zigzag or 
chevron-shaped corrugations which often become pustulous below; 
posterior slope having radial, broken wrinkles; pseudocardinals small, 
stumpy; secondary lateral of the right valve present; beak cavities 
moderately deep, slightly compressed; anterior scars small, smooth; 
nacre rather dull, purplish. 

Animal with the marsupium occupying all four leaves of the gills; 
inner gills the larger, free from the abdominal sac only part of their 
length; anal opening without papille.° 


1 An inflated form. 

2 Usually entirely free from sculpture excepting faint corrugations on the poste- 
rior slope. A specimen belonging to Mr. William A. Marsh, from Village Creek, 
Texas, shows slight tuberculation on the disks. 

3T have been puzzled as to the relationship of this group and have been strongly 
inclined to place it near chickasawhensis, but I now believe it is more closely allied 
to the Pustulosa group. Its posterior truncation, the prominent angle behind the 
ligament, and beak sculpture lead me to place it here. The general sculpture of 
@). petrina approaches that of these species.

(Type, Unio trigonus Lea.) 


Shell round, rhomboid, triangular, or short elliptical, with a moderate 
posterior ridge; beaks high and full, curved inward and forward, sculp- 
tured with a few coarse, parallel ridges which curve upward behind; 
epidermis dark; surface not sculptured; hinge plate of moderate width; 
pseudocardinals strong; nacre white, salmon, or purple. 

Ammal having all four gills occupied throughout as a marsupium, 
filled with pink or purplish ova when gravid; inner gills much the 
wider in front, free generally from the abdominal sac; outer gills cut 
away slopingly in front. 


(Group of Quadrula beadleiana.) 


Shell moderately solid, somewhat triangularly rounded, bluntly 
pointed and sometimes slightly biangular at post base, with a more 
or less developed posterior ridge, in front of which it is full; beaks not 


1A rather smooth infucatus. 

2JTn the Proceedings of the U. 8. National Museum, XV, 1892, p. 404, I united this 
species with Unio infucatus Conrad. Further study of additional material and of 
the animals which show some differences has induced me to separate the two.

(Group of Quadrula trigona.) 


Shell triangular, generally inflated, with high, full beaks which are 
ineurved and turned forward over a well-developed lunule; anterior end 
obliquely truncate above, often with a curved, shallow depression in 
each valve running from the beaks to midway down the anterior end, 
and forming a sort of secondary lunule; posterior base usually incurved; — 
the posterior ridge ending in a rather sharp point; beak sculpture, a 
few coarse, concentric ridges turned upward behind and often swollen 
on the posterior ridge, sometimes becoming finer and broken or irregu- 
lar on the upper disk; hinge solid but not very wide; pseudocardinals 
triangular and radial, torn; there is a secondary lateral in the right 
valve; cavity of the beaks generally deep and compressed; muscle 
scars small, deep. 

Animal with the marsupium occupying the whole of all four bran- 
chie; inner gills generally free from the abdominal sac, much wider 
than the outer in front; outer nearly or quite equaling them in width 
behind; anal opening distinctly crenulate or papillose.

1This was figured by Hildreth, but the figures of this species and a number of 
others were left out by the editor. 

2JIn the Transactions of the American Philosophical Society, VI, 1838, p. 12, pl. v, 
fig. 12, Lea described this species, and stated that about eighteen months previous Dr. 
Hildreth had sent him a single specimen under the name Unio coccineus; but there is 
nothing to show that Hildreth had described it. In the Monography in 1886, III, 
p. 29, pl. xm, fig. 1, Conrad describes this species under the same name, and also 
credits it to Hildreth, stating that it was in the collection of the Philadelphia 
Academy of Natural Sciences under that name. The°species must be credited to 
Conrad, who first described it, though Lea read his description in 1834.

‘Most of the authors who use the name mytiloides believe it to be Rafinesque’s 
species, though they figure and describe the pyramidatus of Lea. The specimens in 
the Lea collection which Dr. Lea calls mytiloides Rafinesque, are evidently a form of 
his pyramidatus. Rafinesque’s figure represents a shell very long and almost 
straight on the posterior dorsal line, with astonishingly high beaks, and four dis- 
tinct, equally separated rays on the disk, and he says there are some oblique, black, 
longitudinal bands on the shell. The Rafinesquian shell seems as near to the Unio 
clava of Lamarck as anything, but it does not agree with that.

1A typographical error no doubt. There is a Unio kirklandianus recently named 
by Wright. 

*A form is found in the Tennessee drainage which comes nearest, it seems to me, 
to the kirtlandianus of Lea, but is much smaller and more delicate, and is not so 
strongly colored. Mr. Wetherby believes this to be a form of the nearly allied 
subrotundus, but it seems to me too much compressed for that. Dr. Sterki is of the 
opinion that the two species should be united. While there are specimens which 
can hardly be determined, it seems to me that in the main the two are distinct. 
' The small form may be called variety minor. 

>The name subrotunda was used by Rafinesque in 1820 for some species of Naiad, 
probably a member of the Circulus group which I can not determine, and placed in 
the genus Obliquaria by him. Conrad afterwards, in 1834, placed what he supposed 
was this species in the genus Unio. Lea applied the name subrotundus to his species 
in 1831, and being the first to use it for that genus, I think it will have to stand, 
and Conrad’s name become a synonym.

1The figure looks something like subrotunda, or it may possibly be ebenus. I can 
not make out Lamarck’s brevialis (An. sans Vert., VI, 1819, p. 75), which he says came 
from the Isle de France. Sganzin was told by the people of the island that no Unio 
was found there (Mem. Hist. Nat. Strasb., III, 1846, p. 8). 

2Merely listed by Say, but neither Lea nor I have been able to find that it was ever 
described by him. 

3 Kirtland states that an oblique sulcation below the superior posterior angle dis- 
tinguishes the female of this species, as it does the retusus, from the male. I have 
not noticed it. 

4Mr. Conrad states in the Monography that his shells came from the Little Red 
River, Arkansas. Our shells in the U. S. National Museum collection are from the 
same stream, but are not quite so solid, nor are they just the shape of the figure, yet 
I have no doubt that they are cuneus,

amount of material I have seen is in a badly eroded condition. I can form no 
idea of the beak sculpture, and I have never seen the soft parts. The texture and 
coloring of all the shells I have seen are like those of Pleurobema, but the very 
deep beak cavities and the general form are like Quadrula.

marked lunule; beak sculpture consisting of numerous (20 to 30) fine, 
irregular, broken, somewhat concentric corrugations which extend 
well on to the second year’s growth and gradually blend with the regu- 
lar sculpture; posterior three-fifths of the shell tuberculate; epidermis 
brown; beak cavities very deep, compressed; nacre violet. 

Animal having the gills very large, inner very much wider in front, free 
the whole length from the abdominal sac; branchial opening immense, 
with many small papillae; anal opening very large, smooth; superanal 
opening not at all closed below.! 


(Group of Quadrula tuberculata.) 


Shell rounded, truncated behind, with a wide depression down the 
post slope. 


1T regret that I have never been able to see gravid specimens of either of the species 
placed here. They are generally placed with the pustulusus group, but the strongly 
developed sulcus on the posterior slope and the very remarkable beak sculpture, 
which is not at all like that of any of our species, are good distinguishing characters. 
The enormous anal anil branchial openings, and the open superanal opening are 
characters of some value.

tQUADRULA GRANIFERA var. PUSILLA Simpson.’ 


Ohio, Cumberland, and Tennessee river systems; northwest to Iowa. 


1 Rafinesque’s description is plainly that of one of the pustulous Uniones of the 
Ohio, and the statement that it is truncated posteriorly, wants nodules anteriorly, 
is three or more inches long, and has a violet nacre makes it certain that it is the 
verrucosus of Barnes. 

2This form has been considered by many merely at best a variety of the tuberculata, 
and I have so regarded it. It has always a smaller and generally a more inflated 
shell, higher beaks, and usually a smoother, more olive-colored epidermis than the 
latter. Its nacre is ordinarily more copper colored than that of tuberculata. I believe 
with Mr. Wetherby that it is a valid species. 

3A greatly dwarfed inflated form from the Green River at Mammoth Cave, Ken- 
tucky, may bear the above name.

ridge, that on the valve pushed forward less developed; beaks high, 
full, apparently sculptured with a few coarse irregular ridges; posterior 
slope usually having strong, radiating, upcurved ridges; hinge plate 
generally wide and flattened; pseudocardinals heavy, somewhat radiate, 
often with the sockets evenly, radially grooved; laterals strong, heavily 
vertically ridged; secondary lateral of right valve well developed, 


' A group of peculiar and striking species which presents a number of quite diverse 
forms. On account of this diversity, the fact that the beak sculpture is rarely pre- 
served, and that nothing is known of the anatomy, the group is a difficult one to 
arrange. 

2A single, rather young, dead, and somewhat decayed specimen of what I believe 
is Q. coreana, from Séul, Korea, belonging to the collection of F. Stearns has been 
examined by the writer. The Chama plumbea of Chemnitz seems to be near it, but 
is solider and shorter.

2 Wood gives four figures; the first and second being a solid, nodulous, Chinese 
species; the third and fourth seem to be Unio pictorum. Lamarck used the name 
nodulosa for a Unio (An. sans Vert., VI, 1819, p. 78), and refers to the Encyclopedie 
Méthodique, 1797, pl. 248, fig. 19, and this figure is no doubt that of Unio pictorum. 
Wood seems to have confounded the two.

Hot Springs, Arkansas, by Major Byrd Powell. I am certain this is a mistake, and 
that it is a Chinese species. It agrees exactly with Wood’s figure of nodulosa, is 
slightly pushed over or twisted on its axis, and has the vertically ridged laterals 
characteristic of the heavy Chinese forms very strongly developed. 

2 Heude’s name moreletianus has been twice preoccupied.

Subgenus DISCOMYA Simpson, 1900. 


Shell subsolid, round obovate or subrhomboid, lenticular, rather com- 
pressed, widely, faintly biangulate behind, with scarcely any vestige of a 
posterior ridge; beaks very low, sculpture not seen; front half of the 
shell densely covered with fine pustules arranged in curved rows in two 
directions as if engine chased, over which the epidermis is wrinkled. 
The hinder half is covered with fine, radiating and undulating corru- 
gations, curved upward posteriorly, which are slightly nodulous and 
show through on the inside of the shell; one slightly compressed pseudo- 
cardinal in the right valve and two in the left; one delicate, curved 


1 Virst called montanus by Heude, which was several times preoccupied in Unio. 

2Gredler makes this a variety of leai, but I believe it is a rather finely sculptured 
form of monticola. ‘The species varies much in the size of pustules and the degree of 
its smoothness, and Heude has exalted all these variations to the rank of species. I 
think it probable that when a large amount of material can be examined it will be 
found necessary to reduce some of the Chinese forms I have considered as species to 
the rank of varieties, or even to the synonymy. 

° Benson says this is not very distantly related to Unio wndulatus Barnes. It has 
never been figured, so far as I know, but from all I can learn of it it belongs in this 
group and may be Q. leai.

(Type, Unio lampreyanus Baird and Adais. ) 


Shell rather solid, triangular, inflated, truncate above in front, some- 
what swollen just behind the center of the base, pointed behind; beaks 
high; beak sculpture not seen; surface thrown up into strong, very 
wide, concentric ridges, one or two with each season’s growth, and 
pinched up in the central part to form a radiate row of compressed 
knobs or spines; epidermis shining, greenish-yellow or brownish, having 
marvelously delicate, concentric, microscopic lire, often painted with 
a few elegant, broken, green rays; there is one large, high, triangular 
pseudocardinal in the left valve under the beak, a deep, triangular pit 
in front of it, with an erect, radial lamellar tooth in its center, and a 
high, lamellar, curved tooth in front of the pit, parallel with the edge of 
the shell connected with the central tooth. A heavy triangular bifid or 
trifid pseudocardinal in the right valve stands close to the anterior 
edge of the shell and is separated from it by a deep, compressed pit; 
behind this tooth, deep down at its base, is a narrow shelf, and back of 
this the entire hinge plate is cut out in a deep sinus to the beak; two 
laterals in each valve; cavity of the beak in left valve deep, somewhat 
compressed; in the right entirely opened by the sinus; muscle scars 
sual, geek, smooth; pallial line with a sinus at its posterior end; a

ably a valid species.

Wood’s species was never placed in Unio under the specific name crassus, his name 
may be used.

Characters the same as the genus. 
(Group of Nodularia douglasie. ) 


Shell olive to blackish, subsolid; surface generally more or less cov- 
ered with nodules arranged in subradiating or chevron-shaped patterns. 


1T have seen a curious shell in the collection of Mr. Bryant Walker shaped some- 
thing like the N. grayana, but quite heavy and decidedly inflated in the post-basal 
region. It may be an old grayana, but is so eroded that I can not be certain. 

‘Schrenck supposes this to be the Unio grayanus of Lea, but it is very different. 
It is a large, heavy, cylindrical shell, apparently without sculpture, and the figure 
does not show plainly whether it has any posterior ridge. A large form between 
grayanus and oxyrhynchus is found in Korea, according to von Martens, Sitzber. Nat. 
Fr., 1885, p. 77.

'The plate in Griffith's Cie ier on Aen hig. species is figured bears date of 1833, 
and the names of the species are designated on it. The brief description (in the 
index) was published in 1834, the date of the work. Lea’s Unio murchisonianus was 
not published until 1854. This species has an immense distribution and varies 
greatly in form and degree of sculpture. 

2An author’s shell in the Lea collection is certainly a young U. douglasic. 

’'This and U. firmus and chloreus with others are given as varietal names and lettered, 

4Credited by Westerlund to Amurland. Unio pictorum, or varieties of it, have 
several times been credited to this region, but no doubt erroneously. This species 
is always darker when adult than the well-known European species, and has totally 
different beak sculpture. The two shells often resemble each other closely in form. 

5Specimens of shells bearing the above names, labeled by Westerlund, are in the 
U. 8. National Museum.

ordinary form of douglasie is found also in Japan. 

*This seems to stand between this group and that of N. grayanus. 

*The shells of some of the species of this group are very different from the normal 
Nodularia, being covered with roughish epidermis and apparently lacking sculpture. 
Others, however, show occasional sculpture, and the young shells have the green 
epidermis characteristic of the group.

1T have not seen the figure of andersonianus, but Nevill states that it is near 
ceruleus. The Nodularia cerulea isan abundant and very widely distributed form, 
and therefore quite variable in size, form, solidity, color, and sculpture, and it is 
possible that other so-called species should be merged with it. Some of the above 
might rank as varieties, but I can hardly separate them. 

? Lea credits this name to Ferussac manuscript. So faras I know neither Ferussac 
or anyone else has ever described it. Lea makes U. teretiusculus a synonym of it in 
his Synopsis. 

-3Philippi’s figure is a little more rounded posteriorly than are any of the shells I 
have seen from Africa bearing this name. After a critical comparison of numerous 
specimens, which are undoubtedly of African origin, I can only place this in the 
coeruleus group (with which it agrees in every essential character) and close to cwruleus 
itself. There are other undoubtedly close relations between species of Naiades of the 
Ethiopian and Oriental regions. 

4Unfigured. Von Martens places it inthe group of U. teretiusculus.

1T believe that Reeve’s U. inornatus = Lea’s U. asperulus. As Lea had used the 
name inornatus previous to Reeve for a Unio, he changed the name of the latter to 
U. versus. 

2A shell labeled Unio bowvieri Nevill in the collection of Frederick Stearns in 
Detroit is, I believe, the same as U. pugio Benson. I do not know if Nevill ever 
described U. bouvieri or whether it is only a manuscript name.

1Kuster credits this to Mousson, Conch. of Java, p. 92. I know of no such work, 
and the name is not found in Mousson’s L. und Suss. W. Moll. von Java. 

2Changed to this name by Lea because sumatreensis was preoccupied for a Unio by 
Dunker. 

3This species varies much in sculpture, and shows the connection between the 
nearly smooth contradens and the strongly corrugated forms like rusticus and ~ 
dautzenbergi. It is really verysclose to contradens. 

4I am doubtful whether these two are more than varieties of the same thing. 
The N. lugens is darker colored and seems to lack a little tubercle on the hinge, 
which is sometimes present in sacellus.

1Changed from siamensis to sobolus because the former was preoccupied by Lea. 
Probably an old, smooth rusticus. 

‘I hardly know where to place this, as the only shell I have seen (the type) is 
evidently young, and has the beaks eroded until I can not make out the sculpture. 
It seems most likely to be an elongated, somewhat compressed member of the con- 
tradens group.

Shell elliptical, pointed or rounded behind, usually slightly preduced

Characters the same as of the section. 


‘Notwithstanding the considerable difference between this group and all other

ceruleus group, and show the relationship of the two. 

2 The name radula was used by Say for a Unio in 1822. I change Benson’s name as 
above. Iam not positive as to the relationship of this species.

1 This species is often credited to Ferussac, but I donot know that he ever described 
it. It is considered by many to be the same as Nodularia nilotica, but the compar- 
ison of large series of material and authentie specimens in the Lea collection from 
Cailliaud incline me to separate them. There is, however, great variation in their 


characters, but wgyptiaca is a thinner, more rounded shell than niloticus, and has 
lamellar pseudo-cardinals.

1 This appears from the figures and description to be a member of the Agyptiaca 
group of Nodularia. It is possible that it came from Asia Minor, but more likely 
that it is an African species. The Unio eucyphus.of Bourguignat, which he credits 
to this region, is believed by Lea to be the U. egyptiacus of Cailliaud, and I agree 
with him. Unio bagdadensis may be merely a peculiar form of the same thing. 

2This may possibly be distinct from N. nilotica, or it may only be an oddly-formed 
specimen. 

3I can not be positive as to the systematic position of this species, but it probably 
belongs here.

1 According to Smith the above, U. verreauxianus Lea, africanus Lea, natalensis Lea, 
and vaalensis Chaper, are all one species. I think he is right, but it seems to me that 
one or two of these forms are worthy of varietal names. I have seen the types of 
most and anthentic specimens of all of them.

1Bourzuignat, by a most brilliant stroke, placed this group in the Corbiculide, 
and stated that he knew twenty-five species, and had no doubt that there would be 
at least one Jiundred when a thorough search is made. The group is an exceedingly 
difficult and variable one, and, judging from the large number of species he has 
founded on the most trivial variations, we may consider it exceedingly fortunate that 
he never saw the other seventy-five. I have seen but a limited amount of material, 
but I am led to believe that two forms of the same species often exist, as in Lamp-~ 
silis and allied genera, and which may be inale and female shells. I know nothing 
of the animal and Iam unable to do justice to the genus. :

nudum. Morch says his species is close to Anodonta zollingeri.

1T am not certain that this belongs in this group. 

2T have seen only a single shell of each of the two species of this group, both very 
badly eroded and decayed, so that I can not give the characters accurately. The 
animals may show that they are not closely related to the ordinary Pseudodons.

Shell solid, inflated, oval to subrhomboid, with full, high, zigzag, 
radially sculptured beaks, the sculpture often extending over the disk; 
epidermis smooth and bright, sometimes a little rayed, with two irreg- 
ular pseudocardinals in the left valve which are more or less broken 
into ragged denticles or are strongly, vertically striate, and two later- 
als, the lower the larger; right valve with one, sometimes two pseudo- 
cardinals, the upper small, compressed, and a few tubercles behind 
them, with two laterals, the upper the larger; cavity of the beaks 
rather deep, not compressed; dorsal scars under the hinge, not visible; 
the two upper anterior muscle scars. very deep, coniluent, the lower 
linear; nacre white to salmon, iridescent behind. 

Animal unknown. 


Subgenus PARREYSIA Conrad, 1853. 


Characters the same as the genus. 


1In the above reference Conrad gives the name Parreysia and refers to Unio multi-

'Miiller’s description of Mya corrugata is inadequate, but in the Beschaftigungen 
it is further discussed and characteristic figures are given of the species we know 
as Unio corrugatus of India. 

2Refers to Conch. Cab. VI, pl. m1, fig. 22, which is probably Miiller’s shell. 
Chemnitz refers to it as Mya corrugata teste ovali, etc. The shell referred to by him 
in Conch. Cab., X, p. 346, as Mya corrugata magna, etc., is avery different thing. 

3Lamarck refers to. Enc. Meth. Pt. 19, 1797, pl. ccxLvul, figs. 6, 8a, b. Iam not 
at all sure that fig. 6 is the corrugatus of Miiller. 

4Credited by Philippi to Parreyss. I think there can be no doubt that this is the 
Mya corrugata of Miiller, as the figure and description entirely agree with the species 
as we know it. 

5Parreyss is the author, according to Philippi. This and multidentatus are credited 
by Philippi to Australia. No shells like these have ever been found there. 

6 Lutens in text, by error no doubt.

1T think this is corrugatus and not the wynegungensis of Lea. 

2Heavier, more elongated .and pointed behind than corrugata, yet probably only 
a variety of it. 

3 Several varieties, marcens, trigona, deltw, chrysis, viridula, and densa are given by 
Benson, which hardly seem to me to be worth mentioning. 

4This = U. tripartitus of Lea, with a darker epidermis and a more pronounced 
basal swelling. There is every variation in the coloring and swelling.

1Lea claims that his species has triple laterals in the left valve. Specimens of 
favidens have the same character, and there is much variation in this particular. 

2A young specimen in the U. S. National Museum collection from Morelet’s collec- 
tion is a good deal like P. favidens. 

3Gould did not figure this, but Reeve’s figure agrees well with the types.

1 Credited to Benson manuscript. 

2The name modestus has been used by authors for a Brazilian Unio, but I can 
not find that it was ever described. Later Kuster used the name for a Chilean 
species; hence Heude changed his first name to simpularis. It is quite probable 
that this species should be placed in a separate group.

'. A. Smith, in Pr. Zool. Soc. Lond., 1877, p. 719; 1893, p. 640, believes that Unio 
kirki Lea and aferulus Lea are but varieties of Unio nyassaensis, and that Unio hermosus 
Bourguignat is identical with it. It is possible that the three forms of Lea may 
blend together, but the types are so distinct that I do not feel justified in uniting 
them even as varieties one of another. 

2There is some confusion about this shell. The form on pl. xxxiv, which Smith 
probably refers to in the text as fig. 34) is simply fig. 34 on the plate, and is, I think, 
a distinct species, which has received the name of wijiensis from Bourguignat. 
There is no fig. 34) on the plate. His 34a, which Smith calls var. tanganyicensis, is 
U. nyassaensis Lea. Bourguignat probably alluded to the fig. 34 when he bestowed 
his name, although he speaks of the var. tanganyicensis Smith. These must not be 
confounded with the original Unio tanganyicensis of Smith, which is a very different 
thing. ,

1T use Lamarck’s name for this species because the U. testudinarius and truncatus 
were only briefly and imperfectly described, and never figured, their habitats being 
given as Greenland. Lamarck refers to the figures in Enc. Méth., pl. 247, figs. 1, 
la, 1b, 1c, which very accurately represent the shell we know as Unio marginalis. 

2 Not Lea’s corrianus at all, but very different. I change the name to hanleyt.

‘Only a Latin description is given. We have two shells in the U.S. National 
Museum from the type lot, and it is, perhaps, a valid species, close to marginalis. 

2 Possibly only a variety of thwaitesii. 

Unio mainwaringi Nevill. Shells have been several times received bearing this 
name, which seem to me to be only consobrinus. I can not find that Nevill ever 
described the species.

(Type, Anodonta guillaini Recluz.) 


Shell long, elliptical, compressed, beaks rather low, said to bear con- 
centrically roughened ridges, with slight plications in front and behind 
them; posterior ridge not developed; surface shining, smooth; hinge 
line narrow, with faint, greatly elongated pseudocardinals and iaterals; 


1 Credited by Sowerby to Benson. 

2Preoccupied by Lea in 1865 for a North Carolina Unio, hence the name is changed 
as above. 

>This is figured by Hanley and Theobald as a heavy sbell, shaped much like an old 
Unio buckleyi, and quite different from the other species of the genus. But there 
is in the U.S. National Museum collection a specimen which is much thinner than 
the figured shell, and more nearly approaching marginalis in form.

with irregularly radial ridges arranged in two imperfect chevron-shaped 
loops; surface concentrically sculptured, often having irregular radial 
ridges on the posterior slope; epidermis yellowish-green or brownish, 
with two or more green rays above the posterior ridge; teeth com- 
pressed; two pseudocardinals in the left valve, one under the beak, the 
other in front, often not well separated, and two laterals; right valve 
with two pseudocardinals and one lateral; pseudocardinals all irregu- 
lar, often pitted and peculiarly dentellate; laterals granular, showing 
traces of vertical striation; cavity of the beaks rather deep, compressed ;

Genus ARCONATIA Conrad, 1865. 
(Type, Triquetra lanceolata Lea. ) 
* Arconaia CONRAD, Am. J1. Conch., I, 1865, p. 234. 


Shell greatly elongated, inflated, solid, twisted on its axis, sometimes 
- straight, but generally having the posterior end curved strongly to the 
right or left, with a decided posterior ridge on both sides of the shell, 
ending in a blunt point, with usually a small ridge above on the post 
Slope; beaks rather low, sculpture not seen, but probably zigzag radial; 


' Sowerby says nothing about teeth in his shell, whichis from Siam. The teeth of 
Lea’s specimen of U. siamensis are scarcely developed, and a comparison of his shell 
with Sowerby’s figure convinces me that they are very nearly allied. Lea’s figure 
shows the shell biangulate behind, which is an error. 

2This is not Lea’s swmatrensis, nor that of Dunker. I have therefore changed the 
name to peninsularis. I am not certain as to its relations. It is not U. comptus 
Deshayes and Jullien, as Fischer believes 

3 Gould did not figure this, and I have not seen the type. Theshell figured as this 
by Hanley and Theobald in the Conchologia probably belongs here.

often a few nodulous or wavy ridges cross the body of the shell, 
which is irregularly suleate; epidermis rayless; two pseudocardinals 
in the right valve, the upper compressed, separated from the split-up 
lower one by a parallel-sidedpit, two in the left, and two heavy laterals; 
one lateral in the right and a vestige of one below it; laterals granu- 
lated and vertically striate; muscle scars deep, anterior small, the front 
and upper united, the hinder separate, posterior muscle scars long, 
oblique; beak cavities very shallow; dorsal scars numerous, placed 
just on the inner edge of the hinge; nacre white. The lobes of the man- 
tle are not united into siphons, but separated throughout, with only a 
feeble commissure separating the anal and branchial openings.

1A remarkable Naiad, closely imitating some of the South American Prisodons in 
general appearance, to which it may be nearly allied. 

2 Unfortunately Theobald’s Latin description of Unio footei is not at all complete. 
No laterals are mentioned, and he says nothing of the color of the epidermis or of 
thenacre. The beaks were too much worn in his specimens to give any characters. 
The shell resembles some of the Arcas of the Barbatia group, and may not belong to 
the Unionidae at all.

1 The name Castalia applied by Lamarck to this genus in 1819 can not stand, as it 
was used in Vermes in 1817. I have every reason to suppose that the young in this 
and all the South American genera of Unionide are carried in the inner gills. 

?Schumacher gave only a brief description of his Prisodon truncatus, and referred 
to no figure, and the same can be said of Lamarck regarding his Castalia ambigua, 
both of which are supposed by authors to be the above species. But either of these 
descriptions apply equally well to several species, therefore they can not be con- 
sidered authentic.

Great lakes of Para, Brazil. 


1'This species, of which the type is in the Lea collection, has some of the characters 
of Prisodon and Castalina, but I can not satisfactorily refer it to either, and it is cer- 
tainly not a Diplodon. Its strong sulcation, reddish chestnut epidermis, and purple 
nacre are characters that are not possessed by any South American Naiades that Iam 
acquainted with. 

?Lea received this shell from Dr. Dunker under the name of Castalia sulcata Krauss. 
Believing it to be a Unio, he placed it in that genus, and the name sulcatus being 
preoccupied in Unio, he changed it as above. 

3In one of Lea’s shells the beaks are almost perfect, and not a sign of sculpture 
can be seen.

double, causing the shell to be biangulate behind; beaks low, with 
strong, nearly radial sculpture, the central bars coalescing below, the 
whole continuing as strong, radial, and zigzag ridges over more or less 
of the disk; epidermis thick, greenish when young, brownish or black- 
ish when old; there are two or more rather short, compressed pseudo- 
cardinals in each valve, which are much split up into denticles; one 
lateral in the right and two in the left valve; teeth often somewhat 
vertically striated ; dorsal scars numerous; nacre whitish. 

Animal with mantle lobes united together behind and furnished with 
two short, contractile siphons. (J. H. Gray.)

1Jn 1753 Klein (Testamen Méthodi, p. 135, pl. 9, fig.36) used the name Triquctra 
for the shell which has since been known as Hyria syrmatophora Gronovius. In 
1817 Schumacher founded the genus Prisodon (Essai Nouv. Systeme, p. 138), in 
which under section a he placed his P. obliquus, a smooth species considerably 
drawn out, and in section b he put P. truncatus, which is possibly the same as the 
Castalia ambigua of Lamarck. These certainly belong to two genera. Dr. Lea in the 
Synopsis used Klein’s name for the winged shell (Hyria corrugata Lamarck), and used 
the name Prisodon for Schumacher’s section b (P. truncatus Schumacher). Lea erred in 
this, because Klein was not a binomial author, and his name-can not be used. In the 
proceedings of the U.S. National Museum, XVIII, 1896, p. 315, I restored the name 
of Prisodon Schumacher to the first section, pointing out that the P. obliquus Schu- 
macher must stand as its type. Two years after Schumacher’s name appeared 
Lamarck published the generic name Hyria in the Animaux sans Vertebres, VI, 1819, 
p. 81, and placed in it first his H. avicularis, which equals Schumacher’s P. obliquus, 
and secondly H. corrugata. I now believe that these corrugated forms are generically 
distinct from the smooth ones, and as Schumacher’s Paxyodon is almost certainly 
founded on one of the smooth species, Lamarck’s name Hyria can be used by elimi- 
nation for the corrugatus and allied forms.

1 This form has the posterior wing greatly produced and curved upward. I doubt 
whether it is more than a form of syrmatophora. 

2This is probably a variety of obliquus Schumacher. 

3Only a part of the interior is figured, but from its form I think there need be no 
doubt as to what the author meant. 

4This may be only a peculiar obliquus. The dorsal line curves up in the center.

Genus DIPLODON Spix, 1827. 
(Type, Diplodon ellipticum Spix.) 
Diplodon Sri1x, Test. Fluy. Bras., 1827, p. 33, pl. XXvI. 


Shell elliptical, rounded, elongated or trapezoidal, with rather low 
beaks which are more or less distinctly radially sculptured, the ridges 
usually curved and approaching below, with a low or scarcely developed 
posterior ridge; surface slightly concentrically sculptured, sometimes 
broken into fine nodules or corrugations; epidermis dull, rayless; hinge 
with two compressed pseudocardinals in the right valve, and one 
slender lateral, and two compressed pseudocardinals in the left valve, 
one in front of the other, and two laterals; nacre bluish to white, dull, 
often blotched; beak cavities shallow; dorsal scars numerous, forming 
a row in the beak cavity parallel with the hinge line. 

Animal with the marsupium occupying nearly the whole length of the 
inner branchie, a few ovules sometimes being found in the outer gills; ” 


17 have seen only a single left valve, the type. The anterior wing of this is gone, 
and the epidermis is somewhat eroded. The shell has been injured when young, 
which has probably caused a long, low, radial furrow that runs in front of the pos- 
teriorridge. The space occupied by the pseudocardinals is not so long proportionally 
as in typical Prisodon. 

27 found a few ovules in the outer gills of D. acutirostris Lea, of South America, 
while the inner gills were full, and Mr. Henry Suter states that the ovules of D. men- 
ziezi Gray, of New Zealand, occupy the inner gills for the most part. 


No. 1205. SYNOPSIS OF THE NAIADES—SIMPSON. 873 


branchie rather large, angular at base, inner much the larger, united 
their whole length to the abdominal sac; palpi scarcely projecting 
posteriorly; mantle very thin, thickened on the edges; branchial open- 
ing papillose, separated from the smooth anal opening by a strong 
bridge; superanal opening not closed below. 


Subgenus DIPLODON Spix, 1827. 


Beak sculpture consisting of unbroken ridges, covering the whole 
beaks. 

Animal having the labial palpi rounded below and at posterior base, 
scarcely projecting behind. 


(Type, Diplodon ellipticum Spix.) 
(Group of Diplodon delodontus.) 


Shell elliptical to subtrapezoidal, inflated, subsolid, with a low pos- 
terior ridge, sometimes having a slight posterior dorsal wing; one or 
two central pairs of bars of the beak sculpture usually joining below; 
pseudocardinals sometimes slightly dentellate. 

Animal having the characters of the genus.

' Extremely close to apprimus, and probably only a young shell of that species. 

27 know nothing of this. It looks more like an Australian than a South American 
form, and is quite likely a D. australis. Kuster credits it to Charpentier mann- 
script. ! 

3A little longer and more solid than peculiaris, but I doubt whether it is distinct. 
The types of these two and paraguayensis are badly worn.

described by that author or anyone else. In 1856 Kuster properly described and 
figured a species in the Conchylien Cabinet (Vol. Unio, p. 147, pl. x11n, fig.2) under 
the name of Unio modestus, which he credits to Charpentier’s manuscript, a different 
shell from that referred to by Lea and the Adams brothers. If the latter was never 
described the name modestus can not be used for it, as it was first properly applied to 
another species. The shells in Lea’s collection may be described as follows: Shell 
smalJ, subrhomboid, rather solid; beaks full with radial sculpture, the two middle 
bars coalescing; surface faintly concentrically sculptured, dark olive; two com- 
pressed pseudocardinals in each valve which are strongly obliquely striated; two 
laterals in the left valve and one in the right; anterior muscle scars distinct; 
nacre bluish; beak cavities shallow. Length 28, height 17, diameter 13 mm.

1Barnes applied the name Unio ellipticus in 1823 to a species which is believed to 
be Unio ligamentinus. Wagner placed this shell in the genus Unio in the text, but 
Spix called it Diplodon ellipticum in the plate. J therefore change the name to 
wagnerianum. Ihave never seen a shell that just agrees with his figure. It is near 
ethiopiformis von Ihering.

'Credited by Lea to Egypt, but no doubt a South American species, as it has 
regular radial beak sculpture and appears to belong with this group. 

2Dr. Lea believes that this shell came from Alabama, but it certainly did not. It 
‘is undoubtedly a Scuth American form. The type, the only shell I have seen is 
dead and in bad condition; but the beaks have radial sculpture, and I think it be- 
longs here. 

3No wide distinction exists between this and the preceding group, and there are 
species which might be assigned about as easily to one as the other. In general the 
forms of this division are more delicate, thinner, and more compressed than those of 
the Delodontus group. There are few clear characters in any of the species. Philippi 
and others have, it seems to me, unduly multiplied names for these forms, and the 
lack of suitable material and their extrere simplicity and similarity make it impos- 
sible for me to always determine which are valid. The synonymy is in bad shape, 
but I have done the best I could at straightening it out.

‘The type presented by Mrs. Mawe is not in the Lea collection, but there are 
fairly typical examples init. The species varies much in form and sculpture, some 
specimens being smooth, and all variations occur to those quite granose throughout. 
Lea places his species in the synonymy U. ellipticus Spix, which I think is an error. 
The type of multistriatus is more elongated than tke figure of U. granosus in the 
Encyclopedie Méthodique, but agrees very well with undoubted specimens cf this 
species which I have seen. 

2Credited by Kuster to Broun in litt. 

3Credited by Gould to Walla Walla, Oregon. Itis a young, rather smooth granosus 
I am sure, and the habitat given is wrong. The type isin the U.S. National Museum.

' Changed to lepidior because the name lepidus had been used for a Unio by Gould. 

2Only the briefest description is given of this in the index. From the figure it 
seems to be identical with chilensis. 

3 Generally credited to Swainson, and Philippi refers it to him with doubt. ButI

1Said by d@’Orbigny to be of Ferussac, but he does not say where that author 
described it, and I do not know where. This name has been used for at least four 
different species of Unionidw: As above; in Cuvier’s Animal Kingdom (edition with- 
out date); for Unie retusus, by Potiez and Michaud; and by Dr. Lea. I presume that 
WVOrbigny is entitled to the name. 

2Kuster credits this to ‘‘ Pfeiffer teste Charpentier.” Ido not know what it is. It 
is very different from d’Orbigny’s rhuacoica.

1 Sowerby’s name being preoccupied in Unio, I change it to cuprinus, which has 
not been used in Diplodon. The date, 1856 on the plate, is perhaps a typographical 
error for 1866. 

2The name auratus is preoccupied in Unio, by Philippi in the Conehyaicr: This 
being a different species, I change it to awreus.

Shell obovate to suborbicular, narrowed in front, produced just behind 
the center of the base, generally slightly pointed about the middle of 
the posterior end, with a scarcely perceptible posterior ridge and a 
slight dorsal wing behind; beaks high, irregularly radial; hinge line 


1 Only one specimen of this shell is reported, this being in the Wheatley collection, 
and credited to Texas. The beak sculpture is all eroded away, but I am almost sure 
it is a South American shell, allied, perhaps, to D. apprimus, wruguayensis, and possi- 
bly to Hupe’s Unio orbignyi.

Rio de la Plata. 


Subgenus HYRIDELLA Swainson, 1840. 


(Type, Unio australis Lamarck. ) 


Beaks rather low, sculpture consisting of curved, generally nodulous 
ridges, which approach below but usually have a smooth area of shell 
between them; surface sulcate or sometimes corrugated and nodulous; 
epidermis rayless; teeth rather delicate, compressed, often somewhat 
rudimentary. 

Animal having the embryos occupying the inner gills for the most 
part,? which are united for their entire length to the abdominal sac; 
outer gills pointed below in the middle; palpi triangular; branchial 
opening papillose; anal opening smooth, not separated from the super 
anal opening. 


Section HYRIDELLA Swainson, 1840, 


Shell covered with concentric, suleate sculpture; pseudocardinals 
well developed, compressed; laterals delicate, sometimes imperfect. 


(Group of Diplodon dorsuosus.) 


Shell somewhat rhomboid, inflated solid, with rather full beaks, the 
sculpture consisting of very strong, subradial, corrugated ridges which 
curve toward each other below, those in the center sometimes joining, 
this sculpture extending well out on the disk; upper part of pos- 
terior slope having slight radial folds. | 


‘T feel certain that Maton has illustrated two species, figs. 4, 6, and 7 being nearly 
circular, with a rather straight hinge, while fig. 5 is a small shell, is much inflated 
at the posterior base, and is incurved in front of the breaks. He describes the large 
shell first. The small one may be the young of D. patelloides. 

2 According to Suter in a letter.

1The name rugatus was applied previously to a European Unio by Rossmassler; 
but it may be used as a varietal name. This seems to be a smail form of menziezt 
which sometimes merges into hochstelleri. 

?Suter believes this to be only a pathologic form of menziezi. He says in a letter 
to the author that he has seen the same kind of disease among small rugatus.

‘Suter thinks this is a variety of menziezi, but Colenso states that the posterior 
slope is keeled. If this is so, it must be quite different from that species. 

?Lamarck’s description of this species is wholly inadequate, and would apply about 
equally well to several species. He refers to no figure, and Lea states that he did 
not see the type. I credit the species to Hanley, whose figure seems to represent a 
form of an abundant and variable species commonly referred to Lamarck.

2 Specimens received from Mr. Bednall bearing the above name are undoubtedly a

3The types are in the U. 8. National Museum collection. Lea believes it to be the 
same as the australis. Iam inclined to think it distinct.

1T can not identify Lamarck’s Unio depressus with any certainty from his very 
meager description. Lea believed it to equal the form I have considered as australis, 
but Lamarck’s description seems to apply to a more elongated species. Delessert’s 
figure in 1841 probably equals Lea’s paramattensis. As the name depressus was used 
for a Unio in 1801 by Donovan I am obliged to use another for this. 

2A specimen of this in the Lea collection from the Stuart expedition is identical 
with Lea’s species.

1 According to Dautzenberg the beaks of the remarkable species on which I have 
founded the above subgenus are completely smooth. It has the appearance of a 
Diplodon in all other respects, according to the figures and description. Dautzen- 
berg does not very carefully describe the teeth. 

2 According to d’Orbigny (Voy. Am. Mer., p.611), this species, which he says is the 
depressa of Lamarck, is found in Chile, near Valparaiso. It can not be Lamarck’s 
species.

Ido not know where the last five species are described, and they 
probably have never been published. Wright has named a Texan 
species. Unio theringi. 


Family MUTELID A. 


Shell usually without sculpture throughout; beaks smooth or but 
faintly corrugated, never exhibiting the remains of an embryonic shell; 
with or without teeth, which, when present, are irregularly taxodont, 
the shell showing vestiges of them in all the genera; nacre soft, richly 
tinted, generally surrounded with a wide, prismatic border; escutcheon 
large, distinct; palleal line usually simple, but sometimes having a 
slight sinus posteriorly. 

Animal having the labial palpi large, rounded below, generally with- 
out free points, scarcely or not at all united posteriorly; anal and 
superanal openings not separated; mantle generally closed behind into 
branchial and anal siphons, which are always separated by a strong 
bridge; marsupium occupying the inner gills; embryo a lasidium, com- 
posed of three segments, the anterior head-like, the median bearing 
a single shell, the posterior tail-like. 


Genus SAW TAs ean lS3s: 
(Type, Anodonta rubens Lamarck. ) 


Spatha Lea, Tr. Am. Phil. Soc., VI, 1858, p. 141, footnote. 


Shell elliptical; beaks very slightly or not at all sculptured; left 

valve having a faint, compressed tooth under and in front of the beak, 
which fits into a corresponding depression in the right valve; the 
entire hinge area often covered with longitudinally folded epidermal 
matter; escutcheon dark, sharply triangular; beak cavities shallow, 
with a single, elongate, deep scar in each; two large anterior muscle 
scars and two posterior ones, the upper small. 
- Animal having the palpi longer than wide, semicircular, attached 
along the upper edge, not united; mantle margin united behind so that 
the branchial and anal apertures are closed; on the under margin the 
mantle is entirely open; outer branchiz united to the mantle to their 
extremity; inner the larger, free from the abdominal sack; foot tongue 
shaped, thick; anal and branchial openings separated by a strong 
bridge. SS. rubens Lamarck (Troschel).

1Savigny’s plates were issued without explanation in 1813. In 1827 Audouin pub- 
lished an explanation of them. Von Martens believes this is not the Spatha rubens 
of the Encyc. Méth. (Mal. Bl., 1866). This species is widespread, abundant, and 
variable, and the material I have examined leads me to believe that it may include 
either the short, rounded form of the Encye. Méth. or specimens that are more 
elongated and even somewhat rhomboid. 

2T can not see any essential difference between this and forms of what I believe 
are S. rubens. I believe that the S. cailliaudi is only one of these forms. 

3I have only seen the reprint of this paper, which begins with page 1.

'T agree with Lea that this = exotica. The teeth are not strongly developed. 

*Gmelin refers to Adanson’s figure. Dillwyn evidently has Gmelin’s species and 
Cristaria plicata from China confounded. Two or three of these so-called species of 
Mutela are very close, and large series from different localities would probably show 
that they run together. There is much variation in the form and the develop- 
ment of hinge tubercles, even in a single species from a given locality.

Subgenus PSEUDOMUTELA Simpson, 1900. 
(Type, Mycetopus plicatus Sowerby.') 


Shell rather thin, elongate, wide, round and gaping behind, cut away 
and gaping at the anterior base; beaks low; surface rudely sulcate; a 
series of irregular nodulous projections extends down the low posterior 
ridge; hinge edentulous, with a kind of faint, broken internal ligament, 
with a wide prismatic streak behind; muscle sears distinct, united, the 
anterior protractor, however, separated and irregular; nacre lurid 
violet, iridescent behind.

1This is certainly not a Mycetopoda, but is evidently nearer Mutela than anything. 
Ihave placed it in that group as a subgenus, though it may be worthy of generic 
rank.

united their whole length to the mantle; inner united to the abdominal 
sac; genitalia occupying each side the lateral part of the visceral mass as 
far forward as the foot; mantle closed below the branchial siphon, and 
united into branchial and anal siphons; anal opening rather small; 
branchial opening large, the two separated by a solid bridge which solders 
together the extremities of the four branchiwe,; both orifices have a

Shell large, obovate, inflated, with a straight hinge line which is 
produced into a slight wing before and behind, tbe posterior end 
bluntly pointed and somewhat truncate above, with a faint posterior 
ridge; beaks full, smooth, epidermis olive, generally smooth; hinge 
edentulous; beak cavities rather shallow; dorsal scars small and 
numerous, running in a straight line from behind the beaks downward 
and forward; posterior muscle scars united, large; palleal line gen- 
erally showing a sinus.! 


' Conchologically this genus seems to be very closely related to Glabaris, especially 
to the group of G. trapesialis. Some of the shells of that genus have a slight dorsal 
wing in front and behind, and traces of a palleal sinus.

2The volume of the transactions in which Lea’s name was published was issued, 
according to Scudder, in August or September, 1834. Gray read the paper contain- 
ing the description of his Anodon parishii before the Zoological Society on July 8 of 
the same year, and the date of publication of that volume of the proceedings is 1834. 
As I do not know just when it appeared, and as Lea’s is the better known name, I 
retain the latter. 

3Gray states in a letter to Lea, November, 1834, that his 4. parishii and Lea’s 
blainvilliana are the same. 

4 According to Lea. I have not seen this paper. The species is quite commonly 
credited to Jan, but it was published by @Orbigny under the name of Jridina esula 
in 1835, and I am not aware that Jan described it earlier than 1837.

wide and well defined. 

Animal with the marsupium occupying the whole of the inner 
branchiz, which are united their entire length to the abdominal sac; 
palpi generally semicircular or kidney shaped; attached along their 
entire upper length, not projecting posteriorly; branchial and anal 
openings with or without papille, not united into siphons in the speci- 
mens examined, separated by a strong bridge; superanal opening not 
closed below. 


Section GLABARIS Gray, 1847 


(Type, Anodonta exotica Lamarck.) 


Shell rounded to elliptical; posterior ridge low or wanting. 
(Group of Glabaris patagonicus.) 


Shell solid, inflated, obovate, usually somewhat produced behind the 
center of the base; beaks quite full, projecting above the hinge line; 
epidermis olive brown, rather smooth, generally rayless; anterior muscle 
sears well defined. 

Animal with the gills large, rounded below; palpi rather large; 
mantle thickened at edge and furnished with palpi in front of the 
branchial opening; branchial opening large, with numerous minute 
papille; anal opening large, with no papille.

‘An old worn shell—the type—is the only one in the Lea collection, save a few 
very young that are doubtfully the same. It is a little more inflated than most 
specimens that are called lato-marginata, but not more than some are, and I hardly 
think it distinct.

1Tt is difficult to tell what this is, but I believe it to be some species of Glabaris, 
from the fact that Maton says that the hinge is edentulous. The figure (11) plainly 
shows it to be destitute of radial beak sculpture, though the umbo is perfect. The 
specimens figured are evidently young.

crispata. I think he is right. 

+The name subsinuata, applied to this by Philippi, will have to be placed in the 
synonymy, as Sowerby used it previously for a Glabaris which he placed in Anodonta,

1 This is briefly described in the index, p. 595, as Anodon susanne. In the text the 
genus is called Anodontites. 

2Two specimens of this, a large and a smaller one, are in the Gould collection. 
Lea places the species in the synonymy of G. trapesialis Lamarck., to which Lewis 
objects in a note on the back of Gould’s label on account of its locality—Mexico. 
After carefully comparing these shells with all our trapesialis in the Museum col- 
lections I am unable to separate the two. Carpenter states (Mazatlan Shells, p. 117) 
that it is found rather plentifully at Mazatlan. I do not believe that the locality 
given for Gould’s shells is correct (it is referred to Mexico with doubt by its author), 
and have no doubt that they are from South America. The species alluded to by 
Carpenter is probably G. glauca Valenciennes, which is closely related to G. trapesialis. 

3 Glabaris trapesialis is a very abundant, widely distributed species, and shows a 
great number of variations. Some of these are probably worthy of varietal names, 
others seem to be so mixed with various forms that they are scarcely worthy of any 
designation. 

‘A brownish, somewhat elongated form, much narrowed in front, receiving its 
name from having dark purplish letter-like marks on the nacre. There is every pos- 
sible development of this character from shells in which it is a marked feature to 
those without it at all.

\'The above atrocity, which is a sample of many names in Petel, is no doubt 
intended for G. grijalva. 

2 Sowerby gives two figures of what he calls ciconia, 115a being most likely a young 
shell of some form of trapesialis, the other a totally different form, apparently a new 
species of Glabaris of the trapesialis group. As far as the figure shows it may be 
described as follows: Shell subquadrate with nearly straight dorsal and basal lines, 
biangulate behind, greatly inflated, with very full, high beaks which rise far above 
the dorsal line, winged and angulated at the front and hinder dorsal line; color 
olive-green. Length, 147mm.; height, 92 mm.; elevation of beaks above dorsal line, 
10 mm.

! Probably only a variety of tenebricosus. 

2 Fischer changed the name plicatus to clessini because the former name had been 
used by Sowerby for a species which he (Sowerby) placed in Mycetopus. Sowerby’s 
shell is a Mutela, and that of Clessin a Glabaris of the Tenebricosus group. Von 
Ihering applied the name nehringi to the above after Fischer had changed it, and 
was evidently not aware that the French savant had given it a new name.

(Type, Glabaris ensiformis Spix.) 

Shell subsolid to solid, moderately inflated, greatly elongated, straight 
or faleate, rounded in front, sharply pointed at the posterior base, 
where the high, sharply defined posterior ridge ends and above which 
it is somewhat obliquely truncated; beaks not high; epidermis green 
to olive; nacre brilliant, bluish or purplish, iridescent, rayed with very 
fine, indistinct ridges; posterior end with a slight sinus. 

Animal unknown. 


‘Valenciennes gives no name or description with the above, but the figure is, no 
doubt, G. obtusa. 

2Hupe is certain that this is different from obtusus, and says that the small angular 
marks on its surface are very distinct; that it is thinner and less inflated. I doubt 
whether it is more than a variety of obtusus.

‘The three very peculiar species of this section seem to show relationship with G. 
wheatleyt and G. clessini. 

2 Shell elongated, rather thin, subrhomboid and pointed at the posterior base, 
slightly rayed on the low, rounded posterior ridge; beaks low; epidermis olive 
green, somewhat cloth-like; hinge line nearly straight; anterior scars deep; 
escutcheon small, dark; nacre shaded bluish and greenish, lurid purplish in the 
center, iridescent behind. Length, 76 mm.; height, 21 mm.; diameter, 11 mm. 
This was supposed by Dr. Lea to be ensiformis and I thought it was that until a 
more careful examination convinced me of its distinctness. It is a smaller, thinner, 
more rhomboid sheil, and has a somewhat cloth-like epidermis, while that of ensi- 
formis is smooth. I regret that I can not figure this species, and that I must describe 
it in a footnote, but I only discovered that it was a distinct species as the Synopsis. 
was about ready for the press. 

3T can not tell what thisis. If itis a true Glabaris, it would be the type of a 
group perhaps near G. tenebricosus. 

+D’Orbigny refexs to figures in Spix, but his references are badly mixed up.

Genus MYCETOPODA dQ Orbigny, 18385.! 
(Type, Mycetopoda soleniformis VOrbigny. ) 


Mycetopoda D’ORBIGNY, Guer. Mag., No. 62, 1835, p. 41. 
Mycetopus D’ORBIGNY, Voy. Am. Mer., 1847, p. 600. 


Shell thin, elongated, truncate above behind, with a low, posterior 
ridge and rather flat, smooth or slightly concentrically wrinkled beaks; 
epidermis smooth, shining, pale greenish-yellow or brownish, rayless; 
hinge line long, straight, edentulous orshowing faint traces of denticles, 
under a glass, beneath the nacre; nacre soft, bluish-white and irides- 
cent; muscular impressions faint, irregular, the smaller anterior scar 
above the larger one; beak cavities shallow. 

Animal having very long gills, the inner much the larger, united to 
the abdominal sac throughout their whole length; palpi large, round 
below, projecting very slightly behind and attached along the whole 
length of the straight upper border; mantle very thin, slightly thick- 
ened at the edges; branchial opening closed below into a short papillose 
Siphon, and separated from the nearly smooth anal opening by a strong 
bridge; superanal opening not closed below; foot very long, developed 
at the lower end into a sort of head or button. 


‘So named by its author in the Guerin Magazine, but afterwards changed by him 
to Mycetopus in the Voyage Amerique Meridionale. The genus has been made the 
type of a separate family by Gill, and was so acknowledged by Pelseneer and. others, 
but it does not seem to me to be separable from the Mutelidw. Certain shells under 
favorable light show slight dentilations along the hinge line, which are, no doubt, 
vestigial taxodont teeth common to the family; the labial palpi and anal bridge are 
decidedly mutelid in character, and the great development of the foot is paralleled 
in Solenaia, Lastena, and to some extent by Gonidea among the Unionidae.
