The mandibles show, as in obesus Parry '), at the base on the outside a bluut tooth or tubercle which is absent in cor- nutus Macl. and distinctus Parry; the top of the recurved process of the mandibles is faiutly bifid which is not the case in the three allied species. The expansed sides of the head are rounded, but show a small emargination in their anterior half; in cornutus the sides of the head are entire, in distinctus strongly and widely emarginate , forming two distinct acute angles. The prothorax is provided with a distinct tubercle in the centre of the anterior margin ; the central fovea is rather small, shallow, and provided with a few large and deep punctures; the punctures on the disk are very fine and sparse, becoming larger and denser set towards the sides; the anterior lateral angles are not emarginate but slightly dilated ; beyond the dilatation the sides are slightly bent inwards , consequently the sides of the prothorax are neither straight nor parallel as in distinctus. The scutel- lum is somewhat broader than in distinctus and likewise provided with a few punctures ; the elytra are somewhat more elongate, but their sculpture quite agrees; they have likewise minutely pointed shoulders. The undersurface is strongly and densely punctured , the legs however finer and sparser. The middle- and hind tibiae have each three acute spines about the middle externally. Hah.

This species, of which I have three female specimens before me, is most nearly allied to and strongly resem- bles the type of the genus : Zonopterus fiavitarsis Hope -1). It is of the same size and general form , but the sides of the prothorax , which are distinctly bisinuate 'm fiavitarsis, are more regularly rounded in the new species. The lat- ter has moreover a narrower scutellum which is hollowed along the middle and has raised sides, whereas the sculp- ture by which it is covered is much less dense, even al- most absent at the base. The femora, which are coarsely punctured in fiavitarsis, have a much finer punctuation in the new species. But besides by these structural characteristics the two species may be at once separated by the different distri- bution of the colours on the antennae: in fiavitarsis the four basal joints and a spot at the base of the fifth , in the new species, however, the six basal joints are black. Moreover the first yellow band of the elytra is decidedly narrower in the new species than in fiavitarsis. Hah. Himalaya (coll. R. Oberthür). 1) Trans. Linn. Soc. London. Vol. XIX. p. Ill; tab.

ON A REMARKABLE SYLLIS-BUD WITH EXTRUDIBLE SEGMENTAL ORGANS. Dr. R. HORST. (Plate 1 , and plate 2, fig. 1). Among a number of pelagic Annelids, collected in the Malayan Archipelago by Mr. D. S. Hoedt, I met with some fragments of a Syllis-species , characterized as well by its large orange-coloured eyes, as by a series of distinct brown spots on each side of the body. The largest frag- ment has a length of about 13 m.m., and is composed of 47 segments ; another specimen , that seems to have an anal segment, measured only 9 m.m., the number of its segments amounting to 41. The head shows a deeply notched anterior margin , and is furnished dorsally and ventrally with two eyes of con- siderable size, resembling those of the Alciopidae; no ce- phalic processes are visible, neither tentacles nor palpi. Each foot (fig. 1) presents a dorsal and a ventral cirrus. The dorsal cirri are articulated and of a very different length, being in one segment thrice, in the other only once as long as the foot; the largest number of its arti- culations is 28. The ventral cirrus is smooth, acute coni- cal , projecting somewhat beyond the apex of the foot. The feet are furnished with a fascicle of 4 to 6 bristles of the type, common amongst the Syllidae, with an elongated terminal appendage, bifid at the tip and beset with short Notes from the Leyden Museum, "Vol. XI. 12 ON A REMARKABLE SYLLIS-BUD. hairs at the inner border (fig. 2a) ; the length of this ter- minal piece is not the same in all bristles , being in some of them one third longer as in others. Besides, the seti- gerous region of the foot possesses a dorsal tuft of long, translucent, paddle-shaped epitocous bristles; the tip of these ordinarily is bend and sometimes has a fimbriated appearance (fig. 2b). The condition of the anal region is open to doubt; in one specimen I observed an anal segment without feet or terminal cirri , but with wing-shaped processes along its lateral sides (fig. 3). In the base of each foot, except in that of the first segment, a large dark-brown coloured sac is situated, which appears to be capable of being extruded through a small opening at the ventral surface ; at least in some segments this sac was nearly totally everted , whereas in others I found only a part of it turned outward (fig. 4). The largest extruded pouch measures about 0.24 m.m. in length. Not doubting that these bodies represented the segmental organs, I tried to find out the internal openings of them. In consecpence of the transparency of the body I succeeded to recognize the internal mouth of the first segmental organ , situated in the second segment (fig. 5). This mouth has the shape of a rather large, shallow funnel, correspon- ding by a short, broad duct with the body of the pouch. The wall of this duct appeared to be composed of cells and its external surface shows a thin layer of pigment; in the posterior region of the body the segmental duct was therefore recognizable as a thin brown stripe. In transverse sections (fig. 6) each segmental pouch appeared to have a somewhat renal shape, being provided with a notch at its base ; this basal region usually is not pigmen- ted, the remaining portion of the sac beiug covered with a thick layer of dark-brown pigment, which seemed to be enclosed in an external layer of polygonal cells. The in- ternal surface (fig. 7) of the pouch is covered with a layer of high, cylindrical cells with a granular protoplasma and Notes from the Leyden Museum, "Vol. XI. ON A REMARKABLE SYLL1S-BUD. 13 of a glandular appearance ; though in some of them I could recognize a very distinct oval nucleus , the limits of the cells could not always be distinguished. Between the ex- ternal and the internal layer of cells a hyaline membrane is to be found. The internal cavity of the pouch is filled up with a mass of small granules , which are very darkly stained by the alum carmine. At first I presumed that this mass might consist of spermatozoa, which often have been met with in the nephridia of the Syllidae: however the matter could not be fixed , because I found no sexual products in the body cavity, and many of those granules appeared to me to extend into the interior of the epithe- lium cells, and therefore should be considered as the pro- duct of secretion of these cells. I regret that I cannot enter more fully into the minute structure of these curious bodies, the material being very scanty and not in too best a state of preservation, after having been for about 25 years in alcohol. In the figure 8 I have given two diagrammatical views of a segmental organ, to illustrate the supposed manner of extrusion of this organ ; I presume that by the pres- sure of the fluid of the body cavity the largest portion of the segmental pouch is everted outward, while a small portion, fixed by the internal duct, remains into the body cavity. A muscular fascicle , which I believe could be ob- served sometimes , may have the function to withdraw the pouch and bring her back in the previous situation. Of course it remains somewhat questionable , whether the ex- truding of the pouches is a normal habit of the living animal , or whether it may be caused by the heavy con- traction of the body , as it Avas plunged in the alcohol. However the last supposition seems not very probable to me , because in that case undoubtedly tearing of the inter- nal parts should have taken place , which I could not ob- serve. Moreover it may be remembered that this is not the only example of extrudible pouches observed in Anne- lids, for Ehlers found in the feet of several G lycer a-s-pecies Notes from the Leyden Museum, "Vol. XI. 14 ON A REMARKABLE SVLL1S-BUD. bladder-shaped bodies , capable of being extruded , which he believes to be respiratory organs *). The eyes (fig. 9) of our worm , though not so highly developed as those of the Alciopidae , however seem to have a more differentiated structure as the large eyes of Genetyllis oculata described by Mac Intosh 2). There is no lens , but the total eye-cavity is occupied by a vitreous body , composed of exquisitely delicate fibrils , which era- diate from the fundus of the eye to the corneal surface. Immediately within the vitreous, and not always distinctly separated from it , is a layer of short fibres , thicker as those of the vitreous and darker stained , which undoub- tedly corresponds to the rod-layer of the retina in the eye of the Alciopidae. Outside of the rod-layer we have a layer of orange-coloured pigment, resting on the outer layer of the retina, which contains numerous nuclei, while the cells are not well-defined. Concerning the systematical position of these Syllis-sipe- cimens , there can be no doubt that they are originated by budding; this may be concluded from the presence of bristles in the first segment of the body , from the total absence of tentacular processes on the head , from the struc- ture of the alimentary tract, having no proper pharynx and proventriculus. This may also be presumed from the extraordinary development of the segmental organs, for we know from Ehlers' researches , that in the posterior segments of the body of the Syllidae , which contain the generative products , the segmental organs become much enlarged 3). Albert mentions also about the segmental organs of the swimming bud of Haplosyllis spongicola Gr. , that their middle region acquires a glandular appearance and much 1) Die Borstenwiirmer, p. 659 and 676. 2) Challenger Keport, Zoology, Vol. XII, p. 170, pi.

Segmental organs coloured by a dark pigment seem to have been observed also by Grube in Odontosyllis hyalina 2), a worm which probably also must be considered as a bud ; here he found in the posterior region of the body , situa- ted on each side of the nerve-cord, black coiled tubes, opening on the ventral side. However by the shape of its bristles, and its smooth dorsal cirri, this species is quite different from our specimens. J) Mittheil. aus der Zool. Station zu Neapel , Bd.

NOTE V. ON FILARIA-SPECIMENS FROM THE RIGHT VENTRICLE OF THE HEART OF FELIS ONCA. BY Dr. R. HORST. Some time ago Mr. J. H. Spitzly kindly forwarded to our Museum a few bottles with parasitic worms , collected by him in Surinam. Among them there was a bottle, containing some Nematodes found in the heart of a young female Jaguar, that was killed by a hunter. In reference to these parasites Mr. Spitzly wrote to me : » on incising the remar- kably thin walls of the right ventricle, I was astonished to find the whole cavity fully packed with long white worms, laying in bundles more or less parallel to each other in the direction of heart's apex to endings of pul- monary arteries. By slitting open the pulmonary arteries I found that some of them extended from the heart along the arteries far into the substance of the lungs." These worms bear a great resemblance to Filaria inmi- tis Leidy, observed by several investigators in the right ventricle and the pulmonary arteries of our common dog. Having no individuals of this species at my disposal , the specimens could only be identified from the short descrip- tion, published by Schneider in his » Monographic der Nematoden" pag. 87 ') ; therefore the Jaguar-filaria's af- terwards perhaps may prove to belong to another species. However because Nematodes never have been mentioned from the heart of Felis onca , as far I am aware off, I thought it not without interest to call the attention of helminthologists on this fact. 1) I much regret that I had no opportunity of consulting Welch's descrip- tion of the thread-worm , in the Monthly Microscopical Journal , Vol. X. .Notes from tlie Leyclen Museum, Vol. XI. ON MAMMALS FROM EAST-SUMATRA. 17 NOTE VI. ON A COLLECTION OF MAMMALS FROM EAST-SUMATRA. Dr. P. A. JENTINK. November 1888. Dr. B. Hagen , the well known passionate naturalist , lived several years in Tandjong-Morawa , later in Medau East-Sumatra, Deli. He published in »DasAusland, 1881" a paper, entitled »Vorlaufige Mitteilungen fiber die Fauna Ost Suraatras." In this paper he solely treated the Mam- mals , especially based upon the collections made by him- self and by his hunters. Afterwards he presented his whole immense collection to the Leyden Museum , several thou- sands specimens of Mammals, Birds, Reptiles and Insects. Up to the investigations made by Dr. Hagen about no- thing was known concerning the Mammals of the eastern part of Sumatra , and so I think that a review of his col- lections will be very wellcome to naturalists, the more as the Fauna of Sumatra is one of the bases upon which Wallace built his wide-stretching speculations. Wallace (the Malay Archipelago, 1869) made inquiries about the Orang-ütan (not Orang-Outang as Blanford writes , see the Fauna of British India , a. s. o. , Mamma- lia, Part I, 1888, p. 4), but none of the natives had ever heard of such an animal , nor could he find any of the Dutch officials who knew anything about it. He con- cluded therefore , that it does not inhabit the great forest plains in the East of Sumatra, but is probably confined to a limited region in the north-west. Von Rosenberg (Der Malayische Archipel, 1878) related: »der Orang- Notes from the Leyden Museum, Vol. XI. 18 ON MAMMALS FROM EAST-SUMATRA. Utan wird nur in den flachen, sunipfigen Küstenwald ern angetroffen , welche nördlich von Tapanoli das Land bis Singkel überziehen und ihrer Unzuganglichkeit wegen nur selten von einem nienschlichen Fusse betreten werden." Some years ago there was living in the Rotterdam -Zoolo- gical Gardens an Orang-Utan from the interior of Padang, West-Sumatra. In 1875 my brother-in-law hunted in Lang- kat, Deli, East-Sumatra, a very stout Orang-Utan, but unhappily the chinese-workmen had cut it to pieces be- fore he could prevent it. Dr. Hagen wrote in Das Ausland: »Unter den Affen mussen wir billigerweise zuerst erwahnen den Orang-Utan. Jeder Malaye hier auf der Ostküste kennt seinen Namen, Mawas oder Mauas , aber Alle stimmen ebenso darin (ther- ein , dass er auf der Ostküste nur etwa noch in der Provinz Oberlankat gegen Atjeh hiu vorkomme. Vor einigeu Tagen noch besuchte mich ein Malaye , der bei seinen Wanderun- gen in den naheliegenden Bergen , etwa vier Tagereisen von Tandjong-Morawa , ein Mawas-paar in einer tiefen Waldschlucht entdeckte, und sich anheischig machte, eines der Thiere zu erlegen. Einer meiner Diener, ein gesetz- ter , glaubwiirdiger Malaye aus der Gegend von Kap Tamian , erzahlte mir, vor mehreren Jahren habe ein grosser Mawas aus seinem Kampong ein kleines Kind ergriffen , mit sei- nen Armen erdrückt und bei der sofort augestellten Verfol- gung sich mit der Leiche auf einen nahen , nicht beson- ders hohen Bauru geflüchtet, allwo er von den wütend nachsetzenden Malayen, worunter auch mein Gewahrsmann sich befand , mit Spiessen und spitzen Bambus erstochen wurde. Das der Orang-Utan früher auf der Ostküste viel haufiger vorkam , ist für mich schon wegen der allgemei- neu Kenntniss seines Namens ausser allem Zweifel ; von dem Schrabrakentapir z. B. , der auch nur sehr lokal vor- kommt, hat keiu Eingeborner hiesiger Gegend eine Ahnung." Prom the foregoing facts we are allowed to conclude, that the Orang-Utan is to be found along the coasts of the northern half of East- and West-Sumatra. J^otes from the Leyden Museum, "Vol. XI. ON MAMMALS FROM EAST-SUMATRA. 49 In Dr. Hagen's collections are several Mammals hitherto not recorded from Sumatra , but known from Borneo , f. i. Arctogale stigmatica , Hemigalea derbyana , Herpestes bra- chyurus , Cynogale bennettii , Ptilocercus lowii and Rhizo- mys dekan. Leaving the bats out of consideration we see that the more our knowledge increases the more the uniformity of the Borneo- and Sumatra-fauna comes to light, but at the same time it appears that the Mammalian Fauna of East- Sumatra agrees much more with the Borneo- than with the West-Sumatra Fauna. West-Sumatra has several spe- cies hitherto not found in East-Sumatra and Borneo, so Borneo has several species not recorded from West-Suma- tra, but with two or three insignificant exceptions East- Sumatra has all its Mammals in common with Borneo, meanwhile none of the above named characteristic species in Hagen's collection from Deli has been found in the tolerably well known Western half of Sumatra. Dr. Hagen observed in Deli, besides the species enumerated below and the above mentioned Simia satyrus , the following species : Felis tig ris , n. i. Rimau or Harimau\ Felis pardus, var. melas , n. i. Rimau kombang; Ursus malayanus , n. i. Bruang ° Sorex sp. ? aud Mus sp. ? n. i. Tikus. With five exceptions all the Mammals, collected by Dr. Hagen, are from Deli, Serdang, Tandjong-Morawa; one is from the Toba-plains, and four are from Bengkalis and Siak, the two latter lo- calities opposite Singapore. Simiae* 1. Hylobates syndactylus Cuvier. Tandjong-Morawa, Marolam and Bander Labuan. n. i. Imbau, rarely Siamang. Hab. Sumatra and perhaps nowhere else, as the locali- ties, Southern Tenasserim and Malayan Peninsula, given by Heifer and Wallace are very doubtful. Notes from the Leydeia Museum, Vol. XI. 20 ON MAMMALS FROM EAST-SUMATRA. 2. Semnopithecus alb o ciner eus Schinz. Dr. Hagen (Das Ausland, 1881, p. 554) wrote: »zwei blaugraue Semnopitheci mit langen Schwanzchen und weisser Brust und Bauch. Der eine, von den Eingebornen Lutong genannt, ist sehr haufig, der andere, mit fieischfarbenen Gesicbt, dessen obere Halfte schmutzig ultramarin blau ist , mit samtschwarzen Hand- und Fuss-tellern , ist eben- falls nicht selten , aber sehr scheu und verborgen. Sein Jugendkleid ist goldgelb. Er heisst bei den Malayen Gjak- gjak wegen seines Geschreis, das, langsaui beginnend, all- mahlich schueller wird; es ist ein lautes , helles, gellendes Gjak-gjak-gjak-gjakjakjakjak. Morgens und gegen Abend hörtt man dasselbe am haufigsten." In Dr. Hagen's collections from Tandjong-Morawa are four skulls labeled Lutong, and three labeled Gjak-gjak. The Lutong-skuWs agree with the skulls of Semnopithecus albocinereus in our Museum, a monkey with white breast and belly and known from Malacca and East-Sumatra. Prof. Schlegel (Simiae, 1876, p. 39) observed: »le sque- lette du S. albocinereus diffère de celui du S. mitratus en ce qu'il offre une paire de cötes de plus, savoir treize paires", but here he was not correct, for one of the ske- letons (Schlegel, N°. 9) has 13 pairs of ribbs and the other (Schlegel, N°. 10) presents 12 pairs and no trace of a 13th pair. So that in this, like in the next species, the number of ribbs is very variable. The skulls ƒ, g and h (Jeutink, Catalogue Ostéologique , 1887, p. 10) belong to S. albocinereus and not to S. fer- rugineus. 3. Semnopithecus melalophus Raffles. Tandjong-Morawa.. Prof. Schlegel (Simiae, 1876, p. 42) separated under the name Semnopithecus ferrugineus the Monkeys from Pa- dang from their congeners living in the neighborhood of Notes from tho Loydon. ^Museum , Vol. .X I ON MAMMALS FROM EAST-SUMATRA. 21 Bencoelen and Indrapore, and distinguished exteriorly by a slight difference in tinge, but according to Schlegel S. ferrugineus has 13 pairs of ribbs, meanwhile S. mela- lophits presents 12 pairs. Our Museum procured from the Dutch Scientific Expe- dition to Sumatra skins and skeletons of a Monkey , from the interior of Padang , belonging to S. melalophus. The skeletons (Jentink, Catalogue Ostéologicpue , 1887, p. 10) however present the following numbers of ribbs : sk. b has 13 ribbs to the left side and 12 to the right side, sk. c has 12 to the left and 13 to the right, sks. d and e present 12 ribbs to the right and 12 to the left. More- over in sk. c of the so called S. ferrugineus I find 13 ribbs to the right and 12 to the left, and not 13 pairs of ribbs as Schlegel stated in his Catalogue. There is thus no reason to accept Schlegel 's new species , as the number of ribbs , being preponderant in Schlegel's opinion , is so very inconstant. The young of Hagen's Monkey being golden-yellow and the skulls of the adult specimens agreeing very well with the skulls in our collection, I refer these individuals to the above named species, so that S. melalophus now is known from the Malayan Peninsula and from East- and West-Sumatra. 4.

Although I caunot accept with Schlegel a separation of the Java-specimens under the name of Nycticebus javanicus Geoffroy, as I find no difference whatever in the skulls or other bony parts and as the supposed difference in color is merely a difference in tinge, it however is a fact, that, at least in our skeletons — two of N. tardigradus and five of N. javanicus — the number of dorsales and lumbares is 24 in the Java-specimens, meanwhile it is 22 in the true N. tardigradus (Schlegel, Monographic, Simiae). 7.

As I remarked in the Notes from the Leyden Museum , 1885, p. 34, this species was formerly only known from Borneo. 14. Hemigalea der b y an a Gray. Tandjong-Morawa. Gray described in 1837 an animal from an unknown locality under the name of Paradoxurus derbyanus and an- other new species , Paradoxurus ? zebra , from a drawing-. In the » Verhandelingen , 1839 — 1844", an animal has been figured which had been described in 1838 by S. Muller as Viverra boiei from Borneo. Later on (P. Z. S. L. 1864) Gray united his two new species with Mfiller's species under the name of Hemigalea hardwickii: under that title, Viverra hardwickii, Gray had described a drawing said to have been made after an animal from Malacca, found in the collection of Major Farquhar, cf. Spie. zool. 1830. In our Museum are specimens from the two certain localities , Sumatra and Borneo. 15. Herpestes brachyurus Gray. The Musang turon, as this species is called on the Ma- layan Peninsula, seems to be a very rare animal in the countries where it lives , or very difficult to procure , as only the following few specimens have been recorded. The type-specimen is in the British Museum and descri- bed hy Gray in 1837 as inhabiting Indian islands. Cantor, 1846, recorded this species in his Catalogue from the Ma- Notes from the f-.eyden Museum, Vol. XI. 24 ON MAMMALS FROM EAST-SUMATRA. layan Peninsula. Another specimen , figured by Gray in 1849, was one of the scientific results of the Voyage of the Samarang; it had been collected in Borneo. The lower jaw of a skull of another specimen has been figured by de Blainville in his Ostéographie , but he did not mention the origin. I have a third locality to add to the two hitherto known ones , viz. : Siak , as Dr. Hagen presented to the Museum a beautiful adult female with its skull from that locality. Length of the skull 91 mm., width at zygomatic arches 52 mm. ; also about the dimensions given by Gray in his Catalogue of Carnivorous a. s. o. Mammalia, 1869, p. 154. 16. C 'y no gale bennettii Gray. Gray described this species after a specimen in the Bri- tish Museum from Sumatra, as he wrote in 1837; it seems however that the named locality was incorrect , for in the Catalogue of the Bones of Mammalia, 1862, the skull, belonging to a specimen of this species in the British Museum had Borneo for locality , agreeing with the habi- tat given by Gray for the specimen in the Catalogue of Carnivorous a. s. o. Mammalia, 1869. In the » Verhan- delingen, etc." has been described and figured another specimen , under the name of Potamophilus barbatus , too from Borneo. So that up to the year 1882 Borneo was the certain patria. In 1882 however Dr. Hagen procured a young specimen from Tandjong-Morawa , Deli. Its skull is in our Museum. 17. P ut o r iu s nu dip e s Cuvier. Specimens from Tandjong-Morawa. It is not very clear why Dr. Gray changed Cuvier's specific title and called the species Gi/mnopus leucocephalus , see P. Z. S.

There are in our Museum specimens from Sumatra, Ma- lacca, Borneo and Java. Besides skulls , unmistakebly belonging to this species , there is in Dr. Hagen's collection a skin , without skull , which I refer with some doubt to this species. It is appa- rently a young individual , as the feet are too large in pro- portion to the rest of the animal. Head , upperparts , tail and feet are black with a reddish tinge , underparts brown- ish red. As there is only a single species of Pteromys known as inhabiting Sumatra , viz. : Pteromys nitidus , and as Dr. Hagen collected this species too in Tandjong-Morawa, so I regard his young specimen as representing a black variety of Pteromys nitidus Geoffroy. Length of head and body 280 mm., length of tail with tuft 440 mm., length of hind foot with claws 57 mm. 27. Sciuropterus h a g e ni n. sp. Deli.

The latter is from the Mainland of Borneo , opposite to Labuan and figured on Plate XXXVI. I find in Dr. Hagen's collection a specimen of T. ferruginea with a golden yellow tail , with a reddish tinge , like Dr. Giin- ther's variety of T. tana. If naturalists think it necessary to give a name to every variety of a given species , what is impracticable in my view, the mentioned specimen may be entitled Tupaja ferruginea , var. chrysura. 40.

H el o g al e p a r v u l a Sundevall. Dr. Gray created in 1861 (P. Z. S. L. p. 308) the genus Helogale and thus separated three small species of African Mungooses with the dental formula I. J , C. 1, P. M. |, M. | = 36 , from the other true Herpestidae. The three species are: Herpestes parvulus Sundevall (1846), collect- ed by Wahlberg in the neighborhood of Natal , Herpes- tes undulatus Peters (1852) from Mossambique, and Ich- neumon taenionotus Smith (1835) from S. Africa (Natal apud Gray). A skull (P. Z. S. L. 1861, p. 308), belong- ing to a skeleton (Catalogue of the bones, 1862, p. 76) of one of Smith's types, was in the British Museum, but it seems that the skeleton has been lost , for in P. Z. S. L. , 1 864:, p. 565, Gray states that in the British Museum is a skull only ; meanwhile the teeth had increased in num- ber, from 36 (in 1861) to 40 (in 1864)! Now Gray thought it correct to give another genus-name to that highly in- teresting skull and called it Ariela taenionota and under the very name he cited it in the Catalogue of the Carni- vorous a. s. o. Mammalia, 1869, p. 163. Later on the number of teeth again decreased from 40 (in 1869) to 36 (in 1882) and finally Oldfield Thomas (on the African Mungooses, P. Z. S. L. 1882, p. 90) placed it under the synonyma of Crossarchus fasciatus Desmarest, where I hope that it will be buried for ever. Notes from the Leyden Museum , Vol, XI. 32 HELOGALE PARVULA. As Oldtield Thomas observed ia the above named ex- cellent monograph , there are in most of the larger Euro- pean Museums typical specimens of Sundevall's Herpestes parvidus; so we possess too one of these type-specimens with its skull. In comparing this skull with the figure of the skull of Helogale parvula on p. 308 (P. Z. S. L. 1861) or with that given by Peters on pi. XXV (Reise nach Mossambique) of Herpestes undulatus , I find no difference at all. Oldfield Thomas wrote (I.e., 1882) that in H. parvula the skull is larger and the last molar smaller in proportion , but Thomas gives the length of a skull of H. parvula = 1.82 inches, meanwhile Peters said that the skulls of the types of undulatus measure 48 and 46 niM. , or 1.9 and 1.82 inches (the Taita-skull, see Thomas, seems to be '/io of an inch larger) , so that I state that there is no difference in length between the skull of H. parvula in the British Museum (and I may add also in the Leyden Museum , as our skull measures too 1.82 inches) and that of one of the types of H. undulata in the Berlin Museum ; the other in the Berlin Museum being somewhat larger and the Taita-specimen in the British Museum is a still larger spe- cimen. The difference in size between the last molars of the two supposed species is too small to take in conside- ration (H. parvula , a has M2 = 4.0, b has M2 = 4. 1 , and H. undulata , a has M2 = 4.0, cf. Thomas , P. Z. S. L. , 1882, p. 80). According to Gray, Peters and Thomas there is however a difference in color between H parvula and H. undulata , but I remember that it is a well known fact that there is often an enormous variation in color in the different specimens of a given species belonging to the Herpestes- group (see Temminck and Oldfield Thomas) , so that color alone is in this case a character of second order in distin- guishing species. In my opinion therefore there is known only a single species of Helogale , //. parvula Sundevall ; this opinion is Notes from the Leyden Museum , A^ol. X.I. HELOGA.LE PARVULA. 33 supported by two specimens , belonging to a Helogale- species, received the other day from Gambo or Gambos (in- terior of Mossamedes) by Mr. v. d. Keilen. One of these specimens, the skin and skeleton of an adult male, has the skull exactly agreeing in size and shape with the skull of Sundevall's type-specimen in our Museum , but the color of the fur is less dark , more red- dish-yellow, than in Sundevall's: the other, a much young- er individual with a not yet fully developed dentition , has the fur darker tinged than v. d. Kellen's adult one, somewhat intermediate between the latter and Sundevall's. The skeleton presents 7 cervicales, 13 costales , 7 lumba- res , 3 sacrales and 28 caudales ; that are the same num- bers as Peters found in the skeleton of his Herpestes un- dulatus, the only difference being 3 caudales less in Peters' specimen. The habitat of Helogale parvula is perhaps the whole Southern part of Africa, as we know it from Mossambique , Natal and the interior of Mossamedes.

Amongst the last birds received from Mr. Stampfli , there was a very peculiar new Owl, which I propose to name Bubo lettii, after its discoverer Mr. Lett, our former landlord and huntsman at Schieffelinsville. This Owl shows no affinity to any of the Owls at present known from the old world, but might rather be compared with the West-Indian Bubo crista- tus, on account of the exceedingly long ear-tufts aud the white alar spots. General color rufous, forehead, superciliary streak, chin and upper throat pearly gray, slightly vermiculated with earthy brown, which latter color predominates on occiput, hind neck and ear-tufts. Eye-lashes and feathers in front of the eye black, cheeks aud ear-coverts rufous, with darker vermiculations. Si- des of throat white, each feather broadly tipped with black. Mantle, back, rump and upper tail-coverts uniform rufous, tail rufous, with seven broad black bars. Wings rufous, the quills and wing-coverts broadly barred with black. Four of the median wing-coverts have a large white oval spot on the outer web near the tip. Lesser wing-coverts and primary coverts almost black, tipped with rusty brown; scapulars ru- fous, strongly vermiculated with pearly and dark brown, the outer ones white on the outer web, with a broad black termi- nal edge, forming together a conspicuous longitudinal white row.

CONTRIBUTIONS TOWARDS THE KNOWLEDGE OF THE ANNELIDA POLYCHAETA. Dr. R. HORST. On Arenicola-sipecimens from the Gulf of Naples. (Plate 3). Some time ago a finely preserved collection of Anne- lids was procured by our Museum from the Zoological Station at Naples ; among them I observed some specimens of Arenicola, which in their characters do not agree with the species , hitherto known from the European coast. Going over the litterature about this genus, I saw that not only there reigns a good deal of confusion in the de- scription of the different species , but that we want even an accurate knowledge of the feature of the bristles and branchiae of our European species. Almost all the authors have given an erroneous account of the appearance of the branchiae of the common A. marina] nevertheless Wil- liams2) in the year 1851 already stated: »they are com- monly described as forming an arborescent tuft; the division of the vessels is however regulated by a fixed prin- ciple. When fully injected with blood , the vessels of each branchia form a single plane etc." Even a superficial examination is able to convince us of the correctness of Williams' assertion, though his drawing is not very accu- 1) For Part I see Vol. VIII, p. 157. 2) On the British Annelida; Report of the British Association for 1851, p. 195, pi. 4, fig. 13.

Indeed each branchia of the common lug-worm con- sists of about 12 secundary branchiae, connected by a membrane at their base and situated next to each other in the same plane, like the divisions of a palmated leaf; these secondary branchiae are not irregularly branched , but possess a middle axis , furnished on each side with 3 or 4 tufts of filaments (fig. 2). If the number of those lateral tufts much increases , as is to be observed in some species of Arenicola, and the middle axis bears on each side, in stead of 4 , 12 or more racemous tufts, the secondary branchiae resemble a feather (fig. 6). Therefore a South-American species , provided with such plumous branchiae , was named by Liitken Pteroscolex, which he wishes to be considered as a sub-genus of Arenicola *). However if we would retain this name, as proposed by Levinsen2), then also our A. marina ought to be ranged in that sub-genus , because there is only a gradual difference between the branchiae of A. antillensis and marina. Claparède seems not to have rightly understood Lütken's description ; otherwise he would not have written 3): »toutes les branchies sont disposées dans un même plan, comme les nervures d'une feuille, et ne forment pas de buisson touffu. Ce caractère a été relevé chez une Arénicole des Antilles par M. Lütken etc." Branchiae, which are really arborescent, are to be met with in A. Grubii (fig. 12), probably also in A. branchia- lis , Boeckii a. o. • in those species the branchiae are bran- ching directly at their base, and no real secundary bran- chiae or branchial leafs are formed.

ANNELIDA PÜLYCHAETA. 39 In the Gulf of Naples a species of Arenicola is to be found , which in the number of its setigerous and bran- chiferous segments agrees with our northern A. marina , but in its other characters shows too much differences, to be identified with this species. Claparède seems to have already presumed this, for he writes: »une étude comparée plus approfondie ne révélera- t-elle pas des differences spécifiques entre les individus de la mer du Nord ou de l'Océan et ceux de la Méditerranée?" However Levinsen has been the first, who considered the Mediterranean specimens to be specifically different from the northern form and named it A. Claparedi; he also pointed out some characters by which this species is di- stinguished from A. marina. The only specimen I could examine has a length of 75 m.m., the caudal region measuring 6 ni.m.; on the contrary our A. marina attains sometimes a length of 250 m.m. This agrees with Claparède's statement: »mais ce sont de véritables pygmées relativement aux Arénicoles du Nord. La longueur moyenne des adultes mürs est de six a sept centimetres." A. Claparedi resembles A. marina in the presence of 19 setigerous segments, of which only the posterior 13 are provided with branchiae; I do not understand how Levinsen can write about this species : »gjaeller findes paa 12 — 13 riuge", for all naturalists, who examined this worm , agree with each other in this point. It is true, Pennant1) as well as Dalyell 2) have figured A. marina only with 12 pairs of branchiae, but we have no doubt that the drawer has overlooked the first pair of branchiae on the 7th segment, which is much smaller than the others ; for we read in DalyelPs descrip- tion p. 136: » thirteen pair of beautiful vermilion branchiae rise from the back." 1) British Zoology; copied in the Encyclopédie méthodique, Vers, pi. 34, ;. 16. 2) The powers of the Creator, Vol. II. pi. XTX, fig. 1. Notes from the Leyden Museum, Vol. XI. 40 ANNELIDA POLYCHAETA. In A. Claparedi the branchiae are generally more deve- loped as in A. marina, and the first pair of them, though not so large as those of the middle body-segments, are rather large. The branchiae consist of about 18 branchial leafs, situated in the same plane, and connected at their base by a common membrane; each branchial leaf bears on its sides about six branched filaments , of which the inferior are somewhat longer than those at the tip. The ventral bristles (fig. 1) can easely be distinguished from those of A. marina ; they are characterized by an obvious en- largement , serrated at its convex side beneath the hook- like curved tip (fig. la). In A. marina the ventral brist- les are not quite smooth as commonly described by the authors , but they show at the convex side one or more faint serrations (figs. 3 and 4). The dorsal bristles resem- ble those of A. marina, which have been accurately descri- bed and figured by Grube. Their distal portion is furnished along one side of the shaft with numerous short hairs, giving it a finely serrated appearance, whereas the other side is provided with a narrow membrane. Probably this membrane is composed of hairs , lying densely near each other , for examined with a high power it shows faint, transverse lines and a serrulated edge (fig. 5). Levinsen gives the following characteristics of A. Cla- paredi: » branchiae, which are connected at their base only by a very short membrane, stretched, with 10 pair of branches; dorsal bristles with very faintly developed hairs, ventral bristles with more acutely pointed , somewhat se- parated tip. The branchiae , as stated afterward , agreeing in their structure with those of Pteroseolex antillensü, above referred to." Though this description does not quite agree with my own observations, nevertheless I hesitated to pro- pose another name. Perhaps he confounded with A. Cla- paredi individuals of the following species, which possesses branchiae , agreeing in structure with those of A. antillensis. A. cristutu Stimpson (figs. 6 — 11). — Proceed. Boston Notes from tb.e Leyden M useum , Vol. XI. ANNELIDA POLYCHAETA. 41 Society of Nat. History, Vol. V, 1856, p. 114; A. antil- lensis Lütken. loc. cit. Among the Arenicola-STpecimens of Naples there are two individuals , agreeing with A. marina in feature and size of the body , but plainly distinguished from it by several characters. The number of setigerous segments is only 17, of which the posterior 11 are provided with branchiae. The first branchiae, situated on the 7th segment, as in A. marina , are less developed than the following. The branchiae consist of about 12 branchial leafs, situated next to each other in the same plane , but scarcely connected by a membrane at their base ; each branchial leaf has a long middle axis and a great number (to 20) of short, branched filaments on each side, resembling a feather. The bristles of the dorsal fascicles have about the same length as those of A. marina , but they are more nume- rous and darker coloured; they are arranged in two dis- tinct transverse rows , the bristles of the posterior row being twice as long as those of the anterior one. The brist- les are more hairy as those of A. marina ; the transver- sely striated membrane along the distal portion of the bristles in this species , is substituted here by a broad row of distinct hairs , and also along the other side of the bristle short hairs are to be found (fig. 9). The anterior two setigerous segments seem to want the ventral fasci- cles, at least they are not visible externally. The ventral bristles are slender , with a more or less curved tip ; at a short distance beneath the tip they are a little enlarged and furnished at the convex side with a great number of faint serrations (figs. 7 and 8). The proboscis is covered over its whole surface with large rounded , triangular papillae. Length of the largest specimen 230 m.m. ; length of its caudal region 85 m.m. A. cristata , described by Stimpson from the shore of Maurice-Island (South Carolina), seems to agree in its main . characters with our specimens ; therefore , though Stimpson Notes from the Leyclen Museum, Vol. XI. 42 ANNELIDA POLYCHAETA. gives no figures or detailed descriptions of bristles or bran- chiae , I believe our specimens are referable to this species. It seems to me very probable that A. antillensis , accurately described by Lütken, may be identical with A. cristata] that the former species has a wider geographical distribu- tion is already stated by Ehlers (Florida-Annelida, p. 173) who mentions it from the coast of Florida. Lütken seems not to have known Stimpson's description, at least he does not mention it His A. antillensis is characterized in the follo- wing manner: »anuulis setigeris 17, anterioribus 6 ebran- chiis , ceteris branchiferis , branchiis e foliis plumiformibus c. 15 compositis, fasciculis filorum respiratoriorum ad latera trunci mediaui collocatis plumassingulas formantibus; annu- lis caudalibus 8 nudis (sine setis et branchiis), papilliferis. Longitudo usque ad 0.35 M. Hab. ad oras Ins. An- tillarum." There is only one character in Liitken's description, that is open to doubt; this is the presence of long, projec- ting papillae at the ventral side of the caudal region , which are identified by Levinsen with branchial filaments. Ehlers, however, makes no mention of those papillae. Two other small specimens of Arenicola are to be men- tioned , which agree with this species in the number of setigerous and branchiferous segments, but which present some other different characters ; therefore I am somewhat dubious if they should be considered either as immature specimens of A. cristata or as another species The largest specimen has only a length of 60 m.m. , its caudal region measuring about 12 m.m. The branchiae consist of 10 to 12 branchial leafs, not connected at their base; they are not so slender as those of the larger foregoiug specimens, their inferior filaments being more branched and longer as those of the tip. The dorsal bristles are not so hairy and resemble those of A. marina (fig. 11). The proboscis is densely covered with acute, conical papillae; only at the base there is a region of about 5 series of obtuse trian- gular papillae. Notes from the Leyden Museum , Vol. XI. ANNELIDA POLYCHAETA. 43 Avenicola Grubii Clprd. (figs. 12—15). — Clapa- rède, loc. cit. p. 36, pi. XIX, fig. 2J5, 27. This species seems to be very common in the Gulf of Na- ples, for among thirty ^4reraVo/a-specimens from this locality , which I could examine, twenty-five belonged to A. Grubii1). Grube first met with those worms at the shore of Catania; therefore Claparède , who found them afterward at Naples, named the species in honour of that distinguished investi- gator of Annelids A. Grubii. It is to regret that a sin- gular mistake seems to have crept into Claparède's descrip- tion, for we read there: »segmeutis anticis branchiis destitutis decern" and afterward »dans l'espèce napoli- taine, la première paire de branchies est toujours au dixiè me sétigère" 2); however those numbers are quite at variance with the description of Grube, who writes: »ich zalilte 38 paar Borstenbündel , von denen die ersten 11 isolirt, die übrigen 27 mit Kiemen zusammenstanden.' The exactness of Grube's statement could be confirmed by me, for I found the first pair of branchiae without any exception situated behind the 12th dorsal bristle-fascicle. The largest specimen has 38 setigerous segments. The first pair of branchiae is not smaller as those of the following segments ; however in the posterior region of the body the branchiae gradually decrease in size, and the posterior segments want them totally , or they are only represented by a small filament with a couple of short branches. The branchiae do not consist of secundary branchial leafs, but are arborescent, branching directly at their base; they show 3 or 4 main stems, which divide dichotomously and terminate in numerous filaments. The dorsal fascicles con- 1) By the liberality of Prof. Hubrecht the Arenicola-syetivaens of the Utrecht Mu9eum were also placed in my hands for examination. 2) This erroneous description is repeated in Cams'' Prodromus Faunae medi- terraneae ; it is an example to illustrate the dubious valour of such a catalo- gue drawn up without any critic ; had the author could limit himself to a simple enumeration of the species and the litterature , his work should have been less painful for himself, and as useful for the public. Notes from the Ley tien Museum, Vol. XI. 44 ANNELIDA POLYCHAETA. sist only of a small number of bristles ; those are rather smooth, a narrow membrane along their distal portion is scarcely visible and the tip is covered with some scaly hairs. The ventral bristles resemble somewhat those of A. marina, but they are furnished at the convex side of the hook-shaped tip with a secundary tooth , behind which some faint serrations are visible (fig. 13); Claparède has recogni- zed this character, but his figure is not very correct. In this species the ventral bristle-fascicles of the anterior body- region are not much smaller as those of the posterior brauchiferous region , like in the foregoing species , but they have about the same dimension , and reach nearly to the median ventral line; whereas f. i. in A. marina the 5th ventral fascicle contains about 20 bristles , in this species the number of them will amount to about 100. The proboscis is covered with acute conical papillae; only at its base there are about 5 series of large and more obtuse ones. From Prof. Oliveira of Coimbra I received for identifi- cation an ^fmnVo^a-specinien from la Granja (Coast of Portugal); this specimen agrees in many regards with A. Grubii, therefore I am not inclined to base a new species upon it. The worm has a length of 105 m.m. , but it wants a portion of the posterior region. There are 34 se- tigerous segments. The branchiae agree in their feature with those of A. Grubii ; the first pair of them is also situated on the 12th setigerous segment, but is not so developed as in the last species. The bristles show some small differences; the dorsal bristles have an obvious mem- brane along their distal portion (fig. 15) and the ventral ones have only a single tooth without serrations behind (fig. 14). Perhaps it may be considered as a local variety of A. Grubii. Notes from the Leyden Museum, Vol. XI. ANNELIDA POLYCHAETA. 45 EXPLANATION OF Plate 3. Fig. 1.

Dès 1876, j'avais décrit YHister Leseleuci sur un exem- plaire du Grand-Bassam , mais la description était restée dans mes cartons, lorsque Mr. Ritsema m'envoya en com- munication 12 exemplaires provenant de Liberia et 5 de Humpata, que je crus devoir y rapporter, les premiers parti- culièrement, malgré quelques légères differences. Mr. Schmidt pretend que les exemplaires de Humpata appartiennent a une espèce différente de ceux de Liberia, qu'ils sont iden- tiques a son Mechowi, et de plus que Ie Leseleuci n'est qu'un synonyme du tropicalis. Je ne connais Ie Mechoici que par la description publiée dans Ie Berl. Ent. Zeits. (Vol. XXVII, p. 147), mais malgré les nouvelles explications de mon ardent émule en Histéro- graphie, cette description reste pour moi un énigme. En effet il rapproche son espèce de Yunicolor avec lequel elle n'a aucun rapport, et du tropicalis qui lui est inconnu puisqu'il n'a pas vu Ie type; au lieu d'etre légèrement arqué sur les cótés , celui-ci est dilaté-arrondi au milieu et par suite rétréci devant et derrière , et son pygidium n'est point couvert de points serres et presque rugueux , mais de points faibles et écartés. — Je veux bien en croire Mr. Schmidt sur son affirmation, mais je crains qu'elle ne soit hasardée, comme la plupart de ses synonymies récentes. Quant a V Hololepta sternincisa , ce n'est qu'avec beau- coup d'hésitations, que j'y ai rapporté comme variété les exemplaires amoindris , tout en les désignant sous Ie nota provisoire de parvifossa.

Macleay's »Annulosa javanica" (London , 1825) I was surprised to find in this work (p. 48) the description of a Chelonarium-sipecies. This description seems to be overlooked, as the species is not mentioned neither in the Munich Catalogue (vol. Ill, p. 930) nor by Reitter 1), Chevrolat 2) and Fleutiaux 3) who have described other Oriental species of this genus. I therefore believe it not without interest to give here Macleay's de- scription of the first known oriental representative of this interesting genus. » Genus Chelonarium , Fab. 94. Villosnm.

Q. A small species which is allied to Pachyteria parallela Rits. (Notes Leyd. Mus. 1881. p. 36). Length 19 mm.; breadth at the shoulders 5 rum. — The head, the prothorax and the scutellum bright metallic green; the smaller basal half of the elytra ochreous , with faint purplish tiuges , the greater apical half dark bluish green , brighter towards the apex, and provided just before its middle with a slightly waved, narrow, transverse, ochreous band which touches neither the sutural nor the outer mar- gins; the two basal joints and the basal third of the 3rd joint of the antennae black , the remaining joints ochreous ; the meso- and the metasternum as well as the legs and the abdomen violaceous blue, the latter tinted with green. The vertex of the head , a transverse band and a semi- circular spot on the pronotum , and the dark coloured part of the elytra densely covered with a very short black pubescence , which is however sparser on the apex of the elytra; the anterior tarsi brown and as well as the inside of the tibiae of the same pair of legs covered with a pale glittering pubescence. The undersurface of the body covered with a silvery pile forming bands across the hind margin of the four basal abdominal segments. The inter-autenuary ridge, which is divided by a deep Notes froiri the Leyden Museum, Vol. XI. 4 50 PACHYTERIA VANDEPOLLI. but very narrow groove, and the vertex of the head opa- que in consequence of a very dense though fine sculpture; the clypeus smooth and impunctate along the middle, pro- vided with large punctures at the sides; the mandibles on the outside and the space between the eyes and mandibles sparsely punctured ; the punctures beyond the eyes placed between longitudinal wrinkles: the undersurface of the head transversely wrinkled. The antennae rather short and thick, not quite reaching the narrow ochreous band in the dark coloured half of the elytra; the scape is short and thick, above rugose , beneath strongly punctured ; the 3rd joint equal in length to the 4th and 5th joints taken together, the 4th joint distinctly shorter than the 5th , the subse- quent joints slightly decreasing in length. The prothorax armed on each side behind the middle with a rounded tubercle which is separated from the disk by a narrow groove; the disk coarsely sculptured, the pu- bescent parts opaque ; the sides glossy , sparsely punctured ; beneath transversely wrinkled. The scutellum broadly trian- gular with curvilinear sides , densely and irregularly sculp- tured. The elytra parallel, conjointly rounded at the apex, and provided with three faint longitudinal costae ; the ochreous basal half densely and irregularly punctured , whereas the sculpture of the dark apical half is very fine and dense. The anterior and intermediate femora are covered with large and deep punctures , which are not densely set ; the posterior femora are very densely punctured on the out- side, much sparser on the inside; the sculpture on the tibiae is very fine and dense. The apical (5th) ventral segment is rounded at the tip and provided with a few punctures on the apical half. The described female specimen originates from Malacca and belongs to Dr. Baden's collection which is now in the possession of Mr. Neervoort van de Poll to whom I dedi- cate this pretty species.

Quant a la sculpture, je n'observe aucune difference : elle consiste en une reticulation d'uue extraordinaire finesse et tres peu imprimée dont les linéo- les extrêmement serrées et longitudinales s'anastomosent fréquemment; la couleur est la même, extrêmement bril- lante, noire sur les élytres, avec la tête et Ie pronotum plus ou moins rougeatres, les pattes, antennes et Ie des- sous du corps d'un ferrugineux plus ou moins foncé.

Je possède quelques exemplaires du Senegal , Cap Vert , que m'a donnés le Dr. Roussel et que je rapporte a cette espèce: ils sont un peu plus petits (4 — 41/2 mill.), peut- être un peu plus étroits et exactement semblables comme coloration. Deux d'entre eux constituent cependant une variété bien distincte: les ligues noires onduleuses sont brusquement interrompues en arrière du milieu en un espace de forme un peu arquée entièrement pale ; cette variété se rapproche beaucoup de la forme ordinaire du L. Sharpi Régb. (flexuosus + Sharp) dont elle se distingue néanmoins par sa forme moins dilatée aux épaules et par l'absence de l'interruption basale des lignes flexueuses.

Il est possible que ces lineaments varient d'un individu a l'autre, celui que j'ai sous les yeux étant unique. Humpata (van der Keilen). Laccophilus flavö-pictus, n. sp. Long. 33/4 mill. — Ovalis, sat latus, postice attenuatus , persubtilissime reticulatus ; subtus ferrugineus, pedibas antennis et capite fulvis; pronoto flavo , antice et postice late nigro ; elytris nigris , margine laterali ante medium , vitta transversa postbasali , regulari et suturam non attingente , maculis dua- bus ad latera , guttulaque ad apicem vix conspicua flavis. Cette jolie espèce rappelle par sa coloration Ie L. notatus Bohem. d'Amérique meridionale; mais sa forme est un peu plus allongée et surtout plus atténuée en arrière; la reti- culation est extrêmement fine et en outre se trouve enfer- mée dans une autre reticulation a mailles larges, forniée de lineaments extrêmement fins et peu imprimés.

Humpata (van der Keilen). Bien que ces deux dernières espèces ne me soient con- nues que par un seul exemplaire, elles m'ont paru si bien caractérisées , que j'ai cru devoir les décrire.

Cette espèce est absolument unique jusqu'ici par sa fbrrae oblongue , allongée, a cötés presque parallèles, brusque- ment arrondie en avant , non moins brusquement rétrécie et acuminée en arrière , peu convexe dans Ie sens longitu- dinal. Tout Ie dessus du corps est couvert d'une reticu- lation fine et peu imprimée.

HYDROVATUS PARALLELUS. 55 du bord externe. Les élytres présentent Ie ruême poiutillé obsolete et encore plus fin ; elles sont pourvues de trois séries longitudinales de points tres serres, dont l'externe est double, et de plus on remarque entre la série interne et la moyenne une rangée de gros points tres écartés. Les pattes antérieurs sont relativeinent robustes , cequi me ferait supposer que Ie seul exemplaire a ma disposition est un male, d'autant plus que les quatre tarses antérieurs sont larges et garnis en dessous d'une double rangée de cupules bien distinctes. Le dessous du corps et notamment les han- ches postérieures sont lisses avec quelques rares petits points. Humpata (van der Keilen). Derovatellus africanus, n. sp.

La trouvaille en Afrique d'un Derovatellus est un fait des plus interessants , car , a part le D. orienfalis Wke. , découvert dans ces dernières années a Borneo , le groupe des Vatellini était jusqu'alors exclusivement américain. Cette espèce est plus grande que les deux autres (D. lentus Wke. et orientalis Wke.); sa forme est longuement ovale, tres atténuée en avant et assez convexe, la couleur est presque mate , noire ou noiratre , avec le devant de la tête et les cötés du pronotum d'un roux ferrugineux, et quelquefois une petite tache ferrugineuse sur le cóté et en arrière du milieu de chaque élytre; le dessous est ferrugineux foncé, les épipleures et les quatre cuisses antérieures roux ; les pattes antérieures et iutermédiaires sont longues et leurs tarses dépassent en longueur les tibias ; chez le male les deux premiers articles sont sensiblement dilates. Tout le corps est couvert de gros points rugueux tres serres. Notes from the Leyden Museum , "Vol. XI. 56 DEROVATELLUS AFRICANUS. Humpata (van der Keilen). — Quelques exemplaires des deux sexes. Pachydrus coyennensis (Cast.?)

Tout Ie corps est couvert d'une ponc- tuation assez fine et raédiocrement serrée, mais bien im- prirnée, plus fine sur la tête dont Ie clypeus est arrondi, finernent rebordé et un peu relevé , et sur Ie pronotum dont la surface est un peu inégale; les élytres présentent sur Ie disque une série ponctuée tres peu visible. Cet in- secte se rapporte bien a la description d'Aubé; mais il est douteux , ainsi que Ie fait remarquer Ie Dr. Sharp, que ce soit Ie même insecte que celui de Castelnau dont la de- scription est d'une brièveté deplorable. Paramaribo (J. H. Spitzly). — Un exemplaire. Hyphydrus parvicollis Sharp, On aquat. earn.

Coloration d'un roux ferrugineux , avec Ie bord antérieur et la base du pronotum largement noirs au milieu ; élytres jaune fauve avec la suture et deux bandes noires, séparées en avant mais largement réunies en arrière oü la colora- tion noire envahit presque toute la surface, sauf Ie bord externe. La ponctuation est forte , serrée et reguliere sur les élytres , plus fine et moins dense sur Ie pronotum et la tête dont Ie clypeus est finement rebordé et a peine arrondi en son milieu.

Capite, cor- pore subtus , antennis pedibasque rufo-ferrugineis, pronoto nigro , ad latera ferrugineo; elytris nigris f ere sicut in Hy- groto inaequali Fab. testaceo variegatis. Espèce de forrae tres arrondie, distincte par la double ponctuatiou qui couvre les élytres : les gros poiuts sont réguliers eutre eux , tres imprimés et médiocrernent rap- prochés, les petits points également égaux entre eux sont plus denses et bieu moins imprimés; sur Ie pronotum les premiers n'occupent guère que Ie voisinage du sommet et de la base, tandis que les petits sont répandus partout; sur la tête la ponctuation est plus dense , bien imprimée , pres- que egale et intermediaire. Comme coloration il ressemble beaucoup a VU. impressus Klug (Coquereli Fairm.), de Madagascar, qui, comme lui, a la tête rousse, Ie prono- tum noiratre avec les cötés ferrugiueux et les élytres noi- res, variées de testacé roux avec une disposition analogue a celle qui existe chez V Hygrotus inaequalis Fab. — Les males ne différent des femelles que par uu peu plus de largeur dans les tarses, et encore ce caractère est-il trè subtil. Humpata (van der Keilen). — Quelques exemplaires des deux sexes. Herophydrus Ritsemae, n. sp. Long. 5 — 5'/4 mill. — Regulariter ovalis , postice paulu- lum attenuatus , parum convexus, subtiliter punctatus, for- tius in elytris et in mesosterno, brevissime et vix visibiliter jyubescens, rufo-ferrugineus , nitidulus, elytris fuscis , ad, la- tera dilutioribus ; clypei margine in medio angustiore sed nullo modo interrupto. Cette grande espèce se rapproche surtout de 1' Herophy- drus guineensis Aubé (Hydrop. turgidus Er. , hyphydroides Perris) , mais elle s'en distingue par sa taille plus grande , .Notes from tLie Leyden Museum, Vol. XI. 58 HEROPHYDRUS RITSEMAE. sa form e plus atténuée en arrière et au contraire plus élargie en avant et par sa ponctuation relativement un peu nioins grosse , mais aussi serrée ; sa coloration est aussi rooms foucée. Le clypeus présente cette particularité , unique entre toutes les espèces jusqu'ici connues, que son rebord est simplement rétréci , mais non interrompu au milieu. On remarque sur les élytres la trace d'une série ponctuée généralement peu apparente. En dessous du corps la ponc- tuation est grosse et fbrtement imprimée sur le mesoster- num , plus fine et obsolete sur les hanches postérieures et les segments abdominaux. Humpata (van der Keilen). — Quelques exemplaires. Copelatus longicornis Sharp, 1. c. p. 570. — Long. 5 mill. , parfois un peu plus ou un peu moins. — Quatre exemplaires de Surinam : Para Riv. (J. H. Spitzly), absolu- ment conformes a la description, c. a d. allonges, presque parallèles et tres peu convexes , avec une ponctuation fine et presque effacée, et trois striës dont l'externe est aussi éloignée du bord externe que l'interne l'est de la suture. La coloration est d'un roux ferrugineux, un peu plus brun sur les élytres dont la base présente une bande basilaire plus pale. Le male se fait remarquer par la dilatation tres développée des quatre tarses antérieurs et par les genoux antérieurs qui sont robustes et échancrés en dedans auprès de l'articulation tibio-fémorale. Copelatus debilis Sharp, 1. c. p. 579. — Long. 4 — 4}\2 mill. — Espèce tres variable et ayant une aire de distri- bution géographique tres étendue, car on la trouve depuis le Mexique (Guanajuato) jusqu'au Brésil meridional. Le type qui se prend dans le Mexique meridional et l'Améri- que centrale est brun assez foncé avec la tête et les cötés du pronotum roux et une bande basale fauve bien nette aux élytres qui sont pourvues, outre la strie submarginale, de cinq stries discales , dont l'interne est éloignée de la suture et qui sont d'autant plus rapprochées l'une de l'autre Notes from the Leyden Museum , Vol. XI. COPELATUS DEBILIS. 59 qu'elles sout plus externes. Les exemplaires de Guanajuato, que m'a envoyés Ie Dr. Dugès (C. obscurus E. Dug. iu litt.) , sont beaucoup plus pales et la bande basale des élytres est a peine indiquée ou mêrae null e. C'est de cette forme que se rapproche l'exemplaire que j'ai sous les yeux, de Surinam : Para Riv. (J. H. Spitzly) ; mais il a cette parti- cularité qu'il présente une sixième strie occupant précisé- ment Ie milieu du grand espace compris entre la strie interne et la suture et seulement dans la première moitié. Cette particularité , que je n'ai observée encore que sur ce seul exemplaire, fait que l'espèce peut être rangée indi- stinctement dans Ie 9e ou Ie 10e groupe de la Monogra- phic du Dr. Sharp. Du reste cette espèce n'est pas la seule qui présente une variation dans Ie nombre des stries. J'en possède une autre de la Jamaique representee par deux exemplaires; Ie male a les élytres absolument lisses, tan- dis que chez la femelle les élytres présentent en dehors cinq stries profondes extrêmement rapprochées, abrégées en avant et en arrière , et en plus deux autres rudiments de stries discales indiquées seulement par quelques points allonges ranges en série reguliere, Ce dernier insecte , la 9 > a été soumis au Dr. Sharp qui supposait que ce devait être ia femelle de son insolitus , dont les types cf sont de Cuba et San Domingo ; je partage absolument son opinion , Ie male étant en tout conforme a sa description , sauf peut- être que les tibias antérieurs ont leur bord interne indi- stinctement émarginé. Copelatus striatulus Aubé , Spec. p. 385. — Espèce tres variable, surtout quant a la forme qui est tantót large- ment ovale , tantót oblongue et allongée , et quant a la ponctuation qui est chez les uns bien imprimée et chez les autres tres obsolete , avec une reticulation extrêmement fine et également variable en intensité. Elle est caracté- risée par la presence d'une strie submarginale fortement abrégée en avant et de six autres stries discales , dont l'in- terne n'existe que dans la seconde moitié et dont les deux Notes from the Ley den Museum , Vol. XI. 60 COPELATUS STRIATULUS. externes sout tres rapprochées; récartement qui existe entre chacune des cinq premières stries a partir de la suture est Ie double de celui qui sépare la 5e de la 6e : or , sur deux exemplaires cT et Q , de Humpata (van der Keilen) , que j'ai ici devant moi., la femelle présente ce caractère extrê- ruement reruarquable qu'elle possède a la base de chaque élytre Ie rudiment de quatre stries occupant juste Ie milieu de chaque grand intervalle; cette femelle présente done en réalité dix stries. Entre l'interne et la suture, de même qu'entre l'externe et la submarginale, l'intervalle est assez large et si l'on y suppose la presence d'une strie dans chacun , on arrive ainsi au total de douze stries discales , plus une submarginale, ce qui peut être considéré comme la perfection dans la striation chez les Copelatus. Le C. Aubei Montrouz. , de Nouvelle Calédonie, présente seul jusqu'ici et au plus haut degré cette perfection dans la sculpture des élytres. Le Copelatus striatulus Aubé, a ma connaissance, a été trouvé au Senegal, a la Cöte d'or (Wydah), au pays des Achanti, dans la Guinee et au Congo intérieur, e'est a dire dans une grande étendue de l'Afrique tropicale occi- dentale. Copelatus caelatipennis Aubé, Spec. p. 382. — Quatre exemplaires de Surinam: Para Riv. (J. H. Spitzly), bien conformes a la description du Dr. Aubé. C'est encore une espèce a habitat tres étendu : Mexique (ma collection) ; An- tilles (Aubé); Guyane (Musée de Leyde); Brésil: Santa Rita (ma collection) et Espirito Santo (Sharp). Hydaticus sobrinus Aubé, Spec. p. 156, var. — Humpata (van der Keilen). — Ces quatre exemplaires constituent une interessante variété distincte du type par les irrorations noires des élytres qui sont répaudues régulièrement sans aucun point de condensation , tandisque chez le type elles se con- deusent en une bande post médiane vague et irreguliere et en une autre moins distincte antéapicale ; la forme parait aussi un peu plus allongée. Notes from the Leyden Museum, Vol. 2LI. HYDATICUS LEANDER. 61 Hydaticus Leander Rossi. — Belle série de cette espèce éminemment variable , aussi biea comme taille , que comme forme et coloration, tous de Humpata (van der Keilen). On peut y remarquer trois variétés assez tranchées. Chez la première, l0'/2 — H1/2 mill., qui se rapproche Ie plus du type, les irrorations noires recouvrent régulière- ment les élytres et c'est a peine si elles sont plus conden- sées Ie long de la suture. Chez la seconde, 10 — 103/4 mill., ces irrorations se con- densent en une large plaque suturale noire n'atteignant pas tout a fait la region scutellaire et plus largement in- terrompue en arrière; de plus Ie pronotum est plus jaune et sa bande noire basilaire est plus intense. Chez la troisième, 1 0 3/4 — 11V4 mill., qu'on serait tenté de prendre pour une espèce distincte , les élytres sont noires avec une bordure rousse autour de laquelle seulement les irrorations se désagrégent ; Ie pronotum est noiratre avec une bordure jaune qui diminue d'intensité en dedans et laisse un reflet rougeatre transversal sur Ie milieu. Hydaticus dorsiger Aubé, Spec. p. 193. — Belle série également de cette jolie espèce; ces exemplaires ne diffé- rent absolument du type de Madagascar, que par un peu moins d'ampleur dans la bande suturale noire. Hydaticus exclamationis Aubé, Spec. p. 206. — Tous les exemplaires de la série se distinguent a la bande submar- ginale jaune qui est plus étroite que d'habitude et qui est presque toujours interrompue plus ou moins longuement en arrière, de facon a laisser un point jaune terminal isolé; deux d'entre eux ont cette bande plus large et l'un des deux y possède même une tache noire humérale bien dé- veloppée.

Cependant eet insecte ne me repré- sente pas Ie grand et bel Hydaticus Petiti type, a large bande jaune plus ou moins interrompue avant sa terminai- son, que je me rappelle avoir vu dans la collection du Muséum de Paris et qui est de Madagascar. L'exemplaire dont il est question ici vient du Transvaal (E. Heyne). Cybister distinctus Régb. , Ann. Soc. Ent. Fr. 5. VII. p. clvii. — Un specimen tf de Liberia, Junk Riv. (Stampfli), tres distinct du type ordinaire du Senegal , par sa forme beaucoup plus allongée et par la dilatation des tarses an- térieurs qui parait un peu moins considerable. 11 ne serait pas impossible que ce fut une autre espèce, mais il fau- drait avoir a sa disposition plusieurs individus des deux sexes pour trancher cette question. Cybister immarginatus Aubé, Spec. p. 83. — Trois in- dividus de Humpata (van der Keilen), remarquables par leur coloration tres noire et par la grande dilatation de l'arrière corps.

Cette grande et belle espèce est tout a fait intermediaire entre les O. madagascariensis Aubé et suturalis Régb. Elle diffère du premier par sa forme plus allongée, par l'espace scutello-sutural lisse bien développé et occupant environ Ie premier cinquième de la longueur chez Ie male , un peu plus large et bifide a son extrémité chez la femelle , et aussi par la cóte plus large et moins élevée. Elle se distingue de YO. suturalis par sa forme au contraire moins allongée et moins comprimée, par l'espace scutello-sutural et la cöte moins prolongés en arrière dans les deux sexes et par la truncature plus arrondie , dont l'angle externe est moins aigu et l'interne un peu obtus ; il en résulte que la jonc- tion des deux élytres a l'extrémité de la suture forme un angle légèrement rentrant, tandis que chez l'autre espèce il est légèrement saillant.

Shortly after ray previous paper on South African Birds had left the press, our Museum received a new collection from Mr. van der Keilen, who seems still to stay at his head-quarters in the Colony of Boers at Humpata, in the Upper Cunene region. This recent collection contains the considerable number of 267 birds-skins, representing 103 different species , 49 of which are not contained in his former consignments and thus not mentioned in my pre- vious list. Of these 49 species , which in this paper will be marked with an asterisk , two proof to be new to science. All the birds are collected during the first trimester of 1888, and the only locality mentioned is Gain bos, in the Upper Cunene region. The aforesaid 49 species added to those of the former consignments , the species we hi- therto received from that country will reach the con- siderable number of 180. 1. A q uil a rap ax (Tenim.). — Two females, one of which (N°. 429) has the upper surface, sides of head and neck and the breast very dark, with but few longi- tudinal stripes of fawn-color.

In looking through the rich literature of L. melanoleucus, I find only one place (Boehm, J. f. 0. 1883, p. 168), where white- tipped centre tail-feathers are mentioned J).

Observation : A re-examination of the specimens mentio- ned in my first paper on Birds from Mr. van der Keilen, Notes from the Ley den Mugeum , "Vol. XI. 72 ON BIRDS FROM S. W. AFRICA. showed that in the specimen mentioned as having only two secondaries edged with white, this is only the case on the right wing, probably on account of the white edge of the third secondaries being worn off. At this place may be mentioned as a peculiarity that in one of the immature specimens of D. major, collected by the late Governor Nagtglas on the Gold Coast, three secondaries are distinctly edged with white. 62. Dry o scopus cub I a (Levaill.). — Two specimens. The young male and female, described in my last report, p. 234 and 235 as belonging to this species, belong to Nilaus brubru. *63.

A comparison of the specimens at hand with a fine specimen of B. murinus , kindly sent me by Prof. Barboza du Bocage , convinced me of the identity of both species.

This species , which I in vain tried to identify with any other known to me, is very similar to F. gariepensis, but may be easily distinguished by the black chest , each feather of which has a subterminal cordiform spot of white, in the same degree as this is the case throughout the whole lower surface of F. lathami. Moreover the whole upper surface has a grayer tinge , and the cross-bars are narrower, fainter and are rather mere vermiculations than real cross-bars. Ad. c? . Whole upper surface brownish gray ; the feathers on head and hind neck with broad dark brown or even blackish centres , those of the back and upper wing-coverts irregularly blotched with dark brown , narrowly vermicu- lated with buff and , especially the scapulars and inter- scapulary feathers, broadly striped with fulvous or white shaft-streaks. The outer pairs of tail-feathers are uniform earthy brown, the innermost ones and the upper tail-coverts are vermicu- lated in the same way as the back. The primary coverts Notes from the Leyden Museum, Vol. XI. ON BIRDS FROM S. W. AFRICA. 77 and the terminal half of the primaries are uniform earthy brown , the basal half of the latter shaded with vinous red, and also are the larger under wing-coverts. Like F. gariepensis this species is characterized by two bands of white and black feathers, the one running through the eye to the base of the neck, following the sides of occiput aud hind neck, the other beginning at the base of the bill and encircling the pure white chin and throat. Both bands, bordering form above and below the fulvous ear- coverts and sides of neck , terminate into a broad black jugular patch , as is the case in F. levaillanti. Each feather of this jugular patch has a white cross-bar near the base and a large and very salliant cordiform subterminal spot of the same color. The rest of the lower surface is white with a strong tinge of buff, with very large black blotches on the breast In F. gariepensis these blotches are brown. Most of the very long feathers of the flanks are reddish brown on the inner vane and barred with gray on the outer one, both parts being separated by a broad white shaft-streak. Thighs faintly tinged with vinous , uniform , vent and under tail-coverts faintly barred with grayish brown. Lower surface of tail-feathers earthy brown, like the quills. Iris reddish brown , bill horny gray, feet yellow. The female is similar to the male, the spur however is wanting. Wing tail tarsus culmen tf1 15.4 6.8 3.5 3 cm. 9 15.2 6.5 3.5 2.8 » *91.

NOTE XVII. ADDITIONAL REMARK ON FRANCOLINUS SUBTORQUATUS. J. BÜTTIKOFER. In ray first paper on Birds from S. W. Africa (N. L. M. 1888, p. 242) I mentioned a specimen of Francolinus subtorquatus from Humpata. Looking through the Franco- lins in our Museum , I found an adult female of this same species , which has been collected by Mr. Sala near Mos- samedes, on Oct. 27th 1867. Prof. Barboza du Bocage has not mentioned this species in his excellent Ornitholo- gie d' Angola. A comparison of his description of Franco- linus schlegeli (p. 407) with F. schlegelii and subtorquatus iu our Collection, convinced me, however, that the bird in question undoubtedly belongs to F. subtorquatus. The misleading note in Smith's Zoology of South Africa , about the resemblance of male and female of this species is reme- died by Mr. Sharpe in his » Birds of South Africa", p. 601. Notes from the Leyden Museum , "Vol. XI. ON MACRONOTA APICALIS. 81 NOTE XVIII. ON MACRONOTA APICALIS, G. & P. BÏ J. R. H. NEER VOORT van de POLL. Among the Macronota's described and figured in Gory and Percheron's » Monographic des Cétoines (1833)" there is a small species from West-Africa , viz. : Macronota api- calis G. & P., which, though with some doubt, was placed by the authors in the genus Macronota, composed of Asiatic species only. Our advanced knowledge of the distribution of Cetoniid genera induces us to consider the occurrence in West- Africa of a species , belonging to an exclusive Asiatic genus, a fact of much doubt. Moreover tbe figure of M. apicalis is not at all representing the peculiar facies of a Macronota, but looks much more like a Glycyphana with a slightly lobed prothorax. Burmeister, in his »Haudbuch der Entomologie 111(1842)" mentions this species , which was not known to him , no less than three times. Firstly he supposes (p. 330), that M. apicalis G. & P. does not belong to the genus Macro- nota, but probably ought to be ranged in the genus Gly- cyphana. On p. 351 , in an annotation at the end of the discription of Glycyphana impar G. & P. , he says : » I suppose, Macronota apicalis G. & P. belongs hereto." Fi- nally having established the genus Discopeltis for D. tri- color Burm. J), he writes (p. 600): »the only species I 1) Burmeister described Discopeltis tricolor from a specimen in Mr. Sommer's collection , which was obtained afterwards by Dr. Baden , and has passed now in my possession. Notes from the Leyden Museum, Vol. XI, 6 82 ON MACRONOTA APICALIS. have examined, is a native of Guinea, and therefore I suppose that Macronota apicalis G. & P. , which I have placed formerly in the genus Glycyphana as I did not yet know Discopeltis tricolor, must take its true place in this genus." In the Munich Catalogue these quotations of Burmeister are omitted. Schaum discusses the views of Burmeister in his » Obser- vations critiques sur la familie des Lamellicornis Mélito- philes (Ann. Soc. Ent. de France. 1844. 2e Sér. t. II)" and considers the characters , which distinguish M. apicalis from the genus Macronota , too trifling as to justify a se- paration. The type specimen of M. apicalis, which belonged to the collection of Count Dejean , is now in possession of Mr. J. Thomson, who has published in his »Typi Cetonidarum (1878) p. 36" a list of the types of Gory & Percheron preserved in his collection , and among them he enumera- tes a Gametis apicalis. The position assigned to this insect by Thomson , without any further explanation , neither pleads in favor of his accurate observation, nor for the homogeneity of his genus Gametis. I have failed to find any further annotations about this interesting species , which seems to be a great rarity , for although I have visited the greater part of the more im- portant Musea and private collections in Europe, I never saw a specimen of it. Great was therefore my delight, as I observed, on opening a drawer with Cetoniidae of Dr. Baden's collection , which I recently purchased , an insect which directly called to mind the figure of M. apicalis G. & P. After a careful examination with the description and figure, little doubt remained as for its identity, the only appreciable difference being the red border of the thorax, which does not extend along the front- and basal- margin in my specimen. (Here I must observe that the description and figure of G. & P. are somewhat in contra- diction, the legs being yellow on the plate, at least in ^Totes from the Leyden Museum , Vol. XI. ON MACRONOTA APICALIS. 83 my copy, whilst they ought to be black according to the description). At the same time it became evident, that Burmeister, at last , very correctly had referred this species to his genus Discopeltis. D. apicalis G. & P. is allied to D. lateralis Gerst, from Zanzibar, and to the more recently described D. aberrans Jans, from Angola , and D. capucina Gerst, from the Ca- meroons, the two latter species I know however from description only. The description of Gory & Percheron being very super- ficial and incomplete, I think it might be useful to give a detailed description of my specimen. Discopeltis apicalis G. & P.

ON THE DUTCH COAST. Dr. Th. W. van LIDTH de JEÜDE. On Dec. 8th 1888 a large fish was washed ashore near Sche- veningen, and was captured by two fishermen, who brought it to the Leyden Museum. They told us nobody in Scheveningen ever saw such a fish, and were very much surprised as we showed them a stuffed specimen of Lampris luna, captured at Noordwijk in 1840, which specimen resembled the fish they captured in all points, being only somewhat smaller. Now it is a matter of truth that Lampris luna very seldom makes its appearance on our coast. As far as I can make out this is the 5th specimen captured on the dutch coast during this century. The first is the specimen, the skeleton of which is described by G. Bakker in his work entitled » Osteographia Piscium" edited in 1822 at Groningen. In his »Praefatio" Bakker states that his specimen was captured at Katwijk during the summer fifteen years ago l). In 1836 a second specimen of Lampris luna was washed ashore at Noordwijk. A coloured figure of that specimen in possession of Mr. F. A. Verster van Wulverhorst, the admini- strator of the Leyden Museum, who got it from his father, is now in our library. Moreover Mr. Verster van Wulverhorst Sr. made an annotation in his copy of » J. A. Bennet en G. van Olivier, Naamlijst der Nederlandsche Visschen" stating the 1) In «Bouwstoffen voor eene Fauna van Nederland" this fish is erroneously stated to have been caught in 1822 at the coast of Groningen.

The third specimen is that above referred to, captured at Noordwijk in 1840, stuffed and making part of the Leyden Museum. The fourth is a fish captured on our coast on Dec. 1844, the skeleton of which is preserved in our osteological collection. Our new specimen from Scheveniugen is a female, long 103 cm., high 65 cm. and weighing 54'/2 K.G. On examining the contents of the intestines a shrimp was found in the oesophagus, and the stomach was filled up with cuttlefish-jaws. As the fish was in a very good condition we tried the flesh and found it excellent, much resembling that of salmon. The skeleton of this specimen will be placed in the osteolo- gical collection of the Leyden Museum. Notes from the Leyde- IMuseixoa, Vol. X.1. MALAYAN CICADIDAE. 87 NOTE XX.

Thomson. Thibetana Westvv. = Mellyi Westw. Thibet", but this determination certainly is incor- rect. The specimens from Mr. Janson's collection have been examined by Mr. Olliff , and one of the females has been figured in the Cistula Entomologica (III. pi. 3, fig 1). The other species, which has the anterior elytral spot between the 4th and 6th , and the posterior spot between the 3rd and 6th striae, is the species the male of which has been described by Mr. R. Oberthu'r under the name of Helota curvipes. Besides the two type-specimens , which have likeAvise been examined by Mr. Olliff and one of which comes from the Himalaya , I have before me a third male from North India from the collection of Mr. Sédillot, and a female specimen from Tenasserim (brought home by Mr. Fea) and belonging to the Genoa Museum. Guerinii Hope and curvipes Oberth. , though closely allied , are not only distinct by the different position of the elytral spots: in curvipes the fulvous colour of the anterior angles of the pronotum is indistinctly continued along the lateral margins of the thorax , the punctuation on the pronotum is less dense, and the row of strong punctures which is present on the interstices of the external half of the elytra in Guerinii is absent in curvipes. Moreover the apices of the elytra in the females are much more produced and more acutely pointed in Guerinii than in curvipes. As to the Javanese Helota ocellata Rits. , of which only a female (the type-specimen) is known to me , it has a shorter and broader form , a much brighter colour on the upper surface (bright golden green , with coppery tinges at the sides of the pronotum and around the elytral spots), the elytral spots proportionately large, the anterior one appa- rently between the 3rd and 7th, but in reality between the 4th and 7th striae , the posterior one between the 3rd and 7th striae , and the fulvous colour of the anterior angles of the pronotum indistinctly continued along the lateral margins of the thorax. The apices of the elytra are less produced than in the female of Guerinii, but more acutely pointed than Xotes from the Leyden Museum, Vol- XI. ON THE GENUS HELOTA. 107 in that of curvipes , and the interstices on the external half of the elytra are not provided with a row of strong punctures. Helota f ulvitarsis, nov. spec, cf and Q. Very closely allied to and strongly resembling the Java- nese Helota semifulva Rits. with which it is united by Mr. Sidney Olliff. I feel sure, however, of its specific di- stinctness , which might be already presumed by the diffe- rence of the countries from which they come: Bengal (Darjeeling) and Java. The new species is proportionately broader , the punctu- res on the pronotum are distinctly larger, the flattened lateral margins of the elytra are broader, the tarsi are of a pale fulvous colour (dark pitchy brown in semifulva) , and the fulvous colour of the basal half of the elytra is continued over the flattened lateral margins much farther than in semifulva. The elytra are conjointly rounded, both in male and female , but the male has the anterior tibiae strongly curved, and its apical ventral segment is incon- spicuously depressed in the middle before the apical mar- gin , which depressed portion is very densely and finely punctured and hairy. — Length of the male 8 mm., that of the female 9,5 mm. Hab. India orient. : Darjeeling. — A male and a female in the collection of Mr. René Oberthür , who possesses also a female specimen of Helota semifulva Rits. , the second specimen of this species with which I am as yet acquainted , and which comes, like the type-specimen , from Mt. Ardjoeno (Java orient.). The specimen from » India" in the collection of the British Museum, alluded to by Mr. Sidney Olliff under the name of Helota semifulva Rits. (Cist. Ent. III. p. 55) , will , no doubt , prove to belong to Helota fulvitarsis. Notes from the Ley den Museum, Vol. XI. 108 ON THE GENUS HELOTA. H e I o t a guineensis, nov. spec. Q. Closely allied to Helota africana Olliff l) from Angola, and strongly resembling it. The two specimens before me, which come from Accra and Assinie (Guinea coast), show, however, some differences which induce me to believe it a distiuct species, but as the type-specimen of africana is unknown to me, I can compare my specimens with the description and figure only. In the new species the thorax is shorter and broader and the sides are decidedly rounded ; the punctures are widely and irregularly spread, and those on the sides are as large as those on the middle; the black median streak is laterally emarginate on its anterior half; the base of the thorax as well as that of the elytra is very narrowly edged with black. Of the elytra the smaller apical half is black with a deep triangular notch at the suture , the two elongate black spots on the fulvous basal half are absent, and the apices are more acutely pointed. The legs are black , with the exception of a broad fulvous ring at the basal half of the femora , and a more or less distinct spot on the middle of the under surface of the tibiae , which is of the same colour. The last ventral segment shows an ill-defined impression along the middle, and its apex is indistinctly truncate. — Length 13 — 14 mm. Hah.

As to the coloration it differs from africana (according to the description and figure) in having the black elytral spot between the 3rd and 4th striae more elongate and the line of demarkation between the fulvous and black colour very irregular, while it is nearly straight in the figure of africana. Moreover the legs are black or dark pitchy with a very irregular fulvous ring at the base of the femora. The head, thorax and scutellum correspond pretty well with the description of africana; the fulvous sides of the thorax, however, are not finely but very coarsely punc- tured , leaving free an elongate raised spot. The elytra are, as in africana, half as long again as the head and prothorax together but proportionately narrower and slightly tapering towards and conjointly rounded at the apex; they are somewhat dehiscent at the suture , and the apical mar- gin is minutely bisinuate in each elytron. The interstices are alternately costate; the first (sutural) and second costae, however , become flat towards the base, and the second and fifth ouly join the apical margin ; the third costa is some- what shorter than the fourth , and the fifth does not reach the basal margin ; the punctures of the striae become lar- ger the more they approach the lateral margins. Between the 3rd and 6th striae, just before the black apical half, an oblique callosity of a somewhat paler colour is present. The anterior tibiae are curved, without compressed dilata- tion at the apex ; the posterior femora rather slender and slightly curved. The first ventral segment is shallowly im- pressed along the middle ; the fifth broadly truncate and provided with a large but shallow semicircular impression which is neither punctate nor tomentose. — Length 15 mm. Hab. East Africa: Zanzibar. — Of this very interesting species three specimens have been sent to the Berlin Mu- seum by Mr. C. W. Schmidt, and of these Mr. Kolbe has been good enough to let the Leyden Museum have one. .Notes from the Leyden Museum, Vol. X.1. 110 ON THE GENUS HELOTA.

SUR UNE ESPÈCE MÉCONNUE DU GENRE MACROMA. PAR J. R. H. NEERVOORT van de POLL. Il y a seulement quelques mois, que j'ai eu la boune chance d'obtenir d'uii de mes correspoudanis en Sumatra central , uu exemplaire de la rarissirne Macroma gloriosa Mohn., exemplaire qui se rapportait parfaitement a la de- scription soignée du Dr. Mohnike. Tout récemment, je viens de recevoir par l'obligeance du Dr. Gestro , un pre- mier lot des doubles des cbasses de M. Fea en Birmanie, et j'y trouve une Macroma, déterminée aussi gloriosa Mohn. Malgré la localité contineutale, cette determination ne m'offrait a première vue rien d'extraordinaire. La presence de la coloration si caractéristique semblait exclure tout doute. Ce ne fut qu'un peu plus tard , en voulant l'intercaler dans ma collection auprès de son confrère insulaire que je fus frappe par quelques particularités qui nrengageaient a les comparer plus sérieusement. Le résultat de eet examen fut, que je me trouvais saus aucune doute en presence de deux espèces tres distinctes , quoique voisines. Tout d'abord je consultais de nouveau l'ouvrage de Moh- nike. Il n'y avait rien a redire. Sa description s'accordait de point en point avec mon individu insulaire. Done l'espèce Birmanienne devait être quelque chose de nouveau. Me rappelant que M. Gestro avait publié , dans sa pre- mière notice sur les captures de M. Fea, quelques anno- tations a propos de la M. gloriosa Mohn., j'espérais y trouver Notes from the Leyden Museum, Vol. XI. 14'2 MACROMA. l'information désirée. Malheureuseraent cette notice, a part la communication de la localité precise, se bornait a la phrase suivante : » è facilissiraa a determinare coll'aiuto dell'ottima figura di Westwood , mentre quella di Mohnike sembra fatta espressamente per mettere nell' imbarazzo." Il ne me restait done plus que de consulter Ie „Thesaurus Entomologicus" de M. Westwood. Mon exemplaire Birma- nien se rapportait si parfaitement a la figure de Westwood , comme si celle-ci avait été peinte d'après lui, et ainsi la description était tout a fait exacte pour toutes les parti- cularités caractéristiques. Mais cela n'a rien de bien sur- prenant quand on sait que Westwood n'a pas connu la forme insulaire décrite par Mohnike, et que l'individu qui lui a servi pour son étude, était l'exemplaire de la collec- tion W. W. Raunders , capture par Mouhot en Siam. Voici done la solution, la Macroma gloriosa Westw., n'est pas du tout identique avec la Macroma gloriosa Mohn.! Le Prof. Westwood a commis la faute grave de ne pas avoir consulté la description de Mohnike. S'il eüt pris la peine de lire cette description détaillée, il n'aurait pas manqué d'observer que la M. gloriosa Mohn. n'a point une tête »very delicately granulose," ni la carèue de la callo- sité apicale des élytres » scalloped into four teeth," et non plus le dessous uniformément noir ! M. Gestro , par cette complication, a été induit en erreur, il a trouvé, et pour cause, son espèce mieux en rapport avec la figure de Westwood et en a conclus que la figure de Mohnike était peu exacte. Les planches de Mohnike ne sont pas hors ligne , pourtant cette fois-ci , l'opinion défavorable du Dr. Gestro est non méritée et trop sévère. Comme je l'ai déja dit, la description de Mohnike est tres complete, et celle de Westwood est aussi suffisante, il serait done inutile de décrire ici de nouveau ces espèces. Je me bornerai pour faciliter des recherches ultérieures, a relever les differences entre ces deux espèces voisines, en imposant a l'espèce Birmanienne le nom de Macroma superb a v. d.

ON THE LONGICORN GENUS ORION, GUÉR. BY C. RITSEMA Cz. In the „Genera des Coléoptères" (VIII, p. 300) Laeor- daire, in accordance with Guerin's views, ascribes to the female of Orion patagonus Gruér. a prothorax which is more strongly rugose than in the male and the callosities of which are less numerous and but little conspicuous. Now the Leyden Museum possesses two specimens of 0. patagonus (one from Magellan: Patagonia, the other from Cordoba: Argentinia) which, no doubt, are male and female , but these two have the thorax quite similarly sculptured. The male , however , is smaller and of a some- what brighter colour; it has the antennae somewhat longer, and the apical half of the elytra subshining in consequence of its being rather vaguely sculptured ; in the female , however, the apical half of the elytra is opaque coriaceous. Moreover the Leyden Museum has a third specimen of this genus (from Santa Lucia : Uruguay) which almost ex- actly corresponds with the figure given in the „Atlas" belonging to Lacordaire's „Genera" (pi. 86, fig. 1) under the name of Orion patagonus. In this specimen the thorax is very strongly rugose, its callosities are but little con- spicuous, and its lateral spines very slender, whilst the elytra are more coarsely rugose and have the costae slightly more distinct. I suppose this to be the form considered by Guérin and Lacordaire as the female of patagonus, but as, in my opinion, it is specifically distinct from that species I propose to call our Uruguay insect Orion La- cordairei. Orion brunneus Guér. most probably will prove to be founded on a male specimen of patagonus Guér. Notes from the Leyden Museum , "Vol. XI. BRITISH GUYANA BIRDS EGGS 145 NOTE XXX. ON EGGS OF SOME BRITISH GUYANA BIRDS. BY Dr. C. G. YOUNG. 1. Nyctidromus albicollis (Gm.) '). Goat Sucker , Jumbi Bird. They make no nest but lay their eggs in a depression in the ground where it is dry, on the beds of cultivated land, on the high dams between plantations, on the bare rocks up the rivers, and on the savannahs in the „Interior". They lay two or three eggs. The egg is smooth, regularly oval — 30 mm. by 22 mm. — , light pink with darker pink blotches. They hatch from March to July. — One egg (N°. 1). Although I kept all the eggs in the dark , the above mentioned one has much faded during its being in my pos- session. 2. Progne chalybea (Gm.). Swallow. They build a flat nest of coarse grass and fine sticks , lined with a few leaves, on the beams about houses. 1) Excepting three Herons and the two species of Tinamus, all the eggs, pre- sented to our Museum by Dr. Young, have been accompanied by birds skins of the species the eggs belong to, and therefore identification is rendered quite easy and unmistakable. J. Büttikofer. Note* from the Leyden Museum , "Vol. XI. 10 146 BRITISH GUYANA BIRDS EGGS. Although a number of nests are found at the same time on the same beam they are not sociable. They lay three eggs. The egg — 25 mm. by 16 mm. — is white. They hatch from May to August. — One egg (N°. 8). 3. Fluvicola pica (Bodd.). Cottou Bird. The nest is covered in , almost round like a ball , made of grass , and suspended from the extremity of the branch of low trees and shrubs, four or five feet from the ground. The place of entrance is near the attachment to the branch. Sometimes the nest is built in a thick bush when the lower part of the nest rests on the branch beneath. They lay two eggs. The egg — 18 mm. by 12 mm. — is cream white with a few reddish brown spots at the large end. They hatch from January to May. — One egg (N° 5). 4. Pitangus sulphuratus (Sw.). Kickadu. They make a domed nest, which is very rough on the outside and more like a wisp than a birds nest, of grass, pieces of cotton , and old rags when they can get them , on the extremity of the branch of low trees and shrubs a few feet from the ground, or on the outer branches of forest trees fifty or sixty feet from the ground ; they never build in the heart of the tree near the stem , except when they build on palms. They lay four eggs. The egg — 29 mm. by 21 mm. — is cream, spotted on the large end with light and dark brown large and small spots; there may be a few small spots here and there over the rest of the egg. They hatch from January to August. — Three eggs (N°. 6). Notes from the Leyden Museum, Vol. XI. BRITISH GUYANA BIRDS EGGS. 147 5. Cassicus persicus (L.). Sawacco, Mocking Bird, Oriole. They build in colonies and make a hanging nest of grass , tendrils of crisping plants, and strips torn from the leaves of the cocoanut palm , from the end of the branches of trees or low bushes, if the latter hang over water. They keep on the lea side of the tree. The distance of the nest from the ground depends a great deal oo the locality , and is from eight feet on low bushes , to fifty or sixty feet on tall forest trees. The nests are about eighteen inches long and four inches in diameter and are very uniform in shape and size. The shape is like a bag closed in at the top , with the en- trance in the side near the attachment to the branch. The sides round the entrance project a little, forming a funnel. The bird builds from the inside and finishes the nest in from eight to ten days. They lay two, rarely three eggs. The egg — 30 mm. by 20 mm. — is white with a slight shade of blue , and may have a few light brown and violet spots at the large end , or a great many similar spots distributed over the entire surface. They hatch from January to June, and if the year has been dry build again in October and November. If the first months of the year are very wet , their building ope- rations are delayed. — Two eggs (N°. 17). 6. Cassicus af 'finis , Sw. They build in colonies and make a nest like the nest of Cassicus persicus , on the same tree sometimes , but never on the same branch. They lay two eggs. The egg — 30 mm. by 21 mm. — is bluish white, thickly covered with light purple spots, more numerous at the large end , with a few light brown spots here and there. Notes from the Leyden Museum, Vol. XI. 148 BRITISH ÜUYANA BIRDS EGGS. The egg is distinguished from that of N°. 5 by having more spots and the spots being more uniform in tint. They hatch from January to June. I have not seen them build in October. — One egg (N°. 18). 7. Icterus xanthornus (Gin.). Yellow Plantain Bird. They make a hanging nest of grass, like a bag, with an open mouth , from the end of branches of trees or low bushes. The nest is generally about eight or ten inches long , but may be eighteen inches long , and three or four inches in diameter. The bird builds from the inside and outside alternately , and as a consequence the nest is smooth on both sides. They do not build in colonies , although two or more nests are found on one tree. They lay three eggs. The egg — 25 mm. by 17 mm. — is white, having light violet and black irregular lines about the large end, the black lines commence with a spot. They hatch from January to July: if the spring is wet they hatch later. - Two eggs (N°. 19). 8. Rhamphocoelus jacapa (L.). Black Sackie. The nest is open like a cup and built of twigs and dry leaves , especially the leaves of the bamboo , and lined with coarse fibres. They build in the centre of low thick bushes or in the fork of a branch of moderately high trees. Some nests are made of brown materials — brown twigs , brown leaves , and brown fibres — resem- bling the colour of the bird. They lay three eggs. The egg — 21 mm. by 18 mm. — is greenish blue, spotted with black and purple spots , the former being more Notes from tlie Leyden Musenm, Vol. XI.

Old Witch, Keel-bill. Some eight or ten birds build an oval , shallow , open nest, about eight inches long and four inches wide, of sticks, lined with leaves, in the centre of low bushes, es- pecially in orange trees , a few feet from the ground. This nest is used in common, and when they are hatching , five or six birds sit on the nest at the same time. Twenty eggs have been taken out of one nest. The egg is regularly oval — 38 mm. by 27 mm. — , smooth , and white in colour : if the egg is scratched it leaves a light green mark , the colour of the inside of the shell. The size of the egg varies considerably in the same nest, probably due to the difference in age of the mem- bers of the colony. They hatch in March , April and May. — Three eggs (N°. 7). 10. Parra jacana, L. Spur-wing. They build a deep open nest of grass and roots among the water plants on the unused canals , swamps , aud edges of the creeks. They lay four eggs. The egg — 30 mm. by 23 mm. — is yellowish brown, thickly covered over with black irregular lines. They hatch in April, May and June. — Two eggs (N°. 4). 11. Arde a candid issima, Gm. White Gaulding.

These three herons build a nest like the nest of Nyctico- rax violaceus (L.) mentioned sub N°. 15, in the same loca- lity, at the same time, and often on the same tree. Once in a way isolated nests are found in the low bushes that fringe the creeks. They lay two or three eggs. The egg is light green, but varies much in shade as well as in shape and size, the length being about 42 mm. and the breadth about 30 mm. : some eggs are almost round. It is not possible to identify the egg by inspection alone : their eggs and the egg of N°. 14 can be distinguished by size only. 14. Butorides g riseus (Bodd.). Ardea scapularis , 111. (Schleg. Mus.

La découverte de cette nouvelle espèce fut faite a l'oc- casion d'une revision des Ornithoptera a ailes supérieures noiratres et a ailes inférieures jaunes , se trouvant clans la collection du Musée d'Histoire Naturelle de Leyde, dans celle de la Société Natura Artis Magistra a Amsterdam et dans les collections réunies de Mr. Piepers et de moi. A cette revision , entreprise dans Ie but d'arriver a une de- termination uniforme de notre material assez considerable qui comprend peut-être 200 a 250 individus appartenant a ce beau groupe , prirent part Mr. Ritsema , Ie conserva- teur du cabinet entomologique du Musée de Leyde, Mr. Swierstra , celui de la collection d'Artis , Mr. Piepers et moi-même. En premier lieu je dois observer que c'est Mr. Ritsema qui découvrit les deux principaux caractères de la nouvelle espèce; pour cette raison et aussi afin de lui marquer notre reconnaissance pour la constante bienveil- lance avec laquelle il vient toujours en aide a ses collè- gues dans leurs recherches, nous avons voulu lui dédier notre nouveauté. Le Papilio Ritsemae appartient a la section du Pap. Amphrysus et a même assez de ressemblance avec cette es- pèce dont le cf est figure par Cramer , Pap. Exot.

En- suite, la couleur jaune des ailes inférieures s'étend jusqu'a la base de l'aile , en occupant chez Ie <ƒ toute la cellule discoïdale et entièrement la cellule 7e, tandis que chez la Q Ie noir qui se trouve dans cette cellule est limité hori- zontalement. Le bord interne des secondes ailes n'est noir dans les deux sexes que jusqu'a la nervure anale ou pre- mière , le liseré noir en feston du bord postérieur est étroit et les échancrures de ces ailes ne sont pas marquees de blanc. De plus , Tangle anal des ailes postérieures est ar- rondi, non allonge dans le sens du corps comme chez le Papilio Rhadamanthus et ses allies. Les antennes , la tête avec les palpes peu développés , la moitié dorsale du thorax et les pattes sont d'un noir uniforme dans les deux espèces; ce n'est que rarement que l'on apercoit un collier rouge peu prononcé et quelques tra- ces de taches rouges sur la poitrine. Les longs poils qui chez le male ornent le bord interne ou abdominal des ailes postérieures en dessous, sont d'un brun roux bien décidé, non pas uoirs , et la frange des ailes supérieures est mar- quee de blanc dans les cellules. Ceci sont les caractères communs aux deux espèces et qui les distinguent suffisamment de toutes les autres espè- ces ou variétés d'Ornithoptera de la division qui nous oc- cupe. 11 me reste maintenant a indiquer les differences en- tre le Pap. Amphrysus et la nouvelle espèce. D'abord le Pap. Ritsemae est en general plus petit. En mesurant six cTcT & Amphrysus je trouve pour la longueur de leur aile antérieure droite: 76, 78, 80, 83 et 84 millim. Un indi- vidu exceptionnellement petit n'atteint que 63 mm.; quatre 99 ou* 83, 87 et 95 mm. Cinq cfcf de Ritsemae atteig- nent 65, 67, 68 et 70 mm., trois 9 9 prises par Mr. Piepers, 77, 79 et 84 mm. Le plus grand cT d'Amphrysus est de Borneo, il mesure 84 mm., la plus grande 9 de Sumatra (Deli), 95 mm. Les ailes antérieures sont chez Ritsemae (f d'une nuance Notes from the Leydon Museum, Vol. .XI. PAPILIO RITSEMAE. 155 moins franchement noire , plus brunatre , mais cliez les fe- nielles des deux espèces je n'apercois pas de difference sen- sible a ce sujet. La couleur du fond est chez Ie sexe faible des deux espèces d'un brun terreux bien plus clair que chez Ie cT. Les rayons clairs — d'un jaune d'or chez Am- phrysus cf ou blanc sale uniforme chez sa Q, tandis que chez Ritsemae cf ils sont d'un jaune pale et verdatre, chez la 9 d'un blanc jaunatre sale qui passe au jaune ver- datre clair a mesure qu'on approche du bord interne — sont , dans les deux espèces , disposes d'une maniere un peu différente. L'espace noir qu'ils limitent chez les deux sexes ft Amphrysus est coupé presque horizontalement en haut, c'est-a-dire du cóté qui regarde Ie bord antérieur ou plu- tot Ie sommet de l'aile, tandis que chez Ritsemae il est en eet endroit visiblement incline vers Ie bord postérieur. Le fond des secondes ailes est chez Amphrysus d'un jaune d'or brillant, a peine plus pale chez la Q, avec les nervu- res finernent dessinées en noir chez le <$ et avec quelques poils noirs , longs et soyeux vers la base de l'aile. Chez Ritsemae le fond jaune a une teinte verdatre bien sensible, la base est plus velue et plus pale chez la Q, les nervures noires sont bien plus épaisses et cela non pas seulement chez la Q, le noir du bord intérieur déborde chez les deux sexes un peu dans la cellule V°, ce qui ne se voit pas du tout chez Amphrysus, ensuite on apercoit chez Ritsemae cf dans les cellules 3 — 6 des taches noires, pointues vers la base de l'aile , plus ou moins distinctes , toujours un peu nébuleuses. La tache noire de la cellule 5e est persistante chez tous les males que j'ai vus (environ une dizaine) aussi en dessous. En outre , parmi les dents du bord postérieur , celle qui se trouve au bout de la cellule 5e est chez Rit- semae (ƒ bien plus saillante que les autres; elles sont d'ail- leurs toutes bien accusées, non arrondies et égales comme chez Amphrysus cT. Chez Ritsemae Q les dents sont éga- les. En dessous, j'observe que la nervure 8e des ailes pos- térieures est forteraent courbée sur tout son parcours chez Amphrysus , surtout chez le (ƒ, et la cellule 7e fort large, Notes from the Leyden Museum, "Vol. XI. 156' PAPILIO RITSEMAE. tandis que cette nervure s'écarte a peine de la ligne droite chez Ritsemae passé son premier tiers et que la cellule 7e n'est pas plus large que la 6e. Un caractère, a mon avis capital , se voit sur Ie dos de 1' abdomen du (f de Ritsemae, c'est~a-dire deux verrues pla- tes , allongées, rappelant par leur forme les cocons du genre Nepticula ou les Coccides. On les trouve sur Ie 3e et 4e anneau; rien d'analogue ne se voit chez Amphrysus <ƒ• Le dessus de l'abdomen est du reste chez Ritsemae d'un brun terreux foncé, uniforme chez la 9> plus clair et plus rougeatre au milieu chez le (ƒ. Chez Amphrysus Q la par- tie dorsale de l'abdomen est également d'un brun uniforme mais très-pale , tandis que chez le <ƒ les quatre premiers an- neaux sont d'un brun d'ocre terne et pale , et le reste , comme les flaucs et le ventre entier , chez les deux sexes d'un jaune d'or avec une rangée de points noirs de chaque cóté. Chez Ritsemae d" et Q les flancs de l'abdomen sont d'un vert jaunatre, aussi marqués de points noirs et le dessous seu- lement est jaune. Les valves anales des males sont d'un blanc brunatre chez les deux espèces. Jusqu'ici, le Papilio Ritsemae ne nous est parvenu que des regions montagneuses de l'ouest et du centre de Java (Preanger, Ardjoeno) oü il vole a une hauteur de 1600 — a 1800 metres. Quant au Pap. Amphrysus que Cramer dit venir des environs de Batavia , il ne se trouve pas la , puis- que Mr. Piepers, pendant son long séjour dans cette ville , n'y a jamais observe ce grand papillon. Cependant, comme le Musée de Leyde possède quelques individus etiquettes »Java", il se pourrait qu' 'Amphrysus vole a Java a une hauteur de 800 a 1500 metres oü Mr. Piepers a fait peu de chasses. Ce Musée , et aussi celui d'Amsterdam , possède plusieurs exemplaires (['Amphrysus venant de Sumatra oü il ne paraït pas être rare , mais tous sont sans indication de la hauteur oü ils furent pris. En outre, a Leyde on a un cT, venant de Borneo (Banjermassing , voyage S. Muller), qui diffère des males de Sumatra par l'absence de la tache claire au bout de la cellule des ailes antérieures. Ceci lui donne Notes from the Lcyden Museum, Vol. XI. PAPILIO RITSEMAE. 157 un aspect différent. Mr. de Haan a du reste déja signalé cette variété de Borneo dans son traite sur les espèces du genre Papilio des Indes Orientales. Le Dr. Boisduval , dans sa description du Papilio Am- phrysius (Species General, I, p. 178), confond les deux espè- ces Amphrysus et Ritsemae, mais la figure réduite qu'il en donne (PI. 5 (1 B) f. 1) se rapporte a la première espèce. Le Dr. Boisduval dit que les ailes postérieures d'Am- phrysius Q deviennent presque blanches vers la base. Ceci est surtout vrai pour le Pap. Ritsemae Q mais seulement pour les individus tant soit peu défraichis. Le Papilio ruficollis Distant, Rhopalocera Malayana, p. 328, pi. 27 f. 1 cf, fig. 107 (dans le texte) 9, pi. 27a fig. 1 Q variété , est complètement identique avec le Pap. Am- phrysus de Sumatra, et c'est bien étonnant que eet ento- mologiste distingué ne s'en est pas apercu. Les originaux de ma description du Papilio Ritsemae se trouvent a Leyde, a Amsterdam et a Rotterdam , dans les collections mentionnées plus haut.

Among a few insects from Goldie-River, New-Guinea (30 miles inland from Port Moresby), I obtained an Ero- tylid, which proved to belong to the newly erected genus Euzostria Gorh. (Notes from the Leyd. Mus. X, p. 140, pi. 7, fig. 6) founded upon a single specimen of a new insect from the Aru-Islands. The comparison of my spe- cimen with the description of this species {E. aruensis Gorh.) , offering several differences , I was inclined to re- gard my New-Guinean insect as a closely allied but dis- tinct species. However, after a careful examination of the type-specimen , I think it will be better to consider the New-Guinean form as a variety, at least provisionally, until the arrival of a more extensive material shall allow us to obtain certainty. As the spotted thorax of my specimen gives the insect a quite different and peculiar aspect, I propose the name binotata v. d. Poll for this variety, which may be characterized as follows. The face between the eyes is nearly impunctate. The thorax is less convex , the anterior angles are broader, the disc is ornated with two round black spots , and the base narrowly edged with black , more broadly so in the middle, which makes the thorax apparently shorter. The large punctures are less numerous but larger, the small punctures on the contrary still finer. The yellow band of the elytra is narrower at the suture, i. e. the band of each elytron is more triangular. Moreover, the rows of piceous dots on the yellow band, which are very distinct in the type, are hardly visible in the variety. Finally the colour of the thorax , of the apical elytral spot and of the two last ventral segments is dirty yellow instead of deep red. Notes from the Leyden Museum , Vol. XI.

CONTRIBUTIONS TOWARDS THE KNOWLEDGE OF THE ANNELIDA POLYCHAETA. Dr. R. HORST. Ill !). On species of Nereis , belonging to the sub-genus Perinereis. (Plate 7 and 8). The sub-genus Perinereis, according to Grube's views, contains all Nereis -species , characterized by having the lateral dorsal paragnathi of the basal ring of the proboscis (group VI) all or some of them transverse , ridge-shaped , the remaining paragnathi being conical, or pin-shaped (»pectiniformes" Kinberg), or compressed; the feet all of the same structure, or those of the posterior region of the body more enlarged. This division mainly corresponds to Kinberg's family Aretidea, and not to his genus Perinereis , con- taining the species , which have no pectiniform teeth and but little modified posterior feet. However it seems prefer- able to me to maintain Kinberg's name , as I do not like to increase the systematical literature with a new one, and because the greatest number of species of the family Are- tidea are united in the genus Perinereis , the four other genera {Arete , Pseudonereis , Paranereis and Naumachius) containing only a small part of them. To use the name Lipephile, afterwards proposed by Malmgren for N. cultri- fera , instead of Perinereis , as done by Claparède a. o. , seems not justified to me, because the name Perinereis has the priority , and moreover the name Lipephile is applied 1) For Part I see Vol. VIII, p. 157, and for Part II Vol. XI, p. 37. Notes from the Leyden Museum , Vol. XI. 11 Wl ANNELIDA POLYCHAETA. by Claparède in a sense different from what it was in- tended for by its author. I prefer to base the subdivisions of the genus Nereis rather on characters taken from the arrangement of the paragnathi , than on the state of development of the dorsal lobe of the feet. The main groups of paragnathi of the proboscis are rather constant and appear not to be liable to much variation in the same species ; moreover the know- ledge of their arrangement enables us to recognize also the systematical position of the Heteronereis- iorms. On the contrary the lobes of the feet are liable to much variation in different regions of the body, and show such marked changes in individuals coming to sexual maturity , that I do not think it advisable to rely much upon their characters for classification. Besides the specimens of our Museum , I could also exa- mine the Annelida collected by Prof. E. van Beneden , during his stay on the coast of Brasil, in the Gulf of Rio de Janeiro, and already described by Dr. Armauer Hansen '); I am much obliged to the Director of the Museum of Liège for allowing me to examine them, as Hansen's descriptions are as well very incomplete as inaccurate and our knowledge of local faunas being rather scanty. This interesting col- lection contains two species belonging to the group Peri- nereis, N. ferox Hans, and N. minor Hans.; in the present note I will publish a detailed description of them. Three other species : N. obscura Hans. , N. coerulea Hans, and N, microphthalma Hans., will be shown to be mere synonyms. Nereis cultrifeva Gr. 2) — Ehlers , Borstenwürmer , p. 461, pi.

I examined three specimens from Napels and one indivi- dual from the coast of Portugal (Villa Nova de Milfontes), collected by Prof. M. P. d'Oliveira. The last worm measures 10 cm. in length, while the number of its segments amounts to 102. In group I. its proboscis has two paragnathi, a large tooth preceded by a smaller one, whereas in the Napels specimens there occurs only a single tooth. Our individuals do not agree in all regards with Ehlers' description ; f. i. the anal cirri are much longer than indicated by Ehlers, reaching as far as the posterior 11 segments; the tentacular cirri are also longer. According to Ehlers' description they should reach the 5th ring , whereas in our specimens they reach the 7th and 9th segment. In the structure of its feet the Portu- guese worm differs somewhat from the Napels specimens, and agrees better with the figures of Audouin and M. Ed- wards J) , than with those of Ehlers ; the inferior ligule is longer, and extends somewhat beyond the tip of the ven- tral setigerous lobe. As first was demonstrated by Clapa- rède , and afterwards confirmed by Langerhans 2), there oc- cur in the inferior fascicle of the ventral lobe some hete- rogomph setose bristles.

As in other epitocous forms the eyes are very large; the tentacular cirri appear to be somewhat longer than indicated by Claparède , at least the longest of the superior pair of them extends rather far beyond the tip of the palpi, and reversed they reach the 5th segment. The ligules of the anterior feet are not so acute as figured by Claparède , but have a more obtuse tip. Only homogomph setose bristles are present. At the 20th segment commences the remarkable change in regard to the structure of the feet. The superior ligule has its base greatly enlarged and bears near the origin of the dorsal cirrus an oblong oval lamella; moreover a small narrow lamella occurs at its ventral side. The anterior lip of the dorsal setigerous lobe is largely produced and bears near its base at the ventral side a small oval lamella. The inferior lobe is furnished with a large lamella, at the dor- sal side extending along its total length , at the ventral side embracing only its distal end. The inferior ligule is faintly curved in a hook-like manner, with an obtuse papilla near its base. The ventral cirrus is provided at its superior margin with two small tongue-shaped lamellae , at its inferior border with an oblong oval one. At one third of the length of the body the superior ligule of the feet commences to elongate gradually , attaining posteriorly that considerable size, which is described and figured by Claparède; at the same time the lamelliform processes of the feet decrease, first those of the dorsal ligule, then those of the seti- gerous lobes and finally those of the ventral cirrus.

A dark brown patch on the dorsum of each foot , usually also a transverse stripe on each side of the segment; ventral side of the foot marbled with blackish. Cephalic lobe longer than broad, antennae subulate, hardly as long as half the length of the head ; palpi large, projecting far beyond the antennae. The antero-posterior diameter of the buccal segment about one and a half the length of that of the succeeding one ; tenta- cular cirri short, the inferior pair of them shorter than the palpi, the longest of the superior pair projecting a little beyond the tip of the palpi, reversed they reach the 3rd or 5th ring. The anal cirri, situated at the ventral side, as long as the posterior six segments. The feet in front and posteriorly not quite similar. In the anterior feet the lip of the dorsal setigerous lobe bluntly conical, the lips of the ventral lobe very short, not projecting; the superior ligule of the same structure and length as the dorsal lobe , the inferior ligule a little shorter; dorsal cirrus not extending beyond the tip of the superior ligule, ventral cirrus reaching to the middle of the inferior ligule. In the posterior body- region the superior ligule of the feet is considerably en- larged , consisting of a large lamella , which bears near its tip the small dorsal cirrus ; the conical lip of the dorsal lobe reaches only to about the middle of its ventral bor- der; the lips of the ventral lobe are more projecting than in the anterior segments, nearly as far as the inferior ligule. In the dorsal lobe there occur only homogomph setose bristles; in the ventral lobe the superior fascicle contains homogomph setose bristles and heterogomph falcate ones, but in the inferior fascicle the setose bristles are wanting. In the epitocous form the anterior 19 segments do not show any change.

Of this species I examined five examples , three atocous and two epitocous females; they were collected by Prof. M. P. d'Oliveira near Buarcos , la Granja and Sines. The epito- cous forms differ from the other ones by their large dimen- sions; unfortunately these specimens are incomplete, one of them wanting the posterior body-region , whereas in the other worm this region is partly regenerated. At the 20th segment the change of the feet occurs. The superior ligule is greatly elongated, conical and bears near the base of the dorsal cirrus an oblong oval lamella , at its ventral side a small rounded one; the dorsal cirrus projects somewhat beyond the tip of the ligule. The lip of the dorsal setige- rous lobe , enlarged and elongated in the same manner as the ligule, is provided at the base of its ventral side with a small oval lamella. The ventral lobe is cylindrically pro- duced and furnished with a large lamella, which is a little emarginated on the ventral side. The inferior ligule is about of the same length as the ventral lobe, faintly curved and provided with a conical process behind the middle of the supe- rior border. The ventral cirrus reaches nearly to the tip of the inferior ligule, bearing near its base on the dorsal side two small tongue-shaped lamellae and on the ventral side a large oblong oval one. Bristles with knife-shaped terminal pieces occur in both lobes of the feet. In some specimens the transverse paragnathi of group VI. show curious variations. For, whereas each paragnathe consists in its normal state of a long, narrow ridge, slightly notched in its middle, I found in one atocous specimen the left ridge broken up in four , the right one in three short transverse teeth ; in the middle between both rows a small conical tooth was situated , and behind the right row a large A-shaped tooth. The unpaired paragnathe of group V. has its normal situation. In examining the proboscis of the Notes from the Leyden Museum, Vol. XI. ANNELIDA POLYCHAETA. 167 large epitocous examples it becomes obvious, that by the lack of the chitinous investment the long ridges are broken up in some irregular pieces. It may be concluded from this case, how difficult it is to recognize the real arrangement of the paragnathi , when having only a single specimen at his disposal. Though these individuals show great resem- blance to N. Jloridana Ehl. l) and N. atlantica M'Int. 2) , I hesitated to identify them with one of those species. In N. jloridana the lateral patches of paragnathi in group III. seem to be absent, and the tentacular cirri are also much longer, reaching to the 11th segment; according to Lan- gerhans' description 3) , who examined this species at the coast of Madera, it should have »Gestalt und Vertheilung der Borsten" like in N. cultrifera, whereas in our speci- mens there occur no heterogomph setose bristles in the ventral lobe. N. atlantica also wants the lateral paragnathi of group III; moreover in this species the posterior feet seem to have the dorsal setigerous lobe (» second lobe" Mac Intosh) larger than the superior ligule (» superior lobe" Mac Intosh) , quite opposite to our specimens.

In the anterior body- region the lip of the dorsal setigerous lobe obtusely conical, longer than the lips of the ventral lobe , which measure about a third of its leugth. The ligules have the same shape as the dorsal lobe, the superior of them is a little longer, the inferior about of the same length. Dorsal cir- rus extending somewhat beyond the tip of the superior ligule, ventral cirrus reaching to the middle of the inferior ligule. In the anterior feet both cirri show a lamellar en- largement of their basal portion. In the inferior fascicle of the ventral lobe there occur, besides the heterogomph fal- cate bristles, a couple of heterogomph setose ones. In the feet of the middle body-region the lip of the dorsal lobe is considerably produced , with an oblong oval lamella at its base; the ventral lobe has a cordiform anterior lip and a large, round, lamellar posterior one. The superior ligule, extending a little beyond the tip of the dorsal lobe , bears near the base of the cirrus a rather large, oblong, oval lamella ; the inferior ligule , not reaching to the distal end of the ventral lobe , is furnished with a conical process near its base. The dorsal cirrus is longer than the superior ligule , smooth in the females , in the males provided with papillae on its distal half. The ventral cirrus longer than the inferior ligule, with an oblong, rhomboidal lamella near the base of its ventral border and two long, narrow, tongue-shaped lamellae at the dorsal edge. Bristles with knife-shaped terminal pieces of ordinary appea- rance occur in both lobes. The anal segment shows longitudinal grooves; the anal cirri as long as the posterior 10 segments.

Notes froru the Leyden Museum , "Vol. XI. ANNELIDA POLYCHAETA. 169 In a bottle containing Annelida, probably dredged with the tow-net in the Malayan Archipelago by Mr. Hoedt, I found several examples of this A^m's-species. Except one specimen they are all incomplete, the anal region being wanting or only partly regenerated. The males appear not to be smaller than the females. Almost all individuals are marked by two parallel, transverse, black stripes on the dorsum of the feet, most distiuct in the posterior body- region. The length of the tentacular cirri seems rather variable , for , in one specimen the longest of them reaches to the 5th segment, and in another one to the 8th ring. Though in the males the epitocous transformation of the feet commences at the 21st segment, we find already marks of it at the 20th segment, which shows small lamellae at the base of the dorsal and ventral cirri. In the females the change of the feet commences at the 23rd segment, but faint marks of it are already visible at the two preceding segments. There are also some differences between the feet of the anterior segments in the males and females. In this body-region the dorsal and ventral cirri are gibbous at the base, their distal end being very slender; in the males the anterior 7 feet show this character , in the females it is only observed at six of them. As in other Heteronereis-iorms the dorsal cirrus of the males in the posterior body-region is provided with papillae along its ventral border; but in the vicinity of the anal end this character disappears , as is already observed by Ehlers in epitocous examples of JV. Dumerilii. In our specimens this change occurs at the 60th segment; here the dorsal cirri have lost their papillae and show the appearance of those of the females. The dorsal cirri of this body-region show a curious abnormity in both sexes: they are in several segments considerably elongated and extend far beyond the tip of the superior ligule. This abnormal elongation of the dorsal cirrus occurs very irre- gularly , for often it is present at the left foot of a segment and wants at its right side. Such dorsal cirri of different length are also observed by Grube in some Sy Ms-species. Notes from the Leyden Museum, Vol. XI. 170 ANNELIDA POLYCHAETA. A considerable change in the shape of the feet may be observed in the posterior body-region , as not only the la- mellar processes gradually diminish in size, but also the setigerous lobes presenting different appearance. The dorsal lobe becomes broad and blunt, the ventral lobe on the con- trary is conically produced. The anal segment is without feet, cylindrical and its surface is longitudinally grooved; between these grooves there arise ridges of the skin, pro- vided along their border with papillae, which are greatly developed at the lateral sides of the segment. The ventral side of the anal segment is almost fully occupied by the base of the anal cirri. The regenerated anal segment has its surface beset with densely crowded papillae. In the maxillary region the dorsal side of the proboscis bears two paragnathi on the median line (I) , one large tooth in front succeeded by a smaller one, and on each side a small triangular patch (II) of 9 to 10 teeth is to be found; on the ventral side the median group (III) consists of a transverse patch of about 14 teeth and 2 or 3 teeth on each side, the lateral groups (IV) constitute a rather large semilunar patch of about 22 teeth. The basal region bears on the dorsal side a median triangular patch of 3 paragnathi (V), laterally a transverse ridge (VI) occurs , not very high , faintly notched in the middle ; in one specimen the middle por- tion of the left ridge is wanting , this tooth was thus broken up in two. On the ventral side a belt of three rows of teeth occurs, those of the median series alternating with the others ; in the median area two teeth are situated next each other. This species is closely related to N. taorica Laugh.1), N. Helleri Gr. 2) and N. camiguina Gr. 3). JV. Helleri however is distinguished by the length of its dorsal cirri, which are twice as long as the superior ligule. Our know- 1) Canarische Anneliden: Nova Acta der K. Leop. -Carol. -Deutschen Akad.

Notes from the Leyden Museum , Vol. XI. ANNELIDA POLYCHAËTA. 171 ledge of the characters of N. taorica is rather scanty, but this species seems to be characterized by having at the ventral side of the basal region of the proboscis only a single series of few paragnathi. Our species more nearly approaches N. camiguina , though the arrangement of its paragnathi is somewhat different , the structure of the feet is also somewhat doubtful, as we have no figure of them. Grube seems to have known only the atocous form, perhaps our specimens might be the epitocous form of this species. Nereis niyro-punctatti , n. sp. (PI. 8, figs. 1 — 3). Epitocous form. The body of the largest specimen measures 27 mm. in length; the number of its segments amounts to 70. Cephalic lobe trapezoidal, with the poste- rior margin truncated, not quite so long as broad; eyes large, situated next each other. Antennae having a third of the length of the head; palpi about twice as long as the antennae, their basal portion in the middle with an annular groove. The antero-posterior diameter of the buc- cal segment only slightly more than that of the succeed- ing ring; the inferior pair of the tentacular cirri about as long as the palpi, the longest of the superior pair reach- ing to the posterior border of the 4th segment or beyond. Segments in the anterior body- region on each side of the dorsum marked by a transverse blackish spot, posteriorly only with a dot of the same colour; head generally also marbled with blackish. The change of the feet commences in the males at the 16th segment, in the females at the 19th ring. At the feet of the anterior body-region the lip of the dorsal seti- gerous lobe has a rounded border, divided by a deep notch in a small superior and a larger inferior half; the ventral lobe is shorter, reaching about to the middle of the in- ferior edge of the dorsal lobe. The superior ligule is bluntly triangular, nearly of the same length as the dorsal lobe; the inferior ligule projects till the tip of the ventral lobe. Dorsal cirrus almost twice as long as the superior ligule, .Notes from the Leyden Museum, Vol. XI. 172 ANNELIDA POLYCHAETA. ventral cirrus of the same length as the inferior ligule. In the anterior feet the ventral and dorsal cirri greatly enlarged at their base. In the inferior fascicle of the ven- tral lobe sometimes a heterogomph setose bristle occurs. At the feet of the posterior body-region the lip of the dorsal lobe is conically produced , with a narrow oblong oval lamella at the base of the ventral border, the ven- tral lobe shows an obtuse , truncated anterior lip and a large lamellar posterior one. The superior ligule, about of the same length as the dorsal lobe , is provided at its dor- sal side with a small rounded lamella in front of the base of the dorsal cirrus, and with a rather elongated lamella behind it; the inferior ligule, projecting as far as the ven- tral lobe, has a large conical process near its base. Dorsal cirrus much longer than the superior ligule, smooth in the females , with eight papillae at the ventral side of their distal end in the males; ventral cirrus a little longer than the in- ferior ligule, on the dorsal side with two narrow tongue- shaped lamellae , on the ventral side with an oblong lamella near its base. Both lobes have setose bristles with knife-shaped terminal pieces of ordinary appearance. Anal segment with longitudinal grooves; anal cirri reaching as far as the pos- terior 6 segments.

In the same bottle , which contained N. malayana , I found more than hundred examples of this small, cha- racteristically marked species. Its body-length is very dif- ferent and varies from 27 to 12 mm.; nevertheless the small specimens are also in a state of sexual maturity and have about the same number of segments as the larger ones. The number of male and female specimens seems to be nearly equal. Notes from the Leyden Mummui. Vol. XI. ANNELIDA POLYCHAETA. 173 Like in the preceding species the length of the tenta- cular cirri seems to be very variable; for usually the lou- gest cirrus of the dorsal pair reaches to the 6th segment, however, in some individuals it extends only to the pos- terior border of the 4th ring , and in other ones it reaches the 9th segment. In the males the epitocous change of the feet commences at the 16th, in the females at the 19th ring; some segments, however, situated more in front , show already marks of this transformation , f. i. a small lamella at the base of the ventral cirrus at the 12th foot in a male. The dorsal and ventral cirri of the anterior feet have their basal portion greatly enlarged, in the males this is visible at the dorsal cirrus of the anterior 7 feet, but at the ventral cirrus of only 5 feet. The females show this character only at the dorsal and ventral cirri of the anterior 5 feet. The papillae occurring at the dorsal cir- rus of the posterior segments in the males, disappear nearly at the 50th segment; posteriorly the dorsal cirri are smooth as in the females. The maxillary region of the proboscis in most of the specimens has on the dorsal side a median (I) triangular group of 7 teeth ; this number however decreases in some of them to 4 , whereas in other individuals it increases to 9 or 11. Next to it on each side (II) there occurs a cur- ved group of 15 to 20 teeth. On the ventral side the median group (III) consists of three patches, a large transverse one of about 20 teeth , arranged in 4 series , and a small group ones however are not always quite isolated from the median of 2 to 4 teeth at a short distance on each side; the latter group. Laterally a large group (IV) occurs, consisting of 25 to 30 teeth. The basal region bears on the dorsal side (V) a median triangular patch of 3 paragnathi ; only in one of perhaps hundred specimens I observed 4 teeth in this group. Laterally (VI) a short, semilunar, ridge-shaped tooth occurs ; only in one specimen I observed behind the ridge of the right side another small transverse tooth. However sometimes one of both ridges is broken up in two Notes from the Leyclen Museum, "Vol. XI. 174 ANNELIDA POLYCHAETA. teeth. On the ventral side (VII and VIII) a belt of' two rows of teeth is to be found. From the foregoing description , based on the examina- tion of a great number of specimens, it may be concluded, that the arrangement of the paragnathi is very constant; the number of small teeth in the lateral groups varies within certain limits, but on the dorsal side the median maxillary group only appears to be liable to some varia- tion , as is already stated by other authors. Among the species of the Perinereis-d'ivision , characte- rized by having in group V. a triangular patch of three teeth , only a small number are described , which have in group I. more than 2 paragnathi ; they are : IV. perspicil- lata Gr. *), N. Anderssoni Kgb. 2) and N. exsul Kgb. 2). N. pei'spicillata , only known in atocous state, is distinguished from our species by the longitudinal series of paragnathi in group I , by the shortness of its palpi and by having the dorsal cirrus not longer than the superior ligule. Our knowledge of the characters of the two other species is too scanty. Nereis ferox Hans. (PI. 7, figs. 6 — 8). — Recherches sur les Annélides, recueillies par M.

Tentacular cirri short; the longest of the inferior pair about of the same length as the palpi , the longest of the superior pair projecting beyond the antennae , reversed they reach to the 5th seg- ment. The feet of the anterior and posterior body-re- gion show a different appearance. In the anterior feet, the lip of the dorsal setigerous lobe blunt, rounded; the lips of the ventral lobe only a little shorter , trapezoidal , with a slight notch. Superior ligule of the same shape and length as the dorsal lobe ; inferior ligule a little shorter , obtusely conical. The dorsal cirrus arises from a shallow notch of the superior ligule and is very long, projecting far beyond the tip of the dorsal lobe; the ventral cirrus only a little longer than the inferior ligule. In the poste- rior segments the superior ligule is considerably enlarged and consists of a broad lamella with a straight external margin and a convex internal one ; it bears on its tip the dorsal cirrus, which has only half its length. The dorsal lobe does not reach further than one fourth of the length of the ligule; the inferior ligule has undergone no change and has about the same length as the ventral cirrus. In the dorsal lobe only homogomph setose bristles; the ventral lobe contains : in the superior fascicle heterogomph falcate bristles and homogomph setose ones, in the inferior fascicle, besides the heterogomph falcate bristles, a couple of hete- rogomph setose bristles, at least in the posterior segments. Paragnathi of the proboscis: Maxillary region, I. one or two teeth ; II. small group of 3 or 4 curved rows ; IV. large group of 4 to 5 transverse series, and a semilunar patch in front of them; III. group of 3 or 4 transverse rows ; basal region , V. one conical tooth ; VI. transverse ridge; VII. and VIII. a belt of two series of teeth. The bottle contained only one complete specimen, be- sides some fragmentary examples, among which two ante- rior body-regions with proboscis. The worms are decolored, only the dorsum is partly brownish and marked with white transverse bands on the anterior margin of each ring. The Notes from the Leyden Museum , Vol. XI. '170 ANNELIDA POLYCHAETA. head is blackish , with a longitudinal white band in the median line, broad between the eyes and narrowing ante- riorly. The superior ligules, especially in the posterior bo- dy-region , show a greyish hue. The tentacular cirri of the different examples vary somewhat in length ; however in all of them the posterior of the right dorsal pair is the longest. The feet do not present the same appearance over the total length of the body , as stated by Hansen ; on the contrary the superior ligule, in the anterior segments only a little larger than the dorsal lobe , increases gradu- ally in the posterior body-region, and near the anal ex- tremity surpasses in size the total foot. However the dor- sal cirrus decreases gradually in length in the posterior region. The setose bristles are short and slender, of a vitreous appearance: those of the dorsal lobe do not project beyond the tip of the falcate bristles of the ventral lobe. However the falcate bristles are very stout, brownish; their termi- nal pieces are not »sans denticules" as stated by Hansen, but beset with fine setae along the base of the concave margin. Only in the posterior body-region the ventral lobe seems to contain , besides the falcate bristles , one or two heterogomph setose ones. Hansen's drawing of the probos- cis of this species is rather correct. The paragnathi show the characteristic appearance , by which , according to Kin- berg's description, his genus Paravereis should be distin- guished ; they consist for the greater part of pin-shaped teeth with darkbrown tip (papillae pectiniformes). Group I. consists of a single conical tooth , though in one spe- cimen I observed another smaller one situated more poste- riorly; in group II. there occurs a small patch of 3 to 4 succeeding transverse rows of pin-shaped paragnathi, of which the external row is the longest, group IV. consists of a large patch of 4 or 5 transverse rows of pin-shaped teeth , of which the external row is the longest and extends somewhat beyond the penultimate of them; between these and the maxillae another semilunar group of large conical JNotes from the Leyden Museum, Vol. XI. ANNELIDA POLYCHAETA. 477 teeth is situated ; group III. consists of 4 transverse series which are faintly curved in a knee-like manner , and of which the inferior one is the longest. The basal region has in group V. one bluntly conical tooth and in group VI. a transverse triangular ridge, whereas group VII. and VIII. show two series of teeth, alternating with each other; the posterior . series consists of longitudinal, narrow teeth (»dentes com- pressae" Kinberg), the anterior series of stout conical ones. Two specimens, described by Hansen under the name of N. obscura1), also belong to this species; the largest of them has the anal region complete, with two long anal cirri, extending about over the posterior 9 segments. The superior ligule of the feet preserves his great elongation till at the fifth segment in front of the anal end , poste- riorly it decreases gradually in size. Another specimen , labelled N. coerulea Hans. 2) , ought to be ranged also under this species ; though it wants the anterior body-region , the structure of its posterior feet is characteristic enough to recognize the species at once. The drawing of one of the anterior feet (PI. IV, fig. 1) rather well resembles our fig. 6. Hansen's statement , that the terminal pieces of the falcate bristles are devoid of setae , is not correct. Another specimen , labelled N. microphthalma 3) , must also be identified with this species; on comparing Han- sen's drawing of a foot on PI. IV, fig. 26, with his figure 1 , I cannot find out much difference. The specimen has the dorsum of the anterior body-region reddish coloured; the head shows the ordinary white longitudinal band , and each segment is marked on the lateral sides of the dor- sum with some white oblique lines, extending from the posterior margin of the segments to the middle. In exa- mining the proboscis , I found in group I. three paragnathi , 1) loc. cit. p. 13, pi. IV, figs. 18—24. 2) loc. cit. p. 11, pi. Ill, fig. 31, and pi. IV, figs. 1—3. 3) loc. cit. p. 13, pi.

This species is closely allied to N variegata Gr. *), per- haps identical with this species from the West-coast of South America (Callao and Valparaiso); as the descrip- tion of this worm is not accompanied by figures , the ques- tion remains somewhat doubtful. However in his paper» die Familie der Lycoriden" published afterwards, Grube gives more detailed communications about the arrangement of the paragnathi and states that the species shows all the stri- king characters of Kinberg's genus Paranereis. N. ferox resembles N. variegata 2) as well in the colour and the dimensions of the cephalic lobe, as in the length of the tentacular cirri and the structure of the feet.

In our collections there are two large A^rm-specimens , collected by Mr. Horstock at the Cape of Good Hope , which I believe must be identified with Grube's N. Stimp- sonis. However some confusion seems to reign in the de- scription of the characters of this species. For Grube's description is established on two specimens: a large one collected near the Cape during the Cruise of the Novara, and another example of the Hamburg Museum probably from the same locality; because this latest specimen much agreed with Ar. variegata (really belonged to that species, as I believe) , therefore Grube concluded that his N. Stimp- sonis should be considered to be a variety of N. variegata. 1) Annulata Oerstediana, Naturh. Foren. Vidensk. Meddedelser, 1857, p. 7. 2) About Grube's identification of N. variegata and TV. Stimpsonis see fur- ther on. ^Notes from the Leyden Museum , Vol. XI. ANNELIDA POLYCHAETA. 179 Though it is very difficult to settle this question without examining the type-specimens , it appears to me that Grube's description probably is based on two different species ; other- wise I cannot clear up the controversies in his descrip- tions. In N. Stimpsonis the cephalic lobe should have the same length as the buccal segment, in N. variegata on the contrary it should be a little longer than the two fol- lowing segments. In his paper» die Familie der Lycoriden", on p. 16, Grube mentions N. Stimpsonis and N. variegata as two different species , and in speaking of the structure of the paragnathi (» papillae compressae" and » papillae pectiniformes") , he only refers to N. variegata , not to N, Stimpsonis. Therefore I believe it will be not without interest to give a detailed description of our specimens. The largest individual is a female , in state of sexual maturity; it measures 125 mm. in length and 11 mm. in breadth at its widest part (with the feet). The number of its segments amounts to 91. The cephalic lobe is a little longer than the anteropos- terior diameter of the buccal segment. The antennae are short , scarcely half as long as the head , extending till the first articulation of the palpi. The tentacular cirri are not long, not projecting beyond the tip of the antennae, and reversed they reach till on the middle of the 2nd segment. The antero-posterior diameter of the buccal segment one third longer than that of the following ring. The feet of the anterior and the posterior body-region considerably different in structure. In the anterior segments the dorsal setigerous lobe short , rounded , papilliform , the ventral lobe shorter, trapezoidal. The superior ligule of the same shape and size as the dorsal lobe , the inferior ligule a little shorter than the ventral lobe, obtusely conical. The dorsal cirrus blunt and stout, projecting far beyond the tip of the dorsal lobe, about twice the length of the superior ligule ; the ventral cirrus on the contrary much shorter than the ventral lobe. In the posterior segments the superior r^otes from the Leyden Museum, Vol. XI. 180 ANNELIDA POLYCIUETA. ligule is greatly enlarged , and consists of an elongated lamella; the inferior ligule is obtusely conical, longer than the ventral lobe , about of the same dimension as the dorsal one. The dorsal cirrus , arising from a shallow notch of the ligule, measures a little more than one third of its length. The ventral cirrus is much shorter than the inferior ligule. The paragnathi consist only of blunt, conical teeth. The maxillary region of the proboscis has in group I. one tooth ; II. is a narrow semilunar patch ; IV. is a larger group of about 5 transverse rows ; III. a transverse patch of 3 rows; basal region, group V. one conical tooth ; VI. a large, oval, transverse ridge; VII. and VIII. an irregular belt of four series, uniting into a single one at the dor- sal side, the anterior teeth of the belt are the largest. In regard to this character our specimens differ from Grube's N. Stimpsonis , which has a belt of only two series. In Grube's drawing of the proboscis (fig. 8, a) the groups V. and VI. seem to consist of minute teeth; however this must be a mistake of the artist, for Grube states exactly: »annulus posterior supra granis 3 maximis valde distentis, triangu- lum valde obtusangulum vel lineam componentibus". More- over in his paper »die Familie der Lycoriden", p. 16, he observes, that his N. Stimpsonis belongs to the sub-genus Perinereis. Ehlers seems to have overlooked this , for in his systematical table N. Stimpsonis is erroneously ranged in the group characterized » Kieferspitzen vollst'andig, nur kegelförmige". Wereis minor Hans.

In the posterior segments the superior ligule is enlarged and presents a more acute shape; the lip of the dorsal lobe is more conical, about of the same appearance as the inferior ligule. The ventral lobe presents a narrow lamella. The ventral cirrus , about of the same length as the inferior ligule, bears near its base on the dorsal side two obtuse, tongue-shaped lamellae , on the ventral side a narrow rounded lamella. The inferior fascicle of the ventral lobe contains , besides the heterogomph fal- cate bristles , a single heterogomph setose one. Paragnathi of the proboscis : Maxillary region , I. two teeth situated behind each other; II. small, semilunar group; IV. large curved patch; III. transverse group ; basal region , V. triangular group of 3 teeth ; VI. a transverse , round ridge ; VII. and VIII. a belt of two rows of conical teeth , alternating with each other ; on the ventral side the rows are separated from each other , on the dorsal side they unite in a single series. The bottle contained only a single incomplete specimen , wanting the posterior body-region. It is a female with completely developed eggs, presenting however only faint marks of epitocous transformation. The eyes are not en- larged; the feet of the posterior segments present but some faint lamellar processes, and bristles with knife-shaped ter- minal pieces could not be observed. Already several species of the PmWm's-group are known , which have in group V. of the proboscis a triangular Notes from the Leyden Museum , Vol. XJL. 182 ANNELIDA POLYCHAETA. patch of three paragnathi ; among them JSr. Anderssoni belongs, found in the same locality as our specimens (Rio de Janeiro). That species seems to be distinguished from N. minor , by having in group I. of the proboscis not 2 , but 4 paragnathi , however because the number of para- gnathi in group I. is liable to some variation in the same species, perhaps both species may prove to be identical. In the following table I have tried to enumerate all the known species of Nereis , which belong to the Perinereis- group ; the literature on Annelida being however so exten- sive and dispersed in so many periodicals, which are often very difficult to be get, one or another species may have been overlooked. Nevertheless I hope, that my colleagues, dealing with this matter, will not find it quite useless. Perinereis. A. Transverse and conical paragnathi in group VI. Marionii Aud. et Edw.

Therefore I believe that in N. atlantica the two horny ridges are situated in group VI. and the small tooth in V, as in other species of Perinereis; should this not be the case, the species could not at all belong to Kinberg's Perinereis, as supposed by M'Intosh.

Notes from the Leyden Museum, "Vol. XI. HELOTA BOYSII. 189 NOTE XXXVI. ON AN UNBESCRIBED SPECIES OF THE COLEOPTEROUS GENUS HELOTA, MACLEAY. BY C. RITSEMA Cz. To the liberality of Prof. Westwood I owe the oppor- tunity of adding a new species of Helota to the number already described , and as the specimen communicated to me (a cT) is labelled » Helota Boysii Westw." , I believe it desirable to maintain this name. Helota Boysii is a very narrow and elongate species, and closely allied to H. pusilla R. Oberth. l) and culta Olliff 2) of which I have the types before me. It is, however, considerably lar- ger, measuring 9 mm. in length, which gives it some re- semblance to H. laevigata R. Oberth. 3). The latter, how- ever, is broader, has a shorter thorax and otherwise coloured antennae, sides of prosternum , elytral epipleurae 4) and legs, and its tibiae are considerably more elongated. More- over the tibiae of the anterior pair of legs in the males are quite differently shaped : in laevigata cf they are more elongated (as is already said), and distinctly curved about the middle; in Boysii cf on the contrary they are shorter and stouter, slightly curved at the apex on the out- side, and provided at the apex on the inside with a flat- tened and truncate black appendage which is directed for- 1) Coleopt.

Finally the pubescence of the basal joints of the anterior tarsi is much longer and denser in Boysii (ƒ than in the same sex of laevigata. From pusilla (the male sex of which is unknown to me) the new species differs, besides by the sexual characters and by its larger size (9 mm.) , by the pale colour of the club of the antennae , by the punctuation of the head which is considerably coarser and denser, by the shape and punc- tuation of the prothorax (in Boysii the prothorax is pro- portionately longer, more strongly narrowed in straight lines to the front and consequently of a regular trapezoidal shape , with broadly rounded anterior angles which are not at all produced ; the punctures on the pronotum are larger , more widely and irregularly spread , leaving free a longi- tudinal streak in front of the scutellum ; as for the punc- tuation of the pronotum it agrees therefore better with laevigata than with pusilla). Moreover, H. Boysii differs from pusilla in the position of the yellow elytral spots: in the former the anterior as well as the posterior spot is placed between the 3rd and 7th striae, whereas in the latter the anterior spot is placed between the 4th and 7th, the posterior one between the 3rd and 7th striae. Finally in Boysii the metallic green colour on the tibiae is restricted to the basal fourth , whereas in pusilla it occupies slightly more than the basal half. From culta tf it may be distinguished by its superior size , straight (not constricted) sides of the prothorax , flat- tened appendage at the apex of the anterior tibiae, more narrowly rounded apices to the elytra which show a mi- nute sutural tooth, proportionately smaller elytral spots, etc. In both species the 5th ventral segment has no im- pression , and the hinder-margin is truncate , more nar- rowly , however , in culta than in Boysii. The examined male specimen comes from India (Boys) and belongs to the University Museum at Oxford. Notes from the Leyden Museum , Vol. XI PORPHYRIO BEMMELENI. 191 NOTE XXXVII. ON A NEW SPECIES OF GALLINULE. BY J. BÜTTIKOPER. Some days ago our Museum received a probably fully adult female of Porphyrio , kiudly sent by Mr. A. A. van Bemmelen, the able Director of the Zoological Garden at Rotterdam , with the assurance , that the bird had been caught at and sent from the Lake Toba in the Interior of Sumatra. Peculiarly enough there is hitherto no evidence published as to the occurrence of a Porphyrio in Sumatra , except by Cassin in U. S. Exploring Expedition , Ornith. p. 308 , where, treating of P. indicus , the author says that the Museum of the Philadelphia Academy contains specimens from Java , Sumatra and other islands of the Malay Ar- chipelago. As Porphyrio indicus Horsf. (P. calvus Vieill.) has also been found in Borneo , I was much astonished to see that our Sumatran bird differs not only from this, but also from both the known species from the Continent, though those latter may be considered to be its nearest allies. According to Elliot's Monograph of the genus Porphyrio (Stray Feathers, 1878, p. 6), the Gallinules from the Con- tinent belong to two gray-headed species; P. poliocephalus (Lath.) = P. neglectus Schl. , inhabiting Ceylon and India from the Bay of Bengal to Tenasserim, and P. edwardsi Ell. from Cochin-China. Although very closely allied to both above mentioned species , especially to the second , our Sumatran bird dif- Notes from the Ijeyden Museum, Vol. XI. 192 PORPHYRIO BEMMELENT. fers from both by the blue (instead of purplish) color of sides of chest, breast and flanks, and from the latter spe- cies , with which it is related by its dark green color of back and wings, by the sea-green instead of turquoise blue color of the lower throat and chest. The new species , which I propose to call after Mr. van Bemmelen , who rendered already so many important ser- vices to Ornithology , may be described as follows : Porphyrio bemmelen i. Head , chin and upper throat gray , sides of head tinged with blue, ear-coverts and occiput with a purplish hue, sides of neck and hind neck purplish ; entire back , rump, upper tail-coverts, secondaries and greater wing-coverts dark green, the latter strongly tinged with olivaceous and nar- row undulations under certain lights; mantle, scapulars and lesser wing-coverts paler green, also undulated and more or less broadly margined and tipped with blue. Quills blackish on the inner , green on the outer web ; edge of wing, under wing-coverts, lower throat and chest, pale green; sides of chest, entire breast and flanks pale (not purplish) blue; abdomen and vent somewhat darker blue, uuder tail-coverts pure white, thighs dark green like the back. The tail-feathers are mutilated is our specimen. Bill, head- shield , legs and feet red , with the exception of the knees and joints of toes , which are black ; iris red.

NEW SPECIES OF AFRICAN COLEOPTERA (CARABIM) IN THE LEYDEN MUSEUM. H. W. BATES, F. R. S., F. L. S. The following are descriptions of' what appear to be new species (including one new genus) in a collection of African Carabidas submitted to me by Mr. C. Ritsema for examination.

S^/., millim. Humpata (Veth & van der Keilen). — One example. The species is very distinct from the widely distributed L. (Astata) tetragramma and is distinguished not only by the different shape and position of the anterior spot of the elytra , but by the narrower thorax , much more coarsely vermiculate-rugose on the surface and black with rather well defined reddish-yellow lateral borders, and by the more strongly striated elytra. Judging from a single example from Lagos which I have compared , the L. bisbinotata (Murray) differs from the L. tetragramma of Natal only in the external angles of the elytra being more produced and acute.

Nigra parum nitida, thorace imma- culato , elytris valde convexis elongato-ovatis , interstitiisque valde convexis , margine lata humeros attingeuti maculaque humerali contigua (apud interstitia 6 — 7) albo-pubescentibus. — Long. 35 millim. tf. Mossamedes (Sala). A single male example, of minor development. The head has only a few minute punctures and the thorax has precisely the same form as in corresponding individuals of A. omostigma ; but the elytra are much more convex and shorter with the Notes from the Leyden Museum, Vol. XI. AFRICAN CARAB1DAE. 203 sides more rounded, so that their form is ovate and not in the least oblong-quadrate. The white tomentose border covers the two marginal interstices and behind reaches the suture; it also nearly reaches the base and at its termina- tion is separated from the humeral spot only by the extre- mely narrow carina into which the 7th interstice is here contracted. The description of A. Actceon (Erichs.) also from Ben- guella , agrees very nearly with A. ooptera , but no men- tion is made of the white humeral spot, and besides the »interstitiis leviter convexis" and » striis postice evanescen- tibus" do not at all fit but suit almost exactly examples of A. cinctipennis (Lequien) which I have examined from Lake Ngami and Damaraland.

A male from Humpata (Veth & v. d. Keilen), and a female from Mossamedes (Sala). Extremely near A. omostigma from Benguella; differing only in the absence of the white pubescent humeral spot and in the stronger convexity of the elytra at the base and shoulders ; the elytra although equally elongated are espe- JS"otes from the Leyden Museum , Vol. XI. 204 AFRICAN CARABIDAE. cially in the <ƒ narrower and more ovate. Males of minor development of the two forms agree exactly iu the form of the thorax; examples of A. niveicincta of higher develop- ment I have not seen ; in A. omostigma they differ in the lobe of the thorax being much prolonged , dilated and flat- tened out behind with the exterior angles produced and acute. A similar difference in thoracic structure is present- ed in the males of all the allied species. N etr o der a V e t h i, nov. spec.

Q. Benguella (Veth & v. d. Keilen). — A single example. Belongs undoubtedly to the genus Nestra (Chaud.) which I agree with Perroud in considering quite distinct from Atractonotus , so that if the latter is to be separated from Polyhirma , so must the former. Its more obvious points of distinction are the shorter semi-ovate prolongation of the head behind the eyes and the tricarinate elytra. Poly- hirma Baucis (Dohrn) from the description must belong to Atractonotus and is probably hardly distinct from A. Mul- santi (Perroud). Aulacillus, nov. gen. (Subfam. Scaritinse). Apterus.

Abdominis segmenta 3 — 5 basi transversim sulculata, 2 — 6 foveolata. The obtuse aud wholly unarmed apex of the maxillae and dentate sides of the thorax bring this genus into the neigh- bourhood of Haplogaster and allies , but it has certainly a close affinity with Tamiolobus , with which genus it is con- nected by several Tropical African species having, like Tceniolobus, the maxillas produced at their inner apex, but with the deeply bisulcate forehead and facies of Aulacillus. In the rather long and robust claw-joints and claws it indicates also an affinity with the very different-looking genus Ochyropus. Aulacillus Liberianus, nov. spec.

The species is distinguished from its nearest ally, S. stri- atocollis, at first sight by its elongate-oblong and unicolo- rous elytra; but it differs in the narrower and much more convex lateral and apical interstices and in the wider and deeper marginal groove of the thorax. In the anterior tarsi of the 9 tue 1st and 2nd joints have their inner apices sharply produced but scarcely spiniform and the external edge of the anterior tibiae is unarmed in both sexes though having a few short spines on their lower surface.

(Plate 9, figs. 1, 2, 3, 4). A closer study of the Bat exhibited in my » Catalogue systématique des Mauiraifères, 1888, p. 158" as variété insulaire of Eonycteris spelaea forces me to separate it from the named species and to regard it as a new spe- cies belonging to a genus very different from all the hi- therto described genera in the Macroglossine-group. Its index-finger is without a claw like in Eonycteris, Ne- sonycteris and Notopteris. It differs from Notopteris by a much shorter tail , by its dentition and by having the wings not from the central line of the back ; it differs from Eonycteris by having the wing-membrane attached to the second toe (not to the first) and by its dentition ; it differs from Nesonycteris by having a well developed tail and another dentition. The following description will show the more differences between the named three genera and my new genus C a I liny et e r i s , g. n. Muzzle long, narrow, cylindrical; nostrils not projecting; upperlip with a vertical groove dividing the nostrils; lower lip grooved in front. Tongue very long and attenuated.

Wings separated by a rather considerable interval from the spine of the back ; wing-membrane from the base of the second toe. Tail well developed , for one third contained in the membrane. Dentition: I. |, C. J-=-J, P.jg, M.g = 32. Callinycteris rosenbergii, n. sp. Ears much longer than the muzzle, oval, rounded off above, with several folds. Body above and below clothed with densely set pale brown and very soft hairs. The fur of the head extends upon the face as far as the naked nostrils. Muzzle with longer hairs , among which some black ones , thinly spread between the other shorter fur. Wing-membranes brownish black. As in Eonycteris there are placed on each side of the anal opening two small, cutaneous, kidney-shaped, gland- like bodies. In Eonycteris these bodies are placed a little behind the anal opening, meanwhile in Callinycteris the anal opening is exactly in the middle between the named bodies. Tongue in the middle of its surface thickly covered with recurved papillae; for the rest the tongue is covered with smaller papillae overlapping its margins. Palate-ridges seven in number, the three posterior ones divided in the centre. Upper incisors very small , equidistant from each other and from the canines ; first upper premolar very small , equidistant from and close to the canine and the second premolar. Second upper premolar triangular , about two fifth of the canine in height. Upper molars crowded , with- out interval between the second premolar and the first molar ; first and second molars with a longitudinal furrow ; hindmost molar about half the diameter of its predeces- sor and scarcely raised above the level of the gum. Lower incisors in a triangular series; lower canines about Notes from tlie Leyclen Museum, "Vol. XI. CALLINYCTERIS ROSENBERG II. 211 two thirds of the upper canines in height. First lower pre- molar half the height of the second , close to the canine and separated by an interval from the first molar , which is separated from the second premolar by an interval of the same dimension ; second and third molars scarcely raised above the level of the gum; a very small interval between the three molars; third molar about half the diameter of the second one. The dental-formulae in the genera hitherto known as belonging to the Macroglossine-group are the following: Macroglossus: I. f, C. j, P. |, M. 4 x 2 = 34. Eonycteris: I. -f-, C.

BY Dr. F. A. JENTINK. August L889. I have to add a new species to the series of Shrews discussed and described by me in the Notes from the Ley- den Museum, 1888, p. 161, and I previously named it Pachyura semmelinki in my Catalogue systématique des Mammifères, 1888, p. 257. I now proceed to describe it as follows. Pachyura semmelinki, n. sp. Fur rather long for a Shrew; the base of the hairs mouse-color, the hairs of head and upperparts of body tipped with maroon , those of the belly with light brown. Hairs of hands , feet and tail maroon. Tail conical, very hairy so that the scales are hardly visible; elongated hairs are widely set along the whole tail. Muzzle swollen. Upper jaw: posterior hook of first incisor as high as the fourth tooth; this latter is unicuspidate and is about four fifth of the size attained by the second also unicus- pidate tooth; third unicuspidate and about two thirds of the fourth ; fifth unicuspidate very small and hardly visible from without. Lower jaw: first incisor with a small denticulation ; se- cond unicuspidate and about two thirds of the height of the third unicuspidate which attains the height of the posterior cusp of the first molar. All the teeth are white. Notes from the JLieyden Museum , "Vol. XI. 214 PACHYURA SEMMELINKI. Measurements of the type-speciinen , an adult female, preserved in alcohol: mm.

SOME OBSERVATIONS RELATING TWO SEMNOPITHECUS-SPECIES EROM THE MALAYAN ARCHIPELAGO. Dr. F. A. JENTINK. September 1889. (Plate 9, figs. 5, 6, 7). The well known scientific investigator of North-East- Sumatra , Dr. B. Hagen , presented some weeks ago to our national Museum two skins belonging to two diffe- rent Semnopithecus-sipecies from Deli , in consequence of which 1 was obliged to enter into the labyrinth of syno- nymes of the very entangled Semnopithecus-gvouip. The fol- lowing lines contain some conclusions. Semnopithecus fem oralis Horsfield. One of the specimens agrees exactly with the specimens collected by the late Horner on Mount Ophir, West-Cen- tral-Sumatra, and since in our Museum. The species has been described and figured in the » Verhandelingen, 1839 — 44, p. 73, Tab. 10 bis" under the name of Semnopithecus Sumatranus. » Although specifically separated from S. »chriisomelas'\ the author remarked, 1. c. p. 73, »S. Suma- »tranus is by its general appearance and by its color so » closely allied to S. chrysomelas that it perhaps ought to »be considered as a local variety of that species." In 1876 Schlegel (Catalogue, Simiae , p. 45) rejected the specific title Sumatranus in favour of the name given for- Notes from the Leyclen Museum, Vol. XI. 'il O SEMNOPITHECUS FEMORALIS. merly by Horsfield, scilicet S. femoralis , but maintained the specific distinction of S. chrysomelas. Anderson (Yunnan Expedition, 1878, p. 31) being ig- norant of Schlegel's » Catalogue," as he nowhere quoted it in his book , asserted : » as has been pointed out by pre- vious authors, there do not appear to be any facts re- flating to the structure of the so-called S. chrysomelas »frora Borneo that would sanction its recognition as a » species distinct from S. femoralis of Sumatra, and I have » arrived at this opinion after an examination of the type » specimens." Oldfield Thomas (P. Z. S. L. 1886, p. 66) seems to differ from Anderson, for he states that »the few localities as »yet recorded for S. femoralis Horsfield are all either in »the South of the Malay Peninsula or in Sumatra." It is clear that Oldfield Thomas keeps S. chrysomelas distinct from S. femoralis, otherwise he would have added Borneo to the above given localities. Blanford (The fauna of British India, 1888, Part I, p. 42) agrees, as it seems, more with Anderson, for he says that S. femoralis is distributed over Borneo , Sumatra and the Malay Peninsula, extending north into Tenasserim. Having now given an exposition as short as possible of the stand of the question I will proceed to give my opinion in a few words. I confess that it is very difficult to ob- serve striking differences between S. femoralis and S. chry- somelas as to their external appearance, but I think that only a careful study of their skulls will settle the question. In comparing adult skulls . of S. femoralis with the dra- wings in the » Verhandelingen , plate 11, fig. 3," I am unable to find difference whatsoever, but in comparing the same bony parts of young specimens of the two species , I suppose that there are to be observed very striking dif- ferences. As I have no young skulls of S. chrysomelas to compare with the young ones of S. femoralis in our col- lection , I at present can only state that the peculiar form of the frontalia and parietalia in our young skulls of & Notes from tlie Leyden Museum , Vol. XI. SEMNOPITIIECUS FEMORALIS. 217 femoralis hardly can be explained by difference in age alone ; so that in my opinion we will do correct to accept , at all events previously, Schlegel's views and call the Bor- neo-form S. chrysomelas. I remark that the skull of S. chrysomelas, drawn by Schlegel in the » Verhandelingen" is not to be found in our Museum and that I wrongly said in my » Catalogue ostéologique" that skull b was there figured. The two skulls mentioned in my » Catalogue" are fullgrown but not so adult as Schlegel's figures indicate, the canines being much less developed in our specimens. Semnopithecus maurus auctorum. The second above mentioned Semnopithecus is a beautiful specimen belonging to the form described by Desmarest as S. pruinosus. Although Schlegel is quite right in his sta- tement that the name given by Desmarest is more appro- priate than the specific title bestowed upon it by Raffles, viz. cristatus, I think we should be forced to use Raffles' name, as having the priority of date and the more as being accompanied by a very excellent description. Schlegel wrote (Catalogue, Simiae , p. 58): »cette espèce ressemble »sous tous les rapports au S. maurus, a cette exception »près qu'elle a tous les poils du pelage plus ou moins lar- »gement terminés de gris blanchatre. Elle remplace le «S. » maurus a Sumatra, Borneo et dans l'ïle de Bangka." Anderson (Yunnan Expedition, p. 30) wrote: »in the size »and proportions of its parts S. cristatus closely resembles »S. maurus, and many zoologists have considered it merely »as a local race of that form, an opinion justifiable from »the mere consideration of their external characters, but »it remains to be ascertained whether these views are sup- » ported by the structure of their skeletons." Now the skull of S. pruinosus (cf. plate 9, figs. 5, 6 and 7, drawn after the skull of Hagen's specimen) agrees in all details so exactly with the same bony parts of S. maurus that I cannot see any important difference and as the external characters of both forms are so very inconstant Notes from the Leyden Museum , "Vol. XI . 218 SEMNOPITHECUS MAURUS. and changeable I do not hesitate in considering the Su- matra-Bangka-Borneo-form as belonging to the same species as the Java-form , and as Schreber's specific title has the priority of about half a century over Raffles', we are obliged to call the species Semnopithecus maurus Schreber. In accepting this name it must however be observed, that Schreber never has described a monkey under the men- tioned specific title : he figured Tab. XXII , B , a young monkey under the name Simla maura, but called it in the text: »Der Mohraffe." As synonyme he cited Simiolus cei- lonicus Seba, Thes. I, p. 77, tab. 48, fig. 3; Schreber adds »der Geburtsort dieser Gattung ist nach Seba Zeilan , nach »Herrn Edwards Guinea." If Schreber was right in uniting his Simia maura with Seba's Simiolus ceilonicus , then Seba's name ought to be given to the species in question , as Seba's book is from the year 1734, meanwhile Schreber's Saugethiere dates from 1775! But I think it need not to make more conjectures as my intention was merely to ex- hibit the specific similarity of Semnopithecus pruinosus Des- marest (Semnopithecus cristatus Raffles) with Semnopithecus maurus auctorum.

Habitat N. E. Borneo. — In mus. nostro. Head ochraceous, with the tip of the mandibles piceous and the throat black; coarsely punctate in front, strongly rugosely punctured on the vertex, the inter-antennary ridge divided by a deeply impressed median line. Antennae ochraceous with the five apical joints black, the base of the first black joint somewhat clearer, but on the other Notes from the Leyden Museum, Vol. XI. 220 PACHYTERIA AP1CALIS. hand the extreme tip of the last ochraceous joint slightly infuscate. The scape is rather deeply punctured above, almost smooth below ; the 3rd joint is not quite as long as the two next following joints together, this joint as well as the 4th is provided with a sparse fringe of fulvous hairs along the underside. Prothorax very broad and relatively short, strongly transversely sulcated and narrowed anteriorly in a neck- like manner and abruptly depressed and constricted pos- teriorly. The posterior margin slightly turned upwards; the sides distinctly but not sharply toothed and obliquely narrowing in nearly straight lines from the spines to the constricted front part. Both , the constricted anterior and posterior portion , metallic purplish black , thickly covered with short stiff black hairs , the rest ochraceous and clo- thed in the middle with a short somewhat silvery shining pile. The disc shows a broad but shallow impression in the centre and on each side there is an other broad shallow groove, originating near the lateral spine and obliquely turning upwards. Between these lateral grooves the disc is strongly rugosely punctured , whilst the parts outside of the grooves are very thickly and finely punctate, and, being moreover destitute of the silvery pile , they have consequently a much more opaque appearance. The black parts are also finely but not so closely punctured. Scutellum purplish black, elo ngate- triangular , sharply pointed and delicately punctured. Elytra ochraceous with the greater apical third bluish black, brighter towards the apex; entirely clothed with a' dense short brilliant silvery pubescence. From the base towards the top the elytra are gradually narrowed , their apices conjointly rounded; strongly and thickly punctured all over , the sculpture but very slightly decreasing towards the apex, moreover each wing-case presents two faintly elevated longitudinal lines. Underneath bluish black, with the sides and the middle of the prosternum ochraceous and a small ill-defined ful- ISTotes from the Leyden Museum, Vol. XI. PACHYTERIA APICALIS. 221 vous spot on the metasternal episterna. Legs ochraceous, the femora and coxae darker, somewhat brownish and with very faint purplish tinges under certain lights. The sides of the prosternum densely and finely punctate , the punctures becoming gradually larger and more distant near the middle. The breast is covered with extremely fine and closely set punctures, which are intermixed with a few large and deep ones; clothed with a delicate silvery pu- bescence. The abdomen with some large distant punctures, which are somewhat more numerous on the last ventral segments; the 5th segment is very deeply semicircularly emarginate , the 6th segment more broadly so ; the hinder- margin of the 1st segment is clothed with a rather broad band of silvery pile , whilst on the two following segments a similar but narrower band is broadly interrupted in the middle. Legs slender , the hinder femora almost reaching the apex of the elytra, thighs and shins rather coarsely punctured, the sculpture of the former closest near the knees; tibiae fringed with fulvous hairs at the innerside. This species is most nearly allied to P. ochracea C. 0. Waterh., but clearly distinct by the different coloration of the elytra and antennae. The structure of the prothorax is also quite different.

ADDITIONAL REMARKS ON DOLICHOPROSOPIS MACULATUS, RITS. J. R. H. NEERVOORT van de POLL. The description of the above named Longicorn has been drawn up from a unique, rather old 9 specimen in the collection of the Leyden Museum , originating from Hal- maheira. I possessed already for some time a fine V exam- ple from the same locality , which agrees exactly with the type specimen , however , being quite fresh , the rufous co- lour of the elytra is much darker and the elytral spots are chalky-white not dirty-white. More recently I got a cf specimen from Batjan, which in general appearance recedes so largely from the typical form , that it might be easily mistaken for a distinct species. The elytra, instead of being rufous-brown , are entirely clothed with a pale bluish-grey pile , on this ground colour the chalky-white spots are still perfectly contrasting. I failed to find this colour-difference accompanied by any structural character, of course besides the sexual peculiarities of the longer antennae and the thicker scape. Such an important change in colour of the covering pile is not to be met with abun- dantly and it remains to be elucidated whether this variety must be regarded as a geographical form peculiar to Batjan , or simply as a sexual peculiarity 1). Under these circum- stances I abstain from proposing now a name for it, which it surely deserves , if it turns out to be a local form. 1) The possibility of its being a sexual difference is not excluded , I may ca to mind the enormous differences existing between the sexes of many species o i Dorcadion. Notes from the Leyden Museum , Vol. XI. GYMNETIS KERREMANSI. 223 NOTE XLV. REMARKS ON GYMNETIS KERREMANSI, V. D. POLL. BY J. R. H. NEERVOORT van de POLL. (Plate 10, fig. 5). In volume VIII (p. 231) of the » Notes", I have des- cribed a Cetonid from Panama , under the name of Gi/m- netis Kerremansi. This species belongs to the Central- American fauna and of course Mr. Bates has had to deal with it in the »Biologia Centrali- Americana". As I had recently the pleasure of visiting my distinguished friend , he told me that my G. Kerremansi had given him much trouble and that he was not at all sure , the species he had mentioned and figured in the above quoted work, was really referable to my Kerremansi. In as much as I could judge from memory, the specimens he showed me did not agree with my species , but not having looked at my Gymnetis for several months, I would not risk a de- cided opinion. However, I promised Mr. Bates to study the question as soon as I should be back at home, in order to make it possible to insert eventual corrections in the Supplement of the Scarabaeidae of Messrs Godman and Salvin's work. Now , after having carefully studied and compared my insect and description with the figures and remarks pu- blished by Mr. Bates , I have not the least hesitation in considering my G. Kerremansi perfectly distinct. It is evi- dent that Mr. Bates has endeavoured to make my descrip- tion fit for the species that had come under his notice, Notes from the Leyden Museum , Vol. XI. 224 GYMNETIS KERREMANSI. therefore my terms »cervina" and » fallow" had to mean bluish-grey , therefore no attention has been paid to the coloration of the elytra, which is very characteristic, each elytron having in the middle a pale yellow large oval spot surrounded by a mixture of ochraceous rufous-brown and black , the latter colour even predominates. The gla- brous parts of the underside and the legs , I described as brilliant black with a strong purple-bronze hue, which is also in contradiction with the figure in the Biologia , where legs of a greenish colour are represented. I have added to these few words of friendly protest a very satisfactory figure of G. Kerremansiy which certainly will assist to remove all doubts better than a long de- scription would be able to do. As to the species figured by Mr. Bates , I think to make no mistake in supposing that it will prove to be referable to G. Wollastonii Schaum (Trans. Ent. Soc, London. V (1848), p. 66; pi. 8, fig. 3), a Mexican species not recorded in the „Biologia". Rectification. According to a lapsus calami, I have com- pared Moscheuma sebosum v. d. Poll (described in the same paper as Gymnetis Kerremansi) , at the end of the descrip- tion with M. costatum Oliv. , a species which does not exist. Olivier's well-known species has been described un- der the name of Cetonia lobata. Amsterdam, July 1889. Notes from the Leytlen Museum, Vol XI ODONTOLABIS 1NTERMEDIUS. 225 NOTE XL VI. ON A NEW SPECIES OF THE LUCANOID GENUS ODONTOLABIS, HOPE. J. R. H. NEERVOORT van de POLL. The new species of Odontolabis described below originates from Palawan , one of the Philippine Islands , situated be- tween the northern part of Borneo and Luzon , and forms a most interesting connecting link between O. alces F. from Luzon , and 0. celebensis Leuthn. from Celebes , bearing in general appearance even a greater affinity to the last named species, the dentition of the mandibles however corresponding with 0. alces F. The great length of the mandibles, which in the mesodont form are longer than the head and prothorax together, is very remarkable and unique for the so-called a/ces-group. Now British North Borneo becomes the more and more explored , I have some hope, that, within a short time, an allied form from Bor- neo will also be brought to light, which I consider to be of high importance for the real appreciation of the allied species, scattered over these islands. Odontolabis intermedins, v. d. Poll. Male. Uniform deep black; mandibles, head, prothorax and legs dull, very finely punctured; elytra pitchy black with a bright obsidian lustre. Head large, quadrangular, much longer than the prothorax , front edge strongly emar- ginate , sides straight in front , canthus very narrow, post- ocular tubercles very much developed, obtuse and strongly directed forwards, the lower part of the cheeks coarsely Notes from the Ley den Museum, "Vol. XI. 15 226 ODONTOLABIS INTERMEDIUS. wrinkled and pitted, the uppersurface near the eyes also distantly pitted. Prothorax twice as broad as long , its front edge strongly emarginate on each side , the sides trispinose with two very deep concavities , the middle spine very long and acute, undersurface smooth , the lateral margin coarsely wrinkled. The prosternal process is well developed and projects strongly in front and beneath ; the mesosternal process hardly prominent. Elytra elongate , oval. Front tibiae with three spines above the terminal fork , of which the uppermost are rudimentary in the large development. As for general aspect and brilliancy of the wingcases it agrees well enough with 0. celebensis Leuthn. , but it is a larger and comparatively a more slender species, its pro- thorax is much flatter with the middle spine much longer and more acute , projecting sidewards in a straight manner and not downwards as in celebensis, its tubercle below the eyes is also much larger and directed obliquely forwards. O. alces F. is a more dull looking, broader species, with the middle spine of the thorax not very acute and the tubercle behind the eyes large and obtuse but not directed forwards. Mandibles. Forma mesodonta. Mandibles longer than the head and prothorax together, very slender, rounded, curved downwards, the tip slightly turued upwards , with three apical teeth of which the innermost is rather large and the two other ones very minute, and a strong tooth beyond the middle, projecting obliquely inwards not downwards. Head with raised crest. In general shape the mandibles are very much like those of the teledont form of 0. celebensis Leuthn. but they recede from them by the want of basal teeth. The dentition cor- responds with that of the mesodont form of 0. alces F. , and it is this analogy, which made me suppose, that a still higher development, without the large tooth beyond the middle , might occur in my intermedins just as in alces, Notes from the Leyden Museum , Vol. XI. ODONTOLABIS INTERMEDIUS. 227 but on the other hand , the great length of the mandibles renders this supposition somewhat doubtful. The examination of an extensive series only will enable us to settle the question satisfactorily. Forma amphiodonta. Mandibles longer than the head, straight , rounded , with four apical teeth , strongly expanded inwards , at the base with three obtuse teeth. In the unique specimen I have , the basal teeth of the right mandible are entirely melted together, forming a single broad blunt appendix ; on the left side the two undermost teeth are but faintly indicated , whilst the uppermost is rather strongly projecting. Female. Very much like that of 0. celebensis Leuthn. and 0. alces F. ; as far as I can judge from the single exponent I have at my disposal , it differs from both in a few pecu- liarities of the prothorax , viz. : the front angles are angular instead of broadly rounded , the lateral concavity before the middle spine is deeper and the spine is more prominent and acute. The uppersurface is neither so glossy as that of celebensis, nor so dull as that of alces. The front tibiae have four spines above the terminal fork. Measurements.

AEGUS CAPITATUS. 229 NOTE XLVIII. ON AEGUS CAPITATUS, WESTW. C. RITSEMA Oz. Among the Lucanidae brought together iu Deli (East- Sumatra) by Dr. B. Hagen and presented by him to the Leyden Museum, I found a male specimen of minor deve- lopment , belonging to the genus Aegus , which was at first sight unknown to me. A careful examination , however , convinced me of its close relationship with Aegus capitatus Westw., a species represented in Dr. Hagen's collection by a few males and females, but I could not decide whether it was the extreme varietas minor of this species or that of a new one. I wrote therefore to Mr. Neervoort van de Poll asking him to look at the matter , and most courteously he sent me from his extensive collections all connecting links between my specimen and the varietas major of Aegus capitatus. Taking into consideration that among the described forms of the male of this species the smallest form (that what I regard as the true var. minor) is not to be found, I thought it not without interest to publish a detailed des- cription of it. With the higher developed forms it has some important characteristics in common, viz.: the shape of the inner edge of the mandibles with the conical basal tooth on a level below that of the surface ; the shape of the fore margin of the head between the mandibles (broadly and angularly emarginate, the emargination terminating in a produced point at each end); the shape of the hinder an- Notes from the Leyden Museum, Vol. XI. 230 AEG US CAPITATUS. gles of the thorax (subangular , not emarginate) ; the con- formation of the lateral margin of the second and following abdominal segments (thickened and glossy, widened out on the last segment where this margin is notched at the apex). Before to proceed to the description of the var. minor, I ought to say that the males which have a spine or tu- bercle on each side of the head between the eye and the produced point of the fore margin, are regarded by me as the var. major, those without these spines or tubercles but with the mentum and jugulum opaque as the var. med., and that the form which I believe to be the var. minor may be characterized by its small size , by the total or nearly total absence of the tooth which proceeds from the upper surface of the mandibles a little before the base, by the shining (Dot opaque) and deeply punctured men- tum and jugulum , and by the subcostate elytra. The three different forms may at once be recognized by the follow- ing key: I. Mentum and jugulum opaque , impunctate or provided with shallow , margined punctures. a. Head with a spine or tubercle between the eyes and the produced points of the fore mar- gin var. major. b. Head without spines or tubercles. . var. med. II. Mentum and jugulum shining, provided with deeply impressed punctures. ...... var. minor. Aegus capitatus Westw. cf , var. minor. I have taken the following description from four speci- mens: one, the smallest, measuring with mandibles 21.5 mm. '), belonging to the Leyden Museum and originating from Serdang (East-Sumatra) ; the three others , measuring with mandibles 22.5, 23.5 and 24.5 mm., belonging to 1) The largest male with which I am acquainted (likewise from Serdang) mea- sures with mandibles 47 mm. Notes from the Leyden Museum, "Vol. XI. AEGUS CAPITATUS. 231 the collection of Mr. Neervoort van de Poll and coming from Malacca. Black above , dark reddish brown beneath ; subshining. The mandibles glossy, covered with punctures which be- come finer and finer towards the tip and on the inner basal portion (basal tooth); they are as long as or slightly longer than the head , strongly and regularly curved , and provided internally, a little before the base and on a level below that of the surface of the mandible, with a conical tooth. Moreover in the two largest of my specimens a trace of the tooth is present which proceeds from the upper sur- face at some distance from the base. The head is densely covered with large punctures which bear short erect fulvous hairs and are partially confluent especially towards the fore margin and the eyes. The fore margin between the mandibles broadly and angularly emar- ginate, the emargination terminating in a produced point at each end. The anterior lateral angles are rounded off, the ocular cantbus is entire , and the sides are convex and slightly sinuate. From the anterior lateral angles a curved smoother carina runs to the inner orbit. The prothorax somewhat broader than the head and with parallel sides , or (as in my smallest specimen) in front as wide as the head but somewhat broader at the base; it is densely and rather equally covered with large and deep punctures which are confluent along the margins and bear erect short fulvous hairs; the middle of the disc is shallowly impressed and provided with some larger and partially confluent punctures; the anterior angles are pro- minent and more or less narrowly rounded off, the poste- rior ones subangular, not emarginate. The scutellum has a few large punctures. Each elytron shows four deeply impressed striae of con- fluent punctures, forming in connection with the suture five glossy interstices which are alternately more elevated and four of which disappear before the end; the interstices are sparsely provided with very fine punctures, the 2nd Notes from the Leyden Museum , Vol. XI. 232 AEGUS CAPITATUS. and 4th moreover coarsely punctured at the basal portion; beyond the 5th interstice as well as at the end the elytra are rugose in consequence of a very dense and confluent sculpture, with the exception of two narrow costae origi- nating from the shoulder (the inner one much more dis- tinct) and the apex of the sutural interstice which are smoother; the shoulders are pointed, the outer margin of the elytra minutely crenulate, and the striae and rugose portion provided with short erect fulvous hairs. The under surface and legs sparsely covered with short erect fulvous hairs; the jugulum and mentum shining and covered with large and deep punctures which are wider apart on the jugulum; on the basal portion of the latter a narrow but deep transverse furrow occurs in the small- est specimen (that from Serdang). The lateral portions of the head are very shining and show a few large punctu- res; the base is finely rugose as well as the middle of the prosternum , the sides of which are , however , very shining, nearly impunctate; the centre of the metaster- num is finely and distantly punctate, the rest shows a somewhat reticulate sculpture; the epipleural fold of the elytra has an indistinct reticulate sculpture. The abdomen is rather strongly and equally punctured ; the lateral mar- gins of the 2nd and following segments are thickened and glossy, widened out on the last segment where this margin is notched at the apex. The anterior tibiae are serrated along the outer margin , the intermediate and posterior ones armed with two spioes, one about the middle, the other (the smaller one) between the middle and the base. Aegus capitatus Westw. is as yet recorded as inhabiting Malacca , Prince of Wales' Island , Sumatra , Banca and Borneo , whereas the allied Aegus labilis Westw. (? paral- lelus Hope) , a species known to me by description and figure only, originates from Darjeeling. Notes from the Leyden Museum, Vol. XI. SUMATRAN LUCANIDAE. 233 NOTE XLIX.

I believe, however, this statement to be based upon incorrect identification of specimens of the Sumatran Eurytrachelus purpurascens Voll. (? = elaphus Herbst). Aegus acuminatus Fabr. is likewise recorded by Parry as a Sumatran species. Most probably, however, these speci- mens belonged to the Sumatran Aegus ogivus H. Deyr. Aegus impressicollis Parry. — Four specimens (three males of the varietas minor and a female) brought home from Sumatra by the Dutch Scientific Sumatra-Expedition were sent back by Parry under the above name. A careful examination , however , convinced me that these specimens belong to Aegus ogivus H. Deyr. Three other species, recorded by the authors as coming from Sumatra , are unknown to me , viz. Lucanus (Aegus) lunatus Weber, Lucanus (Aegus) inermis Fabr. and Luca- nus (Figulus?) punctatus Fabr. On the other hand I am acquainted with an unnamed Sumatran species of Prosopocoelus (a Q from Deli in the Leyd. Mus.), Cyclommatus (a Q from Deli in the Leyd. Mus.) and Aegus (a <ƒ from Mt. Singalan in the Genoa Museum. Finally three species of Lucanidae are described from Nias, an island west of Sumatra , which species perhaps may also belong to the Sumatran fauna, viz. Cyclommatus Maitlandi Parry (not identical with C. faunicolor Westw.) , Odonto- labis gracilis Kaup and Odontolabis inaequalis Kaup. Notes from the Leyden Museum, Vol. XI. APHANISTICUS KRUGERI. 237 NOTE L. A NEW JAVANESE SPECIES OF THE BUPRESTID GENUS APHANISTICUS, LATR. DESCRIBED BY C. RITSEMA Cz. Aphanisticus K rüg er i, nov. spec. The nearest ally of this species will prove to be A. pa- radoxus H. Deyr. from the island of Makian (Ann. Soc. Ent. Beige. VIII. p. 223, and p. 227, pi. 4 fig. 20). It has a length of about 3 — 2lj2 mm. and is of a blackish bronze colour, bright bronze on the head and pronotum. — The whole insect is covered with an extremely fine and dense sculpture which is only visible with the aid of a lens of strong power. The head is short, narrowly and rather shallowly exca- vated between the eyes , the inner orbits slightly produced in front, which makes the head (seen from above) angu- larly notched at the anterior margin. It is smooth, provided with a few large but shallow punctures at the bottom of the frontal excavation and on the cheeks. Prothorax transverse , widest about the middle , and wider at the base than at the tip ; the sides flattened , regularly rounded, and very slightly (almost inconspicuously) con- stricted just before the base ; the anterior angles acute and protruding, the basal ones subrectangular and with the margins turned upwards ; the base bisinuate , provided in the middle with a broadly rounded lobe ; the strongly convex disc is separated from the anterior margin by an impressed line of large but shallow punctures and from the basal lobe by a distinct transverse impression ; the disc Notes from the Leyden Museum, Vol. XI. 238 APHANISTICUS KRUGERI. itself is divided behind the middle by a transverse impres- sion which is interrupted in the middle. The pronotum is smooth showing only a few shallow punctures in the trans- verse impressions and on the flattened sides. The scutellum is small and has a regular triangular shape with acute apex. The elytra at the base as wide as the base of the thorax, the lateral angles angular, the sides parallel as far as half their length (slightly sinuated behind the shoulders), then obliquely narrowing in slightly convex lines till a little before the apex where they become parallel ; the apices subtruncate with broadly rounded external angles; the shoulder-region prominent in consequence of an impression between it and the lateral margin, and the suture on the greater apical third raised in consequence of an impression which accompanies it. The sculpture of the elytra is sub- ject to some variation : 1 . the elytra are covered with large but ill-defined punctures which are arranged in longitudinal rows and which become less and less distinct towards the end and are nearly absent along the apical 3/4 of the su- tural region ; 2. the punctuation is very indistinct and confluent and only present on the basal fourth ; 3. no dis- tinct punctuation but traces of raised longitudinal lines on the basal half; 4. the raised longitudinal lines very distinct and continued till a little before the apex. Under surface and legs smooth and shining, the sternum and the two basal segments of the abdomen provided with some very shallow punctures. Of this species I received a few specimens , together with larvae and pupae, from Dr. Krüger at Kagok (Tegal : Java) to whom the species is dedicated. The larvae were found mining in the under surface of the leaves of sugar-cane , where they undergo also their transformations. They are allied to those of Aphanisticus emarginatus Fabr. (E. Perris, Larves de Coléoptères. (Paris, 1878) p. 149—153; pi. VI, fig. 182 — 188) but remarkable by their being deeply con- stricted between the segments. Notes from the Leyden Museum , Vol. XI. DRILL! A ALBOTUBEBCULATA. 239 NOTE LI. DESCRIPTION OE A NEW SPECIES OE DRILLIA. BY M. M. SCHEPMAN. Drillia (Clavus) albotuberculata, Schepman. Shell elongate , dark fleshy brown , with large white rib- like nodules and a white infra-sutural line; whorls 10, the apical ones a little eroded, smooth, the next 2 with rather indistinct ribs, the rest with conspicuous white nodules , which become larger up to the last whorl ; on this whorl , which is somewhat oblique , they are smaller on the ventral side, it shows a very large nodule before the aperture and a second row of much smaller ones, which are not visible on the upper whorls. The surface of the shell is covered with faint spiral lirae , which are more distinct on the nodules. Suture linear , irregular in consequence of the nodules of which there are 9 on the last whorl, besides 12 of the second row, and 6 or 7 on the upper whorls, where they occupy nearly the whole breadth, except a narrow zone at the upper part of each whorl. Aperture rather small, the interior white with fleshy brown spots near the margin, sinus large, rounded, not deep, lip thin, arcuate and prominent, slightly crenulate. Canal very short and large , columella slightly curved , with a brown callosity, its lower extremity produced, near the suture with a strong tubercle. Length 42, diam. 20 mill. Length of the apert. 17 mill. Habitat unknown. Notes from the Leyden Museum, Vol. XI. 240 DRILLIA ALBOTUBERCULATA. This species may be easily recognised by the strong white nodules, which cover nearly the whole surface. After careful research in the monographs of Kiener, Reeve and Weinkauff, I sent my specimen to Mr. E. A. Smith in London , who was kind enough to compare it with the specimens in the British Museum , and who agreed with me in considering it as a new species. Drillia (Clavus) albotuberculata , Schepman. Notes from the Leyden Museum, "Vol. XI. SUMATRAN COLEOPTERA. 241 NOTE LIL ON SOME SUMATRAN COLEOPTERA WITH DESCRIPTION OF A NEW GENUS AND SPECIES OF LONGICORN. BY C. RITSEMA Cz. Some days ago I received from Mr. J. D. Pasteur of Padang Sidempoean (res. Tapanoeli , Western Sumatra), a few Cole- optera presented to him by Mr. K. E. Keil , a military surveyor of the topographical service, who captured them in March of the present year in the neighbourhood of the above locality , on the eastern summit of Mt. Loeboe Raja at an elevation of about 2000 M. above the level of the sea. These beetles , one of which proved to be new to science , belong to the following species: 1. Odontolabis Lacordairei Vol!. — A female of the va- riety without the round orange-red spot on the front an- gles of the prothorax, and with the black suture as nar- row as in the male. It has a total length of 38 mm. — Another, somewhat larger female specimen (41 mm.), pre- sented to the Museum by Dr. Klaesi and likewise origina- ting from Western Sumatra , shows faint traces of the red spots on the pronotum, and a suture narrowly edged with black. — A large series of males and both forms of the female (typical form and variety) has been sent over by Mr. J. A. N. Schagen van Leeuwen from Kotta Zuyde- wijn near Solok (Western Sumatra). 2. Aceraius emarginatus Fabr. — Two specimens. 3. Xylotrupes Gideon Linn. — Two females. 4. Macronota Ludekingi Voll. — Four males and three JN"otes from the .Leyden Museum, "Vol. XI. 16 242 SUMATRAN COLEOPTERA. females. — The type-specimen of this species is a male. The female has been described by Dr. Gestro (Ann. Mus. Civ. Gen. 1879. p. 10) under the name of Macronota sumatrana. — Both sexes were also found by Mr. Schagen van Leeuwen at Kotta Zuydewijn. 5. Pseudochalcothea virens Rits. (= Bockii Lansb.). — One male and two females. — The female alone was known up to this date: Sumatra-Expedition, Singkarah ; van Lans- berge, Ajer Mantjoer; Schagen van Leeuwen, Solok; Dr. Klaesi, Padang. The male differs from it (besides by the common sexual differences , viz. narrower shape, longer antennal club , longitudinally impressed abdomen) by having elongate tarsi, slender and elongate unarmed front tibiae, slightly curved middle tibiae, and hind tibiae which are feebly curved (the concavity on the outer side) and provided on the middle of the inner side with a compressed and acutely pointed curved appendage , which is obliquely directed inwards and backwards and reaches to the end of the tibia. Moreover the inner apical spur of this pair of tibiae is subacute, not broadly truncate at the apex as is the case in the female. Finally the sutural notch at the end of the elytra and the impression at the end of the pygidium is deeper, and the apical ventral segment is shorter and nearly impunctate. — The shape of the mesosternal process seems to be not quite constant in this species , at least in my Loeboe Raja spe- cimens it is prolonged at the tip and consequently more acute with feebly sinuate sides; moreover the tibiae and tarsi in these specimens are not bright coppery but green with a faint golden hue on the upper side, and the palpi and antennae are dark piceous with metallic green tinges in stead of bright reddish brown. 6. Campsosternus rosicolor Hope var. ? — One specimen. 7. Ananca spec. — A very mutilated specimen of a large cin- namon coloured species which has the legs slightly infuscate. 8. Chloridolum Klaesii Rits. — A single female specimen. — This species seems to be somewhat variable as to the sculp- ture of the head and pronotum. On the former the double Notes from the Lpyden Museum , Vol. XI. SUMATRAN COLEOPTERA. 243 curved transverse line at the base of the clypeus is wanting in this female, whereas the transverse striae on the pro- notura are more distinct and occupy nearly the whole sur- face. Moreover the bare stripes on the elytra are metallic green , not coppery as in the type-specimens. 9. Pseudanhammus (n. g.) Keili, nov. spec. — A single male specimen. It is not without some hesitation that I propose a dis- tinct generic name for this , I believe undescribed species of Monohammid. After a careful examination I could find no better place for my insect than in the genus Anham- mus or Monohammus with which it has the majority of characters in common, viz. a declivous mesosternum which is neither produced nor tubercled , a strongly spined thorax , eyes of moderate size and not approximate in front, elon- gate antennae, a scape with a cicatrix, the head subqua- drate (not transverse) in front , etc. From the former genus , to which it bears a strong resemblance in the habitus, it differs, however, by the want of a tooth at the shoulders, and by the different situation of the thoracical spines which are placed about the middle of the sides. From the latter genus it differs by the strongly granulate base and shoul- ders of the elytra, which granules are gradually replaced by deeply impressed punctures which are arranged in lon- gitudinal rows and become less and less distinct towards the end; moreover by the shape of the thoracical spines which are slender and obliquely directed upwards. Finally the new genus differs from both by the different confor- mation of the prosternum between the anterior coxae , this being not rounded but wedge-shaped , perpendicularly rai- sed to the level of the coxae, and furrowed along the middle of the whole front side which gives the top a bi- partite appearance. The generic name of the present insect is derived from its strong resemblance to a dwarf-specimen of Anhammus Daleni Guér. The specific name is given in honour of its captor. Notes from the Leyden Museum , Vol. XI. 244 SUMATRAN COLEOPTERA. Length, from the top of the aiitermary tubers to the end of the elytra , 20 mm. ; breadth at the shoulders 7 mm. — Black, with the antennae (the scape excepted) dark brown. Head , thorax , under surface of body , and legs (with the exception of the tarsi which show a bluish grey pile) densely covered with a pale ochreous pubescence , va- riegated with bare dots which are irregularly confluent on the sides of the abdomen; the antennae are likewise co- vered with a pubescence which is pale ochreous on the scape and 3rd joint , but more greyish on the basal- , brown on the apical half of the succeeding joints. The elytra are variegated with irregular spots of a very dense pale ochre- ous pubescence, which spots are more or less confluent in a transverse direction, so as to form three very irregu- lar bands, one across the base including the densely pu- bescent scutellum , the 2nd before , the 3rd behind the middle ; moreover the elytra are sprinkled all over with small dots of a looser but similarly coloured pubescence. The sculpture of the head is concealed by the pubes- cence, with the exception of an impressed mesial line ex- tending from the front margin up to the front margin of the thorax. The head is triangularly concave between the an- tennary tubers which are prominent and, at their base, only separated by the smooth mesial line. The cheeks are as high as the inner orbit of the lower lobe of the eyes, the face subquadrate, broad but not transverse. The an- tennae twice as long as the body ; the scape as long as the 6th joint and gradually thickened on the outside be- hind the middle , which conformation gives it a somewhat cur- ved appearance ; the cicatrix rather large, pubescent, not com- pletely margined at the inside; the 3rd joint the longest, the 4th slightly longer than the 5th, this latter slightly longer than the 6th which is equal in length to each of the succeeding joints, the apical one excepted which is nearly as long as the 3rd. The thorax has one frontal and two basal grooves pa- rallel with the margins; the disk is somewhat uneven and Notes from the Leyden Museum, Vol. XI. SUMATRAN COLEOPTERA. 245 shows a few irregularly placed hair-bearing granules , and in the centre a few wrinkles. The lateral spines are placed about the middle and obliquely directed upwards; they are long, rather slender and acute and glossy black. The scu- tellum is very broadly rounded posteriorly. The elytra are gradually narrowed towards the end; they are provided at the base, especially on the promi- nent and somewhat compressed shoulders, with numerous glossy granules which are gradually replaced by deeply impressed punctures arranged in longitudinal rows and becoming less and less distinct towards the end. At the base , between the shoulders and the scutellum , a feeble crest is present which is beset with glossy granules. The apices are narrowly truncate with very blunt angles. The bare dots on the under surface and legs are im- punctate. The apical ventral segment is longer than the preceding one , and broadly truncated posteriorly with roun- ded lateral angles. 10. Thysia tricincta Casteln. — A single specimen. To this lot Mr. Pasteur joined some Butterflies ') from Padang Sidempoean (situated at an elevation of about 1000 feet above the level of the sea) and three insects captured (likewise by himself) at the Upper Bila , during a journey from Padang Sidempoean to Deli. One of these specimens is identical with the larva de- scribed and figured in 1831 by Perty in his »Observatio- nes nonnullae in Coleoptera Indiae orientalis" (p. 43, fig. 8 and 9), and which is said to be that of an Episcapha- species. It was found by Mr. Pasteur in dense forest , slowly walking on a fallen tree , and has , according to its cap- tor, after death undergone no change whatever, neither in form nor coloration. The second is a specimen of Lanternfly (Hotinus pyro- rhinus Donov.). Mr. Pasteur writes me that he had kept 1) Ornithoptera Amphrysus Cram., Papilio Memnon Linn., Papilio Antiphus Fabr., Papilio Polytes Linn., and Papilio leucothoe Westw. Notes from the Leyden Museum , "Vol. XI. 246 SUMATRAN COLEOPTERA. it alive (and in good condition) during two days and nights , but that he did not observe the slightest luminosity in it. The third is a specimen of a very interesting Longi- corn , viz. Bradycnemis velutina C. 0. Waterh. , a species of which the native country was not yet known with cer- tainty. J*. S. In a recent paper on new Coleopterous insects from Mount Kinibalu , North Borneo (Proc. Zool. Soc. London. 1889. p. 383) Mr. H. W. Bates describes several new species of Cetoniids which partly belong to new , partly to already known genera. Among the latter are species of the genus Plectrone which is regarded by Mr. Bates as a mere section of the genus Chalcothea. Moreover Mr. Bates supposes my genus Pseudochalcothea to be synonymous with Plectrone. This latter supposition may be correct, the first is certainly erroneous. Though the materials belonging to these genera are not very extensive in our Museum, I believe to have found a good characteristic that, besides the margined pronotum and, in the cT, the armed hind tibiae, will serve to dis- tinguish the genus Plectrone (and Pseudochalcothea) from Chalcothea. In the 9 °f Plectrone (and Pseudochalcothea) I find the end of the upper side of the hind tibiae bicuspi- date , whereas in the 9 Chalcothea it ends in a single spine. The distinctive characteristics thus contrast as follows: I. Sides of pronotum not margined. Hind tibiae in the cT simple, their upper margin in the Q ending in a single spine Chalcothea. II. Sides of pronotum margined. Hind tibiae in the cf provided on the inner side with a compressed spur or appendage , their upper margin in the 9 bicuspidate at the end Plectrone , Pseudochalcothea.

The Leyden Museum possessed already a specimen cap- tured by Dr. de Gavere near Batavia, when recently two specimens were sent over by Mr. Lucassen from Boemiajoe (Tegal : Java) at the feet of Mt.

Birman. p. 51, pi. 2 fig. 21)) that, notwithstanding the different localities, I dare not treat our Javan insect as distinct. The only character of which no mention is made in the careful description , is the presence of rows of very large and closely set trans- verse piceous dots on the elytra. 1) According to the Munich Catalogue, H. apicalis Schm.

DESCRIPTIONS OF THREE NEW SPECIES OF THE GENUS PHYSODERA (CARABIDAE). J. R. H. NEERVOORT van de POLL. The genus Physodera has been established already in 1829 by Eschscholtz for a species (P. Dejeani Esch.) with very singular inflated sides of the thorax. Twenty years afterwards Major Parry added a second species (P. Esch- scholtzi Parry) to the genus , which entirely wants that peculiarity, however, in all other respects agreeing per- fectly well with the type of the genus. Both species have been originally described from the Philippine-Islands , but Major Parry made already mention that he himself pos- sessed a specimen of P. Eschseholtzi from Ceylon. Subse- quent explorations have shown that they are both very widely distributed. Schmidt Göbel in his Faunula coleopte- rorum Birmaniae" records P. Dejeani Esch. from Tenas- serim and Dr. Hagen sent over to the Leyden Museum , specimens from East-Sumatra (Deli) , together with exam- ples of P. Eschseholtzi Parry , which is also known as an inhabitant of Borneo and Java. Having such a wide range, it is not surprising that these species are subject to cer- tain modifications. The elytral colour is very variable, even specimens from one and the same locality differ within the limits of golden-bronzy to violaceous-purple. The tho- rax of Eschseholtzi I found very inconstant in outline , being considerably larger in some examples than in others , and the elytral sculpture of that species is sometimes very Notes from tlie Leyden Museum, Vol. XI. 252 PHYSODERA DAVIDIS. distinct, sometimes quite obsolete. Recently Fairmaire described a new Physodera from China , Fokien , under the name of P. Davidis Fairm. As the whole description does not contain a single expression, which should not apply perfectly well to P. Eschscholtzi , and moreover, as the diagnosis is not accompanied by a single word of compa- rison, which should let us suppose that the author has known the existance of Eschscholtzi, I shall allow myself to regard P. Davidis Fairm., until better evidence of its specific distinctness will be given , as a mere synonym of P. Eschscholtzi Parry. I shall now proceed to describe in this paper three more species of Physodera ; two of them , originating respecti- vely from Hongkong and Celebes , are closely allied to P. Eschscholtzi; whether they must be regarded as distinct species or as local forms of Eschscholtzi, is a matter of opinion, but looking both very different and deserving certainly a name, I do not see much harm in treating them presently as distinct. The third species , which has been already for a long time in the collection of the Ley- den Museum, is labelled »Java" and is as different from the two old species , as these are mutually.

Underneath and legs piceous with a bronzy hue, very shining. Head smooth with two elongate shallow impressions be- tween the antennae and a third small one in the middle.

Elytra subquadrate and moderately convex , with the shoulders broadly roun- ded , the sides slightly swelling out downwards , the apex largely truncated; distinctly punctate-striate , the punctures diminishing towards the margins and the apex, the inter- vals plain and smooth. Undersurface almost smooth. This species is extremely close to P. Eschscholtzi Parry, but may be distinguished by its smaller prothorax, which is much narrower than in any specimen of Eschscholtzi I have seen , and by its elytra being narrower and altogether longer.

P. Eschscholtzi Parry, proxima , sed elytrorum colore diversa et prothorace leviore et ma'gis rotundato-ampliato ab angulis anticis usque ad medium, facilis ad distinguendum. Long. 12 mm. Habitat: Bontliain, S. Celebes (C. Ribbe!). Uppersurface brightly shining; head and prothorax black , the latter with bluish tinges chiefly at the sides; elytra dark cyaneous with strong violaceous reflections; underneath and legs piceous with a bluish hue , very shining. Head smooth with two rather obsolete impressions be- tween the antennae. Prothorax broad, the sides much ex- panded and strongly rounded in the middle, the front angles broadly rounded and pilose, the edges, formed by the lateral emargination , rather acute , the lateral margins but slightly reflexed , the disc transversely depressed pos- teriorly, very smooth , with the median line obsolete , the subconcave sides also almost plain. Scutellum triangular, acute. Elytra subquadrate , moderately convex, with the shoulders strongly rounded, the sides slightly enlarged towards the top, which is broadly truncated; rather finely punctate-striate , the punctures becoming smaller towards the margins and the apex which latter they do not reach , the intervals plain and smooth. Below almost smooth. Also very close to P. Eschscholtzi Parry, but of a dif- ferent colour, the head and thorax smoother, moreover the thorax is not so angular at the sides , more rounded to- wards the front angles.

Haec species structura prothoracis, colore et sculptura ab omnibus valde discrepat. Long. 9 mm. Habitat : Java (Blume !). Smaller and narrower than any of the already known species. Uppersurface very shining, however, not quite so brilliant as usual. Head black ; prothorax fulvous with a broad irregular black band along the middle and a large round black spot on each side (these markings pro- bably very variable) ; elytra purplish-black with the apex edged with testaceous; the exposed upperpart of the last abdominal segment testaceous with a round black spot in the centre and another smaller one on each side; under- neath and legs piceous, the last ventral segment bordered with testaceous. Head with a transverse rather deeply impressed groove in front, finely rugose along the eyes, smooth on the vertex. Prothorax very wide, almost twice as broad as the head and but a little narrower than the elytra at the base ; the sides not angular in the middle but strongly rounded in a curved line towards the front margin, by which there are no regular front augles , however, the very spot of the angles is indicated by the usual pilosity; the acute edges before the hinder angles are also absent Notes from the Leyden Museum, Vol. Jd. 256 PHYSODERA AMPLICOLLIS. or perhaps it is more correct to say that they coincide with the hinder angles, and therefore the basal margin is much longer than usual ; the disc with an impressed median line, abbreviated anteriorly and posteriorly, finely rugose aloug the frontal and basal margins, with scattered large punctures at the sides, and in the middle. Elytra mode- rately convex, somewhat swelling out towards the apex, which is broadly truncated , the shoulders strongly roun- ded; finely punctate-striate, the intervals plain, regularly and rather closely punctured, the punctures of the same size as those forming the striae , which are consequently very indistinct. Underside almost smooth. This species is very unlike any of the known species, as to colour, sculpture and structure of the thorax. Notes from the Leyden Museum, Vol. XI. N. L. M. 1889. Plate 1.
