THE present more or less preliminary survey aims to cover the Australian Region in the broad sense, including thus New Guinea and the islands westward to Celebes, Australia, Tasmania, New Zealand, and the various Polynesian islands. It lists the known Chilopoda, Symphyla, Pauropoda, and Diplopoda and adds diagnoses of numer- ous new forms in the Museum of Comparative Zoélogy. By far the greater number of these occur in extensive and highly interesting collections made by Dr. W. M. Mann in the Solomons, Fijis, and in Australia (127 species) and by Prof. W. M. Wheeler in New Zealand, Australia, and in the Hervey and Society Islands (63 species). Among other collections may be mentioned those made by Dr. Thomas Barbour chiefly in New Guinea and the Moluccas (21 species), by Mr. G. H. Hardy in Tasmania (14 species), and by Dr. H. L. Clark in northern Queensland (9 species). CHILOPODA. SCOLOPENDROMORPHA. CRYPTOPIDAE. 1. Cryprops HAASEI Attems. Zool. jahrb. Syst., 1903, 18, p. 105.

OrocRYPTOPS VERDESCENS, sp. noy. Typre.— M. C. Z. 1,943. PaAratypes— M. C. Z. 1,944. Fijis: Nasoqo (W. M. Mann). Color dilute brown of a greenish tinge; head and caudal end of body orange or light ferruginous. Head not margined. From aberrans it is at once distinguishable in wholly lacking prosternal teeth, the anterior margin of prosternum CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION, 11 being wholly smooth, presenting merely a long, nearly straight chiti- nous edge which is slightly emarginate at the middle. Coxopleural processes long and acute; coxopleural pores extending dorsad to the tergite. Last ventral plate caudally incurved or somewhat angularly excavated. Anal legs very long and slender as in the preceding species; spines of prefemur both well developed, the ventral one about equalling the diameter of the joint at the level of its base. Length, 10 mm.; anal legs, near 6 mm. This species stands apart with the following one from all others in having tergites margined much farther forward, the margination being distinctly present from the seventh plate caudad. 20. OTOCRYPTOPS ABERRANS, sp. Novy. Typr.— M. C. Z. 1,941. Fijis: Nansori, Vesari (W. M. Mann). Color ferruginous. Head not margined, smooth. Antennae with first three articles nearly glabrous. Anal tergite with caudal margin mesally strongly bulging beyond lateral angles; the latter above with an acute spine. Ventral plates smooth, unfurrowed. Prosternum with anterior margin lightly convex, bearing two distinct black teeth on each side, of which the mesal is larger. Coxopleural process long and acute, much exceeding the ventral plate, pores reaching to the dorsal plate above. Anal legs very long and slender; femur with both spines well developed; the ventral larger, length less than diameter of joint. Length, near18 mm. Length of anal legs, near 8 mm. This species is readily distinguished from the others in having the tergites clearly margined from the seventh to ninth caudad. 20a. SCOLOPOCRYPTOPS MIERSI FIJIENSIS, subsp. nov. Type.— M. C. Z. 1,945. Paratyprs.—M. C. Z. 2,023. Fijis: Nasoqo, Nadarivatu (W. M. Mann). Scolopocryplops miersi has heretofore been recorded only from the Western Hemisphere. The present form agrees very closely with West Indian specimens in most details; but in the anal legs the ventral spine is much larger as is also the dorsal spine which is of about the same size as the ventral spine in mierst proper; furthermore, the ventral spine is farther distad than the dorsal one, the reverse being true in miersi, and it is nearer the middle of the length of joint (dis- 12 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. tance of distal edge of base of spine from proximal end of article to total length of article as 11:25 whereas in miersi it is as 11:31). Anal legs shorter. The strongly chitinous anterior edge of prosternum convex on each side, slanting a little caudad of ectad away from middle, its outer end elevated, dentiform, or not. Length, 42 mm., being thus considerably smaller than the average adult mierst. OTOSTIGMIDAE. 21. OTOsTIGMUS GLABER, sp. nov. Type.— M. C. Z. 1,933. Pararypes.— M. C.

Dorsal plate very finely and densely punctate. Antennae con- sisting of eighteen articles of which the first two and a half are glabrous. Dorsal plates from the fifth inclusive on with complete paired sulci. Eleventh dorsal plate margined, twelfth less completely so, others margined more or less completely, the twenty first most sharply so. All dorsal plates wholly smooth and shining, without trace of keels or tuberculation. Last tergite with a median longitudinal depression in front of the caudal angle. Prosternal dental plates each with four primary teeth of which the three innermost of each are fused excepting distally, the ectal one free and notched distally; sometimes only three teeth, with two innermost fused. Anterior ventral plates with sulci only across anterior border; but in the middle and posterior regions the sulci extend caudad to or beyond the middle of plate. Last ven- tral plate narrowed caudad, sides nearly straight, caudal margin weakly incurved, caudal corners rounded. Coxopleurae with long processes which exceed the last ventral plate by much more than their length; distally with two spinous points, laterally with two or three and dorsally with two (one on ectal and One on mesal edge), or often with but one. From first eight to first eleven legs with two tarsal spines, or some intermediate ones beyond the fourth with but one, the others to the twentieth inclusive with but one spine. Femur of the anal legs ventrally on ectal side with five to eight spines, ven- trally toward mesal side with three to six, on mesal surface with a series of two to four stouter spines, and on mesodorsal edge with two (or three) spines in addition to the one at the distal angle.

Antennae long, terete; last article about equalling the two preceding. Labrum with near twenty-six teeth of which the lateral are less chitinous and more finely tipped, the median ones (ten in number) stout and dentiform. Divisions of dental plate of mandible apparently simple. Prebasal plate not exposed. Basal plate trapeziform, the exposed part three and a half times wider than long; measured from edge of cephalic plate to caudal edge overlapped by first tergite, about 2.7 times wider than long. Prehensors rather weak, not attaining front margin of head, wholly unarmed. Prosternum also unarmed; without chitinous lines. Dorsal plates bisuleate. Last dorsal plate broad, shield-shaped. | Spiracles circular; first much larger than the second, the others decreasing gradually caudad. Anterior ventral plates excavated in front, with a triangular peg from caudal margin of preceding plate fitting into the excavation, the processes getting smaller in going caudad. Last ventral plate broad, narrowed caudad, caudal margin mesally emarginate. Ventral pores on the posterior middle part of the plate in a small subcircu- lar or subelliptic area. Pleural pores in two large pits on each side at the edge of the plate. Anal legs composed of six articles beyond coxopleurae, joints long and slender; no claws. Pairs of legs, fifty-nine to sixty-three. Length, 50 mm. This species is like the Brazilian A. plusiodonta (Attems) and unlike all other species in not having the prebasal plate exposed, but differs from that species in the simpler divisions of the dental plate, these not being dentate, the shorter prehensors, greater number of legs and other features. All the previously known species were from South America and the West Indies. 90. EucrRATONYX HAMATUS Pocock. Willey’s Zool. results, 1898, pt. 1, p. 66, pl. 6, fig. 2c.!

Queensland: Kuranda 2,000 ft., Sep- tember, 1914 (H. L. Clark). Unlike the type-species of Ballophilus, the Liberian B. clavicornis, which is deep violet or almost black in color, the present one is bright ferruginous, in life probably more red like various species of Linotaenia, though because of the readiness with which violet is lost in alcohol in various chilopods, this pigment may be present in this species in life. Head appearing much like that of a Linotaenia; with no frontal suture. Antennae moderate, clavate, the articles beyond the eighth being thickened; geniculate as usual. Prebasal plate a little exposed, more on each side of middle than at middle. Claws of prehensoral feet not reaching anterior margin of head. All joints unarmed. Basal plate broad, widest anteriorly. Anterior margin of pro- sternum concavely or subangularly excavated. Labrum serrate, processes pale, large, somewhat irregular. Body constricted a little ways back of the head in the usual manner; from there widening strongly to the posterior third of length and then again strongly attenuated caudad. The anterior region of the body appears extremely slender in comparison with the middle region. Dorsal plates crossed longitudinally by many weak sulci between which they are elevated and roughened, and in part somewhat scabrous. Ventral pores much more numerous than in B. clavicornis, densely arranged in an elevated, more strongly chitinous, transversely elliptic or oblong area on the posterior portion of plates; present on all plates from the second to the antepenult inclusive. All spiracles small, circular. Last ventral plate moderately wide, narrowed caudad. Coxopleurae of anal legs much thickened; each bearing two pits opening at and lying partly beneath the edge of the ventral plate. Anal legs (male) strongly crassate but not clavate as in B. clavicornis, the proximal articles being thickest. No claw present, this being replaced with a slight mem- branous point. Six articles distad of coxopleura. Densely shortly pilose. Other legs not much differing in different regions of body, all rather slender. Anal pores present, minute. _ Pairs of legs, seventy-five.

Brown above, but laterally and ventrally shows a distinctly greenish tinge, the pore areas very dark, deep brown or blackish. Head of usual general form, wider near middle and narrower caudally than in B. australiae. Labrum with fewer and weaker serrations than in that species, in large part appearing smooth. Dentate plate of mandibles with five teeth. Antennae of usual general clavate and geniculate form; last article longer than the two preceding together but shorter than the three preceding. Prebasal plate distinctly exposed. Basal plate nearly three times wider than long, angularly extended a little forward at middle. Last ventral plate equal in length and breadth, narrowed caudad. Anal legs strongly crassate as usual, somewhat clavate in male. Coxopleural pores large, only inner edges covered by ventral plate. Pairs of legs, eighty-one to ninety-one. Length, up to 52 mm. 93.

This species has a very characteristic color appearance on account of the generally black head, prosternum, prehensors, basal and first dorsal plates, and antennae, and the somewhat brownish appearance of the dorsal plates each of which is typically crossed over the caudal border by a darker band. ‘The head is of the usual long and narrow form, being nearly 1.88 times longer than wide; it is widest anteriorly, narrowing caudad gradually to near the posterior third and then more strongly to the truncate caudal end. The frontal suture, unlike that in M. tenwiculus, is very clearly evident throughout. Behind the suture and converging gently to the caudal margin are two rows of coarse, deeply impressed puncta which often give the impression of lying in continuous sulci. In front of the suture a pair of coarse puncta and in front of each of these a long seta. Anterior margin of head at middle subangularly emarginate. Lateral pieces of labrum with margins wholly smooth and even; middle piece abruptly nar- rowed at caudal end, but little widening cephalad from there. Man- dibles with nine laminae which are dentate throughout, the teeth smaller toward base; first lamina with only five teeth; external angle simple, not laciniate. Basal plate with a large shallow puncture or pit on each side toward the anterior corner; a few much finer puncta on the more posterior region. Prosternum with very sparse fine puncta; anterior oblique border crossed by two dark chitinous bands projecting anteriorly as slight teeth between which is an emargination. The femuroid is armed at distal end with a long, stout, distally blunt black tooth and the usual smaller one proximad of the oblique suture. The second and third articles with blunt black distally rounded nod- ules or teeth. The tooth at base of claw small, low, broadly sub- conical. Dorsal plates of middle and posterior region strongly bisul- cate and roughened, scabrous or corniculate, the anterior five or six plates smooth excepting for the deep puncta; paired sulci not present on first plate. Ventral plates each with a deep median longitudinal a CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 59 sulcus over about its posterior two thirds, this faintly bifurcate ante- riorly but conspicuously differing from the strong Y-shaped impres- sion of, e. g., punctifrons. Last ventral plate subtrapeziform, much less strongly narrowed caudad than in punctifrons, the caudal margin convex, each lateral border incurved near middle and again between middle and caudal end, the region caudad of second emarginations more depressed, densely finely hairy, the second region intermediate, similarly clothed, separated by a depression from the anterior region which is convexly elevated and clothed more sparsely with longer, coarser hairs. Inner aporous band of coxopleurae broader than in punctifrons, oblanceolate in outline, densely finely hairy; pores of coxopleurae much fewer and larger than in punctifrons; no distinct longitudinal sulcus or suture dorsally. Last dorsal plate much broader than in punctifrons, somewhat shield-shaped, the anterior margin being a little concave, the lateral ones convex and converging and the caudal end rounded. The posterior border a lighter area over which are lines suggesting the lines of the palm of the hand or fingers formed by dark chitinous areas arranged in rows; similar markings along caudal borders of other dorsal plates also occurring. Scutum over genital region with numerous densely arranged dark polygonal areas not arranged in lines. Anal pores present, distinct. Pairs of legs, forty-nine. Length, up to 45 mm. 136. MEcISTOCEPHALUS ANGUSTIOR, sp. NOV. TypE.— M. C. Z. 2,062. Society Islands: Tahiti (W. M. Wheeler). Pale ferruginous, the head and prehensors deep ferruginous. Cepha- lic plate 1.87 times wider than long. Differing in form from that of M. punctifrons, being smaller, proportionately narrower anteriorly, so that the sides converge caudally much less strongly; margin widely rounded anteriorly between the ends of the frontal suture, incised mesally between bases of antennae. Puncta absent from frontal region, few elsewhere. Two short parallel furrows in caudal region, these embracing puncta; closer together than their width. Ventral teeth of head close to lateral edge on each side, black, slender and acute. Femuroid of prehensors with two blunt, rounded teeth, a distal one and one proximad of the oblique suture. Claw and intermediate joints also armed. Anterior ventral plates each with a v-shaped impression in which the side arms are very short; in the middle and 60 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. posterior regions the impression is a simple linear furrow, the arms being quite obliterated. Paired dorsal sulci beginning on the basal plate and present on tergites from there caudad. Last ventral plate rather broad, trapeziform, the caudal margin rounded. Coxopleurae scarcely encroaching on preceding segment; pores fine and numerous. Last dorsal plate long and narrow, caudally rounded. Pairs of legs, forty-nine. Length, about 27 mm. 137.

As compared with M. nigriceps or punctifrons this is a decidedly more slender species of nearly uniform width over the anterior half, the posterior region attenuated. It is a much paler species, the body in general being uniform light yellow, the head and prosternum with prehensors reddish, the first tergite paler. The head with a pair of short longitudinal sulci in front of caudal margin, the plate in front of this with weak puncta not forming well-marked lines as in nigriceps. Labrum with mesal angles of lateral pieces rounded, not at all produced, their margins wholly smooth. Dorsal plates clearly bisulcate from the first inclusive caudad. None roughened, tuberculate or scabrous. Median sulcus of ventral plates sharply defined, bifurcation anteriorly obscure as in nigriceps. Last ventral plate proportionately wider than in nigriceps, not laterally emarginate, surface of uniform char- acter, caudal margin rounded. Last tergite proportionately narrower than in nigriceps, not shield-shaped, sides more weakly convex. Non- porigerous ventral region of coxopleurae wide, oblanceolate. Pairs of legs, fifty-one. Length, to 31 mm. 138. MecISTOCEPHALUS KURANDANUS, sp. NOv. Type.— M. C. Z. 2,066. Queensland: Kuranda (Wm. M. Wheeler). This species is easily distinguished from all others known in the character of the labrum. The lateral pieces have the margin wholly lacking cilia; but the mesal end of each is conspicuously crenate, the most mesal of the seven or eight crenations of each piece being more CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 61 dentiform than the others. The median piece of labrum is caudally much narrowed, the lateral pieces touching, or nearly so, ventrad of its apex. The mandible bears nine laminae which are dentate through- out, with the distal teeth longer than the proximal ones excepting on the first lamina which bears six teeth differing but little in length. Cephalic plate near 1.8 times longer than wide. The sternal sulcus bifureate anteriorly, the angle of the fork rectangular or nearly so. Coxopleurae of the usual general type with numerous small pores. Head and prehensorial segment chestnut, the body brown with obscure dusky mottlings. Young specimens show a greenish tinge posteriorly. Pairs of legs, forty-nine. Length of type, 84 mm.; greatest width, 3.2 mm. 139. M&rcIsToCcEPHALUS SIMPLEX, sp. nov. Typre.— M. C. Z. 2,067. Queensland: Cairns (W. M. Wheeler). Superficially this species differs from the preceding one, M. kuran- danus, in having the anterior angle of the sternal impressions of the anterior segments obtuse instead of rectangular. The lateral pieces of the labrum have the margin wholly without crenations such as characterize kurandanus. In the type the mandibles have seven pectinate lamellae; these are dentate to the base with teeth increasing in length from base distad. Head 1.66 times longer than wide. Pro- sternal teeth acute. Teeth of femuroid of prehensors stout and bluntly rounded. Pores of coxopleurae very numerous, small, with no specially enlarged ones. Head and prehensors chestnut, the body otherwise fulvous. Pairs of legs, forty-nine. Length of type, 40 mm. 140. MercIsTocEPHALUS MIMETICUS, sp. nov. Type.— M. C. Z. 148. Paratypes.— 2,149-2,153, 2,854, 2,855. Solomons: Fulakora, Tulagi, Auki, Wai-ai, Ngi, Pamua, Wainoni Bay (W. M. Mann). This species is remarkably like M. nigriceps in general appearance and structure excepting in having the number of pairs of legs con- stantly forty-seven instead of forty-nine. It has the head, prehen- sorial segment, antennae, and one or two more anterior segments similarly black and the caudal plates dark brown with the caudal 62 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. borders often darker. It is on the average a smaller species, but parallels the other closely in details. The mandibles, however, have but six laminae instead of nine, with the first one bearing six teeth; external angle with three or four setiform processes instead of being simple. Labrum less angular at middle. Length of largest type, 30 mm. 141. MeEcISTOCEPHALUS LIFUENSIS Pocock. Willey’s Zool. results, 1898, pt. 1, p. 63.! Locauiry.— Loyalty Islands: Lifu! 142.

Differing from Mecistocephalus sens. str. in having the mandibular laminae dentate only distally and the portion proximad of the teeth with margin densely ciliate to base instead of dentate throughout. It also differs in having the lateral pieces of the labrum densely ciliate throughout instead of being wholly smooth. 64 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. GENOTYPE.— D. solomonensis, sp. nov. Includes also D. gigas, subgigas, and wneifer. New Guinea seems to be the center of distribution of this group. 149. Dasypryx SOLOMONENSIS, sp. nov. Type.— M. C. Z. 2,147. Solomons: Ngi, Wainoni Bay, Tulagi, Fulakora (W. M. Mann). In this species the number of mandibular laminae is large, being twenty-three to twenty-six in the specimens examined. It otherwise differs from gigas, subgigas and wncifer in the much greater length of the marginal cilia of the laminae, these equalling or exceeding the width of the stalk instead of being very much shorter; and also in the obviously greater length of the distal teeth which are fewer and of which the more proximal ones are less reduced in length. Cephalic plate longer than wide in the ratio 1.53:1, being thus shorter than in the related forms. The teeth of the prehensors are short and stout and are often concave on the proximal edge but never truly uncate as they are in uncifer; claws only moderately curved, the edges wholly smooth. The coxopleurae lack any single specially enlarged pores such as are present in subgigas. Color of head and prehensorial segment chestnut, the remaining portion of body brown. Pairs of legs, forty-nine. 150. Dasypryx eiaas (Haase). Mecistocephalus gigas Haase, Abhandl. Mus. Dresden, 1887, 5, p. 105, pl. 6, fig. 111.1. Attems, Abhandl.

Median lamellae of mandible dentate to base, with the distal teeth long but the median and proximal ones very short. The labrum characterized by having the lateral pieces notably strongly extended caudad at mesal ends, the mesal angles acute and extending much caudad of lateral region of labrum; along the outer portion of each lateral piece a dense line of cilia extends beyond free caudal margin, giving the appearance of fringed margin.

A number of species occurring in Japan, China, the Philippines, etc., seem to have been confused under the name L. asperatus Koch. _It is difficult to believe that the species described by Attems from the Hawaiian Islands (Loe. cit.) is the same as that described by him from Japan in 1909 (Arkiv zool., 5, no. 3, p. 22). Of the first Attems states that the posterior angles of the seventh, ninth, eleventh, and thirteenth dorsal plates are produced, of the second that the sixth, seventh, ninth, eleventh, and thirteenth are produced, though some variability in the angulation of the sixth plate may be responsible for this. He gives the coxae of the last two pairs of legs in the Hawaiian form as unarmed ventrally, while they are armed in the Japanese form, the respective 1-2, 0, 2, 1,0 1, 0, 3, 1,0 formulae for the anal legs being 7-3 79 and 7739-7 and for the penult 1 0,3, 1,0 1,0,3 1,1 ~ 013,10" 1,3,2, O12 to 82d Fp zo. Assuming Attems’s observations to be accurate, it appears impossible that these two forms should be the same species. Further- more, both differ from the original description by Koch and from that given by Haase (Abhandl. Mus. Dresden, 1887, 5, p. 33) of Philippine specimens. Haase gives the ventral spines of the anal legs as 1, 1, 3, 2, 0, as does also Koch excepting that the latter fails to mention the spining of the first two joints. For the Hawaiian form I am here accordingly proposing a new name, to be used at least pending further elucidation of the Ethopolidae of Japan and the Pacific islands. It seems also highly probable that the Japanese species described by Attems in 1903 is not the true asperatus of Koch and Haase, not only because of the marked difference in the spining of the legs as above indicated but also be- cause of the fewer ocelli in the former, thirteen in three series as against nineteen to twenty-three in asperatus. The Japanese species described by Attems may accordingly bear the name Bothropolys spinosior, nom. noy. 188. Ernorotys ruGcosus (Meinert).

Victoria (W. M. Mann). Dorsum somewhat dusky brown, somewhat paler, more greyish, in mid- dorsal region, especially over the saddles, but a median longitudinal pale CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 81 stripe not sharply set off, though on some tergites a brighter line each side of median stripe leaves a darker median area geminate by a longitudinal pale line. Legs with darker markings, especially on femora and prefemora but the definite arrangement of these is difficult to make out. Antennae yellow. First division of antennae with forty-two articles; second division with near eighty; third division incomplete. Stoma saddles moderately elevated. Stoma small, on most plates attaining and projecting into the caudal emargination. First tarsus of first legs consisting of fourteen articles, the second of thirty- two. First tarsus of second legs composed of eleven or twelve articles, the second of thirty. First tarsus of third legs of ten, the second of twenty-nine. None of tarsi present with first division ending in spines but last several pairs of legs missing. Length, 11 mm. The type, not fully mature, seems to conform most closely to Gone- thina, a genus previously known from the West Indies, though with- out knowledge of the gonopods of the female this cannot be wholly certain. From G. grenadensis differing in coloration and in the coarser, more spinescent hair of the tergites as well as in other details. DIPLACROPHOR, gen. nov. A genus of the Scutigerini resembling Lassophora of Madagascar in having the tarsal pegs of the anterior legs alternating regularly in size. Unlike that genus but agreeing with Scutigera in lacking any spines in the series of setae of the prefemur of first legs. Agreeing also with Scutigera in the form and general number of articles in the divisions of antennae. Differing from the two genera mentioned in having spines of the middle tergites, which are numerous and closely arranged on the margins, each accompanied by a short hair-point as in Allothereua, etc. Genotype.— D. nitens, sp. nov. 199. DIPLACROPHOR NITENS, sp. nov. TypE.— M. C. Z. 2,132. Solomons: Tulagi (W. M. Mann). Dorsum with a longitudinal light greenish grey stripe enclosing two black lines between which is a somewhat orange colored median line; the stripe limited on each side by an edging of black. Lateral region on each tergite for the most part reddish but toward each side with two greenish grey spots edged with black, the black color about the two connected. Dorsum of head except laterally greyish green enclosing two longitudinal red stripes edged in part with black. Legs greenish grey with deeper colored annuli of which 82 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. those of the prefemur and femur are narrow; each tibia with two deeper and much longer dark annuli occupying the entire joint excepting a narrow light median annulus and a similarly narrow distal one. Tips of tarsi somewhat rufous. First division of antennae composed of seventy-two articles which, excepting the nodal and basals, are very short; second division missing. First tarsal division of first legs consisting of thirteen articles, the second of thirty-four. In the second legs the first tarsal division also consists of thirteen segments, the second of thirty-six. In the third legs the first of eleven segments, the second of thirty-two. In the fourth the first of nine segments, the second of thirty-one. The fifth have seven in the first and twenty-eight in the second; the sixth six in the first and twenty-eight in the second; the seventh, six and twenty-seven respectively; the eighth, seven and twenty- eight. All stomata rather short, reaching caudal margin and projecting a little into the caudal excavation. Anal styles of male slender, tapered, the anterior pair a little longer and curved, the posterior straight. Length (male), 13 mm. 200. ScuTiGgERA (?) sTRABA (Wood). Cermatia straba Wood, Journ.

Wheeler). A species close to H. plebeia (Hansen) and H. nivea (Scop.). The latter differs from plebeia and the present species in having the cerci with but few setae of which the distal are longer than the depth of the cerci and in having the metatarsus of the last legs bearing only two setae in the anterodorsal row, these being but little shorter than the diameter of the joint. The present species differs from plebeta, e. g. in CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION, 83 having six setae in the anterodorsal row on the metatarsus of the last legs instead of four and in the character of the claws. The anterior accessory claw is longer proportionately to the principal one and the anterior seta is well developed, equalling the accessory claw in length. Posterior exopods well developed, in length somewhat exceeding the depth of the tarsi. Cerci slender, about 5.5 times longer than the greatest depth and thus much more slender than in the Australian species /7. indecisa (Attems), the cerci of the latter differing also in the much fewer setae. Setae numerous, the distal ones clearly exceeding the diameter of cercus at their level. Length, near 6 mm. 203. HANSENIELLA CALDARIA (Hansen). Quart.

Locatity.— New Zealand: Central Otago: Lake Wakatipu, Ben Lomond! TASMANIELLA, gen. nov. A genus like Neoscutigerella and Hanseniella (Journ. Linn. soc. London. Zool., 1914, 32, p. 197) in having no median excavation in the caudal border of the last plate and thus standing apart from Scuti- gerella proper. It is like Neoscutigerella in having the setae of the dorsal scuta of a special type; but differs clearly, e. g., in having these much larger, rod-like but narrowing toward base, those in a series across the caudal border much exceeding the others in length; all directed caudad. On the first three plates an especially long tapering seta arising at each caudal corner and extending dorsad and somewhat forward, a corresponding one on fourth tergite smaller. Last tergite with a pit-like depression on the median part of caudal border. GENoTYPE.— 7’. hardy, sp. nov. 204. 'TASMANIELLA HARDYI, Sp. nov. Typre.— M. C. Z. 2,053, Tasmania (G. H. Hardy). Setae of inner surface of all joints of antennae directed obliquely forward, of ordinary length. Setae of middle whorl of articles of antennae of same length above and below. Setae of head much finer 84 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. than those of tergites. First legs smaller than the second but in no sense dwarfed; without exopods. Exopods on posterior legs well developed. Anal legs with anterior claw slender, more than half as long as the other one. Claws of first legs slender with the posterior one about three fourths as long as the anterior one. Cerci with a distinct clear area at distal end not lined or striped, but this part weakly ringed with constricting sulci; setae moderately numerous, the more distal ones approaching in length the depth of the cerei proximally.

Queensland: Kuranda (H. L. Clark). The general color above is dull chestnut, the caudal border and the over- lapped anterior region darker. Legs fulvous, the tarsi and the antennae of greenish cast. 86 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. Labral margin deeply excavated at the middle, the black tooth projecting into the incision short, obtuse, leaving most of the incision open. Surface of head shining; puncta above sparse, not deep, but toward labral margin becoming numerous. Antennal fossa basin-like, closed in front as well as behind by a ridge. Antennae very short as usual; attenuated distad, the sixth article more slender than the more proximal ones, cylindrical; seventh article short, rounded, with four sensory cones. Collum with anterior margin concave at the sides and bulging convexly forward at the middle. Caudal margin between angles semicircular. Pro- truding median region of anterior border set off by a fine transverse sulcus, but the latter short, not extending to the side regions. Surface smooth and shining, weak puncta present in a series across anterior border but absent or obsolete elsewhere. Second tergite very large; an anterior elevated border set off by a furrow that is narrow and shallow in the middle region but widens and deepens down the sides as usual; surface smooth and shining, not punctate. Surface of the other tergites also smooth and shining and without puncta. =. Surface of last plate similar to that of the others. Lower border set off by a very weak oblique depression. Tarsus of legs with a single spine above and well separated from the claw. Length (female), near 33 mm.; width, 16 mm. This species may be easily separated from those heretofore described by the structure of the vulva. In this the basal division is large with the two halves equal or very nearly so, not with the outer one much the larger and overlapping the mesal. The distal piece has the usual triangular form; its base obviously narrower than the width of the basal division; its outer side more oblique than the mesal; dark, strongly chitinous. 215.

Coarse puncta in a series across anterior border and a few on middle part of plate, the latter otherwise smooth and shining. Second tergite with margination as usual, the depression caudad of and above it of usual general form but much shallower than in C. kurandanum and scarcely present in the middle region. A vague transverse ridge a little behind caudal limit of anterior third of length; surface smooth and shining, weakly coriariously marked behind the ridge, more roughened in front of it. Other plates smooth and shining. Anal tergite also smooth and shining. Caudal margin very obtusely slightly angular at middle, the plate depressed above the angle. Tarsi with spine above claw as usual. Length (male), near 24 mm.; width, 11.8mm. Another specimen, an adult male, is only 20 mm. long and 9.2 mm. wide. It is darker than the type. Clearly differentiated from other known species in the form of the male gonopods. The posterior pair is characterized in having the movable finger exceptionally large and heavy and somewhat clavately widened above the base, much exceeding the immovable finger; the latter of a stout conical form, making a pronounced angle with the axis of the basal part of the joint. The anterior gonopods greatly smaller than the posterior pair; the immovable finger flattened, apically rounded; the movable finger pointed distad, the tip curving adaxially to or over apex of immovable finger. 216.

Number of segments (male) fewer, being only forty-three as against a minimum of fifty-four noted in the other species. Length, near 6 mm. A smaller and paler species than S. fijiensis. 253. SIPHONOTUS SENIOR, sp. nov. Type.— M. C. Z. 4,587. Paratypes.— M. C. Z. 4,588. Fijis: Nadarivatu (W. M. Mann). Color in general light ferruginous with the usual violaceous brown darker pigment over the background, this more dense anteriorly; antennae colored with same pigment of which there are also the usual markings on the head. Antennae short and stout, a little clavate; articles short. Face narrow, evenly attenuated ventrad. Prozonites in anterior region strongly depressed below the level of the metazonites, less noticeably so in posterior region. Last tergite free above, equalling the valves. Number of segments in the type, a female, eighty-five. Length, near 16 mm. An obviously larger, more robust species than those above described. Characterized in having the venter concave, the lower edges of the tergites extending below the level of the sternites along entire length of body, instead of only anteriorly. Hairs of dorsum very short and sparse. Hairs on front of head short, rather dense above, fewer on caudal surface. 254. SIPHONOTUS FRATER, Sp. Novy. Type.— M. C. Z. 4,589. Fijis: Levuka (W. M. Mann). A large species like S. senior. More uniformly colored than that species. While the depth of the orange or light color varies, the violaceous mottlings or dots are scarcely evident excepting on the an- tennae. Like S. senior the venter is concavely upraised above the level of the lower edges of the tergites but in the posterior region much less so than in the other species. The head is proportionately longer than in S. senior. Whereas in the latter species the distance from the eye to the lower end of the head ‘ CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION, 95 is equal to the length of the first tergite, in frater the length is greater, exceeding the first tergite in about the ratio 17 : 14. The anal somite appears shorter and broader, with the annulus less shortened ventrally. Body in general broader in proportion to length. Number of segments (female type), sixty-three. Length, near 12 mm. 255. SIPHONOTUS ETHOCEPS, sp. nov. TypE.— M. C. Z. 4,590. Paratypes.— M. C. Z. 4,591. Fijis: Lasema (W. M. Mann). Distinguishable easily from the two preceding species, which it resembles in the marked concavity or elevation of the venter above the edges of the tergites, in the form of the head. The latter is shorter in proportion to the depth at the upper end and about equals the length of the first tergite. Whereas in S. frater the head in profile is straight, or even slightly concave, from near the level of the eyes ventrad and in senior is likewise straight or very nearly so, in the present species the line bulges decidedly convexly a little below the level of the antennae. The hairs on the face proportionately longer and more evenly distributed. The coloration is much as in S. frater, being light ferruginous with lighter, more yellow markings but without the vio- laceous mottlings of many species. Hairs of dorsum short, numerous. Number of segments (female type), seventy-three. Length, near 11 mm. More slender than frater. 256. SIPHONOTUS SOLOMONENSIS, sp. nov. Typr.— M. C. Z. 4,960. Paratype.— M. C. Z. 4,961. Solomons: Fulakora (W. M. Mann). General color pale fulvous of a slight greenish tinge with anterior borders of segments darker, a weakly outlined pale spot in dark region on each side below. Antennae dusky over a light background, darker distally. Head subtriangular in outline, the line of face in profile not indented at level of antennae, weakly convex to lower end; sides nearly straight but slightly incurved a little above tip and above that weakly convex. Eyes more than twice their diameter apart. Antennae unusually stout and heavy, strongly clavately widened to fifth article, the sixth moderately narrowing distad, the seventh very small; exceeding head below by sixth and seventh articles or by these and part of fifth article. Head and antennae subdensely clothed with hairs of moderate length. 96 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. Collum of usual general form; more than twice as wide as head; in length about equal to the two succeeding somites. p Tergites extending on each side below level of pleurites, with dorsum strongly arched. Caudal margin of tergites below on each side essentially straight, the caudoventral corner rectangular, slightly narrowly rounded. Caudal edge of pleurite beginning ectally in front of caudal corner of tergite and running caudad of mesad, straight, inner caudal corner a little rounded, mesal margin straight, a little oblique. Somites not constricted, the prozonites depressed only a little anteriorly. Body proportionately broad and heavy. Hairs moderate in length, not stout, uniform. Number of segments (female type), fifty-nine. Length, to near 15 mm.; width, near 1.2 mm. 257. SIPHONOTUS SOCIUS, sp. nov. Type.— M. C. Z. 4,962. Paratrype.— M. C. Z. 4,963. Solomons: Fulakora (W. M. Mann). General color fulvous of a weak ferruginous cast. Antennae dark, purplish black, especially distally. Head similar to that of preceding species but in side view more pointed below with curve of face weakly indented at beginning of frontal region below which more strongly convex than in the other species, in upper clypeal region somewhat incurving and then convex above lower end. Differing from that species obviously in the antennae which are smaller, being both shorter and more slender and much more nearly cylindrical with the sixth article more strongly narrowed distad and all articles shorter. Collum differs in having lower posterior angle more acute, the lateral margin in front of it weakly widely concave. The transverse suture of segments in general more sharply and deeply impressed. Body as a whole somewhat slender and more strongly narrowed cephalad. Number of segments from near fifty-six to eighty-two. Length, to 13 or 14 mm. This form is very close to the preceding species from which it is separated with some hesitation, though when the two are placed together it may be distinguished by differences in color, robustness, and especially in form of antennae and face. Unfortunately no males are available for comparison. a re a i gs a re Ve : ' CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 97 258. SIPHONOTUS ATTANUS, sp. nov. Type.— M. C. Z. 4,967 (male). Paratrypes.— M. C. Z. 4,968 (males and females). Solomons: Atta (W. M. Mann). The general color is pale fulvous. Antennae proximally fulvous, the distal articles violaceous, particularly over distal borders. The profile of the head furnishes an easy means of distinction between the two species, this in the present one being evenly widely concave between level of gentle upper frontal convexity and lower end of head, sometimes angularly indented near middle of this line. Antennae proportionately more slender with articles relatively longer, the sixth article proportionately longer and only slightly narrowed distad; antennae typically not widening beyond middle from where either subcylindrical or a little narrowing distad. Collum widely depressed across middle; lower margin concave toward caudal end where it curves down making caudolateral angle of plate acute. Number of segments (male and female) fifty to fifty-two. Length, near 13 mm. May be recognized among other species of the Solomons by the form of the head. This somewhat resembles that of S. sociws but is longer and proportionately more slender, the sides of face less strongly converging ventrad. A notably more slender species than S. socius. Segmental sutures distinct but prozonites not sharply depressed, continuing evenly the dorsal line of metazonite, this line decreasing gradually beneath pre- ceding plate. 259.

Of a somewhat fulvous grey color with antennae dark as usual. Strongly characterized by the form and proportions of the head. This is extremely short, with lower part of face much less acute than usual; the width of face at lower level of antennal sockets greater than the length below this level; -in front view side of face typically more or less angled between antennae and lower end; in profile face is prominently convex at junction of vertigial and frontal regions below which it is straight. Antennae clavate, thick, joint short, much exceeding head because of shortness of latter. Number of segments in both type and paratype, fifty-four. Length, 11.5 mm.

Wheeler). : Of the known species apparently nearest A. rainbowi Brélemann but easily distinguished by the structure of the gonopods in which the seminal branch is deeply subdivided, the gonopod thus presenting four branches (Cladethosoma, subgen. nov.) instead of three (Australio- soma sens. str.) or two (subgen. Dicladosoma). The tibial branch is much broader; at the tip it is curved back uncately and on the mesal edge just proximad of the curved part presents an acute tooth. The seminal branch proper curves in mesad beneath and in contact with the apical portion of the tibial division, and is broadly expanded near the middle of its length; the branch from near its base and on the mesal side is more slender and straight, but little curved at the acute tip. The tarsal branch at its base is ectad of the seminiferous branch in between which and the tibial plate it curves and is there partly con- cealed. The coxa bears a long, cylindrical, peg-like process on the mesal edge of its distal end. The general color is chestnut-black with a broad longitudinal median dorsal yellow band bisected by a narrow dark stripe or line and with the keels also yellow, the gemination of the dorsal stripe not always evident in young specimens. Legs and antennae brown to somewhat chestnut. Anal valves blackish. Keels of second segment each with a single lateral tooth near ante- rior corner. Anal scutum much exceeding the valves; the cauda flattened, dis- tal margin incurved or notched. Length (male), near 35 mm.; width, 4 mm. 106 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 201.

Gonopods of male very short, scarcely reaching the bases of the anterior legs of the preceding somite. Length, near 18 mm.; width, 1.8 mm. CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 109 299. ZELANODESMUS AUSTRALIANUS sp. nov. Tyre.— M. C. Z. 4,892. New South Wales: Southerland (W. M. Wheeler). Gonopods very similar to those of Z. rotornanus; the mesal spur of telopodite more transverse in position, making a more obtuse angle with the distal part, and also proportionately longer and more slender; distal branches also bending into a more nearly transverse position. The color-pattern is characteristic; each metazonite caudad of the transverse furrow is black while in front of this it is black at the sides but fulvous or greyish at the middle but with a triangular median black spot projecting into it from the caudal region; the prozonites are light with a black area each side of dorsum, and below on each side and often a small middorsal dark dot. Legs fulvous. It is larger than Z. rotornanus, the width being 2 mm. 300. ANTICHIROPUS VARIABILIS Attems. Antichiropus variabilis ingens Attems, Fauna siidw.

Differing from Antichiropus and closely related genera in the char- acter of the male gonopods. Readily distinguished from the same in wholly lacking spines or processes at the end of the long tibial or proximal division of the telopodite; the distal division of the telopodite consisting of a straight proximal subdivision at the dorsodistal edge of which there is (at least in the genotype) a thin short spine, and a strongly curled, thin distal blade which in the genotype crosses or interlocks with that of the other gonopod. The first legs as in related genera stout, with the third joint provided with a tooth at proximal end on ventral surface but not so strongly modified as in Antichiropus. Fifth sternite with anterior edge bearing the usual plate-like elevation but this low and thick in the genotype. Antennae of moderate length, distally clavate; second, third, and fourth articles subequal and but little longer than the fifth and sixth. Keels but slightly raised above CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 111 level of pleural surface, set off from above by a deep sulcus in the genotype; second keels below level of adjacent ones; keels from fifth caudad much thicker or more swollen than the anterior ones.

Dorsum deep chocolate to black, lower pleural and the ventral regions paler, ferruginous to testaceous. Antennae like dorsum, legs blackish or dark brown, proximally paler. Vertigial sulcus deep, extending ventrad to a little above the level of the antennal sockets, the sulcus at bottom of a wider furrow or depression. Face with numerous long straight setae, these above level of antennae fewer, along sides of median sulcus. First tergite with each lateral end rounded, the anterior corner more widely so than the posterior; above each lateral margin with a deep longitudinal furrow, margined below and a little ways up anterior side. Other tergites smooth and shining, the prozonites very finely coriarious, the metazonites smooth excepting in some certain obscure longitudinal rugae toward each side and more particularly caudad of the transverse sulcus. Metazonites from the fourth to the eighteenth inclusive with a deep transverse sulcus which ends on each side well above the level of the keels. Longitudinal sulci limiting keels above deep and sharply defined. Anal scutum narrowed caudad in the usual manner, the cauda rather wide and flattened dorsoventrally, not at all subcylindrical, the caudal margin truncate or mesally slightly notched. Dorsal surface, especially caudad of middle, obseurely transversely rugose; with two transverse series of setae additional to those projecting from caudal end, one near middle and one a little in front of caudal border. Anal valves sharply defined mesally. Anal seale caudally convexly rounded, convexly elevated between the two setigerous tubercles. Length (female), to near 16 mm.; width,2.5mm. The males more slender, the width of a specimen 15 mm. long being near 1.8 mm. 307. AKAMPTOGONUS BEAUFORTI Attems.

Metazonites above deep chocolate, the keels not paler, prozonites and sides lighter; the venter and legs fulvous; antennae distally dark brown, paler proximally. Dorsal surface not tuberculate or granular, shining, under lens appearing finely and not strongly coriarious. Vertigial sulcus of head deep, reaching hearly to level of upper margin of antennal sockets. Frontal and clypeal regions with numerous long stiff setae. Face in profile angularly bent forward at lower level of antennal sockets. This species stands apart with O. bisulcata Pocock from Burma in having the tergites mostly crossed by sharply impressed median longitudinal sulci in addition to the transverse sulci; but in the present species this longitudinal sulcus is distinct even on the first tergite and all others to and including the nineteenth whereas it exists only on segments from the third to the eighteenth in bisulcata. The keels are very narrow but thick dorsoventrally, with pores toward lower margin of edge; posterior angles not produced in any. Last tergite of usual form, notched caudally; crossed with a basal, submedian, and subapical transverse series of setae. Other segments with a series of setae across anterior border of meta- tergite. In the male gonopods both the coxae and telopodites very long. The latter clavately widened distad from a narrow base; each on the mesal side distad of middle with a branch in the form of a broad thin plate with distal end concavely excavated and dorsoventral face concave. The principal branch is also thin and flattened and is geniculate, bending abruptly mesad near its middle, its ventral surface concave. Opposite the mesal branch the seminiferous branch arises, this bending obliquely across the main branch and extending distomesad in contact with the mesal and ventral surface of the latter; just above the origin of the seminiferous branch a curved, slender and acute spur. Length, near 20 mm.; width, 1.8 mm. 309. ORTHOMORPHA COARCTATA (Saussure). Polydesmus coarctatus Saussure, Mém. Mex. Myr., 1860, p. 39, fig. 18.

Legs fulvous with middle joints darker and of vaguely weakly reddish cast. Head paler across labral border and just above antennal socket on each side. Vertigial sulcus sharply impressed to a little above level of upper margins ‘of antennal sockets. Antennae slender, joints long except first and last; third joint a little longest, the fourth, fifth, and sixth subequal. Tergites from third caudad with a median longitudinal sulcus, from fourth on with a transverse furrow which covers only middle region of plate and is often very shallow and sometimes vague.

Antennae and legs black. Articles of antennae shorter, as in S. nigrum, than in manni and maius. Furrows of tergites obscure. Keels as usual. Anal tergite broad, corners a little rounded, posterior margin a little concave. Most clearly differentiated by the structure of the male gonopods. The outer distal process is shorter than in S. nigrum, less ribbon-shaped, with the cuneate distal expansion much larger, bent so as to be con- cave on the ventral side. Most distal process abruptly narrowed and curved over distal portion as in manni. On ectal edge of tibial divi- — sion near middle of its length a triangular expansion with lower edge long and oblique and upper one short.

Vertigial sulcus as in the other species. Transverse sulcus of tergites distinct over median part of plates though not sharply impressed. Longitudinal median sulcus weak. Keels thick, with edges wholly smooth; set off by distinct furrows. Anal tergite more narrowed caudad than in the other species, caudally truncate or only slightly concave. Length (females), to 25 mm. Males smaller. Easily distinguished by the structure of the male gonopods. In the telopodite the broad mesal edge more strongly bent dorsad; the mesal distal process is broader proximally with the slender tip less curved. The outer process is of uniform width, ribbon-shaped to the end where it expands clavately a little and is truncate; it curves cephaloectad. 350. SOLOMONOSOMA CONFIRMANS, sp. nov. Type.— M. C. Z. 5,005. Paratype.— M. C. Z. 5,007. Solo- mons: Pamua (W. M. Mann). The coloration of this species is like that of S. nigrum, the dorsum including entire keels black excepting the obscure reddish middorsal spots. Legs and antennae black. In other general characters also agreeing with that species though obviously larger and more robust. Distinguished from S. nigrum and didymus in structure of the gono- pods. ‘These have the telopoditesshorter and proportionately broader. It may at once be distinguished from the first of these in the much larger outer triangular expansion on the edge of the telopodite which is also farther distad; and from the second in the form of the outer distal process which is of nearly uniform width throughout its length, lack- ing the conspicuous large cuneate expansion of the end. In didymus the inner distal process surpasses the outer one while in nigrum the outer is but little the larger; in the present species the outer process is obviously the larger, the inner being distally very slender and some- what angularly bent in its distal part. Just mesad of base of inner distal process the edge presents an acute tooth. Length, to near 30 mm. Mrmosoma, gen. nov. Composed of head and twenty segments. In general of the Ortho- morpha form. The second keel large and below level of the others; other keels decreasing in size caudad and may be essentially obliter- 126 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. ated on segments eighteen and nineteen; caudal angles short but more or less spinous. Anal tergite strongly narrowed caudad, rather narrowly furcate at end much as in Orthomorpha. Pleural keels present, often traceable as far as tenth segment or beyond. Sternites unarmed excepting processes from fifth oneinmale. Antennae slender, long, joints excepting first and last long, not much differing in length, the sixth clavately enlarged. First legs of male small, not thickened, the third joint without spur or other special modification. Char- acterized in structure of male gonopods. These much resemble those of Antichiropus in having the terminal seminiferous division strongly circularly coiled, the process arising on mesal side and curving first mesad, and then cephalad, ectad and back caudad and mesad. Unlike those of Antichiropus, however, the gonopods have the distal end of tibial division ending in a simply rounded lobe. GENOTYPE.— M. setoswm, sp. nov. 351. MIMOsOMA SETOSUM, sp. nov. Typge.— M.

Legs also whitish on proximal and distal joints with intervening ones dark. Keels with caudal angles produced, spinous. Lateral edge of keels in anterior and middle regions with two or three small but sharp teeth or serra- tions, the number rising to four in the posterior region. Tergite with sharply impressed transverse sulcus.

Legs whitish. The species also resembles setosum in having the dorsal surface roughened with gran- ules or minute setigerous tubercles; but this roughening is very much less marked with the hairs much sparser and rather weaker. The keels are proportionately smaller and obviously less elevated, the middorsal region appearing more arched, and the serrations on the lateral edges are much slighter. The keels of the eighteenth and nine- teenth segments not abruptly reduced as in the other species. The cauda is shorter and distally broader, subtruncate, not furcate, with angle on each side acute as in setoswm. Length (female), 14 mm. 353. MIMOSOMA GLABRUM, sp. nov. Typre.— M. C. Z. 4,995. Paratype.— M. C. Z. 4,997. Solomons: Auki (W. M. Mann). Similar in coloration to the preceding species but at once recogniz- able in having the antennae and legs uniformly pale throughout excepting that the last joint of the former has a narrow dark band about its proximal end. Antennae more slender with the joints shorter. The keels are wholly without serrations laterally and those of eight- eenth and nineteenth segments not abruptly reduced as in the other form. A most marked difference is that the tergites in the present species are nearly smooth, showing but vague traces of roughening and essentially glabrous, the hairs being scattered, short, and weak. The transverse furrow of tergites weak in strong contrast with the condition in the other species. Length (male type), near 10.5 mm. Female paratype much stouter and near 13 mm. in length. 354. MIMOSOMA SEQUENS, sp. nov. Type.— M. C. Z. 5,012. Solomons: Fulakora (W. M. Mann). This species resembles M. glabrum in having the tuberculation of the dorsum obliterated or reduced to fine obscure granulations with corresponding essential absence of hairs from most of surface. The tergites highly arched. Transverse sulcus obscure.

In coloration this species may be at once distinguished from those above described in having the antennae dark, deep brown or blackish, throughout while the legs are pale as in the other forms. In the type the collum is white but this may not be normal. The dorsum otherwise colored as in glabrum. Length, about 10.5 mm. 355. MIMOSOMA GRACILE, sp. nov. Typr.— M. C. Z. 5,014. Solomons: Wainoni Bay (W. M. Mann). This is like the two preceding species in being essentially smooth and glabrous; but unlike those species the transverse sulcus of the tergites is deeply impressed and pronounced nearly to the keels. The keels are small though sharply set off; angles of most not at all pro- duced, a few posterior ones showing short spinous points as in the preceding species; typically they show on the lateral edge two or three minute and widely separated denticles or points. Anal tergite rather strongly narrowed caudad, truncate at end. The dorsum is solid black. Like M. setoswm the first two antennal articles are light colored but at other end only the seventh article instead of both sixth and seventh is white, the intervening articles black. Legs white. A very slender species. Length, near 10.5 mm. SOMETHUS, gen. nov. Body having the general form of Strongylosoma; cylindrical, with the keels reduced, the second one below level of the others.

Surface of first tergite also obscurely roughened; with numerous setae, like those of the head, arranged in transverse series. Anterior margin forming an even convex curve from one caudal margin at middle a little incurved. Keels not serrate. Keels of second tergite with caudal corners subrectangular, a small tooth at anterior corner, one near middle of side and one between these two, the two caudal teeth bearing each a short seta, a similar seta also at caudal angle. Keels of third tergite like those of the second, as are also those of the fourth excepting that the posterior angles are a little produced and some- what less than rectangular while the anterior marginal tooth is more reduced. On the fifth keels the posterior angles are still more produced and more acute; the lateral serrations are weaker and more widely separated, the most anterior one smaller or nearly obliterated and another tooth evident nearer caudal corner. This extra posterior tooth evident on succeeding porigerous keels but not on the non-porigerous. In the posterior segments the teeth are weaker and often scarcely detectable. The angles become more and more produced and acute caudad. Anal scutum with five transverse rows of setae each of which arises from a small tubercle. Valves with mesal borders a little elevated, not set off with distinct sulci; each with two long setae. Anal scale triangular with caudal end truncate, bearing two long setae.

Sulcus crossing vertex of head sharply impressed. A weaker transverse depression or sulcus between antennal sockets which is cingulate, at middle, the angle open ventrally. Head with numerous straight and rather long hairs. Collum with a series of long erect setae along the anterior margin and another series parallel with the first and a little distance back of it. Keels of second tergite each with fine lateral serrations or teeth each of which, excepting the smaller one at anterior angle, seems to have been tipped with a long seta. Keels of third and fourth tergites with but three lateral serrations, those of the fifth and succeeding tergites with four. Cauda widely projecting beyond the anal valves, dorsally with six or seven transverse series of long setae. Mesal margins of valves conspicuously ele- vated, each valve with two setigerous tubercles. Scale strongly narrowed caudad; caudally truncate, a setigerous tubercle at each angle. In the gonopods of male the mesal spur extends mesodistad and then directly distad; the ventral branch smaller than the dorsal, both acutely pointed. The mesal of the two principal branches a little distad of its base is 136 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. geniculately bent mesad and then at once again distad, the distal part flattened and lanceolate in outline. The outer branch is slender and straight proxi- mally but is thin and expanded distally, its outer margin convex, the mesal straight, as a whole curved mesad to touch with its tip the tip of the mesal branch. Length, about 16 mm.; width 2 mm. PAURODESMUS, gen. nov. This genus is very close in its general structure to the Palaearctie Brachydesmus. Like that genus the body consists of the head and nineteenth segments and the general sculpturing is as in Polydesmus. It differs in having the keels more elevated, with the posterior angles produced into longer and more slender processes. The body is larger and darker than in that genus, more as in the usual Polydesmus forms. Unfortunately no male was secured so that the character of the gonopods cannot be given. GENotTyPE.— P. acutangulus, sp. nov. 367. PAURODESMUS ACUTANGULUS, sp. nov. Tyree.— M. C. Z. 4,660. Queensland: Kuranda (H. L. Clark). Color dark brown above, in the middle and posterior regions of a decidedly reddish tinge on keels and back of the principal transverse sulcus. Antennae moderately long, slender excepting the sixth article which is much thickened; lengths of second, third, fourth, fifth, and sixth articles respectively about .36 mm., .4 mm., 32 mm., .34 mm., and .43 mm. Vertigial sulcus fine, distinct. Collum equal in width to head inclusive of mandibles, obviously shorter than the second tergite. Laterally subacutely narrowed, the anterior margin evenly convex between the lateral angles, the caudal margin convex between inner ends of keels with mesal portion straight. Anterior and lateral border thin, flat or rather a little upraised especially laterally, not distinctly margined except adjacent to lateral angle a little mesad from which is a second fine longitudinal sulcus; the plane area of the border is extended further caudad at the middle; along the border is a series of well-separated setae, each of which is borne on a small nodule. The area of the collum behind the border is divided into larger setigerous areas or low flat tubercles which form fine transverse rows of which the more anterior are somewhat irregular and in- complete. On the other tergites there are the three transverse rows of large areas or tubercles as in Polydesmus, each tubercle bearing a bacilliform seta; in the CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 137 anterior row are eight, in each other row six tubercles, not including two elevated setigerous areas on each keel, of which the posterior one bears the pore. Each keel has laterally three distinct serrations to which in posterior segments a fourth is added at the anterior corner, each tooth bearing at its apex a bacilliform seta. The posterior angles of all keels from the second ecaudad are distinctly produced, those from the fourth caudad strongly so, the processes in the posterior region especially long and narrowly acute. ; Anal scutum strongly narrowed caudad; the cauda narrowly truncate, extending well beyond the valves; dorsal surface bearing numerous bacilli- form setae each from a small tubercular base. Valves narrowly but sharply margined. Anal scale triangular. Legs long; the tarsal joint especially long and slender. Length, near 13 mm.; width, 1.6 mm. 368. OPpISTHOPORODESMUS OBTECTUS Silvestri.

PLATYRRHACUS ATOPOGON, sp. nov. Typr.— M. C. Z. 4,677. Dutch New Guinea: Manokwari (Thomas Barbour). The general color above is uniform brown over the metazonites with the prozonites a deeper, blackish brown. Legs and antennae brown, paler, more testaceous proximally. Antennae exceptionally short; the joints short, strongly clavately thickened above base. Surface of head strongly granular; vertigial furrow as usual. The collum equalling the head in width; widest anteriorly with the lateral ends narrowly rounded. Anterior margin straight across the middle, the extreme lateral portion set farther caudad than the median portion. Caudal region behind lateral processes very strongly convex. Surface densely granu- lar; with four transverse rows of larger, prominent rounded tubercles of which those of the row across anterior border are closely arranged, while those of the caudal and two intermediate rows are widely separated. Second tergite wider than those following; lateral margin of keels with five teeth between those at the corners whereas the keels of the third segment have but three, of the fourth two and of the following ones three again or in the most posterior ones four. The teeth all angular. Pores on the oblique surface close to the lateral margin from which removed by less than the diameter of the ring. Surface of metazonites densely coarsely granular to the edges of thekeels; the tubercles of the three rows all prominent, well separated, those of the caudal row largest and projecting caudad of the posterior margin. The anal scutum is partly broken off; what remains, however, shows that it widens in some degree caudad of the base. The valves are unusually flat- tened, the mesal margining narrow and low, the two tubercles of each valve large and rising above the margin; surface granular. The anal scale with surface granular; subtrapeziform, the caudal edge mesally scarcely obtusely angular, the setigerous area large. The gonopods of the male are much shorter than in P. ancylogon. As in the 140 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. latter species the telopodite is uncate distally, curving mesad and then proxi- mad and again ectad. At the beginning of the distal curve a flat, slender, acute blade arises which runs mesad and curves but little beyond its base. © Dorsad of this the principal strongly curving branch divides near the middle of its length, sending caudad a branch which abruptly expands beyond its base into a plate malleiform in outline, the plate giving rise from its caudoectal corner to a slender acute style; the process beyond this branch continues as a slenderly pointed style the tip of which curves back ectad as mentioned. Length (male), near 37 mm.; width, 6.5 mm. The gonopods somewhat suggest those of P. (Eutrachyrachis) margaritatus Pocock, a species also described from New Guinea (Vic- toria Mountain). 383. PLATYRRHACUS ANCYLOGON, sp. nov. Type.— M. C. Z. 4,675. Paratypes.— M. C. Z. 4,676. Dutch New Guinea: Manokwari (Thomas Barbour). Deep chocolate to nearly black with a broad continuous median longitudinal yellow or testaceous stripe. Head with a distinct but not sharply impressed vertigial furrow. Surface densely granular. Antennae reaching to third segment. Collum wider than head. Decidedly widest anteriorly where it projects angularly on each side beyond a subquadrate posterior portion. Anterior margin straight except for a weak curving at the ends; caudal margin straight. Over the anterior border a series of larger tubercles behind which the plate is depressed; larger tubercles also along the caudal border. Surface in general densely tubercular or granular. The anterior keels strongly bent forward. Caudal angles in general a little more acute than a right angle but obviously produced only on the most caudal segments. The lateral margins with large angular teeth lower on the second and immediately succeeding plates, there being on second and third two triangular teeth in addition to those at the corners. On the fourth and immediately succeeding plates a broader and deeper incision which is less obvious farther caudad where the margin appears slightly concave from end to end and may bear more teeth, the number increasing to three and four between the large corner angles. Pore-ring rather small, remote from the margin, in the anterior region being nearly three times its diameter to the bottom of the nearest incision and in the posterior region rather less than once and a half. The tergites are coarsely granular over the keels and lateral part of dorsum of metazonites, the tubercles or granules becoming smaller and fewer mesad, the median yellow region being almost smooth. Anal scutum convex and elevated at base caudad of which flat. Slightly CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 141 widening from base to near middle of length and then strongly convexly rounded into a semicircle which is crenate, showing ten to twelve low crena- tions bearing long setae. Valves strongly margined, coarsely roughened and granular. Scale also granular, caudally weakly convex, with a large setigerous tubercle at each lateral end of caudal border. Gonopods of male with telopodite distally flattened and strongly uneate, eurving dorsad and then caudad and dividing into two long prongs of which the ectal is slender and acute, while the mesal one is proximally flat and blade- like but distally divided again into two slender acute prongs. Length, to near 55 mm.; width, 10.8 mm, 384. PLATYRRHACUS (DIODONTODESMUS) MIMUS, sp. nov. Typre.— M. C. Z. 4,983. Paratrypes.— M. C. Z. 4,984. Solo- mons: Fulakora (W. M. Mann). In the form of the gonopods much like P. verrucosus (Pocock); but the erect distal process is proportionately longer and more angu- late proximally, while the curving transverse prong, though very similar, takes its origin more dorsad and mesad than represented for verrucosus. It is a notably smaller species than P. verrucosus, the male having a width of only 5.2 mm. as against 9 mm. in the other species. The dorsum is but little arched, in this contrasting strongly, e. g., with gonethus, being more of the Polydesmus form. The keels typically weakly protruding only at ends, the intervening region merely con- cave or in some with one weak rounded tooth or angle or sometimes more. ‘The pore is on the oblique surface at the lateral border less than its diameter from the edge. On posterior plates the three rows of tubercles are distinct and subequal but on anterior plates the middle one may be more weakly developed and sometimes almost obliterated. Head strongly tuberculate throughout. Antennae heavy. Color deep brown, prozonites somewhat paler; lateral borders of keels light brown to obscure fulvous. 385. PLATYRRHACUS GONETHUS, sp. nov. Type.— M. C. Z. 4,981. Paratypes.— M. C. Z. 4,982. Solo- mons: Fulakora (W. M. Mann). General color dark brown with extreme lateral edges of keels narrowly yellowish or the lighter color sometimes not evident; prozonites of same color as metazonites or a lighter brown, in immature specimens often whitish. 142 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. Antennae of uniform thickness beyond basal joint, reaching to or a little beyond middle of second somite. Surface of head strongly granular excepting lower middle region of labrum which is smooth. Collum exceeding the head in width. Widest in front of middle of length, the caudal margin at sides bending more strongly forward to the lateral processes than the anterior. Surface densely tuberculate throughout, the tubercles larger laterad; a series of larger tubercles along anterior border and one along caudal. Second tergite wider than those following; teeth or projecting tubercles strongly marked along anterior edge; lateral margin also with sharply defined teeth, these four in number between the corner ones, as on the third and fourth tergites which are similarly strongly toothed on anterior edges of keels. Succeeding keels mostly normally with four lateral teeth, though some of the posterior ones have five. Teeth prominent but rounded and tuberculiform. Pores dorsal in position and removed from lateral margin by from three to four times their diameter (inclusive of rim). Dorsal surface of tergites with three transverse rows of large, rounded, well-separated tubercles; between these rows in middorsal region are scattered smaller tubercles, the surface otherwise roughened with finer granulations, while laterad and especially on the keels larger tubercles are present in the intervening spaces so that the rows of large tubercles as such are there often not distinctly separable. Anal seutum subsemicircular, a little more strongly convex in middorsal region, on each side of median caudal region three large but low crenations from each of which arises a large seta. Proximally with transverse rows of obscure tubercles; and on distal half two large setigerous tubercles. The gonopods of the male place the species in the relatively small group in which the primary distal prongs are subdivided. Gonopod anteriorly curving up dorsad and then caudad and again ventrad; near middle of anterior part of this curve arises the first or ectal prong which is simple, the ventrally directed tip acute; in the angle just above its base arises a much more slender, finely pointed process of about equal length; the principal, more mesal and dorsal, prong is tripartite, the ectal, more proximal, branch being straight and ex- tending subectad, the other two branches curved, with the mesal one a little stouter and longer than the other. Length of male (type), near 42 mm.; width, 8.2 mm. Width of female to 9.25 mm. 386. PLATYRRHACUS FALLENS, sp. Nov. Typr.— M. C. Z. 4,985. Paratype.— M. C. Z. 4,986. Solomons: Fulakora (W. M. Mann). Metazonites dark brown; prozonites with brown in a spot on middorsal region, on each side and ventrally, the intervening portions yellow; borders CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 143 of keels typically fulvous. In one female the prozonites are nearly uniform in color and the lateral borders of keels are not lighter. Surface of head uneven, most of it strongly granulotubercular, the granula- tions becoming finer toward clypeal region the lower part of which is smooth. Antennae moderately slender, uniform, light colored. Dorsum more moderately arched, much less strongly than in P. gonethus but more strongly than in mimus. Three rows of tubercles on tergites dis- tinct, the tubercles moderate or small in size, rounded, widely separated; on some plates the tubercles of median and anterior row are smaller in the mid- dorsal region. The very large pores are very characteristic, each situated on the border slope of keel about its radius or but little more from the edge. Lateral teeth of keels uniform, usually three between corner ones, on some four and sometimes, in the posterior region, five. Length (male type), near 55 mm.; width, 5.5 mm. Most easily distinguished by the form of the gonopods of the male which are of the type with more than two distal branches. The gono- pod curves up dorsally and back proximally as in P. gonethus, ete. On the ectal side at the beginning of the curve are two processes, a proximal one bending back proximad in a hook and a more slender straight one running dorsoectad and slightly cephalad. The main prong divides into two proximally directed, acutely pointed, processes of which the mesal one is larger and more curved. 387. PLATYRRHACUS SCHISTOGON, sp. nov. Type.— M. C. Z. 4,987. Paratrypes.— M. C. Z. 4,990. Solo- mons: interior of Malaita, Atta, Auki (W. M. Mann). Most like P. fallens in the character of the male gonopods. There are similarly two processes from ectal side but these arise farther up on the curve and are more separated at base with both running proxi- mad and the more proximal one but little more curving than the other. The principal prong bifurcates distally as in the other species into two curved branches of which the mesal is stouter and longer; but unlike the other species there springs from near the base of these two branches a third process which appears as a straight slender spur that runs ectad. The color is black excepting the lateral borders of keels which, with the legs and antennae, are yellow. As in the preceding species the posterior row of dorsal tubercles are better and more uniformly developed than the others. The pores are obviously much smaller and are removed from the lateral edge by somewhat more than their diameter. Lateral margin of keel normally 144 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. with two or three large rounded teeth, or in posterior region with one or two small intercalary additional ones, between the corner ones, the interval caudad of the first of these teeth larger and deeper. Head only weakly roughened, tubercles rather small and not dense. Length (male type), near 34mm.; width, 6mm. Width of female, 7.5 mm. 388. PLATYRRHACUS KATANTES Attems. Syst.

Head completely, or very nearly completely, covered by the first tergite. Antennae long; strongly clavate distad of end of third article, the fifth and sixth articles much enlarged, the seventh again narrower, subconical; the fifth article much the longest, in length about equalling the sixth and seventh together. Collum with ante- rior and lateral borders together forming an even semicircular line. The free border or rim crenate as in Lophodesmus, radial sulci simi- larly dividing it into ten lobes. Dorsum of tergites in general low, only weakly convex; the keels high, but little below highest part of dorsum and much above the middle level of the body. Keels broad, nearly horizontal, lateral and caudal border divided into lobes by radial sulci, the margin crenate or lobate. Surface of tergites includ- ing keels out as far as the border lobes covered with numerous minute tubercles or coarse granules; in addition two submedian longitudinal 148 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. rows of large tubercles and a row on each side, each of the four rows in each tergite consisting of three well-separated tubercles. Posterior angles of several plates produced. Pores on segments five, seven, nine, ten, twelve, thirteen, and fifteen to nineteen not borne on cones or special tubercles; each removed from margin, occurring on upper surface of caudolateral lobe. Anal tergite exposed from above; presenting two prominent ridges projecting caudad as rounded tubercles over the small, subconical pygidium proper. Coxal pieces of male gonopods small, not at all enlarged as in Lophodesmus though somewhat similar in form and position; the distal element very elongate, extending forward over the preceding segment and bifurcate into two short branches at tip. GENOTYPE.— A. atopus, sp. nov. 410. AIPOTROPIS ATOPUS, sp. nov. Type.— M. C. Z. 4,600. Fijis: Lomati (W. M. Mann). General color of metazonites above brown. The keels below brown dis- tally but fulvous in a broad band across base. Pleural region again brown and the venter fulvous. Legs fulvous. Antennae with background fulvous, the first four and the ultimate article tinged with brown. The head above level of antennae very densely finely tubercular and granu- lar. In the type the left antenna greatly exceeds the right in size, the latter probably a degenerated one. Rim of collum narrow, lobes considerably thickened. Middle region densely finely tubercular and granular; with two transverse rows of large rounded tubercles of which there are four in the anterior and six in the posterior. Keels of other tergites typically trilobate laterally; in the posterior region the most posterior of these lobes is separated off by a deeper incision and shows a tendency to subdivide as it does essentially on the three segments preceding the ultimate. On the caudal margin of each keel in all but several of the most caudal segments are three lobes, decreasing in size mesad, ectad of the outer longitudinal row of large tubercles the caudal one of which on each tergite projects as a lobe from the caudal margin; between the lateral row of tubercles and the corresponding submedian one are two weaker crenations on the caudal margin and also two between the two submedian rows. At the base of each caudolateral lobe on the porigerous segments a large special tubercle excepting on the seventeenth, eighteenth, and nineteenth somites on which the pores are more widely removed from the margin. Beginning with the sixteenth segment the caudolateral corners of the keels are produced more and more caudad, the processes of the twentieth extending straight caudad and distally narrowly rounded. CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 149 Apical blades of male gonopods extending forward parallel with each other nearly to the anterior edge of the sixth segment; inner branch at tip short, very slender, acute, curved with concavity ectad, giving exit to the semini- ferous duct, the tip lying close to or against the outer branch. Outer branch a flattened, distally somewhat expanded blade or plate. Length, 9.5 mm.; width, 1.75 mm. 411. ATIPOTROPIS INSIGNIS, sp. nov. Typr.— M. C. Z. 4,601. Paratypes.— M. C. Z. 4,602, 4,609. Fijis: Nadarivatu, Vanua Ava (W. M. Mann). The male gonopods are very similar in general structure to those of A. atopus; the principal or distal pieces are less narrowed below the bifurcation; a readily observed difference is in the inner or seminifer- ous distal branch which is stouter and distally less acute and beyond middle is not curved, extending straight distad well beyond and well apart from the outer division or plate. The coloration in general similar to that of the preceding species; but the longitudinal band on under surface of keels weaker and largely obscured by encroachment of the darker pigment and on some keels wholly eliminated. Prozonites with median dorsal reddish brown area broader than in atopus, the yellow band each side correspondingly narrower. Antennae with first four articles brown, the fifth and sixth white, the seventh with background white but darkened with brown especially proximally. Granular frontal region of head black- ish. In the first tergite the emarginations are much weaker and the lobes with free margins only slightly rounded, broader than in the other species. Median portion of plate more depressed with the large tubercles of the two transverse rows less conspicuous. ‘The surface of the tergites in general much more coarsely and strongly tubercular with the large tubercles of the four longitudinal rows much less prominent. The obviously more prominent tubercle cephalomesad of each pore in A. atopus not distinctly present in the present species. Pores on anterior plates considerably more widely removed from the margin. Lobes of keels in general less rounded, more angular. A larger, more robust, species, the length of the type (male), being close to 12 mm. with the width 2 mm. 412. AIPOTROPIS VARIANS, sp. nov. Type.— M. C. Z. 4,610. Paratrypes.— M. C. Z. 4,611. Fijis: Munia (W. M. Mann). 150 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. Coloration in general as in A. insignis. In the type the proximal articles of antennae but little darker than the others. Antennae shorter; the fifth article shorter in comparison with the third. The first tergite differs from that of the two other species in having a narrow rim in front beneath the free border and toward its caudal edge, this rim fitting with its lower edge against the head and expanding laterally into the usual end pieces. In the type it also differs in having twelve border lobes instead of only ten, the end lobes being subdivided; but in the young paratypical speci- mens the end lobes are large but not subdivided; whether always subdivided in adults it is impossible at present to say. The lobes of the keels in number and arrangement as in the other species. The marginal teeth more rounded than in A. insignis. Upper surface of tergites strongly densely tuberculate, the large tubercles of the four longitudinal rows prominent. A special eleva- tion or tubercle on base of caudolateral lobe of each porigerous keel; on the other keels a very prominent elevation proximad of the middle lobe. Differ- ing in that the caudolateral angles of the sixteenth keels are not or scarcely produced caudad beyond caudal margin, the seventeenth but little so, and the processes of eighteenth and nineteenth proportionately shorter. Dorsal cones of anal tergite large, not fully reaching end of cauda proper. Length, 9.5 mm.; width, 1.6 mm. 413. AIPOTROPIS LASEMANUS, sp. nov. Type.— M. C. Z. 4,612. Paratypes.— M. C. Z. 4,613. Fijis: Lasema (W. M. Mann). Distinguished from A. atopus and insignis in the structure of the gonopods. These are in general very similar. But they are shorter, reaching only to the anterior end of the prozonite, and are more strongly bowed mesad; the dorsal curve and the constriction at distal end less pronounced; the distal divisions are shorter and the mesal one on each side extends at first nearly horizontally mesad and then runs cephalad, the latter portion shorter than the former, crossing the one from the opposite gonopod, widely separated from the outer lobe and not extending distad beyond it or scarcely so. The apical division or blade with total length but two and a half times the great- est longitudinal diameter of the coxa as against three and a half times in A. atopus. Coloration similar to that of A. atopus excepting that the back- ground of the metazonites above is flavous with the dark brown or dusky color mostly confined to the coarser tubercles; first tergite entirely dark; ventral longitudinal fulvous band of keels more sharply limited than in atopus. CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. I51 In the first tergite the free margins of the lobes much less convexly elevated. Median region very similar but the tubercles in general rather coarser. Border lobes of othee tergites rather more thick- ened and somewhat more coarsely granular. The anal segment very similar. Anal scale longer with the caudal margin between the tubercles strongly convex or angular instead of nearly straight. 3 Length a little uncertain because of broken condition of the type, but about 11.5 mm.; width, 1.8 mm. PILOCHILUS, gen. nov. Agreeing in general with Aipotropis. The first tergite not quite completely covering the head in dorsal view, a little of the latter being exposed in front. Most readily distinguished from the genus mentioned in having the lobed free border vertical in position and extended ventrad into a supplementary band the lower edge of which fits against the head; in the other genus such a supplementary band is weakly indicated only at each caudolateral end of the border. The anal tergite is larger, the cauda extending prominently beyond the paired dorsal processes. The lobes of the keels are more serrate in form. The male gonopods are in general similar; but the terminal branches of the blades are longer and stouter, the seminiferous one blade-like, the outer branch wide, curved. Head entirely smooth, upper part not tubercular as in Aipotropis. Antennae long, all articles much longer than thick; fifth and sixth much thickened; the fifth longest.

Legs fulvous or testaceous proximally, becoming darker, light chestnut distally. : Head above very finely coriarious, with trace of tubercles or granules, below level of antennae the roughening somewhat coarser. Vertex crossed by a distinct median longitudinal suleus which ends far above the antennae, Antennae long, the fifth and sixth articles greatly thickened; fifth article much the longest, the third next. Free edge of first tergite but little elevated. The crenations or lobes broad and low. Surface but little elevated, densely finely tubercular throughout; with the usual two transverse rows of larger tubercles; these prominent, large, and rounded, the first row embracing four, the second six of which the two median ones are adjacent to the caudal margin. The surface of the tergites in general strongly densely tubercular. Four longitudinal rows of larger, more prominent tubercles as usual; three tubercles in each series on each tergite but the most caudal of these lower and often inconspicuous or almost obliterated as such; in addition on each side of the non-porigerous tergites between the lateral row and the lateral lobes of the keels a single large tubercle in line with a large elevated tooth projecting from the caudal margin. Keels laterally coarsely serrate, there being three teeth on the keels of the second to sixth tergites inclusive, and thereafter three on the non-porigerous and four on the porigerous keels. Caudal angles of posterior keels more and more produced caudad, the processes of the fifteenth to nineteenth in particular Jong and subacute; the processes of the eighteenth and nineteenth keels very slender. The caudal margin of each keel just mesad of the caudal corner with a large obtuse tooth, the edge mesad of this weakly serrate; but caudad the entire caudal margin of tergites more strongly crenate, the crenations finally be- coming more acute and on the eighteenth and nineteenth projecting as acute teeth. Pores above and well removed from margin, on base of caudal lobe, the surface about and beneath each one elevated as a low rounded mound. Venter of metazonites subdensely pilose. Last tergite large, triangular; at middle above two large conical tubercles and on each side in line with them a very slender marginal tubercle or cone; just proximad of the distal end a transverse row of four much smaller tubercles, theeone at each end marginal, setigerous; on each lateral margin toward base a long slender tubercle bearing a long stout seta; four long setae at tip of cauda. The apical pieces of the gonopods extending forward to the caudal edge of the ridge between the anterior legs of the sixth segment; they are rather broad flattened blades; the two terminal branches are both thin and flattened, blade-like, with the outer one curving mesad above the tip of the mesal one which is curved a little in the opposite direction.

Contrasting with the preceding species in having the tergites light brown instead of deep, almost black, brown. The lighter markings are as in the other species but lighter fulvous in color. The head is testaceous instead of chestnut, the first articles of antennae the same color, the fifth and sixth white as usual. It is in proportion to length a decidedly narrower species. The face is densely clothed with straight, moderately long hairs which extend up from clypeus to vertex. The crenations or free edges of the marginal lobes are somewhat higher; on the median portion are much more prominent, of low coni- cal form, instead of being very low and depressed. On the other tergites the large seriate tubercles are arranged as in the other species; on the anterior plates particularly they are rather more conspicuous, and more conical in form. ‘The serrations of the keels in general the same. A readily noticed difference is in the outermost large tooth on the caudal margin of each keel, this lying nearer to the lateral edge, with the excision between it and the caudo- lateral tooth or lobe more acute, the ectal side of the caudal tooth running a little ectad of caudad instead of clearly mesocaudad as it does in cynephor. The caudal margin of the tergites between the keels is more or less clearly crenate even.in the first tergites instead of remaining straight until the posterior region is reached. The large paired dorsal tubercles of the anal tergite are obviously larger than in P. cynephor while the corresponding marginal tubercles are smaller; the cauda beyond the principal tubercles shorter and narrower, whit- ish in color, its tubercles less prominent. Length, 15 mm.; width, 2.1 mm. ATOPODESMUS, gen. nov. Composed of head and nineteen segments. Antennae short and clavate. First tergite nearly completely covering the head from above; wholly lacking any distinct lobate border.

Prozonites and head fulvous, the latter punctate with brown above; legs, antennae, and porigerous cones paler, whitish. The head conspicuously tubercular above the level of the antennae, the outer row of tubercles on each side curving ectad above. Hairs of face numerous, exceedingly short. First tergite of usual form, presenting below a marginal lobate rim in which the emarginations are deep and the lobes well rounded; front face of the median portion steep, almost vertical; the height obviously exceeding the length; surface densely tubercular and with two transverse series of much more prominent tubercles which are widely separated, four tubercles in the anterior of these series and six in the posterior. Other tergites with three principal transverse rows of tubercles but an irregular and incomplete fourth row often traceable. Dorsal combs high, the three tubercles of each fused at base; the tubercles of the prominent lateral series also high and conspicu- ous. The submedian combs of three tergites preceding the ultimate pro- gressively higher, those of the nineteenth basally fused together and projecting caudad widely beyond the anal tergite which is thus completely concealed from above. The keels of the second tergite laterally trilobed with the median lobe smallest; the other non-porigerous keels laterally bilobed except- ing the seventeenth and eighteenth, which are trilobed. The porigerous keels are as if laterally trilobed with the caudal lobe subdivided and the pore-cone projecting freely between the two resulting smaller lobes. The marginal lobation and the position of the pore-cone readily distinguish this form from L. pusillus, the genotype, and the Javan lobulatus.

Free border of first tergite with the usual ten marginal areas. Elsewhere the tergite is strongly convexly elevated, and covered with numerous, closely arranged prominently protruding rounded tubercles of which eight are larger than the others. Other tergites crossed with four transverse rows of closely arranged tubercles of which the most anterior and most posterior are most poorly developed and the posterior in particular are often incomplete; the usual two submedian crests formed by rows of larger tubercles, three in each row on each plate, not very conspicuous, no similar prominent lateral row on each side; two rows of small tubercles between these.

It is a somewhat smaller and more slender form with similar structure and appearance. The keels are a little narrower and slightly less depressed. The transverse rows of tubercles are alike though with fewer tubercles in a row, normally twelve, as against fourteen in the average of 7’. conformans. The tubercles form distinct longitudinal rows whereas in conformans they are more singular. The tubercles of the two submedian longi- tudinal rows are much less prominent, being scarcely more elevated than the others on many of the tergites; correspondingly the ridges of the anal tergite are much lower and the lobes at their caudal ends do not project caudad of the adjacent lateral ones as they do in most species, the line of the apices of the four caudal lobes being thus nearly straight, the emargination separating off the anterior lobe on each side shallow the anterior lateral lobe equalling or exceeding in length the | one caudad of it, whereas it is shorter in 7. conformans. The lobation Lae CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION, 157 of the keels in general similar; but an obvious difference in that the excision opposite the angle of which the pore-cone stands is narrower and more caudal in position, not at the corner, the caudal lateral lobe thus extending farther caudad to the general line of the caudal margin of the tergite instead of lying obviously in front of it as it does in 7. conformans; the cones are lower, rather thick, a little more remote from the margin.

Median region of first tergite only moderately elevated, divided into large areas by weak or in part obscure furrows. On the second and third meta- tergites the region between the keels divided into only two transverse series of areas, while the succeeding ones show three. Of these the areas of the anterior series are largest, those of the posterior smallest and most irregular. The keels of the non-porigerous tergites each show three lateral lobes while on all the porigerous keels there are four. The caudal border of each keel shows two shorter sulci of which the more mesal is the shorter. The caudal margin of the second keel is nearly straight and transverse, while beginning with the second the margin curves more and more caudad in extending outward to the angle, the posterior corners in the posterior segments being strongly and sub- acutely produced. The caudal margin of the nineteenth segment alone is serrate, the projecting teeth six in number, acute. Last tergite triangularly narrowed caudad, the cauda very narrowly truncate.

Junus (OpHiuLUS) FALLAX Meinert. The occurrence of this common European species in Tasmania and New Zealand, doubtless due to introduction, is worthy of note. It agrees closely with J. fallax as represented in England and Ireland. The gonopods (New Zealand specimens) seem to differ slightly in having the anterior laminae rather narrower and longer with the inner branches not reaching quite so near to the distal end of the outer branch, though more extensive comparisons may show this difference inconstant.

New Zealand: Day’s Bay, near Welling- ton (W. M. Wheeler). Differs in many features of the gonopods from D. insulanus Attems. The median plate of the anterior pair is smaller and narrower; it has the anterior end mesally acutely incised. The mesodistal process of the coxal piece of anterior gonopods differs; the membranous lobe adjacent to this process on ectal side is more slender, not pointed distad, and is longer, much exceeding the distoectal lobe on the end of which, instead of short hairs, there is a series of many long setae like those of the posterior or distal branch of the gonopod. The latter branch instead of being subvertical extends obliquely from its attachment distomesad, its distal end lapping over the tip of the pos- terior gonopod as well as concealing largely the pseudoflagellum; with long setae at the end. The posterior gonopods somewhat inter- mediate between the form in D. insulanus and orophilus, the distal joint not sharply set off, a somewhat curved and slightly twisted thin process extending beyond the stouter, distally truncate and seti- gerous lobe representing the end of the first or principal joint, the setigerous lobe being smaller than in D. orophilus and larger than in insulanus. The general color is solid black throughout, excepting the middle part of collum and lower part of face, the extreme caudal margin of the anal scutum and the legs and antennae which are ferruginous; also an annulus about the caudal border of each segment is paler; the anterior region of annulus of ferruginous cast.

In the male gonopods the anterior median plate is very similar in form, but is proportionately longer and narrower. Coxal piece of anterior gonopods proportionately rather less elongate and _ less incurved on ectal side proximad of the ectodistal lobe; the latter bulging less laterad but extending decidedly farther distad and not pectinate, finger-shaped like the mesodistal lobe but less slender. 164 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. Number of segments, thirty-nine to forty-two as against fifty to fifty-five in EF. kaorinus. Width (female), to 2.2 mm. 443. EUMASTIGONUS DISTINCTIOR, sp. nov. Type.— M. C. Z. 4,872. Paratype.—M. C. Z. 4,873. New Zealand: Day’s Bay, near Wellington (W. M. Wheeler). Very similar in coloration to EL. kaorinus but the light markings more pronounced; a row of light spots along the lower: part of each side. Readily distinguished from the two other species in the character of the male gonopods. The anterior median plate is narrower than in either of the other species and at the distal end is straight or scarcely crenately notched, not deeply angularly excavated. ‘The coxal piece of the anterior gonopods lacks the pectinae on the outer distal lobe as does E. fasciatus; but this ectal process is much longer, exceeding the inner process, distally rounded. The inner distal process differs in being curved strongly ectad, the tip slenderly acute and bending back mesad. Anal valves more obviously margined; two short submarginal setae on each one. Number of segments, forty-one to forty-nine. Width (female), to 2.4 mm. 444. EUMASTIGONUS PARVUS, sp. nov. TyprE.— M. C. Z. 4,874. Paratypt.— M. C. Z. 4,875. New Zealand: Day’s Bay, near Wellington (W. M. Wheeler). Darker than the three preceding species and lacking distinct annu- lations of lighter color, the prozonites each in the caudal part of its overlapped portion with a narrow fulvous stripe across dorsum and a similar one down each side showing through the colorless overlapping zone of the preceding metazonite. Along each side of the body at the level of the pores a series of large light ferruginous spots and lower down toward the legs a series of smaller spots that fade out near middle of length. Collum, excepting marginally, vertex and lower part of head light ferruginous weakly darkened with a network of fine, largely obscure, dark lines. Anal scutum black, its basal border on each side and commonly the preceding metazonite light; anal valves either dusky ferruginous or nearly solid black. PINT Re CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 165 Agrees with FE. kaorinus and differs from fasciatus and distinctior in having a series of stout spines or pectinae at distoectal corner of coxal piece of the anterior gonopods. Unlike EF. kaorinus, these pectinae not borne on a distinct shoulder or lobe, there being a small distoectal process apart from the pectinae; spines much smaller than in kaorinus and not exceeding the series of spines across apex of telopodite in size. The inner distal process distally rounded, only slightly curved. Clearly differing from EF. kaorinus also in the form of the anterior median plate, this in the present species being distally rounded and mesally only vaguely indented, not deeply angularly excavated. Number of segments, thirty-six to forty-two. Diameter (male), 2.1mm. Short. 445. EQUMASTIGONUS MAIOR, sp. nov. Typr.— M. C. Z. 4,876. New Zealand: Day’s Bay, near Welling- ton (W. M. Wheeler). Having the usual pattern of coloration as exhibited in LE. kaorinus and distinctior. The light annuli ferruginous except a narrow margi- nal stripe across dorsum which is fulvous. A series of small light spots just above the pores and below toward ventral surface a series of larger light spots with above each on prozonite a narrow vertical light stripe. Collum mostly ferruginous with vague network of dark lines; anterior border black, the black band widening toward middle where it is connected by two black lines with a triangular black caudal area embracing two light spots. Head with usual color-pattern. Anal scutum black, valves light. Preceding segment also light. Legs light ferruginous. Most readily differentiated by means of the sculpturing of the tergites. On these the metazonites are closely longitudinally striate below, the striae on passing to the prozonite curving and running directly dorsad, the prozonites thus covered below with vertical, slightly wavy, and mostly continuous lines which on the anterior part are conspicuous up to the level of the pores. In the anterior region of the body the striae of the prozonites become more oblique and shorter. Eyes rather small. Composed of only three transverse series of ocelli. Collum smooth and shining. Narrowly margined below as usual. With a stria or sulcus nearly longitudinal, not paralleling the antero- 166 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY, lateral margin as more usually the case; a short stria below it and one or two short ones above. Anal valves not at all margined. Number of segments, fifty-five. Width (female), 3 mm. EUETHOGONUS, gen. nov. Differing from Amastigogonus Brélemann and Dimerogonus Attems in having the first pair of legs of the male armed with a distinct claw and the proximal joint not especially enlarged. In gonopods the characters are most like those of Amastigogonus. No distinct median plate; the tracheal stalks meeting directly at the middle line. Anterior gonopods with two long joints; a pseudoflagellum, this lying between these joints in a cavity which they form, rising to near the distal end of the gonopod but not protruding, slender and needle-like, not ribbon-shaped as it is in Amastigogonus. The posterior gonopods one-jointed as in the latter genus. Mandible with eight pectinate lamellae. GENOTYPE.— FE. hardyi, sp. nov. 446. EUETHOGONUS HARDYI, sp. nov. Type.— M.C. Z. 4,817. Paratypes.— M. C. Z. 4,818. Tasmania (G. H. Hardy). General color black, in the anterior region the prozonites often paler, particularly down the sides, from the inclusion of numerous light dots. There is also a tendency for the caudal border of the metazonites to be lighter, especially in a stripe down each side. Legs ferruginous. Antennae blackish. Sulcus across vertex of head distinct. Eyes transversely elongate, the mesal end angular, separated by less than twice their diameter. Ocelli in four transverse rows; e. g., 9, 8, 7, 6. Setigerous foveolae eight. Antennae reaching to the fourth segment. Collum moderately narrowed below, the anterior angle widely rounded. Margined below and up the anterior border to the level of the eye. Above the lower margining sulcus are two deep longitudinal sulci of which the upper one curves up dorsad at its anterior end. The transverse suture of segments strongly marked throughout. Pore well removed caudad from the suture which remains straight or but slightly widely curved opposite it. The covered part of the prozonites densely marked with fine transverse striolations which are closely beaded with shining granules; these striolations also on the anterior part of the exposed region of the pro- zonites above, extending back farther on the sides; on lower part of prozonites CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 167 some coarser striae arising obliquely or almost directly transversely from the anterior ends of longitudinal striae crossing the metazonites. Anal scutum covering the valves above; smooth. Valves smooth and shining, not at all margined. The posterior gonopods distinct from each other, with no» median plate; undivided, each in the form of a plate with edges bent more or less caudad and so producing a caudal groove; from ectal edge arises a digitiform process as in Amastigogonus lasmanianus but lower down and not extending distad as far as the tip of the main branch; the latter distally with several long setae. In the anterior gonopods the inner ends of the tracheal stalks meet firmly, being sutured, at the mesal line, the ends there expanded and forming a broadly triangular plate. In front of this lies a very small piece apparently represent- ing the true median plate which appears to be fused with the gonopods. The two branches of the anterior gonopods are equal in length and enclose between them a cavity in which the slender pseudoflagellum lies. Number of segments, sixty-one and near that number. Diameter of male, 3.2 mm.; of female to 4.2 mm. 447. ATELOMASTIX ALBANYENSIS Attems. Fauna siidw. Austr., 1911, 3, p. 194, fig. 73-80.! Locauity.— W. Australia: Albany 448.

The anterior gonopods flattened anterocaudally; near middle on ectal side a distally directed, finger-like process curved mesad at its distal end, separated by a distinct suture; adjacent to it on the mesal side and separated off from the basal part by an oblique suture is a broader flattened piece which bends back caudad distally showing a furrow mesad of its ectal angle and a longer pointed process or finger from its mesodistal corner. Anterior ventral plate in a single piece which is extended distad as a slender, distally rounded process. The posterior gonopods much shorter than the anterior, the latter curving back over them; distally rounded; flagellum terminal. The general color of the body black with the venter and lower part of sides fulvous, the light color rising higher on the metazonites than on the prozonites; frequently two longitudinal dorsal series of fulvous to somewhat ferruginous spots, the outline of the spots irregular, two on each metazonite with often a few much smaller light dots below each one. The collum lighter from numerous light areas separated by a network of dark as are also several succeeding tergites. Anal segment fulvous, the scutum darker over its caudal portion. Head fulvous below and on the sides, areolated over vertex similarly to collum and the clypeal region mottled. Antennae black excepting the seventh article. Legs fulvous. Each eye-patch subrhomboidal. Ocelli mostly in four or five series; e. g., 4, 4, 4, 4 to 4, 4, 4,4, 3. A lightly impressed sulcus across vertex of head. Antennae with fifth and sixth articles thickest, the fifth strongly clavate, the sixth more nearly cylindrical. CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 169 Collum with lower margin evenly rounded, not extending as far ventrad as the second tergite. Margin separated off by a furrow below and up the anterior border toward the dorsum. The ordinary segments deeply constricted, the metazonite, however, rising much higher than the prozonite. Pore located well caudad of the encircling furrow. Somites smooth above; longitudinally striate across both zones ventrally and a little distance up the sides. Meta- zonites normally clothed with numerous fine, suberect hairs. Anal scutum long, rounded or nearly straight caudally, exceeded by the valves. Valves not margined.

A smaller species than N. fijiana from which it may be distinguished at once in having a broad, fulvous to ferruginous stripe along the dorsum, a stripe along each side alone remaining black as the venter and lower part of the sides are light colored like the middorsal stripe. Anal segment black or mostly so. Legs irregularly dusky over a ful- vous background. Antennae dark, the seventh article not abruptly paler, fulvous, as it is in NV. fijiana. Antennal articles shorter; the fifth more strongly constricted at base. Collum more narrowed below, the lower end set off as a narrow rounded process.

Anal segment light excepting the caudal portion of the tergite and the entire ventral scale which are black. Legs in part dusky over a fulvous background. The antennae similar, being thus obviously lighter than in N. fijiana and lineata. The antennae are most nearly like those of N. lineata, the fifth joint, e. g., being similarly short with strongly constricted base, above which the article expands abruptly. A conspicuous characteristic of this species is in the rather finely and evenly but strongly roughened metazonites, especially dorsally, the coarser, low tuberculation or granulation here contrasting with the much finer grained even surface of the prozonites. Hairs numer- ous, short and straight. Number of segments, fifty. Length (female), 13 or 14 mm. 454. NESOCAMBALA SOLOMONICA, sp. nov. Type.— M. C. Z. 4,955. Paratyprs.— M. C. Z. 4,956. Solo- mons: Wainoni Bay (W. M. Mann). Resembling N. fiziana; but, aside from being an obviously more robust species, it differs in wholly lacking any series of light spots above and in showing a distinct annulation of the somites, the border of metazonite and the underlying part of prozonite being commonly light in contrast with the blackish remaining portion. Legs fulvous. Antennae dark. | Eyes subrhomboidal; ocelli in four or five oblique series, e. g., 3, 4, 4, 4,3. Fifth article of antennae strongly constricted at base, the sixth cylindrical. A sulcus across caudal portion of vertex, short but dis- tinct. Collum equalling or extending a little below lower edge of second tergite. Segments constricted as usual, with metazonites higher than pro- zonites, but constriction not so sharp or deep as in N. fijyiana. Striae rising part way up the side on a few anterior segments but on most confined to ventral surface and few though distinct, these crossing metazonite and curving dorsad on caudal edge of constriction but not crossing prozonite. Setae much shorter than in JN. fijana. CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 171 Anal tergite caudally rounded, much exceeded by the valves. Number of segments, 50-55.

A species with strongly marked color-character. The head and first four segments orange colored in sharp contrast with the remain- ing portion of body which is dark. Segments darkest in a stripe across metazonite in front of its paler caudal border, this stripe narrowing to an acute point down each side, a narrower dark process commonly also extending down prozonite; lower surface of segments pale. Anal tergite and valves and sometimes also the preceding segment light, typically orange like the anterior end. Antennae dark. Legs dusky over a light background. | Ocelli forming a compact black patch on each side, small, commonly in five series, ¢. g., 4, 4, 4, 4, 3. Sixth article of antennae long, cylin- drical to the abruptly narrower base; fifth article constricted proxi- mally as usual. Collum exceeded below by the second tergite. Segments strongly constricted as usual, the constricting furrow flat at bottom and crossed longitudinally by numerous exceedingly fine, beaded impressed lines. Striate beneath and half way up each side, the striae crossing metazonite and on prozonite bending dorsad and uniting with succeeding stria in each case. A marked feature is the dense clothing of segments with fine short hairs. Number of segments from forty-five (male) to fifty-nine (female). Length (female), to about 20 mm.; width, 1.2 mm. Male more slender. 456. JULOMORPHA FLABELLIGERA Silvestri. Abhandl. Mus. Dresden, 1897, 6, pt. 9, p. 11, pl. 2, fig. 56-57.1 LocaLiry.— Queensland: Cayndah|! 457. JULOMORPHA PODENZANAE Silvestri.

I am unable clearly to understand Brélemann’s account as to the localities he attributes to typical falcatus and his subspecies scobinula. He states (Op. cit., p. 125) that “the Gayndah specimens have been considered as a distinct subspecies for which the name of scobinula subsp. nov. is proposed”’ and on p. 128 that “There is, therefore, hardly any doubt that the Gayndah specimens belong to at least a subspecies different from the Cairns form.” The pertinence of the reference to Cairns is not clear. He may have had typical falcatus from that locality, though Silvestri’s types were from Gayndah. 475. CLapIsocricus (?) CONSIMILIS Brélemann.

Black, the segments caudally narrowly bordered with ferruginous. Legs and antennae pale ferruginous. Sulcus of head widely interrupted in the frontal region. Setigerous foveolae 2+ 2. Antennae short. Collum well rounded below. Margination in front obscure or absent. Second tergite extending well below collum, not flattened or excavated. Anal scutum covering the valves above, the latter protruding a little beyond it. Valves a little compressed; no margining sulcus. Branches of telopodite of posterior gonopods slender as usual but the outer or principal one slightly clavate and truncate at tip; the inner branch much the more slender and shorter, straight, acute, well apart from the other. Basal part of median plate between triangular and semicircular in form, the base line reentrant at middle; distal process about equal in length to basal part, slightly spatulate in form. Number of segments, forty-two to forty-eight. Diameter of female, up to 5.56 mm.; of male, up to 3.7 mm. Length of male type, 30 mm. Distinguished from other known Australian species in having the posterior margins of segments sinuate above the scobina as in various Fijian species, leaving the scobina in some cases freely exposed. Seobina occurring back to the thirty-first segment. Prozonites some- what depressed. Sutures on most segments obscure dorsally. Ex- posed part of prozonites smooth excepting for sparse, exceedingly fine and weak puncta and short lines; covered part with wavy fine trans- verse lines. Metazonites smooth. 568.

The general color is deep shining black, often somewhat olivaceous; the covered portion of segments brown with the border more reddish; caudal border red with the extreme margin fulvous. Legs greenish. Sulcus of head widely interrupted in the frontal region. Foveolae 2 + 2. Antennae not surpassing the second segment. Collum margined below and in front below level of eyes as usual, failing much of reaching lower level of second tergite. Covered portion of segments densely finely striate, the striae short, trans- verse, curving and in some degree anastomosing. Surface above elsewhere smooth and highly polished. Transverse suture or sulcus not present, ob- scurely indicated in a shallow furrow below. Segments striate beneath and on front region of ring higher up toward the pore. Caudal margins of some of the segments vaguely bisinuate. Anal scutum surpassing the valves. The latter compressed but margins not sharply set off. In the gonopods of the male the median plate has the basal region sublunate in form and longer than the distal process, the latter narrowly subtriangular, rounded at the distal end. Prongs of the telopodite of posterior gonopods subequal. Length, to near 80 mm.; width, 7.6 mm. A small species readily distinguished in having the anal tergite sur- passing the valves, the scobina extending to the thirty fifth segment, and the number of segments only forty-two to forty-four. 569. DINEMATOCRICUS FRATRELLUS, sp. nov. Type.— M. C. Z. 4,762. New Guinea: Manokwari (Thomas Barbour). Black, with the covered zone of segments more or less testaceous to ferrugin- ous. Legs dark brown. Suleus continuous excepting for a short distance in the frontal region. Foveolae 2 + 2. Second tergite extending much below the collum. Surface of the latter with fine short lines branching in coriarious fashion. Prozonites of most other segments also with some fine coriarious markings, the metazonites mostly wholly smooth. Suture distinct below but in middle and posterior region obscure in middorsal region. Posterior margins of most segments bisinuate, though not strongly so, over the scobina. Scobina long, occurring back as far as the thirty seventh segment. Anal segment with coriarious markings. Valves exceeding the tergite; inner borders compressed. In having the valves exceeding the tergite readily distinguished from D. erul which the species much Fs seam: in general features; it is a considerably smaller species. i 5 CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 191 Number of segments forty-eight as against only forty-two to forty-four in D. erul.

The general color is fuscous with the posterior borders of the segments rufescent. Legs and antennae brown to ferruginous. Head typically blackish with clypeal region and an area in frontal region ferruginous. Sulcus of head widely interrupted in the frontal region. Setigerous foveolae 2+ 2. Antennae very short. Collum rounded and margined below in the usual manner. The second tergite extending well below it, not excavated. The surface of anterior segments, like that of the collum, with numerous exceedingly fine impressed points from which obscure fine lines in places may be traced. In the middle and posterior regions the surface without such impressions, smooth and shining. Covered part of prozonite not striate in general. Segments broadly and shallowly depressed about the middle. Segmental sulcus obscure or mostly wholly absent across the dorsum. Seg- ments deeply striate beneath and up to near the pore; in several of the anterior segments, including the sixth or first porigerous, one or more of the upper- most striae curve transversely across the dorsum forming one or two complete deep sulci in front of the ordinary one. Scobina extending to the forty second segment; each consisting of a deeply impressed lunate area followed by the usual series of fine striae. Caudal part of the anal tergite set off by a sharply impressed transverse suleus. Caudal angle subacute, not surpassing the valves. Valves with inner borders compressed and elevated; not angled above, Number of segments fifty-two or fifty-three. Length (female), near 78 mm.; width, 7 mm. A species like D. undulatus and several other species in having the posterior margins of some of the anterior segments undulate over the scobina of the succeeding segment. 571.

The other seg- ments below the level of the pores also light olive with posterior border dark like dorsum but of a somewhat more brownish cast. Legs dense shining brown. Anal scutum blackish, uniform; valves similar but in the middle region dark olivaceous. Sulcus of head complete. Below level of antennae on each side a series of oblique striae, the striae of upper region fewer and much weaker. Surface in general shining. Collum of usual form, much exceeded below by the second tergite which is not excavated. The plate is margined only below, the margining sulcus not at all extending about the anterior corner. Surface very finely punctate among the coriarious markings. Fourth, fifth, and sixth plates with two transverse sulci; on the following segments only the usual transverse sulcus, this lying in a shallow transverse depression or weak constriction and distinct across the dorsum throughout. Surface of second plate similar to that of collum but in following plates the striae become more and more restricted to a longitudinal direction, soon forming a dense series giving the characteristic silky lustre as in D. sericoides and related forms. Scobina from eighth segment to the thirty ninth or fortieth; each a deep lunate impression within some finer lines in front of this. Angle of anal scutum very obtuse, rounded. Surface densely finely punc- tate, not striate, shining; from each lateral margin behind a series of furrows running mesad. Valves compressed; surface densely finely punctate, shining. Number of segments, fifty-five to fifty-eight. Length (male), near 105 mm.; width, 11 mm. This species may be distinguished from the related Fijian forms having a similar characteristic silky lustre by the different form of the male gonopods. The telopodite of the posterior pair has the inner branch slender and finely pointed as in these other species, the tip not extending beyond the middle of the length of the outer branch; the latter is characterized by being bent or coiled into two complete circles, one lying within or immediately over the other. 572.

Legs fuscous to ferruginous. Anal scutum and valves olive-black without lighter markings. CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 193 Sulcus of head fine and complete, though fainter near level of antennae, where crossed by several striae angled on the sulcus. Surface in general smooth and shining. Collum laterally well rounded; failing much of reaching the lower edge of the second tergite which is not at all excavated below. Surface appearing smooth and shining, very finely coriariously striate, the striae coarser below on each side. Second, third, and fourth tergites with dorsum crossed by a transverse stria; on the fifth tergite a weak anterior transverse stria and a deeper sulcus near middle but curving farther forward on each side with behind it on each side a shorter vertical stria paralleling it. On the sixth (first porigerous) tergite two complete deep transverse sulci, the ordinary segmental one which is strongly curved behind the pore and one in front of this beginning a little above the level of the pore. On the sixth tergite the anterior sulcus is weaker and on the seventh absent. Caudally the other sulcus becomes weaker and weaker above to very obscure and finally quite absent. Covered part of tergites coriariously striate, the striae chiefly subvertical; elsewhere the surface is very densely marked with fine longitudinal sulci which give a silky lustre as in D. holosericeus. Scobina from the eighth to the thirty fifth seg- ment; each a deep lunate impression with fine striae behind it. Anal scutum short, the posterior angle very obtuse, not free, exceeded by the valves, surface shining, less dull and silky appearing than the other tergites but similarly crossed by numerous longitudinal striae which, however, are coarser and less regular. Valves but slightly compressed, smooth, and shining, without striae excepting a series of weak ones across upper border. Number of segments forty-seven to fifty-one. Length (female), 82 mm.; width, 8.5 mm. The males proportionately somewhat stouter, a specimen 78 mm. long having a width of 9 mm. Evidently close to D. holosericeus Brélemann, but readily distin- guished by the form of the gonopods. In these the distal lobe of the median plate is proportionately somewhat longer, more angular at apex and narrower across base; the distal piece of the posterior gono- pods has the inner branch even smaller than in D. holosericeus but the most pronounced difference is in the outer branch which bends strongly first toward the body, then ectad and then at tip curves back in a hook. 573.

Also the scobina extend caudad only to the twenty third somite instead of to the thirty second. 575. DINEMATOCRICUS BIONUS, sp. Nov. Typr.— M. C. Z. 4,727. Solomons: Bio (W. M. Mann). Color olive-brown. Legs deeper, somewhat purplish brown of olive cast. Suleus of head interrupted near middle, elsewhere sharply impressed. Foveolae 2 + 2.

Suture traceable across dorsum on all segments but more distinct in anterior region. Transverse striae well marked below level of pore, then more oblique; on the fifth and sixth segments a transverse sulcus in front of the suture which is much deeper than the latter, a similar sulcus also on the second, third, and fourth segments but the ordinary suture obsolete on these segments. Scobina transversely elongate, separated from each other by only their own width; each a deep lunate concave impres- sion followed by a finely striate area of a low triangular form; present on segments from the eighth to the twenty eighth inclusive.

Sulcus on head discontinuous near middle and again toward the labral region. Foveolae 2+ 2. Median incision in lower margin wide, the tooth correspondingly broad, distally truncate or rather slightly concave. Collum margined below and more weakly about the anterior corner in front, with a fine longitudinal sulcus or stria, as is frequent, at level of eye on each side, joined above by two short transverse ones. Surface coriarious, the markings coarser below. Not reaching lower level of the second tergite. Surface of other tergites in general marked with numerous exceedingly fine puncta which caudad on each segment tend to give rise to exceedingly short, fine, longitudinal striae. Below level of pore with numerous longitudinal striae forming an obtuse angle at the suture, a few more widely separated ones also above level of the pore. Suture fine, extending up to level of pore about which it bends but obsolete above this level. On the more anterior segments, however, the suture is distinct entirely across the dorsum and in front of it on each side one or more of the striae above the level of the pore curve transversely and are elongate, on the fifth, sixth, seventh, and eighth segments forming a complete secondary sulcus in front of the ordinary one. Scobina small and short, lunate pits occurring on segments from the tenth or eleventh to the twenty fifth. Anal valves exceeding the tergite, protruding, but mesal borders scarcely set off by compression. Surface of valves and tergite with numerous ex- ceedingly fine points as in other segments but otherwise smooth. Number of segments, sixty to sixty-two. Length (female), near 150 mm.; width, 13.5 mm. A second female has a width of 15 mm. The species may be readily distinguished by the structure of the gonopods. In these the median piece has the basal part transversely oblong with the anterior margin convex; the distal part exceeds the basal in length, and is constricted at base, above which it is oblong- lanceolate inform. The telopodites of the posterior pair are very long and cross each other in the middle line; the outer piece is especially long and evenly curved, becoming very fine distad; the inner branch is very short and slender in comparison with the other, lying much below the middle of it. 577.

Sulcus of head nearly complete, only narrowly interrupted in frontal region. Foveolae 2 + 2. Antennae extending to third segment. Segmental suture not clearly defined, the keels present on metazonite above continuing upon prozonite without complete interruption though not so uniformly as in D. decipiens. The keels are low but narrower and more sharply defined than in D. decipiens; not present as such below pores, though the flat region between the striae are similarly dark colored as in the dorsal region, the stripes wider; usually thirteen keels on dorsum of each segment between pores. Posterior margins of somites not sinuate. Scobina much narrower than in D. eutropis, ceasing at somite XVI. Number of segments, thirty-five. Length (female type), 41 mm.; width, 5 mm. 578. DINEMATOCRICUS EUTROPIS, sp. nov. Typr.— M. C. Z. 4,929. Fijis: Nagasu (W. M. Mann). Prozonites a pale, somewhat greyish olive; metazonites abruptly a much darker color, deep brown.

Antennae short, not extending beyond collum. Foveolae 2 + 2. Second tergite extending much below level of collum. Sutures of segments clearly and uniformly impressed. Pore in line with suture which bends sharply about its posterior portion. Metazonites entirely across dorsum and down sides below pores as well with numerous sharply elevated, rather thin, keels which end abruptly in front at the median suture; below middle the keels decrease in height becoming finally merely the sharply defined lower edges of the strongly impressed striae; usually about twenty-five keels on dorsal region between pores. Between the median and anterior suture are somewhat oblique longitudinal sulci each with one edge elevated into a narrow low keel these keels more numerous and much more weakly developed than those of the metazonite, being obvious only under the microscope.

M. Mann). The sides are black in color without lighter markings. The dorsum be- tween the pores is of a lighter shade, typically dusky over a fulvous back- ground or in part with a somewhat reddish tinge, crossed longitudinally with black lines along the sulci; beginning near the middle of the length there is a brighter fulvous median dorsal longitudinal stripe which is narrowly pointed anteriorly and regularly widens caudad to the last scutum, the same band sometimes represented farther cephalad by a series of disconnected light dots where there may also be a more lateral series of similar dots on each side. The anal segment as a whole fulvous to ferruginous. Legs bright yellow to pale ferruginous. The sulcus of the head is sharply impressed throughout its length. Foveolae 2+ 2. Collum well rounded below, margined as usual, the margining sulcus weak. Not attaining lower level of second tergite. The segments in general are strongly striate beneath and up the sides to the pore-level, with the covered part of the zonite smooth throughout. Above the level of the pore the dorsum is deeply longitudinally furrowed from the caudal margin forward to the anterior smooth covered zone, leaving between them broad rounded costae or keels. ‘The number of these costae is mostly fifteen of which the middorsal one is ordinarily much wider than the others. Scobina extending to the twenty seventh segment. The caudal plate does not cover the anal valves above, the latter protruding prominently. Number of segments, thirty-six or thirty-seven. Length of female, about 45 mm.; width, 4.6 mm.; depth,5 mm. Length of male, 19 mm.; width, 3 mm. This species is very close in its general appearance and structure to D. carinatus (Karsch). It may be distinguished at once in having the posterior margins of some of the segments distinctly sinuate above the scobina, the median region bulging convexly, and the costae or keels, which are low or flat, extending on the prozonites to the ante- rior region as well as across the metazonites. In the gonopods of the male the process of the median piece is narrower, more linear or but little spatulate in shape and is much longer in proportion to the basal piece which it exceeds in length. In the telopodite of the pos- terior gonopods the branches are very unequal, the exterior one the longer, weakly doubly curved, with the tip slightly expanded and blunt and bent; the lesser branch more slender, extending well beyond the middle of the principal one, pointed at tip. 2 ES —— COPEL A RAR Fg + RATS Ba i ; CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 199 580.

Lower ends with angles widely rounded but lateral margin somewhat flattened. The segments in general both below and on the sides and across the dorsum finely densely striate, the striae not so fine as, and the intervening ridges coarser than, in D. sericoides and allied species all of which have a silky lustre.

Anal scutum caudally rounded, exceeded by the valves. Valves moder- ately compressed, the inner borders not conspicuously upraised, Surface of valves and scutum with fine coriarious lines like those of the other segments. In the gonopods of the male the median piece has its basal part subtriangular with the distal tongue linear, rounded apically. In the telopodite of the posterior gonopods the two divisions are slender and nearly equal in length. Number of segments, forty-two. Length (female), to near 40 mm.; width, to 4.5 mm.

In the lower light region each segment is darker in front of the suture. Legs fulvous or tinged with ferruginous. Head with a dark angled area between the eyes. Sulcus interrupted in frontal region. Collum widely rounded below. Exceeded by the second tergite.

Z. 4,791. Paratypes.— M. C. Z. 4,792. Fijis: Nadarivatu (W. M. Mann). In coloration the pattern is similar, but the light marking on each side of the dorsum of each segment in D. leucopleurus has the part or spot on the prozonite obviously farther mesad than that on the metazonite, whereas the reverse relation of the spots holds in the present species; in leucopleurus also the anal tergite is black throughout excepting a narrow caudal marginal stripe, and in the present species the side of the tergite is fulvous or whitish in all specimens farther dorsad than the light lateral region of the other segments; and similarly the lateral region of the collum is conspicuously lighter, these large light areas on first and last segments forming a striking feature in the coloration of the species. The second tergite extends much farther below the collum than in leuco- pleurus. Number of segments, thirty-eight to forty-one. Diameter of female, up to 3.2 mm.; of the male, up to 2.8 mm. Very close to D. lewcopleurus in coloration, the sculpturing of the segments, in lacking scobina and in other features of general structure. In the gonopods of the male an easily detected difference is in the form of the median plate; in this the basal division is much larger, more strictly semicircular with the caudal margin much less obviously arcuate; whereas in D. leucopleurus the distal process is nearly parallel- sided except toward the tip, in the present species the process is strongly acuminate from its base to a narrow tip, the latter, however, rounded and not narrowing or itself acuminate; it equals the telo- podite, which in leucopleurus is shorter. In the posterior gonopods the lesser branch much shorter and more slender than the other, very closely appressed to it, a little divergent at tip. 584. DINEMATOCRICUS LEUCOPLEURUS, sp. nov.

Median plate of male gonopods formed much as in D. perstriatus; basal division nearly sublunate, its proximal margin arcuate and the lateral angles narrow, acute; distal process slender, narrowed at the tip which is acutely rounded, longer than the head division, but bent cephalad at tip as in per- striatus. In the telopodite of the posterior pair the branches are straighter, with the lesser one applied closely to the other, not divergent as in the other species. Number of segments, thirty-five to thirty-seven. Length (female), 27 mm.; width, 3.1 mm. This species is very similar to D. perstriatus in lacking scobina and in having segments closely, finely longitudinally striate above as well as laterally and below. It differs conspicuously in color, having the lower part of the sides and venter flavous, often of a brick-red cast, the intervening dorsal region greyish black, the prozonites being paler, and of a somewhat bluish cast; along each side of the dorsum a series of small pale spots, a series of light marks also at level of the pores, each mark being a light line from the pore along the longitudinal suture at its level.

From these species and D. holosericeus it is readily distinguished not only by the structure of the gonopods but also in having the caudal margin of some of the anterior segments sinuate over the scobina as in rex and undulatus. In the gonopods the median plate has the distal process longer and narrower than in others of the group with silky lustre mentioned above, and it is acutely pointed distad.

The male is larger and more robust, more nearly approaching the female in size. In the gonopods of the male the inner branch, while small, is a little longer than in the species mentioned and curves strongly mesad away from the outer branch.

Agreeing closely with D. fratrellus in coloration, proportions, number of somites, and form and distribution of scobina. It differs obviously in the impressions on the somites. The segmental suture is more deeply impressed, especially above; opposite the pore it is more widely and less strongly curved, the curve in D. fratrellus embracing the pore more closely above and extending farther cephalad before continuing in the straight dorsal part. Pore larger. The most readily noticeable difference is the presence on the prozonite dorsally of strong, somewhat sinuous transverse striae which bifurcate and unite sparsely and of which the most caudal, taking its origin just above anterior edge of pore, is typically deep and complete or sometimes interrupted, forming the so-called second suture. Number of segments, forty-eight. Length, about 46 mm.; width, 5.5 mm. 599. DINEMATOCRICUS RUBRIORIPES, sp. nov. “Typr.— M. C. Z. 4,941. Solomons: Wai-ai (W. M. Mann). This species also belongs in the D. fratrellus group which appears also to include biincisus (Pocock). It differs from D. fratrellus and impressior in having the legs ferruginous instead of brown. It differs from those species also in the course of the segmental suture which remains essentially straight or even bows a little in toward the pore instead of presenting a strong curve away from the pore; thus the pore lies wholly in front of the suture instead of being in line with its dorsal and ventral parts. Lacking the secondary suture character- istic of D. impressior. The type has forty-six somites as against forty-eight in the two preceding species. Length of type, about 43 mm.; width, 5mm. 600.

Lower margin very characteristic, the two sides straight, thickened and strongly chitinous, meeting in an obtuse angle in the middle whence they curve dorsad a little but form no distinctly set off median sinus; median teeth fused into a single plate crossing the angle. Antennae clavate, very short. Collum nearly attaining lower level of second tergite which is slightly con- cavely excavated beneath. Lower end of collum narrowly rounded. Suture of segments not strong, straight opposite the pore or sometimes widely curved. Caudal margin of tergites opposite pore often decidedly convexly bowed with an obtuse emargination part way down side from pore and sometimes one above pore. Dorsally the caudal margin also often obvi- ously sinuate. On the sides segments crossed by numerous very fine, closely arranged beaded striae which on prozonite tend to branch and to rise dorsad a little.

In P. pertinens (male) the second tergite extends rather more below level of collum than in the present form where it extends but slightly below it. In the present species the repugnatorial pores are situated notably farther dorsad; the suture is laterally more clearly impressed and runs closer to the pore which it touches, often curving a little about its upper portion so as to bring the dorsal part of suture in line with it whereas in the other species the pore is well removed. The striae of the lower and lateral region up to and a little above pore are similarly dense but they are finer, more lightly impressed, and in posterior region in particular may appear obscure toward and above the pore. .

It is more robust than P. pertinens, agreeing rather with waiainus in this regard. The pores, as with P. pertinens, are lower on the side than in waiainus. In P. pertinens also the suture does not curve at all about the pore, being essentially straight; but it is closer to the pore than in pertinens, or- dinarily coming in contact with its edge and often bending a little to- ward it. Striations of somites essentially as in the genotype. Most readily recognized by structure of the gonopods. The tongue of the anterior median plate is broader than in the genotype; it is similarly obtusely angulate on each side but is less narrowed distad, being somewhat intermediate in form between those of the two pre- ceding species.

Differing from Spirostrophus, e. g. in the gonopods of the male. In the anterior gonopods the anterior or coxal piece is elongate and nar- rowed distally to a slender cornuate process, whereas the distal or caudal division, also elongate, is distally broad and erect. In Spiro- strophus the coxal plate is distally much broader, exceeding in width the telopodite which, on the contrary, narrows to a slender cornuate process which curves mesad. The median plate has the distal or middle part much more elongate, not trapeziform, and distally acute.

In this species the median plate is most like that of Z. digitulus Brélemann in its form; the median process is similarly long but is less parallel-sided, narrowing moderately to a little beyond the middle and then a little widening into a somewhat spatulate end-region with acuminate tip; the outer (basal) lobe of each arm is much broader and projects more freely, the arch formed by the arms is rather longer with the arms less divergent above their bifurcation but similarly curling about the bases of the gonopods above. The coxal piece of the ante- rior gonopods distad of its middle narrowing to a slender process in line with its mesal border, the outer edge strongly sloping, the mesal continuing its even course, the process distally curving a little mesad. The telopodite is elongate and narrowed distad but is distally much broader than the anterior or basal segment, parallel sided, not acumi- nate as in Z. digitulus, barbed on ectal side near apex and again near middle of length. Posterior gonopod in general similar to that of Z. digitulus but much less deeply incised distally on ectal side. The prozonites vary from deep brown to black in color; the meta- zonites are red. Antennae and legs bright ferruginous. Anal seg- ment and the head and collum lighter, grey-brown, the collum margined with red. Sulcus of head distinct across vertex and below, absent from frontal region. Eyes trapeziform with the base caudad, the latter convex but other sides straight; somewhat less than twice their diameter apart; 6, 7, 7, 7, 6, 4, 3. The first four joints of the antennae are nearly glabrous, the fifth and especially the sixth hairy. Lower wing of collum with both the anterior and the caudal margin slanting to its angle; lower edge oblique, rising anterodorsad, a little incurved; margination as usual; surface strongly coriarious in its markings. Sutures well marked, straight, removed from the pore opposite which is not curved. On the anterior segments the prozo- nites are marked with transverse striae both above and below, longi- tudinal striae occurring only on the metazonites below, the latter above simply coriariously roughened. Farther caudad the prozonites are marked for some distance below the level of each pore with a series of striae rising obliquely from the suture and above the suture with a series of circular and horseshoe-shaped impressions on the line of the suture.

In the character of its gonopods approaching Z. digitulus (Bréle- mann) more nearly than ferruginopes, the genotype. The median plate has the sides more evenly curving; it is distally more prolonged and the tip is set off as a more slender process which equals or slightly surpasses the processes of the coxal plates. The narrowing distad of the coxal plate of the anterior gonopods is much less abrupt than in Z. digitulus. The distal part of the telopodite is broad, angular at apex and with an angular ectal projection nearly as in Z. digitulus. The general color is blue-black with the caudal borders of meta- zonites red; small black spots over part of the pores, labial border fulvous. Antennae and legs bright ferruginous. Head with sulcus, eyes, and antennae nearly as in Z. ferruginopes. Collum of male differing from that of the genotype in having the lower angle more acute, the lower margin evenly continuous with the anterior one. In the anterior region the segments are much as in the genotype, with transverse striae similarly developed but surface in general less roughened. On some of the anterior segments the prozonites are marked with curved crescentic to horseshoe-shaped marks which become smaller caudally, passing into small punctiform impressions. In the posterior region the segments above almost wholly smooth. The network of impressed lines on anal segment very fine and obscure. Scutum rounded, not surpassing the valves. The latter with mesal margins elevated. meng. CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 231 In the anterior legs of the male the coxal processes much less pointed than in Z. ferruginopes; those of the third legs narrowest, distally rounded; the following ones subquadrate in outline, being distally truncate. Number of segments, fifty-seven or fifty-eight. Diameter (male), 4.5 mm. 656. ZyYGOSTROPHUS URALLANUS, sp. nov. Typr.— M. C. Z. 4,799. Paratyprs.— M. C. Z. 4,800. New South Wales: Salisbury Court near Uralla (W. M. Wheeler). Presenting a very different appearance from the other species because of the broader and lighter pale stripes, each pale stripe, testaceous of a dilute ferruginous cast, embracing the entire meta- zonite and dorsally often encroaching on the prozonite; prozonite black, becoming lighter down the sides so that the pleural region appears lighter than the dorsum; covered zone also light colored. Anal segment, collum and head blackish or greyish black, the collum narrowly margined with the fulvoferruginous and the anal scutum and valves also paler caudally. Legs dilute ferruginous. Sulcus across vertex and below as usual. Vertex strongly, finely roughened with several impressions shagreened. Eyes more strongly narrowed cephalad than in Z. ferruginopes, fully twice their diameter apart. The lower edge of the collum short, rising obliquely and meeting the anterior edge at an angle as in Z. ferruginopes but a little convex, not incurved as in the latter form. Metazonites longitudinally striate below in the usual manner, these striae extending only half way up the side to the pore, above them a series of impressed areas along the suture. The prozonites on the side with a dense network of very fine curved lines, running obliquely or vertically; prozonites dorsally with numerous circular and _ horse- shoe-shaped impressions which decrease in size from the suture. Valves exceeding the anal tergite; mesal borders strongly elevated. In the gonopods the median plate has its distal piece formed pre- cisely as in Z. digitulus but proportionately longer and the sides not so strongly bulging at proximal end. The coxal plates of the anterior gonopods have the tips of their cornuate processes covered by the distal end of the median plate. The posterior or telopodite division of the anterior gonopods of a very different form, the distal end not 232 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. angular but truncate and expanded into a cap-like top; the lower ectal angular projection longer and more retrorse. The coxal processes of the third legs in the male clavately enlarged, the processes of the following legs small almost obsolete. Number of segments, fifty-five. Width of male type, 4.5 mm.

Locatiry.— Queensland: Cairns SYMPASTROPHUS, gen. nov. This genus is undoubtedly close to Spirostrophus with which it agrees, while differing from Trigoniulus, in lacking pads on the tarsi of the anterior feet of the males. It is segregated from Spirostrophus on the basis of differences in the male gonopods. The median plate of the gonopods is distally deeply incised. The anterior gonopods are especially characterized by having the femur extended into a con- spicuous process on the mesal side of a distinctly separated terminal joint, this process curving ectad. In the posterior gonopods below the ordinary processes there is a straight slender styliform process that seems to convey the seminal duct, though this is not wholly certain.

Posterior part of zonites red, the anterior region above brown to testaceous with a cross stripe, often interrupted at the middorsal line, dusky to black and the lower part of the sides and venter testaceous to fulvous. Anal scutum dark. Legs and antennae red. CHAMBERLIN: MYRIOPODA OF THE AUSTRALIAN REGION. 233 Head smooth. Sulcus widely interrupted in the frontal region. Antennae long, reaching to the caudal edge of the second tergite. Eyes large, only about their diameter apart. The cardo of the gnathochilarium much more strongly produced than in T'rigoniulus lumbricinus. Collum with lower angle more acute than in 7’. lumbricinus, its anterior edge straighter. Transverse sulcus curved at level of the pore. The principal markings of the segments dorsally are short, curved impressions in a band just in front of the position of the suture, these much fewer than in 7’. lwmbricinus and absent excepting in the narrow band mentioned, no coarse punctae. Segments strongly longitudinally striate beneath and part way up the side. Anal scutum smooth and shining, much exceeded by the valves. Valves with borders compressed and elevated but not set off by a marginal furrow; border crossed by distant fine sulci and also some fine vertical sulci across upper part of each valve. Median plate of gonopods with branches widely diverging, broad, curving about bases of gonopods as in Acanthiulus and Spirostrophus; mesal process or free portion of outer branch farther dorsad or toward end of arm than usual in Spirostrophus, broad and thin, short. Femur of anterior gonopods promi- nently ridged along mesal side and extended on this side distad as a conspicu- ous rounded prominence along the side of the tibial lobe toward which it eurves. The tibial lobe short, rounded, without angles or processes. In the posterior gonopods there is at the tip a triangular plate and below this a thin plate-like extension showing a median spine-like rib. From a rounded lobe proximad of this extends a slender acute needle or style which seems to con- tain the terminal part of the seminiferous duct but this could not be ascertained with entire certainty. Number of segments, fifty-four. Width, 4.5 mm. The following species were inadvertently omitted from the manu- script as prepared for publication. PLATYRRHACUS SARASINORUM Carl. Rev.

Tue following brief descriptions of certain new species of trilobites are abstracted from a larger manuscript, the publication of which has been postponed to allow the preparation of adequate illustrations. It has become necessary to use some of these names in another con- nection, hence this preliminary paper. TRINUCLEIDAE Emmrich. TRINUCLEUS ACERVULOSUS, sp. nov. Entire test flattened, subcircular in outline, cephalon twice as wide as long, with a narrow fringe. Glabella flask-shaped, narrow, bulbous in front, constricted to a narrow, low neck behind. There are three pairs of glabellar furrows beside the neck-furrow, two pairs showing as deep pits in the “neck,” and one pair as small indentations back of the middle of the ‘‘bulb.”” Fixed cheeks evenly convex, without eyes or eye-lines. Surface of glabella and cheeks reticulate. Fringe narrow, marked by radiating grooves separated by rounded ridges of about their own width. In the bottom of each groove are two pits, the anterior of which is the larger. At the genal angles the fringe widens and is marked by a number of irregularly placed, small pits. No specimen has been seen which retains genal spines, but they were undoubt- edly present, as there is a long spine on one of the slabs. Thorax of six narrow segments of the usual form in the family. Pygidium a little more than twice as wide as long, somewhat angular in outline on the posterior margin, nearly flat, with an abruptly deflected smooth border. Axial lobe narrow, not strongly elevated, with twelve to fifteen narrow rings separated by narrow, sharp furrows. Pleural lobes flat, with eight or nine pairs of ribs, each bearing a broad deep furrow. MeEAsuREMENTSs :— The holotype is 19 mm. long, 19 mm. wide at the genal angles; the cephalon 8 mm. long, thorax 5, and pygidium 6 mm. long. The bulb of the glabella is 5 mm. wide; the axial lobe of thorax 3 mm. wide; the pygidium 13 mm. wide. The fringe is 1 mm. wide, and there are twelve groovesin5 mm. Another specimen is 19 mm. long and 18 mm. wide, and a third 12.5 mm. long and 12 mm. wide. This species, the first American representative of the genus to be known from complete specimens, is more like Trinucleus diademata (Ruedemann) than any other allied form. Ruedemann’s species 274 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. from the boulders at Rysedorph Hill was described from an incom- plete cephalon, so that detailed comparison is not possible. It would appear, however, that our species has a narrower fringe-and less prominent glabella than specimens from the New York. Trinucleus fimbriatus Murchison, the type of the genus as restricted, is very similar to 7’. acervulosus, but differs in having more pits in the fringe, particularly at the genal angles. 7’. fimbriatus is probably from about the same horizon (Llandeilo) as our species. Horizon AnD Locauiry:— Numerous specimens have been collected by Prof. Roy Holdon from the Athens shale three miles northeast of Blacksburg, Va. Holotype M. C. Z. 1,592. DIONIDEIDAE, fam. nov. Dionideae Giirich, Centrabl. min. geol. pal., 1907, p. 135 (nomen nudum). Dionide has usually been placed with Trinucleus and Ampyx in the Trinucleidae. The structure is, however, not in accord with either of those genera and since they have been separated, Dionide can not logically be placed in either family. The free cheeks are ventral like those of the Trinucleidae but the cephalon does not have a regularly pitted brim and the pygidium is very large. The family may be diag- nosed as follows :— Isopygous hypoparia with six segments in the thorax and both shields large. Free cheeks ventral except for the genal spines. Surface of cephalon irregu- larly pitted. Hypostoma short, rounded, tuberculated. One genus, Dionide, Barrande. Ordovician, Europe and North America. DIONIDE HOLDONI, sp. nov. / Animal of medium size for the genus; test oval in outline, about one fifth longer than wide. Cephalon short, about three times as broad as long. Glabella relatively short, reaching only two thirds the length of the cephalon, moderately convex in outline, smooth except for the small median tubercle and a larger spine- base back of it. At the sides of the glabella there are faint indentations of a pair of lateral furrows, and at the back is a pair of short longitudinal ones. These latter are somewhat longer in young specimens than in the adults. Fixed cheeks depressed convex, covered with a fine network of irregular radi- Land RAYMOND: SOME NEW ORDOVICIAN TRILOBITES., 275 ating branching ridges and small shallow pits. The two principal “nervures”’ originate on either side of the glabella just in front of the lateral furrows and run diagonally backward, reaching the neck-furrow some distance inside the genal angles. Those on the right cheek of one specimen not only branch, but in the outer part of their course, the two unite, showing conclusively that they are not facial sutures. The cephalon has a narrow, upturned rim around its border, and in the concentric depression within this is a row of pits which are larger and deeper than the others on the cephalon. The neck-furrow is linear, clearly impressed and the neck-segment smooth. As usual in the genus, the facial suture is marginal except at the genal angles, where it cuts off the spines. These latter are not satisfactorily preserved on any specimens but apparently were not long enough to reach beyond the third thoracic seg- ment, a very unusual feature in this genus, and leading one to suspect that the specimens are incomplete in this regard. Thorax with six narrow segments, the first of which is a little wider than the succeeding ones, but not differently marked. Axial lobe narrow, each ring showing the diagonal furrow at the sides as is usual in the genus. The furrows on the pleural lobes divide each lateral portion of a segment into an anterior area which is pitted like the fixed cheeks, and a narrower smooth posterior part. The pygidium is about twice as wide as long, rounded in outline, with, in some cases, sufficient straightness of sides to produce a slight triangularity. Axial lobe narrow, with about fifteen rings, and pleural lobes with about twelve pairs of furrowed ribs which extend to the edge. Surface pitted, like that of fixed cheeks. MEASUREMENTS :— One specimen is 15.5 mm. long, 13 mm. wide at the genal angles. The pygidium is 5.5 mm. long, 11.5 mm. wide, thorax 4.5 mm. long, cephalon, 5.5mm. long. Another specimen is 15 mm. long, and 12.5 mm. wide. A third specimen is 19.5 mm. long, and 15 mm. wide. A cephalon is 6 mm. long and 18 mm. wide; distance from back to front of glabella, 4 mm., width of glabella 4.5 mm. This species is more like Dionide richardsoni Reed than any other known species of the genus. The likeness is emphasized particularly by the ornamentation of the thorax. It has, however, fewer rings and ribs on the pygidium, a wider cephalon and narrower axial lobe. The ornamentation of the thorax and pygidium separates it from all other species. Horizon anD Locarity:— This species has so far been found only at a locality about 100 feet below the top of the Athens shale about three miles northeast of Blacksburg, Va., where it was collected by Professor Holden, for whom it is named. The associated fossils are typical Normanskill graptolites, brachiopods, and trilobites. Holo- type M. C. Z. 1,590. 276 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. DIONIDE CONTRITA, Sp. noy. This species is represented by only a single specimen, a rather poor pygidium to which are attached parts of two segments of the thorax. It would not be worthy of description were it not for the fact that it belongs to the group with large pygidia. Cephalon not yet known. Thorax with narrow axial lobe and short segments, the outer ends of which turn backward. Pygidium large, nearly semicircular but not quite twice as wide as long. Axial lobe narrow, tapering gradually and regularly. The last four milli- meters of the axis are broken off, but the anterior part shows eighteen rings, and there were apparently about twenty-four pairs of ribs on the pleural lobes, these being especially crowded at the posterior end. MeasurEMENTS:— Length of pygidium, 14.5 mm., width about 24 mm. The axial lobe is 5 mm. wide at the front. Horizon AnD Locatiry:— The only known specimen was collected by the writer about 100 feet above the bottom of the Athens shale near the Thomas farm three miles northeast of Blacksburg, Va. Holo- type M. C. Z. 1,591. ’ . RAPHIOPHORIDAE Angelin. RAPHIOPHORUS POWELLI, sp. nov. Entire test broadly oval, nearly as wide as long. Cranidium approximately semicircular in outline, the glabella projecting slightly in front of the cheeks. Glabella obovate, prominently convex, with a small spine directed forward and upward. At the base of the glabella there are two small narrow lobes, cut off by the posterior glabellar furrows. Fixed cheeks depressed convex. Free cheeks missing, but evidently narrow. Thorax with five segments, each pleuron bearing a deep linear, straight, median groove. Pygidium short and wide, with abruptly deflected posterior border. The pleural lobes bear two pairs of faintly defined ribs which curve backward to the margin. MerASUREMENTS:— Length, 10.5 mm., width 9 mm. Length cephalon 5mm., width9 mm. Width glabella at front, 3 mm., at back 2mm., Length thorax 2.5 mm., width axial lobe 2mm. Length pygidium, 2.5 mm. (circa), width 8 mm. This species most nearly resembles R. semicostatus, differing only in having a less rapidly expanding glabella, in the presence of glabellar RAYMOND: SOME NEW ORDOVICIAN TRILOBITES. 277 lobes, and in the pygidium, which has fewer and curved, instead of straight, ribs. Horizon AND Locatity:— Aside from the typical region, the Catawba Valley, Va., I have also found this species at Saltville, in the lower part of the Athens, and in yellowish calcareous shales near the railroad station at Bull’s Gap, Tenn. Holotype 1,598 M. C. Z. Paratype M. C. Z. 1,599. ENDYMIONIIDAE, fam. nov. This family is erected for species which resemble the Raphiophoridae in the possession of narrow free cheeks without eyes, and a short Ampyx-like pygidium, but lack a glabellar spine. The typical genus is Endymionia. The family may be briefly characterized as follows :— Hypoparia with narrow dorsal free cheeks but no eyes, no glabellar spine, seven segments in the thorax, short ampycid pygidium. Ordovician, Quebec, Newfoundland, Scotland, and Sweden. EnpyYMioniA Billings. Cephalon evenly convex with large glabella divided into three parts by a pair of longitudinal furrows. Axial lobe of thorax about one third the total width. Type, Endymionia meeki Billings. Lower and Lower Middle Ordovician, Quebec, and Newfoundland. ANISONOTUS, gen. nov. Cephalon irregularly convex, glabella small, with lateral furrows indicated by pits. Axial lobe of thorax narrow. Type, Shumardia glacialis Billings. Lower and Lower Middle Ordovician, Newfoundland, Scotland, Sweden. Other species which appear to belong to this genus are Anisonotus hornet (Nicholson and Etheridge) from the Balclatchie (Llandeilo) of Scotland and A. obtusus (Moberg and Segerberg) from the Ceratopyge shales of Sweden. ENDYMIONIA SCHUCHERTI, sp. nov. Endymionia meeki Billings (partim). Palaeozoic foss. Canada, 1865, 1, p. 281. Specimens of this species are larger than those of EF. meeki, with smooth rather evenly convex cephalon, and flattened thorax and pygidium. Lengths of cephalon, thorax, and pygidium in the proportion 2 : 2 : 1. 278 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. Cranidium a little more than twice as wide as long, smooth, gently and evenly convex. Glabella very large, depressed convex, with large lateral lobes strongly suggestive of Amphilichas. The outline of the whole glabella is roughly circular, the width being a little greater than the length of the glabella and neck-ring. The confluent glabellar furrows follow exactly the same course as do those of an Amphilichas, separating large, oval, diagonally placed lateral lobes. The central lobe is narrowest a short distance in front of the neck-furrow, and widest at the front. In front of the glabella the cheek slopes down to a very narrow flattened or concave border which is absent from the sides, where narrow, free cheeks extending back to the genal angles and probably elongated into genal spines were probably present. No evidence of the presence of eyes remains, and it is probable that like the Raphiophoridae these were blind trilobites with dorsal facial sutures. The neck-furrow is distinct all across the back of the cephalon, but narrow. The neck-segment is wider near the distal ends than near the axial lobe. The thorax has seven narrow segments, the axial lobe being gently convex and the pleural lobes flat. The axial lobe is rather wide, nearly one third the total width and tapers very little from front to back. On the pleural lobe each segment shows a rather wide, deep, central furrow. The pygidium is short, Ampyx-like, with four rings on the wide axial lobe and three pairs of ribs on the pleural lobes, and is surrounded by a steeply sloping striated border. M®e8ASUREMENTS :— Entire specimen; length, 10 mm., width at genal angles, 9 mm.; length cephalon, 4 mm., thorax 4 mm., pygidium 2 mm., width glabella 3.75 mm., width axial lobe at front of thorax 2.5 mm., at front of pygidium 2 mm., width pygidium at front 6.5mm. Largest cranidium, length 9 mm., width 15 mm., width glabella 8 mm., length glabella 7.5 mm. This species is very like E. meeki, and I should not have been able to separate the two had not specimens of both been before me. In E. schucherti the glabella is more nearly circular in outline, broader, and flatter than in /. meeki, and the median tubercle is fainter and farther forward, so faint in fact as to be invisible on most specimens. In E. meeki there is a strongly striated abruptly sloping border in front of the glabella while in FE. schucherti the corresponding portion is a smooth “roll” sloping down to a narrow concave border. Horizon AND Locauiry:— Professors Schuchert and Twenhofel collected twelve specimens, three of them entire, from the limestones of Division N, (Normanskill) at Table Head, Newfoundland. Billings referred to this form as occurring abundantly in Division N at Table Head and the west side of Pistolet Bay, also in Division P, four miles northeast from Portland Creek, Newfoundland. The types are in the Yale University Museum. Named for Prof. Charles Schuchert. RAYMOND: SOME NEW ORDOVICIAN TRILOBITES. 279 ANISONOTUS, gen. nov. ANISONOTUS GLACIALIS (Billings). Shumardia glacialis Billings, Palaeozoic foss. Canada, 1865, 1, p. 238, fig. 270. Entire trilobite oval in outline, nearly as wide as long, the greatest width being at the back of the cephalon. The cephalon is strongly convex; the thorax and pygidium nearly flat except for the axial lobe, which is narrow and elevated, The cephalon is trinuclear, the swollen glabella rising above the mound-like fixed cheeks. The glabella extends two thirds of the length of the cephalon (measured on the curvature) and shows at the sides four pairs of pits. The last pair represent the neck-furrow, and the others the fourth, third, and second pairs of glabellar furrows. The first and fourth pairs of pits are much less con- spicuous than the others. The elevated glabella is bounded by a pair of narrow furrows which converge backward and outside these is a pair of furrows which are parallel to the axis of the head. Between the parallel and the con- verging furrows are a pair of only slightly elevated triangular ridges, the apices pointed forward. Outside the parallel furrows on the cephalon there are two evenly rounded mounds, limited on the inside and back by straight furrows intersecting at right angles and at the front by a curving depression which joins the dorsal furrows opposite the anterior glabellar furrows. In this depression there is on each side a narrow but distinct eye-line which curves backward around the mound and continues to the border of the cheek, meeting it at the horizon of the neck-furrow. In front of this furrow and in front of the glabella there is a rather abrupt bulging slope to the margin, which appears to be somewhat thickened, but probably without rim or brim. The type being exfoliated, gives the appearance of a very narrow brim on the front. At the genal angles the fixed cheeks are drawn back into short lapets which extend behind the neck-ring. These lapets are semicircular in outline, and it is difficult to decide whether they are the actual genal angles, or whether they were enveloped by spines belonging to the free cheeks. In front of the angles there is a slight sinuosity in the side of the cheek, and along this part the border which is present on the front of the cephalon is absent. This seems to indicate that free cheeks should be present, but very narrow ones as in most species of Ampyx. ‘These cheeks would probably have borne the genal spines. The anterior portion of the cephalon is covered with very fine wavy lines parallel to the anterior edge. The thorax has seven segments, and does not taper from front to back. The axial lobe is narrow, one fifth of the total width, and strongly elevated. The pleural lobes are flat, each pleuron bearing a linear groove whose course is at right angles to the axis. The first two segments do not extend quite so 280 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. far at the sides as those behind — a common condition in trilobites with genal spines. The pygidium .«s nearly semicircular, but has the somewhat triangular appearance so often seen in pygidia of ampycids or trinucleids. The axial lobe is narrow, elevated, and extends almost to the posterior border. The pleural lobes are flat, and turn down but little to the very narrow thickened margin. Singularly enough, there is a ring on the axial lobe for each pair of ribs on the pleural lobes, so that rings and ribs are continuous. Nine dis- tinct rings are present. ‘The ribs are narrow and flat, with just a suggestion of an impressed line along the top. MEASUREMENTS:— Length 14.5 mm., greatest width, 13 mm., width at middle of thorax, 10.5 mm. Length of cephalon 6.5 mm., width 13 mm.; length glabella 4.5 mm., width of glabella at front 3.25mm. Length of thorax 4 mm., width 10.5 mm.; width of axial lobe 2 mm. Length of pygidium 3.25 mm., width at front 9 mm.; width of axial lobe at front 1.5mm. A flat- tened cephalon is 6 mm. long, 15 mm. wide, and the glabella is 4.5 mm. long. This species differs in many respects from Endymionia meeki. The glabella is shorter and considerably narrower, has four instead of two pairs of pits at the sides, and has much less prominent lobes beside it. E. meeki does not seem to have the mound-like cheeks, and eye-lines are absent. The axial lobe of the thorax is much narrower in A. glacialis than in E. meeki, and the furrows on the pleura are straight instead of sinuous. The pygidium of the present species has a nar- rower axial lobe and more rings and ribs than in the Beekmantown form. With the knowledge of this specimen it is possible to get a better idea of the characteristics of the Endymionidae. The form of the thorax and pygidium and the presence of narrow free cheeks approach very closely to the Raphiophoridae, being excluded from that family as now defined only by the shortness of the glabella and the absence of a long spine therefrom. Horizon anpd Locatiry:— Billings’s specimens came from the conglomerates of Portland Creek and Pistolet Bay, Newfoundland. Hyatt found it on the east side at Port au Port, and Schuchert and Twenhofel obtained three fragments from the same locality. The horizon is their zone 6, Normanskill. Genoholotype M. C. Z. 1,594. OLENIDAE Burmeister. TRIARTHRUS CAECIGENUS, Sp. Nov. Entire test oval, of the usual shape in this genus, without spines or pustules except for a small one on the neck-ring. RAYMOND: SOME NEW ORDOVICIAN TRILOBITES. 281 Cephalon somewhat irregular in outline, the glabella projecting in front of the cheeks. Glabella long and wide, with a very narrow circumglabellar fur- row and a very narrow upturned border. There are two pairs of glabellar furrows which run inward and somewhat backward and are deeply impressed, particularly at their inner ends. Fixed cheeks narrow, with a somewhat wide convex marginal border which extends around the sides and connects with the neck-ring. A truncation of this border at the sides suggests the possible former presence of very narrow free cheeks, but there are no traces of palpe- bral lobes. Thorax with (apparently) eleven segments. Axial lobe wide and the rings smooth. Pygidium strongly segmented, with about six pairs of ribs on the pleural lobes and seven rings on the axial lobe. MerasureMENTS:— Length, 11.5 mm. Length cephalon, 3.5 mm., thorax, 5.5 mm., pygidium, 3 mm. Width at genal angles, 6 mm., width glabella, 3 mm., width axial lobe at front 2.75 mm., width pygidium 4 mm. This species can be distinguished from all others by the absence of eyes. The most closely allied species is Triarthrus humilis Hadding which has the eyes far forward and the free cheeks very narrow. Horizon anp Locauiry:— A rather common species in the Athens shale in the Catawba valley north of Salem, Va., where the type was collected by Prof. S. L. Powell, and also at Laskers Gate, three miles northeast of Blacksburg, Va., where it was collected by Dr. R. M. Field and the writer. A few specimens were also found at Saltville, Va., near the base of the Athens. Holotype M. C. Z. 1,593. REMOPLEURIDAE Corda. ROBERGIA MAJOR, sp. Nov. Cephalon large, rounded in front, wider than long, with long narrow spines at the genal angles. Glabella elongate, a little expanded in front of the long eyes, with three pairs of furrows on the wide portion between the eyes. In front of the glabella there is an extremely narrow flattened border. Free cheek narrow, extended backward into a narrow spine of about its own length. Hypostoma bifurcated, with two very long prongs, as in Remopleurides. Thorax known from two incomplete specimens, the larger with nine seg- ments. Judging from these specimens the thorax is long, narrow, with very little taper. The axial lobe is wide, convex; the side lobes flat and narrow, the individual segments ending in short spines. Pygidium nearly square, as long as wide, sides straight and slightly con- vergent. Axial lobe elevated, extending three fourths of the length, wide 282 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. at the front, tapering regularly backward. ‘There are four well-marked rings. Pleural lobes practically flat, apparently crossed by obscure ribs, but all specimens are exfoliated, showing a wide striated doublure. The posterior margin shows two pairs of short flat spines, the inner ones being wider than the outer, and extending practically as far back. MeraAsuREMENTS:— A large cranidium is 15.5 mm. long, and 15 mm. wide at the palpebral lobes. Nine segments of a thorax are 7.5 mm. long, 4 mm. wide at the anterior end and 3.5 mm. wide at the posterior. The axial lobe is 2.5 mm. wide at the front. A pygidium is 10 mm. long, 10 mm. wide at the anterior end and 9 mm. wide at the posterior end. The axial lobe is 5 mm. wide at the anterior end and 7.5 mm. long. This species is exceedingly abundant in the Athens at Saltville, Va., and though no complete specimens have so far been found, it is now known from all the parts, including the hypostome, which can- not be said of any other species of the genus. It differs but little from Robergia schlotheimi, such differences as there are being in the pygidium, which has a longer and wider axial lobe, is more nearly square, and has a straighter posterior margin. It differs from the Swedish R. micropthalma chiefly in the pygidium which is much more nearly square and has two instead of three pairs of spines. Horizon anp Locatiry:— A very abundant species in the lower part of the Athens at Saltville, Va., but not yet found elsewhere. Cotypes M. C. Z. 1,601 to 1,606. STYGINIDAE, fam. nov. Approximately isopygous Opisthoparia with glabella greatly expanded at the front, anterior portions of the facial sutures widely divergent, eyes typically very far back. Thorax of nine segments in the typical genus. Pygid- ium with well-defined, long axial lobe, pleural lobes smooth or with faint furrows. Srycina Salter. Glabella only faintly outlined, without furrows. Eyes close to posterior margin. Type, Stygina latifrons (Portlock). Ordovician, Scandinavia, and British Isles. Bronteopsis Nicholson and Etheridge.

Holometopus angelini Billings (partim), Palaeozoic foss. Canada, 1865, 1, p. 281. Non, p. 95, fig. 85. Cranidium much expanded at the front, so that it is wider than long. Gla- bella convex, prominent, expanded at the anterior end, the width there being equal to about three fourths the length. The glabella tapers rapidly toward the narrowest place, at the neck-ring, and has an obscure median carina on its posterior half. In the dorsal furrows are obscure indications of three pairs of pits, one pair close to the anterior margin and two pairs on the constricted “neck” of the glabella, these being obscure glabellar furrows. The fixed cheeks form wide flattened bands on either side of the glabella and opposite its narrow part, are raised nearly or quite as high as the glabella itself. The neck-ring bears a small median tubercle. Pygidium approximately semicircular in outline, convex, with a narrow coneave border. Axial lobe long, the acutely tapering posterior end continu- ing though only faintly raised, to the border. At the anterior end of the axial lobe are three well-defined rings, behind which there are two or three rather obscure ones. The pleural lobes are smooth, except for an anterior rib. The smaller specimens are nearly flat, and the posterior portion of the axial lobe more clearly defined than in the large ones. M®EASUREMENTS:— Length cranidium, 7.5 mm., width at front, 9 mm. Width glabella at front, 5.5 mm., at neck furrow, 3.5mm. Length pygidium 4 mm., width, 7.5 mm. Horizon AND Loca.ity:— The types are from the base of the Liberty Hall limestone at Lexington, Va., where the species is common. It is also common at the top of the Holston at the Thomas farm, three miles northeast of Blacksburg, Va., and in the Athens at Chatham Hill, on the northern slope of Walker Mountain, north of Marion, Va. A single specimen was found above the middle of the Holston on the Hoge farm seven miles south of Bland, Bland Co., Va., and another single specimen in the middle Ottosee, seven miles north of Mendota. Specimens from these three localities are in entire agreement. In Tennessee I found it at only one locality, between the Holston and Tellico, in South Knoxville. 284 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. In Newfoundland Schuchert and Twenhofel found this species in zones Ms, N,, and the Isolated limestone, all at Table Head. These specimens differ from the ones described above in having the crani- dium a little shorter and broader, the posterior part of the glabella a little wider, and a slightly shorter axial lobe on the pygidium. Specimens nearer these than the other Virginian specimens were collected by Dr. Shuler on the northern side of Walker Mountain near White Gate, Bland Co., Va. This species is much more nearly related to Bronteopsis ardmilla- nensis Reed, than to the type of the genus. The Scottish species has a slightly different conformation of the fixed cheeks and more traces of ribs on the pleural lobes of the pygidium, but the differences between the two species are small. B. nitens Wiman, obtained from boulders of the older Chasmops limestone, has a somewhat wider glabella and a more acutely triangular axial lobe on the pygidium than our species. Cotypes M. C.

While evidently closely allied to Nileus, this species differs from all other species of that genus in having the eyes relatively small and particularly in having them very far back. Another peculiarity is the strong development of the verti- cal suture on the doublure. I have examined with care great num- bers of specimens of Nileus from Norway and Sweden without ever finding this suture, nor does it show in any of the American speci- mens. The strong development in Nileoides perkinsi is therefore of considerable importance. Cephalon Nileus-like, glabella not outlined, cranidium smooth, gently convex, elongate, not abruptly inflected in front of the eyes. Eyes large, but not so large in proportion to the length of the cephalon as in Nileus. — Vertical suture present. Axial lobe of thorax wide. Type, Nileus perkinst Raymond. Upper Chazy, Vermont. RAYMOND: SOME NEW ORDOVICIAN TRILOBITES. 285 HyBoasPIs gen. noy. This name is proposed for a curious trilobite in the pygidium of which are combined the elongate form of the asaphid and the short axial lobe of the illaenid. I know of no asaphid with short axial lobe on the pygidium and only in Actinolobus among the Illaenidae is there any hint of elongation of the pygidium and even there nothing comparable to what is seen in the form now to be described. While the ascription of the genus to either the Asaphidae or Illaenidae can- not positively be made until the cephalon is found, I have for the present placed. it with the Asaphidae. HYBOASPIS SHULERI, sp. noy. Cephalon and thorax unknown. Pygidium elongate, narrow, highly convex, turned up somewhat at the pos- terior end. Axial lobe low, not sharply outlined, without rings, a trifle more than one third the total length. Pleural lobes steep-sided, with narrow con- cave border, which does not extend around the posterior end. No traces of ribs, except for the anterior one. Surface of pleural and axial lobes crossed by wavy cracks which have a course approximately at right angles to the axis. Doublure wide, especially at the posterior, where it extends halfway to the front, and marked by strong but widely separated terrace lines. MerASUREMENTS:— The largest pygidium is 73 mm. long and about 56 mm. wide. The smallest is 22 mm. long and 21 mm. wide. In the large specimen the axial lobe is 25 mm. long. In the small one it is 8 mm. in length. I know of no trilobite with which this can be compared. Horizon anp Locautiry:— Only three pygidia of this species have so far been found, two by Dr. E. W.

Carnegie mus., 1910, 7, no. 1, p. 51; Raymond, [bidem, p. 63) to an American trilobite by Raymond and Narraway in describing a new species from 286 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. the Middle Ordovician of Minnesota and Pennsylvania. ‘The essen- tial features of the trilobites for which this name has been used are the isoteliform glabella and sutures, but asaphiform lack of concave borders on the shields. Since my attention was first directed to this combination of characteristics wider experience has shown that they form a large group in the Middle and Upper Ordovician and that while similar to the Russian Onchometopus they are probably not congeneric with it. The two genera form one more example of that “Parallelism among the Asaphidae” to which I have already called attention (Trans. Royal soc. Canada, 1912, 5, sect. 4, p. 111). De- tailed study with large numbers of specimens indicates that Oncho- metopus is a derivative of Asaphus, while Homotelus sprang from Isotelus, not once merely, but probably several times. Homotelus differs from Isotelus chiefly in lacking the concave borders on the shields. Often specimens are found in which concave borders are feebly or sometimes even well developed, indicating that this char- acteristic is one of suppression and showing readily how a Homotelus could have been evolved time after time from various species of Isotelus. Homotelus cannot then be regarded in a strict sense as a good genus, but is a convenient term for a number of species showing similar characteristics. At the time of our first use of Onchometopus, Mr. Narraway and I pointed out that the American species which we referred to the genus did not have the peculiar hooked doublure which Schmidt consid- ered the most important feature. In 1914 it was my privilege, aided by the Shaler Memorial fund, to collect Onchometopus from the typical localities south of Lake Ladoga, and direct comparison of specimens is now possible. Cephala of American and Russian forms are exceedingly alike in smoothness of glabella, position of eyes, course of facial sutures, and shape of fixed and free cheeks. Doublures are strikingly different not only in the hooked and furrowed character — of the Russian form, but also in its narrowness. Greater differences are seen in the thorax, where Onchometopus shows the high narrow rings of an Asaphus while the Homotelus has the broader and flat- tened rings of the Isotelus. The pygidia again are similar but that of Onchometopus is generally shorter and more nearly semicircular. As the type of Homotelus I am selecting a species from the Eden of the region of Cincinnati, chosen because of the excellent material available, and named Homotelus ulrichi for Dr. E. O. Ulrich of the U. 5. Geological Survey. RAYMOND: SOME NEW ORDOVICIAN TRILOBITES. 287 Homore.us ULRICHI, sp. nov. Outline of entire animal oval, whole surface rather evenly convex, the eyes being the only conspicuous prominences. Cephalon and pygidium about equal. ‘ephalon twice as wide as long, nearly semicircular, but since the outline comes just within the semicircle passing through the anterior point and genal angles there is a suggestion of triangularity. The glabella is smooth, not differentiated. On an occasional specimen there are two pairs of pits between the eyes, the vestiges of two pairs of glabellar furrows. The neck-furrow is practically obsolete and just in front of its normal position is a very small median pustule. The dorsal furrows are very faint except on crushed speci- mens. The eyes are small, strongly elevated and far apart. The palpebral lobes are small, concave on top and so short that a part of the visual surface looks upward. The genal angles are rounded and the sides of the cheeks have a narrow flattened and striated border which stands at an angle with the general surface and is turned downward at the sides and front. This joins the nearly horizontal doublure in a sharp edge. Axial lobe of thorax wide, but less than one half the entire width. Pygidium not quite twice as wide as long, the narrow axial lobe faintly but definitely outlined, most prominent at the posterior end. Pleural lobes smooth. MEASUREMENTS :— The entire specimen selected as the type is 58 mm. long and 33 mm. wide at the genal angles. The cephalon is 18.5 mm. long, the eye 5 mm. long, and the back of the eye 6 mm. from the posterior margin of the head. The thorax is 20 mm. long, 32 mm. wide at front and 32 mm. wide at back. The axial lobe is 15 mm. wide at front and 13.5 mm. wide at back. The pygidium is 19.5 mm. long, 32 mm. wide at the front. The axial lobe is 15 mm. long. Homotelus obtusus (Hall) of the Chazy differs from this species in having more strongly impressed furrows and particularly in its very conspicuously punctate shell. Homotelus simplex (Narraway and Raymond) is much more closely like the present one but has the eyes larger and further back, more traces of ribs on the pygidium, and lacks the angulated border on the cephalon. Horizon anp Loca.ity:— This species seems to be quite common in the Eden in the vicinity of Cincinnati, Ohio, but as the specimens are all in the Dyer collection I have no data on either exact horizon or locality.

Onchometopus simplex Bassler (non Raymond and Narraway), Maryland geol. sur., Cambrian and Ordovician, 1919, p. 348, pl. 47, fig. 11. Test large for the genus, elongate, both shields subtriangular, strongly convex. Cephalon subtriangular, less than twice as wide as long, evenly convex. Glabella smooth, not outlined, dorsal furrows present only back of the eyes and glabellar furrows obsolete. Eyes prominent, situated a little back of the middle but more than their length ahead of the posterior margin. Genal angles rounded. Thorax abruptly deflected at the sides, depressed convex on top. Axial lobe less than one half the total width. Pygidium triangular, strongly and evenly convex, the axial lobe hardly outlined except at the posterior end. Exfoliated specimens show traces of several ribs on the pleural lobes. MEASUREMENTS :— One entire but much damaged specimen is about 105 mm. long and 60 mm. wide at the genal angles. A well-preserved pygidium is 44 mm. long and 63 mm. wide. A smaller one is 36 mm. long and 51 mm. wide. This species is readily recognized by its highly convex triangular shields. The axial lobe of the pygidium is also less strongly defined than in most other species.

This species is so far represented only by pygidia but these differ obviously from the majority of species of the genus in their more elongate form and the upturned posterior border. The axial lobe is long, narrow, gently tapering, and prominent. The pleural lobes ribless, evenly convex. Back of the axial lobe the posterior margin is upturned, so that in this region there is a concave border. This upward tilt in the posterior margin suggests a somewhat pointed cephalon. The surface of the test is covered with small flat-bottomed circular depressions which are arranged about as closely together RAYMOND: SOME NEW ORDOVICIAN TRILOBITES. 289 as they can be and still retain their circular shape. They appear to be very large but superficial puncta. Along the borders these are less numerous, and among them are numbers of short wavy cracks roughly parallel to the margin. Exfoliated specimens of course show no trace of this ornamentation but do show faint traces of ribs on the pleural lobes. MeaAsuREMENTS:— The largest pygidium is 43 mm. long and 57 mm. wide. The axial lobe is 35 mm. long and 17 mm. wide at the front. A second speci- men is 33 mm. long and 45 mm. wide. The ratio of length to width indicates the elongation of the pygidium in this species. This index in H. ulrichi which is more like H. indentus than any other described species is about 610, in H. obtusus it is 655 to 680, in H. elongatus, which has a long pygidium it is about 700, while in the largest specimen of H. indentus it is 754. Aside from the length of the pygidium and the upturned posterior margin, the character of the ornamentation serves to identify this species. if Horizon AND Lovatiry:— This seems to be a rather rare species, found so far only in the Holston in the Catawba Valley, north of Salem, and on the Hoge farm, nine miles southwest of Bland, Va. The specimens from this latter locality were collected by Dr. E. W. Shuler. Cotypes M. C. Z. 1,581, 1,582. HoMOTELUS LAEVIS, sp. nov. This name is suggested for a species, the pygidia of which are com- mon and of which a few fragmentary cranidia and free cheeks have been seen. In general outline and proportions the pygidium is most like that of H. obtusus but the axial lobe is more strongly developed and the puncta are much fewer, finer, and farther apart. There is also a faint concave border on the posterior part. The cranidium is very slightly convex, the eyes large and well back. The cephalon is in fact much more typically isoteliform than that of any other species. Exfoliated or compressed specimens show rather plainly the ribs of the pygidium. MEASUREMENTS :— A small pygidium is 22 mm. long and about 35 mm. wide. The axial lobe is 16 mm. long and 11 mm. wide at the front. A large speci- men (flattened) is 45 mm. long and about 70 mm. wide. This species is exceedingly common in the Athens at Chatham Hill, on the northern slope of Walker Mountain, north of Marion, Va. It is 290, BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. also found in the same formation near White Gate and Tilsons Gap, Bland Co., and in the Holston near McDonalds Mills in the Catawba Valley, north of Salem, Va., in all of which localities it was collected by Dr. E. W. Shuler; and also in the Holston at the McNutt quarry, Sharon Springs, Va. A single large pygidium collected by the writer in the Athens near Saltville, Va., is probably of this same species. In the lower part of the Athens near Bull’s Gap, Tenn., the species is quite common. Holotype M. C. Z. 1,600. HOMOTELUS LAEVIURUS, sp. nov. This species has a short broad cranidium, of little convexity, on which the glabella is entirely merged into the general surface, and dorsal and glabellar furrows quite absent. ‘The median pustule is small but prominent on the otherwise smooth surface, and the shell seems devoid of puncta. The free cheeks and thorax are unknown. The pygidium is evenly convex and the only marking is a very slight swelling indicating the position of the posterior end of the axial lobe. Even in internal casts the outline of the axial lobe shows only vaguely. M®rASUREMENTS :— A cranidium is 17 mm. long and 24 mm. wide at the tips of the fixed cheeks. At the widest point in front of the eyes it is 16 mm. wide. Another cranidium is 11.5 mm. long, 16 mm. wide at the tips of the fixed cheeks, and 9.5 mm. wide at the palpebral lobes. A pygidium is 14 mm. long and 19 mm. wide. This species is more nearly allied to Homotelus simplex Raymond and Narraway than to any other described speciés, but has smoother shields, and the pygidium in particular shows less trace of the axial lobe. The absence of puncta in the shell separate it from H. obtusus, the only other species with which it could be confused.

The only representative of this genus so far found on Newfoundland is a single cranidium which does not seem referable to any of the described species. RAYMOND: SOME NEW ORDOVICIAN TRILOBITES, 291 This specimen indicates a short and wide cephalon which was evenly arched and rather convex for the genus. The glabella is merged com- pletely into the general surface, and both dorsal and glabellar furrows are completely absent. The facial sutures turn far outward in front of the eyes, so that this portion of the cranidium is wider than in any other species of the genus. The palpebral lobes are large, indicating very large eyes, and are situated a little more than their own length in front of the posterior margin, but not quite twice their length from the anterior edge. The surface, so far as can be determined from a largely exfoliated specimen, is smooth. This species differs from any previously described, in having larger eyes and in the greater width of the portion of the cranidium in front of them. MEASUREMENTS :— Length of cranidium, about 32 mm., width at palpebral lobes, 32mm. Length of palpebral lobe, 8 mm., distance from back of palpe- bral lobe to posterior margin, 11 mm. The single specimen was collected by Professor Dunbar from a pebble in the Cow Head conglomerate on Stearing Island, Newfound- land, and is in the Yale University Museum.

Although proposed as a subgenus of Nileus, Vogdesia proves to be one of the Asaphinae, and closely related to Homotelus and Brachyas- pis. ‘This conclusion has been reached from a study of the dorsal surface, as the hypostoma has not yet been seen. Vogdesia differs from both the genera mentioned in having a wider axial lobe in the thorax, and little or no trace of dorsal furrows on the pygidium. The type is Vogdesia bearsi Raymond, from the Chazy. Other species are Vogdesia minnesotensis (Foerste) and Nileus sp. (Foerste, Bull.

M®EASUREMENTS:— Specimen, if extended, about 120 mm. long. The cephalon is 34 mm. long and 58 mm. wide; an eye is 8 mm. long and 8 mm. from the posterior margin. The pygidium is 36 mm. long and 55 mm. wide, with no trace of an axial lobe. The thorax is estimated to be about 50 mm. long, each of the eight segments being 7 mm. wide in the enrolled state.

RAYMOND: SOME NEW ORDOVICIAN TRILOBITES., 293 Several years ago Mr. A. G. Becker, while collecting in the ravine of a small stream about two miles west of Clermont, lowa, came upon a slab of limestone on which were two specimens of the trilobite which Slocum later described as Megalaspis beckeri. The outstanding feature of this animal is the great elongation of the anterior portion of the cephalon. The elongate triangular head-shield invited a comparison with such asaphids as Megalaspis extenuata (Dalman), hence the generic reference. No one has as yet been fortunate enough to discover an hypostoma of this species, so that it is not possible to say definitely that M. beckeri is not a Megalaspis, but that it is almost certainly not one is indicated by the following considerations :— 1st. Nearly all the species of Megalaspis in the typical region in northern Europe are found in the Lower Ordovician, only one or two surviving till the Middle Ordovician, and none till the Upper Ordovi- cian rocks were deposited. 2nd. Megalaspis is exceedingly rare in America, while isotelids are common and highly variable. 3rd. No hypostoma of the ogygiocarinid type has been found in the Maquoketa. 4th. The glabella of Megalaspis beckeri is not definitely outlined and is long, while in all species of the true Megalaspis the glabella is outlined and is relatively short. 5th. ‘The axial lobe of the thorax of M. beckeri is wider in propor- tion to the total width than is that of any species of the true Mega- laspis. In consideration of the above, I make Megalaspis beckeri the type of a new genus, Ectenaspis, the extended or stretched out character of the cephalic shield suggesting the name. This genus seems very close to Isotelus, and its derivation from Isoteloides through some such forms as I. angusticaudus Raymond and Ectenaspis homalono- toides (Walcott) is quite probable. Ectenaspis beckeri is an exceedingly rare fossil in the lower part of the Maquoketa (Upper Ordovician) in Fayette Co., Iowa. The only other species which can now be placed in this genus is Ectenaspis homalonotoides (Walcott). ISOTELUS ANNECTANS sp. nov. Tsoteloides homalonotoides Raymond and Narraway (non Walcott), Ann. Carnegie museum, 1910, 7, p. 52, pl. 16, figs. 9-11. 294 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. This name is proposed for the species previously identified with “ Asaphus”’ homalonotoides. Both cephalon and pygidium are similar to those of that species, but the anterior end of the cephalon is hardly elongate enough to justify a reference to Ectenaspis. It also seems better to restrict Isoteloides to forms like the type, J. whitfieldi, which has a rather distinctly outlined glabella and a narrow axial lobe. This species forms a connecting link between Isotelus and Ecte- naspis. ‘The anterior end of the cranidium, while not elongate, is pointed, and though the glabella is not definitely outlined, some traces of its shape can be seen, and a pair of faint glabellar furrows are present on some specimens. Horizon anp Locauiry:— A single cranidium of this species was found by Mr. Narraway in the Leray-Black River at Ottawa, Ont., and it is fairly common in the Glens Falls-Trenton at Pattersonville and Smith Basin, N. Y. The holotype is in the Carnegie Museum. ISOTELUS REJUVENIS, sp. nov. Entire specimen elongate oval, narrow, strongly convex. Cephalon large, with short genal spines which in uncrushed specimens have their outer surfaces nearly vertical. The facial sutures follow the same course as in J. towensis, being very close to, and parallel to the anterior margin. The eyes are very small, elevated, situated a trifle more than their own length in front of the pos- terior margin. The glabella is faintly outlined, constricted between the eyes, and nearly smooth. Thorax as in J. iowensis, the dorsal furrows shallow, and the axial lobe more than one third and less than one half the total width. Pygidium elongate, narrow, with steep sides. The axial lobe is narrow, faintly outlined except in young specimens, and without rings except for the one on the anterior end. The pleural lobes show traces of several pairs of ribs, two of which at the anterior end are very distinct. MrASUREMENTS:— The holotype is 105 mm. long; the cephalon is 38 mm. long and 62 mm. wide; the pygidium is 46 mm. long and 55 mm. wide. This species differs from Jsotelus iowensis in having smaller eyes, a longer and narrower pygidium with two pairs of ribs at the anterior end, and in having a less densely punctate shell. Horizon anp Loca.iry:— The species has so far been found only in the lower part of the Maquoketa at Clermont and Elgin, Iowa, at both of which places it is rather common in association with I. iowensis. The holotype, M. C. Z. 1,586, was collected by the writer on a creek about four miles west of Clermont. RAYMOND: SOME NEW ORDOVICIAN TRILOBITES. 295 ENCRINURIDAE Angelin. {ctenonotus, gen. nov. Among the anomalous trilobites described by Billings was one which had a glabella very like that of a Pliomerops, and a pygidium strongly suggestive of Encrinurus. Although no entire specimens have been reported the “glabella and pygidium were found in about equal numbers together, and in great abundance. Out of one small piece of rock searcely a yard in length, there were taken twenty-seven speci- mens of the glabella, and twenty-four of the pygidium. In this mass of rock there was no other head to which the pygidium could be referred, nor any other pygidium to which the head could possibly have belonged.” The pygidium is distinctly Encrinurus-like in its elongate narrow form, very long axial lobe with numerous rings, and _ particularly in the way in which the posterior ribs on the pleural lobes curve back around the end of the axial lobe. The pygidium shows some differ- ences from both Encrinurus and Cybele, but they are of a relatively minor character, and if it were not for the associated cranidium, the species would undoubtedly be admitted to the genus Encrinurus. While the cephalon is Pliomerops-like, certain Encrinurid char- acteristics may be seen in it, particularly when compared with Cybele. The form of the glabella and position of the glabellar furrows is similar to what is seen in Cybele bellatula (Dalman) (Schmidt, Mem. Acad. imp. sci. St. Petersburg, 1881, ser. 7, 30, p. 203, pl. 13, fig. 9) and the glabella does not expand toward the front as in Pliomerops. The most important point, however, is that the eye is not situated close to the glabella as in Pliomerops. The eye is not shown in any of the specimens but enough of the fixed cheek is preserved to indicate that, whether the eye is ultimately found to be far forward, as in Encrinu- rus and some species of Cybele, or far back as in other species of that genus, it must at least be placed at some distance from the glabella and thus be Encrinurid in position. Billings made the cranidium the holotype of the species Amphion westoni, so that in case it should prove that the cranidium and pygi- dium do not belong together, the pygidium will belong to an unnamed species. I propose to designate the specimen from Newfoundland retaining the thorax and pygidium as the holotype of the genus, in order that there may be in the future no uncertainty as to how the names should apply. 296 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY.

MYRMELEONIDAE. CYMOTHALES HERMOSA, sp. noy. Type.— M. C, Z. 10,565. N. Angola: Dalla Tando, 29 November (Le Moult); two specimens. Wings marked in general as in C. speciosa and eccentros; only very small stigmal spot as in eccentros; apical band broken up more by spots than in eccentros. ‘The upper part of the middle band is broader in front than behind (in eccentros broader behind). Head pale, black between and above antennae, antennae pale, dark on extreme base, vertex with a hump each side which has a slightly bilobed summit. Pronotum black, a pale line each side, and behind are two oblique lines on each side; thorax blackish, with a pale line each side; pleura dark. Abdomen pale with two black stripes above; legs pale, femur of front legs black except at base and tip, with dense black hair, and longer erect black bristles, hind femora also with black bristles. Front tarsus has basal joint longer than the fifth, the spurs a trifle longer than first and second joints together. In fore wing four to six cross-veins before any are crossed, but the radial sector arises farther out at the middle band; nine or more branches to radial sector; in hind wing one cross-vein before radial sector. Length fore wing 30 to 34 mm., hind wing, 35 to 88 mm. This belongs to the section or subgenus Mironius. CHAETOLEON, gen. nov. Differs from Brachynemurus, Austroleon, and allied genera in having erect enlarged bristles upon the mesonotum in front, also in that on the fore wing the second and third anal veins are united for a short distance, the second anal, however, does not approximate the first anal vein in its basal part (as in the Formicaleonini). The antennae are long and slender, with much enlarged tip. Legs slender, with very long bristles, the tarsus shorter than the tibia, the first tarsal joint a little longer than the second, spurs equal, two tarsal joints. Wings moderately slender, in fore wings three cross-veins before radial sector, in hind wings two such cross-veins; radial sector in fore wings arises much before the fork of the cubitus. Type.— Myrmeleon pumilis Burmeister. Brachynemurus pusillus Currie also belongs here. PUREN. I include in this genus Myrmeleon inscriptus Hagen. It differs from Psammoleon in having the basal joint of the tarsus much longer than — BANKS: NEW NEUROPTEROID INSECTS. 329 the second joint, and the spurs elongated and curved only near tip. In P. inscriptus, as in the genotype, the costal area of the fore wing is biareolate; in P. connexus this area has but one series of cells. Both differ from the type of Puren in having more (6 or 7) cross-veins before the radial sector in the fore wing. PUREN CONNEXUS, sp. nov. Type.— M. C. Z. 10,848. Calif.: San Jacinto Mts., 25 June (F. Grinnell). Head pale, a black interantennal mark, two transverse rows of black spots across vertex; pronotum black, a narrow median pale line, and on each side a spot in front and a line behind; mesonotum with pale spot and stripe each side. Abdomen black. Legs mostly black, hind tibia pale on outer basal half; femora and tibia with black bristles, some black and many white hairs; basal joint of tarsus twice as long as the second, spurs equal almost two joints, but little curved except near tip, the claws hardly one half as long as the spurs. Wings hyaline; veins pale, marked with black, mostly in long streaks. As in P. inscriptus there is in the fore wing a prominent flexuous dark line, formed by connecting the oblique mark at end of anal with that up from end of cubitus, this line is not as deeply incurved as in P. inscriptus. In both fore wings there is a strong vein from forking of cubitus obliquely upward and backward to the median, possibly this is abnormal. The wings are narrower than in P. in- scriptus, and the costal area has but a single series of cells. Expanse 54 mm. EREMOLEON NIGRIBASIS, Sp. NOv. TypE.— M. C. Z. 10,847.

In color markings and general appearance close to C. perpusillus. It differs from that species in lacking a row of black spines on the front side of the front femora, and in that the first joint of the front tarsus in the male is much shorter than the second joint, in fact less than half as long, and most important in the shape of the male genital parts (Plate 7, fig. 104), which seen from the side show no median projecting part which is characteristic of C. perpusillus. Of the same size as that species. ZAPOROTA, gen. nov. Related to Colpotaulius, but the spurs 0, 2, 2, and the pronotum short.

NOTES ON SOME AMERICAN BIRDS, CHIEFLY NEOTROPICAL By Ovurram Banos AND THomAsS E. PENARD. CAMBRIDGE, MASS., U.S. A.: PRINTED FOR THE MUSEUM. JANUARY, 1921. No. 4.— Notes on some American Birds, chiefly Neotropical. By Ourram Banas AND THomas E. PENARD. In the present paper we deal chiefly with some neotropical birds, erecting two new genera, describing one new species and five new subspecies, and reviewing the forms of a number of species, involving some changes and corrections in the nomenclature and synonymy of several forms. , All measurements are in millimeters; the tail is measured from the base of the free tail feathers to the extreme tip. We are indebted, for the loan of specimens, to Dr. Frank M. Chap- man of the American Museum of Natural History, Mr. Charles B. Cory of the Field Museum, Dr. Charles W. Richmond of the National Museum, and Mr. W. E. Clyde Todd of the Carnegie Museum. A NEW SUBSPECIES OF CROTOPHAGA SULCIROSTRIS SWAINSON. CROTOPHAGA SULCIROSTRIS PALLIDULA, subsp. nov. Type.— M. C.

Remarks.— Eighteen adults of this new form, laid out beside a series of nearly double that number from various points in Mexico and Central America, are strikingly different; the pale, dull colors of the Lower Californian bird cannot be matched by any specimen in our series of true sulcirostris. The difference is noticeable at a glance but rather difficult to describe. Brewster (Bull. M. C. Z., 1902, 40, p. 100), in his account of the birds of the Cape Region of Lower Cali- fornia, states that the Groove-billed Ami is not known to occur in central and northern Lower California, and that the colonies which have become established in the Cape region were probably originated by birds which came from western Mexico. However this may be, the isolated colony of Cape St. Lucas has developed into a very dis- tinct form, worthy of recognition. THE FORMS OF DENDROPLEX PICUS (GMELIN). Having discovered in the Lafresnaye collection the type of Dendro- colaptes altirostris Léotaud, we have examined all the specimens of Dendroplex picus in the M. C. Z., and have come to the conclusion that there are five forms, Léotaud’s bird being the Trinidad repre- sentative of the species. The material examined includes specimens from Santa Marta (Colombia), Margarita Island, Trinidad, Guiana, Upper Amazon, and eastern and southeastern Brazil. In general, immature birds of all forms have smaller, more blackish bills than do adults, and old skins which have been preserved in cabinets for a long time are sometimes more rufous in appearance than fresh specimens. ‘These facts should be borne in mind in making comparisons. Following is a brief summary of the six forms recognized :— 1. DENDROPLEX. PICUS PICUS (Gmelin). Oriolus picus Gmelin, Syst. nat., 1788, 1, p. 384 (‘‘ Habitat in Gujanae ar- boribus”’— based on Daubenton’s, PI. enl., 605 Cayenne). BANGS AND PENARD: NOTES ON AMERICAN BIRDS. 367 SUBSPECIFIC CHARACTERS.— Under parts dark, more olive — not far from Saccardo’s umber of Ridgway; upper back similar to under parts, but slightly more rufous; lower back, wings, and tail rufous-chestnut; the pale spots of the under parts small and less distinet on the belly. MeaAsuREMENTS.— Adult (twelve specimens) — wing, 93.0-99.5 (96.7); tail, 70.0-79.5 (74.9); tarsus, 19.5-21.5 (20.7); culmen from base of forehead, 27.0-30.5 (29.0). RanGE.— Guiana, eastern Venezuela (Orinoco Valley), northern Brazil (Rio Negro, Rio Branco). SPECIMENS EXAMINED.— Dutch Guiana: Vicinity of Paramaribo, 13; “Surinam” (Cragin), 1. British Guiana: Aunai (Whitely), 1. Total, 15. RemMaArkKs.— Unfortunately we have not seen specimens from the type-locality, Cayenne, but we assume that Surinam birds are suffi- ciently close for purposes of comparison. Menegaux and Hellmayr (Mém. Soe. hist. nat. Autun, 1906, 19, p. 109) give measurements of a male and female from Cayenne which are slightly larger than the birds from Surinam listed by them and those examined by us. The differ- ence, however, is very slight and probably would not prove to be constant in larger series. A male (Penard collection) from Aunai, British Guiana, collected by Henry Whitely, 14 March, 1890 (or 1891), is very rufous, and re- sembles specimens from Bahia, but in this case we think the rufous tone is due to fading and not to individual or seasonal variation. Specimens taken near Paramaribo in March do not differ in shade from others taken in January, February, April, May, June, or Decem- ber, all having the dark olive tone. On the other hand, a very old specimen (M. C. Z. 84,580) collected by Cragin in Surinam, has not faded appreciably and agrees very well with more recently collected specimens from the same locality. 2. DENDROPLEX PICUS ALTIROSTRIS (Léotaud). Dendrocolaptes altirostris Léotaud, Ois. Trin., 1866, p. 166 (Trinidad). Type.— M. C. Z. 77,156, Lafr. coll. 2,279. Adult 9.

Remarks.— In his work on the birds of Trinidad, Léotaud (loc. cit.) described a new Woodhewer under the name Dendrocolaptes altirostris, stating that the validity of the species had been confirmed by Lafres- naye to whom the type had been sent. Lafresnaye was to have re- turned it to Léotaud, but owing to the Baron’s death this had never been done. Léotaud (loc. cit., p. 167) says: “T’altirostris comme le picus se tient parmi les mangliers. Il parait étre trés rare ici, Car je n’ai jamais pu obtenir qu’un seul exem- plaire. Je l’ai envoyé & M. de Lafresnaye qui daignait alors m’ac- corder pour mon travail son concours aussi bienvieillant qu’éclairé. Il devait, 4 mon priére, me renvoyer Vexemplaire quand la mort l’a surpris: mon altirostris fait done partie jusqu’aujourd’hui de la col- lection qu’a laissée le Baron.” Chapman did not meet with the species while in Trinidad, but on the strength of Lafresnaye’s opinion, as cited by Léotaud, included it under the name Dendrocolaptes altirostris in his list of the birds of Trinidad (Cf. Bull. Amer. mus. nat. hist., 1894, 6, p. 48). On the other hand Hellmayr (Nov. zool., 1906, 18, p. 59) disposes of the name in the hypothetical list at the end of his paper on the birds of Trinidad, giving his reasons for so doing. The type, which is easily identified from Léotaud’s description, has two labels — one in a handwriting we take to be Léotaud’s, bearing simply the words “ Xiphorynchus altirostris, femelle,” and the other made out by Lafresnaye reading, “il ne différe du picus que par sa mand. plus arquée et par ses plumes écailleuses ventrales plus grandes et plus prolonguées vers l’anus.”’ The second specimen, M. C. Z. 77,155, Lafr. coll. 2,280, apparently had also been sent to Lafresnaye by Léotaud. It also has two labels — the first on paper exactly like that of the type, and in the same hand- writing, bearing the words, “ Dendroplex nigrirostris? organes sexuels atrophiés, ”’ and the second made out by Lafresnaye, reading, “ Dendro- plex picus Q ? rostro et ales brevioribus Trinidad.” This specimen is obviously an immature bird, with blackish bill, the culmen less curved than in the type of altirostris, but much heavier than in true picus of Guiana. The spotting of the under parts is less pronounced than i in the adult, but decidedly more so than in true picus. BANGS AND PENARD: NOTES ON AMERICAN BIRDS. 369 A third specimen, M. C. Z. 84,578, Lafr. coll. 8,490, the original label of which is missing, apparently also belongs to this race. It has the characteristic heavy bill, is even larger than the type of altirostris, and the under parts are spotted well down the lower belly. It can- not be an example of D. p. kienerti, which is also large, because it entirely lacks the deep cinnamon-rufous tone of that form. 3. DENDROPLEX PICUS KIENERIT (Deg Murs). Dendrornis kienerii Des Murs in Castelnau, Voy. Ois., 1856, p. 45, pl. 14, fig. 1 (ga, Rio Solimoéns). Type.— Paris Museum, fide Menegaux and Hellmayr. SUBSPECIFIC CHARACTERS.— Similar to Dendroplex picus picus Gmelin, but larger, and more cinnamon-rufous above and below. MEASUREMENTS.— Im.— wing, 106.0; tail, 81.0; tarsus, 22.0; culmen from base of forehead, 27.5. RaANGE.— Central and western Brazil, eastern Bolivia, eastern Peru. SPECIMEN EXAMINED.— Upper Amazon: one immature bird, Lafr. coll. 2,281, “haut amaz.” Remarks.— Although our specimen is an immature bird with blackish bill, its large size and darker, richer color, distinguish it at once from true picus. 4. DENDROPLEX PICUS BAHIAE, subsp. nov. Typr.— M. C. Z. 73,792. Bahia (trade skin). SUBSPECIFIC CHARACTERS.— Similar to Dendroplex picus picus Gmelin, but paler and more rufous, less olivaceous throughout; spotting on head larger and more conspicuous, and whiter, less buffy. MEASUREMENTS.— Tyre. Adult —wing, 100.00; tail, 79.5; tarsus, 20.0; culmen from base of forehead, 32.0. Adult (six specimens)— wing, 100.0-104.0 (101.5); tail, 79.5-85.0 (81.6); tarsus, 18.5-21.0 (20.0); culmen from base of forehead, 28.0- 32.0 (30.1). RanceE.— Eastern Brazil. SPECIMENS EXAMINED.— Eastern Brazil: Bahia (trade skins), 3; Ceara (trade skin), 1; Boa Vista (Schwanda), 3; Rio de Janeiro, 1. Total, 8. 370 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. Remarks.— Very likely the rufous appearance of the old Bahia skins is in part due to the age of the specimens, but we do not think it is wholly so. Three birds from Boa Vista (Penard coll.), collected by Schwanda in 1907, are of a deeper rufous shade, probably because they are much fresher. None has the olivaceous tone of the Guiana specimens. Perhaps birds from eastern Brazil average slightly larger than D. p. picus, as our measurements indicate, but our series is much too small to substantiate this. 5.

MEASUREMENTS.— CotypE.—Adult —wing, 104.0; tail, 80.0; tarsus, 22.0; culmen from base of forehead, 32.0.

SPECIMENS EXAMINED.— Colombia: Rio Hacha, 3 ad., including the type; near Santa Marta, 2 oo", 1 9; nolocality, 1. Total, 7. Remarks.— Cherrie (Mus. Brooklyn inst. Sci. bull., 1916, 2, p. 268) records specimens of both D. picus and D. picirostris taken at Ciudad Bolivar. He observes that on his previous expeditions he had not met with picus until he reached Perico. D. meus and D. picirostris are two very different looking birds, and intermediate forms are not known to exist. The occurrence of both at Ciudad Bolivar seems to indicate that they are distinct species, and they have been so considered for a long time. Chapman (Bull. Amer. mus. nat. hist., 1917, 36, p. 422), however, treats picirostris as a subspecies of picus. This view is in accordance with the principles announced by him in his remarks on the treatment of subspecies (Chapman, loc. cit., p. 175-179). He also met with picus in the BANGS AND PENARD: NOTES ON AMERICAN BIRDS. 371 Bogota region from where it had never been reported before and where he also found picirostris. Although we follow Chapman in treating D. picirostris as a race of D. picus, we strongly suspect that the two are specifically distinct. Stone (Proc. Acad. nat. sci. Phila., 1899, p. 51) lists a specimen as the type of D. picirostris, acquired by the Philadelphia Academy in the Delatre collection. The label of this specimen bears the locality N. Grenada, but does not specifically refer to the type-locality, Rio Hacha, mentioned in the original publication. In the Lafresnaye collection there are three specimens all marked as having come from Rio Hacha. One specimen in particular also refers to Delatre, its label reading as follows: “ Dendroplex picirostris nob. rev. 1847, p. 76, Ne Grenada (Rio hacha delatr.)”. This specimen, we think, has at least as good a claim to being the type as the one in the Philadelphia Academy’s collection. We therefore consider them both cotypes. 6.

SUBSPECIFIC CHARACTERS.— Similar to Dendroplex picus picirostris (Lafres- naye), and of about the same size, but bill longer and heavier, and tail shorter; feathers of throat whiter, without dark edges, and extending more over chest; the pale centers of feathers of lower breast broader. MEASUREMENTS.— Adult (two specimens) — wing, 100.0-102.0 (101); tail, 76.0-79.0 (77.5); tarsus, 22.0-23.0 (22.5); culmen from base of forehead, 33.0-35.5 (34.3). RanceE.— Island of Margarita. ' SPECIMENS EXAMINED.— Two adult males from the type-locality. Remarks.— If it should eventually be shown that D. picirostris is a distinct species, then D. longirostris ought to be considered a subspecies of it rather than of D. picus. THE IDENTITY OF TODIROSTRUM SPICIFERUM LAFRESNAYE. In the catalogue of the Lafresnaye collection, compiled by Verreaux, two specimens, 4,632 and 4,633, are listed as types of Todirostrum spiciferum Lafresnaye (Rev. zool., 1846, p. 363, “hab. in Brasilia’”— 372 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. Rio Negro, ex Berlepsch). Both specimens are now in the M. C, Z. The first of these we identify as the bird generally known as Lopho- triccus spiciferus (Lafresnaye), and the second the bird named Mota- cilla galeatus Boddaert (Tabl. Pl. enl., 1783, p. 24 — Cayenne, ex Daubenton’s PI. enl. 391, fig. 1). The original labels, however, reveal the fact that the second speci- men only is the type of Lafresnaye’s Todirostrum spiciferum. The label of this specimen, in Lafresnaye’s handwriting, reads, “Tod. spicifer, 'T. porte épi nob.,” and refers to the original publication. The description agrees perfectly with the specimen, which proves to be Colopteryx galeatus (Bodd.). Hellmayr (Abh. K. Bayer. akad. wiss., 1912, 26, abh. 2, p. 22, footnote) was the first to notice the dis- crepancy between the diagnosis of 7. spiciferum and the Upper Amazonian bird to which the name Lophotriccus spiciferus has been applied by authors, and with his customary keenness suspected its identity. Compared with fresh specimens from Surinam (Penard collection), Lafresnaye’s type is very similar, except that the bill is now of a horn color, and the coloration, in general, has a rather faded and slightly more brownish appearance, which, of course, is readily accounted for by the age of the specimen. Thus the name Todirostrum spiciferum Lafresnaye sinks into the synonymy of Colopteryx galeatus (Boddaert). By this unfortunate disposition of 7. spiciferwm, the genera Colop- teryx and Lophotriccus are both seriously affected. Lophotriccus was proposed, without designation of type, by Berlepsch (Proc. Zool. soc. London, 1883 [= 1884] p. 553), who listed as representative species L. spicifer (Lafr.) and L. squamicristatus (Lafr.). The geno- type was subsequently designated by Sclater (Cat. birds Brit. mus., 1888, 14, p. 86), who selected Lophotriccus spcifer Lafresnaye. Lopho- triccus is thus a synonym of Colopterus Cabanis. The latter being preoccupied, Ridgway (Proc. U. S. N. M., 1888, 10, p. 519) has sub- stituted Colopteryx, by which name the genus has been known ever since. But Colopteryx is antedated by Lophotriccus and must be replaced by it. The only species in the genus should thus be called Lophotriceus galeatus (Boddaert). The genus erroneously known as Lophotriccus is now without a name, since Orchilus Cabanis, which would otherwise be applicable here, is preoccupied by Orchilus Morris (Cf. Oberholser, Proc. Biol. soc. Wash., 1918, 31, p. 203), and since Orcheilus Gray is merely an emendation. We therefore propose for this genus Pea ow ets ¢ ap ee rn a. a eS ee ee a B -— BANGS AND PENARD: NOTES ON AMERICAN BIRDS. 373 COMETORNIS, gen. nov.

The specimen, Lafr. coll. 4,632, listed by Verreaux as one of the types of 7. spiciferum, has a label, in Verreaux’s handwriting, and is marked as having come from Peru instead of Brazil. This specimen does not agree with the description, and there is nothing to support Verreaux’s statement that it is a type. It is, however, the bird to which the name spiciferum has been erroneously applied by authors. We propose to call it COMETORNIS VITIOSUS, sp. Nov. Typr.— M. C.

SpEecIFIC CHARACTERS.— Differs from other species in this genus in having the elongated crest-feathers edged with whitish instead of cinnamon or cinna- mon-rufous. DESCRIPTION OF TYPE.— Top of head blackish, the elongated crest-feathers edged with whitish; upper parts olive-green, wings and tail dusky, margined with olive; wing-coverts and outer secondaries broadly tipped and edged with yellowish green; under parts grayish, slightly striped, breast with dusky markings; lower belly, sides and under tail-coverts pale greenish yellow. MEASUREMENTS.— Type. Adult — wing, 51.0; tail, 37.5; tarsus, 15.0; exposed culmen, 11.0. Remarks.— We would have preferred a freshly collected specimen for the type, rather than the old Lafresnaye specimen, but we have no other. Fortunately it is in a good state of preservation.

Later writers, including Hellmayr, have not followed this view, but have recognized rufipennis. Recently Hartert and Goodson (Nov. zool., 1917, 24, p. 412) have separated the West Ecuadorian form concerning which Hellmayr had expressed a doubt, naming it M. c. hellmayri, type-locality Cachabé, N. W. Ecuador. They also called attention to the slightly smaller size and grayer coloration of birds from Panama, but owing to lack of material did not come to a decision in regard to these. MusciFur, gen. nov. Tyre.— Myiarchus semirufus Sclater and Salvin, Proc. Zool. soe. London, 1878, p. 188, pl. 11. GENERIC CHARACTERS. — Superficially resembling Myiarchus Cabanis. Bill flat as in the subgenus Onychopterus Reichenbach, not deep as in true © Myiarchus; lateral edges decidedly convex, not straight. Wing rounded, not pointed; third (from outside), fourth, and fifth primaries longest; second about equal to sixth; first decidedly short, shorter than ninth; distance from longest primary to distal secondaries not more than length of middle toe without claw. Tail rounded, about equal to length of wing. Upper parts brownish olive, like the head; wings and tail rufous or with rufous edgings; lower parts uniform rufous, entirely lacking the characteristic gray breast and yellow belly of Myiarchus.

Intern. orn. congress, 1907, p. 478) also has called attention to the fact that M. semirufus did not belong in Myiarchus. THE FORMS OF TYRANNUS MELANCHOLICUS VIEILLOT. This wide-ranging species inhabits a vast area from the Lower Rio Grande in Texas, south to Argentina, and throughout its range is locally common. According to Chapman (Bull. Amer. mus. nat. hist., 1917, 36, p. 478) it is in the main a bird of the tropical zone, but ap- parently follows the trails and clearings up into the mountains, being found even on the Bogoté Savanna at an altitude of 8,750 feet. The species varies very little, especially within its South American range. One of the distinguishing characters usually ascribed to birds from northern South America, is the paler color of the back, but we find this very unreliable. In freshly moulted birds from all parts of the range of the species, the upper parts are olive greenish, while in birds in worn, post-breeding plumage, the back is often faded to a dull gray color with practically no olive tone. On the whole, however, birds from southern South America, true 7. m. melancholicus, are a trifle darker than those from northern South America. We have been confronted by the usual unreliability in regard to sex determinations in species the males and females of which are similarly colored; for if, as is generally supposed, the male of this species is larger than the female, many of the specimens have been wrongly sexed by collectors. After examining much material, we have decided to ignore the sex marks on the labels altogether, although disposed to regard the smaller specimens of each form as females. In comparing a very large number of specimens from various parts of Central and South America, we distinguish five forms, of which the characters and geographical distribution are as follows: — 1.

Remarks.— There has been much uncertainty in regard to the range of true melancholicus. We refer to this form all birds from Argentina and Uruguay northward to western Colombia and to South Brazil. Birds from western Colombia and western Ecuador are, as a matter of fact, intermediate in coloration, between true melancholicus and the form inhabiting northern South America. Like true melan- cholicus they possess the wide chest-band, which, however, is slightly more yellowish in tone, not so grayish. On the whole, they are very close to true melancholicus and hardly distinguishable in parallel series. The difference is certainly too small to warrant further subdivision. 2. ‘TYRANNUS MELANCHOLICUS DESPOTES (Lichtenstein). Muscicapa despotes Lichtenstein, Verz. doubl., 1823, p. 55 (Bahia, Brazil).

Remarks.— This small form is intermediate in coloration between T. m. melancholicus of Paraguay and 7’. m. chloronotus of Yucatan. Within its range from Bahia to Merida, Venezuela, we are able to detect some geographical variation, but this is so slight that it would serve no good purpose to recognize more than one form. Birds from Bahia, of which we have unfortunately seen only three specimens, are not quite so distinctive as birds from northern South America, but they are certainly much closer to the latter than to true melancholicus. Our examples from Bahia are small like those from Guiana, but the chest-band, although distinctly more yellowish than grayish, is some- what wider. Since there is already a name available for the Bahia bird, we prefer to adopt it for the entire series rather than to pro- pose a new one for the more distinctive northern birds. We refer birds from Trinidad, Tobago, Margarita Island, and Union Island, to this form, although they seem to be intermediate between birds from Guiana and Central America. In our examples from the islands mentioned the chest-band is like that of the Guiana birds, but the throat is a trifle more whitish. We cannot, however, justify a further subdivision based upon such a very slight difference, even should it eventually prove to be constant. In describing Laphyctes satrapa, Cabanis and Heine (Mus. Hein., 1859, 2, p. 77), drew the characters entirely from the Mexican bird to which Lichtenstein had given the manuscript name satrapa (Berlin Museum coll.). The only constant character mentioned in the diagnosis, is the larger size, which fixes the name upon the form in- habiting northern Mexico, known as Tyrannus melancholicus couchii Baird, and not upon the form inhabiting northern South America, which is even smaller than true melancholicus. As Ridgway (Bull. 50, U. S. N. M. 1907, pt. 4, p. 703) remarks, Cabanis and Heine even doubtfully referred the South American specimens, from Guiana and Venezuela, to this form. The type of Laphyctes satrapa is thus among the specimens in the Berlin Museum, presumably the same recorded by Lichtenstein as Tyrannus satrapa in his Nomenclator Avium Musei zoologici Berolinensis, 1854, p. 16, type-locality Mexico. In accord- ance with this view 7. m. satrapa (Cabanis and Heine) becomes a synonym of 7’. m. couchit Baird. We may add that previous to Ridg- way, Berlepsch (Proc. Intern. orn. congress, 1907, p. 474) had already called attention to the probable identity of the two names. The names Muscicapa furcata Spix and Tyrannus crudelis Swainson, 3380 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. cited in the synonymy above, may apply to this form or perhaps to 7. m. melancholicus, but as neither Spix nor Swainson gave sufficient information in regard to the type-localities in Brazil, it would be necessary to examine and compare the types in order to determine to which of the two forms these names properly belong. In the plate representing M. furcata the chest-band is very wide and dark, more like that of true melancholicus, but Hellmayr (Abh. K. Bayer. akad. wiss., 1906, 22, abt. 3, p. 666) says the type does not differ from a much worn specimen from Paraguay, and that the chest and back are shown much too green in the plate. 3. ‘TYRANNUS MELANCHOLICUS CHLORONOTUS Berlepsch.

Remarks.— This is the largest of the forms of 7. melancholicus. 382 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. The largest examples occur in the northern parts of its range, in Texas and Northeast Mexico, and from there southward the form gradually merges into 7’. m. chloronotus. In freshly moulted birds the back is a little paler olive-green than in true 7’. m. melancholicus, but we cannot detect any differences in the color of wings and tail of the two forms. THE FORMS OF PACHYRHAMPHUS POLYCHOPTERUS (VIEILLOT) AND PACHYRHAMPHUS MARGINATUS (LICHTENSTEIN), Having examined nearly all specimens of Pachyrhamphus poly- chopterus and Pachyrhamphus marginatus available in this country, we are able to throw some light on the geographical forms of these two closely related species. Males of the paler forms of P. polychopterus superficially resemble males of P. marginatus, but they are really quite distinct and readily identifiable. The male of the P. marginatus group differs from that of the P. polychopterus group in having a broad white frontal band, although some specimens of the polychopterus group, especially in the paler forms, possess distinct white lores. The females of the two species are distinguishable at a glance. In the P. polychopterus group the head of the female is of about the same color as the back, or a little darker, while in the P. marginatus group — the head is always reddish brown, contrasting sharply with the olive- green of the back. I. THE PACHYRHAMPHUS POLYCHOPTERUS GROUP. a There appears to be considerable confusion among ornithologists in regard to the forms of Pachyrhamphus polychopterus, partly, no doubt, owing to lack of material for comparison. The series of specimens at our disposal, arranged in accordance with the geographical distribution of the species, not only shows very plainly the existence of more forms than have hitherto been recognized, but exhibits in a marked degree the great amount of individual varia- tion in the plumage of the males of the darker forms.

ApRIL, 1921. =e € : eae No. 6.— The Brachiopoda of the Maquoketa of Iowa. By Joun H. Braptey, Jr. INTRODUCTION, Tue publication of a large number of new and curious trilobites from the Maquoketa of Clermont and nearby localities in northeastern Iowa by Slocum has caused renewed attention to be given to a region which has for many years been known for its fossils. In 1917, in company with Prof. P. E. Raymond, I spent a week at Clermont, where, with the efficient guidance and assistance of Mr. A. H. Becker, a collection of representative fossils was secured. ‘The present paper is primarily a description of the brachiopods, and though there are fewer novelties among the brachiopods than were found among the trilobites from the same locality, it is nevertheless true that, including the eight new species, nineteen out of twenty-seven species are known only from the Maquoketa. Lingula beltrami, Plectorthis (Austinella) kankakensis, P. (A.) whitfieldi, Dalmanella macrior, D. corpulenta, Dinorthis proavita, Leptaena unicostata, Strophomena acuta, S. wis- consinensis, S. planodorsata, and Parastrophia divergens are, with few exceptions, restricted to the highest Ordovician of Iowa, Minnesota, and Wisconsin, and none of them has been found in Ohio or Indiana. Five of the remaining eight species, Hebertella insculpta, Plaesiomys subquadrata, Strophomena neglecta, S. nutans, and Rhynchotrema capax are characteristic fossils of the typical Richmond, while three, Crania laelia, Hebertella sinuata, and Plectambonites rugosus, are found in both the Cincinnatian and Richmond. The Trentonian aspect of the fauna is expressed in some of the Strophomenae, in the small Plectambonites and Zygospira, and in the presence of Parastrophia. The dominant facies is, however, Rich- mondian, though none of the typical fossils of the late Richmond is present. MAQuOKETA SHALE. Position and Distribution: —Few formations have been more written about or more misunderstood than the Maquoketa shale. Hall, the first to recognize it, called it the “ Hudson River formation,” a term which is now bereft of meaning. It was first formally labeled “Maquoketa shale” in 1870 by White, who supposed it to represent O04 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY, some particular epochal subdivision of the Cincinnati group. This non-committal usage of the term has continued to the present time, so that now as formerly, the Maquoketa comprises those late Ordovi- cian sediments that occur.in lowa, Wisconsin, Minnesota, and Illinois, underlain by the massive Galena and overlain by the equally massive dolomite of the Niagara. The exposures of this formation extend over a long narrow area in the states mentioned, usually bordering the Mississippi River. It follows the same northwest, southeast strike as the Galena and Niagara. ‘The most southerly exposure is in Jackson County, Iowa. South from there, it disappears and the Galena and Niagara meet. To the north the Maquoketa thickens and attains a maximum of 200 ft. (Calvin). In northeastern Lowa it again decreases and slowly thins out in southern Minnesota, where in some places it is discernible with a thickness of but a few inches. The great difficulty encountered in attempting to correlate the Maquoketa shale is due to the fact that the formation has not been correlated either lithologically or palaeontologically within itself. Equivalent strata of different but not very widely separated localities often show entirely dissimilar lithologic and faunal characters. For example, the heavy dolomitic beds at Clermont have no vestige of similarity to the strata of the typical region at Graf, lowa. The Ctenodonta and Orthoceras beds of Dubuque County are not present in Fayette or Winneshiek Counties. In the light of this fact it can be appreciated why investigators have had difficulty in correlating these beds with any part of supposed equivalents in Ohio or New York. Origin: — The heterogeneity of the Maquoketa shale has led writers to infer a shallow water or shore origin. The great localization of faunas and the local lithologic variation is the basis of this decision. In many places the muddy facies of shore deposition is_evident. Shrinkage cracks on some of the layers, the broken condition of most of the fossils and a certain irregularity in bedding in Winneshiek County, Iowa, led members of the state Survey to call this an old beach de- posit (1905). The Maquoketa appears to have been laid down in comparatively shallow water, just how deep it is impossible to say. The land-locked Galena sea with its arid shores and salty waters gave way to a body of water freely communicating with the open ocean. Mechanical sediments, indicative of general rainfall, were laid down in water of normal density. The lithologic and faunal differences were no greater than those to be seen in the sediments and life of shallow seas today. BRADLEY: BRACHIOPODA OF THE MAQUOKETA OF IOWA. 505 A marked lithologic change is observed in all places at the boundary between the Galena and Maquoketa. Whether the Maquoketa was preceded by a period of erosion is still uncertain. In Dubuque County, Iowa, no erosion of the Galena can be noticed and no unconformity. At Graf, on the other hand, the Galena dolomite and the blue shale of the Maquoketa have a bed of yellow clay between them, a sugges- tion of erosional unconformity. Lithologic Character:— Although much variation in composition is typical of the Maquoketa, dark bluish gray clay-shale predominates. The formation may occur as a single undivided body of shale. In one locality it outcrops as dolomite and limestone to a thickness of forty feet. In northern Iowa the formation falls naturally into four members : — 4. Brainerd shale. Blue and bluish gray shale with strata of limestone inter- bedded at top and bottom. 120 feet. 3. Fort Atkinson limestone. Massive yellow cherty dolomite with associated beds of limestone. 40 feet. Clermont shale. Bluish, plastic, fine-grained shale, well developed at Cler- mont, lowa. 15 feet. 1. Elgin shaly limestone. Limestone, dolomite, shaly limestone with beds of calcareous shale and thin partings of bluish less calcareous clay that are variable in character and fossil content. This division, unfortunately, does not persist throughout the formation. A division into three members seems to be the more universally applicable although this is not a hard and fast rule. bo LINGULIDAE. LINGULA BELTRAMI Winchell and Schuchert.

It is hard to separate these species in some instances, because of the varia- tion in the number of striations which characterizes them both. Where they occur abundantly together, as at Clermont, they have a tendency to intergrade into each other. The pedicle-valve has a distinct beak; cardinal area arched; del- thyrium triangular. The striations are quite strong; their number varies from thirty-six to forty-eight. This is the chief distinction between whitfieldi and kankakensis, the latter possessing sixty to seventy striae on the anterior margin. The striations in both species increase by implantation. The brachial-valve is much less convex than the other; a slight flattening along the middle grades into a slight concavity at the 50S BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. anterior margin in large specimens.

Hebertella sinuata differs from H. occidentalis in the absence of the slight median depression near the beak of the pedicle-valve of the latter. This species is very common throughout the Richmond, and everywhere shows great similarity to H. occidentalis. The primary striations are coarser than those of the latter, but all intermediate stages can usually be found. Since all the specimens from the Upper Maquoketa at Brainerd, Iowa, were coarsely striated, no differentation of two forms was in- dicated.

The pedicle-valve has a medial ridge, gently convex at the anterior edge, but growing sharper toward the posterior margin where it merges into a pointed beak, that deviates but slightly from the vertical. The brachial-valve is about equally convex with the pedicle and possesses a shallow sinus which begins at the anterior margin and continues nearly to the beak, where it merges into the general convex- ity of the shell.

Two specimens of this common species were found at Clermont by the writer. This fossil is very characteristic of the Upper portion of the Maquoketa shale and is found plentifully at Spring Valley, Minne- sota. These rocks are known to be of about the same age as the Maquoketa of Iowa, so one must look for the cause of the scarcity of Dinorthis subquadrata in the shales at Clermont. This species is more convex than the Orthidae with which it is associated. It has a shallow sinus on the pedicle-valve, but not nearly so pronounced a one as that of its close relative, Dinorthis proavita. One feature separates it conclusively from the other species in this locality; the posterior lateral radiating striae curve so strongly outward that a few of them run out on the cardinal edge before reach- 512 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. ing the lateral margins. Striae increase by bifurcation on the pedicle- valve and by intercalation on the brachial. Winchell and Schuchert have pointed out how Déinorthis meedsi developed from D. pectinella var. sweeneyi by the multiplication of striae; how this development was carried further in D. meedsi var. germana, and how this form is closely linked with Plaesiomys sub- quadrata. Dinorthis proavita and Plaesiomys subquadrata show a reversion to ancestral characteristics in the simplicity of the striae and the rareness with which interpolation and bifurcation takes place beyond the early neanic stage.

Several specimens of this species were found at Clermont and resemble in all essentials the types from Spring Valley, Minnesota. The striae increase by interpolation on the brachial and by bifurcation on the pedicle-valve. The latter is somewhat elevated at the umbo, flattened and in some cases concave toward the lateral and anterior margins with a slight mesial elevation. The distinguishing charac- teristic of this form is the brachial-valve which is always convex and possesses a well-pronounced sinus. No other species of Orthidae present at Clermont has the very noticeable sinus of this species. Dinorthis proavita and D. iphigenia Billings are superficially similar, but they have the fold and sinus reversed. The latter has a greater number of striae and is found only in the Trenton of Canada.

The concentric banding and filming is often absent as well as the consequent thickening of the valves anteriorly. This is the case with most of the specimens from the Maquoketa near Clermont, Iowa; the surface is comparatively smooth except for concentric striae present on some forms. Plectambonites rugosus has a considerable vertical range; it is most abundant in the Eden, but similar forms have been found in the Waynesville and Liberty members of the Richmond. Much varia- tion of outline occurs within the species, and on the same slab examples may be seen representing all stages between the semielliptical and the elongate quadrangular. These shells grow more in width than > length, and environment often differentiates them so greatly as to 514 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. raise the question whether all the specimens under discussion should be considered one species.

The specimens lack any sign of the wrinkling present in some of the examples from Spring Valley, Minnesota. This species can be distinguished from the American form now called Leptaena tenuistriata Sowerby by the obsolete wrinkling, the large mid-rib and the large bilobed diductor scars of the pedicle-valve.

Length,9to10mm._ Pedicle-valve convex and strongly deflected near the anterior margin. The concave brachial-valve follows closely the convexity of the other. Cardinal area on the pedicle-shell narrow, never exceeding 2 mm. in width, with a small triangular deltidium. No interior known. The surface of some specimens is marked by fine radiating striae which grow heavier on the deflected area of the pedicle-valve. In most cases these striations are not noticeable and never attain the prominence of those on L. wnicostata, which is common in the Upper Maquoketa. A strong mesial line is present on the pedicle-valve and often bifureates before it reaches the anterior margin, in some specimens very near the hinge line. Locality: — Lower Maquoketa at Clermont, Iowa. Holotype, M. C. Z. 8,545. Several species of Rafinesquina and Strophomena occur plentifully in the Upper Maquoketa at localities north and west of Clermont, Iowa. R. kingi (Whitfield), S. cardinalis (Whitfield), and S. fluctuosa occidentalis Foerste, common in the Maquoketa of other Upper Mississippi Valley localities, were not found by the writer. A general characteristic of the new species of Rafinesquina and Strophomena described below is that they are considerably smaller than species from other localities in the Richmond. This dwarfing may have been the first manifestation of the force which drove both genera to extinction at the close of the Ordovician. Although dwarf faunas were common in Palaeozoic times, as they are now, it is not always easy to determine the cause. In the case of the one under discussion, there were probably many contributory causes. It appears that any change from the usual environmental conditions affect the sensitive soft parts of marine invertebrates. Professor Shimer says on this point, “ Whatever ill or good conditions the animal is subjected to are expressed in the shell, as moist and dry summers are recorded by the annual rings of exogenous trees.”’ With the universal uplift that came as the grand finale to the Ordovician period, many changes were wrought that had great in- fluence upon life in the sea. With the receding of the waters, lakes, and shallow bays were formed that lost their connection with the 516 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. main sea. The life entrapped in these basins must have been sub- jected to new environmental conditions. A change in the chemical constitution resulting from a freshening of the sea-water due to the new drainage; a concentration of salt; an abnormal increase in hydrogen sulphide and other gases; mud and other impurities; varia- tions in the temperature and the depth of water are agencies in dwarfing according to Professor Shimer. It seems that in the case of the Strophomenae and Rafinesquinae from Clermont, the ingress of mud was probably the determining factor. Upon examination of the fine-grained shales that contain these fossils, it is easy to imagine that conditions during the Maquo- keta deposition in this region were not unlike those that exist today in the Mediterranean Sea. De Lapparent noticed that while the fauna of the western Mediterranean was dwarfed, that of the eastern part was still further affected. He attributed this to the presence in the water of the eastern basin of fine particles of mud, which sank to the bottom only very slowly. Fine grains of mud taken into the tender soft parts of these brachiopods might easily have caused an irritation that would result in the prevention of normal growth. RAFINESQUINA ALTIDORSATA, Sp. NOV. Plate 2, fig. 2. Shell small and highly convex, almost hemispherical, with the greatest convexity in mature specimens a little nearer the beak than the anterior margin, although very nearly mid-way between. The more prominent radiating lines of the pedicle-valve occur at intervals of less than one millimeter and the intermediate spaces are occupied by four to six finer striae. The interior of the brachial-valve is thickened along the anterior margin. Three ridges running lengthwise to the hinge embrace the four adductor muscle-scars. Typical specimens measured: — Width Length Greatest convexity 22 mm. 19 mm. 11 .mm. 24.5 mm. 19 mm. 10 mm. 26 mm. 19.5 mm. 13.5 mm. The common Maquoketa representative of the genus at Delafield, Wisconsin and Spring Valley, Minnesota, is R. kingi (Whitfield), but its place was taken at Clermont by two new forms, R. subquadrata and BRADLEY: BRACHIOPODA OF THE MAQUOKETA OF IOWA. 517 R. altidorsata. They are much smaller than R. kingi and show the tendency to dwarfing that characterizes this fauna. [. subquadrata and R. altidorsata differ greatly from R. kingi and seem to be the first dwarf forms described from the Maquoketa. Locality: — Lower Maquoketa at Clermont, Iowa. Holotype, M. C, Z., 8,544. RAFINESQUINA SUBQUADRATA, sp. nov. Plate 2, fig. 1. Shell of medium size, with a tendency to squareness; width at hinge-line usually maintained and occasionally slightly exceeded as far as two thirds the distance to the anterior margin. Cardinal angles regularly square, but in some specimens slightly alate. Striations of the pedicle-valve alternate; usually three, sometimes two or four finer striae embraced by two coarser ones in the region directly anterior to the beak. All regularly grow heavier as the shell gtows older and increase by implantation, so that four or five finer striae are embraced by two coarser. The greatest convexity of the pedicle-valve is between one half and two thirds the distance from beak to anterior margin; at this point there is a ratherisharp inflection of the shell. The striations on the brachial correspond to those of the pedicle- valve, but are not so pronounced. The concavity of this shell follows closely the convexity of the other like two nested cups. The cardinal area is narrow, scarcely two millimeters wide at the most. Pedicle-opening very minute, just visible to the eye. Three typical specimens measured : — Width Length Greatest convexity 27 mm. 26.5 mm. 10 mm. 27 mm. 26.5 mm. 11 mm. 27 mm. 30 mm. 12 mm. Locality: — Lower Maquoketa at Clermont, Towa. Holotype, M. C.

Shell much broader than long, widest at the hinge, which projects into broad “ears”? which are demarked by shallow depressions. Pedicle-valve gently and rather evenly convex, highest in front of 518 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. the middle. The brachial shell, except in the umbonal region, follows the curvature of its opposite. ‘The striae of the umbonal region are of uniform size, but towards the front they show distinct alternations, and there are from one to three fine striations between each pair of coarse ones, the number varying with the distance from the margin.. When the shell is partially exfoliated, rows of conspicuous pores are disclosed in the furrows between the striae. Some specimens show distinct wrinkles on the sides near the hinge. Some are located nearly at right angles with the hinge, others diagonally, the variable position suggesting pathologic origin for these features. Measurements: — A specimen from the Lower Maquoketa near Clermont is 41 mm. long, and about 65 mm. wide; one figured by Winchell and Schuchert is 40 mm. long and 60 mm. wide. Rafinesquina alternata var. loxorhytis was a name suggested by Meek (Pal. Ohio, 1873, 1, p. 91) in a brief description which was not accom- panied by a figure. The variety does not appear to have been identi- fied successfully away from Cincinnati, and, as Cumings has remarked, (32d Ann. rept. Dept. geol. nat. res. Indiana, 1908, p. 928) the charac- teristic which appeared most important to the describer may not be a reliable one. Meek relied upon the extended form and obliquely wrinkled lateral extremities for the identification of this variety, but oblique wrinkles near the cardinal margin have proven in many cases to be the accompaniment of individual senescence or result of accident. The specimens from the Richmond of Indiana identified as R. alternata loxorhytis by Cumings lacked the wrinkles. Winchell and Schuchert found a large Rafinesquina at Spring Valley, Minnesota, which they illustrated under this name, but which has recently been referred to R. kingi Whitfield (Bassler, Bull. 92, pt. 2, U. S. N. M., 1915, p. 1087.) ‘If Whitfield’s description and illustrations are correct, then the Minnesotan form cannot be R. kingi, for its author stated that that species showed no alternations of striae, and the figure shows the Wisconsin shell to be much longer than that from Minnesota. Comparison with R. alternata loxorhytis cannot be satisfactory in our present ignorance of that variety, but Meek described it as having acutely angular, flattened, scarcely deflected cardinal angles, while the present species has convex “ears” which are set off by a conspicu- ous depression. It also has a much broader form than any of the shells which are usually designated as varieties of R. alternata. Locality: —In the Maquoketa near Spring Valley, Minnesota, and Clermont, Iowa; rare at the latter place. : % BRADLEY: BRACHIOPODA OF THE MAQUOKETA OF IOWA. 519 STROPHOMENA NEGLECTA (James).

Three good specimens from Clermont, Iowa, show a general simi- larity to the figured types from the Maquoketa at Spring Valley, 520 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. Minnesota. All are shorter than those in Professor Schuchert’s collection, and the anterior margins are less pointed. Very slight wrinkling is discernible on the valves near the hinge-line, and in one specimen is almost obsolete. The striae are more distinct on the brachial- than on the pedicle- valve; clearly alternating, usually three or four, rarely two or five, finer between two coarser ones. ‘The finer striae vary in intensity and in places are undulatory; the coarser in all cases are less erratic than the finer. Seven or eight of the prominent ones are counted in 5 mm. at the anterior margin. One specimen has dimensions as follows: — Width along hinge-line, — 28.5 mm.; across middle, 24 mm.; length of pedicle-valve, 20.5 mm.; of the brachial, 20 mm.; greatest convexity, 8 mm. at 13.5 mm. from the beak; height of cardinal area, 3.5 mm. This represents the medium of the three specimens. The largest had a width at the hinge of 37.8 mm. and length of pedicle-valve of 23mm. ‘The smallest had width at hinge 21.2 mm., and length of pedicle-valve 16.2 mm. A specimen from the type-locality measured by Foerste corresponded nearly to the first cited above, the main difference being a length of pedicle-valve greater by 1.2 mm. in the type.

Evidently similar to specimens from the type-locality at Delafield, Wisconsin are the two from Clermont, Iowa. They are characterized by the great convexity of the brachial-valve which has a sudden flattening toward the posterior part, and the regular generic depres- sion near the beak. The cardinal area of the pedicle-valve is almost parallel to the flattened surface. One specimen is distinctive not only for its peculiar specific idiosyn- crasies, but also for a pathologic condition shown in the arrestment of growth across the middle of the brachial-valve. Length, 17 mm., width, 24 mm., greatest convexity, 9.5 mm. The main difference between the specimens from Clermont and the types is that the cardinal area is not nearly so high in the former as in the latter. Locality: — Delafield, Wisc., and Clermont, Iowa.

At Patterson’s Spring near Brainerd, Iowa, the Niagara limestone is well exposed. Below it lies a zone of shale six feet thick. Both 522 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. are quite barren of fossils. Next in descent is a highly fossiliferous calcareous shale, from which slabs were dug that literally teemed with fossil shells. Several of these slabs were obtained, and although Rafinesquina is well represented on them, Strophomena is absent with the single exception of a pedicle-valve of Strophomena planodorsata. STROPHOMENA ABSCISSA, Sp. NOV. Plate 1, fig. 6. Shell small, roughly triangular in outline. Hinge-line straight; cardinal angles often mucronate, especially in the younger specimens. Greatest height of the cardinal area varies from one to two milli- meters. The surface of the brachial-valve is abruptly deflected from three to six millimeters posterior to the margin, the angle formed measuring 90°-105°. This sudden deflection is a highly characteristic feature of this form and makes confusion with any other Maquoketa species impossible. The pedicle-valve is weakly convex at the beak, then turns and follows the shape of the brachial-shell, producing a cup-like cavity, which lacks the sharp angles of the brachial-valves. Striae are distinctly alternating on the brachial-valve, from three to nine finer between two coarser ones. The coarser striae become more pronounced upon the vertical part of the brachial-valve; the finer intercalated ones tend to become obscure on this area, with the exception of one to three in each series which become coarse. This makes the deflected anterior region of the shell quite distinctly striated and sharply contrasts it with the finely marked posterior part. Specimens vary little in size, a typical one measuring 15 mm. along the hinge-line, 10 mm. in length, 5 mm. in depth. Locality: — Lower Maquoketa at Clermont, Iowa. Holotype, M. C. Z. 8,540.

In the adult the brachial-valve is marked by lamellose growth-lines that suggest premature senility. Striations on the brachial-valve are fine, from twelve to fifteen within’ 5 mm. on the anterior margin. They show an unpronounced alternation of two coarser encompassing one or two finer striae. On the pedicle-valve they are finer, from seventeen to twenty in 5 mm. They show the same alternation as those of the brachial-shell. A typical specimen measured: — Width Length Greatest convexity 17 mm. 15 mm, 6 mm. Locality: — Lower Maquoketa at Clermont, Iowa. Holotype, M. C. Z. 8,542. STROPHOMENA sp. ind. A small specimen 16 mm. wide along the hinge-line, 12.5 mm. long, and with a convexity of 3 mm., which equals the greatest height of the cardinal area, shows a pathological dwarfed condition. Striae are fine, five or six in 2 mm. and show no alternation. Concentric lines which tend to be prominent and lamellose are present. Concentric striae are prominent near the posterior edge of the pedicle-valve and form file-like indentations upon the radial striae. Retardation of growth is noticeable on the brachial-valve where the first concentric line is badly malformed. The pathological condition is so marked that it is difficult to identify the species and justifies a separate description. PORAMBONITIDAE. PARASTROPHIA DIVERGENS Hall and Clarke.

Half-way to the anterior margin the surface becomes abruptly depressed, forming broad, deep, characteristic sinus, which contains three well-defined plications. Two less-defined ribs occur on each lateral slope. 524 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. The brachial-valve is well rounded in the posterior region; the median fold becomes evident half-way to the anterior margin where it finally is well defined. The fold bears four plications; each lateral slope bears two. The type-specimens: from Wilmington have from three to five plications on the median fold and three on each lateral slope. All plications, and also the fold and sinus fade away in the umbonal region, which is smooth. Width Length Greatest convexity 15 mm. 12 mm. 10 mm.

This well-known species is quite plentiful in several exposures of the Lower Maquoketa at Clermont, Iowa. The shell is of medium size, and varies greatly in shape with age. Some mature specimens BRADLEY: BRACHIOPODA OF THE MAQUOKETA OF IOWA. = 525 were more convex than their diameter in any other direction. The posterior lateral margins meet the beak sharply in young shells, but become more rounded in the adult. The brachial-valve is always a little more convex than the pedicle and marked by a mesial ridge nearly flat and topped with four plica- tions. This continues about two thirds the way to the beak which is strongly incurved; lateral slopes bear from four to eight simple plications. The pedicle-valve terminates abruptly in a pointed beak which becomes strongly incurved upon that of the other shell in adults. The mesial sinus is deep and well defined in mature examples, bearing three or four sharp plications; lateral slopes each have five to seven simple striations. The entire surface of both valves is marked by numerous very regular, strongly zigzag, and prominent lines of growth. Rhynchotrema capax is larger than R. increbescens with which it is sometimes confused and has a greater convexity and thicker valves. This species varies much in the development from the young to the adult form and has caused the name of R. capax to cover a multitude of faulty identifications. Locality: — Richmond at Richmond, Indiana; Oxford, ete., Ohio; Illinois; JIowa; ‘Tennessee; Missouri; Wisconsin; Minnesota; Anticosti; Lake Winnipeg, Manitoba; Fort Churchill, Hudson Bay, etc, ZYGOSPIRA TANTILLA, Sp. Nov. Shell small, biconvex, the pedicle-valve sharply keeled in the umbonal region; the anterior edge sharp. The brachial-valve is convex at the umbo, becomes flattened in front, with a broad shallow median sinus. ‘The surface is covered with fine plications, the median one on the brachial-valve slightly thicker than the others. On either side of the median plane there are ten to twelve ribs. Measurements: — The largest specimen is 5.75 mm. long and 5.50 mm. wide. A small one is 4 mm. long and 3 mm. wide. This species is very like Z. recurvirostris, and differs from the other Richmondian forms in its small size. It is a less robust shell than Z. recurvirostris, and has fewer plications than Z. modesta. It is not unlike Z. kentuckiensis, but is smaller, less plump, and that species does not appear to show an enlarged median plication.

By WatutrAM Morton WHEELER. - ¢ on CONTRIBUTIONS FROM THE ENTOMOLOGICAL LABORATORY OF THE BUSSEY Institution, HArvArp University, No. 151. Wirntn the past months I have received several small collections of Chinese ants. Some of them were made in Soochow, Mokanshan, and other localities by Prof. N. Gist Gee, one was made in Hong-kong by Mr. Terry and contributed by Dr. F. X. Williams, of Honolulu, one in various localities in southern China by Mr. F. Muir, and one in Canton by Prof. C. W. Howard. Although several species of Formi- cidae have been recorded from China, their distribution is so imper- fectly known that it seems advisable to publish a list of my specimens, especially as everything pertaining to the fauna and flora of eastern Asia is of interest in connection with recent discussions of the problems of geographical distribution. Most of the ants received from Professor Gee, including several singular new species and some heretofore known only from Japan, belong, of course, to the Palaearctic fauna, whereas those from southern China are mostly identical with well- known species from India, Burma, and Siam and therefore belong to the Indomalayan fauna. - FormicipaE: PONERINAE. 1.

EcroMoOMYRMEX JAVANUS Mayr. One worker from Kuling, near Kiu-kiang. Nine workers from — Mokanshan, one from Soochow and one female from Loka, between Shanghai and Foochow (Gee). 5. Euponera (BRACHYPONERA) LUTEIPES (Mayr). A single worker from Hong-kong (Terry). Common throughout India, Ceylon, Burma, the Philippines, and the Malay Peninsula. 6. Evprponera (BRACHYPONERA) NIGRITA Emery subsp. CHINENSIS Emery. Workers and females from Soochow and several workers from Mokanshan (Gee). The female measures 5 mm. The node is broader, higher, and more compressed anteroposteriorly than in the worker. The wings are rather opaque, grayish hyaline, with pale brown veins and pterostigma. ! This subspecies was originally described from Shanghai. The typical nigrila ranges over Burma, Tenasserim, and India and is ~ closely related to E. (B.) solitaria F. Smith of Japan. 7. Leprocenys (LoBpopeira) KITTELI Mayr subsp. ALTISQUAMIS Forel. Three workers and an imperfect male from Hong-kong (Terry). Hitherto known only from the Thaungyin Valley, Tenasserim. 8.

Differing in its much smaller size from the typical monticola, its var. longi — Forel and its subsp. punctulatus Forel, which measure from 10-13 mm. The — WHEELER: CHINESE ANTS. 531 posterior border of the head is scarcely emarginate in the middle, the occipital furrow is distinct but there is no median furrow on the front. The inner border of the mandibles bears eight denticles, which diminish in size basally where they are very small. Of the three apical teeth the most basal is large, rectangular and slightly longer than broad. Petiole convex in front and behind with short, stout, apical spine. The body is smooth and shining, except the front which has fine, posteriorly fanwise diverging rugae, and the mesonotum and dorsum of the epinotum, which are finely, transversely rugose. The pronotum, mesopleurae, and sides of the epinotum are entirely smooth and shining like the head. The posterior portion of the latter is very indistinctly and sparsely punctate. There are only a few hairs and they are on the gula, ventral surfaces of the mandibles, and posterior portion of the gaster. Color brownish red; mandibles slightly paler; gaster of the same color as the thorax but slightly darker above behind the first segment. Legs brownish yellow. A single specimen from Mokanshan (Gee). This subspecies is both smaller and smoother than any of the described forms of monticola and seems to be a northern and probably depauperate race. Forel has described two additional varieties, formosae and major, of the same species from Formosa, but both have the posterior portion of the head distinctly striated, especially major, which measures 13.5-13.6 mm.

Mandibles with oblique, 4-toothed blades, the basal teeth separated. Clypeus bicarinate, its anterior border with two stout median and two very small lateral denticles. Frontal area small, crescentic; frontal groove distinct; frontal carinae very short. Antennae 11—jointed; scapes not reaching to the posterior corners of the head; second funicular joint longer than broad; joints 3-8 fully as long as broad; basal joint of clava about half as long as the terminal joint. ‘Thorax elliptical, robust, distinctly broader than the head; mesonotum nearly twice as long as broad; pronotum vertical in profile; epinotum abruptly sloping, short, with subequal base and declivity meeting at a rounded, very obtuse angle. Petiole somewhat longer than high, with short peduncle, furnished with a small ventral tooth at the anterior end, node from above somewhat transverse, broader than long, com- pressed anteroposteriorly. Postpetiole a little broader than the petiole, its node broader than long, very convex and rounded above. Gaster large, elliptical. Legs rather short. ; Shining; mandibles very indistinctly striatopunctate, almost smooth. Head uniformly and rather coarsely punctate, front very finely and densely longitudinally striate; remainder of body with extremely fine, sparse, piliger- ous punctures. Hairs white, very delicate, erect and abundant but rather short on the upper surface of the head, thorax, and pedicel, shorter and sparser on the gaster and appendages, somewhat oblique on the latter. Yellowish brown; head darker and more reddish above; venter, posterior borders of gastric segments, mandibles, clypeus, cheeks, and appendages _ yellow; mandibular teeth dark brown. Wings whitish hyaline, with almost colorless veins and pale brown pterostigma. Male. Length, 2.5-3 mm. Head, including the eyes as broad as long, somewhat flattened above, semi- circularly rounded behind, with very short cheeks. Mandibles slender, with three subequal teeth. Clypeus convex in the middle, without carinae, its anterior border feebly concave, edentate. Antennal scapes very short, as long as the two basal funicular joints together; first funicular joint swollen, a little longer than broad. Thorax like that of the female, but the epinotum more convex, with round, sloping base, much longer than the concave declivity. Petiole without a ventral tooth, its node very low; postpetiolar node flattened above. Legs slender. Body smooth and shining as in the female, but head without coarse punc- tures, merely finely reticulate on the cheeks and behind the ocelli. Hairs on the head, thorax, and pedicel much shorter and less abundant, those on the appendages very fine, sparse, and closely appressed. Color like that of the female, body and head a little darker. Wings as in the female. Described from numerous specimens of both sexes taken at Soochow by Prof. N. Gist Gee. : WHEELER: CHINESE ANTS. 533 This species is evidently closely related to the common Eurasian L. fugax Latr., but is certainly distinct. The female of the latter species is considerably larger (4.7-6 mm.), darker, with much less shining head, thorax, and pedicel, with the thorax almost as coarsely punctate as the head, the epinotum more projecting, with very dis- tinct base and declivity, a much shorter peduncle to the petiole, shorter median funicular joints, darker wing venation, sparser and more bristly hairs. The male fugax is also larger than the male soochowensis, much darker and more pilose, with the head, through the eyes, broader than long, finely rugulose and subopaque. In size, sculpture, and color of the two sexes and in the shape of the female epinotum and color of the wings the Chinese species is much more like the common Nearctic S. molesta Say, but the petiole and post- petiole of the female molesta are very differently shaped, the thorax is much narrower and more elongate, the pilosity is coarser, the head of the male is more narrowed and less rounded behind and the an- tennal scapes are decidedly shorter. 14. PHEIDOLOGETON DIVERSUS (Jerdon). A soldier and female from Hong-kong (Terry) and two soldiers from Macao (Muir). A common and conspicuous ant throughout India, Burma, the Malayan Region, and the Philippines. 15. PHEmOLOGETON AFFINIS (Jerdon). Several soldiers and workers from Hong-kong (Terry). Witb much the same distribution as the preceding species. 16. PHEIDOLOGETON VESPILLO, sp. nov. Worker maxima (?). Length, 3.5 mm. Head rectangular, slightly longer than broad, with straight, parallel sides and very feebly excised posterior border, evenly convex above and below in profile. Eyes very small, flat, consisting of about 7-10 minute ommatidia, situated about 2 the distance from the anterior corners of the head. Mandi- bles convex, with five blunt teeth, the two at the apex larger. Clypeus convex in the middle, with a pair of blunt, anteriorly diverging ridges, narrow and depressed on the sides, the anterior border sinuately notched in the middle. Frontal area small and indistinct, at the anterior end of a small elongate triangular impression. Frontal groove and carinae short, the latter diverging 534 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. posteriorly. Antennae slender, the scapes reaching a little beyond the an- terior half of the lateral border of the head; funicular joints 2-6 as long as broad, joints 7 and 8 longer than broad; basal joint of clava j as long as the terminal joint. Pro- and mesonotum in profile very convex, rounded, hemi- spherical, without promesonotal suture, from above half as broad as the head, as broad as long, narrowed behind to the deep mesoépinotal constriction. Epinotum short, its base straight in profile and shorter than the sloping declivity, with a pair of erect, flattened teeth which are as long as broad at the base and curved forward and outward. Their bases are continued as a pair of anteriorly converging ridges on the base of the epinotum and posteriorly as a pair of parallel ridges down the sides of the declivity. Petiolar node small, angular in profile, with both the anterior and posterior slopes straight, its ventral outline evenly convex. Postpetiole large, three times as broad as the petiole, as long as broad, slightly narrower in front than behind, evenly rounded and convex above, but not higher than the petiole. Gaster smaller than the head, with straight anterior border. Legs rather long. Very smooth and shining. Mandibles with a few small, very sparse punc- tures, their bases striated. Sides of clypeus, cheeks, and space on each side medial to the frontal carinae longitudinally striated. Mesopleurae and epinotum subopaque, the former very finely punctate-rugulose. Hairs golden yellow, very sparse, erect, and rather long on the dorsal sur- face of the body, on the legs more numerous, fine and aDPrPSeeR Red; gaster and legs yellow. Worker minima. Length, 1.5-1.8 mm. Resembling the large worker, except in the small size of the head, which is more distinctly longer than broad, with more convex sides and more rounded posterior angles. Eyes smaller, a little in front of the middle of the sides. Mandibles, pro- and mesonotum less convex, the apical margins of the former oblique, with more acute teeth. Teeth of epinotum very small and slender, directed upwards. Sculpture, pilosity, and color as in the larger worker. Described from nine maxima and two minima workers from Mokan- shan (Gee). Some of the former are almost intermediate in the size of the head between the two extremes. I am not certain that the largest really represent the maaima of this species which is closely related to such small Pheidologetons as nanus Roger of India and especially to yanot Forel of Formosa. 17.

Antennae slender; scapes extending scarcely more than } their length beyond the occipital border of the head, at the base furnished with a flattened lobe resembling that of the North American A. treaiae Forel, but smaller; all the funicular joints decidedly longer than broad, the terminal joints not forming a distinct clava. Thorax slender, narrower than the head, with pronounced mesoépinotal constriction. Pronotum and anterior portion of mesonotum forming together a hemi- spherical mass, with evenly rounded dorsal and lateral surfaces; posterior portion of mesonotum sloping backward to the short mesoépinotal constric- tion. Epinotum longer than broad or high, its base horizontal, feebly and evenly convex in profile and much longer than the vertical declivity, armed with two rather acute spines, which are scarcely longer than broad at the base and directed upward, backward, and outward.

Extreme base of first gastric segment above opaque, finely and densely punctate. Legs and remainder of gaster very smooth and shining, with very sparse, minute, piligerous punctures. Hairs on the body yellowish, moderately abundant, coarse, and erect, not longer nor more abundant on the gaster than on the head and thorax; more numerous, shorter, finer, and subappressed on the scapes and tibiae. Castaneous red; upper surface of head, except behind and in front, blackish; gaster black, except its tip. The latter, the trochanters, and bases of the femora more yellowish. Female. Length, 9-10 mm.; wings, 10—10.38 mm. Head, excluding the mandibles, scarcely longer than broad, distinctly broader behind than in front, with distinct, though rounded posterior corners. Antennae with the scapes lobed at the base as in the worker, but reaching only about + their length beyond the posterior corners. ‘Thorax very robust, broader than the head and as high as long. Epinotum steep, with distinct basal and declivous surfaces and with very stout, straight spines, which are distinctly longer than broad at their bases. ~Petiole and postpetiole similar to those of the worker, but stouter, with their nodes more compressed antero- posteriorly and each bearing a small, blunt tooth at the anterior end on the ventral surface.

Mandibles with oblique WHEELER: CHINESE ANTS. 537 apical borders bearing two larger terminal and three or four minute basal teeth. Clypeus with entire, broadly rounded anterior border. Scapes of antennae very short, not longer than the first two funicular joints together, broader at the base than at the tip; funicular joints all longer than broad. Thorax resembling that of the European A. gibbosa Latr., but more extreme, the poste- rior extension of the epinotum being nearly as long as the more anterior portion of the thorax and the constriction separating the two being more pronounced. The epinotal spines are reduced to a pair of minute teeth. Mesonotum extremely convex, in profile with a vertical, rounded, anterior and horizontal, rounded posterior surface. Nodes of the petiole and postpetiole very low, the peduncle of the former cylindrical, constricted anteriorly, the post- petiole campanulate. Gaster subtriangular. Legs, including the coxae, very slender, the middle and hind femora sinuately bent. Smooth and shining; head opaque, finely and densely punctate, slightly shining about the ocelli.

Gist Gee, to whom the species is dedicated. Also workers from Foochow. It is related to the Japanese A. famelica F. Smith, of which only the worker is known. This form is more brownish and less reddish, smaller and more slender, with longer head and antennae, and the scapes have no lobe at the base; the sculpture is feebler, the head behind and the pronotum, petiole, and postpetiole are smoother and shining, the transverse rugae on the base of the epinotum are more pronounced and the epinotal spines are smaller and more erect. The pro- and mesonotum above are not so high and rounded as in geet. The work- ers of the latter were compared with three workers of famelica from Saitama, Japan, in my collection. 22. APHAENOGASTER EXASPERATA, Sp. NOV. Worker: Length, 5.5-6 mm. Head oval, without. posterior corners, less than 13 times as long as broad, with marginate occipital border.

Petiole rather small, twice as long as broad through the node, which is shorter than the peduncle, conical above and constricted behind. Postpetiole pyriform, longer than broad, somewhat less than twice as broad as the petiolar node, the node feebly convex anteriorly in profile and distinctly concave behind. Gaster rather large. Legs long and slender. Middle and hind tibiae with distinct but slender spurs. Shining; mandibles subopaque, very finely and sharply longitudinally striate. Head coarsely and sharply reticulate rugose, the rugae diverging on the front, those starting from the anterior corners making a sigmoidal curve, bending outward around the antennal foveae, turning inward around the inner orbits and then laterally again. Neck finely and transversely rugulose. Thorax coarsely rugulose like the head but less strongly and more irregularly. Pronotum above smooth and shining in the middle, on the sides finely and longitudinally striate. Base of epinotum strongly and rather regularly trans- versely rugose, the concave declivity with similar but feebler sculpture; mesopleurae and sides of epinotum more irregularly punctate-rugose. Petiole and postpetiole smooth and shining, except their ventral surfaces which are subopaque and very finely and densely punctate. Gaster smooth and shining, the basal third of the first segment subopaque and very finely and densely striolate. Hairs yellow, coarse, obtuse, moderately long and abundant on the body, much finer and more appressed on the legs, especially on their flexor surfaces. Dark reddish brown; legs, including the middle and hind coxae, the tip of the gaster, and the posterior margins of its segments brownish yellow; mandi- bles, neck, sides of pronotum, fore coxae, and antennae red; apical halves of femora infuscated. Described from eighteen specimens taken by Professor Gee at Mokanshan. . This species is very distinct, being quite unlike famelica and geet. In certain respects it resembles A. rothneyi Forel of India and central China and especially its subspecies t?puna Forel of Formosa. WHEELER: CHINESE ANTS. 539 23. MOoONOMORIUM PHARAONIS (Linné).

MyRrMECINA GRAMINICOLA (Latreille) subsp. SINENSIS, subsp. nov. Worker. Length nearly 2.3 mm. In size and color closely resembling the subsp. nipponica Wheeler of Japan but differing in the following particulars: — Head with more rounded sides and posterior corners. Clypeus completely lacking the teeth which are so prominent in the typical European graminicola and even in the Japanese form. The anterior border of the clypeus is merely rounded and sinuately emarginate in the middle. The epinotal spines and teeth are much as in nipponica, but the sculpture and pilosity are different. The mandibles are opaque and very finely shagreened; the rugae of the head and thorax are much less pronounced and the surface is more opaque. The hairs on the dorsal surface of the body are much shorter and distinctly more appressed, especially on the gaster. Described from two specimens from Mokanshan (Gee). 26.

LIOMETOPUM SINENSE, sp. nov. Worker. Length, 3.3-4.5 mm. Head large and broad, as broad as long, very broad behind, narrowed in front, the anterior corners not swollen and prominent. Mandibles moder- ately convex, with four large apical and five or six smaller basal teeth. Cly- peus rather flat in the middle, ecarinate, with straight, transverse anterior border. Eyes flattened. Frontal area and frontal groove obsolete. Frontal carinae subparallel, diverging only at their extreme posterior ends. Antennal scapes scarcely reaching beyond the posterior corners of the head; funicular joints 1-6 distinctly longer than broad, joints 7-10 as broad as long, terminal joint as long as the two preceding joints together. Thorax narrower than the head; with distinct promesonotal and mesoépinotal sutures; in profile with the dorsal outline straight, gradually sloping backward from the anterior end of the mesonotum to the epinotal declivity, which is a little shorter than the base of the epinotum, feebly convex and more steeply sloping. Petiolar node — in profile cuneate, not very thick at the base, inclined forward, narrowed and gradually compressed anteroposteriorly, above with narrowly rounded but rather acute border. Gaster large and somewhat flattened dorsoventrally. Legs moderately long and stout. Shining; very finely and densely punctate-shagreened; mandibles sparsely and evenly punctate. Hairs and pubescence pale yellow, the former very delicate and sparse, rather short and of uneven length. Pubescence very short and delicate, closely appressed on the head, thorax, petiole, and appendages, and so dilute as not to conceal the sculpture; on the gaster longer, denser, and coarser, diverging from the middorsal line posteriorly on the first segment and strongly converging towards this line on the second and third segments. Reddish brown, gaster dark brown, with the posterior borders of the seg- ments brownish yellow; mandibular teeth black; tarsi yellowish; tips of tarsal claws dark brown; femora, except their bases and tips, darker than the tibiae. ; WHEELER: CHINESE ANTS, 541 Described from eighteen specimens taken at Soochow by Professor N. Gist Gee. Resembling L. lindgreent Forel of Assam and Burma in color, but the head in this species, judging from a cotype received from Pro- fessor Forel, is decidedly smaller and narrower behind, the eyes are much more convex, the antennal scapes extend nearly § their length beyond the posterior border of the head, the petiolar node is lower and thicker, and the hairs and pubescence are longer and less ap- pressed, especially on the tibiae and antennal scapes. On these parts, in fact, the hairs are abundant and suberect. The pubescence on the gaster seems to be somewhat sparser than in sinense and seems not to converge or diverge but to be directed uniformly backward on all the segments. ‘The specimen is rather greasy, however, so that I am in doubt in regard to this character. Forel makes no statement con- cerning the arrangement of the gastric pubescence. The South European L. microcephalum Panzer is more like sinense in the size of the head, but it is not so broad and its anterior angles are conspic- uously swollen, the thorax is more convex and arcuate in profile, the petiole is more acuminate above, and though the pubescence on the gaster is similar in texture and arrangement, the erect hairs on the head and thorax are longer and more abundant. The color of the body is very different. 31. LIoMETOPUM SINENSE var. SERICATUM, var. nov. Worker. Differing from the typical sinense in having somewhat larger eyes and the anterior angles of the head more protuberant, in the less reddish and more fuscous tint of the body and in the pubescence, which is much finer and denser, especially on the gaster so that the surface is completely concealed. The pubescence is also more silky and more yellowish.
