C. Our knowledge of the ectoparasite fauna of the Philippines is very scanty. Even such medically important insects as the fleas are poorly known, particularly from the higher eleva- tions. Thompson (1), in 1938, listed only two species as having been recorded from the Philippines. The collection made by the Chicago Natural History Museum Expedition would therefore be appreciated for these reasons alone. Fur- thermore, a total of two new genera and five new species are represented, and the new forms present highly interesting adaptations, modifications and affinities. The two new genera are being described elsewhere (3, 4), and herein are described three new species. Once more I am indebted to Mr. Harry Hoogstraal, leader of the Expedition, and to the Chicago Natural History Museum, for some splendid contributions to the study of Siphonaptera. Family Pygiopsyllidae Subfamily Pygiopsyllinae Stivalius pomerantzi sp. nov. (Figs. 1, 3, 5-10) Diagnosis.—Distinet from known Stivalius in that the apex of exo- podite is not produced caudad apically. Near Stivalius robinsoni (Roths- child 1905), but readily separated by the following characters: Anterior dorsal angle of metepisternum acute, not rounded. Eye somewhat reduced. Special spinose process below male ninth sternum absent. Distal arm of ninth sternum lacking spiniforms at midpoint of caudal margin. Sclerite below insertion of exopodite with long axis parallel to that of exopodite, not at right angles. Apical sclerite of median dorsal lobe of aedeagus apically truncate (fig. 3), not acute (fig. 4). Armature of inner tube of aedeagus reduced; not represented by a *Published under the auspices of the Surgeon General, Department of the Army, who does not necessarily assume responsibility for the professional opinions ex- pressed by the author. 1—Proc.

Trough of aedeagal endchamber extending only to near apodemal strut, not to cephalic third of aedeagus. Description Head (fig. 1).—Frontoclypeal margin evenly rounded. Pores of microsetae scattered anterior and dorsal to first row of bristles, but those between the first and third rows with larger setae. First pre- antennal row with six or seven bristles, excluding two at insertion of maxillary palpi. Second row of four bristles, the most dorsal and most ventral the longest. Third row of four, the uppermost by far the longest. Fourth row consisting of a small bristle near eye and two long bristles near insertion of maxillary lobe. Eye somewhat reduced by virtue of a large ventral sinus extending about one-third its diameter, otherwise large; located near posteroventral corner of preantennal region of head. Genal process acuminate, enclosing a triangular un- pigmented area near ventral margin of head. Maxillary lobe (MX.) ~ extending to near apex of maxillary palpi. Labial palpi (Z.P.) five- segmented, extending to apex of forecoxae. Bristles of second antennal segment very short except for one or two ventral ones which reach to midpoint of club. About 20 or 22 very small bristles along dorsal and posterior margin of antennal fossa. Postantennal region with three rows of bristles arranged 3(4)-5-6 with a large intercalary bristle near antennal fossa, between basal bristles of second and third rows. Thorax.—Pronotum with three rows of bristles, the first row very incomplete. Pronotal comb with ten spines on a side. Mesonotum with five rows of bristles, the first two rows very small, somewhat irregular; bristles of the last two rows the longest, those of ultimate row twice as long as penultimate. Mesepisternum (MPS.) with four bristles all near or in ventrocaudal corner. Mesepimere (MPM.) with seven bristles arranged as in figure. Metanotum with four rows of bristles, the first row incomplete. Lateral metanotal area (fig. 7, Z.M.) distinct, with dorsal ridge (R.) well sclerotized but with ventral ridge (V.R.) feeble; with a bristle where dorsal margin meets caudal margin. Pleural arch (PL.A.) at junction of metanotal ridge and pleural ridge, strongly convex, well-developed. Metepisternum (MT7S.) with one bristle near dorsocaudal angle; anterodorsal angle acute and upturned; with an accessory link or vinculum (VC.3A.) near anterodorsal angle.

Legs.—Metacoxa with mesal thin short bristles near anteroventral angle, and with two lateral bristles at insertion of trochanter. Profemur with about 12 thin, short lateral nonmarginal bristles; on each side a row of widely separated ventromarginal bristles, the proximal one fairly long, the others short except for subapical one and apical one. Mesofemur with a similar row of ventromarginal bristles but with apical three long. Metafemur as mesofemur in this regard. Metatibia (fig. 6) with but one unpaired dorsolateral large bristle and five pairs of such bristles; with three apical bristles below the last pair, that near dor- solateral margin the longest, the middle one next longest. Metatibia with about 27 small lateral bristles, excluding strictly marginal ones. [4] PLATE II PROC. BIOL. SOC. Ki STIVALIUS POMERANTZI N. SP.

Sterna three to six with four or five rows of bristles, the first two rows short. Upper antepygidial bristle (fig. 5, A.B.) slightly more than one-half length of ventral one. Modified Abdominal Segments (fig. 5).—Eighth tergum reduced to a small indistinct area between antepygidial bristles and sensilium; with small thin bristles. Eighth sternum (8S. and fig. 10) very large, extend- ing as far dorsad as near apex of exopodite, much more caudad than distal arm of ninth sternum, as far cephalad as apex of proximal arm of ninth sternum; with about 67 bristles arranged as in figure. Immovable process of clasper (P. and fig. 8) reduced, not produced into a finger-like process; dorsocaudal margin sinuate, deeply concave at insertion of exopodite; with one long, one very short apical bristle; the largest apical bristle distal and ventral to ventroproximal angle of exopodite.

Exopodite with scattered short thin marginal bristles, especially apically and subapically. Exopodite with five long bristles well apicad of midpoint of ventrocaudal margin; the most proximal of these bristles the smallest; the bases of the bristles equidistant from each other; the most apical bristle inserted proximad of apex for a distance equal to about one-sixth of its length. At base of exopodite a conspicuous sclerite twice as long as broad; about as long as base of exopodite is broad; with margins concave. Manubrium (MB.) broad, almost half as broad as long, even broad near apex. Ninth tergum greatly reduced to an indefinite area between its apodeme and clasper lobe. Ninth sternum roughly boomerang-shaped. Proximal arm of ninth sternum (P.A.9) truncate apically. Distal arm of ninth sternum (D.A.9 and fig. 9) broad; apical half of ventral margin strongly convex; talon-like apically; dorsal margin biconcave, the lobe between the con- PLATE ITI PROC. BIOL. SOC.

[6] Traub—Fleas Collected in the Philippines 7 cavities also with a sinus; with three subapical short stout bristles, al- most suggesting spiniforms, on ventral margin; with about 20 long or longish ventromarginal bristles extending proximad nearly to midpoint; no bristles on dorsal margin, except for one subapical small one. Aedeagal apodeme (fig. 3, A#.A.) slightly longer than aedeagus proper. Trough of endchamber extending slightly cephalad of apodemal strut. Wall of aedeagal pouch (P.W.) ventrally fairly well sclerotized. Median dorsal lobe (M.D.L.) bifid apically, each branch truncate, the upper one subvertical. Within each side of median dorsal lobe, a large apical sclerite (A.M.S.) which consists of a more heavily sclerotized mesal portion and a larger, more dorsal, lateral, less sclerotized section. Ventral portion of endchamber obscured by distal arm of ninth sternum in specimens extant. A sickle-shaped sclerite (CR.) denoting ventro- apical portion of crochets. Sclerotized inner tube (S.I.T.) straight, relatively unarmed, ventral in position. Apodemal strut supporting inner tube of usual type, but lobes not sharply differentiated. Crescent sclerite (C.S.) well developed. Penis rods (P.R.) uncoiled, short, not reaching to cephalic end of aedeagal apodeme; united for virtually all their length. Aedeagal apodemal rod (A.A.R.) present, arising from base of aedeagus. Vesicle (V.) at apex of A.A.R. fairly well-developed. Tenth abdominal segment conspicuous by virtue of the large convex sensilium (fig. 5, SN.), which is almost as high as long. Dorsal lobe of proctiger with a subapical row of bristles and very small dorsomar- ginal ones. Ventral lobe of proctiger with ventromarginal bristles at apical half; the apical bristles very long. Types.—Holotype ex Rattus sp., collected by Harry Hoogstraal, 20 August 1946. Philippine Islands: Mindanao, Davao Province, Hast Slope of Mt. McKinley, elev. 3300 ft. Deposited in Chicago Natural History Museum. Paratype male with same data in author’s collection. Female unknown. Kemarks.—This species is named for Mr. Charles Pomerantz, who by his studies on mites and rickettsialpox contributed so much to the science of Parasitology. Stivalius ralius sp. nov. (Figs. 11-16) Diagnosis.—Agrees with S. pomerantzi in that the anterior dorsal angle of the metepisternum is acute and upturned, and the eye is some- what reduced. Distinct in that there are two almost contiguous mar- ginal sensory pits on clypeus, not one; the preantennal region bears 14 longish bristles, not 16; the mesepisternum three bristles, not four; the mesepisternum five, not seven, the metepisternum 11 longish bristles, not 13 or 14; the metatibiae bear two stout unpaired dorsomarginal bristles following the first paired set, not merely one; metatibia with only about 20 small lateral bristles; the labial palpi extend beyond apex of forecoxae instead of to near apex. Readily separated from 8S. robinsoni (Rothschild 1905) by the absence of a distinct sinus on the seventh sternum, by the fact that the tail of the spermatheca (fig. 15) does not distinctly enter the head and by the absence of the deep median dorsal sinus on the spermatheca (fig. 2, S. robinson). PLATE IV PROC. BIOL. SOC. WASH., VOL. 64 STIVALIUS RALIUS N. SP. [8] Traub—Fleas Collected in the Philippines 9 Description. Head, Thoraz.—(Only salient differences from S. pomerantzi are included here. Distinctions believed to be secondary sexual character- istics, such as shape of head and length of antennae, are excluded.) Preantennal region with bristles arranged roughly 4-3-4-2-1, the median bristle at eye level the longest (fig. 12). Unpigmented portion of eye extending to about midpoint of eye. Postantennal bristles 5-6-7, and, in addition, a large intercalary bristle near midpoint of antennal fossa. Labial palpi extending to about middle of trochanter. Bristles of mesepi- sternum (fig. 13, MPS.) arranged 1-2; those of mesepimere (MPWM.) arranged 3-2. Metepisternum (MT7S.) with apparently two bristles, at least one very small. Metepimere (M7TM.) with six bristles anterior to and/or slightly ventral to spiracle, and two longer ones caudad of spiracle; three additional bristles on ventral half. Legs.—Femora lacking a complete row of ventromarginal bristles, but with two proximal ventromarginal bristles on pro- and mesofemora, and three on metafemora. (In Stivalius, the females frequently have fewer such bristles than the males.) Dorsolateral bristles of metatibiae arranged 1-2-1-1-2-2-2-1-3.

This species characteristically parasitizes squirrels throughout much of the Malayan Archipelago, particularly at the lower elevations. The aedeagus (fig. 4) has not been described heretofore. Trough of aedeagal endchamber very long, extending as far cephalad as proximal third or fourth of aedeagus, where the wall of the aedeagal pouch (P.W.) curves to meet it. Lateral plates (Z.PT.) feebly sclero- tized ventrally, especially in central section. Median dorsal lobe (M.D.L.) strongly convex near apex, there becoming cleft and curving ventrad to meet apex of the subovate short lateral lobes (Z.L.); en- closing the characteristic apico-median sclerites (4.M.S.) which are beak-shaped distally. Between the bases of the apico-median sclerites is a thumb-like sclerite extending dorsad (D.T.). Associated with both of these structures is a ventrad-directed acuminate sclerite opposing the beak or claw of A.M.S. Sclerotized inner tube (S.I.T.) fairly straight and simple except for a dorsal spur and a pair of heavy flank- ing sclerites (A.I.T.) which are ventrally broad and straight, dorsally somewhat bluntly pointed. Crochets (CR.) apparently boomerang- shaped, arising from near A.M.S., ventral arm subcylindrical, paralleling sclerotized inner tube. With a subdorsal thin sclerotized rod extending cephalad from near base of A.M.S. and apex of A.I.T. to a point well past the apodemal strut. Crescent sclerite (C.S.) well-developed. Apo- demal strut somewhat of usual type, but with ventral lobe extending below level of the penis rods. With a well-developed vesicle (V.) at apex of aedeagal apodemal rod (A.A.R.). Penis rods (P.R.) short, thick, uncoiled, united for virtually all their length.

F. Werner, 8 January 1947 (R.T. #6520). Stivalius spiramus Jordan 1926 Advantage is taken of this paper on Philippine records to include a note from Dr. Karl Jordan (in litt). He states that his Stivalius spira- mus (1926) is at most a subspecies of Stivalius cognatus J. & R. 1923; he was misled by the badly preserved females available at time of description. Family Ceratophyllidae Subfamily Ceratophyllinae Dasypsyllus gallinulae (Dale, 1878) This species was supposed to be holarctic, but I have a series from Panama, which, altho showing some slight differences, is still regarded as representing the typical form (verified by Dr. Karl Jordan). The occurrence of this species in the Philippines is even more surprising. The genus occurs in the Malayan Archipelago, D. klossi Rothschild 1919 (female only) having been described from Sumatra. The morphological differences of the Philippines specimen probably do not validate the erection of a subspecies. Harry Hoogstraal and Floyd Werner collected one male of this species from Turdus poliocephalus kelleri, a thrush, from Davao Province, Mindanao: East Slope of Mt. McKinley, elev. 7800 ft., 1 November 1946 (R.T. #6529). This bird was also host to a new genus described elsewhere (4). Family Ischnopsyllidae Subfamily Thaumapsyllinae The remarkable genus Thaumapsylla Rothschild 1907 has been re- cently placed in a separate subfamily by Jordan (2). At that time, two species had been described, one African (7. dina Jordan 1937), and one African and Indo-Malayan (7. breviceps Rothschild 1907). A few species has been noted in the Chicago Natural History Museum material from the Philippines. Correspondence disclosed that this new species has been known for some time by Dr. Karl Jordan of the PLATE VII THAUMAPSYLLA BREVICEPS ROTHSCHILD 1907 [14] Traub—Fleas Collected in the Philippines 1d British Museum at Tring and by Mr. G. H. E. Hopkins, who is now also working at Tring. At their suggestion, this species is described by me at this time. I wish to thank Dr. Jordan and Mr. Hopkins for their generosity and for furnishing additional records. Thaumapsylla longiforceps sp. nov. Diagnosis——Close to Thaumapsylla breviceps Rothschild 1907 but readily separated by the following characters. Immovable process of elasper (fig. 17, P.) much longer, being nearly thrice as long (measured from dorsocaudal angle of manubrium) as the fifth metatarsal segment; its dorsal margin with a shallow sinus; the caudal margin rounded. In T. breviceps, P. (fig. 30) is only about twice the length of the fifth metatarsal segment; its dorsal margin is convex; its caudal margin above the acetabular bristles is virtually straight. In the new species, the exopodite F. (fig. 17) extends above the dorsal margin of P.; in T. breviceps the apex of F. is below the dorsal margin of P. In T. longiforceps, the aedeagal erochets (fig. 20, CR.) are cleaver-shaped with the handle pointing distad and somewhat subglobular apically; there is a sclerotized fold (A.M.S.) near the apex of the dorsal lobes of the aedeagus (M.D.L.), but no heavy sclerite at the apex of the sclerotized inner tube. In TZ. breviceps the aedeagal crochets (fig. 26, CR.) are of a very different shape, being smaller, narrowing only gradually, apically subacuminate and curved ventrad or caudad; 4.M.S. is inapparent, but there is a well-developed sclerite (A.S.T.) by the apex of the sclerotized inner tube. In the new species the basal abdominal sternum of the female bears two bristles, rarely one; the seventh sternum (fig. 21, 7S.) bears about five to eight long bristles (usually five or six, rarely eight) and has a very large sinus; the lobe above the sinus somewhat acuminate. In Tf. breviceps the basal sternum is nude, while the seventh sternum (fig. 29, 7S.) bears about eight to eleven bristles (usually eight or nine) and has a very small sinus, the dorsal lobe of which is rounded. In T. longiforceps, the posterior row of postantennal bristles consists of an uninterrupted row of about 11 or 12 bristles, whereas in 7. breviceps this row typically consists of about eight or nine bristles, a gap occurring between about the sixth and eighth bristles near/on the dorsal heavily sclerotized area. Other differences in chaetotaxy, altho somewhat variable, are pointed out in the description of T. breviceps _ which follows that of the new species. Description. Head (fig. 18, male).—Frontoclypeal margin evenly rounded. With a submarginal row of five short thin bristles; between each of these bristles an irregular row of three to six tiny setae. With one very long bristle inserted along middle of anterior antennal ridge. Cephalic comb consisting of two subtruncate stout spines. Genal process broad, somewhat rounded. Eye reduced to a mere vestige in lower genal angle. Maxillary lobe extending to about third segment of maxillary palpi.

With about three to five short stout bristles bordering dorsal ridge 16 Proceedings of the Biological Society of Washington above antenna; postoccipital region with three rows of bristles: the first row consisting of two or three short stout bristles, the ventral (or middle) one much the longer; the second row of three or four short stout bristles (in male, an additional clump of three to six tiny hairs beneath and between the ventral two large ones); the third row of about ten to twelve stout bristles, the lowest two or three at antennal groove shorter than the rest, the uppermost three or four inserted on a densely sclerotized area. Thorax.—FPronotum very short, with a row of six bristles; densely sclerotized beneath the uppermost two of these; the row of bristles set off from the comb is bordered by a vertical suture with non-sclerotized margins; with two very small intercalary bristles between the larger ones. Pronotal comb remarkable for its length, extending well onto prosternum; consisting of about 17 spines on a side. Mesonotum (fig. 22, MSN.) with a posterior row of five long stout bristles, with two to four tiny hairs intercalated between the bases of all but the upper two of this row; with about 23 additional shorter thicker bristles irregularly arranged in three or four rows and, in addition, anterior to these 10-15 much shorter submarginal bristles or hairs. Mesonotal flange usually with two mesal pseudobristles, probably presenting ves- tigial spiniforms. Mesepisternum (MPS.) variable, frequently with six bristles arranged 3-2-1. Mesepimere (MPM.) with about six to eight bristles, including those on the sclerotized band between the two sclerites. Metanotum (MTM.) with two rows of bristles, those of posterior row about twice the length of those of first row; with three apical spinelets on each side. Lateral metanotal area (Z.M.) not set off as a distinct sclerite, its dorsal ridge not sclerotized; with two bristles. Lacking a definite pleural arch at junction of metanotal ridge and pleural ridge. Metepisternum (MTS.) with three bristles near posterior margin.

Usually only the anterior abdominal terga have the first row of bristles developed; the second row of bristles extending ventrad of spiracle. Middle antepygidial bristle well-developed, others minute, altho ventral one slightly longer than upper. Modified Abdominal Segments. Male.—Wighth tergum with two or three long bristles posterior to spiracle (fig. 17, 87.). Eighth sternum large, about twice as broad as long; caudal margin straight; with four submarginal large bristles. Immovable process of clasper (fig. 17, P.) very long, about two and one-half times as long as broad (measured from origin of manubrium), dorsal margin sinuate, the shallow sinus at apical two-thirds; with four or five thin marginal bristles as dorsal margin curves ventrad; caudal margin convex; ventral margin concave at junction with manubrium but soon becoming convex, then fairly straight to insertion of two stout acetabular bristles at junction with caudal margin. Exopodite (F.), or movable finger, longer than broad and slightly broader at apex than near base; slightly inclined cephalad; apical margin evenly convex; apical margin with five bristles, the mid- dle one of which is longer than the first two, the fourth by far the longest, the fifth next longest, and with three additional submarginal bristles below these; with one short bristle on posterior margin. Manu- brium (MB.) as measured from union with ventral margin of P., al- most half again as long as P. is broad; apex curving cephalad. Ninth sternum with proximal arm feebly sclerotized and indistinct. Distal arm of ninth sternum (fig. 20, D.A.9) long, well-developed; arched near insertion of crochet, particularly so at dorsal margin; digitoid in shape, but true ventral portion feebly sclerotized, its margin difficult to see; apex rounded; usually with but three bristles, one proximal, on ventral margin, the second submarginal and inserted near apex of ven- tral arch, the third bristle is subapical and borders what, at first glance, appears to be the ventral margin but in reality is a sclerotized line. With a very coiled long apodemal rod (fig. 19, AP.R.9) arising from angle of ninth sternum. Aedeagal apodeme (fig. 19, AH.A.) about twice as long as endchamber, the limits of which are denoted by the well-developed proximal spur (P.S.) ;apodeme with a long partially coiled apical appendage (AP.A.). Aedeagus with a definite constriction or neck (N.) between proximai spur and aedeagal apodeme. Penis rods (P.R.) extremely long and coiled. Ventral intramural rod (V.I.R.) present. The endchamber dominated by the huge characteristic well-articulated crochets (CR. and fig. 20) which are roughly cleaver-shaped, the blade broad and proximal in position and almost as long as the handle; anterior border with a ventral convexity; apex of crochet expanded, knobbed. Median dorsal lobe (M.D.L.) bifid at apex, its ventro-apical margins acute and asso- ciated on each side with a sclerotized ridge (A.M.S.) probably repre- senting undeveloped apicomedian sclerites. With a conspicuous angulate sinus between end of lateral lobes (Z.L.) and apex of M.D.L. Crescent sclerite (C.S.) long, well-developed; above it on each side an anterior extension of the aedeagal apodeme (AE.A.).

Eemarks.—It is interesting to note that Mr. Hoogstraal collected this species and 7’. breviceps simultaneously from the same set of bats (R.T. #6530). . The British Museum has records of this species from the Philippines, Java, and Borneo. Thaumapsylla breviceps Rothschild 1907 The distinguishing characteristics of the species have been given in the diagnosis of Thawmapsylla longiforceps. The following description lists only other differences, but it should be noted that the chaetotaxy is somewhat variable in both species. The gap in the postantennal row of bristles (fig. 28) is equal to about one-third to one-half of the length of the row. The mesonotum (fig. 27) bears a total of about 22-24 bristles, ignoring the tiny sub- marginal ones. Usually with four apical spinelets on each side of metanotum and first tergum. The most apical of the lateral bristles. of the protibia proximad of midpoint or at level of midpoint. Immovable process of clasper (fig. 30, P.) definitely less than twice as long as broad; dorsal margin with four thin bristles near height of Traub—Fleas Collected in the Philippines 19 convexity; caudal margin straight or slightly concave above acetabular bristles. Exopodite (F.) without submarginal dorsal bristles. Male ninth sternum with distal arm long and narrow, the sclerotized portion distad of the arch more than thrice as long as broad (fig. 31). Aedeagus (fig. 26) with a twisted curved fusiform sclerite (A.S8.7.) dorsad of apex of sclerotized inner tube. Lacking selerotizations characteristics of or suggesting A.M.S. Apicoventral border of median dorsal lobe straight. Crochet (CR) at midpoint more than two-thirds as broad as base, slightly constricted here; apex slightly pointed, inclined down- wards. Female seventh sternum (fig. 29, 7S.) with sinus definitely less in diameter than head of spermatheca; with seven to eleven (usually eight or nine) bristles,two of these usually ventromarginal, Bursa copula- trix somewhat S-shaped.

PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON OCCURRENCE AND IDENTIFICATION OF THE PRAIRIE DEER-MOUSE IN CENTRAL MARYLAND By WittiaM H. STICKEL, Biologist Fish and Wildlife Service U. S. Department of Interior One of the interesting mammalogical phenomena of recent years has been the discovery of Peromyscus maniculatus bairdi at progressively more eastern localities. Osgood (1909) knew this form from no farther east than central Ohio, but by 1942 its distribution in Ohio was reported as statewide (Bole and Moulthrop, 1942). It was reported from the northern panhandle of West Virginia and from northeastern Tennessee by Kellogg (1937, 1939). Mitchell (1934) first re- corded it from northwestern Pennsylvania. Richmond and Rosland (1949) and Grimm and Roberts (1950) found it in all counties of Western Pennsylvania and believed it was spreading eastward via roadsides and cultivated fields. The first record for New York was that of Moulthrop (1938), who trapped bairdw in Genesee County, in the western part of the state. More recently, Hamilton (1950) recorded the appearance of bairdu in 1947 at Ithaca, New York, an area that has been heavily trapped for 20 years. Hamilton also mentioned the capture of prairie deer-mice at North Harrisburg, Dauphin County, Pennsylvania—the first record of bairdiui east of the Appalachian Mountains. The prairie deer-mouse! was unknown in Maryland until 1949, when Lucille F. Stickel and Oscar Warbach live-trapped several in crop fields at the Patuxent Research Refuge, Prince Georges County. These fields are about 1.9 miles north of the village of Bowie. They are situated on a wide bench of sandy clay near the Patuxent River, on the upper part of the Atlantic Coastal Plain. Between May 29 and August 14, 1949, two sexually mature males and three gravid females were brought to the laboratory and caged. The 14 young produced by these females from matings in the wild were reared until about March 1, 1950, when all 19 animals were prepared as skins and skeletons. The litters were then six months two weeks, six months three weeks, and eight months three weeks of age. The 5 adults and 14 young were compared with many specimens of _bairdii in the Biological Surveys collection from various localities in . the Middle West. No cranial, mensural, or color differences were ob- 1Common names used follow the excellent suggestions of Dice (1937). 2—Proc. Brow. Soc. WASH., Vou 64, 1951 (25) APR 1.3 1951 26 Proceedings of the Biological Socrety of Washington served. Indeed, the Patuxent specimens could not have been picked out if mixed with certain Middle Western series. After the first bairdii was tentatively identified, all Peromyscus (except the five brought to the laboratory) were carefully examined, measured in the field, ear-tagged, and released where caught. Recap- tures often permitted more certain identification. Field identifications were checked by comparing measurements with those of known speci- mens, with the age of the individual in question being considered. Doubt remained about very few released animals. ECOLOGY The prairie deer-mouse seems to be precariously established at the Refuge. In the year from May 1949 to June 1950, 23 bairdwi were captured by Mrs. Stickel and Mr. Warbach in connection with population and farm wildlife studies. Fourteen were females and nine were males. Only six were considered juveniles. Deer-mice were at no time common in the fields and did not appear to increase in number. ‘They were far outnumbered by feral house-mice (Mus musculus) oceupying the same habitat. Deer-mice were most often caught in corn and in young wheat, both relatively open habitats. Here several individuals had good recapture histories and are known to have bred. Deer-mice were trapped only occasionally in hay or tall wheat. This is in accord with the well known preference of bairdiw for open, rather exposed sites. Released individuals were often followed to burrows in nearly bare fields. We do not know if bairdiw has spread to any uncultivated habitats of the Refuge, but few if any seem suitable for this mouse. It has been found in but one set of adjoining fields, and is not known to have reached the other farm on the Refuge. P. m. bairdii may not be securely established in this locality, but it definitely is reproducing. All but one of the females were in some stage of breeding whenever caught. Evidence from dates of appearance of very small juveniles, and from the condition of frequently retrapped females, indicates that litters were born in early April, May 1, Septem- ber 11, and early November. The three caged females bore their litters June 15, August 7, and August 17. Their litters consisted of 6 (one died), 5, and 4 young. Nine of the survivors were males, five females. It would be interesting to know when and how the local bairdu population arrived. Although the species was not found here before 1949, it could have occurred in its present small numbers without being noticed, for there was little trapping in crop fields, and an occasional bairdit could have passed for a young noveboracensis. It-is equally difficult to say how this deer-mouse got here. No doubt the animal is expanding its range by natural means in consequence of artificially created habitats, but the possibility of accidental transportation is con- .Siderable. The wide dispersal of the house-mouse is an excellent example. Mice can easily be carried with grain, plants, or other items. We know of instances of mice living in passenger cars for long periods, and they should live equally well in freight shipments. It may be significant that the fields in which bairdii has been found on the Refuge are near two equipment barns, a paved road, and a private farm. Stickel—Prainie Deer-Mouse in Maryland ot SEPARATION FROM PEROMYSCUS LEUCOPUS NOVEBORACENSIS Now that the enviable situation of having but one type of Peromyscus no longer exists in this part of the East, local biologists are faced with the necessity of being able to separate P. m. bairdui and P. |. noveborac- ensis—not only in the laboratory, but, insofar as possible, in the field. A comparative study of prepared local specimens was made as a basis for both laboratory and field identifications. It was soon found, how- ever, that field measurements of living mice, made by Lucille F. Stickel, differed slightly from those of freshly killed specimens although the same methods of measuring were used. The differences presumably reflect not only individual variation of the specimens, but also the difficulty of getting identical measurements of living and dead mice. The field measurements are therefore considered separately. They may prove more useful to workers doing live-trapping than will the other data, particularly since they include measurements of juveniles. Only speci- mens from the Patuxent Refuge were used in either set of data. It is not anticipated that the results will hold for other regions, or for every specimen from this region. Young bairdii and fully adult noveboracensis are generally recognized as such. The difficulty lies in distinguishing juvenile or subadult wood- mice from subadult and adult prairie deer-mice. A few of our speci- mens suggest that the greatest trouble comes from fall-born noveborac- ensis that fail to attain the usual size during the winter although they are of adult or subadult age and pelage. One individual of this sort began growing again in the spring. It is extremely easy to misidentify such individuals in the flesh. Before attempting identification of ques- tionable specimens, it is desirable to determine age as well as feasible by such indicators as pelage, known history of live-trapped animals, or in the laboratory by tooth wear or ankylosis of epiphyses. Measurements of total length, tail, and hind foot were made by stand- ard methods. The ear (from notch) was measured in its natural posi- tion, neither stretched nor straightened. Cranial measurements were made with vernier calipers. Condylo-incisive length was measured from the front of an upper incisor to the rear of the occipital condyle of the same side. Cranial breadth was measured at the lower ends of the lateral lobes of the parietals, with jaws of calipers held longitudinally along the skull. Length of maxillary tooth row is crown length. The figure compares variation of freshly killed specimens of both forms in some of the more diagnostic measurements. Length of hind foot is probably the most useful measurement, not only because of its diag- nostic value, but also because adult length is attained relatively early in life. The series shown on the graph do not overlap in length of foot, but overlapping certainly would occur in larger series. The following tabulation of field measurements of living mice supplements the graph. Overlapping at 19 mm. will be noted. Four subadult to adult mice of each form had feet of this length.

Measurements taken from skin labels, however, must be used with discretion: some of the greater noveboracensis ear lengths plotted in the figure were measured by preparators other than the writer and may have been made with ear pulled straight. Measurements of ears of living mice apparently run one or two millimeters lower than those of freshly killed mice. Our field measurements are thus lower than those of figure 1, but seem equally diagnostic: - Young Adults and Juveniles and Subadults Adults No. Range Av. No. Range Av.

Tail lengths of the two forms also overlap, but the measurement is frequently of value, especially if the approximate age of the individual is known. Part of the overlapping is caused by the increase of tail length until full growth of the individual is reached. Another part of the overlapping is independent of age. For example, the upper limit for adult bairdi and the lower limit for adult noveboracensis occasionally overlap at about 65 mm., to judge from both field and laboratory data. Field measurements of gray juveniles of different sizes show tail lengths of 40 to 53 mm. for seven bairdii, and lengths of 54 to 76 mm. for twelve noveboracensis. The other field measurements are similar to those of the graph, except for a young adult bairdit with a tail of 50 mm. and a subadult noveboracensis with a tail of 60 mm. Total length is of little use in the present connection, as it is of diag- nostic value only for large or small individuals about which there is sel- dom any real question. Cranial breadth reflects the greater size of the brain case in noveborac- ensis better than does cranial depth. The difference between these two mice in size of brain case is often obvious in direct comparison, and is apparent early in life. Condylo-incisive length of skull is chiefly a function of the greater size of noveboracensis. It is of diagnostic value in the present series except for a few young noveboracensis. Length of maxillary tooth row will nearly separate the two series. It is free of age variation once all teeth are erupted, except that individ- uals with much worn teeth may have a slightly shorter crown jength than younger individuals. Length of tooth row is of particular interest be- cause it should make possible accurate determination of the remains of many individuals in predator stomach and scat material. Shape of the incisive foramina is one of the best characters. These foramina are anteriorly constricted in noveboracensis, open and evenly curved anteriorly in bairdii. This is true of all our bairdii. One of our | noveboracensis has the bairdii condition, and another is intermediate in this respect. This character also should be of value in dealing with food habits materials. Stickel—Prairie Deer-Mouse 1n Maryland 29 The greater hairiness and sharper bicoloration of the tail of Dairdiw are relative characters of secondary importance. They cannot be wholly relied upon, but are of use in combination with other characters. Young noveboracensis may have short, bicolor tails that are as hairy as those of many bairdii. Coloration is of very little value. When our series are compared, bairdii averages grayer, duller, and less yellowish on the sides, but some individuals are as bright as many noveboracensis. Few specimens other than old red wood-mice could be properly determined by color alone if the series were mixed. Minor color characters, such as white ear tufts, dorsal stripe, rufous rump, color of snout, and others that have been mentioned by various workers, seem more misleading than helpful. Shape of head of living individuals (see Burt, 1946, p. 204, fig. 94) is of use to workers thoroughly familiar with the animals in life, but im- presses us as very difficult to use accurately. Our approach to identifying these mice in the field is to ascertain. the age of each individual as well as possible, and to take measurements of hind foot, ear, and tail. MHairiness and bicoloration of tail and shape of head are also considered. Measurements of questionable individuals are compared with tabulations of field measurements of representative age series of local mice of each form. Frequently some one measurement will conclusively decide an otherwise difficult identification. The tail or the ear may be too long for a juvenile to be bairdii, or the foot may be too short for a subadult to be noveboracensis.. We believe that a degree of accuracy adequate for most field problems can be attained rather - quickly in this way. Repeated captures of troublesome individuals may also be highly informative: mice tentatively listed as bairdii have grown up to be easily identified noveboracensis. Habitat is not relied on in making identifications, for we have often found wood-mice well out into fields. It is to be expected that some identifications will be probable rather than positive, and that certain individuals cannot be determined in the field at all. This will be especially true, of course, in parts of the coun- try where many specimens cannot be identified satisfactorily even in the laboratory. U. §.

TAYLOR A group of Central American frogs, at the present time placed in the genera Centrolene and Centrolenella, have for some time been of considerable interest to me, and I pro- posed this year to examine the material in the various Ameri- can museums with a view of revising the group. At the pres- ent time specimens of these genera in certain museums are not available so I am delaying my attempt to review the entire eroup until such time as the material may become available. At this time I propose two new genera for species already established, and propose a family status for these small frogs. The genus Centrolene was established in 1872 by Jimenez de la Es- pada for C. geckoidewm from the Rio Napa, Ecuador. This species is eharacterized chiefly by the presence of a process or hook growing out from the humerus in the males, and the presence of vomerine teeth. In females there may be some evidence of this humeral modification if the arm is somewhat dessicated, but I believe it is not otherwise visible ex- ternally. While the teeth are normally present they may be sometimes absent. The length of this species far exceeds any other belonging to this group of genera. While the length of the type is not given, a specimen examined has a length of 57mm. A species of small frogs from near Limén on the Caribbean side of Costa Rica was described by Boettger as Hyla prosoblepon. This was later referred to the genus Centrolene by G. K. Noble.! It agreed in general with the characteristics of that genus. A distinct humeral hook was present in males of the genus (absent in females) and vomerine teeth were likewise present.2 It differed very greatly in size and gen- eral appearance. Since the skeletal structure of C. geckoideum has not been studied it is not impossible that when the anatomy of these forms is better known they may be separated generically by other characters. Certain other species may also belong with Centrolene prosoblepon. Noble (loc. cit.) has suggested that Hyla ocellifera Boulenger? from northwest Ecuador is a member of the group but did not specifically place tAmer. Mus. Nat. Hist. Bull., vol. 42, 1920, p. 442; and Proc. Biol. Soc. Wash- ington, vol. 37, 1924, pp. 66-67. 2The teeth are absent in a specimen taken with several others on the eastern slope of Volcfin Pods, Costa Rica. In 22 specimens I have examined from an elevation of from 4000 to 5500 ft. elevation in Costa Rica, the teeth were present in all but one. Noble has mentioned that the teeth on the vomers may be absent, but this may be regarded as an infrequent exception. Similar loss of teeth is known to occur in certain species of Hyla and Syrrhophus in Mexico. In very young specimens of many frogs the teeth may be absent because they have not yet erupted. 3Ann. Mag. Nat. Hist., ser. 7, vol. 3, Apr. 1899, p. 277, pl. 12, fig. 4. 3—Proc. Bion. Soo. WASH., Vou. 64, 1951 (33) APR 13 1951 34 Proceedings of the Biological Society of Washington it in a genus. Im this species the vomerine teeth are present but no men- tion is made of the humeral characteristics. J suspect that the type is a female (no mention being made of the vocal sae or vocal slits) in which case the hook would normally be absent. Proper placing of this form awaits further data on males. Noble (loc. cit.) proposed the genus Centrolenella for a species of this group which he described under the name of Centrolenella antioquiensis, from a locality 14 mi. N. of Mesopotamia, Dept. Antioquia, Columbia. He had available one adult female, and two males of which one was adult. He states, ‘‘closely related to Centrolene from which it differs in the absence of vomerine teeth and humeral spines.’’ Most of the other generic characteristics mentioned are likewise characteristic of Centro- lene. An examination by me in 1949 of the type and paratype specimens of C. antioquiensis seems to throw a different light on the matter. The adult paratype (so labeled) has well-developed humeral hooks and is presumed to be the adult specimen mentioned by Noble along with the type description. While the absence of this character is mentioned in the generic diagnosis, no further comment is made regarding the pres- ence or absence of the hook, in the specific description. There was no evidence that any substitution of specimens had taken place. I returned to the American Museum in the summer of 1950 to continue my study of the group but the paratypes of the species could not be located at the time of my visit. Inasmuch as the most salient generic character given for the genus Centrolenella as separating it from Centrolene is actually present in the male of the type species (the presence of the humeral hook in the males), and the remaining character of the vomerine teeth is somewhat variable, I shall regard Centrolenella a synonym of Centrolene. This action leaves the numerous species that have been described under the genus, or later referred to it, without a generic name. Honoring Dr. Doris Cochran of the United States National Museum, I propose for these the name, Cochranella gen. nov. Genotype. Centrolenella granulosa Taylor. This genus is characterized by the absence of the humeral hook or process in both sexes, absence (generally) of the vomerine teeth, with- out a free tip or sharp protruding spine on the pollical rudiment; toes webbed, with usually some webbing on the hand; terminal digital discs either transversely oval or subtriangular; a rather large palmar tubercle; no omosternum; a small cartilaginous sternum; pupil horizontal; ostia pharyngia present; the tympanum exposed or absent; a broad thin anal flap; pigment appearing in recently preserved animals, lavender to pur- ple and confined to head and dorsal surfaces; vocal slits in males; astragalus and caleaneum fused into a single element. Forms belonging or presumably belonging to this genus are: Cochranello eurygnatha (Lutz) Cochranella fleischmanni (Boettger) Cochranella colymbiphyllum (Taylor) Cochranella granulosa (Taylor) ican Frogs BY) Cochranella pulverata (Peters) Cochranella uranoscopa (Miller) Cochranella viridissima (Taylor) Cochranella valeriot (Dunn) Cochranella albomaculata (Taylor) Cochranella buckleyt (Boulenger) Cochranella parambae (Boulenger) Cochranella chrysops (Cope) Cochranella parvula (Boulenger) —S sD A species of small frog related to the preceding genera differs marked- ly in having a large pollical remnant with a free tip, and bearing a sharp protruding spine in the male. It appears to stand in relation to Cochranella, as Plectrohyla does to Hyla. I propose for it the generic name Teratohyla gen. nov. Genotype: Centrolenella spinosa Taylor. Characterized by the presence of a considerable pollical remnant with a free tip, and bearing a protruding spine in the adult males (present in females but less developed, the spine being entirely concealed). Vomerine teeth absent. Other characters as in Cochranella. The species, Teratohyla spinosa occurs in the lowlands of Costa Rica and Panam4é Canal Zone. In the latter locality it has been mistaken for another species. The status of Hylella parambae Boulenger (parabam- bae) is in question. It is not impossible that it may prove to represent a second species of this genus. The group of frogs considered under the preceding genera has long been puzzling to herpetologists. Noble in his discussion (loc. cit.) has pointed out the isolated position that it holds. He thought that certain of the characters pointed to the family Leptodactylidae (which he later united with the Bufonidae) and certain of the characters pointed to the Hylidae. However he maintained them with the former group. Boulen- ger has associated species that he knew, with the Hylidae. Nieden in his Das Tierreich, Anura I, has regarded them as hylids. Smith and Taylor in their Mexican Catalogue placed them in the Hytiee without adequate investigation. What I now regard as one of the most significant characters in this group of frogs, (and for that matter in the whole order), is one that previous workers have seemingly overlooked. This is the complete fusion of the bones in the third (tarsal) joint of the limb. This fusion is such that there is little superficial evidence that two bones are involved. In 1941 I revived Cope’s family name, Pelodytidae, for the living frogs known to have a fusion of the tarsal elements, having an arciferal pectoral girdle, procoelous vertebrae, a bony style in the sternum, the coceyx articulating by a double condyle, lacking the terminal processes on the ultimate phalanges of the digits, and the intercalated cartilages. Since the frogs here under consideration differ in all these characters from the Pelodytidae save in the condition of the astragalus and ¢al- caneum, coccyx and vertebrae, I am proposing to give the group a family status, the name for which will then be 36 Proceedings of the Biological Society of Washington Centrolenidae, family novum. The characteristics are: arciferal pectoral girdle; omosternum ab- sent; sternum small cartilaginous; nine procoelous vertebrae; sacral diapophyses distinctly dilated; most terminal phalanges T-shaped; all digits with an intercalated cartilage between penultimate and ultimate phalanges; femur with a thin ridge near the acetabular articulation; coccyx articulating by a double condyle; digital formula of hand, 152,2,3,05 0f Loot 2,252,4,3. These small frogs are secretive and are difficult to capture unless one finds them breeding. In consequence except for a very few species they are rare in collections. Since the territory comprising Costa Rica and Panama has some ten described species representing three genera, one may anticipate that when the fauna of South America becomes well explored a large series of species with perhaps still other genera will be made known. J am aware of at least a dozen undescribed forms already in American museums masquerading under incorrect names. Furthermore I regard it as strongly probable that certain African frogs, especially those now recognized in the subfamily Heleophryninae belong in the family Centrolenidae. Workers having available material of this group would do well to examine the condition of the limbs and to compare other structures with this family. LITERATURE CITED Boettger, O.

G. DrEIgGnNAN* The hawk-owl, Ninox scutulata, has hitherto been consid- ered a mere winter visitor to the Philippine Islands, but study of specimens in the collections of the United States National Museum, the American Museum of Natural History, the Chi- eago Natural History Museum, the Museum of Comparative Zodlogy, and the Peabody Museum of Natural History at Yale University (to the authorities of all of which my thanks are hereby given), has shown that a very distinct race is resident at least in the southern portions of the Archipelago. The new form may be called Ninox scutulata randi, subsp. nov. Type.—vU. S. National Museum No. 200,878, adult female, collected at Catagdan (elev. 1,100 ft.), at the base of Mount Malindang, Misa- mis Province, Mindanao Island, on May 23, 1906, by Edgar A. Mearns (original number 14,196). Diagnosis.—Nearest Ninozx sc. japonica (Japanese Islands) in the dark reddish chocolate of its upper parts (with the pileum scarcely differ- entiated from the mantle), the rufescent-tinged bands on the rectrices, and the preponderance of chestnut over white on the under parts, but everywhere even darker and redder than japonica, and easily distin- guished from this and all other known races by its much more robust bill and much larger toes and claws. Remarks.—Specimens of N. sc. randi have been seen from the follow- ing localities: Mindoro, 1 unsexed, July 3; Ceba, 1 male, June 18; Min- danao, 2 females, May 23, June 17; Basilan, 2 males, April 10, no date. Although I am in agreement with those recent authors who have allo- cated Rafiles’s name scutulata to the race resident in Sumatra and Malaya, I do not stand with them in considering the name japonica applicable to populations of Korea and China, which differ from true japonica in their rather paler upper parts, more gray-brown (less rufescent) tail bands, and the greater proportion of white to chestnut on the under parts. It is probable that Chinese birds must be called Ninox scutulata florensis (Wallace), from Athene florensis Wallace (Proc. Zool. Soc. London, for 1863, pt. 3, Feb. 1864, p. 488: Flores). A form of the species is resident on some of the small islands between Formosa and Luzon.

C. Hortrres AND L. P. WEHRLE Herewith we describe two new species of Aphididae from Arizona. Schizolachnus tusoca new species Alate viviparous female. Size and general color.—Length from vertex to tip of anal plate 2.35mm. Data on color not available. Head dusky brown with anterior margin considerably darker. Prothorax concolorus with head. Meso and metathorax dark brown. Abdomen in life perhaps pale green or very light dusky, with cornicles, small areas around the spiracles, cauda and anal plate light dusky. Antennal segment I and JI slightly lighter in color than the head, segments III and IV pale dusky with distal portions darker, segment V and VI slightly darker than segments IIT and IV with distal portions darkest. Femora, with exception of extreme base dark brown. Pro and metathoracic tibiae dark dusky brown almost uniform in color throughout. Mesothoracic tibiae light dusky with dis- tal portions darker. Tarsi dusky brown. Head and thorax.—Head with median longitudinal suture present but indistinct. Comparative lengths of antennal segments as follows: III 443mm., IV .171mm., V .171mm., VI .114 + .028mm. Secondary sen- soria confined to third antennal segment numbering four to five, arranged in a straight row, small, and hardly tubereulate. Segment III smooth except for apical portion, remaining segments lightly imbricated. An- tennal hair sparce for genus, somewhat inclined. Majority of hair on III distinctly less than two times width of segment in length. Rostrum short, reaching less than half-way to mesothoracic coxae. Hair on anterior margin of head suggestive of that on dorsum not longer than that on antennae. Hair on prothorax shorter and somewhat thicker than that on remainder of thorax. Stigma light dusky with a pro- nounced scale-like surface. Media once branched. Surface of wing very rough, with the seale-like structures for the most part sharp pointed and when seen from the side suggestive of hair. Pro and mesothoracie femora provided with fine hair which is shorter than the width of the segment. The hair on the metathoracic femora is most unusual. That on the inner margin being very short and dull pointed, almost peg-like and equal to about one-third of the width of the segment in length. The hair on the outer margin of the femora is fine and about half the width of the segment in length. Hind tibiae 2.28 mm. in length, provided with thick spine-like hair which is rather dull poimted. The hair on the inner margin is shorter than that on the outer margin. The hair at the apex of the tibiae is 5—Proc. Brow. Soc. WASH., Vou. 64, 1951 (43) APR 1 3 1951 44 Proceedings of the Biological Society of Washington longer than that which is more proximal. Metathoracic tarsi .40mm. long. The first tarsal segment is provided with a few hair, perhaps ten to twelve, these are all of one kind and all are directed to the same direction. Second taral segment provided with a few very long, fine, sharp pointed, drooping hair. Abdomen.—Cornicles approximately .028mm. high. Base of Corni- cles about 0.71mm. with only one hair a condition which is hardly typical of the genus. The rim of the cornicles shows considerable flare. Dor- sum of abdomen with comparatively few coarse short hair and these for the most part arranged in transverse rows. The row being rather well defined towards the posterior, there being five distinct rows from the cauda forward and two less distinct rows forward of these. Ventral sur- face of abdomen with fine long irregularly arranged hair. The cauda and anal plate are characteristic of the genus as regards shape, both are provided with two kinds of hair, a very long slightly curved, coarse type on the margins and a decidedly shorter and much finer type on the dorsum. Apterous viviparous female. Size and general color—Length from vertex to tip of anal plate 2.38mm. Width of head through the eyes. 457mm. Color approximately that of alate viviparous female with head, thorax and legs slightly darker. Head and thorax.—Comparative lengths of antennal segments as fol- lows: III .347mm., 1V .128mm., V .143mm., VI .1 + .028mm. There are no secondary sensoria. In other respects the antennae are sugges- tive of the alate viviparous female. Rostrum exceedingly short, just failing to reach the coxae of the mesothoracic pair of legs. Occular tubercles present but not well developed. Hind tibiae 1.85mm. long. Hair on inner and outer margins of tibiae approximately the same in quality rather dull at the tip, and for the most part but little more than half the width of the tibiae in length. Hind femora as in alate vivi- parous female. Length of hind tarsi .347mm. with the hair similar to that found in alate viviparous female. Abdomen.—Cornicles lower than those of alate viviparous female with the base not much larger than the width of the cornicle at the apex. Width of base of cornicle about .07mm. height of cornicle about .028mm. Outer rim of base of cornicle irregular and somewhat indistinct. Rim of base of cornicle associated more or less with from one to three hair. Rim of cornicles near apex poorly developed, and non flaring. Cauda and anal plate as in alate viviparous female. The cornicles of this form could perhaps be best described as almost ring-like. It is strange that they differ from those of the alate form. Holotype alate viviparous female mounted one same slide with the apterous viviparous female which is made morphotype. This slide has been deposited in the United States National Museum. Data associated with this species: Host Pinus arizonica. This species of pine is consid- ered by some to be a variety of Pinus ponderosa. Chiricahua Mountains, Arizona, 8,000 ft. elevation. June 23, 1933, by O. Bryant. : This species does not fit well the genus in which it is being placed, as that genus is now conceived. For example the cornicles of the apterous Hottes-Wehrle—New Species of Lachmni 45 viviparous female can hardly be referred to as shallow hairy cones, nor can those of the alate form be considered hairy. There are objections to placing the species in the genus Hulachnus as characterized by Baker. Dr. Borner has recently described as new, several species which he has placed in the genus Hulachnus. Some of the species described by Dr. Borner can hardly be considered as belonging to the genus Hulachnus in the sense that Baker thinks of it. For example at least one of the species has minute hair on the vartex and antennae and another has the cornicles on shallow but not hairy cones, all however have long hair on the dorsum of the first segment of the tarsus in common with the type of the genus EHulachnus which is Lachnus agilis Kalt. Schizolachnus tusoca differs from Schizgolachnus pini-radiatae (Davidson) by the shorter hair on the antennae and legs, by the almost peg-like hair on the inner margin of the metathoracic femora, by the darker legs, and fewer hair associated with the cornicles. It agrees with pini-radiatae in the lack of long hair on the dorsum of the first segment of the tarsus. Baker in his Generic Classification of Aphididae places the genus Schizolachnus in the Sub- tribe Lachnina. This seems strange. It would appear more logical to place both the genus Schizolachnus and the genus Unilachnus in the Subtribe Hulachnina and emphasize the obtuse rostrum so characteristic ef other Eulachnina. When so placed the genus Hulachnus differs from the genus Schizolachnus most conspicuously by the presence of hair on the dorsum of the first segment of the tarsus and the more feebly devel- oped occular tuberclese; factors hardly sufficient to differentiate genera. . The deseription of the genus Hulachnus was published in 1909 as was that of the genus Schizolachnus, despite the fact that both works in which the two genera were described bear the date 1908. The genus Eulachnus was described on p. 329, and the genus Schizolachnus on p. 375. The genus Hulachnus would therefore have page priority should it not be possible to determine the actual mailing date of the two publica- tions were one to combine the two genera. Cinara tonaluca, new species Apterous viviparous female. Size and general color—Length from vertex to tip of anal plate vary- ing from 2.14-2.57mm. with larger sizes predominating. Width of head through the eyes .57-.62mm. Data on color not available the specimens having been cleared and strained. General color of head thorax and ab- domen apparently the same, ostensibly light. Antennae dusky. Segments four and five of rostrum dark brown, third segment more or less spotted. Femora quite uniformally dusky-brown. Tibiae apparently pale except for apical region which is concolorous with tarsi which are dusky brown. The spiracles appear to be surrounded by small brownish areas similar to the base of the cornicles. Cauda dusky brown as is a small area just anterior to it. Dorso lateral area of abdomen with a few small brown spots. These suggest wax glands. Head and thorax. Relative length of antennal segments as follows: JIT .21-.27mm. with the longer lengths predominating, IV .10-.128mm., V_ .128-.171mm. always longer than IV, VI .057-.085 + .042-.057mm. Secondary sensoria one, confined to middle of segment V rather small and only slightly tuberculate. Antennal hair rather sparce, that on 46 Proceedings of the Biological Society of Washington anterior margin longest, being about half again as long as the segment is wide. Hair on third antennal segment very upright that on remain- ing segments slightly more inclined but still forming a large angle with side of segment. All segments smooth except unguis. Rostrum long, almost reaching base of cornicles. Hind tibiae .75-1.14mm. long, each measurement representing a single extreme case, aS a rule more than 1.01mm. Hair on outer margin of tibiae slightly longer than width of tibiae very upstanding, inner hair on hind tibiae finer, somewhat shorter and more inclined. The hair near the apex of the tibiae more inclined than that above. Hind tarsi .185-.214mm. in length. First tarsal seg- ment with 7-9 hair. Abdomen.—Abdomen clothed with many rather long hair. Base of cornicles varying from .10-.114mm. provided with one kind of hair. Cauda rather shallow. Alate viviparous female. Size and general color.—The length from vertex to tip of anal plate varies from 2.28-2.43mm. Data on color not available but apparently similar to that of apterous viviparous female. Head and thorax.—Antennal segments with the following comparative lengths: IIT .286-.30mm., IV .128mm., V .143-.157mm., VI .071 + .042 mm. Secondary sensoria limited to one or less on III and one on V. Both sensoria are small and only slightly tubereculate. Hair on antennae similar to that on apterous viviparous female. Rostrum as in apterous viviparous female. Hind tibiae 1.17-1.22mm. long. Hair on hind tibiae shorter than that in apterous viviparous female, being subequal to width of segment and slightly more inclined than that of the apterous form. Hind tarsi .21-.228mm. long. First tarsal segment with as many as ten hair. Media of fore wings twice branched, second branch of media closer to margin of wing than to the first branch. Media and branches very faint. Stigma rather dark, scale-like. No veins reach the margin of the wing. Abdomen.—Base of cornicles about .128mm. wide. Height of cornicles about .071mm. Abdomen with numerous long sharp pointed hair. Sur- face of abdomen very finely imbricated. Cauda and anal plate as in the apterous viviparous female. Holotype alate viviparous female. Morphotype apterous viviparous female. Holotype and morphotype mounted on the same slide, which has been deposited in the United States National Museum. There are sev- ral paratypic slides. Host Juniperus monosperma. The material was collected by L. P. Wehrle at Tucson, Arizona, July 13, 1943. This species ‘keys to the first FF couplet page 845 in Gillette and Palmers key, Annals Entomological Society of America vol. XXIV ex- cept that rostrum is shorter than the body. From Cinara pulverulens it differs in host, sensoria, and length of hair on the hind tibiae in alate. From Cinara fornacula it differs in host, size, and character of hair on hind tibiae. From Cinara juniperensis it differs in specific host, sen- soria, media and in the size of the base of the cornicles, length of hair on the hind tibiae and their angle. Vol. 64, pp. 47-54 oe tnd | April 13, 1951 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON ARIZONA APHIDIDAE By F. C. Horres anp W. P. WEHRLE The species of Aphididae described herewith are from the extensive collection of slides of that family brought together by Dr. Wehrle. This is the first of a projected series of papers on the Aphididae of Arizona. Unfortunately Dr. Wehrle died while this paper was in process in the hands of the senior author, who takes this opportunity to express his loss of a very able colleague whose untimely death prevented him from pub- lishing much from his extensive investigations. Wapuna new subgenus. Similar to the genus Aphis except that the anterior margin of the head is somewhat broader and more flattened, and apparently the entire lack of the anal plate in the apterous viviparous female, and the very shallow and minute anal plate in the alate viviparous female. Type Wapuna tahosalea new species. Aphis (Wapuna) tahosalea new species. Apterous viviparous female. Size and general color.—Length from vertex to tip of abdomen vary- ing from 1.11-1.57mm. The smaller sizes are more numerous. Data on color not available the mounted specimens having been cleared and stained. Color apparently pale, perhaps yellow or pale green with the head and thorax more or less light dusky. Antennae pale dusky, legs pale except for the apical portions of the tibiae and tarsi which are light dusky-brown. Cornicles, cauda, and spot anterior to cauda light brown. Apical segment of abdomen brown, this at times takes on the appearance of a pseudo anal plate. Head and thorax.—Comparative lengths of antennal segments as fol- lows: III .21-.286mm., IV .14-.18mm., V .15-.17 mm., VI .10-II + .24mm. There are no secondary sensoria. All antennal segments imbri- cated the imbrications being rather well developed. Antennal hair very sparce and less than one half of the width of the segment in length. Median anterior margin of head flat, with lateral portions somewhat raised suggesting low lateral tubercles, these are far removed from the first antenal segment which is well developed and almost out of propor- tion to the rest of the segments. The rostrum is extraordinarily long always extending well beyond the metathoracie pair of coxae to the mid region of the abdomen and in some cases almost to the base of the cornicles. The last segment of the restrum is subequal to the length of the cauda. The prothorax is provided with a pair of lateral tubercles. The hind tibiae vary from .57-.78mm. in length. The hind tarsi are 6—Proc. Biov. Soc. WasH., Vou. 64, 1951 (47) APR 1 3 1951 48 Proceedings of the Biological Society of Washington 10mm. in length. The hair on the outer margin of the hind tibiae is much sparcer and shorter than the hair on the inside margin. On the proximal third of the tibiae the hair are very scarce. Abdomen.—The surface of the abdomen is imbricated. Lateral por- tions of the abdomen with few if any hair, these when present short and fine. Dorsum of abdomen with a few scattered long sharp pointed hair, these have their origin from small surface elevations. First abdominal segment with a pair of lateral tubercles, there is a similar pair pos- terior to the cornicles. Cornicles .17-.25mm. long, rather wide at the base, tapering to a poorly developed rim at the apex. The inner margin of the cornicles is almost straight the outer margin is slightly curved. The cornicles are coarsely imbricated. Cauda .128mm. long. The cauda is constricted just anterior to the middle, as a rule it has two strongly incurved hair on a side, its surface is setulose. Anal plate apparently absent. The posterior margin of abdomen with a few well developed hair. Alate viviparous female. Size and general color.—Length from vertex to tip of abdomen vary- ing from 1.25-1.78mm. With the smaller sizes more abundant. Width of head through the eyes. 32mm. Data on color not available, probably light green or yellow, with small dusky areas at sides and a few similar smaller ones on the dorsum. Dusky areas just anterior to base of corni- eles largest. Area just anterior to cauda more or less dusky. Cornicles and cauda brown. Head and thorax light dusky. Color of legs and antennae similar to those of apterous viviparous female. Head and thorax.—Proportional lengths of antennal segments as fol- lows: III .214-.286mm., IV .157--17mm., V .14-.17mm., VI .10-.11 + .24-.25mm. Secondary sensoria confined to a row on third segment, large, with wide rims, far apart, extending throughout length of seg- ment. Antennal hair sparce, ultra short and fine. All antennal seg- ments imbricated. Anterior margin of head broad and flat except for median tubercle. Rostrum long extending to or beyond middle of abdo- men, often almost reaching to base of cornicles. Second branch of media much closer to margin of wing than to the first branch. Pro- thorax with a pair of lateral tubercles. Abdomen.—Imbrications and hair similar to those on apterous female. Apparently no lateral tubercles on the first abdominal segment. Tu- bercles posterior to the cornicles very small. Cornicles .11-.14mm. long, less wide at the base than those of the apterous female. Cauda .128mm. long constricted near middle with two pair of strongly incurved hair. Anal plate almost absent and always difficult to determine. Holotype slide with alate and apterous viviparous females deposited in the United States National Museum. This species was collected on Bryophyllum pinnatum by L. P. Wehrle Jan. 10, 1944, at Tucson, - Arizona. Because of the strongly incurved hair on the cauda, the shape of the cauda, and the secondary sensoria a quick glance at this species suggests Aphis gossypii Glover, from which it can be separated at once by the longer rostrum and the absence or poor development of the anal plate. Hottes-Wehrle—Arizona Aphididae 49 Aphis piutapa, new species Apterous viviparous female. Size and general color.—Length from vertex to tip of anal plate 1.31 mm. width of head through the eyes .35mm. Data on color not available. Head thorax and abdomen apparently the same color and free from duskiness. Most likely color light green. Antennae pale with the ex- ception of the apical portions of segments V and VI which are light dusky. Legs light dusky with the apical portions of the tibiae and all of the tarsi darker. Cauda and cornicles pale dusky. Head and thorax.—Proportional lengths of antennal segments as fol- lows: III .2imm., IV .20mm., V .20mm., VI .085 + .057mm. Third an- tennal segment very lightly imbricated, segments IV V and VI pro- gressively more so. Antennal hair almost absent, very fine, and ultra short. There are no secondary sensoria. Anterior margin of head broad and rather flat, provided with four short hair. The rostrum reaches the coxae of the metathoracic pair of legs. Tibiae with very fine short and exceedingly sparce hair on proximal three fourths. Hair on apical fourth longer but still sparce. Length of hind tibiae .757mm. Length of hind tarsi .128mm. Prothorax with a pair of lateral tubercles. Abdomen.—Abdomen apparently without lateral tubercles. Surface of abdomen very faintly imbricated. Abdominal hair almost absent, very fine and extremely short. Cornicles .085mm. long feebly imbricated with the sides very slightly curved. Rim at apex of cornicles poorly devel- oped. Cauda longer than the cornicles measuring .157mm. in length, very slightly constricted near middie, sides with three hair. The cauda has a well developed setulose surface. Anal plate broadly rounded. Alate viviparous female. Size and general color.—Length from vertex to tip of anal plate 1.31 mm. or equal to the length of the apterous viviparous female. Width of head through the eyes .348mm. Data on color not available. Head and thorax brown. Antennae dusky, fomora dusky-brown, tibiae dusky with apical portions and tarsi dusky-brown. Cornicles pale dusky. Cauda dusky except for a clear area near base. Head and thorax.—Comparative length of antennal segments as fol- lows: III .214mm., IV .143mm., V .128mm., VI .085 + .057 mm. Secon- dary sensoria limited to the third antennal segment, irregular in size, arranged in a straight but very much crowded row on apical two thirds of segment. The secondary sensoria number eight to ten. The third antennal segment is comparatively smooth, remaining segments dis- tinctly imbricated. Antennal hair almost absent and so fine and short that it is difficult to see. Rostrum just reaching coxae of metathoracic pair of legs. Anterior margin of head rather broad and flat, provided with four fine hair. Prothorax with a pair of lateral tubercles. Second branch of media much closer to margin of wing than to first branch. Veins of wings pale dusky. Stigma long and narrow, dusky in color. Hind tibiae .77mm. long. Hair on hind tibiae if anything more sparce than that on apterous viviparous female, in other respects much the same except that it is not longer at the apex. Abdomen.—Segment posterior to cornicles provided with a pair of 50 Proceedings of the Biological Society of Washington very small lateral tubercles. Hair on abdomen almost absent, very short and fine. Cornicles .057mm. long, slightly imbricated the sides almost straight, the rim is poorly developed. The cauda is .128mm. long or much longer than the cornicles, its surface is setulose, it is slightly con- stricted just before the middle. There are three hair on one side and two on the other. The anal plate is similar to that of the apterous viviparous female. The uncommonly short unguis and the fact that the cornicles are much shorter than the cauda separate this species at once from most other species of the genus Aphis. This condition prevails in Aphis minutis- sima G. & P. but in this species segments four and five of the rostrum are conspicuously slender and the cornicles and cauda differ. Because of the short unguis this species is also suggestive of Aphis tetrapteralis Cock- erell known to me only by the figure and description by Gillette and Palmer. From this species piutapa differs, in size, the less acuate cauda with fewer lateral hair, a larger number of secondary sensoria, shorter rostrum, and the second work of the media much eloser to the margin of the wing. The host plants of the two species also differ. Holotype alate viviparous female. Morphotype apterous viviparous female. Deposited in United States National Museum. MHolotype and morphotype mounted on one slide and representing so far as known all material. Host Lycium parviflorwm. Collected at Tucson, Arizona, April 23, 1935, by R. B. Streets. Aphis wahena new species Apterous viviparous female. Size and general color.—Length from vertex to tip of anal plate vary- ing from 1.7-1.47mm. Color notes not available, but the species was referred to as being black. Color of head thorax and abdomen of mouwnt- ed specimens similar and very dark in life most likely black as de- scribed. Entire antennae, legs, cornicles and all of cauda except the median dorsal portion anterior to constriction which is pale, black. Head and thorax.—Comparative length of antennal segments as fol- lows: III .3814-.328mm., IV .185-.214mm., V .143-.171mm., VI .07-1 ++ .171-.30mm. Secondary sensoria distributed as follows: III 3-5 most common number 3, IV 6-10 as a rule 7 or more, V 1-4 as a rule 2 or 38. The secondary senoria are small, have wide rims and are only slightly tuberculate. On III the sensoria are arranged in a row on the apical third of segment, on IV they are arranged in a row with the exception of two or three, on this segment they extend from end to end of the seg- ment. On IV it is common for two or three sensoria to be grouped very close together. On V when the sensoria number more than one they are far apart and arranged in a row. All antennal segments are coarsely imbricated. Antennal hair minute and very sparce. The ros- trum extends to just beyond the metathoracic coxae. Segments IV and ._ V of the rostrum are slightly longer than the hind tarsi, segment four is rather thin but not needle-like. The anterior margin of the head is rather broad and slightly convex it carries several very minute hair. The prothorax is provided with a pair of lateral tubercles. The hind tibiae measure about .786mm. in length. The hair on the outer margin Hottes-Wehrle—Arizona Aphididae 51 of the hind tibiae is very sparce and equally distant throughout the length of the tibiae, with the exception of the hair at the apex it is about one half the width of the tibiae in length. The hair on this margin is much inclined. The hair on the inner margin of the tibiae is less in- clined, longer and about two times as abundant as that on the outer margin. The hind tarsi are .Jmm. long. Abdomen.—The first segment of the abdomen is provided with a pair of small lateral tubercles, a similar pair is located posterior to the cornicles. The surface of the abdomen is very finely imbricated, the imbrications being very close together. Abdominal hair very sparce, minute and very fine, similar to that on antennae. The cornicles vary in length from .347-371mm. being exceptionally long for an Aphis. The cornicles are very coarsely imbricated throughout, a rim is present at the apex but this is not well developed. The cornicles show a tendency to bend outwardly and with the exception of a wide area at the base have a fairly uniform width. The cauda is .143mm. long, its surface is coarsely setulose. The cauda is constricted near the middle, and most specimens show a secondary constriction near the apex, each side is pro- vided with two strongly incurved hair. Alate viviparous female. Size and general color.—Length about .929mm. Data on color not available but apparently similar to apterous viviparous female in all re- spects, however some mounted specimens appear lighter in color than others. Head and thorax.—Comparative length of antennal segments as fol- lows: TIT .314-.371mm., IV .185-.214mm., V .157-.185mm., VI .071 + 14mm. Secondary sensoria distributed as follows: III 12-15 irregu- larly arranged but confined more or less to one side cf segment, IV 6-9 irregularly arranged but confined largely to one side. V 3-4 irregularly spaced, but more or less in a row. All sensoria comparatively large, with wide rims, only slightly tuberculate. All antennal segments coarsely im- bricated. Antennal hair minute, and sparce. Rostrum extending slightly beyond the coxae of the metathoracic pair of legs, fourth segment almost two times length of base of VI. Anterior margin of head convex with a median tubercle, provided with minute hair. Prothorax with a pair of smali lateral tubercles. Hind tibiae .929mm. long with hair similar to that of apterous viviparous female. Stigma pale dusky with a scale- like surface, rather narrow. Radial sector little bowed. Second branch of media much closer to margin of wing than to first branch. No veins reach the margin of the wing. Veins pale lightly bordered with dusky. Abdomen.-—First abdominal segment and segment posterior to corni- eles provided with a pair of small lateral tubercles. Cornicles .30mm. long otherwise as in the apterous viviparous female. Cauda as in apter- ous viviparous female. 11-14mm. long. The cornicles of this species are almost exact duplicates of the corni- eles of Aphis illinoisensis Shimer. The antennae except for sensoria and relative lengths of segments are also suggestive of illinoisensis, however the cauda differs from that species not only in shape but in number of 52 Proceedings of the Biological Society of Washington hair. From Aphis nyctalis H&F it can be quickly separated by the eauda hair, and much longer cornicles. The type slide of this species has been deposited in the United States National Museum, it contains both alate and apterous viviparous fe- males. Data associated with this species. Collected by L. P.

BAKER AND Bryan P. GLass University of Kansas and Oklahoma Agricultural and Mechanical College The two pocket gophers, Geomys bursarius and Geomys breviceps, are currently classified as two full species. The history of the taxonomic work that has resulted in the present arrangement of these two alleged species (and their respec- tive subspecies) can be followed by consulting: 1. Davis (Texas Agric. Exp. Sta., Bull. 590:1-38, October 23, 1940), 2. earlier literature cited by Davis (op. cit.), 3. Villa and Hall (Univ. Kans. Publ., Mus. Nat. Hist., 1:217-236, November 29, 1947), and 4. Baker (Jour. Mamm., 31:348-349, August 21, 1950). The two kinds, G. bursarius and G. breviceps, have not been reported as taken -at the same place and their ranges were not known to overlap. In the University of Kansas Museum of Natural History there were, from Oklahoma, specimens of Geomys breviceps dutcherit from Tecum- seh, Pottawatomie County, and specimens of Geomys bursarius major from Norman, Cleveland County, only thirty miles to the westward. To learn whether these two pocket gophers came together and whether intergradation occurs between them, a field party from the University of Kansas Museum of Natural History,* in November, 1949, collected at ten stations fairly evenly spaced between the two places mentioned above. Geomys was taken at all ten stations (31 specimens in all) and was found to have a continuous distribution in the area concerned. Study of the specimens shows that intergradation occurs between the two alleged species. Additional collecting by one of us (Glass) dis- closes that these two alleged species of Geomys meet along a broad front extending from within Pawnee County on the north into McClain Country on the south. Glass intends to show, in a later paper, the dis- tribution of these pocket gophers in detail. According to Davis (op. cit.) the two alleged species differ in two characters: In Geomys bursarius (=lutescens in Davis) the hind foot is more, instead of less, than 30 mm. long, and the length of the dorso- lateral exposure of the jugal is more, instead of less, than the width of the rostrum measured ventral to the infraorbital openings. In specimens taken between Norman and Tecumseh the hind foot varies in length from 27 to 32 mm. In some of these specimens the length of the jugal is more than the width of the rostrum measured ventral to the *Assistance with field work is acknowledged from the Kansas University Endow- ment Association. 7j—Proc.

In addition to the two differences mentioned by Davis, Geomys bursarius major has larger nasals, rostrum and auditory bullae than G. breviceps dutcheri. Specimens from the thirty-mile transect show intergradation in each of these features. From the evidence given above we conclude that Geomys breviceps and Geomys bursarius are conspecific; the older specific name, bursarius, will apply. Specimens from Oklahoma studied are all in the University of Kansas Museum of Natural History.

Howpen! and RomMEo MANSUETI A survey of the fish fauna of the tributaries of the Ana- eostia River system in Maryland was carried out during the fall of 1948 and continued through the summer of 1949. The investigation of the eight major tributaries was begun to determine the fish fauna since the work of Smith and Bean (1899). Truitt, Bean, and Fowler (1929) record many spe- cies from Prince Georges and Montgomery Counties, but they specify no particular streams. We would like to express our sincere appreciation to Dr. Robert A. Littleford, of the Department of Zoology, Univer- sity of Maryland, for suggesting the problem, guiding us, and providing facilities and equipment. Thanks especially must be extended to Dr. Edward C. Raney, of Cornell University, and to Dr. Ernest A. Lachner, of the United States National Museum, for aid in checking fish identifications. Mr. Byrd Dozier was an able field assistant. The Anacostia River Drainage System covers parts of Prince Georges and Montgomery Counties, Maryland, and comprises an area of about 93 square miles. The tributaries flow in a general north to south direc- tion, bounded on the north and east by the Patuxent River Drainage, and on the west by the Rock Creek Drainage. The Anacostia ultimately flows into the Potomac River near the southern boundary of Washington, Dec, Twenty-five stations were established along the tributaries and each - was visited at least three times. Six of these stations were situated above the Fall Line. For the most part the streams in the Coastal Plain were sluggish, averaging twenty feet in width and one to two feet in depth, with a rate of flow of about two feet per second. Except for the head- water stations, there was a noticeable amount of silt in all of the streams. In the vicinity of the more heavily populated areas, such as College Park, and Hyattsville, sewage was plainly evident. Collections of fish were made by seiming with 25 foot and 15 foot, %4 inch mesh seines. The fish were deposited in formalin in the field and later sorted in the laboratory for identification. 1The work was accomplished by the Senior author in partial fullfillment for a Master of Science Degree at the Department of Zoology, University of Maryland. 15—Proc. Biot. Soc. WASH., Vou. 64, 1951 (93) uhh kd df 1964 eee 94 Proceedings of the Biological Society of Washington At each station physical data, such as width, depth, rate of flow, gradient, air and water temperature were taken. The water tempera- ture did not fluctuate more than 7° F. from the air temperature at any time, and did not become sufficiently cold to warrant the inclusion of cold-water, fish, such as trout. Chemical data included: hydrogen ion concentration, conductivity, and amount of dissolved oxygen in the water. The pH varied from 6.3 to 7.2, while the oxygen varied from 2 ce to 7.3 ec per liter. None of the chemi- cal or physical factors studied seemed to exclude completely or aid in the distribution of the population of fishes. The following specimens were recorded and deposited in the collec- tion of the Department of Zoology of the University of Maryland. 1. Entosphenus lamottenii (LeSueur).—American Brook Lamprey. Specimens were collected on sandy-bottomed streams at ee widely separated stations. 2. Pomolobus pseudoharengus (Wilson).—Alewife. One dead specimen was recovered at Riverdale, March 29, 1949. Reports of many more specimens being fished were gathered at College Park. 3. Catostomus commersonnii commersonnii (Lacepede).—Common White Sucker. This species was collected at almost every station in various stages of growth or size. 4, Hypentelium nigricans (LeSueur).—Hog Sucker. A number. of ju- veniles were collected during the summer in the headwaters of various tributaries. 5. Erimyzon oblongus oblongus (Mitchill).—Eastern Creek Chubsucker. A single specimen was taken in the muddy backwater of Indian Creek. 6. Cyprinus carpio Linneaus—Carp. Carp were particularly common in the muddy backwaters of Northeast and Paint Branch. 7. Semotilus corporalis (Mitchill)—Fallfish. This species was widely distributed at almost half of the stations, the majority of the spec- imens taken being juvenile. 8 Semotilus atromaculatus atromaculatus (Mitchill).—Northern Creek Chub. Relatively common in the clear upper waters of several of the tributaries. 9. Rhinichthys atratulus atratulus (Hermann).—Eastern Blacknose Dace. The dace were numerous at almost all of the stations in mod- erately moving currents. 10. Exoglossum mazillingua (LeSueur).—Cutlips. Commonly distributed in the tributaries of Northeast Branch. 11. Clinostomus vandoisulus (Cuvier and Valenciennes). Red-sided Dace. Present in headwaters of the various tributaries in large numbers, especially in deep pools in winter. 12. Notemigonus crysoleucas crysoleucas (Mitchill).—Eastern Golden Shiner. Present mainly in lower sluggish tributaries, where they were extremely abundant. 13. Notropis rubellus (Agassiz).—Rosyface Shiner. This species was present mainly in the lower reaches of Northwest Branch. 14. 27. 28. 29, 30. 31. 32.

SMiTrH** A fine series of reptiles secured by Mr. Thomas MacDougall in 1949 on the Pacific slopes of the Isthmus of Tehuantepec, Oaxaca, Mexico, contains a single specimen of an undescribed and unnamed species of Tantilla which may be known as: Tantilla triseriata new species Holotype. Univ. Ill. Mus. Nat. Hist., No. 20198, a female from Coatlan, Oaxaca, collected October 9, 1949, by Thomas MacDougall. Diagnosis. A three-lined, light-collared Tantilla with 163 ventrals, 61 subcaudals, prefrontals twice as long as internasals, and relatively extensive markings on lower jaw (including a pair of comma-shaped brown marks on the third and fourth infralabials).

Seales in 15-15-15 rows, smooth, unpitted; ventrals 163, anal divided, subeaudals 61. Total length 203 mm., tail 45 mm.; sex female. Top of head anterior to nuchal collar chestnut brown except for a Narrow semicircular light mark bordering sutures of rostral with nasal and internasal; side of head anterior to eye brown with a distinct yellow triangular mark occupying posterior portion of nasal, first, second, and a portion of third supralabials; behind eye a large yellow spot occupying posterior half of anterior temporal, lower postocular, and most of fourth and fifth supralabials; ventral side of head light yellow and with a num- ber of dark marks, including as the most prominent a comma-shaped area continuous with vertical dark band through eye involving third and fourth infralabials and extreme edge of posterior chinshields; anterior half of mental, nearly half of first infralabials, and posterolateral corner of second infralabial dark. Nuchal collar two scale lengths wide dorsally, 2% scale lengths wide laterally; posterior border a maximum of a full scale length behind rear edge of parietal, anterior border a scale length cephalad from rear edge of parietals and passing ventrally through the secondary temporals and posterior third of seventh supralabials. Ground color of body rich chestnut brown dorsally with three light yellow longitudinal stripes; middorsal stripe beginning 1% scale lengths behind nuchal collar, at which point it is one scale wide; seven scale lengths behind collar middorsal stripe widens, covering inner halves of paravertebral scale rows, continuing almost to tip of tail; lateral stripes beginning three scale lengths behind seventh supralabials, 1% scale lengths behind nuchal collar, occupying adjacent halves of third and fourth scale rows, continuing almost to tip of tail; light stripes on body approximately half the width of dark background; middorsal stripe, ex-. cept at extreme anterior end, slightly wider than laterals; venter light yellow and unmarked; lowermost scale row of same color as venter an- teriorly, ground color extending onto upper edge progressively more extensively toward anus, beginning at about level of 12th ventral and involving a maximum of 1/2 the scale row in front of anus. Comparisons. Of the species now known from Mexico, the ones most closely resembling T. triseriata are T. jani, T. striata, and T. flavilineata. From Tf. striata the new species differs in having higher ventral and sub- caudal counts and in details of pattern. From T. striata and T. flavili- neata it differs in having a higher subcaudal count and a sharp contrast between ground color and the color of the collar and longitudinal light stripes. Actually, however, T. triseriata appears to belong to a Central ’ American group, not previously recorded from Mexico. Unquestionably Tf. taeniata of Guatemala is its closest relative, from which it differs by at least those features already pointed out in our diagnosis. The original description (Bocourt, Miss. Sci. Mex, Amer. Cent., Rept., livr. 9, 1883, p. 587) indicates a greater similarity than does comparison of our speci- men with Bocourt’s figure (op. cit., livr. 10, 1886, pl. 37, figs. 3, 3a-d) H. M. and P. W. Snuith—A New Snake 99 inasmuch as the most obvious differences between the species are found in the nature of the head markings and arrangement of head scales. Differences other than those here emphasized but evident upon compari- son of Bocourt’s illustration and our type may prove constant despite variability in other species. The remarkably large size of the prefrontals in both species is perhaps a unique group character. Inasmuch as the type is slightly desiccated we have not attempted to examine teeth. Coatlan is iocated in central southern Oaxaca, west of the narrowest portion of the Isthmus of Tehuantepec. Extent of range of the species is not evident, but it would not be expected to approach that of T. taeniata, the closest known relative.

Variation. The paratypes exhibit the following variation. The number of femoral pores in 36 specimens varies from 7 to 11, average 8.2 (7-8, four; 8-8, twelve; 8-9, nine; 9-9, five; 9-10, one; 10-11, one; 11-11, two). The number of dorsal scales varies from 27 to 33, average 28.5. (27, thir- teen; 28, eight; 29, eight; 30, three; 32, three, 33, one). The number of supraoculars is available for 35 specimens as follows: 4-4, two; 4-5, three; 5-5, twenty-nine; 5-6, one. The condition of the prefrontals in 25 specimens is also variable; the scales are in contact medially in 22 specimens, separated by an azygous scale in three. The number of ventral seales between the anus and anterior border of the shoulders in 15 specimens varies from 36 to 47, average 40.2 (36, one; 37, one; 40, two; 42, three; 43, two; 44, two; 45, two; 46, one; 47, one). Distinctness of dorsal pattern varies from an almost black ground color with indistinct dorsolateral light stripes to a gray green ground color with more or less distinct light greenish dorsolateral stripes, slight- ly less than two scales in width. The latter condition is found chiefly in the females. Some females and sub-adults of both sexes usually have six P. W. and Z. M. Smith—A New Inzard 103 to seven transverse black bands, about a scale length in width, which are interrupted middorsally and dorsolaterally by the longitudinal light stripes. Chins of females and juvenile males are uniform gray green or gray with longitudinal dark stripes. Venters of females are immaculate or irregularly marked with dark lines or dots, usually with a midventral dark line. Adult males have blue black chins, blue belly patches, a heavy midventral dark stripe, and the entire venter is suffused with black. Comparisons. The adjacent race of S. spinosus is S. s. caeruleopunc- tatus, which inhabits the area immediately to the north of that occupied by S. s. apicalis and differs most markedly in possessing more numerous dorsals (28 to 37, 91% with 31 or more), and more numerous femoral pores (8 to 14, 87% with 10 or more); a difference in pattern may well exist, for the new form shows no evidence of the two rows of dark blue spots between the dorsolateral light lines as is so characteristic of S. s. caeruleopunctatus. Actually the race most closely duplicating the new form is S. s. spino- sus, in spite of the separation of the ranges of the two forms by that of S. s. caeruleopunctatus. The only features we have observed to differ between S. s. apicalis and S. s. spinosus is number of supraoculars (4 in 78% of S. s. spinosus, 7% of S. s. apicalis; and contact (88% of S. s. apicalis) or separation (88% of S. s. spinosus) of the prefrontal scales. The latter character is highly variable in S. s. caeruleopunctatus. Remarks. Intergradation between S. s. caeruleopunctatus and S. s. apicalis probably occurs between Ejutla and Miahuatlan. Specimens from a short distance to the north of Ejutla (mear Ocotlan) are ap- parently typical of the more northern race, whereas those from an ap- proximately equal distance to the south near Miahuatlan are of course S. s. apicalis. Incomplete data on two specimens in the American Mu- geum (nos. 18598-9) from ‘‘Miahuatlan to Ejutla’’ are, however, more or less typical for the more northern race (dorsals 33, 32; supraoculars 5-5 in each; femoral pores 10-11, 12-12); the specimens presumably were taken nearer the biotic area including Hjutla than that encom- passing Miahuatlan. At least one character is unique for each of the three races of S. spinosus. In virtually all respects the central race, S. s. caeruleopunc- tatus, is more primitive than the two peripheral forms, which may well be regarded as somewhat parallel derivatives of a common ancestor similar to the present central race. No difference in habits or habitat between the three races of S. spino- Sus are now apparent. Field notes record that Burger’s specimens were taken ‘‘in brush’’ and on ‘‘open rocky hillsides.’’ The zoogeography of southern Oaxaca is obviously inadequately known. The race here described is apparently restricted to the ranges of moun- tains south of the Tehuantepec River and east of the Rio Verde. A growing body of evidence points toward the existence in this region of a degree of endemism, at least at high elevations, that merits zoo- geographic recognition. 104 Proceedings of the Biological Society of Washington Vol. 64, pp. 105-108 August 24, 1951 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON TWO NEW MAMMALS FROM CENTRAL MEXICO By WAutTER W. DALQUEST Louisiana State University Musewm of Zoology, Baton Rouge, La. : While working on a synopsis of the North American bats of the genus Pipistrellus (Hall and Dalquest, Univ. Kansas Publ. Mus. Nat. Hist., vol. 1, no. 26, 1950), I was impressed by the paucity of Canyon Bats, Pipistrellus hesperus, from the pla- teau of central Mexico. Indeed, there seems to be but a single record of this species from central Mexico, and this locality, in Jalisco, is several hundred miles south of the remainder of the known range of the species. Consequently, when I found Canyon Bats in the state of San Luis Potosi in the summer and fall of 1950, a fairly large series was collected. I expected that these specimens would be referable to Pipistrellus hesperus australis Miller, described from Barranea Ibarra, Jalisco, in 1897, on the basis of four specimens in alcohol. Comparison with three of these four specimens of australis shows, however, that the bats from San Luis Potosi are distinct. According to Miller (N. Amer. Fauna 13, p. 90, 1897), the forearm of the type of australis measured 29 milli- meters. In the three topotypes examined by me, the forearms measured 28.3, 28.5, and 29.3 millimeters. The smallest Pipistrellus from San Luis Potosi has a forearm 29.6 millimeters in length, and in other features also, the specimens from San Luis Potosi are all larger than the bats from Jalisco. The color of Pipistrellus hesperus australis is not known, but Miller (loc. cit.) judged, from the comparison of the topotypes with other alcoholic specimens, that australis is darker than Pipistrellus hesperus hesperus (Allen). Hatfield (Journ. Mamm., vol. 17, p. 260, 1936), thought that Canyon Bats from Sonora and Lower California belonged to the same race as the bats from Jalisco, and these he described as ‘*Dorsally between cinnamon drab and drab...’’ The Canyon Bats from San Luis Potosi are darker than this. The Canyon Bats from San Luis Potosi seem to belong to an unnamed race, and may be known as: Pipistrellus hesperus potosinus new subspecies Type.—Adult male, skin and skull number 4019, Louisiana State Uni- versity Museum of Zoology; obtained at Presa de Guadalupe, San Luis Potosi, México, by Walter W. Dalquest on July 24, 1950; original number 14318. Range.—Known only from the western and central parts of the state 18—PRoo. BioL. Soc. WASH, Vou. 64, 1951 (105) 7 xe S$ +5 £EP 106 Proceedings of the Biological Society of Washington of San Luis Potosi, México, but probably ranging over the eastern part of the Mexican Plateau. Diagnosis.—Size large for a Canyon Bat, only slightly smaller than the largest known races of the species; color dark, varying from Drab to Sepia (Ridgway, Color Standards and Color Nomenclature, Wash- ington, D. C., 1912) and averaging darker than the darkest known races of the species. Comparison.—Pipistrellus hesperus neko is larger and darker than Pipistrellus h. australis and all described races of Pipistrellus hesperus save P. h. maximus and P. h. santarosae. From these latter two races, potosinus may be distinguished by its much darker color. A single in- dividual potosinus is much paler than the rest of the series, and this specimen is as dark as the darkest santarosae and darker than the darkest maximus examined. Measurements.—The arithmetic means, with extremes in parentheses, for 12 males and 10 females, are, respectively: total length, 74 (71-77); 80 (77-85); length of tail, 31 (30-33), 33 (32-35); length of foot, 6 (5-6), 5 (5-5); height of ear from notch, 13 (13-14), 14 (13-14); height of tragus, 5 (5-5), 5 (5-5); length of forearm, 30.8 (29.6-31.8), 32.3 (30.5-33.5) ; greatest length of skull, 12.7 (11.7-12.8), 12.9 (12.3-13.6) ; condylobasal length, 12.2 (11.7-12.8), 12.3 (12.0-12.9); zygomatic breadth, 7.8 (7.5-8.2), 8.0 (7.9-8.4); braincase breadth, 6.5 (6.2-6.7), 6.5 (6.1-6.8). Specimens examined.—Total number 27, all from San Luis Potosi, México, as follows: City of San Luis Potosi, 6; San Luis Potosi Reser- voir, 6; Presa de Guadalupe, 12; Hacienda Capulin, 3. | When Howell (N. Amer. Fauna 56, 1938) revised the ground squirrels of North America, he had no specimens of Citellus spilosoma from the central and eastern parts of the state of San Luis Potosi. Recently col- lected specimens show that this area is inhabited by a well-marked but unnamed race, which intergrades with the richly colored Citellus spilo- soma spilosoma (Bennett) on the west and with the pale C. s. pallescens Hewell on the north. The new race is named in honor of Mr. Ernesto Carbrera Ipina of the city of San Luis Potosi, and may be known as: Citellus spilosoma cabrerai new subspecies Type.—Adult female, skin and skull number 4131, Louisiana State University Museum of Zoology; obtained at 10 kilometers north-north- east of Nufiez, San Luis Potosi, México by Walter W. Dalquest on July 5, 1950; original number 14102. Kange.—Desert areas of central and eastern San Luis Potosi and prob- ably adjacent parts of the states of Guanajuato and Tamaulipas, México. Comparisons.—Citellus spilosoma cabrerai is slightly smaller than Citellus s. spilosoma, has a smaller, narrower skull, and is much darker and less reddish in color. Compared with C. s. pallescens, cabrerai is similar in size and cranial features, but is darker and duller, less brown, in color. The spots on the dorsal area of C. s. cabrerai are more ob- scure than those of either of the two neighboring races. Measurements.—The measurements of an adult male and the arith- metic means for the measurements of two adult females are, respec- Dalquest—Two New Mammals 107 tively: total length, 249, 245; length of tail 80, 78; length of hind foot, 34, 34; height of ear from notch, 9, 10; greatest length of skull, 40.5, 40.6; condylobasal length, 35.9, 36.3; palatilar length, 18.0, 18.4; zygo- matic breadth, 23.0, 23.8; cranial breadth, 19.0, 19.2; interorbital breadth, 9.1, 9.0; post-orbital constriction, 14.0, 14.6; length of maxillary tooth row, 7.1, 7.9. Remarks.—The greater part of the desert of the state of San Luis Potosi is occupied by this race of Citellus spilosoma. Citellus spilosoma spilosoma occurs in western San Luis Potosi, west of the city of San Luis Potosi. Intergradation takes place at Arriaga, Tepetate, the city of San Luis Potosi, and at Hacienda la Parada. Specimens from the latter two localities were referred by Howell (loc. cit., p. 125) to Citellus s. pallescens. The geographic range of C. s. pallescens lies mainly to the north of the state of San Luis Potosi, and only specimens from the extreme northern tip of the state are referable to pallescens. Specimens examined.—Total number 6, all from San Luis Potosi, México, as follows: Esperanza, 1; 10 km. NNE Nufiez, 1; 6 km, SSW Nuiiez, 1; 6 km. S. Matehuala, 2. I am indebted to Hartley H. T.

JOHNSON U. S. National Museum The American water shrews of the species Sorex palustris are rare in collections of mammals from the Labrador Penin- sula, which includes Labrador proper and the part of Quebec that lies between Hudson Bay and the Gulf of St. Lawrence. Including those newly recorded here, I know of 10 specimens from seven different localities in this entire area of about 175,000 square miles. They are scattered in four collections, and the six specimens that have received previous notice have been variously assigned to the subspecies albibarbis, glover- alleni, and labradorensis. Specimens in the collection of the Carnegie Museum, Pittsburgh, have been loaned for study through the courtesy of J. Kenneth Doutt, and C. F. Jackson of the University of New Hampshire has similarly loaned specimens from his collection. All previously published records from the Labrador Peninsula repre- sent localities along the northern shore of the Gulf of St. Lawrence. It now appears that the species is distributed over the entire peninsula, except possibly the most barren part of northern Ungava. The Labrador area has been less studied by mammalogists than other parts of North America, but it is still remarkable that so few water shrews have been collected. Fort Chimo is perhaps the best known collecting locality in the area; numerous specimens of mammals were taken there nearly seventy years ago by L. M. Turner and at later dates by other collectors, but it was not until 1947 that water shrews were caught. There is little available information concerning the natural history and preferred habitat of the shrews. The two Fort Chimo specimens were eaught, along with numerous Sorex cinereus cinereus and Microtus penn- sylvanicus labradorius, in the small area of meadow-like grassland that surrounds the Hudson’s Bay Company post buildings. This locality is approximately at the northern limit of tree growth, where small patches of stunted spruce and larch trees are surrounded by tundra and muskeg, Cartwright and Red Bay are in the treeless strip of country bordering the Labrador coast, and the remaining localities are in or bordering spruce-forest areas. There is no apparent altitudinal restriction; most of the specimens were taken near sea level, and the one from Astray Lake was on the height-of-land on the main divide of the peninsula. Labels of three of the specimens_bear the following collector’s notations: / Saas by permission: Of ‘the cere Qt the Smithsonian Insti- ution 19—Proo. Bron.

Doane at Cartwright); ‘‘Run in sphagnum and reindeer moss in spruce thicket. Bottom of gully’’ (H. W. Jackson at Point St. Charles) ; ‘‘Damp gully in cliff, very wet and cold’? (H. W. Jackson at Seal River). These shrews are apparently less restricted to a streamside habitat than is Sorex palustris navigator in the relatively arid mountains of western North America. Study of the available specimens indicates that there are three sub- species of Sorex palustris on the Labrador Peninsula, one of which has not been previously described. Sorex palustris turneri, new subspecies Type locality—Fort Chimo (on the eastern bank of the Koksoak River, lat. 58° 8’ N., long. 68° 15’ W.), Ungava district, Quebec, Canada. Type specimen.—U. S. National Museum No. 282879; skin and skull, adult male in summer pelage; collected October 4, 1947, by Maj. Robert Traub and Sgt. Donald Koelle; prepared by D. H. Johnson, original number 5216. Characters——Upperparts in summer pelage Fuscous-Black (this and other capitalized color terms after Ridgway, 1912), darker than in any of the described races of Sorex palustris except possibly brooks: of Van- couver Island; belly Mouse Gray; underparts in general, including underside of tail and inner sides of feet, paler than in labradorensis, albibarbis, and hydrobadistes, darker than in gloveralleni, palustris, and navigator; underparts less suffused with brownish color than in any of the foregoing races except palustris; tail bicolored almost to tip. Winter pelage unknown. Skull small, with relatively weak rostrum and broad braincase. For measurements see Table I. Remarks.—Of all the races of Sorex palustris described gh eastern North America, this one is outstanding for the reduction of the amount of brown pigment visible in the summer pelage. With the unusually dark upperparts, this produces a distinctive black-and-gray appear- ance. The darkened skin on the back of each specimen indicates that molt to winter pelage would take place shortly after October 4, the date on which they were collected. The nearest relative, both geographically and in point of characters, is S. p. labradorensis, and intergradation is presumed to take place with that race. There is, however, a gap of 400 or more miles from which no specimens are available between the nearest localities of the two races. This race was discovered in the course of a survey of small mammals and their ectoparasites occurring about air bases in northeastern North America conducted by the Army Medical Service Graduate School and the Smithsonian Institution in the autumn of 1947. It is named in honor of Lucien McShan Turner, who in 18§2 and 1883, while attached to the U. S. Signal Service, made the first important collection of mammals in the Ungava region, Specimens examined.—Two, from the type locality (U. S. Nat. a Nos. 282879 and 282880, skins and skulls).

Type locality——Red Bay, Strait of Belle Isle, Labrador. Type specimen.—Univ. Michigan Mus. Zool., No. 68109; skin and skull, adult female in winter pelage; collected February 9, 1933, by E. Doane (Burt, 1938). Characters.—Color in summer pelage (based on specimens from Astray Lake and Cartwright): Upperparts between Fuscous and Fuscous-Black, with a scattering of brownish hair tips; underparts near Hair Brown, slightly paler on throat; pale area on underside of tail indistinct beyond proximal third. In winter pelage (as described by Burt, 1938, p. 2): ‘‘Upperparts fuscous black, underparts silver gray. . . Tail bicolor, black above with whitish ventral stripe extending about three-fourths dis- tance to tip.’’ For measurements, see Table I. Remarks.—Burt considered labradorensis a small race because the skull of the type has a condylobasal length of only 19.7 mm., but a specimen of the same sex from nearby Cartwright is larger, with a condylobasal length of 20.4 mm. Records of occurrence.—Three localities are represented: Cartwright, Labrador (on the coast south of Hamilton Inlet, lat. 53° 48’ N., long. 56° 59’ W.). One specimen examined (Carnegie Mus. No. 17981, skin and skull). Red Bay, Labrador (on the Strait of Belle Isle, lat. 51° 45’ N., long. 56° 24’ W.). Type specimen of labradorensis, recorded by Burt (1938, p. 1). Astray Lake, Quebee (‘‘on the height of land between Ste. Margaret River and Swampy Bay River,’’ approximate lat. 53° N., long. 67° W.). One specimen examined (Carnegie Mus. No. 4103, skin only).

Sorex palustris gloverallent H. H. T. Jackson, Jour. Mammalogy, vol. 7, p. 57. February 15, 1926. (Renaming of acadicus Allen.) Type locality—Digby, Nova Scotia. Type specimen.—Bangs Collection, Museum of Comparative Zoology, No. 2046; skin and skull, adult female; collected July 26, 1894, by Outram Bangs. Characters.—Color in summer pelage (based on specimens from Point St. Charles and Seal River): Upperparts near Fuscous-Black; under- parts Light Drab; pale area on underside of tail extending completely to tip. Skull about as in albibarbis and labradorensis, smaller than in palustris, Remarks.—In the pale underparts and the well marked light streak extending to the tip on the underside of the tail, the specimens from the northern shore of the Gulf of St. Lawrence resemble both palustris and gloveralleni and are sharply distinct from the other, darker-bellied, eastern races. In their small size (see Table I for measurements) they resemble gloveralleni rather than palustris. The three specimens from Godbout have been in alcohol for many years and as a result their colors 112 Proceedings of the Biological Society of W ashington are badly faded. One of these is in winter pelage and has very pale underparts; the other two are in summer pelage and have far more con- trast in color between the dorsal and ventral color areas than exists in skins of albibarbis. They were considered intermediate between glover- alleni and albibarbis and tentatively referred to the latter race by H. H. T. Jackson (1928, p. 182). The Seal River and Point St. Charles speci- mens were correctly identified as gloverallenit by C. F. Jackson (1938, pp. 431-432), and, with the presence of this race definitely established north of the St. Lawrence, the specimens from Godbout are best in- cluded under it. Records of occurence——The following five specimens have been ex- amined from the Labrador Peninsula: Point St. Charles and Seal River, Quebee (vicinity of Moisie River on the Gulf of St. Lawrence, approximate lat. 50° 20’ N., long. 66° W.). Two specimens (C. F. Jackson Coll. Nos. 373 and 374, skins and skulls); previously recorded by C. F. Jackson (1938, p. 342). Godbout, Quebec (on the Gulf of St. Lawrence, lat. 49° 19’ N., long. 67° 37’ W.). Three specimens examined (U. S. Nat. Mus. Nos. 74651, 99185, and 178503, all alcoholics with skulls removed and cleaned); previously recorded by H. H. T. Jackson (1928, p. 183) as S. p. albibarbis. LITERATURE CITED Burt, William Henry 1938.

CAUSEY Fayetteville, Arkansas The millipeds of Suborder Chordeumoidea are of particular interest because of the many modifications of the ninth legs of the males. These legs, which are referred to as posterior gonopods by European writers, vary from the normal seven segments down to seemingly functionless stubs coalesced with the sternite of the seventh segment. The body length may be as little as 2 or 3 mm; the number of postcephalic segments may be 20, 26, 28, 30, or 32; and the color may vary from white to dark brown. Except for the excellent monograph by Cook and Collins (1895), the the only published works on chordeumoid millipeds in the United States are a few short papers and descriptions of a few species in papers deal- ing chiefly with other groups of Diplopoda. The families, in general, remain poorly defined. The specimens described in this paper came either from the author’s private collection or from the collection of the Illinois Natural History Survey. Holotypes of Trigenotyla parca, Ofcookogona steuartae, and O. _ alia will be deposited in the collection of the Philadelphia Academy of Science. Paratypes of these and the holotype of Flagellopetalum stan- nardi are in the collection of the Illinois Natural History Survey. Unless stated otherwise, collection was by the author.

Trichopetalum lunatum Harger Figs. 6-8 Trichopetalum lunatwm Cook and Collins, 1895, ibid., p. 63, figs. 52-54. Four males and several females collected by L. J. Stannard, Telford, Pa., Oct. 1, 1947, Ace. No. 4943, are believed to be Harger’s poorly de- seribed 7. lunatum. It is regretted that no specimens of 7. album are available for comparison, because the Pennsylvania specimens are very similar-to that species. The two are probably indistinguishable as to body length, color, ocelli, etc. The ninth legs of lunatum (Fig. 6) have no processes on the coxosternal region; if the figure shown by Cook and Collins (1895, fig. 43) is correctly drawn, albwm has prominent triangular processes in that region. The telopodites of the gonopods are contiguous only at the base and at the distal end. They extend to the base of the eleventh legs. Laterad the basal two-thirds of the telopodite is finely pubescent; mesiad about midway of its length are three stout setae; on its mesial surface is a thin, triangular lobe, visible in situ and not shown in the figure for album; the end is flattened (Fig. 7) and hamate. Springing from near the base of the telopodite, mesiad, is a single plu- mule; there are two of these in album. The dorsal lamella, with two tri- angular pieces on the posterior margin, appears in albwm to have only one triangular piece. F Flagellopetalum, new genus Resembles Trichopetalum in the small size of the body, in having 28 segments behind the head, in the presence of keels on most body seg- ments, the conspicuous needle-like segmental setae, the slightly clavate antennae, the triangular promentum, the presence of short, stiff setae on the mesial surface of the tarsi of the first and second legs, in the smaller size and absence of a segment in those legs, and in that the ninth legs of the male consist of only two segments, the basal of which has no lamella or processes. It differs from Trichopetalum in that the ocelli are fewer and in one row, the sixth legs of the male have a lobe on the 120 Proceedings of the Biological Society of Washington fourth segment, the second segment of the ninth legs is less swollen and has no terminal, chitinized knob, and the gonopods have no plumose piece. The gonopods consist of three pairs of lamellae, of which the dorsal pair is coalesced at the base and terminates in a pair of fine, flagelloid processes. Genotype.—Flagellopetalum stannardi, n. sp. Flagellopetalum stannardi, n. sp. Figs. 9-12 Male holotype.—White with light gray bands across the prozonites and metazonites. Eyes composed of five ocelli arranged in a single curved line on a darkly pigmented horizontal band. Keels of middle body region as shown in figure 9, decreasing in size posteriorly, the last three - segments without keels. Segmental setae needle-like, relatively long. Surface of tergites appear lightly longitudinally striate when viewed under high magnification. As shown in figure 10, the fourth segment of the sixth leg bears a small lobe on the mesial surface. No other anterior legs are modified except the first and second, as explained in the definition of the genus. The tenth and eleventh legs have the usual coxal openings. The ninth legs are shown in figure 11; they are not inflated and the coxoprefemur, which is disinct from the sternite, bears no processes. The gonopods (Figs. 11, 12) consist of three pairs of lamellae: the dorsal lamellae, probably sternites, are coalesced at the base, but distally they are flagelloid; both surfaces of the middle lamellae are finely hispid, and laterally each bears a curved, aciculate process; the ventral lamellae bear a pair of sharp spines of the ventral surface and acute lobes on the distal margin. Length 4.5 mm. Type locality—Rocky Branch, Clark Co., Ill. The male holotype and a larva were collected Oct. 19, 1947 by L. J. Stannard, for whom it is a pleasure to name this species. Family Cleidogonidae Ofcookogona, new genus Resembles Tiganogona Chamberlin 1928 in the close union between the dorsal branches of the gonopods and the coxal region of the ninth legs and in the presence of a clavate sternal process anterior to the ninth legs. It differs from Tiganogona, in which the ninth legs appear to con- sist of five segments, in that those legs consist of the following three segments: a swollen basal segment with lobes; a medial, smaller, spheri- cal segment; and a terminal, minute segment. The male gonopods, which are heavier than in Tiganogona, consist of well developed cheirites, a single medial piece, and the usual dorsal and ventral branches. The eyes are triangular, the ocelli black and numbering under 20. Antennae long and slender as is usual in the family. Tergites smooth, no keels, color typical of the family. First and second legs reduced in size. Tarsi of legs three through seven, ten and eleven with papillose cushion on mesial surface. Third segment of eleventh legs of males modified; tenth and eleventh legs with the usual gland opening on the coxae. Genotype.—Ofcookogona steuartae, n. sp. Causey—New Genera and Species of Millupeds 121 Ofcookogona steuartae, n. sp. Fig. 13 Male holotype.—Ocelli in rows of 1, 7, 6, 5, 4, 3, 1. On the proximal end of the medio-caudal surface of the eleventh legs is a cylindrical process. The tenth legs are unmodified. The ninth legs are not visible until the pleura are removed; the inflated basal segment has two lobes on the dorsal surface; the spherical second segment and the minute terminal segment are difficult to distinguish from the basal segment. The presence of a terminal claw is doubtful. Slightly anterior to the ninth legs is a clavate sternal peg, which is about two-thirds as long as the two finger-like coxal lobes adjacent to it. In situ, lateral view, the ventral branches of the gonopods appear almost parallel to the longitudinal body axis, reaching to the base of the eleventh legs; in ventral view they appear as two elongated wedges, the apices contiguous and the bases well separated. The distal third of each ventral branch bears along the dorsal surface a thin lamella, its dorsal margin finely serrated. The dorsal branches of the gonopods are falcate rather than clavate, as in many species of this family. The cheirites, the triangular lateral pieces, are well developed. Length 13 mm, width 1.3 mm.

Ofcookogona alia, n. sp. Figs. 14-16 Easily separated from O. stewartae by the absence of a serrated mar- gin on the ventral branch of the gonopods and by difference in the shape of the ninth legs. Male holotype.—Ocelli in rows of 1, 7, 6, 5, 4, 2. Modification of legs as in steuartae. The ninth legs are not as inflated as in stewartae. From the cephalic surface of the coxal region of each one a finger-like lobe passes up to the base of the ventral branch of the gonopod. A smaller lobe is em- braced medially by the dorsal branch of the gonopod. The small, globose, darkly pigmented segment appears to be the second; distal to it, and easily overlooked, is a minute knob, the third segment probably. Slightly anterior to the ninth legs is the sternal peg, not broadly clavate as in steuartae, the surface finely and uniformly roughened and the length about half that of the coxal lobes adjacent to it (Fig. 14). In situ, ventral view, the ventral branches of the gonopods are con- tiguous at the base and separate distally in a V-shape; the apices rest on the ventral surface of the coxae of the tenth legs. In lateral view each gonopod, as in stewartae, is seen to be composed of four pieces (Fig. 15): the ventral, broadly curved piece; the dorso-lateral triangu- lar cheirite with a row of a few stiff setae; the dorsal arcuate piece, spathulate in dorsal view (Fig. 16), which embraces the medial sternal peg of the ninth segment; and the mesial, excavated piece.

Vol. 64, pp. 125-128 November 19, 1951 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON A NEW RACE OF DUSKY GROUSE (DENDRAGAPUS OBSCURUS) FROM THE GREAT BASIN By WILLIAM H. BEHLE AND ROBERT K. SELANDER A systematic review of the subspecies of Dendragapus obscurus was presented by Swarth (Proc. Calif. Acad. Sci. (4), 20, 1981:1-7) when he described the race D. o. pallidus. His material, however, did not reveal the picture of variation in the Great Basin. He commented that conditions were not clear at the southern boundaries of richardsonu and pallidus and in the territory where either or both approach the range of obscurus. Subsequently, Linsdale (Pacific Coast Avifauna No. 23, 1936 :47), in his study of the birds of Nevada, assigned the grouse from the desert mountain ranges of the eentral portion of the state (Toyabe, Toquima and Monitor moun- tains) to pallidus and those from the northeastern and central eastern sections (East Humboldt, Jarbidge, Shell Creek and Snake mountains) to obscurus. During our recent field work in the Deep Creek Mountains of central western Utah, adjacent to the Goshute Indian Reservation just north of the Snake Range of Nevada, several specimens were obtained which, on the basis of the literature, we expected to represent obscurus. Such did not prove to be the case, and a study of the Dusky Grouse of the entire Great Basin and surrounding areas has convinced us that a differ- ent race exists in eastern Nevada and western Utah which we now describe as Dendragapus obscurus oreinus, new subspecies Great Basin Dusky Grouse Type—Adult 8, No. 10779, University of Utah, Museum of Zoology; 3 miles north of Queen of Sheba Mine, 7500 feet, west side Deep Creek Mountains, Juab County, Utah; April 23, 1950; Collected by Robert K. Selander, original number 556; testis 14 mm. Subspecific characters—Compared with obscurus, adult males of oreinus have the ground color of the feathers of the dorsum a lighter brown; they show more white on the edgings of the scapulars, primary and secondary coverts; the vermiculations of the scapulars, sides, flanks and wing coverts are paler and grayer. The latter distinctions are especially noticeable from a lateral view and the mass effect is a paler, grayer bird than obscurus. Females are even more distinct, those of oreinus being paler and possessing tan, buff, and gray colors rather than rich brown. This is most evident on the secapulars, wing coverts, and flanks. Nape and auriculars gray instead of light buff as in obscurus. __..21—Proc. Bion. Soc. WASH., Vou. 64, 1951 (125) RAGAN INST Poe song AN Si (Ty » %* ij ; f Ram ~~ ~~ 6 oF é 7 am en wov a 21>!

Plumage of upper parts generally paler through having a brown rather than fuscous-black ground color, and the vermiculations of the flanks, sides, wing coverts, and scapulars are lighter and thus more conspicuous. Males more easily distinguishable from richardsoniwi than females. Differs from pallidus in much the same way as from richardsonw, the principal distinguishing character being the possession of the tail band and rounded tail. Measurements.—Adult male (12 specimens) ; wing, 224.0-249.0 (236.6) ; tail, 158.5-184.7 (175.2). Adult female (9 specimens) ; wing, 208.5-221.0 (216.2); tail, 133.0-144.5 (139.9). Geographic distribution.—Known from the Deep Creek Mountains in central western Utah, Snake Range in central eastern Nevada, Ruby Mountains of northeastern Nevada and Toyabe Range in central Nevada. Specimens examined.—Utah: Juab County: head of Pass Creek, 8000 feet, 6 miles east Indian Village, Deep Creek Mountains, 2 (June); 3 miles north of Queen of Sheba Mine, 7500 feet, west side Deep Creek Mountains, 2 (April); Queen of Sheba Mine, 9000 feet, west side Deep Creek Mountains, 1 (May).

Elko County: west side Ruby Lake, 6 miles north Elko Coun- ty line, 11 (Nov., Dec.) ; Harrison Pass R. 8., Green Mountain Canyon, Ruby Mountains, 4 (June); Three Lakes, Ruby Mountains, 2 (July); Long Creek, South Fork, Ruby Moutains, 2 (July). Nye County: Toquima Range, 1144 miles southeast Jefferson, 8600 feet, 2 (July). Lander County: Kingston Creek, 9600 feet, 1 (Sept.); South Fork of Big Creek, west side Toyabe Range, 2 (Oct.); Birch Creek, 8000 ft., 1 (June). Remarks.—This Great Basin race apparently is more closely related to the obscurus stock of the Rocky Mountains to the east than to the palli- dus-richarsonii population to the north. The latter population differs from obscurus in a number of distinctive ways. In ground color, obscwrus is brown, less blackish while the northern population features a dark fuscous-black. In tail characters, pallidus and richardson have a truncate shape and no distinct terminal tail band, while obscurus has a well marked tail band and rounded shape. The race oreinus shares the rounded tail and terminal tail bar with obscurus, and though of a paler coloration, it possesses the warm brown ground color of that race. At the same time oreinus shows a different arrangement of characters by combining the tail shape and band of obscwrus with the grayness of the feather edgings of pallidus and richardsonii. Heretofore it has been thought that the extreme in pallor was reached in the race pallidus of south central British Columbia, eastern Washing- ton and northeastern Oregon. Now it appears that the Great Basin population is even paler. Within the race oreinus the palest specimens examined by us are those from the type locality in the Deep Creek Mountains. Significantly, the paleness is manifest in juveniles as well as adults. In the majority of males of this new race the tail band is pure gray and fully as deep as in obscurus. In some specimens of pallidus and Behle and Selander—A New Face of Dusky Grouse 127 richardson a transverse line gives a suggestion of a band but the colora- tion of the tail anterior and posterior to this line is the same. In speci- mens from the Toyabe Mountains to the west in central Nevada the band is less deep and less distinctive, possessing a mottling which is a puzzling feature. This character probably influenced Linsdale to refer these specimens to pallidus. There may, indeed, be intergradation over an extended area between oreinus and pallidus beginning in this area. These Toyabe specimens now seem best placed with oreinus, however. Possible intergration between oreinus and either pallidus or richard- sonui is indicated by a female from Bear Creek, 8000 feet, Jarbidge Mountains, Elko County, Nevada which locality is near the Idaho border. It shows a darker coloration than oreinus and a rather poorly developed tail band. Another female from one mile east of Strawberry Creek Ranger Station, Wasatch Mountains, Franklin County, Idaho is seem- ingly intermediate between richardson and obscurus, closest perhaps to the former, because of its dark coloration and small, poorly defined tail band. Specimens of obscurus from the Wasatch Mountains of Utah are generally somewhat paler than examples of that race from Colorado and New Mexico. A break occurs between oreinus and obscurus west of the Wasatch Mountains, correlated with the desert hiatus. The Great Basin race, however, occupies isolated mountain ranges. It is not certain whether there are significant differences between the Several races in measureable characters. The figures given in Ridgway and Friedmann (Bull. U. S. Nat. Mus., 50, Pt. 10, 1946:82-89) suggest that the males of pallidus and obscurus are of similar size, with those of richardsonu being smaller. The females of richardsonii and pallidus are about the same size with those of obscurus being slightly larger. Our data based on adult birds indicate that the wing and tail lengths of oreinus are slightly longer than in obscurus. Before size differences can be attributed with certainty to these races there needs to be further evaluation of these characters based on much new material and further- more the age differences noted by Swarth (Univ. Calif. Publ. Zool., 30 (4), 1926:78-84), must be taken into account. We are indebted to Kenneth C. Parkes of Cornell University for the ‘loan of several specimens from the Wasatch Mountains collected by J. Dan Webster and to the following persons for access to museum collections under their care: C. Lynn Hayward, Brigham Young Univer- sity; Robert T. Orr, California Academy of Sciences; Alden H.

Vol. 64, pp. 129-130 November 19, 1951 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON ALLOSEBASTES, NEW SUBGENUS FOR SEBASTODES SINENSIS, SCORPAENID FISH OF THE GULF OF CALIFORNIA! By Cart L. HuBBs The species of Sebastodes that Gilbert (Proc. U. 8S. Nat. Mus., vol. 18, 1890, pp. 81-82) described from the Gulf of California as Sebastichthys sinensis is so distinct as to war- rant its separation as the type and sole member of a new subgenus. Allosebastes, new subgenus The most notable character of this subgenus is the reduction of the anal soft-rays to 5—the number characteristic of Scorpaena and of most other tropical genera (Barnhart and Hubbs, Bull. Scripps Inst. Oceanogr. Univ. Calif., vol. 5, 1946, p. 373). As is often true, the value of this character lies in its consistency rather than in the amount of difference. The tropical genera normally with 5 anal soft-rays very seldom deviate from that number and all of the many other species of Sebastodes, with rare individual exceptions, have 6 to 14 anal soft-rays, usually 6, 7, 8, or 9 (Jordan and Evermann, Bull. U. 8S. Nat. Mus., no. 47, pt. 2, 1898, pp. 1765-1835; Matsubara, Trans. Sigenkagaku Ken- kyusko, vol. 1, 19438, p. 97). The other fins have a ray formula that is normal for the genus Sebastodes: dorsal, XIII, 12 (rather low but not uniquely so in number of soft-rays); caudal, 7 + 7 (principal rays); pectoral, i, 9, vii = 17 in each fin; pelvic, I, 5. The pertinence of the species to Sebastodes or to a very closely related segregate is confirmed by such characters as the scaly, only moderately spiny and little distorted head, the posteriorly narrowed, unkeeled and unspined suborbital stay, the complete dentition, and the normal fins. The definite though thick and blunt intromittent — organ of the male is similar to that of the species of Sebastodes, all of Be which, so far as known, bear prolarvae. | a Other more or less extreme though less trenchantly distinct characters of S. sinensis are the smooth, mostly cycloid scales; the unswollen lower pectoral rays; the excessively long anal spines (the second extends well beyond the longest soft-rays, the third almost reaches the tip of the longest soft-ray); the closely clumped subparallel upper 3 preopercular spines (the lower 2 are well separated and divergent); the protuberant posterior end of the mandible, almost resembling a flat spine; and, espe- cially, the very firm, well-exposed suborbital stay (second suborbital), with the bone widened about the unusually large pore, which has a ws somewhat raised and roughened rim.

Biot. Soc. WASH., Vou. 64, 1951 (129) Nov 1 91951 130 Proceedings of the Biological Society of Washington The general distinctiveness of this species, as well as its reduced num- ber of anal rays, is correlated with its restriction to the essentially tropical fauna of the Gulf of California, where it alone represents this speciose genus of the North Pacific (Jordan and Evermann, lI. ¢., 1898, pp. 1765-1835; Matsubara, 1. ¢., vol. 2, 1943, pp. 175-252, under Sebastes). Except for one species or species-complex ranging from Pert to South Africa, the entire genus is otherwise confined to the more temperate and to the boreal waters of the North Pacific (Hubbs, Pac. Sci., vol. 4, 1950, p. 70). The disjunction of populations, both in the Southern Hemisphere and in the Gulf of California, presumably dates from some Pleistocene period of oceanic cooling (Hubbs, Jour. Mar. Res., vol. 7, 1948 (1949), p. 463). There were presumably several such periods of cooling and Sebastodes sinensis has probably been separated from its congenors since middle or early Pleistocene time. It is not wholly clear, however, that Sebastodes (Allosebastes) sinensis represents an offshoot from Sebastodes, with the number of anal rays independently reduced. A thorough revision of the American species, with attention to such anatomical details as Matsubara (1. c., 1943, vols. 1-2) used in his study of the species of the western Pacific, will be re- quired before the phyletic position of S. sinensis can be interperted with confidence. It may represent a group, or stage of evolution, now largely extinct, that is transitional between the temperate and the tropical genera, or vice versa. It may be shown to be so distinct as to warrant full generic separation. In some respects it resembles Helicolenus, from which it differs at least in the unkeeled suborbital stay and in the number of dorsal spines, 13 rather than 12 (a distinction of great signifi- cance in this group, because of the consistency of the difference). From each of the few genera with 13 dorsal spines and 5 anal soft-rays, as well as from all other genera except Sebastodes, as these were distin- guished by Matsubara, S. sinensis differs im several characters of acknowledged generic import. Not having examined the species and not having noted its more dis- tinective features, classifiers of Sebastodes have variously interpreted the relationships of S. sinensis in the large complex of species. Eigenmann and Beeson (Am. Nat., vol. 27, 1893, p. 670) classed it, along with a miscellaneous assortment of other species, in their new genus Pteropodus. Cramer (Proc. Calif. Acad. Sci., ser. 2, vol. 5, p. 600) associated it in his key with zacentrus, elongatus, levis and rubrivinctus, leaving all in Sebastodes without even subgeneric separation. Jordan and Evermann (Rept. U. S. Comm. Fish and Fish., 1895 (1896), p. 431 and Bull. U. S. Nat. Mus., no. 47, pt. 2, 1898, p. 1776), essentially adopting Cramer’s arrangement, combined sinensis with the 4 species just named in their new subgenus Hispanicus. This note is based on a recent examination of the holotype of Sebasti- chthys sinensis (U.S.N.M. No. 43085). Only the holotype and 1 paratype have been collected, both at Albatross Station 3015 in the Gulf of Cali- fornia, at a depth of 145 fathoms, at 29° 19’ 00” N. Lat., 112° 50’ 00” W. Long.

This much named European centaury may be distinguished from the related Centaurium umbellatum Gilib. by the generally loosely branched cymose-paniculate inflorescence, the smaller cauline and the always in- conspicuous basal leaves withering at anthesis, and the generally lower habit of the plant. Some collections studied are transitional between the two species, however, and these individuals have been made the basis of several described microspecies in Europe. The synonomy of these forms was already complicated a century ago when Grisebach pre- pared the account of the family for the Prodromus,* under the name Erythraea ramosissima Pers. Grisebach did refer at that time to its introduction into the Americas. William Darlington reported it as first _ detected in Chester County, Pennsylvania, in July, 1835, but it has not evidently persisted as an aggressively spreading species in our flora.? Muhlenberg noticed the species even earlier under the name Chironia pulchella as a species of the Pennsylvania flora? but the full details of that intricate story must await a search in the historic collections at Philadelphia now in progress.® Outside of the United States early collections of Centauriwm pulchel- lum were made in the West Indies, first in Bermuda at St. George, May 23, 1854, I. F. Holton 469 (K®), and another collection labelled simply ‘‘Bermuda’’ without definite locality, Dec. 11, 1873, by the botanists of the Challenger Expedition (K). It was collected even earlier in Jamaica, without definite locality data being recorded, probably in 1838, by Dr. Gilbert McNab (K), and more recently on the island, at Morces Gap, 1Proc. Biol. Soc.

For South America I have seen an early collection made in Uruguay: Montevideo, Dec. 1869, Gibert 932 (K). But it is in the Argentine that Centaurium pulchellum has become thoroughly established and evidently a fairly frequent weedy species in the provinces of Buenos Aires and Mendoza. Dr. Humberto A. Fabris, Museo La Plata, Argentina, has communicated a series of specimens illustrating the variations in branching, density of panicles, and leafiness among the colonies of that country. Representative collections are: .Prov. Buenos Aires: Punta Lara, Jan. 24, 1949, Fabris 273 (NO), same loc., Jan. 4, 1940, Genevieve Dawson 930 (NY); Segui, Dee. 8, 1939, A. L.

Centaurium wmbelictum Gilib., Fl. Lithuanica 1:35. 1781. Just as Centaurium pulchellum has become thoroughly naturalized in parts of South America but remains a rare adventive in North America, Centaurium umbellatum reverses the pattern with well established colonies in widely scattered parts of the United States (e.g. California and New York) but is known from South America by only a few isolated eollee- tions. The South American collections of this species that have come to my notice are: Colombia: hacienda Obonueo, Pasto, 2550 m., Dept.. Narifio, March 28, 1950, R. Espinosa 2767 (NO), where it is reported as infrequent. Chile: Apoquindo, 700 m., Dee. 1924, Clarence Elliott 102 (K); Tuseenada, 100 m., Llanguihue, Werdermann 673 (K). Argentina: Teurlingham, Prov. Buenos Aires, Jan. 1941, Helga Schwabe 193 (NO). There is some evidence that the local Brazilian phase of this natu- ralized European species may represent a distinct form. It is represented by Glaziow 6642 (K), from the Province Rio de Janiero. Lehmanniella. 3. Lehmannieila splendens (Hook.) Gilg This showy scandent gentian of Colombia with ecrimson-scarlet flowers, the subjeet of a recent review,’ was locally plentiful in partial shade along the borders of the rain forest between the settlements of ‘‘ EI Socorro’’ and ‘‘Mulatto’’ in the San Lorenzo watershed, Rio Miel drain- age, Dept. of Antioquia, 400 ft. ele., June 2, 1944, Hwan 15,787 (USNA, COL. NO), as a shrubby vine clambering over the other vegetation. Dr. Earl L. Core, with whom I travelled down the Rio La Miel to the Magdalena River, collected this plant at the same station. To one familiar with the chaparral of southern California in the spring the habit and posture of Lehmanniella recalls Penstemon cordifolius, and, like that scarlet-flowered climber, is likely visited by hummingbirds.

Lisianthus browallioides is unlike any other species of the genus, con- stituting in a sense a separate section for its singular flaring campanu- late corollas. Its shrub habit is also at varianee with the familiar species of Lisianthus, sensu stricto, of tropical America as known from Central America and the West Indies. Its true position must await a compre- hensive study of the genus as a whole with more material at hand than is available in this country alone. ; Macrocarpaea 5. Macrocarpaea glabra (L.f.) Gilg The first record for the Cordillera Central of Colombia for this species believed to be ‘‘locatized in the Bogota region’’8 is from Mendez, north- east of Silvia, Dept. of Cauca, 3000-3100 meters, Oscar Haught 5105 (US). Haught records that only one plant was seen. 6. Macrocarpaea stenophylla Gilg The third collection of this localized Peruvian species was made in dry sandy soil, on Cerro de Fraijaco (Huaui-Huni), northeast of Tambo de Ventilla, 3200-3400 meters ele., Dept. Amazonas, Peru, July 7, 1948, F. W. Pennell 15,861 (PH). Dr. Pennell records the shrub as having ‘‘eorollas pale yellow (baryta yellow).’’ All three collections studied are morphologically very uniform. 7. Macrocarpaea subcaudata Ewan, Contr. U. S. Nat.

The label bore no additional informa- tion as to the origin of the specimen over my conjectural remarks. 8. Macrocarpaea glaziovit Gilg, Bot. Jahrb. Engler 22:335. 1897. This Brazilian species was discussed in the supplement to my revision of the genus Macrocarpaea® as being a ‘‘doubtful species,’’ suggesting an affinity with M. rubra Malme but differing in certain particulars enumerated there. Subsequently I found J. F. Macbride had photo- graphed the type at the Botanical Museum of Copenhagen and the Chicago Museum of Natural History had issued the print as their num- ber 22740 in the series of photographs of type specimens. Now through the cooperation of Dr. O. Hagerup of the Copenhagen Museum I have been able to study this type, which consists of two sheets of the same collection overlapped by Macbride for purposes of photographing. Macrocarpaea glaziovii is a distinct species of the section Tabaci- foliae, differing from the two other Brazilian species, M. rubra and M. obtusifolia but more closely related to the latter species. Macrocarpaea glaziovii would be sought in my key (op. cit. 216-219) near M. obtusi- folia, from which it differs in having the usually shorter smaller corollas borne erect but particularly in haying the calyx subglabrous with only a few scattered black hairs; near M. corymbosa, from which it differs in having the calyx tube truncate or broadly cupulate at the base; and near M. pachystyla, from which it differs in having the panicle more congested, and from all of these species M. glaztovii differs in its broadly goblet-shaped corolla with its large open throat, 2 em. wide, while the corolla tube itself is short, only 2.5 em. long, and the ovate corolla lobes 8-10 mm. long, tending to be paler toward the margins. The calyx is deeply divided in the manner of Macrocarpaea guttifera but it does not otherwise resemble that Amazonian species. The type of Macrocarpaea glaziovit bears a field ticket in pencil in Glaziou’s hand [teste O. Hagerup] reading ‘‘ Tijuca, 7 O[ecto]bre 1871,’’ which then may be construed as the type locality. This locality in the State of Rio de Janeiro was visited by the English collector, George Gardner, in 1836. ®Contr. U. S. Nat. Herb. 29:248. 1948.

DrIGNAan* Examination of the series of blackbirds, Turdus merula subspp., in the collection of the United States National Mu- seum, has shown the existence of a hitherto unrecognized race in the western Chinese province of Szechwan. In honor of my friend Arthur de Carle Sowerby, the well-known natural- ist-explorer of China, I propose to call it Turdus merula sowerbyi, subsp. nov. Type.—United States National Museum No. 277524, adult [male], collected at Loshan [Kiating], Szechwan Province, China, on March 2, 1924, by David C. Graham. Diagnosis —The adult male of T. m. sowerbyi has the upper parts a uniform, unglossed sooty black (deeper and with less suggestion of brownish suffusion than appears in the same sex of JT. m. mandarinus), and the under parts a deep brownish sooty black (much darker than the grayish-brownish soot color of these parts in mandarinus). The adult female of sowerbyi has the upper parts a brownish sooty black (deeper and with less brownish suffusion than is seen in the same sex of mandarinus), and the under parts a dark rust-washed sooty brown (much darker than the rust-washed grayish-brownish soot color of these parts in mandarinus). Specimens examined.—Turdus m. mandarinus: 9 males, 8 females; T. m. sowerbyi: 7 males, 7 females. Remarks.—The only name that needed to be considered as possibly ap- plicable to the Szechwan bird is Turdus wulsini Riley (Proce. Biol. Soe. Washington, vol. 38, Nov. 13, 1925, p. 115), based upon a blackbird from Hingi [Hwangtsaopa], in extreme southwestern Kweichow Provinee. The type specimen of Turdus wulsini has proved to be a subadult of Turdus m. mandarinus. *Published with permission of the Secretary of the Smithsonian Institution. opener eT s Brena gag) Sea Be: LOR AIRE at lag i, : ow & OA ENE [ga é j fea WS Fr} ee . “hee ag BBE a 5 Tf iz .

Causry Fayetteville, Arkansas The two species of colobognath millipeds described here raise the number known from east of the Rocky Mountains to nine, representing five genera (Cook and Loomis 1928, Loomis 1936, Chamberlin 1940, Chamberlin and Mulaik 1941). The states of Louisiana, Mississippi, and Florida, from which no collections are known, should yield interesting specimens of this order, which is predominately tropical in its distribution. It is also imperfectly known in the New England States. Type specimens of Polyzonium bikermani will be deposited at the Philadelphia Academy of Natural History; those of P. mutabile are in the permanent collection of the Illinois Natural History Survey. Where no collector is mentioned, collection was by the author. I am grateful to Dr. M. W. Sanderson for the use of the specimens from the Illinois Natural History Survey. Family Polyzoniidae Genus Polyzonium Brandt This genus, represented also in Europe by several species, is known from as far north as New Hampshire and southwest into Arkansas; it doubtless will be found in most of the states east of the Rocky Moun- tains. Polyzonium bivirgatum (Wood 1864) Polyzonium bivirgatum (Wood). Cook and Loomis, 1928, Proce. U. 8. Nat. Mus., vol. 72, art. 18, p. 18, fig. 4. This paper contains a synonomy. Polyzonium rosalbum (Cope). Williams and Hefner, 1928, Ohio Biol. Survey, Bull. 18, p. 104, figs. 7 and 8. The only published figure of the gonopods of P. bivirgatum is that of Williams and Hefner; it corresponds with my specimens from Cum- berland Falls State Park, Kentucky, and Durham, North Carolina, except that there are six articles in each of the anterior gonopods and five in the posterior, and the several straight setae about midway on the seminal blade and the setae on the other articles of the gonopods are omitted. The specific distinction in the anterior gonopods is the spatulate coxal process and the attenuated seminal blade with the opening of the seminal canal subterminal. In immature specimens the opening of the canal is terminal, the coxal process is conical, and the number of body segments is presumably 33 or under. Wood (1864, 1865) reported the color of specimens believed to be from Georgia as ‘‘brown, with a fuscous stripe on each side... the 25—Proc. Brow. Soc.

My specimens from Tennessee, Kentucky, and North Caro- lina have been a delicate rose color, except for the light brown antennae, when collected. Wood and probably MeNeill described the color of pre- served material. It is very doubtful that the Michigan specimen that Bollman (1895, p. 95) described as having ‘‘antennae almost black; face and legs mottled with a purplish shade’’ is bivirgatum; these colors more nearly resemble those of mutabile, which I know only from pre- served material. The repugnatoria! secretions have a strong camphor-like odor. The extent of the range of bivirgatum is unknown; it doubtless has been confused with the two following species in some earlier publications. Polyzonium bikermani, sp. nov. (Fig. 1) This species closely resembles bivirgatum in the shape and size of the body and in the shape of the coxal process of the made gonopods; the two can be distinguished by differences in color, odor of the repugna- torial secretions, the shape of the seminal blade, and the position of the opening of the seminal canal. Male holotype. Color of dorsum cream or very light tan, lighter along lateral margins; legs and venter lighter; antennae and head light tan. Four ocelli in each of the two rows, both rows set in black, comma-shaped areas which are not confluent medially and are partly covered but visible through the tergite of the first segment. Repugnatorial secretions with but a slight trace of the camphor odor that is so noticeable in the secre- tions of bivirgatum. Each anterior gonopod consists of five articles. The first or coxal article (Fig. 1, I), scarcely visible from the posterior view, from the anterior is seen to be broad, short, and prolonged mesially into a spatu- late lobe or process (¢ p) which bears several straight, subterminal setae. The trochanter (II), also visible from the anterior view, is narrow and has a row of 6 or 7 setae across it. The prefemur (III), the largest article of the gonopod, is visible from both anterior and posterior views; about 10 setae are on its crest. The femur (IV), slightly smaller than the prefemur, and the postfemur (V), smaller than the femur, both have several setae on the crest and are visible mainly from the posterior view of the gonopod. The tarsal article or seminal blade (VI), slightly shorter and thicker than in bivirgatum, is of almost uniform width throughout its length; distally it is excised, the seminal canal opening in the middle of the excision; a few straight setae are about midway of its length. The posterior gonopods appear to be like those of other species studied. There are four setae on each of the two sternal horns adjacent to the anterior gonopods; in bivirgatum each horn has one _ seta. Width 1.7 mm., length about 12 mm., 40 segments, 4 of them legless. Female allotype 41 segments; similar in size and appearance to the male. Locality.—Devil’s Den State Park, Washington Co., Arkansas, Sept. 25, 1949; 21 specimens of different ages. Other collections have been made throughout the year in mixed decidu- ki aia Causey—Two New Colobognath Mullipeds 139 ous woods in Washington, Benton, and Carroll counties, Arkansas. This fairly abundant species is usually collected from slightly damp leaf litter; it rarely occurs under logs or rocks nor is it found in conspicuous aggregations. This is in marked contract to another colobognath milli- ped, Brachycybe lecontti, which occasionally occurs at the same collect- ing site, but prefers the lower surface of decaying stumps or logs, where it sometimes is found im brilliant rose aggregations of 100 or more individuals of various ages. It is a pleasure to name this species for Mr. J. J. Bikerman. Polyzonium mutabile, sp. nov. (Fig. 2) Distinguished from other species of the genus by the shorter and broader coxal process of the anterior gonopods of the male. Male holotype——Color in life unknown; im alcohol the dorsum is brownish yellow, paler posteriorly and along the lateral margins, with inconspicuous narrow brown bands on the posterior margins of the tergites and along the mid-dorsal line; legs and venter cream. Antennae medium brown, a narrow dark brown band on the margin of each article. Four black ocelli in each of the two rows, both rows set on black, comma-shaped areas which are not confluently medially, and which are about half covered by the tergite of the first segment. Odor of repugnatorial secretions unknown. Posterior gonopods with usual appearance. Anterior gonopods (Fig. 2) more inflated than in the other two species of the genus, but the number and general proportions of the articles is similar. Coxal process (ep) bluntly rounded, the margin thickened medially and distally in such a way that' the process almost appears uncinate; on its mesial sur- face are about 20 very short uncinate setae. Seminal blade (VI) distally truncated, flattened, slightly bent laterad; seminal canal (sc) opens dis- tally. Setae distributed as shown in figure 2. Five or six setae on each of the two sternal horns adjacent to the anterior gonopods. Width 1.9 mm., length about 13 mm., 30 segments, 2 of them legless. Locality.— Winthrop Harbor, Illinois; 18 specimens, 4 of them adult males, were collected March 17, 1933, by T. H. Frison. Additional specimens in the collections of the Illinois Natural History Survey are from the following places in Illinois: Starved Rock State Park, White Pines State Park, Mt. Carroll, Magnolia, Rocky Branch, and Dolson. The largest number of segments, 41, was found in a female.

Drake and Hottes—A New Halobatimd 143 Type (apterous male), allotype (apterous female) and many para- types (alate, apterous and dedlated males and females), taken in a salt water lagoon, Acapulco, Mexico, Aug. 3, 1951, C. J. Drake and F. C. Hottes. Named in honor of Doctora Lenora Vazquez, Entomologist in charge of the National Insect Collection, Mexico City, Mexico. The orange-brown color, pattern of black markings, absence of long hairs on genital segments and shape of male paramieres differentiate at once the new species from its congeners. Numerous other species of water-striders were collected along with T. vazquezae in the salt water lagoon near Acapulco. Biotic conditions, however, were not equaliy favorable for the multiplication of all of the different species. Based upon the number of individuals, T. vazquezae was by far the dominant form; it was present almost everywhere in the open water, including apterous and alate individuals of both sexes as well as nymphs in various stages of development. Dealated males and females were also abundant. In favorable habitats near the shore, T. vazquezae occurred in large schools of several hundred individuals that were moving about. Here and there, in the open water of the lagoon, some individuals were stand- ing and resting idly, or drifting passively with the air currents; others were gracefully cruising about in quest of prey. When disturbed, they suddenly leap and bound swiftly away by means of their long legs to make their escape. Taken in the open water along with T. vazquezae were Trepobates Taylori (Kirk.), T. trepidus D. & H., Metrobates denticornis (Champ.), Limnogonus guerini (L. & S.), and an undescribed species of Rheumato- bates. Near the shore, often under grasses or other vegetation over- hanging the edge of the water, specimens were collected of Microvelia hinet Drake, M. albonotata Champ., M. robusta Uhler, Velia brachalis Stal, Merragata hebroides B.-White and a new species of Hydrometra. Several specimens were also taken of the cospomolitan Mesovelia mulsanti B.-White. Of the above water-striders, 7. vazquezae was the only species not taken in standing or running fresh water in the vicinity of the salt water lagoon. —n— * Vol, 64, pp. 145-146 November 19, 1951 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON A NEW JUNIPER AHPID FROM WESTERN COLORADO ‘By F. C. Hortes The new species described here was collected on Juniperus utahensis growing on the Colorado National Monument near Grand Junction, Colorado. Cinara wahhaka n. sp. Apterous viviparous female: Size and general color.—Average length from vertex to tip of anal plate 1.63mm. Range in size from 1.57-1.78mm. Width of head through eyes .51-.57mm. Color of head, thorax and abdomen dark brown. Thorax with just a suggestion of two dusky lateral stripes. Mounted specimens show the thorax with darker irregular shaped spots arranged in trans- verse rows. Similar spots are found in two transverse rows on the first two abdominal segments. Smaller and more rounded spots are arranged in, two rows on each side of the remainder of the abdomen. Abdominal spiracles surrounded by small brownish spots. Spots on thorax and dorsum of abdomen suggestive of wax glands, but there is no powder or pulverulent matter present, the entire body presenting a highly pol-- ished appearance. First two antennal segments concolorous with head or slightly dusky. Antennal segments three, four and base of five pale, remainder of antennae dusky. Femora shading from tan to brown with apical regions darker. Tibae pale except for apical regions which are concolorous with tarsi, which are dusky. Cornicles dusky, cauda and anal plate, and band just anterior to cauda the same. Head and appendages.—Proportional lengths of antennal segments as follows: III .24-.28, most common length .27mm., IV .10-.11, most common length .lJmm., V .128-.143mm., always longer than IV. VI .042- .057mm + .028mm. Secondary sensoria distributed as follows: III none, four none, five one. The primary sensorium on six large, round, free from hair ring with two or three marginal sensoria at the side, these are not always easily seen. The unguis is rather thick and stubby. Hair on antennae exceedingly sparse, fine and short, that on third segment . being considerably less than half width of segment in length. Occular ‘anes tubercles present, but poorly developed. Head with a median suture, Hair on head exceedingly sparse, fine and even shorter than hair on an- tennae, not always sharp pointed. Vertex and anterior margin of head often free from hair. Rostrum as a rule attaining cornicles. Thorax.—Length of hind tibiae varying from .958-1.07mm. Hind tarsi 243mm. in length. First segment of hind tarsus with about nine hair, on inner side, none on outer. Outer surface of hind tibiae with a few widely scattered fine short hair, hair on inner surface of hind tibiae not i numerous and considerably shorter than width of tibiae. ae } Abdomen.—Base of cornicles small in comparison to diameter of rim, “4, j varying from .10-.12mm. Base of corniclues almost free from hair. : Zo Hair when present never more than six and confined for the most part nega to extreme edge of base. It is common for a cornicle to have only two ia. at $ # ON ee Rey oy See ee eT) iw uw INSTT yy > e ow f f b 27—PrRoc. Bion. Soo.

Hair on abdomen with the exception of that on anal plate and cauda very sparse, variable in length, but for the most part very short and not always sharp pointed. Hair on cauda and anal plate long, rather fine, present in moderate amount. The cauda is rounded but rather narrow. Oviparous female: In most respects this form is similar to that of the apterous viviparous female. Length carying from 1.781-1.85mm. Width across eyes .54-.60mm. Third antennal segment .114-.157mm. Fourth antennal segment varying from .114-.148mm. Fifth antennal segment varying from .43-.157mm. Sixth antennal segment varying from .042 + .028mm.-.042 + .042mm. Hind tibiae 1.1lmm. in length. Hind tarsi .248mm. long. Hind tibiae swollen and rather bumpy in middle region. Sensoria rather tuberculate and difficult to see because of lack of color in this region of tibiae. Hair on tibiae more abundant and longer than that found on tibiae of apterous viviparous female. Holotype apterous viviparous female Sept. 9, 1951. Morphotype oviparous female Oct. 2, 1951. Holotype and morphotype deposited in the United States National Museum. Paratypes taken on following dates: Sept. 9, 18, 23, and Oct. 2, 1951. On Juniperus utahensis. This species was only located once in nature although much time was spent in trying to locate other colonies. Cinara wahhaka feeds on the small green twigs (leaves) of Juniper. It appears to be closely allied to Cinara burrilli (Wilson), Canad. Ent. 51, p. 42, 1919, from which it differs in size, length and amount of hair, size of cornicles, and much fewer hair on cornicles and perhaps in color and lack of pulverulence. Cinara burrilli (Wilson) Through the kind and much appreciated cooperation of Prof. M. A. Palmer and Dr. G. F. Knowlton I have been enabled to study some of the original material of this species collected by Profg. Burrill. I ques- tion if Wilson saw these specimens at the time he described the species, but they unquestionably form a part of the cotype material. Wilson’s original description was based in part on notes taken by Burrill in the field. There is much in the original description that does not fit the specimens at hand and I am almost convinced that the description was based on two species. I have not seen the type, but Prof. Palmer has sent me measurements taken from it, which indicate that it does not differ from the cotype material seen by me. The apterous viviparous females differ from the description in the following respects: They are smaller, being about 2.5mm. long, not 3mm. The third antennal segment is free from secondary sensoria, and varies in length from .30-.35mm., not .42mm. The base of the cornicles is not as small as the description leads one to suspect. The hair are not short, neither are they incon- spicous. I suspect that the color was not black. Wilson quotes Burrill as saying that the species feeds on the bark on the underside of the limbs. The slides labeled by Burrill state that the specimens were ‘‘taken on the upper twigs.’’ The color is described as ‘‘black with pruinose patches which produce a ealico effect.’’ It is further stated that they greatly resemble the bark in color. The mounted specimens suggest that the color was something other than black, and I question if the specimens could be black and resemble the bark, even if the pruinose condition were present, and still live on the twigs. Can it be that Burrill took his color and habitat notes from the species de- seribed by Gillette and Palmer in 1924 and named Lachnus sabinae?

April 25, 1952 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON MISCELLANEOUS NEW NORTH AMERICAN CENTIPEDS OF THE ORDER LITHOBIIDA By RateH V. CHAMBERLIN AND YU-HSI M. WANG The new genera and species of Lithobiid centipeds described in the present paper were noted in the course of examination of several miscellaneous lots of chilopods in the collection of the senior author where all types are for the present de- posited. Family LITHOBIIDAE Genus CALCIBIUS, new genus In general agreeing with Oabius, like which it has the tarsi undivided in all but the posterior legs. Articles of antennae 20 and prosternal teeth 2 + 2. None of the dorsal plates produced. Separated from Oabius because of the presence (in the male only ?) of a low swelling or lobe on the mesal side of the distal end of the fourth joint of the anal legs, this lobe bearing an especially large mesally directed spine or spur. Generotype.—Calcibius calcarifer new species. Calcibius calcarifer new species General color pale yellow throughout. Antennae short; articles 20. Ocelli in two short series, thus, 2,2. Prosternal teeth small, pale, 2 + 2. : Ventral spines of the anal legs, 0,1,3,3,0; dorsal spines, 1,0,2,0,0; in addition, at least in the male, a much larger and characteristic spine : borne at distal end of the fourth joint, the spine extending mesad and fi curving somewhat proximad. Dorsal spines of the penult legs 1,0,2,1,1. // <—& Length, 6.2 mm. Hf Sx Locality.— Washington: Ellensberg. i Type.—One male taken Aug. 29, 1929, by R. V. Chamberlin. Enarthrobius oblitus new species Dorsum light brown, the caudal border of principal tergites darker. \ = : Legs dull yellow. Head and prehensors more or less organge in color. \\ af Antennae of moderate length, the articles mostly 26 in number. Ocelli small and pale. Typically in three longitudinal series; e.g., 1 + 5,5,5. Prosternal teeth 2 + 2. Posterior angles of ninth, eleventh and thirteenth dorsal plates pro- duced. Dorsal spines of anal legs, 1,0,3,1,0; ventral spines, 0,1,3(4),2,1; the claw single Dorsal spines of penult legs, 1,0,3,1,1; central spines, 0,1,3,3,1% one small accessory claw present. Dorsal spines of the 9—Proc. Brow. Soc. WASH., Vou. 65, 1952 (55) abe 8 1952 56 Proceedings of the Biological Society of Washington thirteenth legs, 1,0,3,1,1; ventral, 0,1,3,3,2. None of the coxae laterally armed. Ventral spines of first legs, 0,0,2,3,2. Coxal pores slightly elliptic; 5,6(5),6,5. In the male the fourth joint of the anal legs bears at its distal end above a small but distinct lobe. The claw of the genital forceps of the female tripartite; the basal spines 2 + 2, these long and subcylindrie to the short, acute tip. Length, 18 mm. Locality.—California: Claremont. Type.—Three males and two females. In lacking lateral spines on the posterior coxae and in most other respects close to EZ. bullifer Chamb., occurring in South Carolina. Sep- arated from that species on the basis of differences in the spining of the legs, the new species having the ventral spines of the anal legs 0,1,3,(4),2,1 instead of 0,1,3,2,0 and the ventral spines of the first legs 0,0,2,3,2 instead of 0,0,1,3,1. Nadabius pluto new species Dorsum light chestnut, head and prehensors darker. Legs yellowish. Antennae of moderate length, composed of 20 articles which decrease in length distad to the penut article, the ultimate article being long as usual. Ocelli in three series; eg., 1 + 4,4,3, with the single ocellus much the largest. Prosternal teeth, 2 + 2. Ventral spines of first and second legs, 0,0,1,3,2; dorsal spines, 0,0,1,2,1. Dorsal spines of twelfth and thirteenth legs, 1,0,3,1,0. Dorsal spines of penult legs 1,0,3,1,1; ventral spines, 0,1,3,3,2; the claw armed. Dorsal spines of anal legs, 1,0,3,1,0; ventral spines, 0,1,3,3,1; the claw single. Last two pairs of coxae laterally armed. Anal legs of the male with tarsus bearing a typical keel at distal end above. Claw of female genital forceps tridentate; the basal spines 2 + 2, these rather short and broad. Length, 9-10 mm. Locality Montana: Hell Gate River. Type.—Several males and females taken Aug. 13, 1929, by ue V. and Edith 8. Chamberlin. Closely related to N. mesechinus Chamb. of Oregon, but differing in having the ventral spines of the anal legs 0,1,3,3,1 instead of 0,1,3,2,0 as well as in the spining of the first two pairs of legs. Nadabius vaquens new species Dorsum light brown, the venter and legs paler as usual. Antennae short, composed of 20 articles. Prosternal teeth 2 + 2, small; the margin running obliquesly from the outer tooth on each side in a laterocaudal direction. None of the dorsal plates produced. Ventral spines of the anal legs 0,1,3,2,0; dorsal, 1,0,3,0,0; claw single. Ventral spines of penult legs, 0,1,3,3,1; dorsal spines, 1,0,3,1,0; claw armed. None of the coxae laterally armed.

Female holotype and one male. In form of basal spines of the female gonopods resembling Taiyubius rather than typical Paitobius but differmg from the known species of the former genus in not having the posterior corners of the ninth tergite at all produced. It differs from the previously known species of Paitobius, subgenus Tunabius, in having the anal claw single and in having the ventral spines of the penult legs 0,1,3,3,2. Pokabius (Pokabius) iosemiteus new species General color yellow, the legs paler. Antennae short. Ocelli in a principal series of 5 or 8 above which one or two much larger ocelli. Prosternal teeth pale, small, 2 + 2. None of the dorsal plates with posterior angles produced.

Posterior coxae not laterally armed. The fourth joint of the anal legs in the male especially crassate, the dorsal process at its proximal end in the form of an exceptionally long, horn-like process which curves mesoproximad above its base, its end flat- tened, with margin rounded and setose. Claw of the female gonopods tridentate, the teeth not pronounced. Basal spines 2 + 2. Length, 8-9.5 mm. Locality. California: Yosemite National Park. Type.—One male and one female. Probably nearest to P. disantus Chamb., occurring in Los Angeles and adjacent counties, but widely different in the prolonged process of the fourth article of the anal legs in the male. Genus PLANOBIUS, new genus Apparently closely related to Nampabius, but a much larger form than species of that genus, differing in having the posterior coxae spines both laterally and dorsally and in the stronger spining of anal and penult legs. These legs similarly bear two claws. The male is similar to Nampabius in bearing a characteristic process at the distal end of the 58 Proceedings of the Biological Society of Washington fifth article of the penult legs, but the process arises well down on the side of the joint rather than dorsally. Generotype.—Planobius aletes new species. Planobius aletes new species The articles of antennae 20 in number. Ocelli few, pale. Prosternal teeth 2 + 2. Posterior angles of none of the dorsal plates produced. Ventral spines of anal legs 0,1,3,3,1; dorsal, 1,0,3,1,0; claws 2. Ven- tral spines of penult legs (in the male), 0,1,3,2,0; dorsal, 1,0,3,1,1; elaws 2. Last two pairs of coxae armed laterally as well as dorsally. Penult legs of the male with first joints conspicuously inflated but the last two joints abruptly thinner, the fourth joint thickest. The process of the fifth article located at the distal end midway down the side and projecting alongside of base of the sixth article, the process widening a little clavately distad and truncate at the end. Length, about 13 mm. Locality.—Not recorded. Type.—One male. Sigibius siopius new species Brown to chestnut, with posterior end of body lighter and the corre- sponding legs pale yellow. Articles of antennae typically near 25. Ocelli very few, mostly two or three in a single series. Prosternal teeth normal. Differing from the related American species in having the claw of the anal legs single. Ventral spines of anal legs 0,1,1,1,0; dorsal, 0,0,1,1,0; claws 2, the accessory claw small and fine. Dorsal spines of thirteenth legs, 0,0,1,0,0; ventral, 0,1,1,1,1. Claw of genital forceps short and proportionately broad, bidentate, the teeth short. Basal spines 2 + 2. Length, 6 mm. Locality—Utah: Provo (May 22, 1942) and Salt Lake Valley along the Jordan River (May 11, 1946). Type.—Many specimens of both sexes. Simobius opibius new species Readily distinguished from S. ginampus, the generotype, in having the prosternal teeth 4 + 4 instead of 2 + 2, as well as in having the ventral spines of the penult legs 0,1,3,3,1, instead of 0,1,3,3,2, with two claws instead of three, and apparently also in having the ventral spines of the anal legs 0,1,3,3,0, but the spine on the fifth joint may possibly have been lost from the type. The anal and penult legs in the male are crassate, the anal legs otherwise unmodified; the dorsal eminence at distal end of fifth joint of the penult legs low and broad, shaped much like the typical keel in the anal legs of Nadabius, thus contrasting with the sub-cylindrical process on ginampus. Length,—10 mm. Locality.—California: Muir Woods. Type—Two males and an immature female taken Sept. 5, 1927. Chamberlin and Wang—North American Centipeds 59 Sozibius mullanua new species General color yellow, with head, antennae and prehensors darker. Ocelli large, few in number, being typically 2,2 or 1 + 1,2. Third joint of first pairs of legs having but 2 dorsal spines. Ventral spines of anal legs 0,1,3,2,0; dorsal, 1,0,3,1,0; claw single. Ventral spines of penult legs 0,1,3,3,1; dorsal, 0,0,3,1,0. None of coxae laterally armed. Length, 11 mm. Locality,—Idaho: Mullan. Type.—One male taken Aug. 17, 1929, by R. V. and E. S. Chamber- lin. This is the first record of Sozibius from west of Arkansas. The present species is distinguishable from S. pennsylvanicua, apparently the most clearly related to it of the known forms, in lacking a lateral spine on the posterior coxae, in having the ventral spines of the anal legs 0,1,3,2,0 instead of 0,1,3,3,2, and the ventral spines of the first legs 0,0,1,1,1,1 instead of 0,0,2,2,1.

First article enlarged, excavated on mesal side at base as usual. Length, 15 mm. Locality—Unceertain, but probably Utah or an adjacent area. Apparently an aberrant member of Gosibius among the species of which it is distinct especially in the larger number of prosternal teeth and the lesser number of antennal articles. Gosibius (Gosibius) submarginis new species The type, which is probably not in full color, is pale yellowish throughout. Articles of antennae 23. Ocelli small; 1 + 4,3,3. Prosternal teeth small, 3 + 3; the ectal spine slender but stouter than the ordinary setae, well removed from the ectal tooth on each side.

BAYER* Associate Curator, Division of Marine Invertebrates, U. S. National Museum Among the octocorals obtained by the U. S. Fish Commis- sion steamer ‘‘ Albatross’’ during the Northwestern Pacific Cruise of 1906 are two new species of primnoid corals belong- ing to the subfamily Calyptrophorinae. Because of the primi- tive characters which they possess, both are of more than usual interest and may serve to shed more light upon relationships within the Primnoidae. The members of this family, especially those native to the waters of Japan, have been studied exten- sively by the late Kumao Kinoshita, whose phylogenetic con- siderations concerning primnoids were published in the Dobut- sugaku Zasshi (Tokyo) during 1908 and 1909. I am especially indebted to Mr. Hirohiko Otsuka, of Tokyo, who has trans- lated these papers from the original Japanese, thus making their contents available to me for this and other studies in progress.

Calyptrophora (Arthrogorgia) Kinoshita 1908, p. 59; Kinoshita 1909, aie This genus, originally proposed by Kiikenthal for the species Arthro- /, gorgia membranacea Kiikenthal 1908 [=Calyptrophora ijimai Kinoshita |; 1907], was distinguished from Calyptrophora Gray on the basis of its three abaxial and two adaxial pairs of infrabasal scales and its regular ||“: pinnate branching. The two new species described below characteristi- |) = cally possess multiple infrabasals, but are not regularly pinnate in branching. However, since the manner of branching in this family is so diverse that it can only be considered secondary to the zooidal spicu- lation, these new species will fall within the limits of the genus Arthro- gorgia, a modified diagnosis of which may read as follows: Primnoids with zooids in whorls; zooid body enclosed by two pairs of large abaxial scales; infrabasals more than two pairs; distal adaxial *Published with the permission of the Secretary of the Smithsonian Institution. 10—PRoc.

S5rzer In the course of field work sponsored by the Office of Naval Research in northern Alaska, during the summer of 1951 specimens of small mammals were obtained at several points on the Arctic Slope. Among these is a population of Microtus oeconomus that is recognizably distinct from other named kinds of the same species. In the following description, capitalized color terms are from Ridgway (Color Standards and Color Nomenclature, 1912); all measurements are in millimeters. This new vole is named for Dr. Raymond M. Gilmore. It may be called : Microtus oeconomus gilmorei subsp. n. Type—Male, adult, skin and skull, United States National Museum No. 293109; Point Lay, (163° 04’ W Long. and 69° 46’ N Lat.), Alaska; obtained 4 July 1951, by H. W. Setzer, original No. 2396. Range.—Arctic Slope of Alaska from Point Lay on the west, at least to Umiat on the east and from the Meade River on the north at least to the crest of the Brooks Range on the south. Specimens examined.—54, all from Alaska: Point Lay, 27; Utukok River, 200 miles SW Point Barrow, 5; Mouth of Chandler River, 1; Anaktuvuk Pass, 16; Umiat, 2; Killik River, 3. Diagnosis.—Entire upper parts between Snuff Brown and Bister with a moderate admixture of black hairs; color of upper parts shading into the grayish white color of the belly low on the sides; belly but lightly washed with buff; dorsal surfaces of hands and feet with a thin brown- ish line; tail with a blackish brown dorsal stripe, remainder buffy and with a small penicillate tip; soles and palms naked; all hairs plumbeous at base. Skull robust; zygomatic arches robust and rather angular an- teriorly; rostrum rather broad; nasals quite flat and flaring anteriorly; posterior portion of skull broad and rather flat; auditory bullae well inflated ventrally; maxillary teeth heavy. Comparisons. — Microtus oeconomus gilmorei differs from Microtus oeconomus macfarlani, as known from the Anderson River, Northwest Territories, Canada, as follows: Color paler and more yellowish; auditory bullae sub-acute instead of rounded posteriorly and acute instead of sub-acute anteriorly, more inflated ventrally, thus presenting the appear- ance of a longer, narrower bulla; zygomatic arches flaring anteriorly as opposed to nearly parallel; upper incisors more recurved; maxillary teeth heavier; skull averages larger. e, From WMicrotus oeconomus operarius, as known from St. Michael Vie 12—Proo. Bion. Soo. WASH., VOL. 65, 1952 (75) ff 76 Proceedings of the Biological Society of Washington Alaska, M. o. gilmorei differs as follows: Color paler, more yellowish; tail somewhat shorter; auditory bullae larger and inflated instead of small and rather flattened, ventrally; longer heavier maxillary tooth- row; nasals wider anteriorly; interparietal generally narrower in width; skull larger in all measurements taken in animals of comparable age and sex. Measurements.—Averages and extremes of four males and six females, all adult, from the type locality, are respectively: Total length 171.3 (161.0-181.0), 164.8 (159.0-170.0) ; length of tail 39.7 (37.0-45.0), 38.8 (35.0-42.0); length of hind foot 19.8 (18.0-21.0), 18.8 (17.0-20.0) ; length of ear from notch 13.3 (13.0-14.0), 13.0 (11.0-14.0) ; eondylobasal length 27.8 (27.5-28.4), 26.8 (26.4-27.5) ; palatal length 15.1 (14.8-15.6), 14.6 (14.3-15.2); greatest zygomatic width 15.3 (14.6-15.9), 14.4 (13.8- 14.9); least interorbital width 2.8 (2.7-2.8), 2.9 (2.7-3.1); length of nasals 6.95 (6.7-7.5), 6.5 (6.2-6.8); width of rostrum immediately an- terior to zygomatic processes of maxillae 2.5 (2.4-2.6), 2.3 (2.0-2.5); greatest width of braincase 11.6 (11.2-11.8), 11.4 (10.6-11.9); alveolar length of maxillary toothrow 5.6 (5.5-5.8), 5.5 (5.2-5.7). Remarks.—As is typical of the species Microtus oeconomus in North America, all specimens were taken in extremely wet tundra areas. The most numerous population was found at sea level at Point Lay but other specimens were obtained at an elevation of 2000 feet near Meat Mountain on the Utukok River and at a somewhat lower altitude at the mouth of the Chandler River. Intergradation is demonstrated with Microtus oeconomus macfarlani in specimens obtained at and near Anaktuvuk Pass. This is evidenced by an intermediacy in the shape of the auditory bullae and length and robustness of the maxillary toothrow. It is probable that the name Microtus oeconomus endoecus Osgood is valid. This assumption is based on the examination and comparison of specimens from the Yukon drainage area which represent the subspecies M. o. endoecus, and specimens from the Mackenzie area and the Ander- son River country of Canada which represent the subspecies M. 0. mac- farlani. Certain characters of the toothrows, the auditory bullae and the zygomatic arches appear to separate the two populations, but until additional material, particularly that exhibiting a wider range of age groups, is available, it seems best to preserve the current nomenclatorial status of M. 0. endoecus as a synonym of MW. o. macfarlani.

VIRGINIA: New Market, March 16, 1941, Dr. Lincoln C. Pettit, 7 2’s and 14, from dead leaves on ground. E. virginianus belongs with those reticulated species which have the head nearly free of such reticulation between, and for a short distance behind, the postocular setae. From them it may readily be known by the presence on the third antennal segment of only one sense-cone on the outer surface and of two knobbed dorsal apical setae, as well. as by the relatively short postocular and other setae. 673 VoL. 65, pp. 81-82 April 25, 1952 PROCEEDINGS OF-THE BIOLOGICAL SOCIETY OF WASHINGTON A NEW COTTON RAT (GENUS SIGMODON) FROM MORELOS, MEXICO By Rosert J. RUSSELL The Texas Cooperative Wildlife Collection of the Agricul- tural and Mechanical College of Texas contains a small series of adult cotton rats, Sigmodon hispidus, from the Mexican State of Morelos. Previously, only immature specimens of this species were known from Morelos and these were referred to Sigmodon hispidus mascotensis Allen (see Bailey, Synopsis of the North American Species of Sigmodon. Proc. Biol. Soe. Washineton, 15:101-116, 1902). Examination of near-topo- types of Sigmodon h. mascotensis from northern Jalisco and southern Nayarit, as well as representative specimens of other adjacent subspecies. reveals that the cotton rat of Morelos belongs to an heretofore unrecognized subspecies for which I propose the name Sigmodon hispidus obvelatus new subspecies Type. Adult female, skin and skull, no. 4921, Texas Cooperative Wildlife Collection, Agricultural and Mechanical College of Texas; 5 miles 8S Alpuyeca, 3700 feet, Morelos, Mexico; collected by W. T. Smith, August 16, 1949, original no. 38. Distribution. Known from several localities in eastern and western Morelos; probably occurs in the adjacent arid sections of Guerrero and Puebla. Limits of range unknown. Diagnosis. Size medium for species (see measurements); tail long; hind foot small. Color: Pale, upper parts near Light Ochraceous-Buff (capitilized color terms after Ridgeway, Color Standards and Color Nomenclature, Washington, D. C., 1912) washed with black; under parts creamy-white, almost obscuring the Plumbeous bases of the ventral hairs; creamy-white extending over underside of legs; hind foot whitish ahove; front foot buffy above; nose yellowish. Skull: Medium in size, narrow, shallow, delicately constructed, and lightly ridged; nasals relatively long; auditory bullae small; interpterygoid fossa wide anteriorly and constricted posteriorly; anterior palatine foramina parallel sided, not constricted posteriorly; interparietal convex posteriorly; molar teeth actually and relatively small; interorbital constriction relatively wide. Comparisons. From S. h. mascotensis, which I judge to be the most closely related subspecies, S. h. obvelatus differs as follows: Body smaller (total length averaging 292 as compared with 325); color slightly paler above and more nearly white below, especially paler facially; hind foot whitish rather than buffy and smaller (length 33 as compared with 38) ; skull smaller (greatest length averaging 35.6 as compared with 38.1), Cc shallower, especially in orbital region, more delicate in structure; zygo-)) ~: matic breadth less (19.3 as compared with 21.1); auditory bullae actu-) | ally and relatively smaller; molar teeth actually and relatively smaller; \\ ~ 14—Proc. BioL. Soc. WASH., Vou. 65, 1952 (81) 82 Proceedings of the Biological Society of Washington anterior palatine foramina shorter (7.9 as compared with 8.7); hard palate shorter and narrower. From 8S. h. berlandieri, which occurs to the north, 8. hk. obvelatus differs as follows: Tail much longer; color of upper parts less pinkish; under parts more heavily washed with white; tail darker above; skull narrower, more delicate in structure, and less heavily ridged; zygomatic breadth less; interpterygoid fossa wider; rostrum narrower; interparietal eonvex posteriorly rather than straight; interorbital construction rela- tively broader. From S. h. inexoratus, which occurs to the northwest, 8. h. obvelatus differs as follows: Body larger (total length averaging 292 as compared with 268); tail longer and less densely haired; color of upper parts paler (not so blackish); skull longer (greatest length 35.6 as compared with 33.3); maxillary arm of zygoma longer and more decurved; inter- pterigoid fossa wider; anterior palatine fordlamina parallel-sided, not constricted posteriorly; hard palate shorter. Close comparison with S. h. toltecus, which oceurs to the east, is not necessary; however, S. h. obvelatus differs as follows: Body larger; tail longer; hind foot longer (33 as compared with 29); color of upper parts paler; under parts more whitish; skull larger and deeper; interpterygoid fossa much wider; molar teeth larger; auditory bullae larger. Measurements. The type followed by an adult male (in parentheses) from Jonacatepee: Total length, 295 (288); length of tail, 147 (132); length of hind foot, 34 (35); greatest length of skull, 36.0 (35.2) ; zygo- matic breadth, 19.1 ( ); length of nasals, 14.5 (13.8); interorbital breadth, 5.5 (5.4); breadth of braincase, 14.0 (14.2); depth of brain- ease, 14.1 (13.5); length of palatine foramina, 8.1 (7.7); length of hard palate, 6.0 (6.3); length of molar tooth-row, 6.5 (6.6). Specimens examined. Four, all from Morelos, as follows: 5 mi. S Alpuyeca, 2; 6 mi. W Yautepec, 1; 2 km. S Jonacatepee, 1. Remarks. S. h. obvelatus inhabits the arid lowlands of Morelos, which are distinguished by a peculiar arid tropical scrub vegetation and heavy soils. This area is a part of the Rio Balsas drainage, and is bounded on the north by the high transverse voleanic mountains that form a barrier to the distribution of Sigmodon hispidus. S. h. atratus Hall is here regarded as a synonym of S. h. inexoratus Elliot. Dr. E. Raymond Hall has compared the two subspecies and in- formed me that they are identical. He unfortunately overlooked S. h. inexoratus when he prepared his description of S. h. atratus. It should be noted that S. h. mascotensis is actually larger in size of both body and skull than previously reported. The adult specimens of this subspecies used for comparisons here are larger than those re- ferred to in Bailey’s account (loc. cit.) of S. h. mascotensis. Bailey mentions one ‘‘very large’’ specimen from Querendaro, Michoacan. S. h. mascotensis approaches S. h. major in size; however, the two sub- species are easily separated by cranial characteristics. I'am indebted to Dr. E. Raymond Hall and Rollin H. Baker, Museum of Natural History, University of Kansas, for the use of specimens under their care, and to Dr. H. E. Anthony and Mr. George G. Goodwin, American Museum of Natural History, for the loan of additional speci- mens.

CHAMBERLIN In a collection of centipeds made by Borys Malkin in 1951 in Alaska are specimens of a new Brachygeophilus which were found near the lower tide mark on Kuiu Id. A few other geophiloid forms have been recorded as similarly living be- tween the tide marks and as thus surviving frequent and pro- longed submergence under water, most of these belonging to the family Schendylidae whereas the present species pertains to the Geophilidae proper. Brachygeophilus admarinus n. sp. Head longer than wide (13:11), widest back of middle. Labrum as a whole concave; median division straight or slightly convex, bearing mostly 5 long, acuminate, basally dark teeth; lateral divisions closely pectinate. First maxillae with palpus and inner process both conically pointed and each having typically 5 setae on its ventral face; syncoxite bearing a lappet on each side. Claw of the second maxillae smooth; coxae broadly united with no trace of a median suture. Prosternum of prehensors unarmed, and with no sclerotic (chitinous) lines. Claws of prehensors when closed not attaining front margin of the head; claws with a minute tooth or tubercle at base. Anterior sternites each with posterior margin sclerotized in an edge that fits into a transverse notch on anteriar border of the succeeding sternite. No ventral pores were detected. Last ventral plate broadly trapeziform, the sides strongly converging caudal. Coxal pores mostly 6 on each side. Anal pores present. Anal legs each with a well developed claw. Anal legs of female slender, those of male crassate. Number of pairs of legs 47 in both sexes. Length, near 25 mm. Locality. Redd Bay, Kuiu Id., Southeast Alaska. July 23-25, 1951.

J. DRAKE AND F. C. HortTes While collecting aquatic Hemiptera in Mexico during the past summer (1951), the authors netted 6 specimens of a robust water-strider of the genus Vela Latreille, which was much more active and behaved differently after capture in the net than its congeners. An examination of the specimens showed that the last two segments of the male venter were singularly developed and greatly modified as described in Velia annulipes Champion. Further studies also revealed that the male parameres were not the same as the left paramere of the male type figured by Hungerford in 1929. On account of the differently shaped parameres and other characters, it seemed advisable to have the Mexican species checked with the types of V. annulipes Champion in European museums. The writers are greatly indebted to Dr. R. J. Izzard for notes and an outline drawing of the paramere of the male type from Guatemala in the British Mu- seum. Dr. Max Beier of the Naturhistorisches Museum at Vienna has kindly loaned us the male cotype from Mexico (ex. collection of Sig- noret) as listed beneath the original description. Dr. H. B. Hungerford of the University of Kansas has also kindly given us some data relative to the types of V. annulipes, which he secured several years ago while studying the types of American aquatic Hemiptera deposited in Eu- ropean Museums. The results of our findings are discussed below under the species concerned, beginning with the description of the Mexican veliid as new to science. Velia alvaradana, sp. new (Fig. a) Apterous male: Large, robust, subfusiform, dark ferrugineous-fuscous with several small groups of glistening silvery hairs. Antennae dark brown with second segment very widely banded with pale testaceous be- yond the base (basal dark part much shorter than band; apical part beyond the band darker and approximately equal to the band in size). Pubescence short, very dense, brown. Body beneath dark fuscous-brown with posterior part of venter and genital segments brown. Wing pads tiny, snowy white. Macropterous forms unknown. Size: Length, 5.60 mm.; width, 1.65 mm. Head: Width across eyes, 1.10 mm.; interocular space, 0.38 mm. Head densely pubescent with scattered long dark hairs, the hairs denser and lighter along inner margins of eyes. Impressed median line distinct, black, convex between the eyes. Rostrum testaceous, becoming blackish apically. Antennae long, slender, shortly pilose with scattered longer 16—Proc. Brot. Soc. WASH., Vou. 65, 1952 (85) 86 Proceedings of the Biological Society of Washington hairs on distal two segments; segment I modertately swollen, slightly bowed; II much slenderer, thicker than next two; III and IV quite slender, equal in thickness; formula—I, 136; II, 74; III, 80; IV, 68. Thorax: Pronotum blackish with a large central brown area a little back of narrow collar, with a conspicuous small patch of glistening silvery hairs on each side of pale patch; without humeral elevations, with posterior margin slowly broadly rounded, the median length and width across humeral angles nearly equal (120:128). Rest of dorsal part of thorax almost entirely concealed by pronotum. Legs: Long, moderately stout, pubescent, clothed beneath with longer pale hairs; femora of about equal thickness. Anterior legs—broadest near base, a very narrow band at apex and another subapical band pale testaceous, beneath beset with many short dark spicules, which are not arranged in definite rows; tibiae with a narrow preapical and a narrow subbasal bands testaceous, beneath with two dense rows of short black teeth (rows placed very closely together); tarsi dark brown, hairy; segment I very short and about half as long as second; III nearly three times as long as second. Middle legs with markings similar to fore legs but with the basal testaceous area of femora much smaller; femora beneath with two rather sparse rows of short blunt black teeth (one row sometimes incomplete) ; tibiae beyond the middle beneath with a sparse row of seven or eight long dark hairs; tarsi beneath with hairs a little longer than the diameter of segments, formula of segments—I, 8; II, 35; III, 42. Hind legs with color markings similar to intermediate legs; coxae and trochaanters denticulate beneath; femora beneath with two rows of larger and stouter black teeth; tibiae denticulate beneath, the olack teeth tending to be arranged in two irregular rows, formula of segments—I, 8; II, 35; III, 42. Tarsi of all legs with basal part of third and second segments largely testaceous. Abdomen: Dorsal surface dark ferrugineous with several patches of silvery hairs on last four segments; connexiva with silvery hairs on outer part of joints between segments; venter with hind margin of penultimate segment broadly produced posteriorly with the median part narrowed and terminating in a large tubercle like process, which extends posteriorly as far as the hind margin of the ultimate segment. First genital segment beneath very strongly abruptly depressed from near the base to apex so as to leave the apical part of segment much thinner than the basal. Left paramere very broad and modified as in figure 1. Right paramere of similar size and shape. Apterous female: Broader and much stouter than male, but with color and markings quite similar. Antennal formula same as in male, second segment also broadly banded with testaceous. Last segment of venter not quite twice as long as preceding segment, becoming a little narrower posteriorly. Other characters as in male. Type (male), allotype (female) and 3 paratypes, Puebla, Mex., July 20, 1951, taken under thinly overhanging vegetation near the water’s edge in a small river. Paratype, one specimen, Alvarado, Mex., collected near the shore among aquatic vegetation in a small stream. This striking species may be separated at once from V. annulipes by the banded second antennal segment and shape of the parameres (fig. a). It was taken in company with V. pueblana Drake and V. brachialis Stal. When netted, V. alvaradana is extremely active and runs about swiftly Drake and Hottes—Mezican Veltidae (Hemiptera) 87 trying to escape. It is much more agile and faster than V. brachialis Stal. Another species, V. pueblana, lives in the same type of habitat and is almost as active in the net as V. alvaradana. Velia verana, sp. new (Fig. b) Velia annulipes Champion, Biol. Centr.-Amer., Rhynch., 2:142. 1898 (in part). The name V. verana is here proposed for the second specimen (male, cotype) of V. annulipes Champion, bearing the labels ‘‘ Mex., collection of Signoret,’’ ‘‘cotype,’’ ‘‘V. annulipes Champ.’’ as determined by Champion in the Mus. Vind. Caes. As may be noted in the figure, the left male paramere (b) is very different from the male type of V. an- nulipes (c), and more closely related to V. alvaradana (a). V. verana differs from V. alvaradana in its smaller size (5.00 mm. long), uniformly colored second segment of antennae (with a very broad testaceous band in V. alvaradana) and shorter antennae. Antennal formula—I, 61; II, 36; III and IV wanting. Winged form and female, unknown. We are indebted to Dr. Max Beier for loaning us this unique specimen in the Naturhistorisches Museum at Vienna. The parameres of this species and V. alvaradana were drawn by Mrs. Richard Froesch- ner. Velia annulipes Champion (Fig. c) Velia annulipes Champion, Biol.

Wing, 51 mm.; tail, 19; exposed culmen, 7; culmen from base, 10.5; tarsus, 14.5. Remarks: Sexes different in coloration. Wings shorter than in strio- latus. Range of measurements: six adult males—wing, 51-52 (51.3) mm.; tail, 19-20 (19.6); culmen from base, 10-10.5 (10.6); one adult female— wing, 51; tail, 21; culmen from base, 10.5. Measurements of striolatus from Ecuador’: six adult males—wing, 53-56 (55); tail, 19-20 (19.5); culmen from base, 10-11 (10.2); six adult females—wing, 49-54 (51); tail, 20-23 (20.6); culmen from base, 10-11 (10.2.) The female differs from the male in having the upper parts uniformly Yellowish Olive; the carmine breast stripes are lacking; the breast 1s Isabella Color with fine whitish shaft stripes while the abdomen is paler brownish with wider stripes; under tail-coverts mixed white and yellow; and the white on inner webs of rectrices is lacking. The juvenile male is similar to the adult female except that the ab- dominal stripes are similar to, but not as dark, as in the adult male. We list the isix ‘‘Bogota’’ specimens in the American Museum of Natural History as antioquiae following de Schauensee* and Hellmayr’, but they are intermediate with striolatus. Five have white bases to the pileum feathers while the striping of the under parts is intermediate. They may have come from far different localities, one from the other.

(928); tarsus, 16; Outside of the Perij& specimens we know of only six others of the species superciliaris: two co-type females of the subspecies superciliaris in the British Museum from Chitra and Calovevora, Veragua, Panama, and two from Costa Rica; and of palloris two specimens, the type from Tacarcuna, eastern Panama and a ‘‘ Bogotaé’’ skin in the Paris Museum. Regarding the species, Griscon”® says in his original description of palloris ‘‘One of the rarest and least known of the Tyrant Flycatchers in the world—’’. It was described as of the genus Leptotriccus. Hell- mayr® placed it in Mecocerculus and de Schauensee™ considers it Phyllos- cartes. Apparently there has been a confusion as to the type locality of palloris. Griscom”, in his original description, gives the type locality as ‘‘Tapalisa, E. Panama.’’? de Schauensee”™ also says ‘‘Tapalisa, eastern Panama.’’ The senior author examined the type specimen in the Ameri- can Museum of Natural History. The label says ‘‘Tacarcuna, E. ®Birds of the Americas, 5, p. 400, 1927. 100cc. Papers Boston Soc. Nat. Hist., 8, p. 200, 1935. “The Birds of Colombia. Caldasia, 5, No. 24, p. 852, 1950. 2 Phelps and Phelps, Jr—New Birds from Perija 97 Panama.’’ Dr. Zimmer, in litt., advises us that the type was collected at 5000 feet elevation and that Tapalisa (or Tapaliza) is some ten or twelve miles to the southwest of Tacarcuna at apparently 300 feet eleva- tion. He says that the difference in latitude and longitude is not of significance but that of elevation might be important. The altitude of Tacareuna is subtropical while that of Tapalisa is decidedly tropical. Specimens Examined P. s. palloris.—PANAMA: Tacareuna, eastern Panama (type), 1¢.

Van Dersal called to the ~ writer’s attention the presence of fresh-water jellyfish in a channel of the Potomac River. Several specimens were cap- tured and, although no suitable preservative was at hand, they remained in a sufficiently stable condition to permit iden- tification. Dr. Waldo L. Schmitt of the United States National Museum identified the specimens as Craspedacusta sowerbu. The finding of Craspedacusta constitutes a new record of animal life for the property of the Washington Biologists’ Field Club, and possibly for Maryland. The location is slightly more than a mile above the town of Cabin John, Montgomery County, Maryland, in the channel between the mainland and Plummers Isiand. At the time that the specimens were taken the channel was connected with the river only at the down- stream end. There was little apparent water movement in the channel. Schmitt (American Naturalist, LX XIII, pp. 83-89, January-February 1939) reports the jelly fish from the District of Columbia and from nearby localities in Virginia, but does not ES Maryland among the states in which it has been found. In correspondence Dr. Schmitt suggested to the writer a report on his observation, hence, it seems probable that this is the first actual reported occurrence in Maryland. Bennitt (American Naturalist, LX VI, 287-288, July-August, 1932) cites Schmitt’s record from the Potomae River, and says, ‘‘the hydroid of Craspedacusta has been found in four different states, and the madusa in ten states, the District of Columbia, and the Canal Zone.’’ Only 8 states, however, can be identified in his table. Maryland is not listed. Dexter, Surrarrer, and Davis (Ohio Jour. Sci. XLIX, 235-241, Nov. 1949) list Maryland as a place of record. Dr. Dexter (communication April 6, 1950) believes the Schmitt record from Great Falls may have been interpreted as the Maryland record. Whatever the case, Craspedacusta seems to occur from time to time in the vicinity of Washington, D. C. particularly in the Potomac and reservoirs filled from it.

CAUSEY Fayetteville, Arkansas The inclusion of the family Striariidae in the suborder Chordeumoidea in this paper is a departure from the general practice of regarding it as forming the suborder Striaroidea, on an equal footing with the suborders Chordeumoidea and Lysiopetaloidea (Cook 1896, 1899). The family’s most striking characteristics—the hood-like first tergite, the broad anal ter- gite, and the greatly depressed keels—are adaptations for close coiling that have appeared independently in other groups of millipeds, for example, in the order Oniscomorpha and in the family Oniscodesmidae of the order Polydesmoidea. These characters are therfore not of an essential nature and their presence in the Striariidae does not warrant the establish- ment of a rank as high asa suborder. The labral spines, which Cook believed to be of great taxonomic importance also, have been reduced in value to specific characters since the discovery (Loomis 1936) that in at least one species, and possibly another, the spines are absent. Of greater importance in the Striariidae than any of the characters mentioned above, are the presence of six setae on each tergite, the absence of repug- natorial pores, and the posterior gonopods composed of two articles ; the first two of these essential characters are found in all families of the Chordeumoidea and the last in several families. Their presence in the Striariidae justifies the posi- tion taken here. Any scheme of grouping that separates the Striariidae from the Chordeumoidea will defeat the major purpose of classification, namely, to place together like ob- jects and to separate unlike objects. The holotypes of the new species of Striaria and Conotyla are in the collection of the Illinois Natural History Survey, Urbana, Illinois; and those of Ozarkogona and Caseya are in the United States National Museum, Paratypes are in the author’s collection. 19—PrRoc.

Figs. 1-3 Near S. columbiana Cook 1899 in the details of the gonopods; dis- tinguished from that species by the anteriorly directed labral spines. Male holotype—Color brown; body cylindrical, although the dorsum is somewhat depressed on the first few segments; no setae observed. Head with 4 or 5 ocelli on each side; labrum (Fig. 1) with anterior margin less convex between the medial teeth and the lateral spines than in columbiana; spines directed in front of head, not sharply bent mesiad as in columbiana. Crests coarse and well elevated; surface of metazonites other than crests coarsely granular; prozonites very finely and evenly granular. Collum with 10 crests; segments 2 through 29 each with 12 dorsal and lateral crests; anal segment, which is without crests, terminates in three evenly rounded lobes, the medial of which is slightly longer and wider than the lateral two; the sinuses between the lobes are acute. The usual anteriorly projecting crests near the ventral margin of the meta- zonites begin on segment 4 and continue through 27, becoming smaller caudad. Pregenital legs typical of the eastern species of the genus. No pits were observed on the caudal surface of the coxae of the second legs; instead there was a small rectangular lobe on the sternum adjacent to the surface of each second coxa. Coxites of third legs as long as the third segments of those legs. First and third segments of legs 4 through 7 moderately swollen ventrad; third and fourth segments of seventh legs more swollen. In situ the anterior gonopods are parallel, contiguous, and directed slightly caudad. Each one consists of three pieces (Fig. 2), of which one is lateral and two are medial. The lateral piece is simple, quadrate, shield-like, and shorter than the other two. The anterio-medial piece is the one figured by Cook as ‘‘the apical portion of the copulatory legs;’’ its apex is divided into about 10-finger-like pieces; the shaft has the usual several horizontal striae. A portion of the apex of the posterio-medial Piece is finely pubescent and a stout spine is directed laterad from the apex. The posterior gonopods, the second pair of appendages on the seventh segment, consist of the usual two segments (Fig. 3), with the second one finely pubescent on the ventral surface.

Figs. 4, 5 Similar to the sympatric species C. specus Loomis 1939, from which it can be distinguished by the larger size, fewer ocelli, pectinate processes on the gonopods, and the specialization of the pregenital legs. Nell B. Causey—Four New Chordeumoid Millupeds 113 Male holotype.—Color in preservative horn brown. Ocelli 12 on one side, 13 on the other, in a triangular patch. Antennae as in C. atrolineata Cook and Collins 1895. Gnathochilarium without promentum. Segments with distinct humeral swellings, but there are no projecting keels. Segmental setae short and inconspicuous. Prozonites granular, meta- zonites shining, smooth. _ First legs unspecialized. Coxae of legs 2, 3, and 4 unspecialized; the remainder of those legs lost from the type specimen. Segment 3 of fifth legs with a pyramidal lobe on the distal margin. Segments 3 and 4 of sixth legs with low, cylindrical lobes on the proximal region, the - distal surfaces of the lobes and the coxae finely spinose. Proximal ventral region of segment 3 of seventh legs with a cylindrical lobe. Tenth legs unmodified except for the usual gland opening in the coxae, from which large mucous plugs protrude. Segment 3 of eleventh legs with a pyramidal lobe on the proximal caudal surface; no gland open- ings observed in the coxae. In situ the gonopods resemble those of specus; the ventral branches are simple, longer than in specus, of almost uniform width throughout their length, with the ends slightly expanded and reaching just beyond the coxae of the eleventh legs. The ventral branches are pectinate along their dorsal surfaces (Fig. 4), while the dorsal branches are either very short or they were broken off near the base. The posterior gonopods (Fig. 5), or ninth legs, are typical of the genus. Each one consists of two enlarged segments, with the basal one lobed and finely spinose mesiad. The sternum is lamellate and pectinate as shown in the figure. Width 1.3 mm. Locality. Smith Park, Mt. Carroll, Carroll County, Illinois; 1 male, H. H. Ross and M. W. Sanderson, Dec. 6, 1945. Several specimens of C. specus were in the same collection. Family Caseyidae Caseya similis, n. sp. Figs. 6, 7 Easily distinguished from C. heteropus Cook and Collins 1895 by the attenuated apices of the ventral branches of the anterior gonopods and the details of the coxites of the posterior gonopods. Unfortunately, spe- cific comparisons with C. sequoia Chamberlin 1941 and C. dynotypa Chamberlin 1947, which were described from females and immature males, cannot be made. Male holotype.—Color in aleohol dark brown, each segment with sev- eral light spots. Eyes triangular, ocelli in rows of 6, 6, 5, 4, 2. Stria- tions and locations of setae typical of the genus. Legs as described for heteropus except that the coxae of the sixth have fewer setae. Each anterior gonopod appears to be composed of three longitudinal pieces, with the lateral piece surpassing the others and partly enclosing them ventrad and laterad (Fig. 6). In situ, ventral view, the mesial mar- gins are parallel and almost contiguous for about two-thirds of their length, while the distal one-third is attenuated and directed caudo- laterad. The apices rest on the coxae of the tenth legs. The posterior gonopods, or ninth legs, are similar to those of heteropus 114 Proceedings of the Biological Society of Washington in the large, globular, sparsely setose terminal segment, but they differ in the details of the coxites. The apex of each coxite is bifid; the lateral branch is a thin lamella and the mesial branch is heavier and beak-like, as shown in figure 7. Width 1.7 mm. Locality.—Telachapi Pass, Clear Creek, Kern County, California; 1 male, O. F. Cook, Feb. 15, 1929. Family Cleidogonidae Ozarkogona ladymani, n. sp. Figs. 8, 9 Similar in size, pattern, and coloration to the genotype, O. glebosa Causey 1951; distinguished from that species by the simpler lobes on the basal segment of the posterior gonopods and the less attenuated ventral branches of the anterior gonopods. Male holotype.—Brown above; lateral buff and brown longitudinal bands; buff below; distal half of legs brown. Eyes black, triangular, the ocelli arranged in rows of 1, 7, 6, 5, 4, 2, 1. Tenth and eleventh legs as in glebosa. Each anterior gonopod consists of a dorsal clavate branch, a short, wide lateral piece, and a ventral branch, of which the dorsal margin is very finely serrated (Fig. 8). The ventral branches are separated at their bases, then contiguous at about the middle of their length, then turn obliquely laterad and dorsad; the ends are rounded and flattened vertically. The posterior gonopods, or ninth legs (Fig. 9), are composed of four segments, of which the first is thickened, elongated, and lobate; the telopodite, which is composed of segments 2 through 4, is moderately re- duced. The second segment is characteristically elongated; the third and fourth are shortened, and the terminal claw is short. The lobes on the basal segment, of which there are two on the cephalic surface and one on the medial surface, are in the same relative position as the lobes in glebosa, but those on the cephalic surface are smaller and simpler than in the genotype. The third segment is brown, the fourth, second, and distal one-third of the basal segment and the sternal peg are light brown; cream otherwise. A transverse division of the fourth segment is weakly indicated. In sitw the telopodites are easily visible against the pleurites of the sixth and seventh body segments; the heads of the clavate branches of the anterior gonopods pass between the sternal peg and the medial lobes of the posterior gonopods, and the ends of the ventral branches rest on the caudal surface of the medial lobes.

G. DrIcnNAn* My friend. Arthur de Carle Sowerby has recently brought to my attention that, in 1908 and again in 1909, he collected in the neighborhood of Fushih [Yenan], in northern Shensi, specimens of a ferruginous-cheeked scimitar-babbler very dis- tinct from Pomatorhinus gravivox David of southern Shensi. My examination of skins from the areas in question has con- firmed his statement, but study of the literature of the species has shown such great discrepancy in the several authors’ treatments of these birds, that the new form could be named only subsequently to a thorough revision of all the Chinese populations, which is attempted below. For the loan of valu- able material, without which the study could not have been prosecuted, I am greatly indebted to the authorities of the Museum of Comparative Zodlogy (Cambridge), the Peabody Museum of Natural History (New Haven), the American Mu- seum of Natural History (New York), and the Chicago Nat- ural History Museum. | The taxonomy of this scimitar-babbler has been greatly complicated by the fact that the species breaks into three fairly well differentiated groups of races, one ranging from the western Himalayas to the Shan States and northwestern Thailand (erythrogenys and allies), another restricted to southeastern China and Formosa (erythrocnemis and allies), the third (gravivox and allies) occupying the intervening regions. Since _meclellandi of Assam and western Burma is an individually variable pop- ulation, some members of which approach erythrogenys, while others are more like gravivoz, even the earliest trinomialists did not hesitate to treat gravivoz and erythrogenys as conspecific, but eventually Rothschild (Nov. Zool., vol. 33, 1926, p. 262) was to affirm that the two types were abso- lutely sympatric in central-western and northwestern Yunnan, and Tice- hurst (Ibis, 1935, p. 47) that they were probably so also in northeastern Burma. These writers accordingly accepted the two species ‘‘erythro- genys’’ and ‘‘meclellandi,’’ under the latter name arbitrarily including all Chinese races of gravivox-facies, despite the fact that mcclellandi, whether geographically or by plumage, is obviously more closely related to erythrogenys than to graviwoz. Following Rothschild and Ticehurst’s views, I have vainly attempted to find a single external character by which a given population of the ferruginous-cheeked scimitar-babbler might be assigned to one or the *Published by permission of the Secretary of the Smithsonian Institution. 20—Proc. Brou. Soc. WASH., Vou. 65, 1952 (119) 1952 120 Proceedings of the Biological Socrety of Washington other ‘‘species,’’ yet if their claims of sympatry were well founded, some such character must necessarily be discovered. Critical examina- tion of these claims, however, has shown that they are based upon pre- mises of dubious validity. Rothschild reported that Forrest took two fledglings of ‘‘Pomato- rhinus erythrogenis imberbis Salvad.’’ at Tengyueh and in the Likiang range, at each of which localities he also collected adults of ‘‘ Pomato- rhinus macclellandi odicus.’’ Rothschild was clearly unaware that fledg- lings of members of the gravivoz-group are plain-breasted and for a time inseparable from those of members of the erythrogenys-group, and one of Forrest’s skins (Tengyueh) that now lies before me (A.M.N.H. No. 586216) is in fact almost identical with an equieval topotypical speci- men of odicus. Rothschild’s statement that Anderson likewise took ‘“imberbis’’ at Tengyueh is not confirmed by Anderson’s own comments on the skin that he in fact misidentified as ‘‘erythrogenys’’: ‘‘This specimen agrees in every respect with one from Simla, except that the breast is dashed with dark-brown instead of dusky, of the same intensity as in P. erythrocnemis, Gould, to which it has wonderful resemblance in many ways; but the bright rusty of the knees and vent are not darker than the rusty on the sides of the abdomen and body generally’’ (Ana- tomical and Zoological Researches, comprising the results of the two expeditions to Western Yunnan, 1868 and 1875, p. 634, 1878). The ‘wonderful resemblance’’ to erythrocnemis of Formosa seems to show that Anderson was dealing with an example of odicus, the member of the gravivox-group common at Tengyueh. With reference to eastern Burma, Ticehurst (loc. cit.) has observed: ‘¢. .. so near together as Bhamo [lat. 24°15’ N., long. 97°14’ E.] and Bernardmyo [lat. 23°00’ N., long, 96°30’ E.] odicus and erythrogenys wmberbis are found, the two bearing little resemblance to each other, and no intergrades being known.’’ It must be noted, however, that Bhamo is in the ‘‘distribution area’’ known as ‘‘North-East Burma,’’ while Bernardmyo lies in the one known as ‘‘The Northern Shan States,’’ and numerous plastic species are represented in these diverse areas by dis- tinct races (cf. Garrulax erythrocephalus forresti and G. e. woodi). Sympatry in eastern Burma is, then, an assumption almost certain to be false. Since all forms of ferruginous-cheeked scimitar-babblers from the western Himalayas to Formosa are apparently allopatric, and no char- acters of specific value can be found for separation of the several groups, all may be treated as races of Pomatorhinus erythrogenys Vigors, 1832. I find in China ten recognizable subspecies, of which four are here to be named for the first time. Racial distinctions appear mainly in the general coloration of the upper parts, and since immature specimens show a tawny wash, and worn ones become more grayish, my diagnoses have been based wholly upon fresh-plumaged adults (October-January). 1.

Diagnosis: General coloration of upper parts olivaceous brown, with a rufescent suffusion; front and supraloral region, auriculars, sides of neck and breast, flanks, and under tail coverts vivid ferruginous. Range: Southeastern Yunnan; northwestern Tongking; northern Laos; Southern Shan States (Kengtung State) ; southwestern Yunnan (north to Yunlung at lat. 25°53’ N., long. 99°20’ E.); northeastern Burma (vicin- ity of Htawgaw at lat. 25°57’ N., long. 98°22’ E.). 2. Pomatorhinus erythrogenys decarlei, subsp. nov. Type: U. S. Nat. Mus. No. 312267, adult male, collected at Nguluko (a settlement at elev. 10,000 ft. in the mountains just north of Likiang), northwestern Yunnan, in January-February 1929, by Joseph F. C. Rock (original number 935). Diagnosis: Coloration of upper parts similar to that in odicus, but with less rufescent suffusion, so that the general tone is darker and grayer; front and supraloral region, auriculars, sides of neck and breast, flanks, and under tail coverts of a slightly deeper and considerably less vivid ferruginous. Range: Northwestern Yunnan (Likiang range) ; southeastern Sikang; southwesternmost Szechwan. 3. Pomatorhinus erythrogenys stoneae, subsp. nov. Type: U. S. Nat. Mus. No. 296714, adult male, collected in the moun- tains near Yangtza [ca. lat. 28°15’ N., long. 98°48’ E.], northwesternmost Yunnan, in November 1923, by Joseph F. C. Rock (original number 1441). Diagnosis: From decarlei separable by having the coloration of the upper parts a decidedly darker rufescent-olivaceous brown, and from dedekani by having these parts a distinctly warmer and more rufescent olivaceous brown. Each of five specimens examined also has the pectoral streaks broader than I have found them in any example seen of any other race. Range: Mekong valley between lats. ca. 27°12’ N. and ca. 28°15’ N. Remarks: This form may be found to occur also in northernmost Burma and easternmost Assam, from neither of which areas the species is yet known. It is named in honor of Mrs. Joan Evelyn Stone, née Sowerby. 4, Pomatorhinus erythrogenys dedekeni Oustalet Pomatorhinus Dedekensi [sic] Oustalet, Annales des Sciences Nat- urelles, (Zool.) sér. 7, tome 12, ‘‘1891,’’ p. 276 (‘‘Tioungeu,’’ error; type locality corrected to Tsonghai [lat. 29°56’ N., long. 98°40’ B.], Sikang, by Oustalet, Nouv.

Arch. Mus. [Paris], sér. 3, tome 5, 1893, p. 199). Diagnosis: Near to stoneae, but with the upper parts a colder olivace- 122 Proceedings of the Biological Society of Washington ous brown, more nearly free of rufescent suffusion than any other race, and to decarlei, but with the upper parts both colder and darker. Range: Northeastern Sikang (Kangting [Tatsienlu], Leh [ca. lat. 29°56’ N., long. 98°40’ H.], and Sama [lat. 30°35’ N., long. 99]07’ H.°). Remarks: Immatures of this dark form, possessing the usual reddish suffusion of the upper parts, are much like adults of stoneae. The subspecies was named in honor of Father Dedeken, a Belgian mis- Sionary who accompanied Bonvaiot and Prince Henry of Orléans on the expedition which led to its discovery (see Bonvalot, L’Asie Inconnue / A travers le Tibet, in any edition). Oustalet’s erroneous spelling has been followed by all authors until now, but in justice to the namesake it should be corrected to dedekeni. 5. Pomatorhinus erythrogenys gravivox David Pomatorhinus gravivoz David, Annales des Sciences Naturelles, (Zool.) sér. 5, tome 18, 1873, art. 5, p. 2 (southern Shensi). Diagnosis: General coloration of upper parts nearest that of odicus, but with slightly less rufescent suffusion; front, supereilia, auriculars, sides of neck and breast, flanks, and under tail coverts a much duller ferruginous (along the flanks strongly suffused with olivaceous brown). Range: Kansu and Shensi (so far as these provinces lie south of the Chinling Mountains). Remarks: In this and some of the succeeding races, the supraloral and auricular regions are conjoined by a ferruginous supercilium. 6. Pomatorhinus erythrogenys sowerbyi, subsp. nov. Type: U.S. Nat. Mus. No. 211874, adult male, collected 12 miles south of Fushih [Yenan-fu], northern Shensi, on January 8, 1909, by Arthur de Carle Sowerby. Diagnosis: From P. e. gravivoz (southern Shensi), with which it has been heretofore confused, immediately separable by the decidedly paler rufescent-olivaceous brown of the upper parts generally, and by the paler ferruginous of the front and supercilia. Range: Although known only from the type locality, this form doubtless ranges throughout the loessland between the Ordos (to the’ North) and the Chinling Mountains (to the South). Remarks: A second specimen, taken by Sowerby at the type locality on March 31, 1908, is now in the British Museum (Natural History). That the two skins agree in the characters mentioned above is indicated by the eritical remarks and a water-color drawing made by the collector in his field diaries, which have been made available for my use. The pallor of sowerbyi is what might be expected in the northernmost popu- lation of the species, and in one inhabiting a semiarid terrain. 7. Pomatorhinus erythrogenys cowensae, subsp. nov. ‘Type: Amer. Mus. Nat. Hist. No. 204833, adult female, collected at Wanhsien, eastern Szechwan, on January 6, 1923, by members of the Museum’s ‘‘Third Asiatic Expedition’’ (original number G 411). Diagnosis: From gravivox and all other precedent races easily dis- tinguishable by having the general coloration of the upper parts (inelud- ing the rectrices) rufous brown, darker and redder than in any form H. G. Degnan—Pomatorhinus Erythrogenys Vigors 123 yet mentioned; the front, supercilia, auriculars, sides of neck and breast, flanks, and under tail coverts dark cinnamon (along the flanks strongly suffused with olivaceous brown). Range: Eastern Szechwan, northern Kweichow, and southwestern Hupeh (the Yangtze valley from Wanhsien to Ichang). Remarks: The characters of this form have been remarked by Tice- hurst (Ibis, 1935, p. 47) and by Mayr (Ibis, 1941, p. 67), each of whom, however, assumed that his material represented gravivox. The Kansu bird described by Mayr as ‘‘less brownish than six birds from eastern Szechwan’’ was his only specimen of true gravivou. A single skin from Pingwu [Lungan] (in north-central Szechwan just south of the Kansu border) belongs with a population intergradient be- tween gravivox and cowensae; it might be represented as gravivox > cowensae. The new form is named in honor of Mrs. Alice Muriel Sowerby, née Cowens. 8. Pomatorhinus erythrogenys swinhoei David Pomatorhinus Swinhoei David, Annales des Sciences Naturelles, (Zool.) sér. 5, tome 19, Nos. 3-6, May 5, 1874, art. 9, p. 5 (‘‘Koatén’’ [ea. lat. 27°13’ N., long. 117°12’ E.], Fukien). Diagnosis: This race is readily separable from all yet treated by hav- ing the feathers of the crown rufescent brown with blackish-brown cen- ters; the remaining upper parts red-brown, much brighter on the mantle, where the color is maroon-chestnut; the front and ill-defined supercilia maroon-chestnut; the auriculars between maroon-chestnut and dark cin- namon; the under tail coverts dark cinnamon; the sides of the throat, breast, and abdomen gray (not ferruginous or cinnamon), strongly washed along the flanks with rufescent-olivaceous brown. Range: Eastern Kiangsi; Fukien; Kwangtung. Remarks: This and the two following forms have commonly been con- sidered a species distinct from other ferruginous-cheeked scimitar- babblers (usually with the erroneous specific name swinhoei, 1874, rather than erythrocnemis, 1863!), but I find no reason not to combine them, since cowensae shows a first step toward intergradation between gravivox and swinhoei, and other steps may be expected in hypothetical popula- tions of Kiangsi, Anhwei, and Chekiang. Approach toward swinhoei ap- pears in cowensae in the general reddening of the plumage and the strengthening of the dark centers of the coronal feathers, so that, viewed from above, only the fact that the mantle of cowensae is concolorous with the remaining upper parts serves to distinguish the two. While the gray under parts of swinhoei, washed on the flanks with rufescent-olivaceous brown, are at first glance very different from the white under parts of cowensae, washed on the flanks with dark olivaceous- suffused cinnamon, yet the existence of an intermediate population in Anhwei or western Kiangsi may be postulated by the fact that the northernmost example of swinhoei before me (from Kuatung, near the point where Fukien, Kiangsi, and Chekiang meet) has the flanks washed with rufescent brown, almost without olivaceous suffusion, while more southern specimens have the flanks olivaceous brown, almost without rufescent suffusion. Moreover, the principal color distinction appearing 124 Proceedings of the Biological Society of Washington on the under parts of cowensae and swinhoei is precisely the same as that shown by the nearly related Indian races, ferrugilatus and meclel- landi. It might be well to point out that David’s ‘‘Koatén’’ (sometimes ren- dered as ‘‘ Kaotén’’ or ‘‘Kao-tien,’’ and almost the same place as the modern ‘‘Ting-chia-p’ing’’) is apparently not the same as La Touche’s ‘‘Kuatun’’ (better, ‘‘Kuatung’’). On the sketch map that accom- panies La Touche’s Tandbook of the Birds of Eastern China, ‘‘ Kuatun’’ is plainly marked; ‘‘Koatén’’ is not shown, but lies about nine miles west of ‘‘Shaowu-fu,’’ which does appear. Since my specimen from Kuatung differs in flank coloration from birds of Nanping [Yenping] and southward (which agree with David’s original description of ‘‘ Koa- tén’’ birds), it is important that the two localities be not confused. 9. Pomatorhinus erythrogenys abbreviatus Stresemann Pomatorhinus swinhoei abbreviatus Stresemann, Journ. fiir Orn., jahrg. 77, hft. 2, Apr. 29, 1929, p. 333 (Yao-shan, Kwangsi). Diagnosis: According to the describer, this race, founded upon a sin- gle female, compared with 11 specimens of swinhoei from Kwangtung, differs from swinhoei by shorter bill and wing; by having the throat and upper breast washed with pale rusty (not pure white); the gray of the under parts darker; the under tail coverts dark ferruginous brown (not dark cinnamon). Range: Kwangsi. Remarks: The type, taken on June 20, is doubtless a worn bird, which fact may have some connection with its coloration, and its sex could account for its small size. There is, nevertheless, a strong likelihood that the population of Kwangsi is distinct from that of Fukien. 10. Pomatorhinus erythrogenys erythrocnemis Gould Pomatorhinus erythrocnemis Guold, Proce. Zool. Soe. London, for 1862, pt. 3, Feb. 1863, p. 281 (Formosa). Diagnosis: This form has the feathers of the crown with more nearly black centers and deeper rufescent-brown edges than swinhoei, so that this area is generally darker; the remaining upper parts as in swinhoei, but with the mantle chestnut-brown (not bright maroon-chestnut) ; the front, supraloral region, anterior auriculars, and under tail coverts maroon-chestnut; the posterior auriculars, sides of throat and breast, and flanks deep rufescent brown. Range: Formosa. H. G.

STANNARD, JR. Illinois Natural History Survey Urbana, Illinois Through the kindness of Dr. Wiliam L. Brown, Jr., of the Museum of Comparative Zoology, I have had an opportunity to study a number of interesting Australian thrips. One of these thrips, Amphibolothrips (Verrucothrips) caenosa de- seribed herein, is apparently the second known specimen of the group formerly assigned to the family Urothripidae to be discovered in that continent. The other ‘‘urothripid’’ speci- men is the unique type species of Octurothrips Priesner. Both are from Victoria. According to Doctor Brown these two entities probably came from different ecological areas. Healesville, the type locality of Amphibolo- thrips (Octurothrips) pulcher, generally is more constantly moist through- out the year than is the Victoria Valley, the type locality of caenosa. Although it is not known whether pulcher was found at the base of the Victorian Alps or higher on the slopes that border Healesville, it is possible that both species are subject to similar temperature conditions, cool in the winter and extremely hot in the summer. Most likely the dissimilar rainfall distribution in the two localities is responsible pri- marily for the difference in their habitats. Amphibolothrips Buffa 1909 Almost at the same time that Amphibolothrips and Bebelothrips were described by Buffa, Bagnall brought forth his genus Urothrips. To Bagnall these genera seemed so different from the other Tubulifera that he erected the family Urothripidae for them. Eventually this family was placed in a suborder of its own, Polystigmata. The group had hardly reached such high standing before its rank slowly began to fall. In 1915 it was reduced to a superfamily, the Urothripoidea. Meanwhile and since then, six more genera were proposed: Stephanothrips Trybom 1912, Bradythrips Hood and Williams 1925, Trachythrips Hood 1929, Octurothrips Priesner 1931, Conocephalothrips Bianchi 1946, and Baeno- thrips J. C. Crawford 1948. Finally in 1949 Priesner relegated Uro- thripoidea to Urothripinae as a subfamily of Phlaeothripidae. I prefer to de-emphasize the taxonomic category of these aforementioned genera still further and make them all subgenera of the genus Amphibolothrips. As such the genus Amphibolothrips would be at the apex of the phyletic line that contains as more primitive members Hoodiana, Arcyothrips, 21—Proc, Brow. Soc. WAsH., Vol. 65, 1952 (127) wes 1952 128 Proceedings of the Biological Society of Washington Strepterothrips, Stegothrips, and Idiothrips. If desirable the genera of this plyletic line could be grouped as a tribe of the family Phlaeothripi- dae. Diagnostic characteristics of Amphibolothrips: Head—eyes small, anteriorly placed; antenna four- to eight-seg- mented, with the fusion of the segments occurring between segments III, IV, and V and/or between segments VII and VIII; postocular setae minute; prominent anterior, dilated setae absent or present by one to three pairs. Mouth parts—Mouth cones broadly rounded; maxillary stylets (laciniae) slender extended far into the head when at rest. Thorax—always apterous; praepectal plates large to rudimentary to absent; mesopraesternum usually, possibly always, reduced in size; prothoracic epimeral sutures incomplete; suture between meso- and metasternum usually absent; hind coxa slightly more distant from each other than the middle pair are from each other; all tarsi usually, possibly always, one-segmented. Abdomen—segment I without a differentiated notal shield, the entire notum uniformly sclerotized; segment IX much longer than segment VIII; prominent anal setae four or six in number, each seta three or four times as long as tube. These warty, brown and yellow thrips have been found in the warmer parts of all of the faunal regions except the Oriental region. The placement of the hind coxae, the reduction of all. tarsal segments to one, and the lack of a differentiated notal shield on abdominal seg- ment I are unique characteristics in the Tubulifera. Hoodiana approaches Amphibolothrips in respect to the hind coxae, in that, according to Faure 1933, the hind coxae of Hoodiana are as close to each other as are the middle coxae. northern boundary between the republics of Venezuela and Colombia we have four specimens of a hummingbird that rep- resent an interesting link between Coeligena eos (Gould) of the Sierra de Mérida in northwestern Venezuela and C. bona- partet (Boissonneau) of the western slope of the eastern Andes in the Bogota region of Colombia. The form in ques- tion, which is new to science, may be known as Coeligena bonapartei consita subsp. nov. Characters.—Similar to Coeligena bonapartei eos (Gould!) but with brown spot on secondaries slightly smaller; tail green throughout in- stead of partly hazel; chin and throat much less spotted with iridescent green; lower breast and side more extensively green, and under tail coverts spotted with iridescent green. Description.—Type, Phelps coll. no. 54415, (on deposit in the U. S. National Museum), female, southeastern base of Cerro Tetari, at 2900 meters elevation, Sierra de Perijé, Zulia, Venezuela, taken April 21, 1952 by R. Urbano. Crown and hindneck iridescent cerro green; upper back and lesser, middle and primary wing ecoverts irridescent oil green; lower back somewhat lighter, with bronze reflections that merge with with the iridescent reddish bronze of the rump and upper tail coverts; secondaries cinnamon, tipped slightly with fuscous; primaries fuscous, the outer one edged lightly with yellow ocher; rectrices bronze green, the outer one on each side tipped and edged on outer web with vina- eeous buff; chin, throat and side of head below lores from center of eye to base of mandible cinnamon buff, with small, scattered spots of iri- descent oil green along lateral and posterior borders; foreneck, sides of neck and upper breast iridescent oil green, the feathers dull whitish basally; lower breast, sides and flanks lighter iridescent green with bronzy reflections; abdomen and under tail coverts cinnamon-buff, the latter iridescent green centrally; edge of wing pinkish cinnamon; outer under wing coverts shining oil green; inner under wing coverts and axillars cinnamon. Bill black; lower tarsus and toes fuscous.

Remarks.—This hitherto unknown form is described from three specimens in the Phelps collection taken by R. Urbano March 31, April 2, and April 21, 1952 on the Cerro Tetari on the Venezuelian side of the Perij4 range, and one from the western slope in Colombia, near the base of the southern Teta above Hiroca, collected by M. A. Carriker, Jr., May 4, 1942. All are females, the male being as yet un- known. The following discussion of forms therefor concerns females only. In the diagnosis comparison has been made solely with Coeligena bonapartei eos as the form most closely related. From Coeligena bona- partei bonapartei (Boissonneau) the new race differs in having the sec- ondaries brown forming a distinct spot; the crown and back slightly lighter, more bronzy green; the throat and under tail coverts paler brown; and the abdomen slightly less iridescent green. The three birds under discussion are strikingly similar in general appearance, and in the total sum of their characters evidently are closely related and of the same general stock. The general structure in the three is identical, as is the size. The light brown secondaries that form a prominent mark on the wings of eos and consita seem at first glance to be a prominent difference in pat- tern that might set these two apart as a distinct species. On careful examination of the series of bonapartei at hand we find that while most have the secondaries fuscous like the primaries occasional specimens show a slight mixture of brown in the concealed portion of the second- ary feathers, indicating a slight intergradation in this character. These are trade skins so that the locality is not known, but it appears that they must be considered sufficient approach to the other two to warrant placing all three under the same specific name. The collection of males of C. b. consita will be awaited with interest. We may hope also sometime for material from the Cordillera Oriental, and from the southern Sierra de Perija in the region controlled by groups of Motilone Indians, who at present do not permit strangers to enter, that will demonstrate more clearly intergradation with bonapartet.

It is apparently confined to the island of Hispaniola (Haiti), though other members of its genus are responsible for the same type of damage to the fruit of the banana in other areas. Should it merit a common name, Haiti Banana Thrips is suggested. Frankliniella musaeperda sp. nov. (Fig. 1). Female (macropterous).—Length about 1.3 mm. (distended, 1.6 mm.). Color pale yellow, head whitish, body without dark markings, internal pigmentation yellow, ocellar pigmentation deep red; legs somewhat paler than body; antennz with segments I-III nearly colorless, II with orange pigmentation across tip, IV nearly colorless in about basal half, lightly shaded beyond, V paler than IV because shaded only at apex, VI-VIII yellowish gray; fore wings uniform pale yellowish; sete yellowish gray, those en the two apical abdominal segments and the large dorsal pair on segments II and III of antenne darkest. Head about as long as its width across base and about 0.84 as long as width across eyes, the width at anterior fourth of cheeks somewhat less; cheeks convex, rounded to eyes and to base, without postocular angulation and with only a slight tooth at the faint occipital line; dorsum with pale, faint, widely-spaced cross-stri# in the area posterior to eyes, these producing a faint serration in posterior half, or less, of cheeks; interocellar sete long (64 u), arising just outside line connecting centers of median and posterior ocelli; postocular sete much shorter (40 ») and about 125 uw apart; minor sete minute and nearly colorless, disposed as usual in the genus. Hyes (80 uw) half as long as width of head across them. Ocelli 16-17 mw in diameter, the posterior ones about 36 w apart and about 20 w from median ocellus.

HAITI: L’Arcahail, May 26, 1933, James Zetek, 6 99 and 3 64 (including allotype), from young banana fruit [Hood No. 1069]. Very close to F. cubensis Hood, but somewhat larger, with the third antennal segment longer and more slender (compare Figs. 1 and 2), and the cephalic and pronotal sete longer. The following notes are from my number 1069, and were made in 1933: ‘‘Mr. Zetek brought from Haiti young banana fruits, and I ex- amined them at Barro Colorado Island in June, 1933. They were covered with small dark pustules, perhaps 1/16 of an inch in diameter and half that high, made, I thought, by feeding punctures. Zetek says, however, that Mr. Johnson, of the United Fruit Company, states that they are Oviposition punctures around which the tissues have proliferated, proba- bly in response to the egg within. Johnson says, according to Zetek, that he has reared thrips from eggs which he was able to find in the pustules. The injury renders the fruit unmarketable. The same injury is caused on Barro Colorado Island, Canal Zone, Panama, by another species of Frankliniella.’’ Frankliniella cubensis Hood (Fig. 2). 1925. Frankliniella cubensis Hood, Bull. Brook.

III By J. DoucLAs Hoop ~ The two preceding papers in this series appeared in“Reasta de Entomologia (Rio de Janeiro), vols. 20 (1949) and 21 (1950), and were illustrated with a total of 137 figures. That journal, unfortunately, has had to suspend publication. For the present paper, a similarly exhaustive treatment was planned, a proportionately large number of illustrations were prepared, and the initial descriptions of the new genera and species were fully detailed. But present conditions have forced our journals to publish only brief, non-illustrated contribu- tions unless the author himself defrays the increased costs. Hence, rather than sacrifice the results of much collecting done by myself and others in Brazil—financed in part by Cornell University through grants by the Trustee-Faculty Committee on Research and by a Traveling Fellowship from the College of Agriculture—it has seemed best to solve the problem of publication as I have on similar past occasions: by abbreviat- ing the descriptions and omitting the illustrations. To con- form to the title used in parts I and II of this study, the geo- graphic adjective is spelled with an S, although throughout the text the name of the country is given as Brazil, as in cur- rent practice. 1.

SMICROTHRIPS gen. nov.* Closely allied to Preeriella and Hyidiothrips; antenne 7-segmented, as in the latter genus, but with segments III and IV separate as in the former one, the reduction in number brought about by the union of the morphological sixth and seventh; postocellar sete minute, postoculars large; prothorax with only three pairs of major sete (exclusive of coxals), the antero-marginals and midlaterals** very minute.

Antennal segments *Smikros = mikros, little or small; thrips, a wood-worm—in allusion to the extremely minute size of the type species. **This nomenclature of the prothoracic setz is open to question. In Preeriella the two anterior pairs lie close together near the fore margin of the pronotum, and the outer pair are almost certainly the antero-angulars and the inner the antero-marginals; and this primitive condition is reflected in the presence of eight segments in the antennw. In Hyidiothrips, which is apparently more specialized and which has only seven antennal segments, the inner pair, which would appear to be the antero-marginals, have seemingly become shifted almost into the mid- lateral position. In Smicrothrips one of these two pairs is either missing or eerie. This is presumably the antero-marginal pair, but the homologies are obscure. 174 Proceedings of the Biological Society of Washington (gw) 22015 C17), TE 2419); TR aL (1G), BV. 23; (22), Voto 1 ae 31°C14), Vik 14 <6).

Chinobius sachalinus Verhoeff Chinobius sachalinus Verhoeff, 1937, Arch. Nat. Leipzig, vol. 6, p. 224. Localities: Sendai, Japan. One male and one female taken Sept. 13, 1928, by Z. Ohizumi. Sachalin, Japan. Three males and five females, topotypes, were taken in Sept., 1933, by Takakuwa. Chinobius would seem to be related to the North American Arebius rather than to Paobius. These three genera agree in having the articles of the antennae fixed at 20, in having none of the dorsal plates with posterior corners produced, the anterior tarsi biarticulate, and the pro- sternal teeth normally 2+-2, rarely 3+3. It seems justifiable to keep Chinobius apart from Arebius, as well as Paobius, in having both the penult and the anal legs of the male enlarged or crassate and otherwise secondarily modified in the male while lacking any such modifications in the two latter genera. The genus, as in Arebius, has the legs between the first and the twelfth pairs, with two dorsal tibial spines, with one always present on the penult legs. The head has marginal interruptions and the claw of the female genital forceps is always entire. It differs 182 Proceedings of the Biological Society of Washington from Arebius in having none of the posterior coxae laterally armed, as far as at present known. Chinobius chekianus new species Pale chestnut to dark chestnut, usually with a median longitudinal dorsal stripe. Antennae composed of 20 articles, relatively long. Ocelle in three series; e.g., 1+3, 3, 2. Prosternal teeth 2 + 2; the median sinus u-shaped. Ventral spines of first legs, 0,0,2,1,1; dorsal, 0,0,2,2,2.

In addition to the species listed below, a second Japanese species, Z. crassidentatus (Takakuwa), described in Acta Arachn., 1949, p. 59, clearly pertains to this genus of which an Alaskan species, Z. nothus Chamberlin is the generotype. The two Japanese species show a tendency for the posterior angles of tergites 6 and 7 to be more or less produced in addition to those of plates 9, 11, and 13. The variability of this feature, however, is such that it is improbable that it can be maintained by itself as the basis for subgeneric distinction.

Macrocarpaea 1, Macrocarpaea cerronis Hwan, U. S. Nat. Herb. Contr. 29:223. pl. 2. 1948. It was with considerable hesitancy that I described two species of Macrocarpaea, M. cerronis and M. salicifolia, as distinct from geograph- ically adjacent tepuis of Venezuela on the basis of single collections in each instance. These two species displayed several critical morphological characters in common, as will be easily seen from a study of the facing illustrations in my account. I concluded these two collections repre- sented distinct species not only on the basis of their differences indicated in the species key (p. 216) but because they evidently occupied differ- ent altitudinal positions on these respective cerros. Additional collections may change these interpretations but it is of interest that the second collection of M. cerronis, just made available to me for study, supports my conclusions as to both the distinct morphology of the species and its zonal position. A collection made by Captain Felix Cardona P. (no. 2679), Jan. 1949, on ‘‘cumbre del Cerro Auyan, altura 2,500 mts.,’’ State of Bolivar (US) is a good match for the type, though the corolla in the latest collection is larger (4.5 em. long) and the calyx lobes are longer (9-10 mm. long). 2. Macrocarpaea glaziovii subsp. constricta (Griseb.) Ewan, comb. nov. Lisyanthus obtusifolius var. constrictus Griseb. Gen. et Sp. Gent. 175. 1839. Type: Langsdorf s. n., ‘‘prov.

In the course of my recent report on Macrocarpaea glaziovit,? I dis- tinguished that species from M. obtusifolia of Brazil. There is at Copen- hagen, in addition to the type of M. glaziovii, a second Glaziou collec- tion (no. 900) without locality data, which was mistakenly identified in 1896 by E. Gilg as Macrocarpaea obtusifolia. The calyces are not pubes- cent, however, as in that species, and though the corollas are rather S. Nat. Herb. 29:203-251. 5 pls. 1948. Tolm Soc. Wash. 64:134. 1951.

The locality for this Copenhagen sheet was ascertained by reference to A. F. M. Glaziou’s ‘‘Liste des plantes du Bresil central recueillies en 1861-1895’? (Mem. Bot. Soe. France 3:474 (accompanying Bull. ser. 4, vol. 10 or whole no. vol. 57) 1910). 3. Macrocarpaea valerit Standl. The first historical collection of this Costa Rican species was filed as ‘“Chelonanthus acutangulus,’’ as originally identified by Standley nearly thirty years ago: La Palma, 8 July 1923, F. L. Stevens 279 (US). Dr. W. W. Diehl has kindly examined for me the map accompanying Stevens and Tehon’s paper on Costa Rica and Panama fungi® and La Palma is shown thereon at a point about midway between Puntarenas and Limon and approximately 15 kilometers northeast of San Jose. From this in- formation it appears that both Macrocarpaea valerit and M. subcaudata occur about La Palma, but there is no present reason to doubt the dis- tinctness of M. subcaudata, judging from the two sheets of Werckle’s collection examined. Symbolanthus 4. Symbolanthus gaultherioides sp. nov. Shrub about 1 m. high; upper stems squarish, the internodes short throughout, articulated and rather prominently ridged in drying, thinly black-dingy pubescent with short blackish hairs; leaves small, closely overlapping in the manner of many ericads, rather fleshy when fresh, drying to leave a distinct white cartilaginous edge, oval to shortly ovate, subtruncate at the base, 25-32 cm. long, 17-20 mm. wide, barely acute, very sparsely pubescent with gray or whitish hairs beneath especially along the midrib; flowers borne terminally at ends of the leafy shoots, 56-70 (or 75) mm. long, calyx eylindrical, glabrous or lightly viscid- pubescent, 18-20 mm. long, a little constricted at the mouth, the three outer lobes a little rounded at apices, 12-14 mm. long, the two alternate inner lobes strictly acute; corolla red, the tube slender, cylindrical, 17-19 mm. long, the lobes broadly ovate or oblong-ovate, shortly cuspi- date, finely erosulate, venulose, the lower lobes evidently not strongly dejected or reflexed; fruit unknown. Frutex ca. 1 m. altus; ramis subtetragonis, internodis brevis, sparse atro-pubescentibus; foliis parvis, ericoideis, subcarnosis, ultime distincte albomarginatem, ovalis vel brevi-ovatis, subtruncatis ad basim, 25-32 em. longis, 17-20 mm. latis, vix acutis, infra sparse ecano-puberulentis; floribus terminalibus ad apicem ramis foliosis, 56-70 (vel 75) mm. longis, calyx cylindricis, glabris vel aliquantum viscido-pubescentis, 18-20 mm. longis, ad faucem subconstrictis, 12-14 mm. longis, 3 lobis subrotundatis sed 2 lobis alternatis valde acutis; corolla rubra, cylindricis, 17-19 mm. longis, lobis late ovatis vel oblongo-ovatis, minute erosulatis, breve cuspidatis, venulosis, omnibus lobis horizontalibus vel suberectis; fructus ignotus.

Symbolanthus gaultherioides is closely allied to S. microphyllus Gilg of Peru (ef. Field Museum photo 10236 of type formerly in Berlin Herb.). Both species belong to the alliance of Symbolanthus pauciflorus Gilg, but S. gaultherioides and S. microphyllus are more closely related to each other than S. paucifiorus is to either of the latter species. This is an interesting example of the distribution phenomenon known to the phytogeographer as Jordan’s Rule of Geminate Species: the nearest relative of a given species is not found in the immediate region, in this instance Peru, but at some distance from it. From the habital stand- point these three species of Symbolanthus present the tempting sugges- tion that the genus Calolisianthus may be related to the shrub genus Symbolanthus through this group. The small flower size (for Symbolan- thus) and the position of the flowers which are borne among the termi- nal leaves of the branchlets further support this suggestion. 5.

Grisebach adds the phrase ‘‘a. 1836’? after the citation of collector but though this might be con- strued as a collection number I am inclined to interpret it as ‘‘A(gust) 1836.’’ Though Weberbauer* does not account for Andrew Mathews’s collections for the year 1836 specifically, beyond a general reference to his serious illness during this period, it is known that he botanized about Chachapoyos both before and after that date. The duplicate type in the Delessert Herbarium (ef. Field Museum photo 26837) carries a ticket ‘‘No. 1316,’’ and this may actually represent Mathews’s col- lection number. This is a showy species of Symbolanthus and may represent what Gilg® proposed as Symbolanthus obscure-rosaceus, based on Weberbauer 4634 from the mountains north of Moyobamba, Dept. Loreto, Peru, but this and other details must await the opportunity to study a larger series of collections than I have seen. 6. Symbolanthus stuebelii Gilg This species was described from the Llanos de San Martin, Meta, Colombia, where it was collected by the geographer A. Steubel in August, 1868. It is evidently a rare transandean species, showing again the high endemism of the Colombian flora, and I have seen only a single subse- quent collection: Quetame, Dept. Cundinamarca, July, 1916, M. T. Dawe 322 (US). Though in different political provinces of Colombia these two localities are in the same vegetation type, namely, the wood- lands along the margins of the llanos. 7. Symbolanthus superbus Miers This Colombian species was described from the valley of the Rio “El Mundo Vegetal de los Andes Peruanos 9-10. 1945. 5Fedde, Rep. Nov.

The distribution of Symbolanthus superbus falls into a pattern noticed for Colombian Scrophulariaceae by the late Dr. F. W. Pennell, namely that species of the Magdalena Valley reappear about the head- waters of the Amazon in small localized areas along watercourses. Jour.

PARKES Laboratory of Ornithology, Cornell University, Ithaca, N. Y. Noble demonstrated (Bull. Mus. Comp. Zool., 60, 1916 :367) that the Laughing Gulls (Larus atricilla) of the West Indies were substantially smaller in size than those of the North American continent. From the synonymy of the species he selected for the continental population the name Africilla megalopterus Bruch (Journ. fiir Orn. 3, 1855 :287). Bruch’s type specimen was said to have come from Peru, where the Laughing Gull is an uncommon species, appearing only under certain conditions of water temperature based on movements of the coastwise currents (Murphy, Oceanic Birds of South America, 1936 :1072-1073). A Laughing Gull taken in Peru could have derived from either the continental or the Antil- lean population. Since there are a number of inconsistencies in Bruch’s original description, it was felt that a reexamina- tion of the type of Atricilla megalopterus was imperative. Un- fortunately the identity of this specimen can never be settled. I was informed by Drs. Erwin Stresemann (letter of October 27, 1951) and Joachim Steinbacher (letter of November 20, 1951) that the entire bird collection of the museum at Mainz, including all of Bruch’s types, was destroyed by an air raid on February 27, 1945. It thus becomes necessary to fall back on the principle of the first reviser and assume that Noble cor- rectly fixed Bruch’s name upon the continental population of the Laughing Gull. Of the authors who have written of Larus atricilla since the appearance of Noble’s paper, only Oberholser (La. Dept. Conserv. Bull. 28, 1938: 286) has supported the proposed subspecific division. Recognition of megalopterus was refused by Ridgway (U. S. Nat. Mus. Bull. 50, part VIII, 1919: 636, 641), Dwight (Bull. Am. Mus. Nat. Hist., 52, 1925: 266-267), Wetmore (Sci. Surv. Porto Rico and Virgin Is., 9, 1927: 378- 379), Peters (Birds of the World, 2, 1934: 321), and Hellmayr and Conover (Field Mus. Nat. Hist. Zool. Ser. 13, part 1, No. 3, 1948: 275). None of these authors presented tables of comparative measurements to support their views. Wetmore and Swales (U. S. Nat. Mus. Bull. 155, 1931: 174) showed that wing measurements of West Indian specimens fell into two groups, with ranges of 293 to 305 mm. and 312 to 331 mm. respectively. Nevertheless these authors felt that ‘‘there is however no 28—Proo. Brow. Soc. WASH., VoL. 65, 1952 193 NOY 3 Wedd ton ing ty of Wash ogical Socie 7 uv 10 194 Proceedings of the B TIVINANTLNOO I I |!

For the present study, all of the Laughing Gulls in the collections of the American Museum of Natural History, the Chicago Natural History Museum, the United States National Museum, and Cornell University were examined. Measurements were made of adult birds in breeding plumage taken during the breeding season. It became apparent early in the study that there is a significant sexual difference in size in this species. Because of time limitations, attention was focussed thereafter on males. My measurements coincide remarkably well with those of Noble, whose 22 specimens did not include any of those I measured. The most significant measurements, in decreasing order of importance, were found to be those of the flattened wing, tarsus and tail. Fre- quency distributions of the combined measurements are given on the accompanying table, and show graphically the difference in size between these two populations. Although there is some overlap, an individual specimen is seldom intermediate in all measurements. Thus, the indi- vidual with the longest wing among the Antillean specimens examined measured 328 mm., which is within the limits of the continental race. However, this individual had a tarsus measuring only 44 mm., smaller than the smallest mainland bird but about average for the West Indian population. In view of the measurement differences shown in the table, I am of the opinion that Noble and Oberholser were justified in their recognition of two subspecies of the Laughing Gull. For the reasons given in the first paragraph of this paper, the names of the two subspecies will stand as follows: Larus atricilla atricilla Linnaeus, Syst. Nat., 10th ed., 1, 1758: 136 (Bahama Islands). Antillean Laughing Gull. Larus atricilla megalopterus (Bruch). From Atricilla megalopterus Bruch, Journ. fiir Orn., 3, 1855: 287 (Peru).

JoHNSON United States National Museum The name Molossus fuliginosus W. Cooper (Ann. New York Lyceum Nat. Hist., vol. 4, p. 67; November, 1837), which was applied to a bat from Milledegeville, Georgia, of the species currently known as Tadarida cynocephala (Le Conte), invali- dates the name Molossus fuliginosus proposed by Gray in Feb- ruary, 1838, for a different kind of bat from Jamaica. This fact was recognized in 1914 by G. M. Allen, who considered the Jamaican bat to be identical with the Hispaniolan Molos- sus verrilli of J. A. Allen (Bull. Amer. Mus. Nat. Hist., vol. 24, p. 581; September 11, 1908), hence not in need of a valid name. In 1913, however, Miller had published a revision of the genus Molossus in which he recognized differences between the type of verrilli and the thirteen specimens from Jamaica then in the U. S. National Museum collection. Apparently overlooking the fact that Gray’s name was preoccupied, Miller continued to use it for the Jamaican form, and subsequent authors have followed his example. A new name is here provided as a substitute for Molossus fuliginosus Gray, with a list of the principal technical citations that apply to the older name. Molossus milleri, new name 1838.

Molossus milleri is intended to be wholly synonymous with Gray’s Molossus fuliginosus, taking the same type specimen and type locality. The Jamaican specimen designated lectotype by Dobson is presumably still in the British Museum. The new name is suggested in honor of Gerrit S. Miller, Jr., former Curator of Mammals in the United States National Museum, the author of ‘‘The Families and Genera of Bats,’’ and the latest reviser of the genus Molossus. In using a binomial rather than a trinomial form I am aware that, when viewed by present concepts of the relative values of species and subspecies, many of the kinds of Molossus are more closely related than Miller’s revision of nearly forty years ago would indicate. The next re- viser of the genus may treat many of Miller’s Antillean ‘‘species’’ as geographic races of a few widely ranging species. Until a revision based on study of specimens has been completed, however, it is surely bad taxonomic procedure to attempt to anticipate its conclusions.

I take pleasure in naming it in honor of the late Charles J. Hubbard, former Chief of the Arctic Section, U. S. Weather Bureau, whose whole-hearted cooperation and interest made possible extensive biological studies and collections in Arctic America. For the loan of comparative material I am grateful to the National Museum of Canada. Lepus arcticus hubbardi, subsp. nov. Type.—U. S. National Museum No. 290933; adult male, skin and skull; collected 11 June 1949, by Charles O. Handley, Jr., at 350 feet elevation, near Cherie Bay, 5 miles NE of Mould Bay Station, Prince Patrick Island, District of Franklin, Northwest Territories, Canada (76° 20’ N. lat., 119° 08’ W. long.); collector’s No. 1283. Distribution.—Known only from Prince Patrick Island, Northwest Territories, Canada; probably inhabits other islands to the east and northeast. Zonal range, Arctic. Description—Adult summer pelage: Predominantly white in most specimens; tip of ear black; posterior inner and anterior outer sur- faces of ear pinkish-buff, remainder of inner and outer surfaces and narrow subterminal band white; nose, cheeks, and top of head pale pinkish-buff; other parts of body, feet, legs, and tail pure white, or with a sprinkling of gray guard hairs on upper back, sides, and throat. Adult winter pelage: Entirely white, except for black on tips of ears. Juvenal summer pelage: Top of head and ears yellowish-brown; ears black-tipped; remainder of body, legs, and feet pale pinkish-gray, lighter than head and ears; tail white. Size large; tail long. Skull large; pre- maxillae greatly elongated; first upper incisors long and with a large radius of curvature; nasals long and wide; maxillary molars large and tooth row long.

Comparisons.—Lepus arcticus hubbardi is the largest and most prog- nathous of all the Eastern American Arctic hares. It is closely related to L. a. monstrabilis, which it resembles in most respects. However, hubbardi averages less white in summer pelage, it is larger and longer- tailed, its skull averages slightly larger in all dimensions (but dis- proportionately larger in nasals and molars), and its incisors have a greater radius of curvature. The first upper incisor of hubbardi forms the are of a eircle the radius of which averages 21.6 mm.; the corre- sponding measurement for monstrabilis is 19.3 mm. The new subspecies is quite different from L. a. andersoni, which, though heavier in body and skull, is smaller in most linear dimensions, is much less prognathous (radius of curvature of upper incisor 13.9 mm.), and is dark gray rather than white or whitish in summer pelage.

EMERSON?’ Museum of Paleontology University of California A number of nomenclatural problems were encountered by the writer during the preparation of a manuscript pertaining to the type species of the genera and subgenera which com- prise the molluscan class Scaphopoda. The purpose of this paper is to outline the nomenclatural history and indicate the genotype species of the ‘‘subgenera,’’ Mustiaria and Pseu- dantalis. FUSTIARIA Stoliezka, 1868 Stoliczka (1868:439) proposed Fustiaria, without designating a type species, for Dentalium eburneum Lamarck (1818:346), D. circinatum Sowerby (1823:f.5), and ‘‘others figured by Sowerby [1823] in his ‘Genera of Shells,’ by Deshayes [71864] in his last edition of the ‘ Paris Fossils’.’’ He provided the following description, ‘‘shell tubular, thin, usuaily slightly curved, smooth, posterior end with a long, linear slit on or near the ventral side.’’ Stoliezka appears to have intended this group to include all species possessing a long, straight cleft on the convex face. However, with the exception of his citation of Sowerby and Deshayes’ figures of D. circinatum and D. eburneum, no reference was made to forms possessing encircling grooves which divide the surface into many narrow segments. Since such an annular striate species, D. circinatum Sowerby (here illustrated pl. IX, fig. 1) was contained in the original list of species, Cossmann (1888:9) and subsequent writers have justi- fiably expanded the original concept of the group to include both smooth and annulated species which have the long linear mid-convex slit. The designation of ‘‘ Dentalium eburneum Linnaeus, Systema Naturae, 1767’? by Newton and Harris (1894:64) appears to be the earliest genotype designation. It should be noted that Stoliczka (1868:439) credited D. eburneum to Lamarck, not Linné; Lamarck (1818:346) in turn listed in the synonomy of his D. eburneum a reference to Linné (1767:1264) and considered his D. eburneum identical with the Linnaean species. Most subsequent writers, including Pilsbry and Sharp (1897: 116), have followed this interpretation. On the basis of the foregoing, this designation apparently should be considered as being valid.

WasH., Vou. 65, 1952 201 > v WOV 6- 1952 LIBRARY NOV > 6185? 202 Proceedings of the Biological Society of Washington ever, Dr. N. H. Ludbrook® kindly informed the writer that Favre (1912: 346) found Lamarck’s specimens of ‘‘D. eburneum’’ contained in the Museum d’Histoire Naturelle de Genéve to be actually the Grignon Eocene fossil, D. subeburneum d’Orbigny (1850:372), here illustrated pl. IX, fig. 4. Dr. Ludbrook personally examined this material and sub- stantiated Favre’s earlier findings. The validity of the designation thus becomes open to question. It should be noted that under the Régles in effect prior to 1951, Opinions 65 and 168 might be interpreted as vali- dating the above designation, and this situation is apparently similarly covered in the revised Régles,‘ which unfortunately are not at the time of this writing in print. The acceptance of Dentalium eburneum as the type species would be an unfortunate choice as considerable confusion exists concerning the true identity of this species and would necessitate changing the current concept of the subgenus. An examination by Hanley (1855) of the Lin- naean collection deposited in the Linnaean Society of London disclosed that the holotype is Recent and that the fossil ‘‘D. eburneum’’ speci- mens of most nineteenth century authors writing before 1855 are re- ferable to Dentalium politum Linné (1767:1264) from the Eocene of the Paris Basin.* On the basis of Stoliczka’s citation of figures, his reference to ‘‘Dentalium eburneum, Lamck.’’ undoubtedly refers to a fossil, either D. politum Linné, 1767, or more probably D. subeburneum d’Orbigny (1850:372) from the Paris Basin Eocene. Nevertheless, D. eburneum Linné (1767:1264) here illustrated, pl. IX, fig. 6, is a Recent species which has numerous, unequal, irregularly spaced, annular wrinkles, and Jacks the long, linear slit which characterizes the fossil species, e.g. D. lucidum Lamarck, 1818 and D. circinatum Sowerby, 1823, here illustrated, pl. IX, figs. 1, 5. If the type designation of Newton and Harris (1894:64) is accepted as the earliest valid designation, a new subgeneric name would have to be proposed for the Fustiaria group of authors. Under this intervreta- tion the name Fustiaria would be, of necessity, restricted to the Recent species, Dentalium eburneum Linné, D. philippinarum Sowerby (1860: 98) here illustrated, pl. IX, fig. 7, and possibly D. siculum Pilsbry and Sharp (1897:107). Rather than change the generally accepted, and apparently the original, concept of Fustiaria, the writer believes it would be advan- tageous to consider the designation of Newton and Harris to be invalid because Stoliczka’s original list of species assigned to Fustiaria did not inelude Dentalium eburneum of Linné. Under this interpretation, the validation of the genotype species would date from the next available designation. In addition to Newton and Harris (1894:64), Cossmann (1888:9) and Saeco (1897:112) invalidly designated Dentalinm politum Linné (1767:1264) the genotype. Following Cossmann’s (1888:9) ex- panded concept of the subgenus, Pilsbrv and Sharp (1897:127) validly designated D. circinatum Sowerby (1823:f.5) the genotype snecies. The writer proposes that the designation of Pilsbry and Sharp be accepted 87n literis, 1952. 4See Moore. R. C., p. 14, 1950. 5Recent specimens also have been referred to this species by a number of writers. Emerson—Notes on the Scaphopod Mollusca 203 as the first available designation with Dentalium circinatum Sowerby (1823) here illustrated, pl. IX, figs. 1, 3, the genotype species. PSEUDANTALIS Monterosato, 1884 Monterosato (1884:32) proposed Pseudantalis without designating a genotype for a heterogenous group of species, namely: Dentaliwm fissura Lamarck (=subgen. Fustiaria), D. inversum Deshayes (=subgen. Grapt- acme), D. rubescens Deshayes (=subgen.?Laevidentalium), D. tenuifissa) Monterosato (=subgen. Fustiaria), and D. filum Sowerby (=subgen. Episiphon). Pilsbry and Sharp (1897-127), following the usage of Fischer (1885:894) and Cossmann (1888:9), placed Pseudantalis in the synonymy of Fustiaria Stoliczka (1868:439), but did not designate a type species. Subsequently, Pilsbry (1939:139), remarked, ‘‘ Pseudan- talis Monterosato, Nom. Gen. e Spec. Conch. Medit., p. 32, (1884) was proposed for several species but without designation of type,’’ and com- pleted his note by stating, ‘‘P. rubescens (Dentalium rubescens Desh.) is to be taken as genotype.’’ Approximately eight years later Pilsbry (1947:31) commented in another note, ‘‘[the] type of Pseudantalis Monterosato, 1884, . . . was not stated in original publication, and I be- lieve not elsewhere. Dentalium fissura Lamarck is now [here] designated type.’’ Sacco’s (1897:111) designation of ‘‘P.[seudantalis] rubescens Desh. [ayes]’’ as the genotype species of ‘‘Sottog. Pseudantalis Montrs. 1884’? apparently is the earliest available designation. This species, on the basis of its apparent lack of a long, medial apical slit, is generally assigned to the ‘‘subgenus’’ Laevidentalium Cossmann (1888:7), genotype by orig- inal designation: Dentalium incertum Deshayes (1825:362), here illus- trated: pl. IX, fig. 9. If the two units were considered to be synony- mous, Pseudantalis (1884) would be a senior subjective synonym of Laevidentalium (1888). This interpretation would constitute an un- fortunate nomenclature change as Laevidentalium is commonly used for most members of the Dentaliidae which possess a smeoth, non-seulptured shell surface. Fortunately, there appears to be justification for the allocation of Dentalium rubescens to the subgenus Fustiaria; thus retaining the gen- erally used concept of Pseudantalis as a junior subjective synonym of Fustiaria. Monterosato (1884:32-33) and Boissevain (1906:60), have pointed out that the apical features of D. rubescens sensu lato vary considerably among individuals from the same population. As described by Deshayes (1825:363), the ‘‘typical’’ form of this species is char- acterized by the possession of a long internal groove which usually terminates at the apical rim in a small usb-triangle notch see pl. IX, fig. 8. In other specimens a long, narrow, medial slit cuts the convex surface of the posterior portion of the tube, see pl. IX, fig. 11. In some individuals, the apical slit is not continuous, being blocked by a closure in the slit, see pl. IX, fig. 12. Monterosato (1884:33) recognized the diversity of the apical features and proposed the name tenuwifissa to dis- tinguish the fissured form. Due to a scarcity of specimens for compari- son, most subsequent authors, including Pilsbry and Sharp (1897:107, 129) and Boissevain (1906:59-60), provisionally assigned Monterosato’s fissured form, ‘‘D. tenuifissa,’’ to the subgenus Fustiaria and placed 204 Proceedings of the Biological Society of Washington the externally unslit form, D. rubescens, in the ‘‘subgenus’’ Laeviden- talium. On the basis of the available data, D. tenuifissa appears to represent nothing more than an infrasubspecifie form of the D. rubescens species complex. The writer proposes that the generally accepted concept of Pseudantalis, be retained by allocating the apparent genotype species, D. rubescens Deshayes, to the subgenus Fustiaria. Under this interpre- tation, Pseudantalis would continue as a junior subjective synonym of Fustiaria. It should be noted that the development of polymorphic apical char- acters in the species comprising the subgenus Fustiaria considerably re- duces the biological significance of this ‘‘subgeneric unit.’’ It is quite evident that the higher categories of the Dentaliidae require a thorough re-evaluation in the light of present knowledge. Such an evaluation is beyond the scope of this paper. CONCLUSION On the basis of the data presented above, Pseudantalis (genotype: Dentalium rubescens Deshayes, 1825) is a junior subjective synonym of Fustiaria (genotype: Dentalium circinatum Sowerby, 1823). ACKNOWLEDGMENTS The writer is indebted to Dr. L. G. Hertlein of the California Academy of Sciences, Dr. N. H. Ludbrook, and Dr. W. J. Rees of the British Museum of Natural History for providing data, specimens, or aid in the completion of this paper.
