In the robust stature , the shape of the head , the long flexible terminal joint of the palpi and the neuratiou of the wings this new genus agrees with Ctejiophora , but it may be distinguished by the antennae , which in both sexes are strongly enlarged on one side and somewhat sawlike. Face conically prolonged downwards and extended to a sharp point; eyes round, slightly prominent. Antennae stout , composed of thirteen joints , with exserted hairs ; the two basal joints as in Ctenophora ; the third and following ones slender at the base , and enlarged into a broad knob towards the underside , in consequence of which the antennae have a sawlike appearance; the apical joint subulate. Palpi four-jointed ; the terminal joint as lojig as the three prece- ding taken together. Thorax convex ; pronotum distinctly separated. Abdomen oblong, composed of eight segments ; genitals of the male but little swollen. Legs stout ; ti- biae , at least the hind ones , with short spurs. Wings as long as the abdomen; the second posterior cell sessile. 12. Prionota nigriceps ^ n. sp.

Head , including the palpi , black or blackish-brown. Antennae of the cf at least as long as the head and tho- rax together ; those of the 9 hardly half as long ; the two basal joints and the short stem of the following joints reddish-yellow ; the broad knob of the latter black ; the exserted hairs yellow. Thorax and scutellum ferruginous , opaque, with short pilosity of the same colour; pleurae darker, especially in the cT. Abdomen of the cf red- dish-yellow on the three first segments; the following ones and the genitals black; first segment short; second very long, with a narrow black lateral stripe; the following segments gradually decreasing in length (in the female Notes from the Leytlen Bluseuin , "Vol. A-'II.

In the Leyden Museum are two specimens , one from Java (Macklot), the other from Halmaheira (Bernstein), which I consider to belong to this species, though the description of Wiedemann does not agree in all points. The colour, which he calls »gemsleder-braunlich", in these specimens is rather pale ferruginous , the brown longitu- dinal stripes on the thorax, mentioned by him, are only faintly indicated. Macquart has already remarked that Wiedemann was mistaken in considering his specimen , which had exceed- ingly long antennae, a female, for, in the genus Me- gistocera this is exclusively a character of the male. The two above mentioned specimens of the Leyden Museum are also males ; in the one from Java the antennae are present, but the abdomen is broken off; in the one from Halmaheira the contrary is the case. It will be easily understood , that insects of such tender structure do not often reach us in good condition. The first joint of the antennae is cylindrical, very thick and as long as the face; the second joint is short and knotty; then follows an extremely long, hairlike flagel- lum , the three or four first joints of which only are set off by a rather inconspicuous knot. The head and thorax have a dense and rather long pilosity. The abdomen is Notes fvom tlie Leyden Mlixseum, Vol. VII. 4 MEGISTOCERA FUSCANA. proportionately very sliort. The wings pure hyaline, even along the costa, and more than twice as long as the ab- domen ; the veins and the very distinct stigma are tes- taceous. The neuration agrees chiefly with that of Tipula and Ctenopliora ; the upper basal cell is longer than the two others; the middle basal cell does not quite reach the discal cell, but is separated from it by a small pedi- cle ; the two subcostal cells are large , the inner one some- what triangular, the cubital cell is also broad, especially at its base ; the discal cell on the contrary is very small , trapezoidal ; the first posterior cell is narrow in the mid- dle , in consequence of a sinuosity of the longitudinal veins which limit it ; the axillar vein is very short *). 14.

Besides the many Javanese specimens, existing in the Leyden Museum or in my possession , I have seen specimens of it from Su- matra (v. Lansberge) , from Gorontalo (v. Rosenberg) and from Obi (Bernstein). Most of the specimens , which I examined , exactly agree with the description of T. castanea Macq., which must be considered merely as a variety of T. umhrina. The an- tennae are just as Macquart describes them. According to him, the difference principally exists in the absence of the brown stripe on the metanotum and of the white transverse band on the wings. In fact there are only a 1) With regard to the nomenclature of the neuration see //Tijdschrift voor Entomologie"' XIV. p. 97. jNTotes from the Leyden ]Vluseura, "Vol. VII.

Besides the specimens which agree in all respects with the description given by Wiedemann , I find in the Ley- den Museum others , which differ in some minor points and therefore must be considered as mere varieties. A male specimen from Ambarawa in Java (Ludeking) has the thorax entirely black ; the stripes of the abdomen likewise are black, that of the upper side is enlarged at the hind margin of each segment , and the last segments are totally black. This is the variety mentioned by Mac- quart in the 3''^i supplement of his „Diptères exotiques". In another male specimen , also from Java (Muller) , the black colour of the abdomen is .still more extended , so that there remain only two yellow lateral stripes. In both these varieties the legs are not darker than in normal specimens. 24. Eriocera alhipunctata , v. d. Wulp. Tijdschr. v. Entom. XXIII. 158. 6. pi. 10, f. 3 and 4. Notes from the Leyden Muserum , Vol. "VU. 12 ERIOCERA ALBIPUNCTATA, My description (/. c.) only refers to the Q. In the Ley den Museum are a few male specimens from Java (Muller and Blume) , which seem to belong to this spe- cies, though in most of them the white tip on the wings is absent, so that the name, which I have given to the species, appears to be derived from an inconstant cha- racter. In the specimens referred to the abdomen is bright reddish-yellow , with the incisions and narrow lateral stripe black ; the hind margin of the fifth segment is black, pointed towards the front; the sixth segment is black , on both sides with a pair of yellow spots close to each other ; the last segment and the genitals are entirely black. The wings are less dark and more brownish-yellow than those of the female described; hence the white spot on their tip, if it is present, is not so distinct. 25. Eriocera Hilpa^ Walk.

Wings dark brown , the hind margin beneath the anal vein greyish; beyond the middle, but before the discal cell, is a large white spot, which is limited below by the postical vein and above is angularly bent towards the apex a little before the small cross- vein , which unites the subcostal vein with the upperbranch of the radial vein ; almost above this cross-vein is a small white spot; there are also greyish spots in some of the cells; the wings have but four pos- terior cells. Notes iroin the Leyden AXuseum , Vol. "VII. ERIOCERA HILPA. 13 Another specimen received from the same source, per- haps the cf , — but of which the abdomen is broken off, — has only the above mentioned white spot beyond the middle. E. lemostola Walk, (Proc. Linn. Soc. Lond. I. 6. 5), from Singapore, seems to be closely related to this species but differs in having a white tip to the wings. As we have seen in the foregoing species , this character is not constant. E. leucostola may perhaps be the same species as E. Hilpa. 26. Eriocera ferruginosa , n. sp.

Thorax yellow, with three broad, black, longi- tudinal bands on the upper side , the outer ones shortened and somewhat narrower in front ; pleurae with two oblique fuscous bands ; scutellum brownish-red ; metanotum greyish- yellow, shining. Abdomen too much damaged for des- cription. Legs reddish-yellow; the tips of the tibiae and of the two basal joints of the tarsi fuscous ; the following joints of the tarsi entirely of this colour; the hind legs are longer and stouter than the others ; the dark markings are more extended and black ; the femora have a broad fuscous ring in the middle and a black tip ; the tibiae and first joint of the tarsi are fringed on the outside with a dense pilosity. Wings shorter and broader than in our European species , clouded and with about four fuscous spots : a small quadrate one at the root of the radial vein and three larger ones at the costa, the first at the end of the auxiliar vein , a second between the end of the subcostal and radial veins, the third, which is the largest, at the apex of the wing. A cT from Ardjoeno in Java (Hekmeyer). Although this unique specimen is somewhat damaged and therefore the description incomplete , I do not hesitate to publish it, because up to the present time no species of Rhyphus has been described from the Sunda Islands; moreover, this species will easily be recognized by the markings of the wings.

ON DIDELPHIS CAUDIVOLYULA KERR AND DIDELPHIS VULPECULA KERR. Dr. P. A. JENTINK. Nov. 1884. Some montlis ago I was happy enough to procure for our library the rare Animal Kingdom written by Kerr. This author described clearly two Phalangers under the na- mes New-Holland Opossum and Vulpine Opossum: these descriptions have been overlooked by all the naturalists who have studied the Phalanger-group. As the specimens of these two species are greatly va- rying in color, and these varieties have been described as species , I will try to give a synonymy as complete as possible and to describe in short terms the individuals in our collection in order to give the reader an impression of the variation in color of the species in question. The species quoted belong to two distinct genera, cha- racterized as follows: Pseudochirus : Phalangers with the two inner toes of the fore foot separated from and partially opposable to , the other three : the tail clothed , excepting at the apex beneath , with short adpressed hairs. The ears short and rounded (Waterhouse, Marsupiata. I. p. 297). Trichosurus : Tail densely clothed with fur , with the exception of a part of the under surface, commencing at Notes from the Leyden ]Museum, Vol. VII. 22 PSEUüOCHIRUS CAUDIVOLVULUS. the point, and more or less extended towards the root of the tail: ears distinct, usually long: fore feet normal (i. e. with no marked separation of the two inner from the three outer toes).

Vol. I. p. 305, 1863. Pseudochirus lanuginosus. Gould. Mammals of Australia. Kerr described the species as follows: » Inhabits New- Holland , near Endeavour-river. The head and body are about thirteen inches long, being covered on the upper part and the sides with long, soft, glossy hairs, of a dark cinereous colour at the roots , and rusty brown at the ends ; the tail is taper and of the same length with the head and body; two-thirds of its length is covered with short brown hair , the extremity being white , and naked under- neath ; the paws are furnished with thumbs having flat nails , and the toes have short claws : This species lodges among the long grass, but is little known. The tail is taper, hairy and prehensile at the end". Now I proceed to register the specimens of this species in the Leyden Museum , adding short diagnoses, 1. Adult male. Australia, Clarence river. From Stran- ge's voyage. Rusty colored, mixed with black on the back; underparts bright rusty, ears behind similarly colored, 2. Nearly fullgrown male. Australia. Frank, 1845. Like Notes from the Leyden Mliiseum , Vol. "VII. PSEUDOCHIRUS CAUDIVOLVULUS. 23 N°. 1 , but upperparts of head and tail blackish , back grizzled and uuderparts of body brighter. 3. Nearly fullgrown male. Australia, upperparts sooty- grey; head above, outside of legs and tail light rusty; ears behind , underparts of head and of body and inside of legs pure white. 4. Nearly fullgrown male. Australia. Frank, 1845. Head above, back, sides of body, upperhalf of legs and tail dark mouse grey ; lower half of legs externally and a cir- cle round the eyes light rusty; ears behind, underparts of body and of head and inside of legs pure white. 5. Female, mother of N"». 6 and 7. Australia, 1870. Colored like N». 4. 6 and 7. Young specimens. Upperparts generally darker than in N". 5 , outside of legs lighter. Circle round the eyes dark rusty. For the rest like the mother. 8. Young individual. Australia. Colored like the former young specimens. 9. Adult female, described by Temminck (Mammalogie. I. p. 7). According to the named author this specimen is one from Cook's voyage. Now I find that in Cook's account there is only question of two individuals , viz : a female from Endeavour river (1770) and a male from Van Die- mensland (1777). Temminck says that the /maZe-specimen in the Leyden Museum is from van Diemensland and from Cook's voyage, meanwhile Cook's ma/e-specimen from Van Diemensland was »the only animal of the Quadruped kind they got". My conclusion therefore is that Tem- miuck's specimen either is from Endeavour river or is not one of the two specimens of Cook's voyage. It is colored like No. 4, except the circle round the eyes which is darker. 10. Adult female. Van Diemensland. One of the spe- cimens described by Ogilby in 1837 s. n. Phalangista viverrina. Head above, back and sides of body, tail and outside of legs dark ashy brown ; ears behind , underparts of head and body and partially the inside of legs pure white.

Kerr described this species ia the following terms: »The tail is long , thick and hairy : for three quarters of its length it is black , and the origin is of a greyish colour , like the body. Inhabits New South Wales. — The head and body measure twenty-six inches , and the tail fifteen ; the legs are short and of an equal length ; the foot is long , and rests in walking as far as the heel ; each foot has five toes , all armed with sharp crooked claws , except the thumb , or great toe , on each hind foot , which is placed high up on the foot, and has no claws; the head is long, with a pointed muzzle, which is garnished with ten or twelve very long black whiskers , which stand backwards , and are longer than the head ; the ears are long , erect , and pointed ; the upper jaw has four fore-teeth , and the lower two , which point forwards , both being like those of the Kanguru ; on each side , in the upper jaw , are two small tusks , but none below ; there are four grin- ders on each side in both jaws. The whole upper parts of the body, and first quarter of the tail, are of a grisly colour, proceeding from a mixture of dusky and white hairs ; with a reddish-yellow tinge , chiefly on the head and shoulders; the rest of the tail is black; all the under- parts of the body are of a tawny buff, which is deepest on the throat, where the bottom of the hairs is rusty brown". Phalangista xanthopus Ogilby has the tip of the tail white , but this alone is not enough to create a new spe- cies , moreover Ogilby says » that in all other respects it is most closely allied to the PhaL vulpina.''^ One of our in- dividuals has the tip of the tail white (vide infra No. 3). Phalangista canina Ogilby has shorter ears according to that author , but I find in Gray's List of the Specimens of Mammalia of the British Museum, 1843, p. 85, that the specimen described by Ogilby has the ears injured. The other differences between Ph. canina and Ph. vulpina Notes frona the Leyden M.iiMeum, Vol. "VII. TRICHOSURUS VULPECULA. 27 summed up by Ogilby are merely difiPerences in color aud have here no specific value (vide infra N^. 1). For the rest I refer to what I said in my paper (Notes from the Leyden Museum, 1884. p. 108). Our specimens present the following variations in color: 1. Adult female. Australia. Above greyish black tinged with coffee-brown , end of tail black ; underparts white, each hair greyish brown at its base; ear-patch coffee-brown. This specimen was labeled Phalangista canina Ogilby and indeed its ears are conspicuous short; a nearer inspection however shows that the ears are injured. The skull and teeth present no differences with the same parts in the other specimens. 2. Adult male. Australia, neighborhood of Melbourne. Zoological garden at Rotterdam, February 1881. Above greyish black , end of tail black ; underparts and ear -patch reddish yellow ; a rusty brown mark on the chest. 3. Adult female. Australia, Swan-river. Verreaux. La- beled Phalangista xanthopus Ogilby. Colored like the for- mer , but underparts white like N°. 1 , ear-patch very in- conspicuous , apex of tail pure white. 4. Adult male. Australia. Frank, 1844. Labeled Pha- langista felina Wagner. Upperparts rusty red; hindparts of back with blackish , end of tail black ; underparts yellowish white, each hair rusty at its base; on the chest an elon- gate rusty brown mark; ear-patch very inconspicuous. Skull and dentition entirely like the other skulls. 5. Adult female. Australia , Swan-river. Verreaux. Colored like N°. 1 , but less dark. Ear-patch white and a rusty brown stripe on the chest. 25. FuUgrown male. Australia. Colonial Museum , Haar- lem, 1875. Upperparts greyish rusty; end of tail rusty black ; underparts orange brown ; a rusty brown stripe on the chest ; ear-patch yellow brown ; feet yellow brown. 6. Nearly fullgrown male. West-Australia. Labeled Pha- langista felina Wagner. Colored like N°. 4; end of tail dark reddish black, ear-patch white. Notes from the Leyden IVIuseuixi, "Vol. VII. 28 TRICHOSURUS VULPECULA. 7. Young male. Australia. Upperparts of a beautiful fine chocolate tinge, end of tail blackish brown; underparts white, the base of the hairs like upperparts; chest-mark inconspicuous, ear-patch white. 8. Young female. Australia, neighborhood of Melbourne. F. Muller, 1865. Colored like N°, 2; no mark on the chest. 9. Very young female. Australia , 1873. Upperparts greyish black ; end of tail black ; underparts , ear-patches , hands and feet white. 10' Adult male Van Diemensland. Type specimen of Temminck's Phalangista vulpina (Mammalogie, I. p. 5). Upperparts brownish grey , base of tail like back , for the rest black ; underparts rusty yellow ; a rusty brown mark on the chest; ear-patch dirty white. 11. Adult female. Van Diemensland. Voyage of Lewis. Upperparts rusty black, darker towards the hind part of the back ; tail black ; underparts rusty brown. 12. Adult female. Van Diemensland. Verreaux. Colored like the former; ear-patch brownish black. 13. Nearly fullgrown female. Van Diemensland? Colored like the former , but less dark. 14. Younger male. Van Diemensland. Frank Upper- parts and tail brownish black; underparts brownish with a reddish shade; a rusty brown broad mark on the chest. 15. Very young male. Van Diemensland. Colored like N°. 9; mark on chest hardly visible. We possess nine skulls of this species and the skeleton of N°. 2. The latter presents 13 costales, 6 lumbares, 2 sacrales and 25 caudales. Remark. Mr. Oldfield Thomas of the British Museum fixed the attention of the naturalists to Kerr's Animal Kingdom (Annals and Magazine of Natural History, 1879, 5th series , Vol. IV, p.p. 396 and 397). Mr. Thomas stated that Phalangista vulpina Shaw is a synonym of Didelphis vulpecula Kerr. Notes from the Leyden ]Mviseixm, Vol. "VII. PLATYNEMA OLLIFFI. 29 NOTE V. DESCRIPTION OE A NEW SPECIES OF THE NITIDULID GENUS PLATYNEMA, RITS. (ORTHOGRAMMA , MURRAY') nec GUENÉE). C. RITSEMA Cz. Of this species I have seen three specimens, captured in the Andaman Islands, and of these Mr. A, Sidney Ollifif has been good enough to let the Leyden Museum have two; I therefore propose to call the species Platynema Ollijffi. Length 4,5 mm. — Elongate, subparallel, gradually widening a little towards the middle of the abdomen, de- pressed , shining , dark piceous with tinges of purple , green and blue, which are more conspicuous on the tho- rax than on the head , elytra and abdomen ; the part of the head before the eyes, as well as the two basal joints of the antennae rufous; the extreme lateral margins of the thorax narrowly testaceous; the elytra testaceous , pass- ing into dark brown at the sides and into piceous at about two thirds of their length ; the apical margin of the abdominal segments narrowly testaceous ; the legs dark brown , brighter at the knees ; the tarsi pale testaceous. 1) This generic name, which dates from the year 1864, cannot be retained, as Guenee had already used it in 1852 in the Lepidopterous family Noc- tuidae. I therefore propose to substitute Murray's name by Platynema (from 7r?iXTVi; , flat, and vsj//a, a thread). Notes from the Xjeyden IMuseum, "Vol. "VII. 30 PLATYNEMA OLLIFFI. The head of about the same length as the thorax; the sides behiud the eyes slightly convex , parallel ; epistome with two projecting slender teeth which are divergent and slightly directed downwards ; the angle between the teeth is rounded; the head is flat or even faintly impressed on the disk , and covered with a strong but rather distant punctuation. The sides of the thorax , which is a little narrower at the base than in front and widest about the middle where it is wider than the head , are regularly convex ; the an- terior angles declinate , the posterior ones broadly rounded and provided with a small impression ; the disk is flat and provided along the middle with a large ovate very shallow impression , which extends from the front margin to the base ; an excessively fine mesial line may be observed at the bottom of this impression ; the impression is rather more distantly punctured than the head; on the sides of the thorax the punctures are more close together and elon- gate. Scutellum triangular, strongly transverse , impunc- tate or with a very few large punctures. Elytra distinctly longer than , but scarcely so broad as the thorax, the sides parallel, the apex conjointly round- ed , the sutural region depressed. They are punctate- striate, but the striae disappear before the apex. Abdomen distantly punctured , the third segment with a shallow central impression ; the pygidium raised along the middle. Some long testaceous hairs are present along the sides of the abdomen and on the pygidium. No doubt this species will prove to be closely allied to fuscipennis Murr. from Sarawak (Borneo) and to denticeps Murr. from Singapore. Up to this time no species have been described in this genus, besides those described by Mr. Murray and enu- merated in the 3rd volume of the Catalogus Monacensis. Leyden Museum, November 1884.

Long. 40 mm. ; lat. ad liumeros 15 mm. — Caput aureo- viride, forti ter punctatum, inter oculos bisulcatum, vertice canaliculato. — Thorax viride-cupreus utrinque macula rufa notatus , 7iitidus , leviter punctatus , convexus ^ disco linea laevissima longitudina liter impressus , apice hisinuato , lateri- hus productis paulo post medium , hasi profunde bisinuaia , lobo medio valde elongato. — Scutellum parvum , transver- sum , reniforme. — Elytra cyaneo-viridia, violace-interniten- tia , in medio fascia lata flava ornata , subparallela , apicem versus angustata , subconvexa , punctato-striata , interstitiis tenuiter punctatis , apice utrinque fortiter bispinoso. — Subtus vifidis , nitidus , abdomen flavum , (f segmenta marginibus viri- dibus , Q segmenta tertia et quarta prorsus viridia , pedes virides. Head golden-green, deeply punctured, with two curved grooves between the eyes , and with an impressed line along the vertex. Antennae bronzy-green, except the golden- green basal joint. Thorax shining, bright golden-green, on each side with a large red spot , which does not join the frontmargin and leaves a punctiform green spot just within its limits; the line of demarcation between the red and golden-green co- J«Jotes from the Leyden IMuseuxu, Vol. VII, 32 CALODEMA RIBBEL lour has an oblique direction ; both spots are also visible on the undersurface. Strongly transverse , widest behind the middle , angularly convex in a transverse direction , finely and rather distantly punctured , with a slightly impressed mesial line. Anterior margin deeply bisinuate, about half as long as the base; sides strongly diverging in straight lines till behind the middle, then suddenly converging to the base ; base very deeply bisinuate , with a narrow elon- gate median lobe. — Scutellum green , strongly transverse , semi-lunate , impunctate. Elytra dark steel-blue , with green and purple tinges , and with a broad transverse yellow band across the middle. Slightly convex , nearly twice as long as broad at the base where they are lobed, the sides subparallel, narrowing in curved lines behind the yellow band; the apex of each elytron bi- emarginate and bidentate , the sutural emargination small and very oblique. Deeply punctate-striate , the interstices convex , finely punctured, much more strongly between the 1^^ and 8th striae , and at the shoulders where the punctures be- come confluent, so as to give a rugose appearance. Beneath shining green , the sides of the breast strongly and closely punctured. Abdomen very finely punctured; in the male yellow , the segments bordered with green , the apical one semicircularly eraarginated in the middle; in the fe- male yellow , with the S''^ and 4*^ segment green. Legs golden-green. Although this beautiful species differs in some points, especially in the shape of the thorax and scutellum, from the two other described species, I do not believe the crea- tion of a new genus necessary or desirable. Of the six specimens , captured at Ureiuning (Aru Islands) by Mr. 0. Ribbe (to whom I dedicate the species), one Q is now in the collection of the Leyden Museum and an- other example of the same sex in that of the author. Amsterdam, November 1884. Notes from the Leyden IMuseum, "Vol. VII. HAPALEMUR. 33 NOTE VII. ON SOME RARE AND INTERESTING MAMMALS. Dr. P. A. JENTINK. Dec. 1884. Hapalemur griseus and Hapalemur simus. (Plate 1 and 2). lu the Proceedings of the Zool. Soc. of London for this year (1884) Mr. Beddard wrote a very interesting paper regarding some points of the structure of Hapalemur simus. On page 392 he says a few words touching the differences between the skulls of H. simus and H. griseus. He says that he was able to verify the late Gray's statements (with regard to the differences in the skulls of the two species) with a single exception, and finally states that it seems to him that Gray was right in believing that Schlegel's figure of the skull of Hapalemur griseus was in reality that of Hapalemur simus. Being able to settle this question it seems to me that it is my duty to fixe for a moment again the attention of the naturalists upon this matter. At the time as the late Schlegel wrote his Monographie ., entitled Simiae , our Museum was not in the possession of a specimen of Hapalemur simus and at that time Schlegel never had had a skull of the named species in his hands. I can testify this as I personally assisted Prof. Schlegel Notes from th.e Leyden IMuseuixi, "Vol. VU. 3 34 HAPA LEMUR. when he wrote the i>ame(l Monograph in 1875 and 1876. The first specimen (a skin with its skull) of H. simus reached us in the month of September 1877. Now it is evident that in 1876 there being no specimen of H. simus in our collection it may be called an impos- sibility that Schlegel's figure of H. griseus published in 1868 could be that of H. simus. The figures in question therefore belong truly to Hapa- lemur griseus ; but how could Gray and Beddard doubt of the thing? I believe that I can give a satisfying answer. The study of the figures learned me that two of them are incorrectly drawn. I have before me a series of six- teen slculls of H. griseus and not a single of the most adult ones is by no means as broad as in the figure 4 a (plate 7 of the Faune de Madagascar). Indeed in looking at that figure it makes the impression as if it has been taken after a skull of H. simus. But a closer inspection shows that it has been misdrawn and differs for the rest widely from that of B. simus. Generally a skull attains its length at a relatively early period and afterwards be- comes broader ; for instance the skull of a specimen of H. griseus from East Madagascar collected by J. Audebert has the same length as Schlegel's figure 4 a and as all our fuUgrown skulls, viz.: 61m.m. , notwithstanding the hind- most molar of upper and lower jaws are not yet developed : and in this young specimen the width of the skull measu- res 39 m.m. , meanwhile the width of the skull of the fullgrown individuals measure 42 m.m. (not 45.5 m.m. as in figure 4 a of the Faune de Madagascar). The skull of our Hapalemur simus presents the following dimensions: Length of skull 79 m.m. Width of ditto 59 » There is however another inaccuracy in one of the figu- res in the Faune de Madagascar , viz. : fig. 4 c shows no upper incisors. Our large series of skulls of different ages demonstrates that the upper incisors always are present, even I can see 3S"otes from the Leyden ÜMuseum, "Vol. VII. HAPALEMUR, 35 pretty clearly traces of these parts in the skull of a very adult specimen (perhaps that figured in the Faune). Epomophorus compius and Epomophorus gambianus. In a small collection of Mammals and Birds offered to me for sale and made by Mr. Bohndorff in Niam-Niam- land, central Africa, I found specimens of the above na- med species. The locality is very interesting as it gives us new facts to demonstrate the wide distribution of a large number of species of Mammals over Africa. Epomophorus comptus described by Allen after a speci- men collected by Duchaillu in Western Africa is repre- sented in the British Museum by a single (see Dobson's Catalogue) specimen from Gaboon ; as far as 1 am aware these two individuals were the only hitherto known. It is distinguished from all the other Epomophori by its extra- ordinarily developed second phalanx of the third finger , this phalanx being longer than the metacarpal bone of the same finger. The color and distribution of the fur have been very well described by Allen. The abdomen in our adult female presents a large yellowish white patch. N. B. The above named collection Bohndorff's contained also specimens belonging to the following species: Mega- derma frons , Herpestes leucurus , Sciurus stangeri and Sciu- rus rufo-hrachiatus. That the first and second species should live in Niam-Niam-land was to expect, the appearence however of the two AScmrws-species in that country is very interesting, for up to this time they only have been ob- served on the West-coast of Africa: cf. my Monograph of the African Squirrels in the Notes from the Leyden Mu- seum, 1882. Paradoxurus stigmaticus Temminck. This species seems to be very rare in the zoological col- lections and hitherto recorded merely from one locality , Notes from tlie Leyden IMuseum , "Vol. "VII, 36 PARADOXURUS STIGMATICUS. viz. from Borneo. Dr. B. Hagen presented a beautiful and fullgrown specimen to our Museum. It bad been collected by him in the vicinity of Tandjong Morawa, Deli, N. E. Sumatra. As the skeleton of this individual has been pre- served and is in our collection, I believe it to be not ■without interest to enter in some details , at the same time completing Temminck's description of the type ^). A well marked dark brown line runns from between the shoulders along the middle of the back as far as the base of the long and slender tail : this line is very inconspicuous in the type and perhaps therefore has been overlooked by Tem- minck. A whitish line occupies the middle of the nose. The skull agrees in many parts with that of Paradoxurus trivirgatus, but the bony palate extends still further back- wards than in that species and the first upper premolar is placed close to the canine like in P. musanga and not at a distance like in P. trivirgatus and P. musschenbroekii. Length of head and body 470 m.m. » » tail 525 » The skeleton presents 13 costales, 7 lumbares, 3 sacra- les and 38 caudales. Gymnura alba Giebel. In a paper on Gymnura ^) I pointed out that the white- colored specimens differ in several characteristics from the dark colored individuals and form a distinct species, which inhabits Borneo. I proposed to call this species Gym- nura Candida^ a name given to this form by Dr. Günther in 1876^); the only difference between Dr. Günther and myself being that he could find no specific characters and distinguished therefore the Borneo-form as a mere local va- riety, under the name Gymnura rafflesii, var. Candida^ 1) Esquisses zoologiques sur la cote de Guine'. 1853. p. 120. 2) Notes from the Leyden Museum. 1881. p. 166. 3) Proc. Zool. Soc. London. 1876. p. 425. I^otes from the Leyden IMuseum, Vol. VII. GYMNURA. ALBA. 37 meanwhile I found several structural differences which I considered to be of specific value. At present I kuow, that Dr. Giinther and I have tried to point out a thing since long known as a fact! Indeed in 1863 ^) Prof C. Giebel clearly demonstrated that the Borneo-form represents a quite distinct species : in his highly interesting argumentation, filling thirteen pages , he made out the matter in a very critical way and added two beautiful plates , one of the individual and one of the skeleton. He named the Borneo-species Gymnura alba. In consequence, Giebel's name having the priority, the Borneo-form futu- rely must stand as Gymnura alba Giebel. I see that Dobson in his » Monograph of the Insectivora" has overlooked too Giebel's paper on the subject. Dobson moreover considers the Gymnura-Yarieij (Gunther) and the (r^mnwr-a-species (Jentink) synonyms of Gymnura raffiesii. His reason we read on page 4 of the above referred work , viz. : » although the Bornean , compared with the Tenasse- » rim and Sumatran specimens , appear to be altogether lar- »ger and to have much lighter-colored fur, yet the mate- »rial in the Museums is quite insufficient to decide whether »this is due to age or race, or even to sex." This causa movens of rejecting species is quite new, but hardly can be called efficacious and is misplaced in a work of such a high scientific value as Dobson's Monograph. Ptilocercus lowii Gray. This always very rare Mammal was described in the year 1848 by Gray after a specimen from Sarawak , N.W. Bor- neo. We received a specimen from Banka collected by the late Teyssman in 1872, and in 1882 Dr. Hagen presented to our Museum a specimen in spirits from Tandjong Mo- rawa , Deli , N, E. Sumatra. This individual being in a very 1) Zeitschrift fiir die gesammten Naturwissenschaften. 1863. Bd. 22. p. p. 277—290. Taf. 1 und 2.

The skeleton presents 1 4 cpstales , 5 lumbares , 3 sacra- les and 31 caudales. The ribbs are peculiarly broad. The clavicle is well developed; the bones of the forearms and of the hind legs are separate. The form of skull and teeth has been described by Gray in a few words. I add the following remarks.

Length with mandibles 27,5 mm. , that of the left man- dible (which is a little longer than the right one) 8 mm. — Ground-color black, covered all over (with the exception however of the tip, the inner margin and the undersurface of the mandibles, the tip of the cephalic horn, and the clypeus) with a delicate brownish grey crust which does not hide the punctuation. The uppersurface of the mandibles , the margins of the thorax and of the elytra , and the scu- tellum , are densely beset with pale dirty yellow scales ; moreover very small scales are present on the whole un- dersurface, whereas a small number of larger scales are arranged in ten longitudinal rows on the elytra. The tibiae seem to be sharply edged which is caused by rows of densely set erect scales The punctuation of the head is quite similar to that of the thorax ; the punctures are round and rather large , very shallow and provided with a point in the centre. The punctures on the elytra are smaller, deeper and more regularly distributed over the surface. Notes from tlae Leyden IMuseum , V ol. "VII. 40 GNAPHALORYX PERFORATUS. The head is large, larger than the thorax; the sides are nearly straight, subparallel, inconspicuously convergent towards the base ; the ocular canthus is narrow , straight on the outside, and entire; the space between the eyes and the produced lateral angles of the thorax is flattened in a perpendicular direction ; the front margin of the head is regularly concave, perforated in the middle (above the bidentate clypeus) by a large and deep circular hole, and has the lateral angles rounded ; the vertex is provided with an elongate horn which is directed forwards, and slightly curved downwards at the tip. The mandibles are slender, about as loug as the head and thorax together, slightly curved , furcate at the tip ; the upper tooth of the furcation very blunt and curved, the lower tooth pointed and more developed in the right than in the left mandible; the fur- cation is preceded in both mandibles (of which the right one is a little shorter than the left one) by two teeth of different size ; in the left mandible the distance between these teeth and the furcation is considerably larger than in the right one, and in the latter the median or smaller tooth is only indicated by a small tubercle; on the up- persurface of the apical half of the mandibles a raised smooth line may be observed. — The prothorax anteriorly a little wider than the base of the head, the latter being more or less embayed between the anterior angles which are produ- ced and rounded; the front margin is bisinuate, the basal margin straight with rounded lateral angles ; the sides are straight, convergent towards the base. In the hind corners an oblique impression is present; it touches the basal mar- gin and is bounded laterally by two divergent ridges. The middle of the disk is flatfish. — The elytra are about as broad as the base of the thorax , and one and a half as long as broad. — The prosternum is longitudinally impressed between the coxae. The rather short anterior tibiae are armed on the outer margin with five teeth (besides the two apical ones) of which the first is very small and the second and fourth smaller than the third and fifth ; the four pos- Notes from the l^eyden DMnseuxn , "Vol. VII.

The clypeus pale golden green with a beautiful metallic hue , the raised margins black ; the remaining part of the uppersurface of the head covered with a yellow crust. — The uppersurface of the thorax covered with a similar yellow crust, with the exception of the central region where a large velvety black spot occurs , which has (at least in the single specimen before me) the shape of the head (with exerted antennae) and thorax of a large clavicorn beetle, viz. a Necrophorus '). Moreover a few black points are present on the anterior half near to the lateral margins. — 1) Perhaps the shape of this spot will prove to be variable, as the presumed antennae are formed by a conglomeration of black points.

(Plate 4, fig. 3, 3 a and 3t). With the species of the Genus Neritina , which I receiv- ed for revision from the Leyden Museum of natural his- tory , I found three specimens of this form , which Prof, von Martens, after specimens in my own collection , thought to be new and named it suhocellata ; but as far as I know it has not yet been described. With the approbation of the Conservator of the conchological department of the Museum I will now give a description. Shell nearly globular , delicately striated in the line of growth, with a few striae in the form of folds near the suture , and with microscopic spiral striae. The colour is greyish olive-green, with small blackish spots, which are rounded or triangular, sometimes flow together and vary greatly in size and number; they are mostly bordered by a very small rim of a lighter colour. The last whorl is more or less angular above and shows there from one to four spines in some examples, others are entirely spine- less, but show still traces of them on the penultimate whorl and one is quite destitute of spines. The spines are short , curved upwards and sometimes a little backwards.

Suture not deep , covered by the mar- gin of the next volution. Aperture moderate, obliquely semi-elliptical; upper margin curved, outer and lower mar- gin rounded , interior of the aperture bluish , the callosity near the muscular scar , moderately long , low ; the columel- lar plain callous above , with a narrow layer of enamel , which has the aspect of shagreen , becomes thicker towards the free edge and shows there a small sinuosity with 4 to 6 denticles, besides a few secondary ones; the sinuosity is bordered above by a much greater dentition and still higher are a few crenulations which form grooves to behind. Operculum semilunar, on the outside with very small granulations, yellowish, grey towards the outer margin and the nucleus, with a reddish rim, inside similarly coloured; of the two apophyses the rib is broad at the top , flattened , pale yellow; the other apophyse is orange-yellow, an in- termediate wall of nearly the same height connects it to the rib.

Three specimens from Besoekie , Java , in the river at Proeger; two from the same locality and one from Kema (Celebes) in my own collection , all found by Dr. Semmelink. This species has some affinities to JV. brevispina Lam., but it is smaller, more smooth than brevispina commonly is, and the colour is quite distinct, none of the specimens shows any trace of the black band near the suture , that seldom fails in A^. brevispina. The colouring reminds one the N. rarispina of Mousson , but that species is smaller and , according to the figures and description , of a much more oblique shape.
