CRITICAL NOTES ON THE TYPES OF LITTLE-KNOWN
SPECIES OP NEOTROPICAL BIRDS.— PART II.*

BY C. E. HELLMAYK

IN the following lines I propose to discuss another series of type-specimens
which I have had the opportunity of examining during the last six years,
and it is hoped that these notes may not be devoid of interest to the student of
neotropical ornithology. Acknowledgments for the loan of material are dne to
the same gentlemen as mentioned in the first part of this paper, and also to Dr.
J. A. Allen, Mr. 0. Bangs, Dr. Hans Gadow, and Mr. F. V. McDonnell.

48. Thryothorus coraya and allies.

Among South American Wrens this is unquestionably the most puzzling and
most difficult group. It embraces seven or eight races which, although sometimes
separated by wide tracts of country, differ one from another only in slight, but
fairly constant characters. For a long time the typical T. coraya, " Le Coraya de
Cayenne " of Buffon and Daubenton, was the only recognised form whose range
was supposed to extend over nearly the whole Amazonian subregion from French
Guiana to the eastern slopes of the Andes in Ecuador and Peru. The first attempt
to discriminate local races of this wide-ranging bird was made by the late
R. B. Sharpe, who, in 1881, described Thryothorus amazonicm from the Ucayali,
and T. griseipectus from the north bank of the Marailon.f In 1903 the present
writer J gave a short review of the known forms, which, in the light of the
ample material now at hand, requires considerable modification. Quite recently
Lord Brabourne and Mr. Chubb § have dealt with the Guianan representatives of
the group, but being unfamiliar with the variation of these birds, and unacquainted
with the existing literature, they have fallen into several errors, and added,
furthermore, to the confusion by creating two useless synonyms. || So much about
the previous papers relating to the subject.

The careful study of a large series leaves no doubt that T. coraya, T, ridgwayi,
T. amazonicus, T. griseipectus, T. griseipectus caurensis, T. herberti, and T. cantator
are merely representatives of the same specific type, agreeing with one another in
all essential points, and replacing each other geographically. It is probable that
T. albicentris Tacz. H also belongs to this group ; unfortunately I have not been able
to secure an example of this rare species.

The total of specimens examined in the present connection amounts to seventy-
two — certainly a far greater number than has yet been at the disposition of any

to T. major semifasciatus (Cab.), which has a wide range in northern South America.

monographer. Before proceeding to the account of the various races it may be
stated that adult males and females do not differ in coloration ; the latter are,
however, smaller, and have a shorter, slenderer bill. Young birds of both sexes
are much more brownish beneath, the white markings on the sides of the head
are dingy, ill-defined, sometimes even obsolete, the upper parts duller as well as
darker, etc.

T. oyapocensis oyapocensis Brabourne & Chubb, Ann. Mag. Nat. Hist. (8) x. 1912, p. 262 (French

Hob. French Guiana : Cayenne, Ipousin, Appronague (Cherrie), Oyapoc
(Jelski), Saint-Jean-du-Maroni (Le Moult) ; Surinam : near Paramaribo (Chunkoo).
North Brazil : Barra do Rio Negro [= Manaos] (Natterer).

Adult. — Upper parts rufous brown, duller on crown and nape ; upper tail-
coverts dull rufescent brown, either uniform or with traces of dusky cross-lines ;
rectrices regularly barred with blackish and greyish brown or dingy grey, the light
bars towards the base of the tail often slightly tinged with fulvous. Sides of
head and neck black, varied with numerous well-defined white shaft-stripes ;
a very distinct superciliary line white. Below : throat and foreneck white, the
latter tinged with pale greyish ; middle of breast and abdomen dull greyish white
or dingy buffish, chest clouded with brownish ; sides of the body extensively
fulvous-brown ; under tail-coverts somewhat paler, barred with dusky.

Juv. — Differ by having the sides of the head sooty blackish with obsolete,
greyish white markings ; the crown and nape brighter rufous brown ; the throat
more greyish, the foreneck smoky grey, and the remainder of the under parts nearly
uniform fulvous brown, there being but a few buffy white feathers in the middle
of the breast. The basal half of the lower mandible is bright yellow, abruptly
defined against the blackish tip, while in adult birds the under bill is wholly
horn-grey.

Material. — 1 c? ad. Barra do Rio Negro, 10 from French Guiana, 1 imm. from
Surinam. Specimens from different localities average as follows :

Four adult males from Cayenne (French

Guiana). . . ' . . . Wing 59-61 ; tail 53-56 ; bill 17-18 mm.
One adult male from Barra do Rio Negro,

Brazil Wing 62 ; tail 57 ; bill 16 mm.

One adult female from Cayenne . . Wing 58 ; tail 53 ; bill 17 mm.

One immature (not sexed) from Surinam Wing 59 ; tail 57 ; bill 15| mm.

Observations. — The series from Cayenne and Surinam is fairly uniform. An
adult male from Saint-Jean-du-Maroni is rather lighter rufous on the back,
approaching T. c. amazonicus, though otherwise it is quite typical. The single

( 229 )

Brazilian specimen, a perfectly adult male, agrees in every way with Cayenne skins
and belongs undoubtedly to the present race. It is one of the two examples
referred to as T. coraya herberti Ridgw. in my paper quoted above. How this
mistake could have been committed I am at a loss to understand. In fact, the
Manaos specimen differs from that taken at Cara-raucu (which will be discussed
later on) by much darker, more chestnut-brown upper parts, dingy grey (instead
of cinnamon-brown) tail, more extended as well as much brighter fulvous-brown
colour on the sides of the body, distinct white markings on the cheeks and ear-
coverts, and by having the chest clouded with brownish. In all these characters
it is practically identical with Cayenne examples. T. c. coraya ranges, therefore,
from French Guiana south to the north bank of the Amazons.

Nomenclature. — Messrs. Brabourne and Chubb accept for the Cayenne bird
the name T. oyapocensis Ridgw., under the assumption that Daubenton's plate
represents the race from the Roraima Mountains in British Guiana. However, this
view cannot be upheld for several reasons. Firstly, on reference to Buffon's work *
we find that the description of " Le Coraya " f evidently applies to the ordinary
Cayenne bird, which, moreover, is the only Wren of this group occurring in the
French colony. Secondly, the interior of British Guiana was literally unknown at
the time of Buffon's writing ; and it was not until 1842 that Richard Schomburgk,
as the tirst European traveller, reached the distant mountain chain of which
Roraima is the culminating peak. Daubenton's figure with uniform fulvous -brown
belly might well have been taken from a young bird in which, as said above, the
greyish white middle line is nearly wanting.

Adult. — Much like T. coraya coraya, but differs by having the under parts
(except throat and foreneck) strongly washed with ochreous brown or tawny
ochraceous. In all other characters, viz. rufous brown colour of upper parts, greyish
brown tail-bands, distinct white stripes on sides of head, etc., it closely resembles
the typical race.

Juv. — Breast and abdomen uniform rufous-brown, much darker than in the
corresponding stage of T. c. coraya.

(Camacusa, Roraima) . . . Wing 55-57 ; tail 52-57 ; bill 15 mm.

Observations. — Messrs. Brabourne and Chubb, in the paper quoted above,
distinguish three races as occurring in British Guiana under the names of
T. coraya coraya (Roraima), T. c. berlepschi (Bartica Grove), and T. oyapocensis
ituribisciensis (Ituribisce district). Mr. F. V. McConnell very kindly forwarded
for my inspection his entire series of Wrens which had formed the basis of their
conclusions. This material, supplemented by the specimens in the Munich, Tring
and Berlepsch Collections, and including the types of T. ridgwayi, T. berlepschi, and
T. o. ituribisciensis I have carefully studied, with the result that I find there exists in
British Guiana but one form, which is entitled to the name T. c. griseigula (Lawr.).
Let us first consider the inhabitants of the lowland districts, which, according
to Brabourne and Chubb, are referable to two races, one with dull fulvous under-
parts (T. c. berlepschi), the other with greyish middle line ( T. o. ituribisciensis).
On comparing fifteen specimens I notice that three from Bartica Grove
(including the types of T. ridgwayi and T. berlepschi), and an adult male from
Supernaam are much the darkest, the under parts posterior to the white throat and
foreneck being nearly uniform bright tawny ochraceous. Then follow two skins
from the " Great Falls " and Camacabra Creek with a somewhat duller, more
brownish ochraceous belly, which in the last-named bird passes into a paler, more
brownish buff tinge along the middle line. Next come two males from Ituribisce
(one the type of T. o. ituribisciensis) in which the under parts are mainly buffy brown,
darkening to ochreous brown on the flanks. An adult bird from Supernaam is
closely similar, but the middle of the abdomen is rather more greyish brown and
the sides are decidedly darker. Finally, two males (adult and immature) from
Supernaam and Ituribisce are even more greyish in the middle, and, except for the
slightly darker sides, they are not distinguishable from average Cayenne specimens,
i.e. T. c. coraya. From the above, it will be seen that the variation is purely
individual and not connected with any particular geographic area. It should also
be borne in mind that the Ituribisce is in the same district as the Snpernaam, both
rivers draining their waters through the plains into St. James' Canal (mouth of
the Essequibo). The conditions for the development of a peculiar form are, therefore,
hardly given.

Messrs. Brabourue and Chubb, furthermore, consider the birds from the moun-
tainous interior (Roraima) to be distinguishable by their lighter " chestnut " back
and brighter fulvous underparts. The majority of my skins from the mountains
are indeed of a clearer ochraceous beneath, but several are not different from the
type of T. ridgwayi (ex Bartica Grove), whereas a male from the Carimang River
(Roraima district), in the dull ochreous-brown belly, exactly matches some of the

( 231 )

lowland examples. In the shade of the upper parts I cannot discover any constant
difference between the two series. Adult Roraima birds are by no means lighter
rufous brown than those from Bartica Grove or Supernaam, and for the present I am
unable to discriminate more than one form in British Guiana.

Thus, T. c. griseigula may be characterised as being similar to T. c. coraya,
but as a rule easily distinguishable by the ochraceous or ochreous brown colour
of the lower parts, though occasionally specimens may be found which closely
resemble the typical race.

Nomenclature. — The earliest available name is apparently Formiciwra
griseigula, founded upon an immature example from British Guiana. The de-
scription leaves no doubt as to its identity, which, moreover, has been confirmed by
Dr. J. A. Allen through examination of the type specimen.

3. Thryothorus coraya herberti Ridgw.

Thryothorus herberti (Hiker MS.) Ridgway, Proc. U.S. Mus. x. 1887, p. 516 (1888.— Diamantina,

near Santarem, Lower Amazons) ; Chapman and Riker, Auk, vii. 1890, p. 266 (Diamantina).
T. coraya herberti Hellmayr, Journ.f. Orn. 51. 1903, p. 533 (part.: Cara-raucu).
T. coraya (errore) Pelzeln, Zur Orn. Bras. i. p. 48 (part : Cara-raucu, Lower Amazons).

Hab. — North Brazil, south bank of the Lower Amazons : Diamantina, near
Santarem (Riker), Cara-raucu (Natterer).

Adult. — Nearest to T. coraya coraya, from Cayenne and Manaos, but differs
by having the sides of the head almost uniform black (relieved only by a very
narrow, inconspicuous, white superciliary streak and a few extremely narrow lines
of the same on auriculars) ; the upper parts much brighter, more chestnut rufous ;
the light tail-bands cinnamon-brown instead of dull greyish ; the foreneck and
chest more purely buffy grey without brownish suffusion ; and the flanks less
extensively as also paler rufescent brown.

Material. — One <£ ad. from Cara-raucu, Lower Amazons, J. Natterer coll.,
Vienna Museum. Wing 62 ; tail 58 ; bill 16 J mm.

Observations. — This specimen agrees very well with Mr. Ridgway's description,
and appears to be decidedly distinct from T. c. coraya. The pileum and nape are
dull sepia brown, slightly tinged with umber or rufescent, the remaining upper
parts, including wing- and tail-coverts, bright chestnut rufous. Underneath it
resembles the Cayenne form, but the breast is somewhat paler and lacks the
brownish suffusion, while the flanks are lighter brown. There is, however, no
difference between the two races either in size or in the shape of the bill. From
T. coraya amazonicus, of Upper Amazonia, T. c. herberti may be distinguished by
the reduction of the white markings on sides of head, by the cinnamon-brown
(instead of dull greyish) tail-bands and by the bright chestnut-rufous upper parts.
Seen from below the two races are perfectly alike.

Hab. — Northern Peru, south of the Maraiion : Sarayagu, Ucayali R. (Bartlett) ;
Yurimaguas, Huallaga R. (Stolzmann, Garlepp).

Adult. — Much like T. c. coraya, and only distinguishable by its lighter, rufous-
brown upper parts and less rufescent-brown flanks. The bill is by no means

( 232 )

stronger than in adult birds of T. c. coraya^ and the dusky barring of the upper
tail-coverts upon which Dr. Sharpe and Count Berlepsch laid much stress is not a
constant feature either. The light-coloured tail-bands are dingy greyish or ashy,
only the basal ones slightly tinged with fulvous, exactly as in T. c. coraya, with
which T. c. amazonicus also agrees in having a very distinct superciliary stripe and
numerous white longitudinal streaks on the ear-coverts.

Material. — 1 c?, 1 <? imm. from Sarayac.u, Bartlett coll., in British (type) and
Tring Museums ; 1 cT ad. Yurimaguas, G. Garlepp coll., Mus. H. v. Berlepsch.

Two males from Sarayacu . . . Wing 69,61 ; tail 61,51 ; bill 18,17| mm.
One male from Yurimaguas . . . Wing 62 ; tail 56 ; bill 17£ mm.

Observations. — The type (from Sarayacu) and the Yurimaguas specimen have
the foreneck and chest pale greyish white, clouded with brownish (like T. c. coraya),
while the second (immature) male from the Ucayali shows a distinct buff wash all
over the middle of the belly. The upper tail-coverts are nearly uniform rufous-
brown in the Yurimaguas bird, but strongly barred with blackish in the two
Sarayagu skins.

5. Thryothorus cor ay a cantator Tacz.

Thryothorus cantator Taczanowski, Proc. Zool. Soc. Land. 1874, p. 130 (1874. — Amable Maria,

P.Z.S. 1896, p. 328 (La Merced, La Gloria, Central Peru ; two ? $ ).

Hab. — Central Peru, dept. Junin : Amable Maria (Jelski), La Merced, La
Gloria (Kalinowski), Chanchamayo (Schunke).

Adult. — Differs from T. coraya amazonicus by lacking the white streaks on
sides of head, and by having the tail-bands bright cinnamon-brown (instead of dull
ashy or brownish grey). The white superciliary stripe is barely indicated by a
few minute, obsolete lines above the auricular region.

Material. — 1 cT ad., 1 ? imm. from Chanchamayo, obtained by Mr. C. 0.
Schunke in February 1909, in the Zoological Museum of Munich.
<? ad. Wing 65 ; tail 56 ; bill 15 mm.
? imm. Wing 64 ; tail 57 J ; bill 16 mm.

Observations. — The two specimens agree in general coloration with the pre-
ceding race. The back and outer margins of the remiges show exactly the
same light (cinnamon) rufous-brown tinge ; the foreneck is pale greyish buff,
passing into a purer buffy along the middle of the abdomen ; the sides are clear
fulvous brown. From T. coraya herberti they may be distinguished by the much
paler rufous upper parts and flanks, as also by the greater reduction of the white
markings on the " mask," the auriculars being quite uniform blackish and the
superciliary line barely visible.

Rio Negro district : Marabitanas, R. Icanna, between S. Isabel and Castanheiro
(Natterer).

Adult. — Differs from T. c. coraya and T. c. amazonicus by much darker chestnut-
brown upper parts ; pale fulvous (instead of greyish brown) tail-bands ; by having
the lower surface posterior to the throat distinctly ashy grey, without any brownish
suffusion on the chest, the sides of the body alone being dark russet brown. Size
generally less, especially the bill weaker and slenderer.

Wing 58-61 ; tail 50-55 ; bill 15-16 mm.

Wing 57 ; tail 47 ; bill 14|-15 mm.

Observations. — The typical Peruvian birds when compared with a series from
Cayenne are much deeper, chestnut brown above, and have the median p6rtion of the
breast and abdomen more decidedly ashy grey, the chest being by no means clouded
or washed with brownish. The sides of the belly are extensively and dark rufous
brown, as in T. c. coraya, but the upper tail-coverts are much darker, without traces
of dusky barring. There is a very distinct white superciliary stripe, also the sides
of the head are strongly streaked with white. Birds from Eastern Ecuador are
practically identical with the Peruvian ones. The series from the Rio Negro, how-
ever, differ slightly : they are smaller, with the bill notably so, and the upper parts
are still deeper chestnut brown. In the small size they agree with T. c. caurensis,
but have much more rufous-brown on the flanks. In a previous communication on
this subject I have referred them to T. c. coraya, from which they are, however,
obviously distinct.

All the above examples are distinguished by having the tail-bands light
fulvous (that is, neither bright cinnamon as in T. c. herberti, nor dull greyish
brown as in T. c. coraya). The upper mandible is black, the lower one horn-grey
with light tip.

Caura River, East Venezuela).

Hal). Eastern Venezuela, Caura Valley : Nicare, La Pricion (E. Andre').

(234 )

Adult. — Agrees in all essential characters with T. c. griseipectus, but the
whole of the lower parts (except throat) is ashy grey, only the innermost sides
of the belly being much paler russet-brown.

Material. — 8 c?c?, 4 ? ? from the Caura (including the type), six in the
Munich, five in the Tring Museum.

Eight males Wing 61-64 ; tail 50-55 ; bill 16J-18 mm.

Four females Wing 56-58 ; tail 45-49 ; bill 15-16 mm.

Observations. — I am not very confident as to the distinctness of this form,
which additional material from intervening countries may prove to be inseparable
from T. c. griseipectus, although the twelve Caura specimens have certainly less
rnfescent-brown suffusion on the flanks. The alleged difference in the colour of
the lower mandible does not exist. The original describers were deceived by the
defective state of the Nauta specimens, all of which had lost the corneous tegument
of the bill. In fresh skins from Peru and Ecuador the under mandible is horny

Wing 79 ; tail 67 ; bill 17 mm.

The careful comparison of the type specimen with a large series from Colombia,
(Bogota, Antioquia) and Ecuador proves it to be a very young example of C. nigri-
rostris. Unmistakable signs of immaturity are the pale cinnamon tips to the
greater upper wing-coverts, the pointed rectrices, and the peculiar texture of the
feathers on the flanks and crissum. Moreover, the pileum is still covered with
the characteristic, fluffy, dull reddish cinnamon feathers of the nestling, which
extend, in a wide stripe, over the temporal region to the sides of the nape. Dr.
Sclater mistook these stripes for " superciliaries," while, in fact, they are but
remains of the juvenile plumage. The real superciliary streak, indicated by several
dark chestnut feathers, is by no means more extended than in average specimens of
C. nigrirostris, reaching as far as the posterior border of the eye. Newly-grown
feathers that are to be observed here and there between the rufous ones have
exactly the same colour as in adult C. nigrirostris, being cinereous on the forehead,
bright green on the crown and temporal region. The coloration of the under parts
agrees minutely with that of adult birds, except that the inner margin of the
remiges is somewhat brighter yellow. The bill lacks the abruptly defined pale
basal spot, the corresponding portion of the mandible being dark brown, but
slightly lighter than the black apical half. An immature Bogota skin in the
Munich Museum is intermediate in that respect.

C. atrirostris must, therefore, be relegated to the synonymy of C. nigrirostris,
since constant differences between Ecuadorian and Colombian specimens do not
appear to exist. Generally birds from Bogota and Eastern Ecuador (Baeza) have
rather smaller bills than those from Western Ecuador (Gualea, Milligalli), but there
are numerous exceptions to these rales. In coloration they are perfectly alike.
Specimens from different localities average as follows :

This specimen is, without doubt, a female of M. s. sanctae-martae , and agrees in
every particular with an example from Los Palmales, Andes of Cumana (Bermudez,
N.E. Venezuela) in the Tring Museum. In both, the lower surface of the body is
dull ochraceous, darkening to brownish on the sides, but the type has the throat of
a rather brighter tinge. The forehead, lores and sides of face are conspicuously
washed with ochreous, the back is greyish olive, the wing-coverts and remiges are
edged with olive-brown, exactly as in the Venezuelan bird. The maxilla is
blackish, the mandible dingy horny whitish.

Venezuelan specimens measure as follows: wing 56-58| ; tail 39-42; bill
13-14 mm. Thus, it will be seen that there is no difference in size either.

M. schisticolor sanctae-martae is as yet only known from the Caribbean Coast-
mountains of Venezuela and Colombia. Cfr. Hellmayr and Seilern, Archiv f.

This bird is practically identical with the type in the British Museum and two
others from the same district at Tring. The wing varies from 61 to 64, the tail
measures 60, the bill 15 mm. None of the specimens being sexed, I cannot say
whether there is any sexual difference in size, but as far as coloration is concerned
the four skins* agree very well together.

B. griseiceps appears to be most nearly allied to B. leucoblepkarus, from
Southern Brazil and Paraguay. In both species, the crown and nape are dark

* I am not aware of the existence of other specimens than the above.

( 236 )

cinereous, the sides of the head are exactly alike, and the legs pale fleshy brown.
The Venezuelan bird differs, however, at a glance by the deep yellow (instead of
white) under parts.

Chlorospingus reyi Berl. * bears a remarkable likeness to B. griseiceps, but
may be distinguished by its less depressed, more curved bill, by the absence of
rictal bristles, by lacking the blackish mixture about the forehead, the white snpra-
loral streak and chin-spot, as well as by having the sides of the head olive-yellow
(not cinereous). There are two specimens of this rare species in the Tring Mnseam :
an adult female from El Escorial, February 20, 1896, and an adult bird from
M6rida, without date and sex, obtained by S. B rice no.

52. Chlorospingus flaviventris Scl.== Tachyphonus luctuosus Lafr. & D'Orb. ?ad.

Tachyphonus luctuosus Lafresnaye & D'Orbigny, Syn. Av. i. in : Mag. Zool. 1837, cl. ii. p. 29

(1837. — Guarayos, Bolivia).
Chlorospingus flaviventris Sclater, P, Z. S. Lond. xxiv. 1856 p. 91 (July 1856. — Trinidad [Mus.

Jardine] ; Bolivia ? [Mus. Strickland] ).

There has been considerable uncertainty about the name C. jlaviventris, which
was originally based upon two specimens : one from Trinidad in Sir William
Jardine's possession, and another supposed to be from Bolivia in the Strickland
Collection. The former is apparently lost, it being neither in the British nor in
the Tring Museum, while the second example is still preserved in the Cambridge
Museum, whence it has been kindly forwarded for my inspection by Dr. Hans
Gadow. It is a skin in good condition, labelled as follows : " Coll. H. E.
Strickland, No. 943 b. Tachyphonus luctuosus, Catalogue p. 194." The inscription
(in Strickland's own handwriting) of the old label reads: "Arremon-Chlorospingus.
Hab. Brazil ? Date 1852. Obtd. from Argent," and on the back : " C. Jlaviventris
new. Arremon No. 107 a."

Its dimensions are : wing 63 ; tail 57| ; bill 12| mm.

This example, which answers exactly to Sclater's original description, agrees with
several females of T. luctuosus from Bolivia, except in being slightly larger, with
a somewhat longer, slenderer bill, and in having the crown rather clearer cinereous.
These insignificant differences are no doubt individual. It appears to be one of
Bridges' skins, showing the same handsome " make-up " as several Bolivian
specimens, obtained by that traveller, in the British Museum.

Salviu f identified C. Jlaviventris with C. albitempora Lafr., considering No.
956 a of the Strickland Collection as the specimen referred to by Dr. Sclater.
Dr. Gadow having obligingly sent me the bird in question, J I can positively state
that this is a mistake. Dr. Sclater says of G. Jlaviventris : " capite cinereo, viridi
paulum apparente " and " gula albescenti-cinerea, abdomine toto flavo " ; whereas
No. 956 a has the top and sides of the head dark coffee-brown, the throat bright
isabelline, and the whole middle of the belly white, the flanks only being dull
yellowish olive-green ! It is, therefore, evident that No. 956 a cannot have been one
of the types of C. Jtaviventris. But it does not belong to C. albitempora, either,
differing by its isabelline (not whitish) throat, more buffy yellow chest-band, and
paler, less blackish crown. In all these particulars it closely resembles the type
of C. fulvigularis Berl., § forwarded for examination by my friend Count Berlepsch,

* Ibis (6) iii. p. 288 (1885.— M6rida, Western Venezuela),
f Catalogue of the Strickland Collection, Cambridge, 1882, p. 196.

j It is inscribed as follows: " Chi. albitempora, Catalogue p. 196, No. 956 a." On the old Strickland
label we read : "Brazil ? 1852. Obtd. from Argent. New 1 Chlorospingus — proposed to befnlvigularis."

( 237 )

and unquestionably refers to the same species. The preparation of the skin is that
of Bridges' Bolivian specimens.

C. Jlaviventris must, accordingly, be added to the synonymy of Tachyphonus
luctuosus (Lafr. & D'Orb.).

Wing 53 ; tail 43 ; bill 9£ mm.

This specimen agrees exactly with the original description, save in the
total length, which is only 11| cm., instead of 12| as given by Lafresnaye and
D'Orbigny. In coloration of the upper parts it closely resembles an adult
male from Vina, Maranon, North Peru, in the Tring Museum. The pileum and
back are light brown, with a hardly perceptible olive tinge, but the upper
tail-coverts are somewhat duller, and the rufescent edges to the median and
greater wing-coverts so conspicuous in the Vina bird are barely indicated in the
type specimen. The throat and foreneck (still covered with the fluffy feathers
of the juvenile plumage) are decidedly darker than in adults of S. obscura, being
dingy smoky brownish, with the greyish basal portion showing through. The
sides of the body appear to be slightly brighter fulvous brown, while the upper
mandible is somewhat paler horny brown.

These small differences are, no doubt, due to immaturity, and I think there
can be no question that E. obscura is merely a young bird of the species called
S. obscura nearly forty years afterwards. Structure and general style of coloration
are exactly the same as in a considerable series of the last-named species. Seen
from below, the type bears a certain likeness to the female of Tiaris faliginosa
(Wied),* but may be easily distinguished by having the middle of the belly
extensively white and the inner margin to the remiges rufous-buff (instead of
whitish), by its shorter tail, as also by its much smaller, less convex bill.

On comparing twelve adult specimens from various localities (2 Bolivia ;
1 Callacate, N.W. Peru; 4 Marafion, N.E. Peru; 4 Chimbo, S.W. Ecuador;
1 Paramba, N.W. Ecuador), I fail to see any differences connected with geographical
distribution, and can no longer recognise the northern form S. obscura pauper
(Berl. and Tacz.).f At all events, birds from N.E. Peru which are certainly
S. obscura Tacz. cannot be distinguished from the Bolivian ones. | S. obscura
Tacz. becomes, therefore, a strict synonym of Emberiza obscura Lafr. & D'Orb.

One £ ad., Paramba, N.W. Ecuador .... Wing 54; tail 41 J bill 9 mm.

( 238 )

This species is evidently out of place in the genus Sporophila, and seems best
referred — for the present at least — to Catamenia, although its bill, in comparison
to C. analis, is laterally much more compressed, with the cnlmen slightly ridged
instead of being distinctly rounded. The upper mandible, however, is very nearly
as depressed as in C. analis.

C. obscura (Lair. & D'Orb.) ranges from N.W. Argentine (Salta) through
Eastern Bolivia (Chiquitos, Santa Cruz de la Sierra, Omeja) and Peru (Paltay-
pampa, Tarapoto, Vina, Huamachuco, Callacate) to Western Ecuador (Chimbo,
Cayandeled, Paramba).

Wing 68 ; tail 66 ; bill 12 mm.

This specimen, which is undoubtedly the type of Bonaparte's description,
belongs to the species commonly called P. assimilis Cab., and agrees pretty well with
a c? ad. from Sao Lourenco, Rio Grande do Sul, H. von Ihering coll. in the Paris
Museum. But being in rather fresher plumage, it is everywhere brighter,
the mantle more decidedly brownish, the upper part of the head washed with
olive-grey, etc. Above the eye and auricular region there is a broad white
superciliary stripe ; throat and foreneck are pale greyish buff, middle of breast
and abdomen largely white ; sides of body and crissum, as also the whole of the
lower rump, including the upper tail-coverts, bright cinnamon-rufous ; only the two
outermost pairs of rectrices tipped with white, etc.

Bonaparte's name having priority must supersede the term assimilis Cab.
Cabanis' statement that P. cabanisi is well characterised by lacking the rufous
colour on the rump. I am unable to understand, for Bonaparte in the original
description expressly says : " uropygio, lateribus crissoque fulvo-castaneis."

P. cabanisi Bonap. ranges from southern Sao Paulo (Ytarare), through Parana
and Rio Grande do Sul to Paraguay and the Argentine provinces of Misiones and
Entrerios.*

Bp. Type, du Bre'sil, par M. Auguste Saint-Hilaire, aout 1822."

Wing 81, tail 84, bill 17 J mm.

This is quite a young bird, mostly covered with the fluffy feathers of the
nestling plumage ; only on the shoulders (lesser wing-coverts) and here and there
on the back some isolated feathers of the adult dress are just C" 'ing out. The
large, thickish bill, and the strong legs with long toes, leave no ,oubt as to its
being a pullus of Embernagra platensis.

* I have examined fourteen specimens from the following localities : 2 ( ^ $ ) Ytarare, S. Paulo ;
4 (2 cf , 2 ?) Roca Nova, Sena do Mar, Parana ; 1 £ Campo Largo, Parana; G Bio Grande do Sul
(Taquara do Mundo Novo, Sao Lourenco, Arroio Grande) ; 1 <-£ La Soledad, Entrerios.

( 239 )

The concealed basal portions of the rectrices are pale green, the anal region
and under tail-coverts bright buff , as in adult specimens from Barracas al Sud
(Buenos Aires), while the newly-grown lesser wing-coverts show exactly the same
yellowish green tinge.

In other respects the type fairly agrees with Dr. Sharpe's * description of the
young of E. platensis. The top of the head aad back are buffy brown, broadly striped
with blackish brown ; the median and greater wing-coverts dusky, with whity-
brown edges ; the outer margins to the remiges duller green than in the adult ; the
under surface is whitish (instead of olive-grey), with distinct reddish brown shaft-
streaks on foreneck, breast, and flanks. Perfectly adult birds of E. platensis have
no traces of dusky markings underneath, but in immature examples there are
sometimes dark brown streaks on the foreneck to be seen.

The upper mandible, in the type specimen, is blackish brown, the cutting-edges
yellowish brown, the lower mandible whitish.

Emberizoides megarhyncha Bp. is, thus, to be added to the synonyms of
E. platensis. Dr. Sharpe * had doubtfully referred the name to Emberizoides
herbicola (Vieill.).

56. On Empidochanes poecilocercus Pelz. and Knipolegus pusillus

Scl. & Salv.

In the second part of his well-known Zur Ornithologie Brasiliens the late
August von Pelzeln described as a new species Empidochanes poecilocercus from a
single female example, obtained by the celebrated traveller J. Natterer on the
Arnajau, one of the tributaries of the Rio Negro. The species was not mentioned
again in ornithological literature until Berlepsch and Hellmayr,j- from an examina-
tion of the type specimen, declared it to represent a very distinct form not to be
confounded with any other member of the genus Empidochanes. Two years
afterwards I recorded a second example, also a female, from Itaitiiba, a small
village on the left bank of the Tapajoz River. % So far as I know, no other
specimens have been obtained since.

In 1873 Messrs. Sclater and Salvin § published the description of a new
Tyrant, Knipolegus pusillus. The type, which had been procured by A. R. Wallace
somewhere on the Lower Amazons, || remained unique till 1898, when G. K. Cherrie
was fortunate in getting two males at Perico, on the upper Orinoco, Venezuela.lf
In 1907 Miss Snethlage** shot a single male near Alcobaca, on the Tocantins, and
in the same year the late W. Hoffmanns senfe an adult male from Jamarysinho, a
village on the Rio Machados, Madeira district, to the Tring Museum.ft

Thus, it will be seen that the two known specimens of E. poecilocercus were
females, while of Knipolegus pusillus only males had been secured. When lately
investigating the affinities of Pelzeln's species I was struck: by its similarity to the
females of certain species of Knipolegus, both in structure and in style of coloration.

( 240 )

On going deeper into the question, I became convinced that it had no relation
whatever to Empidochanes^ being in every way a typical Knipolegus, and I arrived
at the final conclusion that K. pusillus and E. poecilocercus were merely male and
female of one and the same species.

Four specimens of the former and two of the latter agree perfectly with each
other in proportions, shape of the wing, development of the rictal bristles, etc.

All six examples have the three outer primaries narrowed, incised, and acumi-
nated, as described by Berlepsch and Hellmayr,* this peculiarity being equally well
pronounced in both sexes ; the nostrils are small circular openings ; there are
numerous long, rather soft rictal bristles. In coloration, the female (E. poecilo-
cercus) recalls that of K. cyanirostris (Vieill.), having the inner web of the rectrices
rufous, the upper tail-coverts cinnamon, and the chest flammulated with dusky.
The only point in which it differs from the male {K. pusillus) is the slightly
narrower bill, with more distinctly ridged (less rounded) cnlmen, and its blackish
(instead of plumbeous) colour. The same sexual difference, however, exists in the
allied species.

For the sake of convenience I append the measurements of the specimens
examined by me, together with the synonymy, range and characters of the species,
which has to stand as :

on either side, the others with the inner half of the inner web cinnamon-rnfons, and
a slight margin of the same colour along the outer web. Lores and a rim round the
eye yellowish buff; cheeks, auricular region and sides of the neck light olivaceous
brown like the back. Under surface pale primrose-yellow, throat and under tail-
coverts more buffy ; sides of throat, foreneck, and sides of body flammulated with
pale brown, most strongly on foreneck. Axillaries, under wing-coverts, and an
extremely narrow edge along the quill-lining buff. Bill blackish, basal half of

Obs. In both sexes the feathers of the pileum are somewhat elongated so as to
form a slight, rounded crest. The tail is moderately rounded, the outer rectrices
being 2 to 3 mm. shorter than the median ones. The males from the Orinoco
(Perico) are practically identical with the type in the British Museum, while that
from Jamarysinho (R. Madeira) has the upper parts duller, less bluish black. The
female from Itaituba also differs in some particulars from the type of E.poecilocercus;
the back is duller olive-brown, the auricular patch darker brown, the throat less
buffy, the under tail-coverts are more ochraceous, and the dusky stripes on the chest
darker as well as more strongly defined. These slight divergencies are most pro-
bably individual.

The type of 0. keaysi agrees very well with the Bolivian specimens except

2

(242 )

that the rump, upper tail-coverts, thigh, and flanks are rather more rnfescent
brown. The back, too, appears to be slightly more brownish green, while the edges
to the wing-coverts and remiges are deeper rufescent brown. These insignificant
variations are, no doubt, due to age, for the type of 0. keaysi is immature. The
middle of the breast and abdomen is decidedly yellowish, as in No. 2 (S. Jacinto),
whereas in the type of C. simplex the belly is nearly uniform dingy olive-green.
I agree with Count Berlepsch that this species, notwithstanding its rather divergent
bill, finds its natural place in the genus Caenotriccus. To Ockthoeca it has, as far
as I can see, no close relation.

C. simplex is only known as aii inhabitant of the mountains of Northern Bolivia
and South-Eastern Peru (Marcapata).

This bird is, no doubt, the same as T. improbus, of which the Tring Museum
has a large series from the type locality. In fact, on comparing the Santa Marta
specimen with fourteen skins from Me'rida, I cannot detect the slightest difference
either in colour or size : the back is of exactly the same shade of green ; the
darker crown forms a kind of dusky cap ; a distinct frontal band and a spot above
the brownish black anteocular patch are white, the auriculars dark olive-brown ; the
whitish superciliary line is inconspicuous, as in an adult male from Valle (January 17,
1888) ; the throat dull white ; the foreneck flammulated with pale yellowish on a
light greyish ground, etc. The pale markings on the wing show the same distribu-
tion as in Me'rida examples, but the edges to the median wing-coverts are perhaps
more whitish than in the majority of the latter.

Five adult males from Merida measure : wing 61-63 ; tail 52-55 ; bill 10-1 1 mm.

T. improbus inhabits the mountains of Western Venezuela (Me'rida) and
Northern Colombia (Santa Marta, Ocana). In the north coast ranges of Venezuela
it is replaced by T. petersi Berl. About the characters of this species cfr. Hellmayr

So far as is possible to judge from a single immature specimen, this appears
to be a distinct form, most nearly allied to 0. diadema diadema (Hartl.). It
resembles the Bogota bird in the coloration of the wings, but may be recognised

* In the original description the measurements, by misprint, are given as follows : wing 54 ;
tail 46 mm,

(243 )

by lacking the blackish cap (the feathers of the pileum being olive-green like
the back, with inconspicuous dusky central spots), by its decidedly lighter, more
greenish brown back, somewhat paler yellow frontal band, and by having the flanks
slightly washed with brownish. The absence of the dusky cap may be due to
immaturity, but the other characters, though slight, serve to distinguish 0. d.jesupi
from the young of 0. diadema. The upper wing-coverts are but obsoletely margined
with the colour of the back.

0. diadema gratiosa differs from the Santa Marta bird by its blackish cap,
much darker, rufescent olive back, more greenish breast (without yellowish
admixture), and by having the greater wing-coverts broadly tipped with cinnamon
rufous.

The three " species " replacing each other geographically are more properly
designated by trinomials.

mentioned in another connection, \\ a more detailed explanation of the case seems
desirable. My conclusions are based upon the following specimens :

The small differences noticed by Hellmayr and Seilern * as existing between
Venezuelan skins (Nos. 1 — 3) and two undoubted P. ophthalmicus (Nos. 11, 12)
are not borne out by the larger series which came to hand since our remarks were
written. It is true, the two examples from the Cauca River, including the type of
P. alleni, agree with the Cambre birds in the light cinereous pileum, clear yellowish
green back, bright sulphur-yellow colour of the anterior auricular region, and in the
lesser extent of the whitish chin-spot, as contrasted to the two specimens in the
Berlepsch Collection (Nos. 11, 12); but the series from Ecuador shows considerable
variation in all these characters, and the Bogota skin (which would be expected to
belong to the pale northern race) is fully as dark as the Huambo bird (No. 11).

In the adult male from Pichincha (No. 7) and the immature one from Coraz6n
(No. 8) the anterior auricular region is white, scarcely shaded with yellowish, as in
the Huambo specimen (No. 11), while in the two others from the same localities
(Nos. 9, 10) it is even more deeply olive-yellow than in the Cumbre and Cauca
examples. The crown is light cinereous in No. 9 (Corazon), as in the latter, but very
dark slate-grey in No. 7 (Pichincha), while the others are intermediate. As to the
colour of the back, only one of the Ecuadorian skins (No. 8, Corazon) matches
those from Venezuela, but the three others are also decidedly lighter green than

the Huambo bird. Bat again, the adult male from Mapoto and the Bogota skin
are absolutely indistinguishable from the Peruvian skin, having the head very dark
slate-grey, the back dull olive green, the anterior ear-coverts whitish, and the
breast strongly olivaceous.

From the above, it will be seen that though there is a certain individual variation,
the colour differences are not peculiar to any geographic area. Therefore, we can
admit only one form, P. ophthalmicus, ranging from Central Pern (Amable Maria,
Ropaybamba, La Gloria) through Ecuador to Western Colombia (Cauca Valley)
and North-western Venezuela (Cumbre de Valencia).

The type of Tyrannus fumigatus Lafr. & D'Orb. which has never been identified,
proves, on examination, to be an example of the species universally called Contopus
ardosiacus (Lafr.). There are four specimens from the same country in the
Berlepsch Museum, while the French National Collection possesses an nnsexed
adult bird obtained at Tilotilo, Bolivia, by the late Clarence Buckley. On com-
paring the six Bolivian skins with a considerable series from North Peru (Tambillo),
Western Ecuador, Colombia (Bogota) and Western Venezuela (Andes of Merida),
I find several well-marked differences which warrant the recognition of a darker,
northern form, Myiochanes fumigatus ardosiacus (Lafr.). The Bolivian birds are
altogether paler and lighter in coloration : the back is clear sooty grey with an
olivaceous tinge, the sooty blackish crown forming a rather well-defined dusky cap ;
the under parts are lighter olivaceous grey, with the throat and middle of the belly
decidedly whitish. These characters are strongly pronounced in the fresh plumage
(Nos. 1 — 5) ; the Tilotilo bird (No. 6) — in very worn, abraded condition— is scarcely
lighter above than Bogota skins in corresponding stage, but the much paler

(246 )

uuder-surface serves to distinguish it at a glance. In the northern race * the back
is much darker sooty grey, being little, if anything, lighter than the crown ; the
whole under surface, from the chin to the anal region, is uniform sooty grey
[very nearly as dark as the upper parts], the under tail-coverts only being edged
with whitish.

Count Berlepsch f has united Contopus brachyrhynchus Cab., \ from N.W.
Argentine, with M. f. fumigatus, as defined above. In fact, when studying the
type, forwarded by the authorities of the Berlin Museum, in company with the
Count several years ago, I could not perceive any material difference between
the Bolivian series and the Tucuman bird. However, it should be noted that the
type specimen of C. brachyrhynchus, in bleached breeding plumage, is not quite fit
for the purpose of comparison. Since that time I have had the opportunity of
examining five adults from the mountains of N.W. Argentine, § and they appear to
me to represent another recognisable form, characterised by its very pale colora-
tion. The nape, back and sides of the head, instead of being sooty grey, are light
smoke-grey tinged with olivaceous, the crown nearly concolour with the mantle ;
the throat is more whitish ; the breast much paler greyish, and the yellowish white
area in the middle of the belly far more extended. The wings are apparently
somewhat longer (98 — 101 mm.).

There are, thus, three races to be distinguished :

(a) Myiochanes fumigatus ardosiacus (Lafr.) || the darkest, ranging from
Central Peru through Western Ecuador to Colombia, Western Venezuela (Merida)
and British Guiana (Roraima).

(b) Myiochanes fumigatus fumigatus (Lafr. & D'Orb.), lighter, with whitish
admixture on throat and middle of belly, inhabiting the highlands of Bolivia.

(c) Myiochanes fumigatus brachyrhynchus (Cab.), the palest, occurring in the
high mountains of North-Western Argentine (Tucuman, Jujuy). 1[

The recently described Myiochanes ardosiacus polioptilus Todd, ** from the
Venezuelan coast-mountains — which I have not seen — appears to be a fourth
member of this group, and should be called M. fumigatus polioptilus Todd.

and the cheeks, ear-coverts and sides of neck dingy olive-grey (instead of deep
buff). Furthermore, the interscapular region is darker, dull rufescent brown, with
a greyish tinge (instead of bright tawny brown).

I am unable to discover any other constant differences. Though the type
has rather light ochreous under parts, passing into buffy whitish (not " greyish
white," as said in the original description) on the throat, the Cayenne bird does
not differ in this respect from Upper Amazonian examples.

The two races are, however, closely allied, and represent each other geo-
graphically, so that their natural relationship seems more correctly expressed by
trinomials. I herewith give the synonymy, together with a short re'sumS of their
range and characters.

The two specimens from Santa Marta (Nos. 3 and 4) are practically identical
with the type in the Paris Museum. The latter has the ochreous frontal band and
the sides of the face slightly paler — differences no doubt due to fading, for it has
been exposed to the light in the galleries for many years. The Ejido bird, a fresh
skin in good condition, agrees in every particular with the Colombian specimens.
C. browni becomes, therefore, a synonym of G. ferrugineipectus.

This scarce species inhabits the mountains of North-western Venezuela (Silla
de Caraccas, Ejido) and Northern Colombia (Sierra de Santa Marta), occurring
exclusively at high elevations.*

Agyrtria alleni, a species not identified by Salvin and Hartert, proves to have
been based upon a female of C. oenone josephinae, a well-known Bolivian Humming-
bird. The type specimen is practically identical with a female from Songo, western
Yungas, in the Berlepsch Collection.* They agree in the dull bluish green tint of
the forehead and crown, and in the reddish bronze tail, the three outer pairs of
rectrices having, in both specimens, a distinct, pale greyish apical spot. Like the
Songo example, the type has the throat and malar region spotted with glittering
golden-green on a white ground, these spots being absent on the chin and but barely
indicated along the median portion of the upper throat ; the foreneck is white, with
bronze-green (not glittering) apical edges ; the remainder of the under parts dull
white, washed with metallic green on the flanks ; under tail-coverts pale greyish,
edged with whitish, upper tail-coverts fiery reddish bronze, much the same as in
the Songo bird. The bill, in Nos. 1 — 5, is quite alike both in shape and colour, the
maxilla being black, the mandible pale brownish with dusky tip.

Count Berlepsch,, who has seen the type, entirely concurs with my identification.
Agyrtria, alleni is consequently to be placed among the synonyms of C. o.josephinae,
whose range appears to be restricted to the forests of Bolivia.

65. On the group of Saucerottia sophiae (Bourc. & Muls.).

The latest reviewer, Mr. Ridgway,t distinguished four races of this group,
calling them : Saucerottia sophiae sophiae (Costa Rica and Nicaragua), S. sophiae
saucerottei (Western Colombia), S. sophiae warscewiczi (Northern Colombia), and
S. sophiae braccata (Andes of Venezuela). The specific names are applied in the
same sense as by Dr. Hartert, J who, however, separated S. sophiae, S. saucerottei
and S. warscewiczi specifically, regarding S. braccata as a subspecies of the last-
named form. To my mind the arrangement put forward by Ridgway is the most
correct expression of the natural affinities of these birds, which agree in structure as
well as in general style of coloration, and present only slight (though perfectly con-
stant) differences in the colour of the upper and under tail-coverts.

Trochilus Sophiae Bourcier et Mnlsant, § though originally based upon
Bogota skins, has generally been referred to the Costa Rica form with coppery or
purplish bronze rump and mainly steel-blue under tail-coverts. This misapplication
of the name is evidently due to the fact that the alleged type, in the Elliot collec-
tion (now the property of the American Museum of Natural History), marked
"Nicaragua" || belongs to the Central American race. However, on consulting

( 250 )

the original description it is easily seen that this example cannot be the true type
of T. sophiae. Bourcier and Mulsant characterise their species as follows : " Dessus
du corps rev£tu de plumes soyeuses, d'un vert moins fonc6 et plus luisant sur la
nnqne, les convertures alaires et la moiti6 anterieure du dos, passant au vert cuivreux
sur le croupion et la couverture caudale, dont les dernieres plumes sont d'un bleu
d'acier . . . Couverture sous-caudale, forme'e de plumes d'un vert bronze, ou d'un
gris bronze, e'troitement borde' de blanc." This entirely disagrees with the Costa
Rica form, in which the uropygium and upper tail-coverts are strongly glossed with
coppery or purplish, while the lower tail-coverts are decidedly steel-blue with greyish
edges. On the other hand, the above terms apply perfectly well to S. saucerottei,
of Western Colombia, which is also found in Bogota collections.* This species
(of which the Munich Museum possesses a couple from Cali, the type locality) has
the rump and upper tail-coverts bronzy green, the longest feathers only dull steel
bluish with coppery margins, and the under tail-coverts dusky brown, edged with
whitish.

Moreover, there is in the Paris Museum a nearly adult specimen f from
Colombia (id est Bogota), named and presented by Bourcier himself, which
corresponds exactly to the description of T. sophiae and, besides, agrees in every
respect with typical S. saucerottei from Cali ! Hence, there seems little doubt that
T. sophiae is the same as S. saucerottei^ while the bird found in Costa Rica and
Nicaragua ought to be called S. ho/manni (Cab. & Heine). } Those who might
object that so excellent an expert as Bourcier would not have described the same
species under two different names I would remind of the case of Lafresnaya saiil
(Del. & Bourc.). This species was first made known by Delattre and Bourcier §
under the name Trochilus saiil, but in another paper published nearly simultane-
ously it was redescribed as T. gayi by Bourcier and Mulsant ! ||

Mr. Ridgway (I.e.) accepts S. sophiae as the oldest specific title for the group.
It appears, however, that the article in the Revue Zoologique containing the account
of Trochilus saucerottei Del. & Bourc.,1[ has a slight priority, as may be inferred from
a note in the same periodical (on page 314) concerning the memoir in the Annales
des Sciences phys. et nat. etc. de Lyon**

Therefore, the nomenclature of the various forms has to stand as follows :

N.B. Trockilus caligatus Gould * is certainly not the Central American form,
but may be an earlier name for S. s. warscewiczi. The description fits the Santa
Marta bird exceedingly well. Cfr. " upper tail-coverts and tail bright steel-blue,
under tail-coverts the same, fringed with white." The type (if still extant) should
be re-examined.

Mr. Ridgway f states : " I have not seen this species, which seems to be very
distinct." In company with Mons. Simon, I have carefully compared the type with
a good series of the West Peruvian A. amazilia^ and have not the slightest hesita-
tion in saying that it is merely a specimen of that species with wrong locality. It
agrees in all essential points with examples from the West Coast of Peru in the
Paris Museum and in Mons. Simon's collection, and differs only by its slightly more
coppery green upper parts and by having the tips to the median rectrices a shade
darker, more blackish green. One example from Peru, however, approaches it very
closely. The maxilla is wholly black, as in a Lima specimen in Coll. Simon ; the
coloration of the under parts is exactly the same as in A. amazilia — the throat and
foreneck being golden green, the middle of the breast and abdomen white, the
flanks pale rufous, etc. Contrary to Dr. Hartert's statement, t the type does not
differ in size from ordinary Peruvian specimens.

It is well to remember that the type was bought by the late Adolphe Boucard
in San Francisco from a dealer who told him it had been obtained by Forrer at
Mazatlan. But the " make " of the specimen is very different from that of
authentic Forrerian skins, and as no collector has ever met with the species about
Mazatlan, we may fairly assume that the assigned locality was an error. A. forreri
is, therefore, to be excluded from the Mexican Ornis and enters into the synonymy
of Amizilis amazilia (Less.).

67. Amizilis ellioti (Berl.) replaces A. verticalis auct.

Both Dr. Hartert * and Mr. Ridgway t applied the name Trochilus verticalis
Lichtenstein J to a species with (immaculate) white under tail-coverts found
in the western and central states of Mexico (Sonora, Sinaloa, Jalisco,
Michoacan, etc.). In Eastern Mexico (states of Vera Cruz, Oaxaca, and Chiapas)
occurs the nearly allied A. cyanocephala cyanocephala (Less.), chiefly characterised
by having the under tail-coverts olive-grey, faintly glossed with bronze and
margined with white.

Trochilus verticalis was founded upon specimens obtained by the Prussian
travellers Deppe and Schiede in the late twenties of last century. Thanks to the
courtesy of Drs. Reichenow and Lorenz, I have been enabled to examine three
examples, belonging to the Berlin and Vienna Museums respectively, all marked
by Lichtenstein himself as " Trochilus verticalis" They were collected by Deppe
at Perote, a place situated between Puebla and Jalapa, in the state of Vera Cruz,
Eastern Mexico. These skins are unquestionably identical with the bird known as
A. cyanocephala, having the sides of the neck metallic green, and the under
tail-coverts pale brownish olive, edged with white, and agree in every respect with
a series from Jalapa and Oaxaca.

T. verticalis is, therefore, to be relegated to the synonymy of Amizilis
c. cyanocephala, while the West Mexican species has to bear the name Amizilis
ellioti (Berlepsch).

C. euleri is certainly the rarest among South American Cuckoos. The type
was obtained by Euler at Cantagallo, in the province of Rio de Janeiro, and is
preserved in the Berlin Museum. Mr. Stone recorded a specimen from the interior
of British Guiana that had been forwarded to the Academy of Natural Sciences of
Philadelphia. In the British Museum there is a second example from the same
country, taken by H. Whitely at Aunai on June 24, 1889. H. H. Smith secured a
single male near Chapada, Mattogrosso, S.W. Brazil, on October 28, 1883, which is

in the American Museum of Natural History in New York. This is the specimen
referred to by Allen and Chapman. According to the latter author, the type of
C. Undent, collected by Linden at Santarem, on the mouth of the Tapaj6z, and
forming part of the Museum of Comparative Zoology at Cambridge (Mass.),
belongs also to the same species.* To these are now to be added the two
examples given at the head of this article, making a total of seven records.

The specimen of Natterer's (who, as in so many other cases, was the real
discoverer of the species) answers well to the original description. C. euleri is, in
fact, only a diminutive form of the North American G. americanus (Linn.), but has
no rufous whatever on the wings, and nearly pure white (instead of buff) axillaries
and under wing-coverts. The colour of the bill is exactly the same : maxilla
black, basal half of maxillary tomium and the mandible orange-yellow, extreme tip
of the latter blackish. The upper parts are pale greyish brown, glossed with bronze
(like C. americanus) ; the anterior portion of the pileum, lores, and an obsolete
stripe above the eye cinereous; auricular region pale brown, darkening anteriorly ;
wing-coverts pale bronze-brown, like the back; remiges dusky, outer webs light
brown, with bronzy sheen ; three outer pairs of rectrices black, with long white
tips, the two succeeding ones light bronze-brown, passing into blackish terminally
and ending in a narrow white margin, the median pair wholly bronze-brown ;
under surface white, foreneck and sides of breast faintly washed with greyish ;
inner web of quills broadly edged with pale buff at basal portion.

The Surinam bird is rather larger, with longer bill, and the buff quill-lining
is less conspicuous. These trifling variations are most probably individual.

C. euleri, notwithstanding its rarity in collections, appears to be rather widely
distributed in South America, ranging from the Guianas to Southern Brazil (Sao
Paulo). Nothing is known about its life-history, but it is doubtless a resident and
not a migrant from some northern country.

Cuculus velox was described by Dr. Andreas Wagner, then Curator of the
Zoological Collections at Munich, from an example obtained by Karwinski some-
where near the city of Mexico (exact locality not stated). Shelley f put it down as a
synonym of G."mexica,nus" — G. calif ornianus (Less.), but examination of the type
specimen proves this view to be erroneous. The type, an adult bird in rather worn

* Dr. Allen says that the " strongly cinereous colour of the lower parts " is a conspicuous feature
in C. lindeni. This does not well agree with the specimens examined by me, in which the under surface
is nearly pure white.

(254)

plumage, agrees in all essential particulars with G. affinis, of which Count
Berlepsch most obligingly sent me a skin collected by Rockstroh in Guatemala.
The under parts are uniform buff, paling into whitish on chin and upper throat ;
the lower tail-coverts blackish brown with lighter brown tips (not bull as in
G. californianus) ; the sides of the foreneck and chest only are marked with broad,
black shaft-stripes. Above, the crown and nape are black, with white apical spots ;
the back, instead of being pale bronze greenish, as in G. calif or nianus, is bright
rufescent-brown ; also the upper wing-coverts and inner secondaries (tertials) are
metallic brown with coppery reflections, not greenish bronze.

The naked space behind the eye, supposed to be lacking in the type specimen,
is developed to the same degree as in other examples, but the taxidermist (who
probably took it for a deficiency) had very cleverly covered it with small feathers —
which, however, can be easily removed.

There is, of course, the possibility that larger series may show the Guatemalan
birds to be subspecifically separable from the typical Mexican form. The point
I wish to emphasize is that Cuculus velox belongs to the gror.D of Geococcyx
affiniS) and has no relation whatever to G. californianus (Less.).

70. Ramphastos citreopygns Gould is an artefact !

Ramphastos citreopygus Gould, Monogr. Ramph. (1st ed.) pi. iv (1834.—" believed . . . from Peru " ;

Cantabrigiae — Swainson Collection, Type of R. citreopygus Gould, Monogr. ed. 1."
Wing 215 ; tail 136 ; bill 156 mm.

R. citreopygus has been completely lost sight of ever since it was described
by Gould in 1834, being not even mentioned either in the second edition of
Gould's Monograph or in the Catalogue of Birds. The type specimen, kindly
forwarded to me for inspection by Dr. Gadow, turns out to be an artefact : the body
is taken from R. mtellinus Licht., to which is very cleverly attached the head of
R. monilis P. L. S. Mull. (= erythrorhynchus Gm.). It is only fair to state that
Dr. Gadow had already arrived at the same conclusion.

The bill of the substituted head-portion agrees in colour and shape with
R. vitellinus, of which a large series from the Guianas and Trinidad has been
examined, while the body does not present any difference from the well-known
R. monilis.

Consequently R. citreopygus is to be eliminated from the list of existing
species.

71. Aulacorhynchus * wagleri (Sturm) — a nomenclatorial Note.

In 1835 J. Gould described and figured a Mexican species of Toucan from
a single example in the Munich Museum under the name Pteroglossus pavoninus. f
The same specimen was made the type of a new species, Pteroglossus wagleri \
by Sturm, six years afterwards. The purpose of this note is to show that the
correct specific name of the species in question is that given by Sturm.

* This term was generally supplanted by the later Aulacorliamplms Gray on the insufficient
ground of having been previously employed in botany.
t Monogr. Ramph., Part iii, 1835.
% Monogr. Rhamphastiden, 2. Heft, 1841, tab. [6],

( 255 )

The first author to use the adjective pavoninus in combination with
Pteroglossus was apparently Wagler ; * but his excellent description — taken from
a single bird from Valle Real, Mexico, in the Berlin Museum — leaves no doubt
as to its being referable to Aulacorhynchus prasinus auct. In fact, Gould, four
years later, founded his Pteroglossus prasinus (Lichtenstein MS.) f on the very
same specimen in the Berlin Collection !

However, in spite of its undoubted priority, pavoninus (1829) cannot replace
prasinus (1833), for Wagler evidently had no intention of creating a new name
of his own, but merely employed Gmelin's old term, t

Ramphastos pavoninus Gmelin § is described as " R. viridis, pennis rubris et
pavoninis hinc inde inter spersis," and refers, no doubt, to some artefact.
Consequently, this name should be altogether disregarded. The nomenclature
of the two green Mexican Toucans stands, therefore, as follows :

(a) Aulacorhynchus prasinus prasinus (Gould).

Aulacorhamphus pavoninus (errore) Salvin & Godman, Ibis, 1889, p. 240 (Amula, Sierra Madre
del Sul, Guerrero, Western Mexico).

This western form differs from A. p. prasinus in its dull yellowish frontal
band and oily-green crown ; by lacking the narrow, pale bluish green superciliary
streak ; and by having the black patch at the base of the culmen confluent with
the black stripe along the maxillary tomium. Besides the type, the Zoological
Museum at Munich possesses a second adnlt specimen, both without any further
indication than " Mexico." The wing measures 128-129, the tail 125-127, the
bill 75 — 77£ mm.

A. p. wagleri appears to be very rare in collections. The late A. Boucard
obtained an example at Xacatepec in Oaxaca, Mrs. H. H. Smith another in the
Sierra Madre del Sal, state of Guerrero. Additional specimens doubtless exist
in American museums.
