Rosz Braprorp, M.D., D.Sc., F.R.S., Vice-President, in the Chair. The Secretary read the following report on the additions made to the Society’s Menagerie during the month of December 1909 :— The registered additions to the Society's Menagerie during the month of December were 90 in number. Of these 61 were acquired by presentation, 9 by purchase, 11 were received on deposit, 1 in exchange, and 8 were born in the Gardens. The total number of departures during the month, by death and removals, was 171. Amongst the additions special attention may be called to the following :— One Long-eared Fox (Otocyon megalotis), from the Transvaal, presented by R. V. Doherty-Holwell, Esq., R.E., on December 22nd. One Alian’s Wart-Hog (Phacocherus africanus), from Nigeria, presented by Capt. H. Lloyd on December 22nd. Eight Chestnut-breasted Ducks (Querquedula castanea), hatched in the Menagerie on December 11th. One Green Viper (Atheris chlorechis), new to the Collection, from the Gold Coast, presented by Dr. H. G. F. Spurrell on December 23rd. Mr. 0. W. Beebe, Curator of Birds of the New York Zoological Proc, Zoou, Soc.—1910, No. I. 1 2 MR. 8. A. NEAVE ON BUTTERFLIES (Jan. 18, Society, exhibited a series of lantern-slides made from photographs he had taken on a recent Natural History Expedition to British Guiana. The following papers were read :— 1. Zoological Collections from Northern Rhodesia and adjacent Territories: Lepidoptera Rhopalocera. By S. A. Neavu, M.A., B.Sc. Oxon., F.Z.S8. [ Received November 9, 1909.] (Plates 1.-I11.*, Text-figures 1 & 2, and a Map.) The following paper is the first yet published, in extenso, of the collections of insects which I have had the opportunity of making during recent years in Northern Rhodesia and the Katanga Region of the Congo State. These collections were made on two separate expeditions. The first was during 1904— 1906, when I was in N.E. Rhodesia as Naturalist to the Geodetic Survey, then in that country. ) CATACHRYSOPS GIGANTEUS Trim. I took a long series of this fine species near Petauke, Luangwa valley, during the wet season. It appears to have two broods, one at the end of December and another in March. It frequents woodland and wooded hills and has a powerful flight, during which its white black-spotted underside is rather conspicuous. A female of this species from the Victoria Nyanza was described by Butler as the female of his hypoleucus, which itself is a synonym of peculiaris Rogenh. CATACHRYSOPS STORMSI Robbe. I took four specimens of this species on the Lufupa river, x1. It may be distinguished at once from the last by its lack of tail. CATACHRYSOPS CUPREUS, sp. n. «(Plate IT. figs. 9 d, 10 9.) A very distinct species, at once distinguished by the golden- _ bronze colour of the males. The females somewhat nagemble those of C. peculiaris* Rogenh. 36. UpPERSIDE shining golden-bronze with linear black margins to both wings. Also a well-marked black discocellular spot in both primaries and secondaries, a character not present in allied species : toward anal angle, eye-spots in areas 2 and 1c, that in the former areathe better marked, the black pupil being inwardly outlined and partially overlaid with pale blue scales, and the whole again being outlined with a white iris; eye-spot in area 1 ¢ much lass definite, partially lacking the blue colour ,and the dark indistinct pupil * ©, peculiaris Rogenh. in Baumann’s * Usambara,’ p. 331. 1910.] FROM NORTHERN RHODESIA. 59 has a tendency to be paired; a well-marked short, stout, black tail on vein 2. UnpersIDE whitish with black spots. An ochreous flush at base and along costa and outer margin of primaries and whole of secondaries, also some faint submarginal markings of a brighter orange colour and a black linear outer margin to both wings. Primaries. The following black spots and striz outlined in whitish :—an elongate discocellular; a discal row of six small elongate spots, the third, that in area 4, being placed more distally and at a different angle to the others, the last spot, that in 1 6, being small and sometimes paired. nes: With the following black spots and strie outlined spot below costa above cell-middle, a spot in middie of oath a small spot on inner margin near base ; a discal row of eight black somewhat elongate spots around cell-end from costa to inner margin, the first, that in area 7, being very large ; those in areas 3 and 2 2, of which the former is very small, placed nearer cell than the remainder; the penultimate, that in area 1c, more elongate and more distally placed. Eye-spots in areas 2 and 1¢ much as upperside, but that in area 2 has a complete blue iris and is secondarily strongly outlined externally with black. Fringe dusky ; palpi white tipped dusky ; thorax and abdomen dusky above, paler below (the vertex tinged with bronze). Length of primary 22 mm. The female is a larger insect, primary 24 mm. ‘The golden- bronze colour of the male is lacking and the upper surface 1s washed with pale blue, and there are traces, especially in the secondaries, of a submarginal row of whitish arrow-shaped markings. A variable number of the discal row of spots on the secondaries is visible on the upper surface. In the type specimen figured, these are seen in areas 4 and 5. The eye-spots on the upper surface are faintly outlined with orange-ochraceous. The under surface resembles that of the male, but is paler. There is sometimes an additional black spot immediately below the cell- middle in area | ¢. Types ¢ @ in the British Museum, from the Mansya river near’ Lake Young, 5.x1.08. Cotypes in the Hope Coll., Oxford. Described from eleven males and thirteen females from the Chambezi valley. and Mansya river, mid-October-mid-November, 1908, and one worn female from the Lufupa river, 26.x.07. This striking species seems most nearly allied to C. peculiaris Rogenh. in the distribution of its markings, agreeing with C. gigantea Trim. in the possession of a tail. Apart from the colour of the male, it differs from allied species in the blue, not orange, colour of the eye-spot and in the possession of a disco- cellular spot on the upper surface of the secondaries. This species has a fairly strong flight, and it frequents open country on the edge of patches of w oodland. 60 MR. S. A. NEAVE ON BUTTERFLIES [Jan. 18, CHILADES MAHALLAKOAENA Wallengr. I have a long series from many localities which I place under this name with some doubt. The only two typical males were taken on the Alala plateau, ix., and in the Chambezi valley, x. From further north and west, though the females seem indis- tinguishable, the males, instead of being flushed with amethyst- pink as in typical mahallakoaena, do not differ in coloration from the females. CHILADES TROCHILUS Freyer. A common and ubiquitous species. It seems to prefer dry and exposed spots. CHILADES UNIGEMMATA Butler. Zizera unigemmata Butler, P. Z.S. 1865, p. 630, pl. xxxv. figs. 4, 5. Two specimens, which, except that they have a very much paler underside, closely agree with the type of this species. They were captured in the upper Lofu valley, viii. and ix. CUPIDOPSIS HIPPOCRATES Fabr. A scarce insect on the low ground of the Luangwa valley or the river valleys of Katanga. Common on the high plateau. EVERES MICYLUS Cram. An uncommon insect taken occasionally in the upper Kafue, Lualaba, Chambezi, and Lake Bangweolo districts. NEOLYCANA cIssus Godt. A fairly common species everywhere. It is on the wing all the year. NEOLYCENA JOBATES Hopff. I found this an uncommon insect in the Luangwa valley and on the upper Kafue river, but did not meet with it elsewhere. ZIZERA ANTANOSSA Mab. I found this species of Zizera rare, and only took one specimen on the upper Kafue river, x., and three others on the upper Chambezi river, iv. ZIZERA GAIKA Trim. This small species is ubiquitous. ZIZERA LYSIMON Hiibn. This species is ubiquitous and much the most abundant of its genus. ZIZERA LUCIDA Trim. This species occurs over a wide area and throughout the year, 5S ? BOER 1910.] - FROM NORTHERN RHODESIA. 61 but Idid not find it common anywhere except in the Chambezi valley and Lake Bangweolo district. Fam. PIERID4. PSEUDOPONTIA PARADOXA Feld. I found this peculiar insect not very rare on the Lufupa and Lubudi rivers, x. It frequents dense forest and the thick bush on stream-banks, etc., and much resembles Leptosia medusa on the wing. LEPTosIA MEDUSA Cram. This species is ubiquitous, but not very abundant anywhere. It frequents forest and thickets chiefly on low ground, and it is : J s ’ perhaps most common in the diy season. HERPA€NIA ERIPHIA Godt. Occurs everywhere and at all seasons, but is nowhere very abundant. Has a strong and active flight. MYLorHRIS AGATHINA Cram. A ubiquitous species and much the most abundant of its genus. MyLoruris RUPPELLI Koch. Cominon everywhere, except in the Luangwa valley where it is somewhat scarce. Mytoruris vuLet Butler. I took a small series of this species on high plateau country during the dry season. Some specimens, especially from Katanga, have a considerable amount of orange flush at the base of the primaries and a rather different apex. ‘They perhaps represent a distinct species. MyYLoruris RUBRICOSTA Mab. This species occurs over a wide area in localities suited to it. It frequents open marshy ground and river banks when not obscured by timber, ete., and has a rather weak flight. APPIAS EPAPHIA Cram. This species occurs everywhere and at all seasons. It is nowhere very abundant, the females being especially scarce. BELENOIS Grp1ca Godt. A common insect everywhere, and may often be seen in hundreds at mud-holes. The dry season form abyssinica Lucas is, during its season, more common if anything than the wet phase. 62 MR. 8. A. NEAVE ON BUTTERFLIES [Jan. 18, BELENOIS SEVERINA Cram. A very common species which, although it comes into the open at times, is much more addicted to shade than its allies. BELENOIS MESENTINA Cram. Another ubiquitous species which is on the wing throughout the year. BELENOIS CRAWSHAYI Butler. I took at Kambove, vii., the upper Kafue river, x., Lake Bangweolo, vi., vil., a good many individuals, some of which, especially the Kambove ones, are certainly referable to the above species. Until the whole zochalia group of Selenois is more thoroughly worked out, it is not possible to make any definite statements, but it would seem likely that B. formosa Butler will prove to be the wet phase of crawshayi, and that Butler was in error* in assigning to crawshayi as its dry phase his own diminuta. Amongst my material there would appear to be also a small species allied to diminuta, but probably distinct from it. In the absence of more material and of any females I do not think it advisable to describe it. B. crawshayi usually frequents open grassy country and may not unfrequently be taken at damp mud. BELENOIS CRAWSHAYI, f. naTa, f. nov. (Plate III. fig. 3, ¢.) Allied to crawshayi Butler, but differing chiefly in larger size, especially in the great breadth of the primaries and elongation of the secondaries. The markings are similar to those of crawshayi, but all the specimens have a more or less well-marked basal flush of orange-yellow on the underside of the primaries, a character which seems at least uncommon in that species. A single male from near Kambove, iv., which appears to be the wet phase of this form, is slightly smaller, and somewhat resembles the type of B. formosa Butler, which, as has been just stated, is possibly the wet phase of crawshayi. It is, however, a considerably larger insect with much heavier markings on the upperside of the secondaries, the under-surface markings being less extensive but much better defined. There is also a strongly marked orange streak on costa and a second more yellow one beyond end of costa, also faint intermarginal patches of very pale yellow around outer margins. Length of primary 30-35 mm. Type 3S in the British Museum: Lufupa river, Lualaba district, 14.x.07. Cotypes in the British Museum and Hope Coll., Oxford.

This species exhibits some points of resemblance with B. thysa Hopff., in the almost evanescent discocellular spot to the primary and the orange-yellow basal flush on the underside of that wing, but on the whole seems to be nearest to B. theora Dbl., in general distribution of its markings. With the exception of theora, it differs from all the truly African species of the genus that I can find described, in the presence of an orange-yellow discocellular spot on the underside of the secondary. This character may, however, be seen in B. grandidieri Mab., from Madagascar. Dr. F. A. Dixey informs me of the interesting fact that in the case of theora, the yellow discocellular spot is present only in West Coast specimens, not 1n those from the Congo. Type ¢, wet-season. UppersibE.—Primary. Creamy-white, the base dusted with a few black scales. A minute black discocellular line may or may not be present; costa narrowly black; a well marked apical and outer-marginal black area enclosing six internervular white streaks; this black margin projects inwardly in area 3, and is continued to posterior angle by a large spot at end of vein 2 and a smaller one on vein lL. Secondary. Base and ground-colour as primary ; a submarginal row of small internervular black spots, those in areas 4 and le usually evanescent; a marginal row of seven large black spots on ends of veins, those on 7 and 1 6 the smaller. Unversipg.— Primary. Ground-colour as upperside, the base with an ochreous flush, sometimes of considerable extent; black apex replaced by a subapical row of four spots of which third from costa is the largest, and by a marginal row of spots on ends of veins extending to posterior angle; a large submarginal spot in area 3 (the largest spot on the wing); whitish ground- colour of apex marked by internervular streaks of pale sulphur- yellow. Secondary bears a costal streak of bright vermilion (occasionally orange-coloured) ; base of wing flushed with orange, of varying extent, radiating from base along internervular spaces, especially markedinarea le. A well-marked orange-yellow discocellular spot; marginal spot much as upperside, but submarginal row of spots better developed and joined to margin by rays of orange-yellow. Fringes of both wings black with white patches on the inter- nervular spaces; palpi covered with white hairs tipped dusky ; thorax and abdomen whitish. Length of primary 51-5 mm. Type ¢ in British Museum, from 150 miles west of Kam- bove, near the Lufupa river, xi. Cotypes in Hope Coll., Oxford. The dry-season male is a smaller insect, length of primary ” 27-28 mm. It has all the markings somewhat reduced, but is’ 64 MR. S. A, NEAVE ON BUTTERFLIES [Jan. 18, specially characterised on the underside by a violaceous wash on the apex of the primary and over the whole of the secondary. This wash fades after death to a warm greyish. The vermilion costal streak 1s intensified, but the orange-yellow basal flush and black marginal spots are much reduced. The females of this species are of a pale yellowish colour with very heavy black margins to both wings. In some specimens the only spots of upperside of secondary, not merged in the margin, are those in areas 5 and 6. In one individual, the ground-colour on both surfaces is of a bright orange. In wet-season specimens, the orange-yellow flush of the under surface is very extensive, sometimes in the secondaries extending over nearly the whole wing. The dry-season phase has the same characteristic difference as in the males. This species, which is described from 67 males and 5 females, occurred pretty commonly through the western portion of Northern Rhodesia from the Kafue river as far north as Lake Bangweolo and throughout Katanga. It is most common in the more open parts of high plateau country, and is frequently seen at damp mud, the females usually occurring in the denser woodland. BELENOIS THYSA Hopff. A common species in Katanga, much less so in N.E. Rhodesia. Usually frequents woodland. PINACOPTERYX SIMANA Hopff. This species is common in the low-lying parts of the Luangwa valley, iv.ix. It frequents thickets and is particularly numerous in hot and dry country. PINACOPTERYX ASTARTE. Pinacopteryx astarte Butler, P. Z.5. 1899, p. 971, pl. Ixx. figs. 6, 7. I have a long series of this species, the identification of which I owe to my friend Dr. Dixey, taken at all seasons throughout the area under discussion. The series includes those specimens mentioned by Dixey in Proc. Ent. Soc. 1907, pp. Ixv, Ixvi. The females, especially the wet-season ones, are exceedingly difficult to distinguish from Mylothris agathina Cram., when on the wing. TERACOLUS CHRYSONOME Klug.

This species was observed only in the lower Luangwa and mid- Zambezi valleys, and then only in the dry season. It frequents extremely hot and dry spots, such as rocky hillsides, ete. It is active and restless on the wing. TERACOLUS ERIS Klug. This species is common everywhere, the males especially having a swift and active flight. TERACOLUS PHLEGYAS Butler. I met with this species only in the Luangwa valley, and then only at the lowest part of it, under 2000 feet elevation. Above this it seems to be replaced by the next species. TERACOLUS REGINA T'rim. This handsome species, especially in the wet season, is common everywhere except, as mentioned above, in the lowest ground in the Luangwa valley. It has a powerful flight, and is not at all easy to catch. When it is abundant, a dull cool morning gives the collector the best chance as, like other Pierine, it is much influenced by the weather. The dry-season females are remark- able for having acquired very much more of the purple tip of the males than those of the wet phase. In the wet phase, the purple colour is often entirely absent or represented by a mere trace. TERACOLUS ANN& Wallengr. I captured occasional individuals of this species over the whole area under discussion, but found it nowhere common. It is most common in dry and rather barren localities. 'TERACOLUS OMPHALE Godt.

These points would seem to be the south-east limit of its distribution. The only females observed belonged to the form hippocoon Fabr. The males have the curious habit of following regular routes in the forest-clearings, which they traverse over and over again at intervals of three or four minutes. Papilio HESPERUS Westw. ‘I saw a few worn specimens of this fine species on the Lufupa and Lubudi rivers, x., and found it not uncommon in the valleys of the Kalungwisi and Lofu, viii. and ix.

It frequents open grassy spots. PAPILIO LEONIDAS Fabr. Ubiquitous. With regard to the flight of this insect Marshall * has told us that south of the Zambezi it does not perform the sailing evolutions of a Danaine, and says that it would be most interesting to know whether it has assumed this flight in Central Africa. This is certainly the case; and this insect is peculiarly fond of sailing slowly backwards and forwards over a distance of some 8-10 yards. As it usually does this about 10-12 feet from the ground, it is extremely difficult from below to recognize it as a Papilio at all. When startled or feeding on flower-heads it behaves differently and is distinctly active and restless. PAPILIO ANTHEUS NYASS& Butler. A common insect throughout the area under discussion. It is particularly abundant in the hot dry weather just before the beginning of the rains, and may then be seen in numbers at damp mud. PAPILIO POLICENES Cram.

Kirx- PATRICK, F.Z.S. (Plates 1V.—VII.*, and Text-figures 3-6.) [| Received November 1, 1909.] At the beginning of February this year Mr. Alfred Mosely, C.M.G., went with a small party of experts to the island of St. Helena in order to make some enquiries into the industries and resources of the island, with the object of developing as far as possible the means by which the population could support itself. Until recently the people have been to a great extent dependent on the market and the employment afforded by the garrison and various Government works in the island. In 1903 the Boer prisoners left the island, and not long afterwards the Imperial Government decided to withdraw the whole of the garrison. To prevent distress among the inhabitants the Government has taken steps to develop the manufacture of lace and of New Zealand flax, and Mr. Mosely’s attention was directed to agriculture and fisheries. I was inyited to accompany him in order to assist * For explanation of the Plates see pp, 130 & 131. GANUGHIIGIS!

HELENA, 87 him in his enquiries concerning the fisheries and to make a Report to the Colonial Office on the results of those enquiries. My Report on the practical and commercial aspect of the subject: has been already sent to the Secretary of State for the Colonies ; but Mr. Mosely gave me every facility for collecting specimens and doing as much scientific work as was possible in the time available, and the following paper contains the results of my investigations from the scientitic point of view. I took with me a number of nets of the kinds used in England for the purpose of ascertaining by experiment how far English methods and apparatus would be successful in the waters of St. Helena; these consisted of a small otter trawl 15 feet wide at the mouth, a trammel 20 fathoms leng and 6 feet deep, a seine 10 fathoms long and 8 feet deep, and two mackerel drift-nets each 20 yards long. I also took a small tow-net of silk bolting cloth. A small spirit tank for carrying preserve specimens was lent to me by the Fish Department of the British Museum (Natural History); and when my collection grew too large for this I was able to obtain tin-lned cases in the island, which were repaired and soldered down when full bya skilled workman whom Mr. Mosely had taken with him to carry out the curing of mackerel and other fish. We left Southampton on Feb. 6th and arrived at Ascension on Saturday, Feb. 20th, at 4.30 a.m. We landed for a couple of hours and saw the turtle ponds. The female turtle land on the sandy beaches of the island from January to June and are captured by being turned over; they are used as food for the garrison, or rather crew, for Ascension is treated as a ship belonging to the Navy and under the control of the Admiralty. Here also I was interested in the extraordinary numbers of Balistes which swarmed around the ship to feed on the orange-peel, pieces of bread, and other refuse thrown overboard. Before arriving at Ascension, soon after passing Cape Verde, we saw for two whole days large numbers of Velella at the surface of the sea. They seemed about 4 inches in diameter with the vertical semicircular erest 3 or 4 inches above the surface of the water and of a bright pink colour along its border. I was not able to obtain any specimens, and south of Ascension none were seen. Flying-fish of course were seen in large numbers; they first appeared after we had passed Cape Verde, and continued to be abundant till we were approaching St. Helena, but during my stay at that island I never saw one. I endeavoured to decide for myself the question whether these fishes move their wings in flight, and convinced myself that the pectoral fins were rapidly vibrating or quivering at the moment when. the fish left the water, but that afterwards during the flight they were perfectly motionless, so that the motion of the fish is like that of an aeroplane. We arrived at St. Helena on Monday, Feb. 22nd, a little before midnight, and J spent five weeks on the island, Much of my time was spent in the native fishing-boats, making observa- tions on the different kinds of fishing, The boats are all small MR. J. 1. CUNNINGHAM ON MARINE FISHES [Jan. 18, and open; the largest are whale-boats about 30 feet long and sharp at both ends: these carry a movable mast on which a sail can be hoisted, but they are more often propelled by oars. These are used chiefly for the albacore-fishing which is carried on off the south-west point of the island; each boat carries a crew of four men. The other boats are a little smaller and have square sterns; they are used for catching mackerel and various other fish, chiefly at night, the albacore-fishing being carried on in daylight. The island is roughly oblong and extends from north- east to south-west, and as it les in the region cf the trade winds blowing always from the south-east, the north-west coast is the lee side, and the sea on this side is always smooth or moderate ; hence the open boats are perfectly safe on this side, and here the fishing is usually carried on. Seining was impossible, as there are no smooth sloping beaches on which to draw a seine; at the mouths of the valleys including Jamestown there are beaches of small extent, but they are very steep, are composed of large pebbles, and there is usually a strong surf breaking on them. This surf is due to large smooth waves, locally known as ‘ rollers,’ which come from the north-west, that is, in the direction opposite to that of the wind; their size and force varies greatly from unknown causes, and when they are heavy, landing and embarking at the wharf at Jamestown are rendered somewhat difficult. I made one trial of the trammel-net, setting it in the evening in about four fathoms of water off Banks’ Valley to the east of Jamestown. When hauled a little after a the next morning it contained 11 soldiers (Holocentrum), 4 gurnards (Seon “Bane 2 flounders (Platophrys), 2 rockfish (Scarws), 1 stone- brass (Caranx sancte helene), a large Panulirus, locally known as long-legs, one Cidaris and one feather-star. I only once had an opportunity of going to the windward coast of the island when a smal] steam-launch belonging to Messrs. Solomons, the shipping agents, towing a whale-boat, took a party as far as a small islet on the south-east coast, called George Island. It had been intended to circumnavigate the island, but the wind and sea increased so much that we were obliged to make fora sheltered bay called Prosperous Pay, where I was able to make a few hauls of the otter trawl]. I also trawled on the leeward side a little to the west of Jamestown from the town down to Lemon Valley at a depth of about 30 fathoms, where the net brought up large quantities of the massive coarse sponge identified by Mr. Kirkpatrick as Chondrosia plebeja along with the species of Hudendrium described below, six specimens of the flat-fish Platophrys podas, locally called flounders, three Scorpena, several Cidaris, two Linckia, and a specimen of Umbraculum mediterraneum. The shores of the island consist everywhere, except at the pebble-beaches at the mouths of the valleys, of black volcanic rock. The cliffs are vertical or nearly so, rising to a height of 700 feet on either side of Jamestown, and at the bases of them is a flat ledge of rock. The tide rises and falls only about two 1910.] AND INVERTEBRATES OF ST. HELENA. 89 feet, so that there is little room for shore-collecting. One of the most characteristic features is the absence of Mucus, Laminaria, and all other large seaweeds ; the surface of the rock is covered in the rock-pools with green Ulva and Hnteromorpha, and a reddish calcareous alga. There is also another alga, dirty brown in colour, and of small size. Almost everywhere the surface of the rock is closely studded with the holes inhabited by the black boring sea-urchin Hcehinometra subangularis, and on the ‘underside of overhanging ledges the large dark-coloured anemone Phymactis sancte helene is very common. I did not pay special attention to the terrestrial fauna, but it may be worthy of record here that frogs have been introduced into the island. There were none in 1875 when Melliss’ book was published, but at the time of my visit they were abundant in the neighbourhood of the Government House at Plantation and in the stream that runs down the Jamestown Valley, as far as the boundary of the town. The species has been identified by Mr. Boulenger from the specimens which I brought home as Rana grayt ne This is one of the most abundant species in South Africa, and iscommon in the neighbourhood of Cape Town, whence specimens were brought to St. ‘elem some years ago by Miss Moss, a member of one of the resident families, in order that they might furnish a supply of food for ducks. My attention was first drawn to these frogs by hearing their voices in the neighbourhood of Government House. The sound suddenly became audible a little before sunset when it began to rain; it seemed to me like the musical clink produced by tapping glass with a metal rod, in fact it rather suggested numbers of fairy anvils, and was unlike anything I had previously associated with frogs. There is one species of lizard in the island, doubtless the Hemidactylus frenatus Schleg. mentioned by Melliss. I saw one specimen on the veranda on the house where I lodged; it ran into the sitting-room and disappeared into a hole in the wainscot. Two or three large turtles were caught by fishermen and brought to market during my stay; I was informed that they are caught when in the act of copulation, the male and female remaining connected for several days, and when they are in this condition a boat can be brought close to them and one or both of the animals can be easily captured. The method of capture is to seize the animal with a gaff by one of the legs and then to pass a rope round the limb, and so either hoist the turtle into the boat or tow it from the stern. I myself saw a couple of turtles at the surface of the water when I was in a boat rowing down the leeward coast, and we rowed up to the animals, but having no gaff on board were unable to capture them. ‘There are no sandy beaches at St. Helena as at Ascension, and I never heard of any turtles going ashore to lay eggs at the former island. I saw the two giant tortoises which live at Plantation ; they are mentioned by Melliss as having been there a century or more in 1875, but the exact date of their introduction is unknown. They came in 90 MR. J. I. CUNNINGHAM ON MARINE FISHES [Jan. 18, all probability from one of the Mascarene islands; Melliss suggests that they are of the species Zestudo indica, but this species is stated by Lydekker to be extinct, and I was not able to ascertain the species with more certainty. The commonest sea-birds were G'ygis candida and Anous stolida. The former was fairly abundant in the neighbourhood of James- town, and some were always to he seen on the ledges of the vertical cliffs at the back of the wharf. It seemed to me that they were breeding there, but I did not confirm this supposition. Melliss states that the bird at St. Helena nests in rocky cliffs and dykes away from the sea, although in other parts of the world it nests in trees. At the request of the late Dr. Bowdler Sharpe I obtained two specimens of a Petrel which he identified as Oceano- droma castro; I found it breeding at Egg Island off the coast some miles west of Jamestown, and this was the first evidence of its breeding at St. Helena. Among land-birds I noticed a mynah, not the species mentioned by Melliss, Gracula religiosa, which bas become extinct, but Acrido- theres tristis; the ground-dove Geopelia tranquilla from New South Wales; the Java sparrow, Padda oryzivora; the so-called cardinal, really the Madagascar weaver, Youdia madagascariensis; Serinus Jlaviventris, often called the St. Helena seed-eater, from South Africa; and the wax-bill, known in the island as the avadavat, Astrilda astrild, also from South Africa. The latter species is seen in flocks about cultivated Jands in the interior of the island. Melliss Suanes that he introduced among other birds 26 London sparrows; but I am glad to say I saw no signs of this impudent little bird, which if it flourished would probably exter- minate others much more desirable. For kind assistance in identifying these few birds I am indebted to Mr. Frank Finn. I have myself worked out the fishes which I collected, but for the identification and annotation of the various groups of inver- tebrates I am indebted to specialists of the staff of the Natural History Museum. Dr. Calman examined the Crustacea, Mr. EH. A. Smith the few Mollusca, chiefly shells inhabited by Pagurus, Mr. Jeftrey Bell the Echinoderms, and Mr. Kirkpatrick the specimens of sponge and Hydroid. ‘To all these gentlemen I wish to express my heartiest thanks for their courtesy and assistance. I have thought it best to incorporate their reports in my paper, partly because the specimens in each group were few in number, partly because there is an advantage in keeping the results of my observations on the fauna of the island together. I have also to thank Mr. Boulenger for much friendly help and advice in reference to my work on the fishes. All the expenses of col- lecting the specimens and bringing them home were borne by Mr. Mosely, and to me personally his generosity and kindness were unfailing. To the Governor, Lieut.-Colonel Gallwey, my sincere thanks are due for his hospitality and for the very friendly interest he tookinmy work. I have also to thank the residents of the island for much hospitality and the officials for all kinds of help. 1910. ] - AND INVERTEBRATES OF ST. HELENA. 91 Relations of the Fish-fauna of St. Helena. There are 33 species in my collection, while Melliss in his book, published in 1875, mentions 68. Of those which I obtained the following are peculiar to the island :— Cheetodon sancte helenc. Julis sanctee helene. Scarus strigatus. Tetrodon cutaneus. Congromurena mellissit. Ophichthys regius. Leirus moselit, Pimelepterus gallveit. The rest may be divided into two divisions; those which are confined to the Atlantic, and those which occur also in the tropical and subtropical Pacific. Species confined to the Atlantic. Carana dentex. Lichia glauca. Murena unicolor. Murena moringa. Murena sancte helene. Holocentrum longipinne. Epinephelis ascensionis. Sargus capensis(also Muscat). Platophrys podas. Scorpena scrofina. Salarias teatilis. Ostracion quadricornis. Species common to the Atlantic and Pacific. Saurus nvyops. Priacanthus boops. Priacanthus cruentatus. Cossyphus pectoralis. Caranxz sancte helenc. Caranx ascensionis. Scomber colias. Thynnus alalonga. Thynnus albacora. Thynnus obesus. Gymnosarda alleterata. Thyrsites prometheus. Balistes buniva. In order to ascertain in a general way the affinities of the St. Helena fishes, we may enquire what species that island has in common with the Cape, with the West Indies, and with the Mediterranean. The following lists show which of the species collected by me occur in these several regions. | Species found also at the Cape. Lichia glauca. Scomber colias. Thynnus alalonga. Epinephelus ascensionis. Priacanthus boops. Sargus capensis. Species found also in the Mediterranean. Thynnus alalonga. Gymnosarda alleterata. Platophrys podas. Murceena unicolor. Caranx dentex. Lichia glauca. Scomber colias. 92 MR. J. 1. CUNNINGHAM ON MARINE FISHES [ Jan. 18, Species found also at the West Indies. Murena sanctee helene (Ber- Caranx dentex (Bermudas). mudas). Scomber colias.

Lalistes buniva. According to E, A. Smith in his paper on the Marine Mollusca of St. Helena, P. Z. 8. 1890, the molluscan fauna of the island resembles that of the West Indies, fifty per cent. of the specimens from St. Helena being common to the two localities. The similarity shown by my small collection of fishes is not nearly so great, the proportion of West Indian species, including those found at the Bermudas, being only 11 out of 33, and if we exclude the Bermudas and omit Platophrys podas, which is doubt- ful, we have only 6 out of 33. A few of the species occur both in the Mediterranean and at the Cape, namely Lichia glauca, Scomber colias, Thynnus alalonga, and probably Caranx dentes, which certainly occurs at Port Natal(Durban). The few remain- ing species show no special affinity of the St. Helena fauna with either the Mediterranean or the Cape. On the other hand, a vast number of Mediterranean and South African species do not occur at St. Helena, these being northern and southern temperate forms which are probably excluded by temperature. In fact, if we omit the oceanic forms of wide distribution, such as the species of Thynnus, the shallow-water fishes of St. Helena are few in number of species; and the fact that such a large proportion are peculiar to the island, shows how isolated the fish-fauna is, mm spite of the fact that the eggs and larve are pelagic. The fauna belongs to the tropical Atlantic, but comparatively few of the species of this fauna have established themselves on this small and isolated area in mid-ocean, and the arrival of new indi- viduals from other regions must be a rare occurrence. With regard to the species common tothe Atlantic and Pacific, it is an interesting question whether there is any interchange of individuals between the two oceans or whether the populations of the same species have been isolated since the oceans were sepa- rated by the elevation of the Isthmus of Panama. If thereisany interchange it must take place round the Cape of Good Hope, as warm-water fishes are not likely to travel round the cold shores of Cape Horn, and at the African cape the cold Benguela current from the Antarctic offers an obstacle. Scomber colias is common at the Cape, but not known in the Indian Ocean. Thynnus alalonga occurs in South African waters, but the other species of Thynnus are not recorded. JZ’. albacora occurs at Muscat, and both this species and Gymnosarda alleterata are taken on the coasts of India and the East Indies, but not at the Cape. L910.) AND INVERTEBRATES OF ST.

The Silver Eel, Melliss. . | obtained one specimen of this species, which was caught on a bottom line from a boat moored off Egg Island in about 35 fms. ; it was 18 inches long, of uniform yellowish grey colour. This species 1s peculiar to St. Helena, and only a single specimen of it, presented by Melliss, was in the National Collection until mine was added. MURNA SANCTH HELENE. (Plate IV. fig. 2.) Murena sancte helene, Ginther, B. M. Cat. Fishes, viii. p. 115; Melliss. The Bird’s-eye Conger, Melliss. I bought a specimen of this species in the market. It was 34 inches long; it has speckled markings on a chocolate ground, each mark being a group of white dots. It was a female nearly ripe, the eggs about 1 mm. in diameter, opaque, without oil globules, with thick vitelline membrane. On the inner surface of the peritoneum were oval white bodies apparently of parasitic nature. Giinther gives the length of the head as 2 that of the trunk, which means the length from the gill-opening to the anus ; if we take the length from snout toanus, the head is contained in this 33 times. The markings in Melliss’ specimen which is in the Museum are larger and more conspicuous than in mine. The long teeth are hinged so as to bend down flat inwards and posteriorly. Melliss states that this species is peculiar to the island, but there is now in the Museum a specimen from the Bermudas and another received from the Smithsonian Institution. The Madeira form Murena anatina is similar but distinct. MuR2NA UNICOLOR. Murenophis unicolor De la Roche, Ann. Mus. xiii. 1809, p. 359, fig. 15. Murena wnicolor Risso, Ichth.

It agrees with Giinther’s description except that he does not mention the vertical ascent of the forehead above the eyes; the top of the head forms a hemispherical en- largement which is continued behind into a very thick neck, while the snout is pointed and narrow. ‘There is a narrow edging of yellow round the vertical fins posteriorly from the anus and the opposite dorsal point to the caudal extremity. When the specimen was handled I noticed a liquid running from it which 94 MR. J. 'f. CUNNINGHAM ON MARINE FISHES [Jan. 18, appeared to be milt ; under the microscope particles were seen 1n this liquid which resembled the heads of spermatozoa, but none of them possessed tails. When the specimen was opened a narrow testis was found on each side not more than } inch in breadth. When a piece of the testis was teased up and examined micro- scopically, particles like those seen in the supposed milt were seen, and I concluded that these were ripe spermatozoa which had undergone partial decomposition, the specimen having been dead some time. -I concluded that the specimen was a male which had spawned and was almost entirely spent, and as it had been taken with bait and its stomach was full of food, it is evident that this species of Wurena does not die after spawning like the common conger and the freshwater eel of Europe. It occurs also in the Mediterranean, at Madeira, and the Azores. MuR2&NA MORINGA. Murena moringa Cuv. Regne Anim.; Gunther, B. M. Cat. Fishes, vill. p. 120; Melliss. Murenophis rostrata Casteln.

This species has innumerable confluent brownish-black spots separated by a fine network of the white ground-colour. The teeth are uniserial with a diastema behind large canines in the mandible and two long vomerine teeth which are hinged. I obtained a single specimen 324 inches long from an albacore-boat when I was out in another ; 1t occurs also at Bahia and the West Indies. All the Murenas are called congers at St. Helena and this one is known as the common conger, but the true Conger vulgaris of Europe, according to Melliss, is also abundant, although I did not meet with a specimen. ‘This species occurs in various parts of the tropical Atlantic; specimens in the National Collection come from Bahia, Ascension, Jamaica, Cuba, and St. Helena.

It is cylindrical in shape with a dorsal fin in the middle of the back and a small adipose fin further back. The ventral fin is extensive, reaching from the anus to the root of the tail. The pectorals are small, the pelvics much larger and thoracie in position; the mouth is enormous, extending far behind the eves which are placed close together on the top of the head; the gill-openings also are very wide. Small pointed teeth in a single row on the jaws and some on the tongue. The scales are of moderate size. The back is dark brownish with seven darker transverse bands; on the sides are several longitudinal lines of yellow. The specimen was a male with nearly ripe milt. This description is from the notes I made when | examined the fresh specimen, and the colours described may not be visible in spirit specimens. The fish lives in the sand with its eyes protruding. LEIRUS MOSELII, sp.n. (Plate V.) BVO Da Zor AG i Pe 220) VAG tee) atria 9: Sc. trans. 20/32. The most peculiar character is the posterior position of the dorsal fin which commences at a point whose distance from the end of the snout is 14 times the length of the head. Anterior part of the dorsal surface in front of the dorsal fin flat and scaled, with no trace of fin structures; a fleshy elevation at the commencement of the fin, the base of which and of the anal is imbedded and covered with scales. The single dorsal spine and the two anal spines not separate from the rest of the fin and imbedded so that they could only be detected by dis- section. Anus at about the middle of the body and ventral fin (anal) commencing immediately behind it. Length of head 32 in length of body measured from end of snout to end of middle caudal. rays. Front of head very obtuse, skin of its upper surface and round the eye scaleless and porous, but the pores not so conspicuous as in Leirus perciformis. Preoperculum with radiating ridges which project from the edge as very minute spines; edge of operculum with still more minute spinules. Operculum and preoperculum partially scaled. Eye large, its diameter 33 in length of head; no vertical lids, but a circular ridge round the orbit. “Upper rays of pectoral fin elongated, 96 MR. J. tT. CUNNINGHAM ON MARINE FISHES (Jan. 18, reaching a quarter of their length beyond the commencement of the dorsal; pelvic (ventral) fins about half the length of the ectoral. Caudal emarginate and wide. Caudal peduncle very. nearly half the length of the head, its height contained 1 times in its length. Body oblong ovate, slightly compressed. Mouth rather small, angle of the gape extending to below the vertical from anterior margin of orbit. Posterior end of maxilla exposed with small supplemental bone. Coloration brown above, paler below. The above description is taken from a single specimen measuring from the snout to the end of the middle caudal rays 72 cm. or 28; inches, its greatest depth of body being 21°5 em. or 82 inches. It was brought to me by some fishermen who called it a cod and said it had been taken in an albacore-boat, which would imply that it had been caught at a depth of 70 to 80 fathoms off the south-west point of the island. It was already eviscerated when I received it, even the gills having been cut away. I was therefore unable to examine the cesophagus to ascertain whether the tooth-bearing lateral sacs were present; but the external characters are so similar to those of other members of the family Stromateide that there can be no doubt that the fish belongs to that family. The peculiar character of the dorsal fin is so different from that of previously known species that I was for some time inclined to propose a new genus for the fish, but in its other characters it agrees so closely with the species of Leirus that I have decided for the present to place it in that genus. The generic characters of the Stromateide, as given by Tate Regan i in his revision of the family, are in most cases not very strongly marked; thus my specimen in many of its characters resembles species of Seriolella, especially S. velaini as described and figured by Sauvage, as much as it does the species of Leirus. Tt has similar falciform pectorals and the scales are not deciduous ; these characters occur, however, also in some species of Lezrus. In fact, the only character distinguishing Leirus and Centrolophus from Seriolella and other genera is that in the two former the lateral line becomes straight before reaching the caudal peduncle, and my specimen possesses this character. The spines of the dorsal fin are reduced and variable in the family generally and in Leirus in particular, and it is possible that in younger and smaller specimens of the St. Helena species an anterior spinous portion of the dorsal may exist, although there is no sign of this in my specimen, and in other species, “oneh as Leirus sortie the larger specimens have not lost the anterior spines; on the other hand, these spines are known to disappear with age in some species of the Carangide. The separation of Centrolophus from Leirus is not founded on very well marked characters, but merely on the greater elongation of the body and the slipping of the maxilla under the preorbital which is a matter of slight degree. Regan adds another character, namely, that each scale is pierced by a pore, but I have found on examination of specimens in the 1910. | AND INVERTEBRATES OF SL. HELENA. 97 Natural History Museum that this is not the case; the scales are not pierced, but when the scale is removed and the thin membrane beneath it also, a cavity is visible in the centre of the scale-area. I have named the new species in honour of Mr. Alfred Mosely. HoLocENTRUM LONGIPINNE. Holocentrum longipinne Cuv. & Val. iii. p. 185; vu. p. 496 ; Gunther, B. M. Cat. Fishes, i. p. 28; Melliss. The Soldier, Melliss. Certain sexual differences exist in this species which are not mentioned in Giinther’s Catalogue. In the male the pelvic fins reach only two-thirds of the distance from their base to the anus, in the female they extend to the anus; in the male their length is contained more than 3? in the total length exclusive of the caudal fin, in the female it is contained only 3 times in the total length. The body is shorter and stouter in the female than in the male; in the former the height of the body is contained twice in the total length without caudal, in the male 3 times. This species is regularly seen in the market, where I obtained my first specimens. It is taken in shallow water along the coast in company with Scorpena scrofina ; in my experiment with the trammel off Banks’ Valley I caught eleven specimens, but in the trawl I caught none, from which it would appear that it occurs only in the shallowest water close to the shore. It oceurs also at Ascension, the Bermudas, the West Indies, and the coast of Brazil. KPINEPHELUS ASCENSIONIS. Trachinus ascensionis Osbeck, Voy. China, 11. p. 96; Cuv. & Val. vi. p. 517.

It is common and considered a very good table-fish ; it occurs close to the shore as well as in moderate depths, and is caught either by fishing from the rocks or from a boat. The first specimen I saw was obtained from a man who had been fishing from the landing-steps in the early morning ; it was 9 inches long, and was a female not ripe. Others were caught on the windward side of the island, off George Island and in Prosperous Bay. It appears to be confined to the tropical and subtropical Atlantic, having been taken at Ascension, Barbados, Trinidad, and Bahia ; also at the Cape. Proc. Zoon. Soc. 1910.—No. VII. a 98 MR. J. 1.

This species is distinguished from all the others of the genus by the last dorsal spine being more than twice as long as the second. The membrane of the pelvic fins is black, but there is little black on the sides. I saw some of these fishes caught when I was out in an albacore-boat moored in about 80 fms.: when alive they were of a beautiful crimson-red all over except the belly, and the enormous eyes were perfectly clear and transparent, fully justifying the name Bull’s-eye, suggesting the convex lens of a bull’s-eye lantern. I opened one of the eyes and found there was no black pigment visible on the inner surface, but a bright silvery argenteum over the whole of the choroid. The black pigmented epithelium of the retina would appear to be also wanting, since, if present, it would he in front of the choroid. This condition is evidently related to vision in a dim light, and is comparable to the tapetum of crepuscular and nocturnal mammals such as the Felide. It has been suggested that the retina in such eyes is more sensitive in the presence of slight diffused light reflected from the tapetum, but it seems possible that the tapetum or argenteum may have the power of rendering dark rays more visible by altering their refrangibility at the moment of their impact on the tapetum which is in contact with the rods and cones of the retina: in other words, the tapetum may be fluorescent. In the British Museum Catalogue this species is not recorded from the West Indies, but from the South Atlantic, S. America, Cape of Good Hope, Muscat, and Japan. PRIACGANTHUS CRUENTATUS.

Both are of a general red colour, but in crwentatus the colour is darker and there is more black on the sides. In the present species the scales are smaller and the lateral line has a much steeper curve behind the head ; the eye is larger in proportion to the head and the rays of the dorsal and ventral are not so rough, in fact the soft rays are quite smooth. According to the British Museum Catalogue, P. cruentatus occurs in the tropical and subtropical Atlantic, as well as in the Pacific and Indian Oceans, the localities mentioned being Bermuda, Jamaica, West Indies, west coast of Mexico ; also Zanzibar, Samoa, Tahiti, and the Hast Indies.

Length of single specimen examined 157 inches to end of middle caudal 1 rays. I obtained only one specimen of this genus, and it does not appear to agree with any of the species previously described. It differs from P. bose Lacép., which occurs at Madeira, in having smaller scales and a smaller eye ; in fuscus Lacép., which is found at the Cape, the end of the spinous portion of the dorsal and the soft dorsal are about equal in height, whereas in my specimen the soft portion is much higher than the last spine; it difters from P. elegans Peters, in having smaller scales with their posterior apices more pointed and the body is less elongated. It resembles P. analogus Gill most closely, but in the latter there is less difference in height between the end of the spinous and the beginning of the soft portion of the dorsal, and the colour in my specimen is a bluish grey, while that of analogus is reddish brown. In P. leutescens Jordan & Gilbert, again, the eye is larger and the posterior apices of the scales more pointed. The specimen was called a breain by the fisherman from whom I bought it, the English name usually applied to fishes of the family Sparide. Melliss mentions a fish known as the bream at St. Helena, but he saw no specimens; it does not seem to be caught very often.

The colours of this Chetodont, although pretty, are not so con- spicuous as In the majority of the species in other partsof the world, a fact which is perhaps related to the absence of corals and the sombre colours of the rocks at St. Helena. The sides are silvery white ventrally, light mauve dorsally, and a band of bright yellow passes all round the body along the dorsal and ventral fins and across the caudal peduncle, the caudal fin itself beimg almost colourless. The fish is very abundant and very fearless, although at the same time not easy to capture by hook and line, as its mouth is small and it seems to know how to avoid the hook and tear away the bait, hence its local name of Cunning-fish. In ordinary circumstances not one may be seen in the water from the wharf or the landing steps, but as soon as any refuse is thrown in dozens or hundreds appear to feed on it. I tried to eatch them with a small seine shot round the fishermen’s steps, but as soon as the net was hauled in they simply escaped under its lower edge. I then used a mackerel-net, keeping the foot-line on the steps and the buoyed head-rope some distance out with the loose net hanging below the surface of the water; then by means of bait I enticed the fish over the net, and by raising the edge which had been under water I captured more than a hundred at one haul, I found they were almost ready to spawn, milt or eggs running from many of them when the abdomen was squeezed. Some of the eggs were ripe enough to float in sea-water; they were transparent, about 1 mm.in diameter, with a single yellowish oil-globule. This species and C. dichrous Giimther, of which I did not obtain a specimen, are peculiar to St. Helena, being found nowhere else in the world, while at the same time they are the only species of the genus which occur at the island.

[Received January 18, 1910. | On January 1, 1909, the number of animals in the Zoological Gardens was 3307, and during the year 1996 animals were admitted, making a total of 5303 for the year. The number of deaths during the year has been 1492, that is about 28 per cent.; but if from the above total we sinleimaclt 548 -animals which did not live for six months after their arrival in the Gardens—that is, roughly, the time at which we find they have got entirely used to their new envir onment—the percentage of deaths is reduced to 17°8, that is practically the same as the death-rate of 1908. In 1909 the total number of animals was 305 less than in 1908, and the number of deaths 245 less, The weather conditions of 1909 were not at all good, so that the percentage of deaths is really more satisfactory than in 1908, Of the 1492 animals which died, 1171 have been examined; of the rest, 131 were killed by order or by companions, 8 were preserved entire for anatomical purposes, and 182 were too decomposed for examination. The following Tables show the facts ascertained in outline, and following them are some notes on the most important points. Table I. sets forth the actual causes of death in each of the three great classes of animals, Under Reptiles are included batrachians and fishes, g* 152. DR. H. G.

Notes on the foregoing Tables. The following notes refer to a few points of special interest in connection with the diseases mentioned in the tables :— 1. It will be noticed that there is a very satisfactory decrease in the amount of mammalian and reptilian tubercle in the Gardens. Although there has been a decrease also amongst the birds, there has latterly been a considerable increase in the number of cases in the New Bird House, mainly due, in all probability, to over- crowding, but also in part to structural defects. The decrease in the Reptile House appears to have been coincident with the use of can in the cages, which is constantly changed. 2. All the cases of Mycosis: have been due to the Aspergillus fumigatus. 3. Under the term Malaria are grouped cases in which intra- corpuscular parasites, belonging to either the group of Halteridium or of Proteosoma, are tonne | in sufficient number to cause death. In the worst cases as many as 70 per cent. of the erythrocytes have been invaded. 4. In all the cases entered uncer Filaria in Table I. there has been a considerable disorganisation of the blood, and in six of the birds there has been a plugging of the cerebral capillaries by the embryos of the parasite. These birds have died suddenly with so-ealled “ fits.” On reference to Table II. it will be seen that Filaria have been found in many other cases, 43 in all. Identification in most instances has not been possible, as it is only in about a quarter of the cases that the parent worms haye been discovered. VOR 1910.] AT THE SOCIETY’S GARDENS DURING 1909. 135 In a Wallaby there were present filaria in the body-cavity and embryos in the blood; and in the body-cavity of a fetus found attached in the pouch there was also a parent worm similar to those in the mother. 5. Hemogregarines have been found altogether in 51 reptiles, in some for the first time. It is proposed to make these parasites the subject of a further communication to the Society. The blood destruction in the 19 cases in Table I. was enormous, as many as 75 to 80 per cent. (in one case 92 per cent.) of the erythrocytes being invaded by the parasites. 6. The deaths recorded under Worms were due to their pene- tration through the stomach or intestinal wall; it will be seen from Table II. that they were present in 54 other animals. A tape-worm was found in the gall-bladder of a Wallaby. 7. Pneumonia in the Mammals and Birds has been mostly of the pneumococcal variety ; in 9 of the reptiles it was a traumatic inflammation due to the irritation caused by the presence of ascaris eggs or embryos in the lungs. In some of these, which were more chronic, tubercular-like masses were formed in the lungs. 8. The starting-point of the septic absorption in these cases of septicemia was, 1n most instances, abscesses connected with the teeth. Four Wallabies had pyorrheea alveolaris. Two of the cases were due to the pneumococcus ; and in a Gayal abscesses in the kidney, due to calculi, were the starting-points. 9. The cases of broncho-pneumonia were nearly all confined to the first and last three months of the year. In four cases (Monkeys) Friedliander’s bacillus was the cause. 10. Of the 38 Mammals, the actual cause of whose deaths was congestion of the lungs, 14 had rickets badly. In the Birds, and especially in the smaller ones, owing to the structure and partial fixation of the lungs, this condition is very fatal, and is generally associated with more or less ceedema of the lungs, and sometimes with effusion of fluid into the air-sacs. 11. It will be seen from Table II. that a large number of animals—39—had fatty degeneration of the liver. Most of these were small birds, and it may in these be due to inevitable over- feeding with no natural exercise. 12. Peritonitis in Mammals was in three cases due to a sloughing appendix ; in the Birds the inflammation had spread from the oviduct. 13. On account of the large number of cases of inflammation of the intestinal tract, the investigation ito the probable causes which was begun in 1908 has been continued. It seems certain that there are five distinct varieties of enteritis in the Gardens: one caused by errors in feeding ; one caused by foreign bodies, e. g. peat, sand, hay, grass, etc.; one caused by worms, or by worm-cysts, in the walls of the intestines; one caused by bacteria ; and, lastly, one caused by protozoal organisms. The first, fourth, 136 DEATHS AT SOCIETY'S GARDENS DURING 1909. — [Jan. 18, and fifth of the above probable causes are by far the most important. With regard to the first, after every Bank Holiday there are one or more deaths due to over-feeding or to unsuitable food having been given to the animals. Again, in 95 out of 223 Reptiles there was an inflammation of greater or less extent of the alimentary canal, which—as was urged last year—would seem to suggest that the present unnatural and unphysiological method of feeding the Snakes is not the right one. Often masses of quite undigested food are found, the necessary secretions failing, apparently on account of the natural stimulus of killing the animal being absent. Of enteritis proper, 13 of the cases in Mammals and 48 of those in Birds were hemorrhagic and associated with necrosis of the mucous membrane; and protozoal organisms, mostly amcebee, were found in 49 of these. The bacterial cases occur mostly im the autumn, and some of these, I think, will have to come under the first division, since it seems probabJe that—at any rate, in some cases—the use of boiled milk, as is the case in children, may be the cause. 14. In an Iguana with nephritis, causing almost complete de- struction of the kidneys, uric acid crystals were found in numbers in the blood. 15. In this case occurring in a Bull-Frog the kidneys were entirely converted,into a transparent cystic mass containing clear fluid, and measuring 3 by 2 inches; the tissues and body- cavity were full of fluid. 16. Three new growths have occurred this year: one in a wild Swine in which both kidneys and both adrenals were involved. There were two separate tumours, one on each side of the spine. One of these was sent to the Museum of the College of Surgeons. A second one occurred in the kidney of a Lemur, and the third in the ovary of a Styan’s Squirrel. They all belonged to the group of Sarcoma and were all mixed: in the Swine a small round- celled variety, with much hemorrhage; in the Lemur a round- celled and fibrous variety, rapidly growing; and in the Squirrel it was mostly of the large round-celled kind. 17. Under this heading are included animals which have died from exhaustion, due probably to depressed vitality from cold or darkness, or from inability to get or take food, as has been the case with many small reptiles. 18. In these cases there was very profound anemia with con- siderable blood-changes. It is most probable that these cases were all parasitic in origin, but no cause, parasitic or otherwise, could be found. In a Turtle-Dove the very rare condition of phagocytosis of the red corpuscles by the leucocytes was observed. 1910.] ON HYDROIDS AND NUDIBRANCHS OF BERMUDA. 137 4. Notes on the Hydroids and Nudibranchs of Bermuda *. By Prof. W. M. Smatiwoop, Syracuse University +. [Received November 15, 1909. ] (Text-figures 7-10.) The writer spent the month of January 1909 in Bermuda, studying at the Biological Station on Agar’s Island. The courtesy of the use of the Station was extended to me by the director, Professor E. L. Mark, to whom I express my thanks. The specific problem of research was an inquiry into the condition of the living nerve-cells of nudibranchs; but in addition some observations were made that may be worth recording. Hardly a day passed that one or more Awrelia were not seen. Most of the specimens were small and none showed mature gonads. Vast quantities of sargassum were blown on to the various islands, and on all of this the common summer hydroids were found. Specimens of Clytia simplex and some unidentified campanularians were repeatedly examined, but on none of them were -gonothece present. Aglaophenia minuta was taken the latter part of January with many empty gonosomes ; but other than this the hydroids on the sargassum did not show any signs of sexual activity. Lytocarpus philippinus was in a very active healthy condition during the month and showed plenty of vitality by forming numerous asexual branches, but no gonosomes were noted. Congdon (07) speaks of slight variations from Nutting’s descrip- tion, in that “the colony [is] shorter.” All of the colonies collected by us were at least eight inches high and some of them nearly a foot. They were taken in shallow water off Fairy-land Point. Eudendrium hargitti was taken at Hungry Bay the last week in January. ‘Two large colonies, about three inches high, were found; one of them was in fruit, the orange-coloured gonophores being very conspicuous. One new hydroid, which has been handed to Professor Hargitt for description, was found growing on Zoodbotryon pellucidus. The writer regretted very much that the weather was unfavourable for collecting in Castle Harbor, where further oppor- tunity would have been afforded to study the winter conditions of Pennaria and other hydroids. Curomoporis zeBRA Heilprin. (Text-fig. 7.) This is one of the largest nudibranchs of Bermuda. It was first described, briefly, by Heilprin (89. p. 187, pl. 15. figs. 3, 3a), as follows :—‘“Animal of the form typical of the genus; head portion considerably extended and expanded in motion; caudal * Contribution from the Bermuda Biological Station for Research, No. 18, and from the Zoological Laboratory of Syracuse University. + Communicated by Dr. P, Caatmers Mitcwert, M.A., D.Sc, F.RS 138 PROF. W. M. SMALLWOOD ON HYDROIDS [Jan. 18, portion moderately elongated; base flattened; mantle beaded immediately over the tail. “Color bright blue above, variously lined and streaked with light yellow ; on the dorsal surface the yellow markings are disposed in longitudinal wavy or nearly straight lines, one or more specially prominent lines along the dorso-lateral border. Sides of animal irregularly reticulated or angulated with yellow markings; under surface pale blue, bordered with faint yellow. Rhinophores deep indigo or black, the rhinophoral aperture bordered with yellow ; gills 12 or 13, black, bordered with yellow, and carrying blue cilia; under surface of head blue, with yellow spots. “ Length, when expanded, three and a half inches. Three specimens, dredged in about ten fathoms on the north side of Harrington Sound.” The few observations by Heilprin on the internal anatomy do not serve to distinguish this species from the other Chromodoride and so are omitted. He gives two rather generalized figures with but httle accurate detail. Other than the above, no description of this species has been made, so far as I have been able to determine. Bergh (92) questions whether C. zebra is a distinct species from C. villafranca, but this can not be settled until the anatomy has been thoroughly worked out; this will be done in a separate paper. The following observations on the external morphology add a number of facts to Heilprin’s description. Over fifty specimens were available for observation during the month, which gave ample opportunity to note a number of variations. The length of the body from the anterior tip of the mantle to the posterior end of the foot is 16cm. ‘This is the average length of the animals as they were crawling around in the aquaria. The body is much elongated and linear; it is thickest just anterior to the branchial plumes, becoming slightly depressed anteriorly. The mantle is rounded at each end and a little wider than the foot ; it is slightly broader in its anterior than in its posterior portion, and projects beyond the end of the tentacles. The foot is uniformly narrow and linear; it tapers off to a point posteriorly, but its anterior end is squarish with rounded corners. The ground-colour of the animal is blue. The foot is pale blue, but the intensity of the colour varies with different individuals. The margin and posterior tip are almost free from this ground- colour. The bottom of the foot is not modified by any other colour. The protrusible pharynx is likewise deeply coloured with a similar unmodified blue. This ground-colour of blue is not as conspicuous on the rest of the body, where there is a series of irregular streaks and a mottled effect produced by colours which range froma dark olive to orange. These markings are by no means the same in all individuals. In fact, of two dozen animals collected from the same spot at the same time, no two specimens were found to be alike. The dorsal margin of the foot is free 1910.] AND NUDIBRANCHS OF BERMUDA. 139 from the olive to orange colours, and the under edge of the mantle is generally so. The number of streaks and mottles is not constant. About 5 mm. back from the rhinophores and a little nearer the median plane, there are two oval spots of light blue, which are constant in position but not in shape nor in relation to the streaks. The tentacles are short, retractile, conical, and blue in colour. The rhinophores are perfoliate with 28 leaves in the clavus. The clavus is of a deep ultramarine blue, the deepest colour seen any- where on the animal. The rhinophores may be retracted within conspicuous collars, which have smooth margins. Chromodoris zebra Heilprin. V-ewed from the right side; the branchial rosette turned toward the observer. 2 natural size. The branchiz are from 12 to 14 in number; they are surrounded by a high sheath with a smooth margin, within which they are completely retractile. In the olive-coloured forms the branchize are often more deeply coloured than the mantle, and in such forms the backs of the plumes are slightly bronzed. The more orange-coloured individuals have light coloured branchiz, which are frequently lighter in colour than the mantle. The branchie when fully expanded are rosette-like in outline and extend beyond the kody. When in this expanded state, one readily notices an inner flesh-coloured collar that expands beyond the limits of the mantle-collar. The anal opening is subcentral, the ring formed by the bases of the branchie being open on the posterior and ventral margin. The tip of one or two of the branchie is seen to end in a minute division into two, three, or four parts. This is avery common characteristic, so that one hunts for some time before finding an animal which does not show it; only two such specimens were noticed. The gills occupy both sides of the plume as a series of about fifty leaves. On the ventral, posterior border of the mantle there are five or six white conical elevations, which produce the beaded eftect mentioned by Heilprin. The whitish colour is due to the presence of numerous globular structures, which turn pinkish in strong nitric acid. ‘They were not destroyed, nor was there any effervescence, in nitric or hydrochloric acids. These white conical papule are noticeable in the living animal, but become more conspicuous after the animal has died. ‘The mouth is circular. 140 PROF, W. M. SMALLWOOD ON HYDROIDS [Jan. 18, The genital opening is lateral and about one-third of the distance from the rhinophores to the branchie. It is noticeable as a slight prominence, which is blue in colour. The oviduct is protruded during oviposition and has the pale blue ground-colour. The deposition of the eggs does not seem to occur at any set time during the year. Mr. Mowbray has found eggs during every month of the year. and I secured a large quantity of them during January, 1909. The eggs are laid at any time during the day and often during the night. The external orifice of the oviduct is widely distended, a centimetre or more, and one can see the eggs within this opening for some distance, about 5 mm. The egg- mass (text-fig. 8) is in the form of a long, thick ribbon, often 150 mm. long and 15 mm. wide. When free from the animal, this ribbon tends to coil up, and it firmly adheres to the side of the aquarium by one of its edges. ‘Two animals were timed during a part of the act of deposition, and from this as a basis I should estimate that the complete process would take three hours. Text-fig. 8. Kgg-mass of Chromodoris zebra Heilprin. Seen obliquely. 4 natural size. An hour after the animal ceased laying, some of the eggs, but not all of them, showed two polar bodies. The eggs are laid in the jelly as a continuous string, which takes the form of a somewhat flattened spiral, so that when the broad face of the ribbon is viewed the string usually looks as though regularly folded back and forth across the ribbon. There are about one hundred eggs in a complete turn of the spiral, although this number is not constant. As there are from eighty to one hundred completeturns of the spiral, this would give from eight to ten thousand eggs to a single laying. It would be interesting to know how often each year they are capable of depositing such large numbers of eggs, but it is doubtful if this can be determined, as they are not hardy, soon dying even when placed in running water. It is probable that they come from the deeper water only to spawn, spending the rest of their time at some distance from shore. The egg are of a reddish-brown colour and develop slowly, as is shown by the fact that four and one-half hours after deposition they are still in the one-cell stage. In the first lot of Chromodoris zebra collected there were over thirty specimens. The variation in colour was marked; one specimen of especial interest escaped my attention for a couple of days. This individual on close inspection proved to be a kind of albino. In size, shape, and general habits, it was undoubtedly 1910. ] AND NUDIBRANCHS OF BERMUDA. 141 the same as the other individuals coliected at this time, but the bluish ground-colour was entirely wanting. ‘he following colour differences were conspicuous. The foot was white with no blotches or spots of any colour. The protrusible proboscis was entirely white. The rhinophores were of a light brown tipped with white. The collar of the branchial plumes showed an absence of colour, as did the back of each plume, so far as any ground-colour was concerned, a few spots of orange only remaining. The gills were colourless. The remainder of the body was streaked and mottled with a bright orange, but between these orange spots there was an entire absence of the usual ground-colour. Even ina preserved state, this albino can readily be distinguished from -specimens which have the usual ground-colour of blue. FACELINA AGART, sp.n. (Text-fig. 9.) It is impossible to be certain to which of the Eolidee this species belongs, because only a single specimen was found, and the differences between the several subdivisions are so slight that a critical study of the morphology of a new species is necessary before one can feel certain where to place it. This form resembles Facelina bostoniensis more than it does any other one of the Eolide that I have thus far examined; but F. bostoniensis is referred to by Bergh (92, pp. 36, 40) under the name Corphella as well as Yacelina. This seems to indicate that there is a con- siderable difference of opinion in reference to F/. bostoniensis, and the same is true of several other forms. As soon as I can obtain more animals of this species, I hope to work out its anatomy in a eritical manner, but until then I shall regard it as one of the Facelinide. This specimen was found under stones on the shores of Agar’s Island, on which the Bermuda Biological Laboratory is located; so it seems appropriate to give it the specific name agart. The body is long and slender—30 mm. long and 2 mm. wide. The rhinophores are club-shaped with conical tips, slightly con- tractile, and covered, except at the tip and base, with numerous small blunt tubercles. The presence and the shape of these tubercles on the rhinophores are a distinguishing characteristic of this form, and make one hesitate to place it in the genus Facelina, where the rhinophores are usually slender and perfoliate ; how- ever, this latter character is not a constant one. The head is rounded, narrow; the tentacles occupy the sides of the head, and are conical, sinall in diameter, and longer than the rhinophores. ‘Their surface is irregularly roughened. The foot is rounded anteriorly and bears a pair of distinct, angular, auricu- late processes, which at first are easily mistaken for a second pair of head-tentacles. They are the foot-tentacles. The foot gradually tapers behind to a sharp point, the least bit of which can be seen posterior to the waving branchie. The foot is colourless and wider than the body. The branchiz are numerous and arranged along each side of the 142 PROF. W. M. SMALLWOOD ON HYDROIDS [Jan. 18, body in several (six) more or less distinct groups. On the left side, lateral to the rhinophore, there are in the first group nine very small branchie. These are followed without any noticeable interval by twenty-one branchiz of larger and uniform size. These all arise from near the edge of the dorsum, but bend over so as to give the appearance of growing out of the middle as well. In the third group of the left side there are twenty-two branchie, part of which grow out of the middle of the back.

METADIAP TOMUS TRANSVAALENSIS. 1910.] FRESHWATER CRUSTACEA FROM 'THE TRANSVAAL. 149 Weber) * used to come into my tow-net, when dredging through the weeds; this was the only fish I came across, and I was told that no other existed there. J might also add, that an effort had been made to introduce a large species of Barbel but without success. Besides Lake Chrissie there are about a dozen other pans, none however approaching that lake in size. The larger pans are as a rule without reeds ; the smaller ones may be completely over- grown. In the case of the former, the bottom may be composed of sandstone with httle or no mud present; in the latter case, fine mud is always present, very often of some depth. Very few pans were at the time dry, but all of them, during certain seasons after droughts, dry up completely; most of them depend for their supply of water on rain-fall; others like Lake Chrissie are furthermore fed by small spruits. Generally speaking the water is somewhat brackish. As to local distribution, I found most species of Entomostraca in Lake Chrissie; but this result may be merely due to the fact that since I had not the time to dredge all the pans very thoroughly, I thought it best to pay most attention to Lake Chrissie and to visit others but once or tw ice. A feature of interest among this entomostracan fauna is, that out of the six species of Cypride here described, in five males and females were found in about the same proportion. No doubt this interesting fact is correlated with the frequent drying up of the pans, thus agreeing with the Cypride of South- West Africa as noticed by Wavra (11), and differing from their European freshwater representatives in which males occur so rarely that some species are known only by descriptions of females 7. The species collected throw some not altogether uninteresting light on recent theories of distribution, and tend to confirm these theories. This paper will, I think, have added some evidence in favour of those who contend that South Australian, Tasmanian, New Zealand, and South American forms have been independently derived, perhaps through some Antarctic continent, from those now found inhabiting South Africa; I refer especially to a paper recently read by Mr. “G. W. Smith (10). In this paper it is sug- gested that such forms as the freshwater Gammarids and Isopods ov the genus Lepidurus, being essentially Crustacea preferring a temperate or cold climate, found their way to South America, and the Bassian subregion of Australia (Prof. Baldwin Spencer), by spreading along the Andes and thence to Australia by some lost Antarctic continental connection. Now no forms, typical of these said regions, have as yet been described from South Africa ; no freshwater Gammarids or Isopods are known to * I am indebted to Mr. G. A. Boulenger, F.R.S., for the identification of this fish + R. Moniez (5) first alluded to male Ostracods in Algeria appearing regularly amongst those forms which in Europe propagate their species parthenogenetically. 150 THE HON. PAUL A. METHUEN ON [ Feb. 1, occur; in the family Apodide, Apus alone is represented ; among the Copepods we find rather a striking fauna: Boeckella is absent, and we find instead several genera some of which appear to be peculiar to South Africa; Crayfishes are absent from the spruits and rivers, the chief occupants appearing to be the river crabs and prawns. Of further interest is the great resemblance some of the forms found in the Transvaal bear to their European representatives ; in all cases where possible, their points of resemblance to particular European forms have been mentioned ; it is also interesting that Daphnia pulex, which was found in a dam near Pretoria, is in nearly every detail similar to the Daphnia pulex of Kuropean waters (vide Pl. XV. fig. 40). But to return for a moment to the Copepods. Including the Metadiaptomus of this paper, in all, four genera peculiar to South Africa have been determined. Of these the dominant genus Broteas (= Lovénula) appears to be the most widely distributed. Moreover, several species of Diaptomus have been described from South Africa, notably by Mrazek (6) from German West Africa. The genus Metadiaptomus resembles Adiaptomus, described by A. W. Cooper (2), in that the antennule possesses twenty-six segments instead of twenty-five as in Diaptomus; but a glance at Pl. XVI. fig. 46a, and Pl. XVIII. fig. 55, will show two further peculiarities ; (1) m that the antennal region of the thorax appears to be distinctly divided from the rest of the body; and (2) in the marked difference in the structure of the modified sixth pair of thoracic appendages from that of Diaptomus, especially in the male (vide text-fig. 11 6, p. 162). Summing up the question of distribution here discussed, it might be said briefly: (1) that the Hntomostraca here described show no relation whatever to Crustacea from the Bassian Region of Australia: (2) that they do show a certain approach, in some cases a marked resemblance, to Huropean forms ; (3) that, further, they have been evolved to a certain extent along lines of their own, showing considerable modifications which are not paralleled elsewhere. In conclusion I take this as an opportunity of expressing my gratitude to Dr. Gunning, of the Transvaal Museum, for his kind assistance and advice; and to Mr. G. W. Smith, who just before I left England suggested Lake Chrissie as likely to yield some interesting results, for the help and encouragement he has given me in preparing the following descriptions; and I feel, if there is anything in this paper of interest or value, it is due to his suggestions, Order OSTRACODA. Family CyPprip &. The classification of G. W. Miller (7) has been adopted for assigning to the Ostracods here described their systematic position. They are all five undoubtedly Cyprids having eight- segmented antennules which are provided with long and slender 1910. ] FRESHWATER CRUSTACEA FROM THE TRANSVAAL. 151 hairs. However, it has not been without some hesitation that they have all been placed in the genus Cypris. Miller gives as characteristic for this genus, that the third biting process of the maxillula has two claw-like bristles distinct from the others which may or may not be toothed (p. 51). This is so in the cases of Cypris gunningi, O. chrissiensis, and C. mastigophora, and possibly of C. tuberculata; but although the maxillula of C. spinosa possesses these toothed bristles, it has, in addition, two small ones of similar character. It was not considered expedient to create another genus for this species on that character and others mentioned below, nor yet a new sub-genus, so it has been placed temporarily in the genus Cypris. As. to the common relationship of these five species, it will be seen that whereas C. gunningi and C. chrissiensis are closely connected one with the other, C. spinosa and C’. tuberculata are aberrant, chiefly in the characters of the shell and of the maxillula. C. mastigophora undoubtedly conforms in many particulars to the subgenus Cypridopsis. Besides the new species, Cypris venusta (Vavra, loc. cit.) was found fairly plentifully in Lake Chrissie; the most notable feature of this Cyprid is the presence of peculiar marginal denticulations on the shell. Genus Cypris O. F. Miller. CYPRIS SPINOSA, sp.n. (Plates VIII., IX. & X. figs. 9-12.) Length 3°3 mm.; breadth 2°52 mm.; height 2°05 mm. External appearance : from the dor sal aspect, the shape of the body is roughly quadrilateral, the ventral margins of the shell being expanded horizontally into wings. From the dorsal posterior region of each shell spring two long stout spines directed backwards. The anterior dorsal border of each valve is furnished with eight small spines; between the fourth and last spines are regular groups of bristles. The lateral expanded wings of the valves are much flattened and are produced along their posterior border into four or five spine-like processes ; on the rounded surface of each shell there are two small prominences present. The general colour is mottled umber ; specimens found in Lake Chrissie were greenish. Appendages. —The elght-jointed antennule resembles that of a typical Cypris. The antenna consists of four joints: the second joint is furnished with five long swimming-hairs which reach to the end of the claws; the claws are longer than the terminal segments; just behind the claws are found three fine bristles. The second joint is provided dorsally and ventrally with rows of small fine hairs which vary somewhat in size and arrangement. The mandible resembles very closely that of Hurycypris juin a as described by Claus (1). 152 THE HON, PAUL A. METHUEN ON [ Feb. 1, The maxillula consists of a branchial appendage, a palp, and three biting processes. The branchial plate is provided with twenty-eight plumose rays. The palp is two-jointed; the distal joint bears five smooth bristles, and the proximal joint one short and six long bristles, also smooth. The third biting process carries terminally two simple bristles and two large and two smaller foliaceous sete ; subterminally there are three plumose bristles and a short smooth one. The second biting process carries terminally nine bristles, some simple, some plumose, and two foliaceous sete. The first bitmg process is provided with seven bristles, some of which are simple, the others plumose, and in addition three foliaceous sete. The maxilla is precisely similar to that of Hurycypris pubera figured by Claus except for the presence of an inconspicuous group of hairs midway between the endopodite and the biting process. The clasping organ attached to this appendage in the male consists of a straight proximal and a curved terminal segment; on the inner side and situated at the distal base of the former piece are two spines, one considerably larger than the other, and the terminal segment ends in a sharp spine. The structure of this clasping organ is different on each side ; on one side the proximal joint is shorter, and the distal joint which is sharply recurved is slenderer than is the case in the opposed portion. On the other side the distal joint is stout and sharply recurved. The fourth post-oral limb resembles that of the subgenus Eurycypris 11 having the second and third segments fused, the internal border of the first joint bearing groups of short bristles which appear to spring from peculiar chitinous thickenings. The terminal serrated claw is somewhat longer than the fused second and third joints, and at its base springs a short serrated spine with a V-shaped base. The fifth post-oral limb, the cleaning-foot, closely resembles that of Hurycypris pubera. The caudal rami are a pair of slender, slightly curved rods, each carrying terminally a serrated seta which is twice as long as the outer seta inserted just proximal to its base; this latter is also serrated. They resemble closely those of Hurycypris pubera. The copulatory organ of the male resembles in general shape that of Cyprinoius incongruens described by Miller. The outer branch of the outer process is foot-shaped, the inner branch being in the form of a curved spine; the outer border has a large projection to receive the coils of the vas deferens. Locality. I obtained a great number of specimens in the littoral water of a small reed-pan near Chrissie and found two or three specimens in Lake Chrissie itself. Remarks.—This species is remarkable in the peculiar shape of the shell and especially in the presence of the remarkable spinous processes which have been described. The large size of this species is also to be noted. The 1910. ] FRESHWATER CRUSTACEA FROM THE TRANSVAAL, 153 appendages agree closely with the genus Cypris and especially with the subgenus Hurycypris ; from this subgenus it differs in certain characters, the most important of which is the presence of a greater number of foliaceous sete on the biting processes of the maxilla. C. puberoides as described by Vavra (loc. cit.) from German South-West Africa, is not unlike this species, chiefly in the character of the flattened shell, the penis and copulatory styles of the maxilla, and in the character of the antenna, which carries five claws. CYPRIS GUNNINGI, sp. n. (PI. X. fig. 13; Pl. XI. figs. 14a, 6, 5 Ge, WG 3 TEU, LEE DSU artes 3} 79 (8 Tel OV snips 318),)) Length 1°30 mm.; height, greatest ‘74 mm., at centre *68 mm. External appearance : a lateral view of this animal shows it to be considerably longer than deep, the ratio of the length to the depth being as 2:1. The whole surface of the bivalve shell is covered with hairs of moderate length; they are longest on the ventral marginal edge, becoming shorter near and disappearing on the hinge-line; on the ventral inner margin of the shell, denticulations are present, which become very minute as they approach the dorsal hinge-line; these denticulations do not project beyond the outer margin of the shell. Appendages.-—The antennule is typical of the genus Cypris. The antenna has the terminal segment considerably thinner than in the foregoing species and the number and length of the sete and hairs differ slightly; but two important distinctions are found on the second segment: (1) the swimming-hairs project considerably beyond the claws, a characteristic of the subgenus Cypridopsis; (2) a row of movable (?) denticulations is developed on that part of the distal marginal edge of the second segment which is opposed to the proximal portion of the third joint (Pl. XI. fig. 146). The exact function of these tooth-like processes is not perhaps at once clear; but it may be, that being so placed in conjunction with the distal segment they serve the purpose of locking the second and third segments together in a straight line, thus strengthening the whole ap- pendage for swimming. It is to be noticed that when the appendage is flexed at this point, the denticulations are flexed also. When, however, the third joint is flexed back into a straight line with the second, these processes would be brought up into the same straight line and so form a strong support to the two segments or actually lock them together. The mandible is stouter than in C. spinosa; the two stout hairs on the inner part of the gnathobase are much shorter. The palp differs slightly in that the sete on the terminal segment are not serrated, the stout plumose sete on the fourth segment ave much shorter, and the palp futhermore differs from that of C. spinosa in the number and character of the sete on the inner margin of the first and second segments. 154 THE HON. PAUL A, METHUEN ON [ Feb. 1, The maxillula: the forward-directed palp bears six fairly long bristles, two of which are plumose and one short. The distal joint bears three large and three small bristles, besides a number of hairs set close behind the base of the bristles, and one stout hair on the inner margin. The third biting process is peculiar. Besides the normal foliaceous sete and bristles characteristic of the genus, the process 1s provided with a short seta which is armed with a number of hairs springing from its distal extremity and set at right angles to this seta: close but external to this structure is another seta considerably larger and thicker whence spring several short bristles. The other two biting processes, which are without the foliaceous structures found in C’. spinosa, bear a number of stout smooth bristles. The maxilla: the exopodite has fourteen plumose hairs as against thirteen present in C. spinosa; the plumose median seta of the endopodite is very long. The male accessory copulatory processes are, on the whole, stout; the distal joint of each differs considerably, one being slender, the other pear-shaped. The fourth post-oral appendage: the third segment distinctly consists of two pieces; two rows of minute bristles border the distal margin of the fourth and fifth segments; the arrange- ment of the terminal sete of the fourth segment differs from that found in C. spinosa. The fifth post-oral appendage: the median seta of the third segment is longer than in C. spinosa; otherwise similar. The caudal furca: the rami are generally stouter than in C'. spinosa ; distally a double row of serrations are borne along half their lengths; the two large distal processes on each ramus are relatively stout and short. Locality. Found abundantly in littoral water of Lake Chrissie, CYPRIS CHRISSIENSIS, sp. n. (Pl. XI. fig. 16; Pl. XIV. figs. 34, 308) Pl XV, fig. 37.) Length °73 mm.; height -44 mm. External appearance: in proportion to its depth this species is not so long as C. gunningi, the ratio of length to depth being as 1:7:1; correlated with this comparative decrease in length or increase in depth are two factors, namely, that the convexity of the dorsal surface of the body and a concavity in the ventral margins of the shell are more evident. In nearly all other respects this species resembles C. gunningt. It also bears a great resemblance to Cyprinotus congener ( Vavra, loc. cit.), especially in the character of the accessory copulatory processes of the maxille, The general shape of the body and of the gnathobase of the mandible, and the structure of the accessory maxillary copulatory organs, are sufficient evidence that this is not a young form of C. gunningi; further, more than one female was found with ripe ova and introduced spermatophores, which leaves no doubt on the subject. 1910.] | FRESHWATER CRUSTACEA FROM THE TRANSVAAL. 155 ia eeaeaitt —All the appendages are similar to those of '. chrissiensis except the following :— The mandible, which is somewhat slimmer. The fifth post-oral appendage: the terminal bristle is as long as the third segment. The median seta of the third segment and terminal seta of the second segment are short as in C. mastigophora. The maxillary accessory copulatory structures are longer and thinner than in C. gunningi. The basal joint of one is very thick and stout, but of the other thin and long. CMERIS MASIIGOPHORA, (sp. mn. (Pie OX tte nS) bls Sxenve Hes ai Pl XeV. fis, 38.) Length -52 mm.; height °25 mm. External appearance : viewed from the side the ratio of the length to the depth is roughly as 2:1. The hind-end tapers considerably; the fore- part ends bluntly. Fairly long hairs cover the surface and margins of the shell; denticulations are absent. Appendages.—The antennule is typical of the genus Cypris. The antenna: the swimming hairs extend beyond the claws. The mandible: the disposition and number of sete and bristles on the pulp are different from such as are found in the foregoing species. The terminal joint bears two large stout bristles and one small seta; the third segment is furnished with one large plumose bristle, and four sete, three plumose, on the imner margin; on the external surface one short and three long sete, and a group of hairs just behind these structures. he third segment of the palp bears on the external margin two long smooth setee, and on the internal margin five stout pectinose bristles. The second segment is provided on the internal surface with three thick bristles, two of which are pectinose. The maxillula: the terminal bristles of the palp are stouter than in C. gunningi. On the third biting process, in addition to the two foliaceous bristles, a number of fine setze are developed below the extremity. Foliaceous bristles on the other biting processes are absent. The maxilla does not differ from C. gunning. The fourth post-oral appendage: the third segment consists of two pieces; the appendage is practically similar to that of C. gunningi, except for the presence of additional sete at the terminal end of the fifth segment and in the arrangement of some minute hairs about the second segment. The fifth post-oral appendage: the median seta on the third and the end seta on the second segment are much shorter than in C. spinosa; otherwise similar in structure. The caudal furea differs from that of any of the other Cypride described here in that the rami consist of long thin whip-like processes with one short seta at the base, a character peculiar to the subgenus Cypridopsis. Remarks.—This species was comparatively rare ; unfortunately 156 THE HON. PAUL A. METHUEN ON [ Feb. 1, no males were taken. It was found with the other Cypride in Lake Chrissie in the shallow marginal parts of the lake. CYPRIS TUBERCULATA, sp. n. (PI. XIII. figs. 24-28, & Pl. XIV. figs. 29, 30, 33.) Length 1:9 mm. Height, anterior portion 1:65 mm., central 1:50 mm., and posterior 1:53 mm. External appearance: the shell has rather an exceptional appearance. It is covered with tubercles and short spines ; the arrangement of these processes in no way resembles that found in (. spinosa; moreover, those parts not bearing tubercles or spines have everywhere smail indentations, giving the appearance of beaten copper. The fore-part of the shell bears a few hairs irregularly arranged. The marginal edge is provided with hairs along most of its length. From tne side, the outline of the shell is seen to have a slight anterior prolongation. Appendages.—The antennule is typical of the family Cypride. The antenna: the swimming-hairs do not extend beyond the bristles of the distal segment. The arrangement of the minute hairs on the second and third joints resembles that found in C’. spinosa, but differs chiefly in the absence of hairs just behind the basal attachment of the swimming process on the second joint. Denticulations, as in C. gunningi, found on third joint. Distally only three curved serrated sete are present. The mandibles: an external serrated seta is present on the gnathobase ; a comb-like structure is found on one of the external biting lobes of the same. The palp is provided with a very strong plumose bristle which is conspicuously larger than any of the other. bristles and seta which it has in addition; the structure as a whole bears most resemblance to that of C. gunning?. The maxillula from the point of view of classification is of most importance, in that no foliaceous hairs are present on the biting processes, although the two large bristles characteristic of the genus are present. The first biting process is provided roughly with a dozen and a half bristles, all smooth save two which are longer than the rest and serrated; at the basal extremity on the inner surface of this process arise two hairy bristles. The second biting process does not differ much from the first; but the long serrated bristles of the first are in this case absent. The third biting process is remarkable in possessing no foliaceous sete. The two stout bristles shown in fig. 27 represent the foliaceous sete found in the genus Cypris, the small grooves noticeable on these structures possibly indicating the remains of the reduced “pinne.” This same character is also found in C. virens described and figured by Claus (1), but in this case the bristles are smooth. The palp resembles that of C. guuningi, the only difference between the two being that the short hair on the first segment is replaced by a longish one. The maxilla: the exopodite is furnished with fifteen stout 1910. | FRESHWATER CRUSTACEA FROM THE TRANSVAAL, 157 bristles; the first two bristles, which are short and thick, bear distally a number of small sete; the third is large and hairy ; the fourth and fifth are smooth; the sixth is short and serrated. Small hairs are found to cover the ventral surface and other parts of the appendage (Pl. XIII. fig. 28). The fourth post-oral appendage : the third and fourth segments are distinct: the arrangement of bristles and hairs resembles that of C. gunning. The fifth post-oral appendage: the bristle and curved seta of the distal segment are comparatively long. Each ramus of the caudal furca bears along nearly the whole of its inner edge a row of seta and distally the four characteristic bristles. Remarks.—This species was found not uncommonly, together with the other Ostracods described, in the shallow littoral water of Lake Chrissie. Order CLADOCERA. Family Lyncrip #. Genus Lerypiera Kurz. LEYDIGIA TRISPINOSA, sp. n. (PI. XVI. fig. 43.) Length 1:27 mm.; height °735 mm. This species resembles, in the general shape of the body and character of the telson, Leydigia acanthocercoides described by Lilljeborg (3) and figured on pl. Ixxi. fig. 4. The head is small. The posterior part of the carapace has the appearance of having been “pulled out” in a ventro-posterior direction ; its ventral margin is provided with a row of stout hairs. The two large terminal spines of the telson are serrated; each bears at its base one small spine and a group of small hairs: anterior to these are eight pairs of fairly large stout spines; at the base of each arise two small ones of which the most internal is the smaller; the arrangement is therefore characteristically triple ; in front of these spines, again, lie eight pairs of small spurs each with its group of setz placed in an anterior position ; slightly external to these, a row of fine sete, which runs nearly the whole length of the body, is noticeable. Locality. Shallow littoral water of Lake Chrissie. Genus CHyporus Leach. CHYDORUS CAROLINA, sp. n. (Pl XVI. figs. 44a, 6.) Length -47 mm.; height 37 mm. Body rotund; posterior angle distinct, without spine or process; the ventral margin of the shell has a fringe of spines; the rostrum, which is long and pointed, projects considerably beyond the end of both pairs of antenne ; no striations visible on the carapace ; the arrangement of bristles on the telson is somewhat unusual. Found in same locality as preceding species. 158 THE HON. PAUL A. METHUEN ON [ Feb. 1, Family DAPHNIID 4S. Genus SIMOCEPHALUS Scheedler. SIMOCEPHALUS CORNIGER, sp. n. (PI. XV. fig. 41 & Pl. XVI. fig. 42.) Length 2°34 mm.; height 1°76 mm. Body sub-ovate; head region defined from thorax by a dorsal notch; the shape of the body resembles that of S. vetewlus described by Lilljeborg (oc. cit.) and figured on pl. xxiv. fig. 8; the ventral margin of the carapace is provided with a row of minute spines reaching back- wards from near the head along a considerable portion of its length ; through three quarters of this length but slightly internal to the row of spines, lies a line of closely-set stiff hairs ; posterior to these structures, the carapace is furnished with a single row of short stout spines which reach almost as far as the posterior limit of the ventral margin of the body; they are smallest at the posterior region of the carapace. Nearly the whole surface of the body is covered with minute prickles. The carapace is striated (only a portion is shown striated in fig. 41). The two large claws of the telson are serrated, and at the base of each lies a group of small sete. Of the other spines the largest are curiously bent; each carries a group of sete; further, groups of minute hairs, generally five or six to each group, are produced on the inner part of the telson; their limits are best realized on reference to tig. 42. Locality. This species was found in Lake Chrissie, but oceurs more abundantly in a little reed-pan three miles east of Chrissie. Genus Dapunta O. F. Miiller. DAPHNIA PULEX. (PI. XV. figs. 40 a-c.) A few adult forms were found in Lake Chrissie, and a quantity of young in a dam near Erasmus’ Farm, Pretoria. As already mentioned this Daphnia appears to be similar to the EKuropean form. There is one point in which it differs from D. pulex, but it is so insignificant, that it was not thought desirable to give this species specific distinction from D. pulex. The point is, that caudal styles and dorsal processes just in front, which project into the brood-chamber, are quite smooth. This South African form was not found to differ from the European representative in any other detail. DAPHNIA GIBBA, sp. n. (Pl. XV. figs. 39 a, b.) Length with tail6mm. Body rotund, but dorsal part of head and neck region enlarged to form a hump. Carapace striated. Tail, which is fairly long, covered with small spines which run a short way up the carapace and also ventrally extend along the margins of the carapace as far as the head. 1910. | FPRESIIWATER CRUSTACEA FROM THE TRANSVAAL. 159 The distal claws of the telson are pectinate, and are provided with small sete. The pectinate processes are divided into three lots, each arranged in a semi-lunar form (vide fig. 39 6). Anterior to these claws, the telson is fringed by a number of stout bristles ; internal to this fringe, along half its length, groups of minute setze are found. On following the course of this fringe of bristles, it is found that they end gradually, passing internally into three or four rows. Still further, a number of minute sete are found arranged in parallel tiers which run at right angles to the sagittal plane of the telson. The caudal styles are partly plumose; the dorsal part of the telson extending from these styles, so as to include the finger-like processes which project into the brood-pouch, is hairy. Locality. This striking and beautiful Daphnia was found fairly abundantly in Lake Chrissie and in some of the other larger pans. Order COPEPODA. In all, four species of Copepoda were taken. But it is an interesting fact that although the two species described below were found in great quantities, only one specimen of Cyclops and one specimen of Harpactid were taken. The latter may have easily been overlooked on account of its small size, but the scarcity of Cyclops is not a little remarkable. Unfortunately the Cyclops was not well enough preserved to allow identification. Family CENTROPAGIDS. Genus Broreas Lovén = Lovénula Schmeil. Broreas FALCIFER Lovén = Lovénula falcifera Schmeil. (Pl. XVI. figs. 45 a, 6b.) Length of male 4mm.; of female 3-6 mm. In nearly every detail this species is identical with Broteas falcifer described by G. O. Sars (8) from the Cape Peninsula; a few points of © structural difference are found : (1) in the length of the antennules, which when flexed back in line with the body reach as far as the proximal part of the caudal rami; (2) in the fact that the three outer bristles on the right furcal ramus in the male, instead of being smooth, as in the case of the species described and figured by G. O. Sars, are serrated on the inner side only in the case of the two internal and on each side in the case of the third bristle internal to these two; (3) in that the small fine bristle on each ramus, which occupies an internal position, slightly removed from the fringe of stout bristles, is somewhat longer than in B. falcifer. The caudal rami are asymmetrical. It is considered that this Centropagid is no more than a local variety of the Cape form and has not therefore been given specific distinction. Abundant in the larger pans. 160 THE HON, PAUL A, METHUEN ON (Feb, 1, Genus MErADIAPTOMUS (gen. n.). Diagnosis. Both antennules of female and left of male consist of twenty-six segments. Proliferation to form this extra joint has not apparently taken place in the same manner as in Adiaptomus judging from the explanation and figure given by A. W. Cooper (loc. cit.). In the sixth pair of thoracic limbs in the male, the exopodite of the right appendage is three-jointed ; the basipodite is much enlarged on the internal surface to form a double cushion. The first joint of the two-jointed exopodite of the left leg carries a large curved claw, and distally two cushion-like processes are present. An endopodite to this left appendage appears to be wanting, but it may be present in a very reduced condition. In other respects like the genus Diaptomus. METADIAPTOMUS TRANSVAALENSIS, Sp. n. (Pl. XVI. figs. 46 a-c, & Pls. XVIL & XVIII.) Description of female.—Length of cephalothorax 1-25 mm.; of abdomen including furcal bristles °7 mm.: of antennule 1:27 mm. Body subcylindrical, the greatest breadth at the junction of the third and fourth segments; the anterior portion of the body shaped like the nose of a bullet; the posterior part tapers slightly. The cephalothorax is composed of six distinct segments, the antennal region being distinctly divided from the rest of the body ; the sixth segment bears projecting angular corners on its marginal lobes; these corners do not seem to represent another segment. The antennules when flexed back in line with the body do not extend beyond the limits of the cephalothorax. The abdomen consists of three distinct segments and the caudal rami. Description of male.—Length of cephalothorax *8 mm.; of abdomen, as for female, -45 mm.; of left antennule -86 mm. The great difference of size between the male and female is to be remarked upon. In general shape however and in its appendages it resembles the female. The abdomen consists of five segments and the caudal rami. The right antennule is geniculated. Appendages.—The descriptions and drawings of the appendages have been taken in nearly all cases from females. The antennules of the female and the left one of the male are made up of twenty-six distinct segments, a feature of Adiaptomus (see introduction p. 150). It is to be noticed, however, that whereas the proximal spine on the antennuie of a female Adiaptomus occurs on the third segment, in that of Wetadiaptomus it occurs on the second. From this evidence alone, it is concluded that proliferation to form this additional segment has not taken place in the same area or rather in the same way as in Adiaptomus as explained by A. W. Cooper (loc. cit. p. 101 and figs. 5, 5a). Now, from the sudden change of length exhibited in segments twelve and thirteen, it is tentatively suggested that proliferation may have taken place from a segment once representing segments eleven and twelve (vide Pl. XVII. fig. 47). This explanation 1910. | FRESHWATER CRUSTACEA FROM 'THE TRANSVAAL, 161 is put forward with all the more hesitation, seeing, first, that it may be merely superficial, and secondly, ‘that the generally accepted view is, that proliferation takes place from the pr. oximal segment, which is in this case together with the second seement admittedly short in comparison ih that of the antennule of other Centropagide. Ten xsthetes were found on the female antennule (they are coloured blue in the figure). The spines from segment fifteen onwards are finely serrated. On segments three to nine marginal groups of small setze are borne on the side other than that bearing spines and esthetes: on the same side, and situated at the distal extremity of each segment from eight to thirteen, is‘a group of minute sete. The male geniculated amtennule consists of the normal twenty-three joints. The antenna is very much like that of Diaptomus castor as figured by Schmeil (9): the exopodite consists of eight joints instead of seven ; all the joints except the third and eighth bear one bristle each ; "the third joint has two bristles and ‘he eighth is provided with three long distal hairs and a much shorter proximal: the terminal joint) of the endopodite has two lobes, one bearing nine prominent sete, the other seven and a few inconspicuous hairs marginally at the base of the long seta lying opposite the exopodite. A row of eight small tere is placed distally near the external marginal edge of the second joint of the endopodite: the basipodite is “provided internally with one stout bristle. The mandibie: the gnathobase is stout and broad at the base, but half-way between the basal tubercles and the point of insertion of the palp, there is a marked ‘‘ neck.” The basipodite of the palp bears four bristles, two sete, one serrated and one smooth: the endopodite is two-jointed : a lobe is present on the proximal joint which bears four smooth bristles ; the distal segment carries seven long smooth hairs: in addition, on the outer margin of this distal segment are developed small sete which extend partly along the base of the terminal hairs. The exopodite appears to be four-jointed ; the distal segment is to all appearances single, and bears three long hairs; the other segments each carry one long hair springing from the internal margin. The maxillula (fig. 50) and maxilla (fig. 51) have nothing remarkable apart from what these appendages in Diaptomus possess. In the mavxillula, the first endite of the first basal joint bears ten stout and Ses finer bristles; the second endite has four bristles; the third endite has three; the first exite is provided with nine large bristles and the second exite with ons; the second basal joint and its endite together carry fourteen bristles, The maxilla is very like that of Diaptomus castor, but the third and fourth exites have two bristles each instead of three, and the fifth exite has four bristles instead of three. The first thoracic appendage or maxilliped is in the main like that of D. castor but is quite different from that of Adiaptomus. _The.second segment calls for special description, Dis'ally, on the Proc. Zoo. Soc.—1910, No. XI. ll 162 THE HON. PAUL A. METHUEN ON [ Feb. 1 inner margin three bristles are found, of which the proximal is setaceous; between this bristle and the joint of the first and second segments there is a close-set row of fine stiff bristles, in the form of a long comb, placed just internal to the inner margin of the joint which is itself partly frimged with fine hairs ; occupying the centre of the surface of this same segment is a mass of fine long hairs set in the long axis of the same and occupying about a third of its length. — The thoracic limbs (figs. 53 & 54) used for swimming are like those of a typical Diaptomus; but the modified sixth pair is sufficient to show the marked aberrancy of this species from Diaptomus or Text-fig. 11.

For convenience sake, the sixth pair of thoracic appendages of the male of Diaptomus castor, of Adiaptomus natalensis, and of the new species now under discussion are here figured side by side for comparison, since it is thought that the character of these limbs is of the greatest importance for classification (vide text-fig. 11 4, B, C). The whole organ is seen to consist of a pair of asymmetrical limbs, 1910. | FRESHWATER CRUSTACEA FROM THE TRANSVAAL. 163 the right considerably larger than the left and armed with a long terminal claw serrated on the inner side. This claw is borne by the exopodite, which consists of three segments ; the distal one is small, bearing, besides the long claw, a small protuberance or knob on its outer margin ; the second segment, which has a short spine terminally, is large; the endopodite is two-jointed; the distal joint is much shorter than the proximal and is armed with about: four fine sete terminally: between the endopodite and exopodite arises, apparently from the basipodite, a conspicuous thorn. The basipodite itself is somewhat peculiar; it has a rounded inner face bearing a double cushion, an inner part furnished with a row of short curved spines, and an outer part with a row of digitiform processes. Left limb: the distal basal . joint bears a bristle on its external surface and in addition an exopodite, but no signs of a endopodite, unless a small knob on its inner edge be taken as the remains of such. The structure of the exopodite is not very clear; but the following points have been made out, namely : a long proximal curved claw serrated along its inner margin, a cushion with serrated margin which is produced externally and distally into ashort curved spine, a second distal cushion smaller than the proximal one, bearing two rows of prickles. In the female this pair of limbs is in the main like that of Diaptomus; however, the first basal joint has no spines; the second basal joint is as thick as it is long; both endopodite and exopodite are present: the endopodite consists of one joint only; internally it bears two very small spines some distance apart, and terminally two bristles : the exopodite is two-jointed ; the distal segment carries two spines, and is produced into a serrated claw; the middle spine has further a small bristle and two or three minute hairs on its inner margin. The caudal furca are asymmetrical in both sexes, the left one being longer in each case. Five stout plumose bristles are present, and one small slender one which is smooth. Locality. Very abundant in Lake Chrissie and in the pans generally. Family HARPACTICIDA, Genus CANTHOCAMPTUS. CANTHOCAMPTUS 2 The one specimen obtained, which was very small, was unfor- tunately lost in attempting to macerate it. However, before this happened, it had been determined that it belonged undoubtedly to the genus Canthocamptus and closely resembled Canthocamptus finnt,as described and figured by Prof. G. C. Bourne (2a) from the neighbourhood of Zanzibar. This specimen from Chrissie was a female and was remarkable in having asymmetrical caudal styles ; a text-figure of these is inserted, and it will be seen that the right style is peculiarly bent and fashioned. This may be merely an abnormality, but the process was certainly intact. In the general l= 164 THE HON. PAUL A. METHUEN ON [ Feb. 1, shape, the animal was seen to be comparatively broad and short. The left caudal style was rather more than two-thirds as long as the body. Text-fig. 12.

Littoral Marine Fauna : Kerimba Archipelago, Portuguese Hast Africa. Collected by James J. Simpson, M.A., B.Sc., University of Aberdzen, September 1907— May 1908: HonornurtoipEa. . By JosEpH PrARson, D.Sce., F.L.8., Demonstrator and Assistant Lecturer in Tolley , University of Liverpool.* [Received November 23, 1909.] (Text-figures 13-17.) IT am indebted to Mr. James Simpson for the opportunity of making an examination of the Holothurians collected by him in Portuguese East Africa. The collection consists of twenty-one species most of which do not offer any points of special interest. Cucumaria turbinata is recorded for the third time. It was first obtained by Hutton in New Zealand, who gave an unsatisfactory description of the species. Professor Herdman also obtained it from Ceylon, and a full account of the species was given by me in the report on the Ceylon Holothurians (29)t. The form described by Théel as Colochirus violaceus is represented by two specimens in the col- lection. For reasons which I shall give later, I think it necessary to establish a new genus for this species. The following is a list of the species represented in the collection :— Synapta grisea Semper.

There are fourteen digitate tentacles, each being about 25 mm. long. Owing to the bad condition of the specimen it is difticult to say whether the digits of the tentacles are webbed. There appears to be very little difference between Synapta 1910.] FROM KERIMBA ARCHIPELAGO. 169 grisea and Synapta glabra. The spicules and the calcareous ring are very similar in both species. The calcareous ring consists of fifteen pieces. Hach of the five radial pieces has a broad anterior prolongation which is perforated by asmall hole.

I have already given a ful] description of this species in the report on the Ceylon Holothurioidea (29). In the present specimen the body has not the same shape as in the Ceylon specimen. It is evidently in a contracted condition so that the tapering anterior end which was characteristic of the Ceylon specimen is not shown. The whole of the body has a brown colour. The pedicels are black and are arranged in five double rows at both ends of the body. In the central region the tube-feet also spread over the inter-ambulacra and are more numerous on the ventral surface. The tentacles are absent. There is one Polian vesicle and the stone-canal. There are two respiratory trees (see text-fig. 13, eel): In addition to the deposits in the general integument which have been already described in the Ceylon Report, there are well- deveioped tables in the pedicels. These tables are long and narrow and are prolonged into two arms (text-fig. 14 A, p. 171). In the centre are four holes and at the end of each arm there are two or three holes (text-fig.14 B). From the centre of the table arises a short tower having one cross-beam and being surmounted by a few 170 DR. J. PEARSON ON MARINE FAUNA [Feb. 1, teeth. In addition to these tables there are a few perforated plates (text-fig. 14 C) and also numerous miliary granules similar to those present in Synapta (text-fig. 14 D). Text-fig. 13.

When the latter specimen first came into my hands the colouring was very decided, but in the course of a few months the colour has almost entireiy disappeared, owing probably to the action of light and the effect of the preservative. Externally the specimens agree with Théel’s description. There are no pedicels on the bivium and those on the trivium are confined to three definite rows. Very few papill are shown 172 DR. J. PEARSON ON MARINE FAUNA [ Feb. 1, in the specimens under examination. In the ‘Challenger’ specimen the papille were very obvious. There are nine arborescent tentacles in the larger specimen and ten in the other specimen. All the tentacles are about the same size. There are five ill-defined calcareous teeth around the anus. The calcareous ring has no posterior prolongations. There is one large Polian vesicle—28 mm. long—and one stone-canal. There are five well-developed retractor muscles extending from the calcareous ring to the body-wall. They are attached to the latter about half-way down the body. The respiratory trees are well developed. The alimentary canal is large and the reproductive organs are very large and consist of two bundles. Théel gives drawings of the whole animal, of the spicules and the calcareous ring. The spicules are few in number and agree with Théel’s figures. Length of buttons 63 »; breadth 55 p. As Théel and Koehler have pointed out, this species differs in a marked manner from the other species of the genus Colochirus. After a careful examination I have decided to establish a new genus for this form. Undoubtedly it does not possess any of the outstanding features of the genus Colochirus. The body is not quadrangular ; the anterior and posterior ends of the body are not pentagonal; the mouth is not surrounded by five valves; and the two ventral tentacles are not smaller than the rest. The deposits are few in number and unlike those of Colochirus. It agrees with Colochirus (1) in having three rows of pedicels on the trivium and only papille on the bivium, (2) in being a Dendrochirote having a calcareous ring without posterior prolongation. : General distribution. ‘Challenger’ St. 203, 11° 6’ N., 123° 9’ E.

By JosEpH Prarson, D.Sc., F.L.S8., Demonstrator and Assistant Lecturer in Zoology, University of Liverpool *. [ Received November 23, 1909. j (Text-figures 18-21.) Owing to the kindness of Mr. Simpson, I have had an oppor- tunity of examining the collection of Holothurians obtained by him and Mr. Rudmose-Brown from the Mergui Archipelago. This collection, which comprises fourteen species, is typical of the Indian Ocean. There are no new species to record, andI have noted no points of special interest with the exception of the occurrence of Thyone fusus var. papuensis. This form, which differs only from Thyone fusus in the large size of the calcareous ring, is interesting because of its distribution. The latter species is distinctly northern in its distribution and occurs in the cold waters of N.W. Europe. The variety papuensis has been obtained only from tropical seas, once by the ‘ Challenger’ in the Torres Straits, twice by Prof. Herdman off Ceylon, and it is also represented in the present collection. The following is a list of species in the collection : Cucumaria imbricata Semper. Cucumaria sempert Bell. Colochirus inornatus von Marenzeller. Colochirus cucunis Semper.

Thyone fusus, var. papuensis Théel, 1886 (15); Pearson, 1903 (21). One specimen from Station XXXII. S8.W. of Domel Is. Total length 25 mm.; greatest width 12 mm. This specimen has a characteristic appearance, being broad in the middle and becoming suddenly much narrower at the anterior and posterior extremities. Externally it resembles in a marked degree the northern form Zhyone fusus. Of the four recorded specimens of the above variety, I have had an opportunity of examining three, and I find that the only important difference between the variety and the parent species is in the nature of the calcareous ring. In both cases the shape is identical, but the ring is much larger in the variety than in Thyone fusus. In the specimen under examination the calcareous ring has a length of 12 mm.,7.e. half the length of the body. In aspecimen of Zhyone Jusus examined by Théel, the calcareous ring was only one-fifth the length of the body, and in a specimen I have examined the ring was even shorter. The deposits agree with Théel’s description, and appear to be very similar to the deposits of Thyone fusus. In the Ceylon specimens examined by me (21), there were tables scattered throughout the general integument as well as the deposits in the pedicels. In the Mergui specimen there are practically no deposits in the general integument, but in the pedicels there are tables similar to those described by Théel, and resembling those found in the pedicels of Thyone fusus.

The hard integument due to the closely-packed spicules is characteristic of this species. In the Ceylon Report I described plate-like spicules in addition to the deposits described by Théel and figured by Bell. A more detailed examination proves that these additional spicules have not the simple structure indicated by me in the Ceylon Report. In that report I described them as “plates having more than four holes and having short spines on the surface.” That is the appearance presented from above, but in side view it is seen that from the centre of the large plate there arises an irregular massive superstructure which bears numerous spines (text- fig. 20 A).

In addition to the small peculiar spicules, described by Théel as being ‘‘ acorn-shaped,” and which are very numerous, there are present delicate perforated plates which appear not to have been noticed hitherto.

It is to be remembered, however, that in some cases which at one time were believed to constitute examples of “ parthenogenetic” reproduction, males have been found to exist ; and it is possible that the existence of that sex may hereafter be demonstrated in the case of other species. The number of species hitherto recognized as natives of the British Islands is only twenty- nine. This number will doubtless be considerably increased when various areas, at present but little known, have been thoroughly examined. The only parts of the country which can be said to have received anything like a complete investigation are :—(1) the southern counties of Scotland, which have been most diligently overhauled by Dr. Thomas Scott of the “ Fishery Board for Scotland” and the late Dr. David Robertson of Cumbrae ; (2) the counties of Northumberland and Durham and—less completely— Cumberland and Westmorland, where the Rev. Dr. Norman and myself have worked for many years; (3) the Fen District of East Anglia including the Norfolk Broads and the Cambridgeshire Fens, which have been fairly well investigated by Dr. Robertson and myself, and more recently by Mr. Robert Gurney and others. But even in these well-worked districts, much, no doubt, remains to reward future investigators.* The species here recorded are. as follows :— Candonine. Candona candida O. F.

This is probably the commonest and most widely distributed form of the fresh-water Candone, but near the sea it seems generally to give place to C. angulata or C. neglecta, preferring the purer water of lakes, ponds, and streams. The drawings here given (figs. 1-11) are from specimens taken in a pool above high-water mark at Penmaenmawr, which, how- ever, would not be quite inaccessible to saline spray during storms. These agree closely with the descriptions and figures of Herr Kaufmann taken from Swiss specimens, and may I think fairly be taken to represent the typical form of C. candida. But the prehensile claws of the second pair of maxille as figured by G. W. Miller and Vavra differ so much from those of the form now under consideration, that I doubt whether they may not belong to some other species. The form referred to by Brady and Norman as var. twmida differs. scarcely at all from that here.taken as typical C. candida.

BRADY ON THE [ Feb. 1, of British Ostracoda’ as a variety of C. candida, the only examples then known to me being a few dried shells found at Gravesend and senf to me by my friend Professor T. Rupert Jones. I have since taken it abundantly in the river Coquet near the Hermitage at Warkworth, and in Hickling Broad, Norfolk, © in ditches neay Arundel and Felixstowe, and in a pool above high water at Penmaenmawr ; and I have specimens taken by the late Dr. D, Robertson in Lough Neagh. In all these places the water robably becomes slightly saline owing to the influence of sea- spray or perhaps occasional tidal overflow. The shell of this species is liable to be infested with circular papilliform excrescences which are probably the encysted stage of a trematode worm (Pl. XX. figs. 9, 10, Pl. XXX, figs, 1-4). A portion of the shell with the circular cysts is shown in fig. 10, and in the interior at two of the cysts may be seen the coiled young worm. And within the valves is occasionally to be found a fully developed worm, which has been examined for me at the Armstrong College, Neweastle-on-Tyne, by Miss M, V. Lebour, M.Sc., now of Leeds University. This is roughly represented in fig, 9. Miss Lebour pronounces jt to be one of the group Acanthocephala belonging to the genus Neorhynchus, prebably NV. claviceps Zaddach (see Pl. XXX. fig. 5). Her remarks on the specimens—which she kindly allows me to reproduce here—are as follows :— “Tt is about 1 mm. long with a thick skin and a retractile proboscis armed with few spines in number and arrangement the same as in JV. claviceps. The most anterior spines are large, brown- ish, and much wecurved, the two rows of smaller spines behind these are simpler and quite clear and colourless, In the thick sub- cuticular layer of the skin a few giant nuclei can be distinguished asin WV. claviceps. All the specimens seen appear to be males. There is only one testis instead of two as in WV, claviceps, which occurs near the centre of the body, and an indistinct vas deferens runs down from this, becomes more distinct where the glands appear, and opens at the extreme posterior end, The retractors af the proboscis are conspicnous, as are also the peculiar structures known as the lemnisci. Four specimens occurred in one Candona and single specimens in several others. Small Crustacea or water insects are the usual hosts for these Acanthocephala, and in the family Neorhynchide the larval forms are sexually mature, The adult AV. claviceps lives in the carp, Cyprinus carpis, and the larval form in the larva of Stalis lutaria, one of the Neuroptera (Cambridge Natural History, vol. ii. p. 185). It is interesting to get this speciés in a new host, for it does not appear to have been noticed in Candona before.” CANDONA NEGLECTA G, O. Sars, (Plate X XT, figs, 1-8.) 1887. Candona neglecta G, O.

XX. fig. 12). Abdomen terminating in two stout nipple-shaped projections of the genital lobe (fig. 13) which, however, are not so sharp nor so long as in C. siliquesa. Caudal rami bearing two not very long curved claws and near the middle of the posterior margin a single short hair. I have met with three or four examples of this species in examining afresh a gathering made at Belsay, Northumberland, so long ago as 1866. The small lake from which the specimens came has, however, been drained and, I believe, built over. Candona caudata has not as yet been noticed in any other British locality ; and Kaufmann is wrong in suggesting that the species referred to C. acuminata by Brady and Norman is identical with this species, which is, however, very nearly allied to Candona elongata. so nearly that I was disposed at one time to unite the two forms under one specific name. The characters upon which I rely to distinguish them are as follows :—the shell in C. caudata (as seen by transmitted light) is without any definite structural character, but bears a few distant circular papille, in C. elongata it is coarse and vaguely areolated: seen externally the shell of C. caudata has always a produced postero-ventral angle, which is not seen in (. elongata. The anterior antenne in C. caudata are not so stout nor are they so much dilated at the base as in the other species, and the joints of the last pair of feet are longer ; lastly the caudal rami are more slender and the marginal seta is situated near the middle of the ramus. It is possible that the specimen figured by Brady and Norman as perhaps the young male of C’, elongata may belong to C. caudata. CANDONA SILIQUOSA, nom, n.

The species referred by Brady and Norman to C. acuminata Fischer differs very considerably from the true acuminata, not only in the form of the shell but in certain points of internal anatomy. Iam indebted to Dr. G. W. Miller for specimens of that species which put the matter beyond doubt. Our British specimens are very similar in general aspect as well as in internal’ structure to C. cawdata Kaufmann, but they do not show the characteristic backward production of the shell, and the posterior 1910. ] BRITISH SPECIES OF OSTRACODA. 201 processes of the abdomen are sharper and more elongated, while there are also some slight differences im the setz oP the limbs. Another nearly allied species is C, proizi Kaufmann, but here the differences are more conspicuous. It therefore seems necessary to adopt a new name. It is probable that if male specimens were forthcoming, serviceable characters might be found, but none except females have hitherto been observed. In addition to the localities mentioned in the Monograph (loc. cit.) I have found C. siliqguosa in Barton Broad, Norfolk, and in ponds near Lyndhurst, Hants. Dr. T. Scott has taken it in many Scottish waters. CaNnDoNA ELONGATA Brady & Norman. (Plate XXII. figs. 1-8.) 1889. Candona elongata B. & N. (2) p. 100, pl. x. figs. 26-27. 1891. - fe (?) Vavra, (6) p. 111.

Shell, seen laterally, reniform, greatest height situated in the middle and equal’ to about half the length ; “oxiemiities rounded, the anterior narrower than the posterior ; dorsal margin evenly arched, ventral only slightly sinuated (fic. 1): seen dor sally the outline is rather narrowly ovate (fig. 2), pointed acutely in front, less acutely behind, width scarcely eaual to half the length ; left valve somewhat larger than the right and overlapping at the extremities. Surface of the shell smooth, colour brown. The anterior antenne are short and stout (fig. 3), the individual joints also short, all but the last two broader than long; the setze also short and stout, the three longest not as long as the antennule itself, the rest very much shorter; mandible-palp very short and stout (fig. 5); palp of the second maxilla more than usually dilated ; terminal joints of the second pair of feet short and stout (tig. 7). Caudal rami robust and curvate (fig. 8), the two apical claws nearly equal in length; the marginal seta moderately long and situated considerably beyond the middle of the limb. In the original description of C. elongata, it seems probable that two quite distinct species have been taken as representing the two sexes, but it is impossible at present, owing to want of specimens, to clear the matter up. Lough Neagh, where the species was taken years ago by the Rev. Canon Norman, is up to the present the only known British locality for it, though specimens referred to it have been found in Bohemia by Herr Vavra. Dr. Vavra, however, writes to me that his supposed specimens of C. elongata were identified by the late Herr Hartwig as belonging to C. protzi. The species is very closely similar to C. siliquosa; but he limbs genevally are much more robust and the individual joints thicker andl shorter; the caudal rami are stouter and more curvate, and the genital prolongation of the abdomen, which is so conspicuous in C. siliquosa, seems to be entirely absent. The shell is slightly larger than that of C. siliquosa. i) 02 DR. G. 8. BRADY ON THE [Feb. 1, CanpDonA PRotzt Hartwig. (Plate XXIII. figs. 1-8.) 1898. Candona protzi Hartwig, Zool.

Prehensile claws of the posterior maxille in the male very robust, strongly falcate, the tips obtuse, emarginate, and armed with a minute hyaline mucronate apical process (figs. 6, 7). Some of the specimens hitherto referred to Candonopsis hingslei belong undoubtedly, as has been pointed out by Dr. G. W. Muller, to C. protzi. This is certainly the case with many Scottish examples, as for instance those from Lochmaben and Lewis. It is by no means easy to distinguish, except by careful dissection, between such closely similar forms as C. protzi, C. kingsleii, C. hyalina, and perhaps sometimes C. fabeformis.

Female.—Shell seen laterally oblong, subovate, greatest height situated in the middle and equal to half the length ; extremities well rounded, the anterior the wider and more obtuse of the two (fig. 9): dorsal margin forming an even and somewhat flattened arch, ventral very slightly sinuated in the middle: seen from above (fig 10) the outline is much compressed, tapering gently to the anterior extremity, rounded behind, the right valve slightly smaller than the left, width equal to one third of the length ; hinge-margins depressed in the middle, forming a well-marked, shallow groove. Shell thin, structureless, showing no surface- markings whatever, mottled yeliow, the colour partly dependent on the contained animal. Length 0°88 mm. Posterior antennz devoid of any setose fascicle; the last two joints bearing a few stout, claw-like sete (fig. 11); no sensory sete. The mandible-palp is stout, the terminal joints short, bearing a small branchial plate at the base (fig 12); last pair of feet (fig. 13) bearing a very small forcipate process on the minute apical joint, also two sete of unequal length; the long penultimate joint has two marginal sete. Caudal rami (fig. 14) straight, slender, bearing two stout, perfectly smooth terminal claws, the dorsal one considerably in front of the other ; seta of the dorsal margin very short, distant from the apex about one third of the length of the limb.

Shell-surface smooth, very finely and closely punctated, colour white. Valves equal in size, bordered throughout, except on the hinge-line, with a wide, thick lip which is destitute of the pitted sculpture of the general shell-surface but is marked by numerous transverse hair-like lines (fig. 3): this appearance is, however, seen only in the separated valves and best when viewed by transmitted light. It forms a good diagnostic character. This species has not to my knowledge been noticed by any Continental author. It may possibly have been sometimes mistaken for the young of C. candida, from which, however, it may be at once separated by its evenly rounded extremities and flattened dorsal surface. Nor have I noticed in C. candida the delicate pitting of the shell surface which may always be found in C. lactea. ‘The soft parts do not disclose any noteworthy characters : the limbs—antenne especially—-are short and stout.

I took a single specimen of C. fragilis in a roadside pool near Carrick, Co. Donegal, and I am indebted to Dr. Thomas Scott for others taken by him in Scottish lochs—L. Arklet, L. Doon and Forfar loch; but in none of these cases have I found the contained animal in good condition and cannot therefore give complete illustrations of it; females only have been observed in this country. I did not observe in any of the imperfectly preserved British specimens, the conspicuous processes of the female genital plates, the figure of which (fig. 10) was drawn from a specimen kindly sent to me by Dr, Vavra. In two of Dr. Scott’s specimens I found parasitic organisms which appear to be the scolices of some kind of Zenia: one of these is shown in Pl. XXII. figs. 18, 14. The two specimens in which the scolices were found are from different lakes—Loch Arklet and one or other of the two further lakes referred to above, so that it may be fairly inferred that this particular species acts as intermediate host for the Zenia. In the ‘Cambridge Natural History,’ vol. i1. p. 84, several Ostracoda and Copepoda are men- tioned as the intermediate hosts of Cestode Worms which attain their final development in the intestines of Birds (Anatide), the larval forms belonging to the genus Cercocystis. And Professor R. Blanchard has described in the ‘Mémoires de la Société Zoologique de France’ (1891) a new genus of these worms found in the same group of birds, the scolex of which occurred in an Ostracod (“‘Cypris cinerea” Brady). This species Professor Blanchard calls Hchinocotyle rosseteri, and it may possibly be identical with that here referred to*. In F. rosseteri, however, the crown of hooks is stated to be composed of tem spines, whereas in the scolices found in Candona fragilis there are, so far as I can make out, éwelve.

Hartwig, in 1899, proposed to constitute a subgenus* of which C. euplectella would be the only known member, the characters of which depended chiefly on the number of joints of the posterior antenne. But these and other minor characters seem to me too trivial to warrant the separation of a new sub- genus. Genus Canponorsis, Viavra. This genus was by Vavra separated from Candona on the strength of the following characters. The second pair of antennz are, in the male, six-jointed, and have two “sense organs” on the fourth and fifth joints; the mandibular palp is exceedingly long and slender; the second pair of maxille have a branchial append- age of three plumose filaments ; the caudal rami are slender and have no sete on the posterior margin. These characters were founded on the male only, the female being unknown to Herr Vavra, but they apply likewise to the female. The only hitherto recognized species of the genus is O. kingsleii Brady & Robertson. * “ Candona euplectella (Robertson), bildet eine selbsti andige Gattung,” Zoologisch Anzeiger, Bd. xxii. no. 592, 1899. 1910.] BRITISH SPECIES OF OSTRACODA. 209 CANDONOPSIS KINGSLEL Brady & Robertson. 1870.

Anterior antennz six-jointed, slender, their terminal setz long and slender; posterior antennz four-jointed, moderately stout (tig. 3); mandibles (fig. 4) bearing a stout four-jointed palp the first jot of which is provided with a 4-setose branchial plate ; first and second pairs of maxille of the usual form (figs. 5, 6); feet of the first pair (fig. 7) four-jointed, inner margin of the second joint rather densely setose, last joint bearing two very unequally sized claws and a short seta: the homologue of the last limb is a short, slightly curved, club-shaped process with a small proboscidiform apex (fig. 8). Caudal rami simple, straight, with smooth, non-setose margins, bearing two terminal claws, the uppermost quite twice as long as the lower ; marginal seta very small and situated almost close to the apical claw (fig. 9). Male unknown. This species, which, though collected in 1897, has remained unrecognized until now, is, I have little doubt, identical with that described long ago by Dr. Baird under the name of Candona similis, his description and figures agreeing in every particular with my specimens. These, of which I took only a very small number—some three or four—are from “the Mere” at Scar- borough, a small sheet of fresh water lying under Oliver’s Mount, and I have more recently received specimens from Mr. Robert Gurney, taken in Catfield Fen, Norfolk. The characters which essentially distinguish this genus from * oupdos, a cripple. 1910.] BRITISH SPECIES OF OSTRACODA. 211 other Candonine, are the atrophied posterior foot, and the abnormal structure of the caudal rami, the terminal claws of which differ in their comparative size from those of other species, the uppermost of the two being much the larger, and the marginal seta is closely approximated to the claws. In addition to the type species, I have recently detected in a Scotch mounting kindly sent to me by my friend the Rev. Canon Norman, a few specimens of another form distinct from S. similis, but undoubtedly belonging to the same genus: this I propose to name S. normant. SIPHLOCANDONA NORMANI, sp. n. (Plate XX VII. figs. 10-14.) Shell, seen laterally, compressed, oblong, siliquose (fig. 9), greatest height situated in the middle, not nearly equal to half the length ; extremities narrowly rounded, the posterior somewhat oblique ; dorsal margin gently and evenly arched, ventral slightly prominent in front, gently sinuated behind: seen from above (fig. 10), com- pressed, subovate, greatest width equal to the height and situated in the middle, gradually tapered to the extremities, which are acuminate : surface of the shell smooth, colour milk-white. Length 0°83 mm. Claws of the caudal rami stout (fig. 14), the uppermost more than twice as long as the lewer; the marginal seta short, stout, and claw-like, closely approximated to the terminal claws. The only specimens of this curious species which I have seen were included in a series of Candonopsis kingsleii, from which, indeed, it was not very easy to distinguish them. They were taken by the Rev. Canon Norman in pools near the margin of Loch Fadd, Isle of Bute. Subfam. HEePETOCYPRIDIN®. Genus Herrerocypris Brady & Norman. HERPETOCYPRIS REPTANS Baird. 1850.

Length 2°55 mm. (,/5 in.). The antennal sete are beautifully plumose and reach to the extremities of the terminal claws (fig. 3); the lobe of the first maxilla next following the palp has two of its claws laterally denticulated and terminating in a spear-head (fig. 5); palp of the second maxilla (fig. 4) narrow and elongated, masticating portion twisted upon itself toward the base; posterior legs of the usual form (fig. 6), the last joint small, divided into three distorted finger-like lobes, bearing a single long seta and a strongly falcate claw. Caudal rami (fig. 7) slender, bearing two unequal, strong, apical claws which are marginally pectinated, and two sete, a small one on the dorsal and a uch longer one on the lower angle; the dorsal margin of the ramus is ornamented at its distal end with about four series of delicate spines separated from each other by slight depressions of the margin; these spinules, reduced very much in size, are continued without intermission along the proximal portion of the limb. This is so closely allied in genera] form and characters to the foregoing species, H. reptans, that it seems to me undesirable to assign it to a distinct genus (Stenocypris) as has heen proposed by Professor G. O. Sars, especially as the variations in anatomical points are comparatively unimportant. A single specimen was taken many years ago at Lyndhurst, and remained in my collection unnamed and without description. Since that time I have found it in considerable abundance in the Hatchett Pond (New Forest), in ditches near the River Arun (Sussex), in Conway Marsh (North Wales), and in a pond near Sellafield (Cumberland).

A very distinct and well-marked species, far different in shell- characters from any other fresh-water form. There are also several minor abnormalities in the structure of the contained animal which seem to warrant the use of the generic name proposed in 1896 by Brady and Norman (Joc. cit.). The more important distinctive characters are: (1) the extremely short antennal setz; (2) the smoothly edged claws of the outer lobe of the first maxille, and the dilated extremity of the palp; (3) the perfectly smooth margins of the very slender caudal rami, and the position of the dorsal seta very near to the apical claws; (4) the simple termination of the second pair of feet which bear on the small terminal joint only two setz, one long, and one short and claw-like. The species is nowhere common, but is widely distributed in England. It does not seem to have been found in Scotland or Treland, but is noticed by several Continental authors. In addition to localities already published I have taken it in a backwater of the River Wye at Rowsley, Derbyshire, and Mr. Scourfield records it from reservoirs at Walthamstow and Purfleet, Essex. The generic characters mentioned above, though none of them separately very important, may, together with the exceptionally marked characters of the shell, be taken as suflicient to warrant the separation of the species as the type of a distinct genus, 214 DR.

Shell, seen laterally, subreniform, highest in the middle, height greater than half the length; extremities rounded, the posterior much the broader of the two; dorsal margin arched, sloping more abruptly behind than in front: seen from above the outline is ovate, excessively tumid, width equal to two-thirds of the length ; anterior extremity abruptly tapered and forming a mucronate prominence, posterior broadly rounded ; the two valves are nearly equal in size but have the two extremities and, in a smaller degree, the ventral margin incurved so as to form a very conspicuous flange or duplicature (fig. 1). Shell-surface quite smooth, colour white. Length 1:05 mm. Setze of the posterior antennz very short, arranged in a distinct fascicle of four (fig. 2); caudal rami (fig. 3) slender, the two terminal claws equal in length, and almost imperceptibly pectin- ated, marginal seta very small and not far removed from the claws. A very well marked species, recognizable at a glance by its excessive tumidity and produced anterior extremity. The internal duplicature of the margins of the valves is more pronounced than in any other species known to me. I have taken it in the Warn Burn, Northumberland, near Sunderland, and in the River Lathkill, Derbyshire; it has been found also by the late Dr. Robertson and by Dr. Thos. Scott in several Scottish localities. ‘ Genus [tvopromus G. O. Sars. Shell highly compressed, and, seen laterally, oblong; dorsal edge straight in the middle, ventral sinuated. Valves generally not very unequal, the left the larger; surface usually longitudinally striated. Sete of the inferior antennz poorly developed, not reaching beyond the terminal claws. Caudal rami coarse, armed with three strong claws increasing in length distally. Animal devoid of swimming power. Propagation parthenogenetical. This generic definition is slightly condensed from that given by G. O. Sars in a paper on the “ Freshwater Entomostraca of New Zealand,” 1894. As applying to the British species, the state- ments as to the straight dorsal edge and longitudinal striation 1910.] BRITISH SPECIES OF OSTRACODA. 215 of the valves must be eliminated, but in other respects the generic definition is perfectly applicable. Whether the fact of the three-clawed caudal ramus is sufficiently important to call for separation from Herpetocypris may perhaps be doubted, but it seems to be the only distinctive character, if we except the not very important matter of shell-sculpture ; from Candona, on the other hand, it is differentiated by the anatomical structures con- nected with “‘ parthenogenetic” propagation, as well as by the presence, apparently, in the type species, of a setose fascicle on the posterior antenne. The two British species at present known are Llyodromus olivaceus and I. robertson. InyoprRomus RopEeRTsonI Brady & Norman. (Plate XXVIII. figs. 10-15; Plate XXIX. fig. 12.) 1889.

In particular, I believe that I am able to compare more satisfactorily than has yet been done the intestinal tract of this animal with that of its allies. When the animal is cut open the stomach is seen to occupy the greater part of the abdominal cavity; it completely hides the liver, which is behind it. A transversely running section of the colon is nearly all that is visible of that gut, and it lies between sections of the small intestine. The only part of the gut upon which I made observations worth recording as a contribu- tion to our knowledge of the anatomy of this animal, was the colon. Of this section of the gut Gratiolet * wrote: ‘“ Le célon ascendant décrit une ligne sineueuse dans laquelle en peut compter six anses successives. 1] y a ensuite un célon transverse, une 5 iliaque médiocrement courbée, placée trés-prés de la ligne médiane, et enfin un rectum trés-musculeux.” This description is not in the present state of our knowledge of the mammalian gut enough to indicate the relationships with other Artiodactyles. Dr. Crisp figures the entire alimentary canal of this Pachyderm, but gives so generalised a figure that no details can be ascertained beyond the well-known absence of cecum, and the proportions, roughly speaking, between the long small and the short large intestine. : The figure of Gratiolet is better, and represents some of the essential features of this gut in the Hippopotamus as I would interpret them. ‘The six successive loops of the colon are given in his illustration, and then the sharp bend backwards to form the straight running descending colon and rectum. According to Flower, ‘‘ The colon is comparatively short, about one-tenth of the whole intestine, and instead of the spiral convolution found in most Artiodactyles, its first or ascending part is thrown into about six transverse folds, and then it pursues the usual course of the transverse and descending colon.” This description agrees entirely with the figure of Gratiolet. There are, as I believe, no further notes upon the alimentary canal of the Hippopotamus tending to explain its relations to and differences from the alimentary canal of other Artiodactyles, save a brief reference by Dr. Mitchell in his comparative survey of the Mammalian gut 7. The colon of the example of /:ppopotamus which I have myself examined appeared to be like that of other examples; but my own observations enable me to add some details which serve to fix more plainly, as I think, the correspondence between the colon of this animal and that of others among its allies. It is to be noted, in the first place, that the colon has, to begin with, a * Loe. cit. p. 395. + Trans. Zool. Soc. vol. xvii. 222 MR. F. E. BEDDARD ON THE [ Feb. 1, descending direction. Its origin from the small intestine— though, as is well known, there is no cecum—is quite marked, and cannot be missed. ‘This descending origin is decidedly on the left side of the body, the origin of the duodenum on the right side really occupying the position so often seen in mammals to be occupied by the cecum. ‘The first part of the colon is quite loosely arranged, and although six tolerably regular folds are figured by Gratiolet, it must not be inferred from the stress laid upon these folds by him and by Flower, that they are definite entities. On the contrary, the colon is in this region entirely lax and can be passed through the fingers in a perfectly straight line without in the least damaging the mesocolon by which it is suspended. ‘There is, in fact, no really definite series of colic loops. ‘The colon happens to lie in this way or that to meet the conditions of space; but it is as free from any anse coli as is that of the Primates or the Marsupialia, &c. We have to note therefore, in the first place, that Hippo- potamus in the arrangement of the gut is more primitive than is any other Artiodactyle, or indeed than any other Ungulate, excepting perhaps the Elephant. In surveying the various Orders of Mammals with reference to the coiling of the gut *, I was unable to find any Artiodactyle which had not a very specialised gut. Even Tragulus, which lies near to the base of the series, so far as living Artiodactyles are concerned, showed all the typical artiodactyle features in the arrangement of its colon and in the permanent loops thereof. The animal therefore furnishes additional. evidence in favour of the contention that the gut undergoes an evolution in separate groups, the stages being in all cases the same in general outline. A knowledge of the intestinal tract of the Hippopotamus thus fills a very considerable hiatus in what is known concerning the group of Artiodactyles. It is, however, important to notice that while the gut of the Hippopotamus represents Stage II. among the Artiodactylest, a stage which has been hitherto missing in that group, there is not a precise correspondence between the gut and that of, for example, a Kangaroo which represents the same stage. The intestinal tract of Hippopotamus is distinctively Artiodactyle, or at least Ungulate, in various features to which I now shall direct attention. In the first place, the position of the vanished cecum is on the left side of the body, and the colon therefore commences by passing ina downward direction. This is precisely what we find in other Ungulates, for example in Hyraxt. The second feature of importance in which the gut showsan Ungulate, and this time a distinctively Artiodactyle, character, is in the * “On the Anatomy of Antechinomys, &c.,” P. Z. S. 1908, p. 561. + Tam not absolutely certain whether the gut of Hippopotamus may not really belong to Stage I. Gratiolet speaks of a continuous mesentery for both small and large intestine. Unfortunately my own notes are defective as to this point. + See Beddard, “On the Anatomy of Antechinomys, &c.,” P.

But it occurs in other Artiodactyles also. The enormous stomach of the Hippopotamus has been described by so many writers, indeed by all those quoted above as well as by some earlier contributors to our knowledge of this ‘ Pachy- derm,” such as Daubenton, The various chambers of the stomach seem to be now well understood, and in consequence I have not troubled myself to revise the existing knowledge upon this subject. But one matter which I noted in connection with that organ has not been dwelt upon by previous writers. If it has been noted at all, it has escaped my attention. I found in the case of the young animal which I examined, that along a line parallel with the elongated spleen and about coextensive with that organ, the stomach was attached to the ventral parietes by a strong white band of connective tissue. The direction of this was rather obliquely longitudinal, being somewhat between the transverse and the longitudinal planes of the body. On the opposite side of the body the stomach was attached to the dorsal parietes by an equally strong ligament. This latter may, of course, be regarded as the mesogaster. But the homologies of the ventral ligament are not so clear. I showed the structure to my colleague Dr. Plimmer, who was of opinion that the ligamentous band was not a pathological structure, and indeed it hardly gave the impression of being of that nature. It may perhaps be regarded as representing a portion of the ventral mesentery, of which in other mammals the falciform ligament is the only representative. In the case of the Hippopotamus, however, the direction of this ligament was not quite such as to lead to a confident assertion of this view of its homology. The attachment of the stomach to the ventral parietes is, I believe, a new structural feature for a mammal. It obviously reveals the conditions which obtain in the Crocodilia (and in Birds). The fixation of so huge an organ as is the stomach of this great beast when distended with food would seem to be a most useful fact in its economy, and it is possibly to be looked upon in this light. For one can hardly make the com- parison suggested with the aquatic Crocodilia save as due to a like need. The heart in the example which I have studied does not show any marked bifidity of its apex such as has been described in this animal. Indeed nothing of the kind was obvious to me. As Gratiolet has observed, there are no corpora Arantii in the valves of the pulmonary artery. These nodules are also absent from the same valves in the Peccary. The accompanying drawing (vext-fig. 22, p. 224) illustrates the interior of the aorta and pulmonary artery, and shows the erescentic depression in each which represents the former orifice of the ductus Botalli. It will be noted that, in accordance with the direction of the tube (which is a solid band in the adult and indicated in the figures already 224 MR. F. E, BEDDARD ON THE [ Feb. 1, referred to), the rudimentary orifice is thickened along one side ; b is the aortic orifice, a that in the pulmonary artery. Text-fig. 22. The aorta and pulmonary artery of Hippopotamus opened up to show the vestigial orifices (a & 6) of the ductus Botalli. The right ventricle fully opened is shown in text-fig. 23. It will be observed from the very accurate figure that the free wall of that ventricle is not sculptured into columne carnose, but merely presents an honeycombed appearance. It is in fact only unevenly pitted with variously sized excavations which acquire, near to the attached wall of the ventricle, some approach to the more usual arrangement of trabecule. The auriculo-ventricular valve itself was markedly tricuspid, and it 1s shown in the text- figure not in its normal position. For the cutting and reflection of the free wall of the ventricle has carried with it the muscles attached to the middle flap of the valve, the infundibular cusp of human anatomy. On the extreme left the valve is attached to the septal wall of the ventricle in a way which is not universal among Mammals. There is, in fact, a thick and well-marked papillary muscle in this situation which is shown in the figure, as are the other papillary muscles, as striated longitudinally, to distinguish them more definitely from the walls of the ventricle. This septal papillary muscle is quite short and very stout. The anterior papillary muscle is rather complex. Its actual origin from the ventricular wall is marked by the letter ‘“ A ” towards the right of the drawing (text-fig. 23), and a portion of it also arises from the neighbouring cut edge marked “ B.” The actual course of the papillary muscle and its subdivisions is € 19102].

It will be noticed that this, the anterior or great papillary muscle, arises very near to the junction between the free and the septal wall of the ventricle.

The arrangement of these is such as to suggest a former great extension of the membranous valve towards the apex of the ventricles. It seems to me from the account given by Gratiolet * of this valve, that in the specimen which he dissected the papillary muscles of the septal half of the valve were not much developed. Otherwise there is no great difference between his account and that given above, save that I have entered into the matter some- what more in detail. Dr. Crisp, in his account of the Hippopotamus, remarks of the right auriculo-ventricular valve that the ‘‘ tendons of the Tricuspid valve, seventeen in number, spring from three columns (so-called), one prominent and nipple-like, the others but little raised above the surface.” I fancy from this account that the specimen examined by that anatomist was not unlike the one described by myself in the present communication. My figure shows a number of chorde tendinee which is not very far from the number asserted by Dr. Crisp, while his description of the musculi papil- lares, although not absolutely agreeing with the arrangement of those muscles as I saw it, emphasizes, as I think, the stout elevated muscle to the extreme right of the ventricular cavity in the figure. The accompanying figure (text-fig. 24) represents the interior of the right auricle of the Hippopotamus, which has never been figured so far as I am aware, though many of the features there visible are referred to by previous writers.

Additions to our Knowledge of the Fossorial Wasps of Australia. By Rowxianp E. Turner, F.Z.S., F.H.S. [Received February 16, 1999. | (Plates XX XI. & XXXIT.*) The material for the following descriptions is nearly all in the British Museum collection, most of the Thynnide having been received from Mr. H. M. Giles, and the Ceropalide from the collection of the late Gilbert Turner. We may now assume that our material, though very incomplete, is fairly representative of the Fossorial Hymenoptera of Australia. It is most striking that of the species described up to the present time nearly one- half belong to the family Thynnide, which is almost entirely without representatives in any other part of the world excepting South America. The wingless condition of the females must operate against a wide distribution, but I think it quite possible that the family as it exists to-day is derived from less specialised and much more widely distributed ancestors of a form more nearly resembling the modern Scoliide. The mouth-parts of the females in most Australian species are aimost rudimentary, while in South- American species they are usuaily developed, so that the degree of specialisation in the two countries differs considerably. I am inclined to believe that the ancestors of the group have been exterminated in the northern continents and Africa by the keener competition existing on large continental areas, and that their descendants have survived on the smaller and more isolated land- areas of the south. In South America the species are very few in the tropical lowlands, but increase in number in the temperate and mountainous regions. In Australia they are most numerous in the south-west and decrease in number as they come into contact with a fauna of a more Oriental character in Queensland. Ido not therefore look on the occurrence of the group in such distant localities as any proof of a land connection in the past, but rather regard the South American and Australian species as isolated survivors. The Mautillide of Australia mostly seem generically distinct from those of other countries, and the Scoliid genus Anthobosca is elsewhere only represented by a few species in South America, South Africa, and Madagascar, but has been found fossil in Colorado. The Ceropalide do not show any remarkable peculiarities, being nearly all representatives of wide- ranging genera. It is unfortunate that the old name for this family, Pompilide, has to be superseded. * For explanation of the Plates see p. 356. 254 MR. R. E. TURNER ON THE | Feb. 15, Fam. MUTILLID-.

Fam. THYNNID 4A. The material in this family dealt with here is mainly derived from the splendid collection sent by Mr. H. M. Giles from South- Western Australia to the British Museum. Some other species described are from the collection of the Berlin Museum and from collections sent to me by Messrs. G. A. Waterhouse and R. Illidge. Mr. Giles has also furnished valuable information as to the habits of the species. He says that, in spite of the minute mouth-parts, the females do take food, though exclusively liquid. This, he has observed in many species, is disgorged by the males and placed in the mouth of the female, which is carried by the male for some hours. The larger females also help themselves. In a female examined for me by Mr. W. Wesché there was no trace of pollen, though the specimen had been taken on Leptospermum-blossom by Mr. Illidge ; whereas in the South-American female Spilothynnus bituberculatus Turn. a good deal of pollen was to be found, showing that the more normal mouth of the South-American females is associated with a difference in feeding-habits. In several cases Mr. Giles captured specimens cross-paired, males of the same species being taken carrying widely different females. There can here be no question as to any mistake in the observation, Mr. Giles being a most careful observer. Professor Dahl observed in New Britain that the female of Thynnus serriger Sharp is to be found on leaves with the mandibles wide open, probably for the purpose of seizing the male. I am inclined to think that the male may be used in this way as a means of transport, and that the strongly developed claspers may be used in carrying the female without coupling actually taking place in cases where the two are of different species. On the other hand, occasional cross-pairing among the more nearly allied species is not. wholly improbable. Mr. Giles has also observed a male of one species going into a Bembex-burrow and returning coupled withafemale. On digging up more Bembex-burrows he succeeded in finding another female of the same species, thus showing that my suggestion that some of the smaller species are parasitic on Bembex is almost certainly correct.

The females sent are similar to that previously described by me froma damaged specimen as the female of 7. tuberculifrons Sm., but the low carina on the pronotum is absent. I am therefore driven to the conclusion that the speci- mens with the red abdomen (basalis) and those with the black abdomen (tuberculifrons) are two forms of the same species distinct from vastator Sm., though intermediate colour-varieties do not seem to occur. One specimen, apparently identical with basalis, is, however, paired with a female closely resembling that described by Smith as vastator, though differing in the presence of four raised carinee instead of three at the base of the second dorsal segment.

Very similar to trilobatus in general appearance, but the hypo- pygium of the male and pygidium of the female are very different. J am not sure which name has priority for this species. Schulz’s description was published apparently late in June, though no date is given ; whereas my diagnosis in the key to the species appeared early in June, though the full description did not appear until August. I feel little doubt that the descriptions refer to the same species, though Schulz does not give any notice of an apical spine on the hypopygium either in the text or the figure; but this spine is very liable to be broken in many species. The species is in no way connected with Hnteles, in which the males always have the apical spine strongly recurved as in /ehagigaster. ZASPILOTHYNNUS LIGNATUS, Sp. D. 3.

In working on this family I have attempted to use the classifica - tions of Kohl and Ashmead. The former is, however, hardly to be taken as more than a sketch, and is not worked out with much detail, though useful as far as it goes. Ashmead on the contrary makes many new genera, some of which will doubtless stand, but the characteristics given are often insufficient ; and too much importance is attached to minute points of neuration, which an examination of a large collection shows to be often more Poon FOSSORIAL WASPS OF AUSTRALIA, 309 or less variable in geographical races. But the habit of this author of taking undescribed species as the types of his genera is most objectionable, and no editor should have published work in which such a fault is evident. The form of his tables is also occasionally incorrect or unfinished, making them very difficult to follow. AGENTA BARBATULA, Sp. n. @.

The Indian species identified as callisto by Colonel Bingham is intermediate in the form of the petiole, but differs both from callisto and dispersa in the form of the median segment which is slender and much longer than broad. PP. erigone Bingh. is really nearer to the present species than his callisto. The difference in the point of origin of the cubitus of the hind wing is interesting as showing the slight systematic importance that can be attached to a character largely used by both Kohl and Ashmead in their classi- fications of the family.

He states, however, that there is no transverse groove on the second ventral segment, whereas in lunwlatus it is distinctly visible, though in some specimens almost hidden by the apex of the first segment. The hind tibie, though feebly spined, are much more distinctly so than is usual in Psewdagenia, so that it can only be placed in the genus with doubt. CRYPTOCHEILUS AUREOSERICEUS Guer. st.

Calopompilus Ashm. is in my opinion a good genus, unless indeed it has to sink under Hemipogonius Sauss. The present species is not a typical example of the genus, as the cubitus of the hind wing originates a little before the transverse median nervure and the submedian cell of the fore wing is very little longer than the median. The male has no transverse groove on the second ventral segment, but this character seems to be common to the males of this genus. The differences noticed in neuration do not seem to be constant, for in some specimens, including the type, the cubitus of the hind wing is very nearly interstitial with the transverse median nervure. 1910. | FOSSORIAL WASPS OF AUSTRALIA. 323 CALOPOMPILUS VELOX Sm.

The extreme specimens of a series show considerable difference in the sculpture on the mesopleure, but intermediate forms, of which the type of globosus is one, seem to occur. The pile on the sides of the abdominal segments seems to be present in all fresh specimens, and the brown margin of the abdominal segments is variable, almost absent in the type. I have not seen any specimens exceeding 17 mm. in length. Spuex (Isopont1A) aspirus Kohl, st. NUGENTI, st. n. @. Differs from the typical form in the following details :— the second joint of the flagellum is distinctly longer than the third, the punctures on the thorax are very shallow, the pubes- cence on the thorax and median segment is black, erect, and sparse, and the apical joint of the tarsi is ferruginous, leaving only the coxe and trochanters black on the legs. Length 19 mm. Hab. Cairns, Q. Kohl gives the locality Sikkim, but expresses doubt as to the correctness of the information. In my opinion abditus is scarcely distinct from aurifrons Sm. from Aru, the latter species differing in the testaceous margins of the abdominal segments which are also slightly pruinose. In Queensland the present form seems to be very scarce and has not been previously recorded. SPHEX VESTITUS Sm. Sphex vestita Sm. Cat. Hym. B. M. iv. p. 248 (1856), @. Sphec pretexta Sm.

This fine species is nearly related to monetarius Sm., from which it differs in the narrower pygidial area, the greater length of the third cubital cell on the cubital nervure, and the paler colour of the wings and of the pile on the abdomen. The sulcus on the scutellum is absent in the type of monetariws, which is from North India. The species has a wide range in Africa, but in specimens I have seen from West Africa the eyes approach each other more closely on the vertex than in the typical form, and the pygidial area is narrower as in the Australian species.

The seventh, eighth, ninth, and tenth joints of the flagellum are slightly produced at the base beneath, the eleventh is broadened and flattened above and produced into a tubercle beneath, the apical joint is sharply curved and terminates in an acute spine. The three basal joints of the anterior tarsi are broadened, but not strongly so. The tubercle of the second ventral segment is truncate at the apex, resembling that of B. tuberculiventris Turn. in form, and the sixth ventral segment is armed with a triangular plate. Intermediate femora not serrate. The clypeus is white and is very prominent at the base, then almost vertically truncate to the apex, the extreme base is black. Hab. Mackay, Q. (Turner). $ 2.

Very near airifrons Sm., but differs in the more even serration of the intermediate femora, which in this species is continued from the apex almost to the base, whereas in atrifrons the apical half is not serrate and the extreme base is rather abruptly broadened and also smooth. In atrifrons the lobes of the basal joint of the anterior tarsi are more strongly developed and the seventh dorsal segment is more narrowly rounded at the apex. BEMBEX AUREOFASCIATA, Sp. nh. (Plate XXXIT. fig. 14, 3.) 6. Mandibles with one tooth on the inner margin; labrum longer than mandibles, smooth, and without a suleus. Clypeus convex, somewhat flattened in the middle, covered with very short, delicate, white pubescence. Inner margins of the eyes parallel; the antenne inserted a little further from each other than from the eyes, the scape rather stout; second joint of the flagellum nearly as long as the third and fourth combined, none of the joints emarginate, spined, or hollowed. Anterior tarsi not thickened ; the basal joint with six spines on the outer margin including the two apical spines, the outer margin very feebly lobed and narrowly margined with black; intermediate femora serrate beneath ; intermediate tibiz with the apical spines well developed. First ventral segment with a longitudinal carina at the base; the second segment with a very strong longitudinal carina, which is rounded, curved, and very prominent at the apex, very similar in shape to that of B. museca Handl. Sixth ventral segment not modified, the eighth ending in an acute apical spine. Seventh dorsal segment rounded at the apex. Closely and finely punctured; the head, thorax, and base of the abdomen with cinereous pubescence. Black; the mandibles (except at the apex), labrum, clypeus, the extreme base of the scape, pronotum, tegule, the scutellum (except in the middle), postscutellum, femora, tibiee and tarsi, a broad band at the base of the first dorsal segment of the abdomen, a narrow band at the apex of the first ventral segment, a broad band on the middle of the second segment above and beneath marked with a small black spot on each side on the dorsal surface, and a narrower band emarginate on each side anteriorly on the third dorsal segment, orange-yellow.

Allied to B. atrifrons Sm., but in that species the seventh and eighth joints of the flagellum are not normal and there is a seventh spine on the basal joint of the anterior tarsi; the colour is very different, being in awreofasciata of the orange shade which is characteristic of many Australian Aculeates, but which does not occur, so far as I know, in any other species of Bembex. 1910. ] FOSSORIAL WASPS OF AUSTRALIA. 355 Genus AucHENOPHORUS Turn. Auchenophorus Turn. Ann. & Mag. Nat. Hist. (7) xix. p. 270 (1907). I was quite wrong in considering this genus as in any way related to the Ampulex section of the family. The true affinity is with Vitela, with which the neuration agrees fairly well, but the radial cell is not appendiculate and the cubitus of the hind wing originates further from the transverse median nervure; in these points agreeing with WVitelopterus Ashm. In that genus, however, the mandibles are deeply emarginate on the outer margin. The species of Auchenophorus resemble Mutillide, with which the female of A. fulvicornis was taken at Cairns, running on the ground with closed wings in localities where females of Ephutomorpha were plentiful.

Clypeus rather strongly advanced in the middle anteriorly, the anterior margin undulating at the sides, the produced apical portion smooth, the remainder closely and finely punctured. Head opaque, very minutely punctured, with a short longitudinal carina on the front; the eyes half as far again from each other on the clypeus as on the vertex; antenne inserted nearer to each other than to the eyes; the second joint of the flagellum scarcely longer than the third. Pronotum rounded at the anterior angles. Thorax very finely and closely punctured. Median segment very finely and closely obliquely striated, punctured between the strie, a longitudinal sulcus from the base to the apex in which lies a low carina. Abdomen opaque, very minutely punctured, the segments depressed on the apical margin and bordered with fine silver pubescence. Second cubital cell half as high as the third, receiving the two recurrent nervures near the base and very close to the apex. Black; the tegule testaceous at the apex.

Easily distinguished from the allied species by the shape of the clypeus, which is broadly rounded in fuscipenne Sm., and much less produced in spinole Shuck. The type is a male in which the second joint of the flagellum is much longer than the third. The clypeus of the male is produced into a point; but I think I am right in placing the female described above with perplexum. Pison ARGENTATUM Shuck. Pison argentatum Shuck. Trans. Ent. Soc.

Upper side: both wings dark orange-red with black apices and margins. Fore wing with a large pure white subapical patch. Under side pale brownish yellow, with the usual black markings and white spots, and in addition to these on the hind wing, arising from the base and from the anal margin near the base, are two prominent black bars running almost at right angles to the black costal bars.

The markings on the under side of the hind wing give this ‘insect a very different appearance from any other described in the genus. PENTILA PARDALENA, sp.n. (Plate XX XIII. fig. 1, 3.) Male. Upper side: both wings pale yellow, darker towards the base, heavily spotted with black over the cellular and discal areas ; apex and outer margins broadly black, containing rows of pale yellow spots. Under side clear pale yellow, darker on the hind wing and towards base of fore wing. JDiscal and cellular black spots as above, except on the hind wing where there are several additional black basal spots. The apex and outer margin have a marginal and a submarginal row of large elongated black spots running alternately. Expanse 1,%5 inch. Hab. Bitje, Ja river, Cameroons, 2000 ft., dry season (@. L. Bates). Type, Mus. Druce. This is a more heavily spotted form than Pentila christina Suffert* (a photograph of the type of which I have before me) and the ground-colour below is clear, not speckled as in that insect. PENTILA INCONSPICUA, sp.n. (Plate X XXIII. fig. 3, 9.) Female. Upper side: allied to Pentila petrea Hew., paler and without the reddish tinge. In the fore wing the dark apical border is much broader, and there is an additional black spot on the disc situated near the base of cell 2. On the hind wing there is trace of a submarginal row of small black spots situated between the veins, which in some specimens is clearly indicated. Under side: differs from that of P. petrea by the addition of the black spot in cell 2, by the absence of the two black spots at the angle in the fore wing, and by the submarginal row of spots on the hind wing being placed further in from the margin. Expanse 1,3, inch. Hab. Upper Kasai district, Congo Free State, Uganda. Type, Mus. Druce. This insect is even paler than P. preussi Staud., a large series of which we have received from the same locality. The British Museum collection contains six specimens from Entebbe, Uganda. PENTILA PARADOXA, sp.n. (Plate XX XIII. fig. 4, 3.) Male. Upper and under sides: both wings semitransparent, creamy white, without markings.

PENTILA BITJE, sp.n. (Plate XXXITI. fig. 5, ¢.) Male. Upper side: both wings uniform pale cream; semi- transparent. Fore wing with the apex narrowly fuscous, and the costal margin dusted with fuscous scales; three clearly defined circular black spots on the disc, placed as follows: one in the centre of the cell; oneat the end of the cell, and one in cell 2 rather before its middle. Hind wing also with three black spots, placed, one on the costal margin before the middle, above the cell, one at the end of the cell, and one in cell 2 near its base. Cilia concolorous with wings. Under side as above excepting that the fore wing is without the dark apex and that the whole area of both wings is slightly dusted with fuscous scales. Abdomen fuscous above, pale below. Palpi and legs ochreous. Female. Marked exactly as the male. Expanse 14 inch. Hab. Bitje, Ja river, Cameroons, 2000 ft., dry and wet seasons (G. L. Bates). Types, Mus. Druce. Described from seven specimens. “The black spot in cell 2 of the hind wing is very minute in several examples, and in two is entirely wanting, but on one wing only. There is also a specimen in the British Museum from the Cameroons. MIMACRHA LANDBECKI, sp. n. (Plate XXXIV. figs. 7 g, 8 2.) Male. Upper side: fore wing dull blackish brown, with the inner marginal area brownish ochreous, shading paler and decreasing in width to vein 4. A pale yellow, slightly ochreous edged, subapical band placed rather more than half-way between the end of the cell and the apex and crossed by the brown nervules. Hind wing brownish ochreous, gradually merging into a brownish black apical and outer marginal area ; inner margin, excepting extreme edge which is pale yellow, fuscous. Under side: fore wing—costal area to subapical band black, * Pentila tirza Hew., Ent. Mo.

Hind wing: ground-colour blackish brown, thickly dusted with reddish ochreous scales over the cellular and basal areas, and arising from the cell are a number of narrow ochreous lines composed of dusted scales, which before they reach the margin become divided into two, The basal area supports ten deep black spots, most of which are distinctly ringed with ochreous; one is placed at the extreme base, two are above the cell, two in the cell, another partly closing the cell, and four below. Palpi black. Head black, with the eyes white-ringed. Abdomen ochreous fuscous, with a black spot on each segment below. Legs black with white spots. Antenne black. Female. Differs from the male in that the subapical band on the fore wing is the same shade of reddish ochreous as the inner marginal area and the hind wing. On the fore wing the ochreous area 1S more compact, and does not extend so near to the base, and on the hind wing the dark apical area is much broader and the conspicuous dusting of the male is absent, whilst the veins for some distance into the dark area are ochreous, those in the male being fuscous well into the ochreous area. On the under side it differs only from that of the male by the less extensive ochreous area and the concolorous subapical band on the fore wing. Expanse, male 22 inches, female 2,5 inches. Hab.

The type of M, darwinia is now in the Tring Museum. Although obviously Acreeine in appearance I am unable to find any species in that group which it is exactly like. PSEUDERESIA MINIUM, sp.n. (Plate XX XIII. figs. 6 g,7 2.) Male. Upper side: fore wing uniform dark blackish brown, without markings. Hind wing bright orange-red with the apex and outer margin broadly and evenly dark brown; the inner margin is narrowly and evenly dark brown. The basal area has several elongate dark brown markings, some of which are confluent. Cilia whitish, brown at the termination of the nervules. Under side: both wings silvery brown, with the central areas shading to dark brown. Fore wing with a brown mark in the middle of the cell and another, larger, at the end. Hind wing with several small red spots near the base, and a curved discal band of five bright red spots, commencing on the costa and reaching almost to the inner margin.

Male. Allied to the preceding P. miniwm, but much smaller. Upper side differs from that species by the inner margin of hind wing being broadly bordered with dark brown blotches from the base to the anal angle. The under side differs from that of P. minium by the brown shading over the central areas being more extensive and by the possession of one red spot on the discal area of the hind wing, placed at the end of the cell. There are also several minute red dots near the base and one in cell 1. Expanse 1 inch. Hab. Bitje, Ja river, Cameroons, 2000 ft., wet season (G. L. Bates). . Type, Mus. Druce. This may prove to be a variety of P. miniwm, but the under side of the hind wing is so differently marked that for the present I prefer to consider it distinct. It is also a much smaller insect. PSEUDERESIA RUSSULUS, sp. n. (Plate XX XIII. fig. 8, 3.) Male. Upper side: fore wing clear orange-red ; the basal and apical areas broadly dark brown, tapering to a point at the angle. Cell wholly dark brown. Hind wing clear orange-red, a black streak partially closing the cell; basal, inner and outer marginal borders rather broadly dark brown. Cilia of fore wing brown, of hind wing whitish between the nervules. Under side: fore wing—costa, apex and outer margin dull brownish yellow, dusted with dark brown scales, thickest on the veins; basal area black, with several deeper spots in the cell; discal area orange-red, becoming paler towards the inner margin; a subapical black band reaching across the wing. Hind wing brownish yellow, dusted with brown along the costa; basal area with eight distinct black spots of varying sizes; an irregular submarginal black band enclosing a row of whitish triangular lunules, and a marginal row of yellow lunules.

Upper side: fore wing cream-colour, darker than L. lircea Hew.*, with the costa very narrowly and the apex and outer margins rather broadly and unevenly blackish brown; a slight indication of a blackish-brown tooth on the costa opposite the end of the cell. Hind wing cream, with the black spots of the under side showing through; outer margin rather broadly blackish brown, inwardly dentate. Cilia of both wings creamy. Under side cream-colour ; fore wing with the apex and outer margin blackish brown as on upper side, the costa, from the base to the clearly defined black tooth on the costa, dusted with blackish brown. Hind wing with outer margin brown as on - upper side, inwardly bordered with a submarginal row of darker brown large spots. A small black spot near the centre of cell 1. Thorax fuscous above. Abdomen cream above and below. Legs yellow dusted with black scales. Palpi yellow tipped with black. Female.

Bitje, Ja river, Cameroons, 2000 ft., dry and wet seasons (G. L. Bates). Types, Mus. Druce. Described from eight specimens. Amongst the wet season examples is a female in which the dark outer margin of the hind wing on both surfaces is reduced to an anteciliary line, and on the under side the submarginal row of spots is almost obsolete as also is the dark apex to the fore wing. May prove to be a form of L. lircea. LarinopoDA EMILIA Suffert. Larinopoda emilia Suffert, ‘ Ivis, xvii. p. 48 (1904); H. H. Druce, Ill. Afr. Lye. pl. i. figs. 1, 1 a (1910). Hab.

It is very difficult to arrive at a correct conclusion with regard to the insects of this genus. Professor Poulton has recently received a series from Lagos which contains examples of the broad bordered form (Z. aspidos mihi), the typical L. lagyra Hew., and the form with the submarginal row of spots on the hind wing below, named by me L. brenda, from Benin. This latter I am now inclined to consider an aberration. It seems quite possible that there is only one white variable species of Larinopoda, as the black cell-spot on the under side of the hind wing of L. ewrema Plotz is sometimes nearly obsolete, and this spot constitutes its only distinction, specimens from Sierra Leone and from Addah having a broad dark border to the hind wing almost as in LZ. aspidos. It will be interesting to know the result of an examination of the ancillary appendages. LiprENA PEROBSOURA, sp.n. (Plate XX XIII. fig. 13, 2.) Female. Upper side: fore wing pale creamy white, costa, upper half of cell, apex, and outer margin broadly blackish brown ; a_ small brown spot at the end of the cell.

(Plate XXXYV. fig. 1, ¢.) Male. Upper side: both wings uniform creamy white with a faint greenish tinge, slightly opalescent at the base of the hind wing. The basal half of the costal margin of the fore wing is pale brown, merging into the blackish-brown apical and outer margins. Under side pale opalescent greenish white without markings, but slightly yellowish over the discal area of fore wing. Cilia of both wings on both surfaces fuscous except towards the apex of the hind wing, where it is white. Thorax clothed with white hairs; abdomen yellowish white above and below.

Oni, 70 m. east of Lagos, W. Africa (W. A. Lamborn) *. Type, Hope Coll., Oxford University Museum. The specimen described above has a number of small black spots irregularly placed over the dark apical area of the upper side of the fore wing, but as those on the right wing are not placed in the same position as those on the left wing, I am inclined to believe that they are due to some external cause. The outer margin of the hind wing has, on both surfaces, a few brown scales which seem to point to the fact that it has lost, or is acquiring, a dark marginal border. The insect’s Pierine appearance is very marked, and Mr, Lamborn is to be congratulated on a very interesting capture. EPIToLa BATESI, sp.n. (Plate XXXIV. figs. 2 ¢,3 9.) Male.

Boutznerr, M.A., F.Z.S., - -King’s College, Cambridge. [Received January 10, 1910. | (Text-figures 37 & 38.) I. Introductory. Some little while ago, when engaged in dissecting some African toads of the genus bufo, Mr. EH. Degen, F.Z.S., noticed that certain specimens possessed curious gland-like deposits of fat between the skin and ventral body-wall of the abdominal region. He was so kind as to call my attention to these structures, and I came to the conclusion that it would be of interest to more fully investi- gate this point in Batrachian anatomy. Examination of specimens of Bufo regularis obtained by Dr. Cunnington and myself from the Fayam province of Egypt showed similar fat-bodies to be present in this species and induced me to examine other allied toads, many of which were found to possess analogous deposits of fat. I was able to dissect a large number of adequate representatives of various species of Bufo. For this my grateful acknowledgments are mainly due to my father, Mr. G. A. Boulenger, F.R.S., who allowed me to examine numerous duplicates from the col- lections under his care at the British Museum. To Dr. F. Werner, of Vienna, I am indebted for a number of living specimens of the Huropean Green Toad, Bufo viridis. The very rare occurrence of adipose tissue in connection with the muscular system of Batrachia has often been commented on ; thus Ant. Dugés (1) in his classical work on the myology and osteology of Batrachians, published in 1835, made the following generalization in his definition of the group :—“ Une particularité dés longtemps remarquée c’est Visolement réciproque des muscles et dela peau, di a l’absence du pannicule graisseux dont on trouve &peine quelques paquets autour du cou chez les sujets 4 grand embonpoint.” Corpora adiposa below the skin are, however, not quite unknown. cue The most recent contribution to our knowledge of this subject is to be found in a paper by F. E. Beddard (7) on the anatomy of the Engystomatid Hemisus, the author describing a pair of conspicuous fat-bodies in lymph-sacs in the iliac region. These structures are lobulated masses of fat of considerable size, in 380 MR. C. L. BOULENGER ON FAT-BODIES [ Feb. 15, appearance resembling the well-known abdominal fat-bodies at the anterior end of the gonads. Similar fat-bodies are described as occurring in the neck-region and are probably connected with the thymus glands*. ; The following brief remark by Leydig (2) shows that the presence of these bodies in Bufo had not escaped the attention of this accomplished investigator, who, however, abstains from any allusion to their structure: “ Die Fettkorper in der Achsel- grube und Weichengegend waren bei calamita rothgelb, bei variabilis graugelb, welche Farbenabinderung wohl nur in den verschiedenen Fiillung der Blutgefasse gesucht werden darf.” Text-fig. 37. Bufo viridis, 2. Ventral view, with the skin reflected to show the position of the subcutaneous fat-bodies. FB. Fat-body. A.V. Ventral abdominal vein. C.V. Cutaneous vein. * These fat-bodies were noticed by Cope (8) so long ago as 1889, a fact which Mr. Beddard seems to have overlooked. In that author’s description of Hemisus (‘ Batrachia of North America’ p. 383) we find the following remarks :— “This genus exhibits also an external corpus adiposum which I have not found in Callula, Engystoma, or any other genus of Batrachia. Each one is subtrihedral, the apex resting near the coracoid, the ee £038 between the strata of the external and internal oblique muscles .. . 1910.] IN TOADS OF THE GENUS BUFO. 381 II. The Abdominal Fat- Bodies of Bufo viridis. The fat-bodies which I am about to describe are very well developed in the common European Bufo viridis, fresh material of which I had the opportunity of examining; it will, therefore, be well to preface my remarks with an account of their structure in this form. On reflecting the skin from the ventral surface of a specimen of B. viridis, one cannot fail to notice a pair of gland- like, fatty structures at the junction of the hind limbs with the trunk. These corpora adiposa, which are present in both sexes and vary considerably both in size and colour in different individuals, are quite constant in position; each extends for a considerable distance along the face of the septum inguinale which separates the abdominal and femoral lymph-saes.

ZOOLOGICAL SOCIETY OF LONDON. THE ZOOLOGICAL RECORD. HE object of the ZoonoeicaL Recorp is to give, by means of an annual Volume, complete lists of the Works and Publications relating to Zoology in all its branches that have appeared during the year preceding the issue of the Volume, together with full information as to the points they deal with, arranged in such a manner as to serve as an Index to the literature of Zoology in all parts of the globe, and thus to form a repertory that will retain its value for the Student in future years. The ‘ Zoological Record’ having been amalgamated with the International Catalogue of Scientific Literature, Zoology, Volumes from 43 onwards can now be obtained only from Messrs. Harrison & Sons, except when purchasing complete sets from the Zoological Society. Under the scheme of amalgamation, Fellows of the Society, and Institutions already on the subscription-list, have the privilege of subscribing at the old rate of 30s. per annum, which covers the cost of carriage of the volume. The subscription becomes due on July 1st. in each year, and lapsesif not paid by the Ist. of December following.

Tue scientific publications of the Zoological Society of London are of two kinds—“ Proceedings,” published in an octavo form, and “‘ Transactions,” in quarto. According to the present arrangements, the ‘‘ Proceedings” contain not only notices of all business transacted at the scien- tific meetings, but also all the papers read at such meetings and recommended to be published in the “ Proceedings” by the Committee of Publication. A large number of coloured plates and engravings are issued in the volumes of the *“ Proceedings,” to illustrate the new or otherwise remark- able species of animals described therein. Amongst such illustrations, figures of the new or rare species acquired in a living state for the Society’s Gardens are often given. The “ Proceedings”’ for each year are issued in four parts, on the first of the months of June, August, October, and April, the part published in April completing the volume for the last half of the preceding year. JT'rom January 1901 they have been issued as two half-yearly volumes. The ‘‘ Transactions” contain such of the communications made to the scientific meetings of the Society as, on account of the nature of the plates required to illustrate them, are better adapted for publication in the quarto form. They are issued at irregular intervals. Fellows and Corresponding Members, upon payment of a Subscription of One Guinea before the day of the Anni- versary Meeting in each year, are entitled to receive the Society’s Publications for the year. They are likewise entitled to purchase the Publications of the Society at 25 per cent. less than the price charged for them to the Public. A further reduction of 25 per cent. is made upon purchases of Publications issued prior to 1881, if they exceed the value of five pounds. Fellows also have the privilege of subscribing to the Annual Volume of the Zoological Record for a sum of 30s. (which includes cost of delivery), payable on the 1st. of July in each year; but this privilege is forfeited unless the subscription be paid before the Ist. of December following. The following is a complete list of the publications of the Society already issued. TRANSACTIONS* OF THE ZOOLOGICAL SOCIETY OF LONDON. 4to. 19 vols. and Index Bee Ee hp tis Fellows. Public.

Burienp, M.A. (Camb.), B.Sc. (Lond.), late Scholar of Christ’s. College, Cambridge; Assistant Lecturer and Demonstrator in Zoology, University College, Cardiff.* | Received February 12, 1918. } (Text-figures 40-53.) Introduction. The study of the structure of the Chimzeroids is full of interest on account of the diversity of opinion which exists with regard to the relationship of the Holocephali to the Elasmobranchii. Although retaining many primitive characters in the skeleton, brain, sense-organs, and viscera, the Holocephali have nevertheless acquired very specialised structures presumably associated with their occurrence and mede of life. Referring more particularly to the urogenital organs and their accessory parts, the Chimeroid is unique among Fishes in the possession in the male of a pair of “middle claspers,’—regarded by 'T. J. Parker (1886) as a rudi- mentary third pair of limbs,—and in the female of a so-called ‘“‘yreceptaculum seminis,” mentioned by Leydig (1851) and by subsequent writers. Notwithstanding the excellent contributions of Leydig and Hyrtl over fifty years ago, and the more recent work of Mazza and Redeke, it was felt that a more detailed account, with figures, of the urogenital organs of Chimera is not readily accessible to English readers, and it was to supply this want that the work was primarily undertaken. Further investigation showed that the published accounts were at variance on points of the first importance, and this fact can now be attributed to: (1) the use of imperfectly preserved material, and (2) the structural dif- ferences existing between animals which are immature and those * Communicated by Professor W. N. Parker, Ph.D., F.Z.S. 1910.] ORGANS OF THE FISH CHIMERA MONSTROSA. 511 which have attained sexual maturity. With the material at my disposal I have been able to make additions to the above accounts and also to verify much of the early work which some later writers have in part disputed. My best thanks are due to Professor W. N. Parker of this College, who suggested the work and rendered me much assistance by his friendly criticism and advice in the course of these investigations. A preliminary account of the relations of the vasa efferentia has already appeared under our joint names (15). Historical. Leydig (1851) described the urogenital system of Chimera monstrosa, both male and female. He observed the network of small ducts on the ventral surface of the testis and the manner in which these minute ducts unite {o form the larger ducts—vasa efferentia—which are directed towards the ‘‘ Nebenhoden” or coiled anterior portion of the sperm-duct. The different regions of the sperm-duct are described, though not by the aid of trans- verse sections, but by dissection only. Moreover, Leydig’s work is very important in that he differentiates in the male the posterior brown kidney from the anterior white structure called by Hyrtl the “ Leydig’s gland,” and he examined the secretion from this latter. The author concluded that it must be regarded as an accessory genital gland. In his account of the female organs Leydig made special reference to the “shell gland ” and “uterus” of the oviduct, and looked upon the “ digitiform gland”—the ‘“‘receptaculum seminis” of later writers—as most probably an accessory female genital gland. Hyrtl (1853) continued Leydig’s work on Chimera, although he was not so fortunate in obtaining fresh material. He could not decide whether the cavity dorsal to the peritoneum between testis and ‘‘ Nebenhoden ” was a lymph sinus, or whether it was in connection with the anterior coiled end of the sperm-duct and consequently a coelomic intermediary between the testis and its duct. Both Leydig and Hyrtl believed that vasa efferentia must be present, but could not locate them with accuracy, nor determine their relation with the sperm-duct. Hyrtl regarded the most anterior duct from the Leydig’s gland as the real beginning of the sperm-duct: the “digitiform gland” was held to be a reservoir for the reception of the sperms of the male. Mazza (1894) believes that the testis is not connected with its “‘ Nebenhoden,” the spermatozoa from the former reaching it by first passing into a portion of the body cavity and thence getting into the coiled anterior end of the sperm-duct by means of canals (¢ mesonephric tubules). Redeke (1898) does not throw any light on this point. He divides the kidney into cranial, median, and caudal zones; but this distinction is untenable, since the cranial zone as indicated in his figures is in reality the anterior coiled end of the sperm-duct, 512 MR. T. H. BURLEND ON THE UROGENITAL [Mar. 1, the median zone is Leydig’s gland, and the caudal zone alone is excretory in the adult male. The author emphasizes the primitive nature of the kidney on account of its marked metamerism, and apparently believes that the sexual portion of the Selachian kidney 1s absent. Bashford Dean (1906) does not recognise any “ Geschlechtsniere.” W. N. Parker and T. H. Burlend (1909) show the relation between vasa efferentia and sperm-duct, the former uniting to give a longitudinal duct which is directly continuous with the coiled sperm-duct, so that the sexual part of the kidney or “‘ Geschiechtsniere” is represented in the adult male by the “ rete testis.” Attention is also directed to the unsatisfactory use of the term ‘ epididymis.” Material and Observations. Tam indebted to Mr. J. J. Neale of Cardiff for much valuable material. The Chimeras, both young and adult, male and female, had been carefully packed in ice and arrived at the laboratory in excellent condition. The alimentary canal having been removed, the whole urogenital region was fixed in corrosive sublimate, 90 per cent. alcohol or 5 per cent. formalin ; but the first of these reagents proved the most satisfactory for histological work, the formalin-preserved specimens being most suitable for dissection. Many of the regions were sectioned, and this was especially difficult in the coiled sperm-duct region owing to the slow rate of penetration by the successive reagents. Weigert’s Hematoxylin was used for staining in bulk, and Delafield’s or Hhrlich’s acid Hematoxylin for staining on the slide; the Cambridge rocking microtome was used in sectioning.

It is a spherical knob-hke organ bearing recurved spines ventrally, borne on a short thick stalk directed forwards; the whole organ is capable of being depressed into a shallow pit immediately in front of it and so of becoming less conspicuous. The middle claspers are wing-like structures practically hidden away in pouches situated at the anterior limit of the pelvic-fin skeleton. In the extended condition they are seen to have cartilaginous supports bearing a row of from 5-7 forwardly pro- jecting spines on the edge nearest the ventral middle le. In text-fig. 40 the left middle clasper is shown everted, m.cl., the clasper on the right side being indicated in the normal position.

(b) Testes, vasa efferentia, sperm-ducts, and glands of Leydig.— The bean-shaped testes attain a length of from 14 to 2 inches in the well-developed male adult, and are suspended from the dorsal body-wall by peritoneum in the anterior region of the abdominal cavity. The peritoneum also covers the ventral surface of the corresponding Leydig’s gland and sperm-duct, but not their dorsal surfaces, whereas it closely invests each testis and then passes over the neighbouring body-wall. In the centre of the dorsal surface of the testis there is a crescent-shaped flap of lymphoid tissue, between which and the imner border of the testis the peritoneum is not contiguous, and so a space is left between the latter and the testis (text-fig. 41, ¢./.). The ventral surface of the gonad in the fresh condition presents a white cortical and a greenish medullary area; beneath the peritoneum of the latter a network of minute vessels may be detected by the aid of a lens (text-fig. 40, v.eft.). These are continuous with the testis crypts and are filled with spermatozoa. They unite to form larger vessels, the whole network—rete testis —ultimately giving rise to six vasa efferentia, which are directed towards the anteriorly coiled sperm-duct on the inner side of the testis. After traversing, on the dorsal side of the peritoneum, the space between the gonad and its duct, they pass into a longi- tudinal collecting duct, the most posterior of the vasa efferentia, however, being an exception, since it never reaches the above- mentioned duct but ends blindly in the peritoneum. The collector passes forwards and gradually sinks in between the numerous coils of the sperm-duct of this region, but then bifurcates, and the two ducts formed proceed some short distance before finally fusing to establish the Leydig’s duct or sperm-duct by an increase in diameter, but in the nature of the lning epithelium and contents identical with the collecting duct. The sperm-duct does not pass directly backwards but forms a conspicuous much coiled structure which more posteriorly becomes less intricate, so that its winding course may be followed. After this, the diameter of the duct greatly increases and gives rise to a long straight sperm-vesicle, which becomes constricted about one- third of the distance from its posterior end, but enlarges again and ultimately opens near the opening of its fellow on the other side into a much narrower median urogenital sinus (text-fig. 41, Ur .S.)- Running along the inner border of each sperm-duct, and later becoming dorsal to the sperm-vesicles, are two white glands showing distinct traces of metamerism, complete anteriorly but not sc marked at their posterior ends: these are the glands of Leydig, almost ribbon-like in front, but less flattened dorso- ventrally, and much wider behind. They extend from the level of the middle of the testes to the constricted regions of the sperm-vesicles. From each segment of Leydig’s gland in front, there passes off 1910.)

On dissection, the cavity is seen to be partly divided up along the whole length of the vesicula seminalis by thin connective tissue partitions, which are regularly arranged and resemble the septa of an Karthworm, in the anterior region. In the dorsal middle line, however, there is a channel along which the products of the sperm-duct may pass (text-fig. 42, a). In the green region the partitions gradually lose their orderly arrangement; they appear further apart and then present a regular honeyeomb on the inner face of the wall of the sperm- vesicle. Whereas, too, the contents of the anterior white region consist of closely packed spermatozoa along with some secretion from Leydig’s gland, the contents in the green region consist to a large extent of the above secretion with spermatozoa scattered in it (text-fig. 42, 5). The posterior one-third of the seminal vesicle, beyond the constriction, is thick-walled, and the partitions become again repeated regularly, with a series of new partitions running at right angles and in the direction of the length—the contents of the compartments thus formed comprising free spermatozoa mixed with the secretion of Leydig’s gland. The sperm-duct, not noticeable in the green region, now appears as a number of fine inter-communicating ducts, into which the last six ducts from the gland of Leydig empty (text-fig. 42, ¢). Histology of Sperm-Ducts and Glands of Leydig. Sections through the above glands show them to be of uniform structure throughout, viz., long coiled tubules of greater diameter than the urinary tubules, the lining epithelium being columnar and non-urinary, with much secretion containing nucleated material in the lumen. These tubules are continuous with the wider collecting tubes which pass across from the gland to the sperm-duct or seminal vesicle, and which also contain the same secretion as the tubules of Leydig’s gland. No glomeruli are found in the gland. This fact I was able to confirm by mounting thin pieces of the gland stained with hematoxylin and cleared in oil of cloves. This, no doubt, partly accounts for the white appearance of the glands of Leydig as compared with the brown kidney behind. The nature of the contents of the sperm-ducts and sperm- vesicles was ascertained by transverse sections taken through these structures in the regions marked I-VI in text-fig. 41, and illustrated by text-figs. 43-48. Text-fig. 43 is a somewhat diagrammatic representation of a section through region I of text-fig. 41. The sperm-duct is much coiled and its cavity is filled with spermatozoa, mostly free, although there is a tendency towards aggregation in some of the coils. In region II] Leydig’s gland is larger and the sperm-duct no 518 MR. T. H. BURLEND ON THE UROGENITAL [ Mar. 1, longer coiled. The latter contains free spermatozoa which fill the entire lumen and yet are not massed together into bundles (spermatophores) (text-fig. 44).

In region III of text-fig. 41 or region a of text-fig. 42 the horizontal partitions (par. in text-fig. 45) are cut rather obliquely, and the spaces between are occupied by spermatozoa aggregated apparently into spermatophores, with a sparse admixture of the secretion from Leydig’s gland. In the passage (sp.) along the dorsal middle line of the cavity, the spermatozoa are free and in the condition found in the sperm-duct. A section across the sperm-vesicle in region IV of text-fig. 41 or region 6 of text-fig. 42 presents the structure indicated in text- fig. 46 (p. 520).

In the vesicle wall now appear numerous diverticula sp." containing loose free spermatozoa and nucleated material secreted by the gland of Leydig. Lastly, in the posterior region of the sperm-vesicle (marked VI in text-fig. 41) the structure aa. is absent, due to the dilatation of its channels, their fusion with one another, and the formation of a cavity into which the diverticula of the sperm-vesicle wall open (text-fig. 48). The diverticula contain peripherally (between the thick partitions) spermatozoa mixed with nucleated matter, whereas the central cavity contains free and widely separated spermatozoa floating in albuminous material in great abundance. 520 MR.

In the middle region (pale green), the spermatozoa are thoroughly mixed with “the secretion of Leydig’s gland, while the posterior part of the vesicle serves as a receptacle where the free spermatozoa are collected, and most probably also nourished, by the above secretion.

Sperm-sacs.—No trace of these structures is fownd, and this is to be expected if the sperm-sacs are formed from the lower ends of the Miillerian ducts (see Borcea, 13), for the Millertan ducts of the male Chimera persist, although in an undeveloped condition (see below). Urinary Organs. The glands of Leydig pass posteriorly into the true kidney, which consists of right and left halves, partly separated by con- nective tissue in front, but completely fused behind into a median brownish-red structure situated dorsal to the ends of the seminal vesicles. The kidney ends posteriorly in a conical portion, which extends beyond the caudal lmit of the abdominal cavity. It is drained by six pairs of ureters which open together into the uro- 522 MR. T. H. BURLEND ON THE UROGENITAL [Mar. 1, genital sinus by two apertures situated behind those of the sperm-ducts (text fig. 42, wr.o.). Histology. —In section the kidney presents typical excretory tubules (not so large as the tubules in Leydig’s gland), with numerous well-developed glomeruli in the dorsal region. More- over, the ureters do not contain nucleated material such as is found in the ducts draining Leydig’s gland. Urogemtal Sinus. The median rather narrow urogenital sinus receives the sperm- duct and urinary openings at its front end, and passes dorsal to the rectum to end in a flask-shaped, somewhat laterally com- pressed structure, into the ventral wall of which the ends of the Mullerian ducts pass close together. The sinus opens on the apex of a median papilla behind the anus, and between the bases of the posterior claspers. Hence the cloaca, usually found in male Elasmobranchs, is absent in Chimera. Two abdominal pores situated on the latero-posterior margins of the anus put the abdominal cavity in connection with the exterior. Mullerian Ducts. Mere traces of the Millerian ducts are to be found persisting in most adult male Elasmobranchs, but the male Chimera possesses them in the most perfect condition. They appear as narrow tubes running between testis and coiled sperm-duct of each side, and further back, on the outer border of the sperm-vesicle; they end blindly behind in the wall of the urogenital sinus, but open into the ccelom anteriorly by slit-like openings, quite an inch apart, situated on the posterior surface of the wall dividing the pericardial cavity from the general body- cavity.

They are invested with peritoneum, which also forms a ventral covering for the corresponding Miillerian duct, sperm-duct and kidney lying adjacent. In transverse sections it is possible to make out a number of efferent ducts passing into a collecting duct, which gradually passes into the coiled sperm-duct, and so the vasa efferentia and sperm-duct have the same relation as in the adult. No kidney tubules intervene, and the lining of the former (efferent ducts) imperceptibly passes into the lining found in the latter. The anterior coiled end of each sperm-duct is, even at this period, much coiled and of greater size than the testes; at a level a little behind the latter it is but little coiled and rather wider, and then passes practically straight back along the outer border of the kidney until this joins its fellow of the other side, at which level it passes ventral to the now wide and deep kidney to fuse with the other sperm-duct in the middle line. It should be noticed that in its posterior region the sperm-duct is still of uniform diameter, the later changes to produce the seminal vesicle being not yet apparent; further, ducts pass off to the sperm-duct at intervals along the whole length of the paired portion of the kidney, with the possible exception of the first one or two segments. Behind, the unpaired kidney is drained by six ureters arising from either side, and opening separately, though very close together, into the respective sperm-ducts just before the latter fuse and open into the urogenital sinus. Urinary Organs. These consist of a posterior brownish unpaired portion re- presenting the adult kidney, and two ribbon-like paired brownish bands, extending forwards to a level immediately in front of the testes, with regular segmentation, and short ducts passing into the sperm-ducts as described above. With the exception of the first one or two segments—which appear degenerate—the kidney possesses numerous glomeruli, as may be ascertained by staining and clearing in oil of cloves. Hach segment of the kidney—and the segmentation, especially anteriorly, is very noticeable— apparently consists of much coiled tubules with two or three or even more glomeruli in the dorsal region. From the position and relations of the paired portions of the kidney, it is evident that later they loose their glomeruli and give rise to the glands of Leydig of the mature male adult. Urogenital Sinus. There is no trace of sperm-sacs, but the chamber formed by the fusion of the two sperm-ducts widens, and receives the two Millerian ducts, which apparently pass in close together in the ventral middle line about half-way along its length. The Miillerian ducts are not in open connection, however, with the sinus, nor do they ever become so. DX bo nr T3104 ORGANS OF THE FISH CHIMMRA MONSTROSA. Millerian Ducts. At this stage the ducts of Miller surpass in diameter the sperm- ducts, and appear as tubes running in the peritoneum along the outer border of each half of the kidney, then between the testes and coiled sperm-ducts to meet anterior ly in the middle line, and open by a common aperture into the celom, Their lining 1s thrown into folds in some regions. Abdominal pores, situated “at the posterior margin of the anus, are both present and open. ApuuT FEMALE CHlL£RA MONSTROSA, Tn the adult condition the female Chimera is somewhat larger than the male in size and general proportions. In all external characters (except in the absence of clasper s) the female resembles the male, but differs from it in the possession of a longitudinal shallow groove in the ventral middle line of the body, a little distance behind the urogenital openings. This fleshy groove is bordered by skin white in appearance; it is lined with elongated glandular cells, extends for a distance of from 23 to 33 inches, and is nearly + i inch deep. The urogenital organs—just as in the male —extend the whole length of the abdominal cavity and eonsist of two ovaries, two oviducts with shell-glands, kidney (paired and unpaired regions) with ureters and urinary Teledidlex ; and lastly, 2 median so-called ‘‘ receptaculum seminis.” Genital Organs. The two ovaries are situated one on each side of the dorsal middle line of the abdominal cavity, suspended by the mesovarium, and situated anterior to the front end of the kidney. Irregular in outline and easily ruptured, they present a lobulated appearance due to the Graafian follicles, some of which are very large (text-fig. 50). The oviducts are extremely prominent tubes differentiated into regions, opening anteriorly on the posterior aspect of the peri- eardial wall and in front of the liver by a single large median ceelomie opening, by which the eggs liberated from the ovaries gain access to the oviducts, For the first one-third or one quarter of their length the oviducts are of comparatively small diameter, but then rapidly imerease to form the shell-glands. These almost spherical structures are external to and at the level of the ovaries, and are lined by long glandular epithelial cells which are elevated to form a circular ridge on the inner surface of the wall; this ridge in a fresh specimen appears white against the rest of the wall of the gland. The succeeding quarter of the oviduct resembles the first quarter in diameter, after which the oviduct gradually increases in width ; 526 MR. 'T. 1.

The latter are strap- shaped structures with indications of segmentation, especially anteriorly, where they diminish im size, the front end being situated about the level of the shell-glands and the posterior margin of the ovaries. By careful dissection the peritoneum covering the most anterior isolated segments may be removed, and they are then seen to lie on each side of the dorsal aorta. The paired portions of the urimary organ pass into a single median unpaired part behind, which is wide, deep, and triangular 528 MR, T. H. BURLEND ON THE UROGENITAL [Mar. 1, in section, with but little signs of segmentation, and terminated posteriorly by a conical portion, which projects caudalwards some distance behind the abdominal cavity. The paired and unpaired regions are of a uniform reddish-brown colour, and have glomeruli present throughout. Short collecting ducts pass from the lower outer borders of the segments in front, and, at intervals, from the less segmented parts of the urinary organ behind, into a longitudinal duct running along the outer margin of the paired portions, this duct extending in the peritoneum anteriorly beyond the level of the kidney, and apparently becoming attenuated and ending blindly. The longitudinal duct of each side passes, along with six ureters from each side of the unpaired urinary organ, to open dorsally by a right and a left opening into a median large urinary bladder. The region where these ducts open is about one-third of an inch from the front blind end of the bladder ; the latter becomes somewhat narrower and opens behind the oviducal openings by a median aperture at the caudal end of the ridge-like elevation described above. Hence there is no cloaca, the only indication of such being the depression between the bases of the pelvic fins, where genital and urinary organs and intestine open. It seems probable, having regard to the rudimentary nature of the front end of the urinary organ in the adult female, and the forward prolongation of the longitudinal collecting duct beyond it, and further, the fact that the kidney extends beyond the ovaries anteriorly in the immature female, that the front end of the adult female kidney has undergone degeneration. The rectum opens separately and about an inch in front of the oviducal apertures; the anus has on its postero-lateral margins the abdominal pore openings, which have the same relations as in the male. “ Receptaculum Senunis.” In the ventral middle line and almost mid-way between the anus and the urinary aperture is an opening, quite prominent and just in front of the oviducal openings, which leads into a digitiform, thick muscular-walled sac, about an inch in length and called by writers from the time of Hyrtl “ receptaculum seminis.” A further study of this structure shows that the above name is misleading, and that a better term would be “ digitiform gland.” On examination no spermatozoa were found among its contents, but a fluid containing only globules and a large brown chitinous rod occupied the greater portion of its lumen. In all the adult females examined this rod was present, but no spermatozoa. The lining of this sac consists of long epithelial glandular cells. 1910.] ORGANS OF THE FISH CHIM4RA MONSTROSA. 529 Youneé FEMALE Cy7a7er 1.

Genital Organs. The ovaries are slightly biconvex oval structures similar in size and position to the spermaries of the immature male, but having an uneven surface already, due to the presence of ova of varying size. They are intimately associated, by means of the covering peritoneum, with the oviducts in the region of the future shell-glands, but are on the outer sides of the oviducts, and not median to them as is the ease in the adult. The oviducts closely resemble the Miillerian ducts in the immature male, being almost uniform in diameter, and having acommon median coelomic opening in front, below the cesophagus. There is but a slight swelling in the shell-gland region, but further back the uterine swollen portion is already evident; the enlarged lower ends of the oviducts open separately into a median common urogenital sinus. Anteriorly the lining of the tubular oviducts is glandular and raised into longitudinal folds. Urinary Organs. The kidney is of a uniform brown colour, segmented in front, but less markedly so behind: it consists of right and left halves which are fused together for a short distance posteriorly, in which region the organ is triangular in cross section, whereas further forward each half is strap-shaped. Glomeruli are present in twos and threes or even more in each segment. From the posterior outer border of each segment there passes off a short duct which joins a longitudinal collecting duct, which in turn arises at the front end of each half; these ducts open close together into a median urinary bladder as in the adult, Moreover, some five or six of these ducts, on each side of the posterior region otf the kidney, delay their point of opening into the main longitudinal ducts and only pass in just before the latter reach the bladder: these become the special ureters in the mature animal. In the female the attenuation of the kidney anteriorly is not so noticeable as in the young male, although sections show that the extreme front of the immature female kidney has lost its glomeruli and that its tubules are degenerating; and thus we find Proc.

Its lining is glandular and it opens into the urogenital sinus by a median opening in front of the ovidueal openings. The rod-like chitinous structure present in all adult females is absent, and so has not yet been secreted by its lining. Urogenital Sinus. This structure is well-marked in the young female: it receives in front the opening of the ‘“receptaculum seminis,” then the two oviducts open laterally further back, but a little in front of the median smaller aperture of the urinary bladder. ‘The sinus opens on a median papilla situated a short distance behind the anus, and reminds one of the urogenital aperture of the male in appearance and position. In the further development of the female the urogenital sinus opening gets larger and larger until the sinus is represented in the adult “merel y bya depression with two deep pouches bordering the ovidueal openings anteriorly. The anus and abdominal pores do not differ from the condition found in the adult. A young female Callorhynchus I exainined by means of sections (kidney lent to me by Prof. W. N. Parker) showed the same general arrangement of the urogenital organs. The ovaries are comparatively short and the kidney extends further forwards. The oviducts have a single median opening into the ceelom, a uniform diameter throughout, with no swollen uterine portion at this stage, and open separately immediately dorsal to the anus into a distinct cloaca. There is no sign of a ‘“‘receptaculum seminis”’ or urogenital sinus. The abdominal pores are imperforate as yet. The kidney possesses glomeruli throughout: it is at this stage of uniform section, mad the main ee on each side receives about four small ducts from each half of the kidney in front ; the remaining five to seven small ducts from each side are posterior and enter the bladder along with the main ureter. SUMMARY AND CONCLUSIONS. The following points relating to the above description deserve special notice :— (1) The urinary organ of the young male differentiates in the adult into anterior paired Leydig’s glands and_ posterior unpaired kidney. (2) The glands of Leydig do not function as a renal organ as is shown by their histology and the contents of their ducts; further, the condition of the spermatozoa at intervals in the long coiled sperm-ducts (Leydig’s duets) renders it probable that the 1910. | ORGANS OF THE FISH CHIMHRA MONSTROSA. 533 function of the glands of Leydig is the secreting of a fluid for giving nutrition to the spermatozoa. (3) The sexual kidney or ‘“Geschlechtsniere” is represented in the adult male only by the rete testes, efferent ducts, and longitudinal collecting duct. Moreover, an epididymis, as usually defined, is absent. (4) The development of the glands of Leydig is accompanied by changes in the sperm-ducts, and the formation of highly complex sperm-vesicles. (5) The anterior region of the urimary organ undergoes a retrograde development, as is shown by a comparison of this structure in the immature and adult females. 6) There is a distinct urogenital sinus in the young female, which does not persist in the adult. (7) The application of the term “ receptaculum seminis” to the digitiform gland found ventral to the urinary bladder is erroneous, and this structure must for the present be regarded as a female accessory genital gland of obscure function.

The Secretary read the following account, by E. W. Shann, B.Sc., of the Gatty Marine Laboratory, St. Andrews, of some post-mortem phenomena ebserved in a Lemur. Harly in the morning of February 23rd, 1910, a speciinen of Lemuw fulous rufifrons was found apparently dead in its cage in the Zoological Gardens at Giza, Egypt. The specimen had been kept in the Gardens for upwards of nine years. At 9 A.M. the animal was examined by Mr. M. J. Nicoll, Assistant Director. It was lying limp on the sand,.for the limbs had not stiffened. At irregular intervals the mouth opened slightly, and an almost imperceptible motion passed through the thoracic region, Mr. Nicoll says that lemurs and some monkeys not infrequently undergo a more or less protracted moribund condition before death actually occurs. This is particularly the case with old specimens, and no case is known in which the animal has recovered from this condition. At 11 a.m. Capt. $. 5. Flower, Director, gave the lemur to the present writer for the purpose of dissection. By this time there was no movement of the jaws, but the limbs were still limp. After a few minutes the gasping recommenced. This may have been due to the warmth of the hand. Dissection was postponed, . and Mr. Nicoll tried the effects of artificial respiration. The gasping became more frequent, and at fairly regular intervals of 40-50 seconds. No heart action could be detected. The spas- modic movements again died away. The eyes had a glazed appearance, but as the animal had been blind for a considerable peviod, this was no clue to its condition. At 2 p.m. the eyelids were found to be closed, and there was no mevement of the jaws. Dissection was commenced. It was observed that the blood flowed slowly from a slit in the jugular vein; that is to say, the blood was not congealed. The limbs were still limp. On opening the costal region a muscular con- traction of the heart was noticed. After touching the heart with the handle of a scalpel further contractions took place, and continued for more than a minute. At4 p.m. this heart action was observed by Capt. Flower. The dissected lemur was then left, covered with a damp cloth, till 6.30 p.m. when it was again examined by Capt. Flower, Mr. Nicoll, and the writer. The muscular contractions of the heart were very evident, though the limbs were rigid by this time. Further observations were made at 9 p.m., 10.15 p.m., 11.15 p.m., and 1 4.m., the following day. The contractions could be easily induced, but later the response became feebler. At 8.30 A.m—a whole day after the apparent death of the animal—a slight muscular action could still be induced in the auricles, but no longer in the ventricles. By 2 p.m. all motion had ceased. No means were at hand for testing the effect of electricity upon the organ in question. That this is a case of reflex action seems to be the probable 536 ON A NEW POTTO FROM BRITISH EASY AFRICA. | Mar. 15, conclusion ; for, at least in the later phases, the animal was dead, in the generally accepted sense of the word.

Young adult male. B.M. No. 10.3.18.1. Original number 515. Killed 4th Jan., 1910. Presented by Messrs. Maturin and Brett through Mr. R. Kemp. This fine species of Potto was no doubt that from Uganda mentioned by Sir Harry Johnston *, and, with the exception of that mention, represented a considerable extension of the known range of Perodicticus, the genus having been otherwise recorded only from the West Coast. _ P. ibeanus was at once distinguishable from all others by the hoary colour of its back, which contrasted markedly with its blackish shoulders, the difference being due to the long hairs of the former being broadly tipped with ashy, a character not found in any other Potto. Its coat also was of an unusually soft rich nature, in agreement with the considerable elevation of its habitat. The specimen had been given by Messrs. Maturin and Brett to Mr. R. Kemp, who was collecting for the National Museum on behalf of Mr. C. D. Rudd. Mr. D. Seth-Smith, F.Z.S., M.B.0O.U., Curator of Birds, communicated the following account of some living examples, in the Society’s Gardens, of the Black-hooded Parrakeet (Psephotus cucullatus North) :— The Society has recently acquired by exchange a pair of Parra- keets of the genus Psephotus, which were originally obtained from Mr. A. E. Jamrach, who informs me that in all ten pairs arrived in Europe some few months since. These birds were at first believed to be Golden-shouldered Parrakeets (Psephotus chrysopterygius), and a pair was shown at a recent bird-show at the Crystal Palace under this name. In examining the pair, however, I noticed that the male bird lacked the yellow frontal band characteristic of that species, and that the black marking on the head extended to the base of the bill, over the lores and completely surrounded the eye; and moreover, the yellow patch on the wings appeared to be more extensive than in P. chrysopterygius. 1 thought at first that these birds were referable to a species described in the P. Z. 8. of 1898 by Professor Collett as Psephotus dissimilis, but on looking up the description of these I found that the crown is chestnut according to Collett and dark brown according to Harterty. T have since discovered a reference to this black-crowned form in the ‘ Victorian Naturalist’ for 1909, where Mr. North publishes a note, dated Feb. 6, 1909, on these birds, probably the very lot of which the Society’s pair formed part. They were captured by Mr. Fritz Kruger in the Northern Territory of South Australia, 200 miles south-east of Port Darwin, which is the locality P. dissimilis is said to mhabit. * © Uoanda,’ vol. 1. p. 364, 1902. + Noy. Zool. vol. xii. p. 214 (1905). 938 ON PARRAKEETS OF THE GENUS PSEPHOTUS. [ Mar. 15, Mr. North examined them on their arrival in Sydney, and at first believed them to belong to that species, but subsequently noticed the characters to which I have referred. He was able to examine no less than sixteen specimens, five of which were adult males entirely lacking all trace of the brown frontal band that characterises P. dissimilis. He writes, ““ What I regard as the chief point of difference is that not only are the lores, forehead and crown of the head of the adult male black, but that this colour extends down the anterior portion of the cheeks to the base of the lower mandible. Viewed in front, the bird appears to wear a black mask or cowl. Should it prove to be distinct I propose to distinguish it under the name of Psephotus cucullatus, and vernacularly as the Black- hooded Parrakeet.” Head of Psephotus cucullatus North. In the Society’s pair of birds the male is rather rough in plumage at present, but shows quite distinctly the characters above described, and I think there is no doubt that Mr. North is right in ascribing this to a new species. The female of P. cucullatus lacks any trace of the yellowish frontal band which is present in the female of P. chrysopterygius ; but it agrees fairly well with Professor Collett’s description of P. dissimilis. The recent consignment of these Parrakeets does not appear to be the first arrival of P. cucullatws in Europe, for Mr. Blaauw informs me that he has some specimens in his aviary at Hil- versum, Holland, which he received Jast summer. Moreover, a pair of birds received alive by Mrs. Johnstone, of Burrswood, Groombridge, so long ago as 1902 or 1903, of which the skin of 1910. ] ' ON BREEDING OF PINE SNAKES. 539 the female is in my possession, and that of the male in the pos- session of Mr. Fasey, of Snaresbrook, Essex, undoubtedly belong to the race recently described by Mr. North. The Secretary read the following letter which had been sent him by Mr. George Jennison, of the Zoological Gardens, Belle Vue, Manchester :— “We attribute our success in breeding Pine Snakes solely to the provision of a suitable habitat. “The adults were turned into our large snake cage in the beginning of June, and evinced such a desire to enter the conservatory, which for purposes of atmosphere forms part of the cage, that we gratified them by making a small hole through which they could pass. “Some of the boas show a similar preference for the conser- vatory, but to nothing like the same extent as the Pine Snakes. ““They revelled in the rank vegetation. and speedily disappeared below ground in burrows probably of their own construction. There among the soil, which has a temperature of 90° or so, they perfected their family arrangements. ‘“‘ Their success came to us somewhat as a dramatic surprise. “On October 18th, a Pine Snake 13 inches long was discovered on the floor of the greenhouse which adjoins the snake cage. “Tt had passed between the slates that form the bed of the conservatory down among the heating pipes where the temperature would be 100° or more, and thence through a well-worn opening about the size of a mouse hole to the place where it was found. “Seven or eight snakes were collected during the next few days, several being among the heating pipes. All were very lively and in excellent condition. They were similar in colour and pattern to the parents. “‘ Four we put in a cage apart, and the keeper Craythorne says he saw them on several occasions take worms, but they were obviously not doing as well as those left to their own resources, so we returned them to the old home where they immediately disappeared under the soil. Burrowing to such an extent, they are rarely seen, but a specimen captured in good condition on March 7th measured 164 inches, a growth of 34 inches in about four months. “« We have no knowledge of the number of the brood nor one may say of their distribution, as they have been found in good order in our temperate greenhouse twenty yards from their birth- place.” Mr. Charles Sillem exhibited some living specimens of the Crustacean Chirocephalus diaphanus recently caught in a flooded ditch on Eton Wick Common. 540 MR.

The present paper is the outcome of a piece of research, carried out in the Zoological Laboratory of the University of Birmingham, on the skeletal anatomy of the primitive Selachian Chlamydo- selachus anguineus. The work was suggested by the late Prof. Bridge, and a large part of it, that dealing with the skull and vertebral column, was carried out under his supervision. I should like here to say how much I appreciate the opportunity of using such valuable material, and to express my gratitude for the helpful criticism which my late teacher was always willing to give. The material included one perfectly complete male specimen, the greater part of a large female specimen, and the remains of another male, which was principally in the form of parts set up as museum specimens. * Communicated by Dr. P.

In the first place, Chlamydoselachus anguineus is admittedly a primitive member of the Selachian group of fishes, and by virtue of its position, it demands a more considerable knowledge of its structure and anatomy than would be the case were it a member of one of the higher and more specialized groups of Selachians. F urthermore, the original account of the fish given by Garman (10) is in many parts very limited and indefinite, whilst the figures are rather indistinet and in a few cases inaccurate. Little works has been carried out on the anatomy of the skeleton since the publication of this paper. Giinther (14) has dealt with the skeleton of the mixipterygia and with the abdominal viscera. Braus (2 & 3) has dealt with the pelvic plexus in the earlier of the two papers, and in the second one has given a short comparative account of the pectoral girdle and fin and of the mixipterygia. Fiirbringer (6) has described the labial cartilages and the vestigial seventh branchial arch, which were nob discovered by Garman. In addition to these, there is a paper by Ayres (1) on the com- parative anatomy of the arterial system, and two papers by Hawkes (16 & 17), the first on the cranial and spinal nerves, and the second on the abdominal viscera and the vestigial seventh branchial arch. My best thanks are also due to Prof. Gamble for many helpful suggestions during the progress of the work since the death of Prof. Bridge. Il. Measurements.

(Plates XLII., XLITI. figs. 1-6.) My observations on two skulls agree in the more important points with the description given by Garman (10) pp. 7-9. It is not my intention in the present account to redescribe the whole of the structure, but rather to amplify the original de- scription in those points which appear to call for special emphasis, and to make certain additions. JI propose to deal first. with the eranium, then with the first and second visceral arches and their ligaments, and finally with the branchial skeleton and certain other points. a. Cranium (fig. 1). At the extreme anterior end of the cranium is the broad, flat, and somewhat rounded rostrum (7.), which is notched at its sides. Its shape gives to the nasal region a curious truncated appearance. ‘The olfactory capsules (0.c.) are large, rounded, and thin-walled. Their large apertures have the nasal cartilages (2.c.) fitting into them. ach of these is ring-like and has a bar across the middle of the aperture so as to give rise to the double opening which each capsule presents in external appearance. The anterior fontanelle (af) is very large and broad, extending posteriorly to a point almost level with the preor ital process. Immediately behind the olfactory capsule is a deep furrow which communicates above with the foramen transmitting the ophthal- micus branch of the seventh nerve, and in cihieh are found branches of the latter nerve. Posterior to this furrow is a some- what prominent ridge having a sharp edge orbitally, and gradually running into the tapering backwardly directed preorbital process below. On the anterior side of the orbit is a very smooth, hollow surface, against which the eyeball rolls. On the cranial wall at the anterior end of the orbit is developed a rather prominent articular surface which receives the inner side of the ethmo- palatine process of the palatoquadrate cartilage. The supraorbital ridge is somewhat thin and prominent. In the shallow groove along its dorsal surface are a number of foramina which transmit branches of the ophthalmicus branch of the seventh nerve supplying the supraorbital sensory canal. Garman described the postorbital process ( P0.p. )as of irregular shape and moderate breadth. In the specimen which I ‘have examined it appears to be quite regular in outline. It is a back- wardly curved, stoutish process, gradually tapering towards its rounded end. On its upper surface are found a number of foramina which also transmit branches of the seventh nerve to the sensory canal-system. From the median vertical longitudinal section of the cranium (fig. 2), it is seen that the notochor ‘d is continued as a thin strand of tissue in the basis cranii as far forward as the pituitary fossa. ESL Os ANATOMY OF THE FRILLED SHARK. 543 The cartilage of the floor of the craniam in the region of its junction with the vertebral column is thick and somewhat heavily calcified. It here shows some indication of its probable vertebral nature, by the slight resemblance which the calcification presents to the inverted V-formation found in the centra of the vertebral column. The nerve foramina, as seen both from the inside and from the outside of the skull, deserve some consideration. The foramen for the first nerve (1.) is very large and lies just below the opening of the anterior fontanelle. The optic nerve foramen (II.) is moderately large and, seen from the inside, lies a short distance posterior to the opening for the olfactory nerve. On the outside it opens into a deep channel on the anterior dorsal side of the smooth articular surface which receives the ethmo-palatine process of the palatoquadrate. It is thus situated comparatively far forward in the orbit. The foramen for the third nerve (111.) lies at the end of a for- wardly curved groove on the inside of the skull. Externally it is placed close to the floor of the cranium just behind the posterior ridge of the above mentioned articular surface. The aperture for the fourth nerve (1y.) is small and lies well up in the orbit, almost vertically above (im.). Behind foramen mt. is the cartilaginous optic stalk (0.s.), against the expanded end of which the back of the eyeball rests. Immediately posterior to the origin of this stalk is a fairly large foramen which transmits the interorbital blood-sinus. On the inside of the skull, it is divided by means of a thin, outwardly directed cartilaginous bridge. The interorbital sinus passes posterior to this, whilst the cavity anterior to it forms the pituitary fossa. The foramen of the internal carotid artery (2.¢,f.) is a small aperture lying in the floor of the skull immediately anterior to the pituitary fossa. Nerves five, six, and seven are transmitted by a very large foramen (v. vi. & vit.) which is about twice as long as broad, and has a thin, backwardly directed ridge on its anterior edge. Following this is a double foramen (vi. & vir.) on the inside of the skull, which transmits the hyoidean branch of the seventh nerve and also nerve eight. The hyoidean part is the anterior smaller portion, which is continued directly outwards and opens externally just beneath the postorbital process. The foramen for nerve nine is small and is somewhat ventrally placed a short distance posterior to foramen vit. It is continued obliquely under the auditory capsule and opens externally at the back of the cranium in a very deep depression, overhung by the occipital ridges. The tenth foramen is moderately large and on the’ inside is situated in the median line. It opens externally at the back of the skull just above the aperture for the ninth nerve. There are four small foramina, somewhat ventrally placed, the first one lying immediately below foramen x. These are the foramina of the ; aie see spino-oceipital nerves, so-so’. 544 MR. T. GOODEY ON THE SKELETAL ear or b. Labial Cartilages. These were not found by Garman, buat Fiirbringer (6) has de- scribed and figured them, and my observations agree swell with his. On each side of the head there are three small, rod-like cartilages, two dorsal and one ventral to the mouth. The ventral one is the longest and meets the posterior dorsal one at the point of the angle of the mouth where both are united by ligament. The dorsal one of this pair is about two-thirds the length of the ventral one and is somewhat inwardly directed. The anterior dorsal one is distinct from those just described. It lies at the posterior end of a hgament which stretches beneath the orbit from the outer ridge of the preorbital process to a point beneath the postorbital process. It is very thin and at its anterior end is also inwardly directed. ce. Mirst and Second Visceral Arches, Ligaments and Muscles. The suspension of the jaws is hyostylic. At its proximal end the hyomandibular aiticulates with a rather deep concavity on the auditory capsule. As Garman has pointed out, this articulation does not take place with the whole of the head of the hyoman- dibular, the latter having an oblique disposition to the skull. Thus, only the knob on the posterior side is in contact with the skull, and between the projecting anterior knob and the concavity there is a thick pad of capsular ligament. Garman has also given an accurate description of the general shape and disposition of the ° hyomandibular. It is suspended in a backward and downward direction at an angle of about forty degrees from the skull by a strong ligament which has its origin on the ventro-lateral surface of the auditory capsule. The ligament is attached to this region for some considerable distance, and from here proceeds obliquely backward. It lies internal and ventral to the hyomandibular, to which it is attached on the inner side at about one-half the length of the cartilage from the skull. It is post-spivacular in position and corresponds with the inferior post-spiracular ligament found in the Common Dogfish, Seylliwm canicula, as described by Ridewood (27). ‘There is no pre-spivacular igament in Chlamy- doselachus, aud I agree with Garman in not finding a spiracular cartilage, though Fiirbringer (6) has described and figured as one a minute piece of cartilage which shows hyaline structure in microscopic sections. I have little to add to Garman’s account of the upper and lower jaws; my observations confirm their shape and disposition as recorded by hin. The joint between these two cartilages js a very interesting one, and was not dealt with in the original description. It is visible only when the jaws are opened to their widest extent (fig. 3). There are two articulations, each of the cup and ball type, one on the outer and one on the inner side of the jot. On the outer or posterior articulation the quadrate forms a broad, rather flattened knob which fits into a slight concavity of the 1910. ] ANATOMY OF THE FRILLED SHARK. DAD posterior and outer end of the mandible. The inner or anterior articulation is formed by a prominent rounded protuberance— somewhat more than half the width of the one on the quadrate— which projects upwards into a corresponding concavity or facet in the quadrate. This joint affords a resemblance with Heptanchus, the corre- sponding joint in which has been worked out by Gadow (8). There is the difference, however, that in Chlamydoselachus it is much more pronounced and has not the space separating the two articulations found in Heptanchus. Garman mentions a palatal or trabecular process which occurs at a point an inch and three-quarters behind the front end of the palatoquadrate, and is received in a concave articular depression of the skull in the orbit. He says that it is attached at its upper end by ligament to the skull near the top of the orbital cavity. I have found the process in question in both skulls that I have examined. It is perhaps better to call it an ethmo-palatine process, this being in accord with modern nomenclature. I cannot, however, agree with Garman in what he says about its ligamentous attachment to the skull. It is not attached by any definite band-like ligament such as that figured by him on PI. viii. It is surmounted by a pad of capsular ligament which appears to be in the nature of a thickening of the general soft connective tissue surrounding the whole process. A similar capsular ligament has already been described as occurring between the obliquely placed head of the hyomandibular and the articular concavity on the side of the _ auditory capsule. Both are very different from the strong, fibrous, band-like post-spiracular ligament which suspends the jaws from the skull. I have found the hyal process which occurs on the upper ridge of the quadratic portion of the upper jaw, close to its posterior end, overhung by a similar one on the hyomandibular. The larger quadratic or otic process however, which, according to Garman, occurs farther forward at the widest part of the palato- quadrate, I have failed to discover. The ceratohyals articulate by the anterior lobe of their lower extremities with the ventral surface of the basihyal, on either side of the median line. The latter cartilage is situated well forward between the mandibles and is raised up slightly into the oral cavity. As Garman has pointed out, it is elongate and tapers from the broader posterior end to the rounded anterior end. In the middle of the concave posterior border is a small, backwardly directed prominence, which Fiirbringer (6) considers as the repre- sentative of the copula or basibranchial of the first branchial arch. The two lateral prominences, also at the posterior end, no doubt represent the hypobranchials of the first branchial arch as Garman suggested, and these together with the basibranchial have lost their distinct nature by becoming fused into the general mass of the basihyal. On the ventral surface of the basihyal is found the somewhat Proc. Zoou. Soc.—1910, No. XXXV. 35 546 MR. T. GOODEY ON THE SKELETAL [ Mar, 15, oval excavation mentioned by Garman. In two cases out of three which I have examined, this communicates with the dorsal surface of the basihyal by means of a small round aperture at the anterior end of the concayity. In the third case, the excavation is not covered above by cartilage but was found to open directly into a slightly smaller concavity on the dorsal surface of the cartilage. The thyroid gland is situated in the hollow excavation on the ventral side, and in one example examined, a very in- teresting tubular structure, attached to the gland and communi- cating with the oral cavity, has been discovered. This is dealt with in a separate paper *. A strong ensheathing fibrous ligament wraps the inner side of the quadrato-mandibular joint. It is continued on to the outer side of the joint and then proceeds backward to wrap the distal end of the hyomandibular and the proximal end of the ceratohyal, both of which are somewhat closely applied to the jaw joint (fig. 4). It is by this ligament that the hyostylic suspension of the jaws is is brought about. The ceratohyal is very closely applied in the greater part of its length to the inner side of the mandible where it fits into a sort of shallow groove. It is held firmly in its position by means of two important ligaments, in addition to the one just described which connects its proximal end with the angle of the jaws. Of these two ligaments one is external and the other internal in position. The former stretches between a process on the outer ridge of the ventro-posterior side of the mandible and a corresponding ridge on the outer edge of the ceratohyal. It is about half an inch in width, and may be termed the ligamentum hyoideo-mandibulare externwm. The inner one is a broad, flat ligament (fig. 5) attached at its upper end to the convex inner surface of the proximal end of the palatoquadrate cartilage, and, stretching across the jaw joint andthe mandible, is inserted along the ridge on the inner and upper side of the ceratohyal. It may be termed the ligamentum quadrato-hyoideo anternwm. The disposition of the head muscles has been dealt with by Furbringer (6), but the more important ridges and processes on the skull and jaws, which serve for the attachment of these muscles, are also worthy of some attention, seeing that they are quite pronouncedly developed. It will perhaps be easier in dealing with these to take the muscles separately and describe their relations to the particular ridges of attachment. Levator maxille is attached above to the thin ridge (s.e.s.) (é. in Garman, Pl. vii. fig. A) which projects over the auditory capsule, and to the posterior edge of the postorbital process. It extends in front of the spiracle and is inserted on the inner and upper edge of the prominent ridge (pq.r.) along the dorsal side of the quadratic portion of the palatoquadrate. This in- sertion extends as far backward as the hyal process. * Goodey, T., “ Vestiges of the Thyroid in Chlamydoselachus anguineus, Seyllium catulus and S. canicula.” Anatomischer Anzeiger, Bd. xxxvi. 1910. 1910. ] ANATOMY OF THE FRILLED SHARK. 547 Adductor mandibule is a thick massive muscle, filling up the concavities on the outer sides of the palatoquadrate and the mandible. It is divided by an aponeurosis, which is in the line of the mouth angle, and is attached above to the lower edge of the palatoquadrate ridge previously mentioned. Below, it is similarly attached to a correspondingly sharp ridge (m.7.) on the ventro-lateral border of the mandible. Constrictor superficialis is a thin, extensive muscle lying behind the hyomandibular. It extends round the jaw angle to the ventral surface of the head, where it lies between the mandibles. It is attached above to the posterior end of the supra-capsular ridge (s.c.r.) and also to the outer surface of the hyomandibular, On the lower side it is attached to the inner edge of the sharp ridge (m.r.) which extends along the ventro-lateral border of the mandible. d. Branchial Arches (Plate XIII. fig. 6). Basibranchials—The basibranchial of the first branchial arch is, aS previously mentioned, probably represented by the median prominence (ddr. 1) on the posterior border of the basihyal. The second one (6b. 2) is situated considerably posterior to the first, level, in fact, with the bases of the third ceratobranchials. It is triangular in outline, attached anteriorly to the second pair of hypobranchials (Abr. 2) and is free behind. The third (ddr. 3) is also triangular in outline and is distinct. It is attached by ligament anteriorly to the third pair of hypobranchials and is firmly united behind by ligament to the fourth pair of hypo- branchials. The fourth basibranchial is indistinguishable from the corres- ponding hypobranchials. Garman describes it as lying between these. However, in the two cases that I have examined it is certainly not present, and I am inclined to believe that it has become fused with the large posterior basibranchial. The latter no doubt represents the fourth, fifth, and sixth basibranchials together with their corresponding hypobranchials all fused into one piece. It ends posteriorly in an elongate, tapering median process. Hypobranchials.—The pair corresponding to the first arch are represented by the lateral prominences (br. 1) on the posterior border of the basihyal. The second pair (Abr. 2) are flat and broad anteriorly, where they overlie the expanded part of the lower ends of the first ceratobranchials. They are somewhat thin there, and on the posterior edge are united by hgament to their corresponding ceratobranchials. ‘Towards their posterior extremities they gradually taper and they are united to the second basibranchial. The third pair (Abr. 3) is essentially similar in shape to the second pair, the articulations being with the corresponding ceratobranchials and basibranchial. The fourth pair (Abr. 4) is more rounded than the second and third, and each hypobranchial has a bend in it so that the lateral part Stale out 30 548 MR. T. GOODEY ON THE SKELETAL | Mar. 15, at right angles to the axial portion. The cartilages forming this pair are fused in the median line, and are closely united by liga- ment with the large posterior basibranchial. In another example they are not fused with each other, but are closely and firmly attached together by ligament (fig. 6). The fifth pair is repre- sented by rather prominent lateral processes (Abr. 5) which le close to the anterior end of the large basibranchial. The sixth pair is also represented by lateral processes, not so pronounced, however, as the fifth pair. Ceratobranchials.—I have little to add here to Garman’s description, except to say that all—excluding the sixth—have a forward bend at their lower extremities, which brings these parts parallel with the median horizontal axis. The first and second pairs are curiously expanded also in this region, having an almos bilobate appearance. The posterior part of the expansion is rounded and underlies the expanded part of the following hypo- branchials. The sixth pair is very massive and on its anterior ventral border each has a thin, almost wing-like portion, which Furbringer considers as the representative of the branchial rays of this arch. There is nothing of note in the epi- and pharyngo-branchials of the first five arches. In the case of the sixth, however, it is probable that only the epibranchial is present; the pharyngo- branchial being perhaps incorporated with it. It has a peculiar shape, quite different from the slender, tapering bar figured by Garman. At its point of attachment to the distal end of the ceratobranchial it has an irregular outline. It next narrows somewhat, and then carries a small process on its inner concave border. The outer edge is convex and the whole piece gradually tapers to a rounded end, which is anteriorly and inwardly directed. Seventh vestigial arch.—This is not present in the specimen which serves for the description of most of this paper, unless it be that it is represented by a pair of rather sharp ridges on the ventral side of the last basibranchial at the proximal ends of the sixth ceratobranchials. In the case, however, of the large female specimen it is present, and takes the form of a pair of small seg- mental, tapering pieces (v.b.a. 7) lying on the ventral side of the last basibranchial at the bases of the sixth ceratobranchials. Each arch consists of two small pieces of cartilage united by connective tissue fibres to the surrounding parts. The more anterior portion in each is rather irregular in outline and on its posterior border carries a second slender, tapering portion. Fiirbringer (6), who was the first to describe this very interesting vestige, merely speaks of it as a small piece of cartilage, and his figure gives no adequate idea of its structure and disposition relative to the surrounding parts. As amatter of fact, it is very variable in structure; for that described by Hawkes (17) was made up of four small pieces on 1910.] ANATOMY OF THE FRILLED SHARK. 549 one side and two on the other, lying close to the ceratobranchial of the sixth arch on the posterior side near to the median extremity. e. Branchial Rays. These are thin, tapering rods of cartilage lying embedded in the interbranchial septa, a little closer to the inner surfaces of the latter than to the outer. Proximally they are applied to the posterior sides of the branchial arches, and distally they project somewhat beyond the margins of the interbranchial septa, to which they thus give a crenulate appearance. One or two cases were observed in which two rays appeared to be fused proximally, apparently having a common origin. In another case two rays which had separate origins fused, and became produced so as to form one ray. The greatest number of rays occurs on the hyoid arch, and as we proceed posteriorly the number gradually decreases for the six branchial arches, though subject to some variation. The sixth arch carries no distinct rod-like rays, but a thin laminate portion (i.p.) is found on the anterior ventral edge of the ceratobranchial. This, as previously mentioned, is regarded by Firbringer as the representative of the branchial rays fused with the ceratobranchial. Whether this is the case or not, appears to me to be an open question. This lamina may be merely a thin extension of the ceratobranchial. Again, there seems to be no particular reason why the original branchial rays—if such were present—should have fused into a common lamina and have become firmly attached to the arch. As a rule, it appears, branchial rays are not met with on the last arch in Selachians, and why this portion should be looked upon as their representative in Chlamydoselachus it is somewhat difficult to understand.

The external opening of the left spiracle is an obliquely placed slit on the postero-dorso-lateral surface of the head, measuring about one centimetre in length. The right one is about one-half this length. On removing the skin and carefully dissecting away the underlying spongy cutis which covers the jaw-muscles, it is seen that the lumen of the spiracle passes down into the oral cavity between the hyomandibular and the mandibular cartilages. Just inside the external opening, the cavity becomes enlarged and a short cecal diverticulum is given off anteriorly. This is overlaid by the levator mawille muscle whose disposition has already been described. The cecum extends as far forward as the anterior knob of the proximal end of the hyomandibular, which projects from the articular depression on the auditory capsule. It is not attached to the hyomandibular, but is separated from it by the hyoidean branch of the seventh nerve, which passes just internal and ventral to it. In all probability it is homologous with the more extensive ceca mentioned by Ridewood (27), which have been described in other Selachians by Miiller and Van Bemmelen. In Seyllium, for example, the cecum extends inwards over the hyomandibular and becomes firmly attached to the wall of the auditory capsule, being in some way concerned with the function of hearing. A similar cecum is found in Heptanchus, so that here we have another point in which Chlamydoselachus differs from this member of the Notidanide. The pseudobranch in each splracle consists of about ten short ridges, which lie on the anterior outer wall just inside the external aperture. In the Notidanide the pseudobranchs are said to be better developed than in any of the Selachians, so that in this respect we find Chlamydoselachus presenting a small difference from Heaanchus and Heptanchus. g. Keatures of Specialization and Comparison with Notidanide. Perhaps the most important point in regard to the specialization of the skull of Chlamydoselachus is to be seen in the extreme Jength and mobility of the jaws. These are exceptionally long, extending from the anterior, almost terminal mouth to a point well behind the posterior limit of the cranium. This extension is remarkable ; in fact, one quarter of the total length of the jaws is found in this region, and it is this feature, connected with the exceptional length of the hyomandibular, which gives the jaws their great mobility. Indeed, their disposition relative to the cranium is quite different from that found in any other Selachian whose skull [ have been able to examine or to see a figure of. It resembles nothing among the Vertebrates so much, perhaps, as. the general disposition of the jaws in certain of the Ophidia. In this respect also Chlamydoselachus presents a striking difference from the two genera of the Notidanide. In both Hewxanchus and Heptanchus the mouth is ventral and is situated far back. The 1910. ] ANATOMY OF THE FRILLED SHARK. Dol suspension of the jaws is amphistylic, and the palatoquadrate cartilages have a postorbital articulation with the craninm. Moreover, the extension of the jaws posterior to the cranium is but very slight. IV. Tue Mempranous Lasyrinte. (Plate XLII. figs. 7 & 8.) The organ of the right side of the head has been worked out by dissecting away the surrounding cartilage, and forms the basis of the following account, On removing the skin from the dorsal surface of the cranium it is seen that the pavietal fossa is rather deep and possesses four apertures, two on either side of the median longitudinal line. One of these apertures, the anterior, is small, pat transmits the ductus endolymphaticus. The posterior is larger and is closed with soft subcutaneous tissue. It is an opening into the peri- lymph cavity surrounding the posterior vertical canal, and seems to correspond to the tympanic aperture which Howes (19) described in Raia. Before proceeding further, 1 may mention that in this account I am following the nomenclature used by Stewart (30), which differs somewhat from that used by Retzaius (26) in his great monograph. The duties endol: ymphaticus, on emerging from its cranial foramen, soon expands into the saccus endolymphaticus. ‘The latter lies partly in the parietal fossa and is partly attached to the under surface of the skin covering this region. It is fairly regular in shape, somewhat rounded on its anterior surface, and extends posteriorly in a slightly outward direction, gradually becoming attenuated until it reaches its external aperture, which is quite small, Internally the ductus endolymphaticus leads into the sacculus. This is not rounded, but is laterally flattened, and gives off at its postero-inferior end the lagena in the form of a simple cecum. The wtriculus in this species is like that in other Elasmo- branchs, being divided into two portions, anterior and posterior’, which do not communicate directly with each other, but in- directly through the sacculus. The anterior utricle is rather laterally compressed and gives off the anterior canal dorsally. The latter curves forward and slightly outward, and deseribes almost a semicircle in its course, expanding at its lower end into the anterior ampulla, which then opens by a wide portion into the lower end of the utricle again. The recessus utriculi is a somewhat spherical structure on the inferior and outer border of the anterior utricle. It communi- cates with the latter by means of a slit-like aperture just below that leading into the ampulla externus. Vhe anterior utricle does not open directiy into the sacculus, but communicates in- directly with it through the recessus utriculi, which opens into the sacculus by means of a rounded aperture on the postero- dorsal side of the recessus. 052 MR. T. GOODEY ON THE SKELETAL { Mar. 15, Arising from the dorsal end of the anterior utricle, and pro- ceeding in a posterior and outward direction, is the eaternal canal, which bends downward and comes to lie in an almost horizontal position. At its anterior end it is slightly elevated and expands into the ampulla externus, which communicates with the anterior utricle again by means of a short canal which rests on the upper side of the recessus utriculi, but does not open directly into it. The posterior utricle, which is situated more internally than the rest of the labyrinth, is somewhat cylindrical in shape and is slightly curved upon itself. It communicates directly with the sacculus by means of a short, almost vertical canal, the ductus utriculo succularis posterior. Arising from its dorsal end is the posterior canal, which curves outward and downward, and then expands into the posterior ampulla, which opens into the lower end of the utricle again. All three canals, anterior and posterior vertical and external horizontal, are not rounded in section, but are markedly flattened, so that their height is equal to about twice their width. The external canal in its almost horizontal position lies with its compressed sides in the horizontal plane. Nerve-Supply. The sensory areas of the membranous labyrinth are supplied by branches of the eighth cranial nerve. After passing from the brain through its foramen, the nerve breaks up into a number of ramuli which supply their particular regions. The ramulus ampulla anterior is a rather fine branch which extends from the main nerve-trunk to the anterior ampulla, lying chiefly on the outer side of the lower portion of the anterior utricle. Arising next from the main trunk are two ramuli, which appear to have a common origin. These are the ramulus recessus utriculi and the ramulus ampulla externus. Both curve under the recessus utriculi and come to lie on its outer surface, the ramulus ampulla externus proceeding upward on to the external ampulla, where it supplies the two rounded criste. The main portion of the nerve now goes on to form the ramuli sacculi. It first gives rise to a flattened branch which extends upward and follows the inner anterior border of the sacculus, thus forming one ramulus sacculus. The rest of the nerve proceeds in an almost horizontal direction and lies on the inner surface of the sacculus, forming the main ramulus sacculus. This gives off fine branches on its lower side which supply the macule of the sacculus. Arising from its posterior end are three fine branches: a lower one, the ramulus lagena, supplying the macule of the lagena; a median one, the ramulus ampulla posterior, lying chiefly on the inner surface of the posterior utricle and supplying the : 1910.3 ANATOMY OF THE FRILLED SHARK. 553 J posterior ampulla; and an upper one, the ramulus neglectus, which curves upward toward the ductus utriculo saccularis posterior. In structure and in the distribution of the nerve-supply the membranous labyrinth of Chlamydoselachus resembles rather closely that of Votidanus (Hexanchus) griseus figured by Stewart (30). V. VERTEBRAL Cotumn. (Plates XLITI.—XLV. figs. 9-17.) The notochord is persistent, and reaches from the pituitary fossa in the basis cranii to the extreme tip of the long tapering tail. There is an elastic supradorsal longitudinal hgament which extends from the back of the cranium to a point just posterior to the dorsal fin, where the dorsal supports of the caudal fin commence. The number of vertebre, as determined by neuromeres, is one hundred and twelve, and this number includes the irregular region at the extreme tip of the tail—to be dealt with in detail later. In determining this number, I have counted the ventral root foramina of the spinal nerves carried by the basidorsals, as these are larger than the dorsal root foramina. : Moreover, the first foramen at the anterior end of the column is a ventral one. The vertebral elements present, named according to Gadow’s (9) nomenclature, are as follows :— Dorsalia: basidorsals, interdorsals, and suprabasidorsals, the last-mentioned being segmented off from the apices of the basi- dorsals. The dorsal radial supports of the caudal fin I do not consider as dorso-spinalia, because at their commencement an- teriorly they are not always continuous with the neural arches, and, moreover, there is as much evidence to show that in general they originate independently of the vertebral column as there is in favour of their being portions segmented off from the dorsalia below them. Ventralia: basiventrals, interventrals, ribs, and hemal arches, and heemal spines in the caudal region. I have been unable to find the calcifications which Garman mentions as occurring in the mouths of the foramina for the spinal nerves. No trace of them can be detected even after carefully cleaning away the connective tissue which closely invests the vertebral column. In fact, it would be somewhat surprising if such calcifications were present, considering the small amount of calcareous secretion found in the skeleton at all. It is perhaps worthy of note that, in the largest specimen examined, the vertebral column over the abdomen was not straight, but was contorted so as to have an undulating outline in the horizontal plane. Whether this was due to abnormal growth or to the action of the preservative I do not know, but I am inclined to the latter view. In connection with the formation of centra, my investigations have revealed a number of points which Garman did not observe, 554 MR. T. GOODEY ON THE SKELETAL [ Mar. 15, and for this reason my account will be somewhat full. For purposes os description I have divided the column into four regions, 1, 2,3, and 4, which are quite arbitrary, and, though not cnumigeporaing exactly with any recognized divisions of the body, yet may roughly be described as cephalic, trunk, main caudal and terminal caudal regions. My reason for doing so is, that to treat of the whole length of the column in a continuous deserip- tion would mean a needless repetition of words, thus tending to make the meaning obscure. The regions are as follows :— 1. Anterior cephalic portion extending for about twelve centi- metres behind the skull. 2. The region extending from the posterior end of 1, over the abdomen and reaching to the level of the cloaca ; what may conveniently be termed the “trunk region.” 3. The main caudal region extending from the posterior end of 2 to a point about eleven centimetres from the tip of the tail. 4. The last eleven centimetres of the tail, terminal caudal region. h. Description of Regions 1, 2, 3, and 4. The vertebral column is fused to the cranium quite firmly, so that but slight articulation 1s possible between the two. In this particular region of the column, viz. 1, there are regular vertebral constrictions of the notochord in the form of ring-like thickenings of the chordal sheath (fig. 9). This figure represents a view of a median, vertical, longitudinal section. It can be easily made out from this that each constriction occurs beneath a basidorsal, and also that the majority of the constrictions are well calcified. This particular point is of considerable interest, and is here fully dealt with. The first five constrictions—counting from the left— are calcified regularly, so that each centrum is typically cyclo- spondylic, being in the form of a short cylinder pinched in round the middle. The calcified areas thus present the appearance of two V’s placed point to point. The sixth centrum has a calcified V above, but below, the calcification is irregular, being repre- sented by only a small patch of calcareous secretion. The seventh is regular above, but below, the V is calcified all over. Hight, nine, and ten are also regular above and below, except that the lower V is larger in each case than the upper one, the latter in the tenth being very small. Constrictions are visible beneath basidorsals eleven, twelve, and thirteen, but no caleified areas are apparent in these cases, although, externally, the notochord shows definite calcified bands in the case of eleven and twelve. With these two, then, it is evident that calcification has not proceeded as far inward as in the more anterior ones. It also reveals the fact that the process of the deposition of calcareous salts begins on the outside of each constriction, and gradually proceeds towards the interior. Constrictions eleven and twelve may be looked upon, therefore, as being in a state of semi-calcification, whilst thirteen is merely a constriction of the chordal sheath, in which calcification has not commenced. ‘The intervertebral 1910.] | ANATOMY OF THE FRILLED SHARK. 509 Spaces are filled with soft notochordal tissue, and there are no secondary calcifications in these areas. For comparative purposes I have thought it worth while to give a drawing (fig. 10) of a corresponding anterior region from another and larger specimen. In this there are seen eleven definitely calcified cyclospondylic centra, which gradually increase in width as we proceed from left to right. Each one is in the form of two V’s placed point to point, and, moreover, corresponds exactly in position with a calcified band on the exterior of the notochord. It is worthy of note also that the soft notochordal tissue gradually becomes obliterated from the intervertebral spaces as we approach the skull, so that in the space between the first centrum and the cranium soft tissue is not present at all. The larger, more definite, and regular calcifications of the centra in the larger specimen are of considerable interest because they seem to indicate—as will be shown in another region of the vertebral column—that the extent to which calcification takes place depends upon the age of the specimen, for apparently the size depends upon the age. The older the specimen the more definitely and regularly calcified are the regions where calcifica- tion may occur. Garman mentions this region, and says that there are vertebral constrictions which are somewhat calcified, but he does not state how far this condition obtains, and his figure of a longitudinal vertical section taken in this region is very indefinite. The calcified areas are represented as being of irregular shape, much more rounded than those which I have found. They are also continuous with one another, whereas those which I have found are quite discontinuous. Region 2.—The “trunk region” is the longest of all, and shows the least differentiation of the notochord. The dorsalia are represented by basidorsals and interdorsals, triangular in outline, suprabasidorsals segmented off from the apices of the basidorsals as small wedge-shaped pieces. The ventralia are represented by basiventrals, somewhat rectangular in outline, and rounded interventrals. The latter are comparatively small, and gradually decrease in size as we proceed posteriorly. The notochord is of uniform diameter, and shows slight but unmistakable signs of segmentation ; each segment corresponding exactly with a basi- dorsal above and a basiventral below. The segmentation is shown by a difference in the appearance of the chordal sheath along lines corresponding in position to the ends of the basi- dorsals. At these points there appear to be narrow rings or annulations of the notochord as shown in fig. 11. In a view of the cut surface of a vertical longitudinal section of a portion from this region, no apparent constrictions of the notochord are found to correspond with the external segmentation of the chordal sheath. The interior of the chord presents a fairly uniform appearance, as was noted by Garman. If, however, a horizontal longitudinal section be made of the notochord, a regular sequence of constrictions of the chordal sheath is at once 006 MR. T. GOODEY ON THE SKELETAL [ Mar. 15, apparent. Hach of these occurs beneath a basidorsal, and extends between two consecutive segmentation marks on the exterior of the chordal sheath. Hach takes the form of a bulging inward of the sheath, so that a slightly pinched-in cylinder is formed. The regions described thus far are typically monospondylic, ¢.e. each neuromere is made up of one of each of the vertebral elements, one basidorsal, one interdorsal, one suprabasidorsal, one basiventral, and one interventral The foramina for the spinal nerves do not occur between the dorsalia, but are actual perforations of the basidorsals and interdorsals. In the mono- spondylic regions each basidorsal transmits a foramen for a ventral root and each interdorsal one fora dorsal root. The ventral root foramina are larger than the dorsal ones. Ribs. These are small, thin, cartilaginous pieces segmented off from the basiventrals, with which they are continuous. They occur in regions | and 2, and extend from the eighth to the sixty- fourth neuromeres inclusive. At their posterior end they reach a point on the vertebral column a short distance anterior to the level of the cloaca, where they terminate abruptly, having apparently diminished but very little in size. More pcsterior to this point the basiventrals begin to grow downward, and gradually assume the form of wedge-shaped pieces which afterwards fuse beneath the hemal canal and thus give rise to the hemal spines. Region 3.—At the seventieth neuromere we get the transition from the monospondyle to the diplospondylic condition taking place (see fig. 12). As represented in the figure, the latter con- dition appears to be brought about by the segmenting off of a small basidorsal from the anterior side of a typical monospondylous one. By this means each single large basidorsal gives rise to two smaller ones, and between these there is inserted a small inter- dorsal. The small basidorsals have narrow suprabasidorsals seg- mented off from their apices as thin wedge-shaped pieces. A ventral root foramen perforates the posterior one of each pair of diplospondylous basidorsals, whilst the succeeding interdorsal transmits a dorsal root foramen. In this way we have the typical diplospondylic condition of vertebrae brought about, and this arrangement obtains to a point about eleven centimetres from the tip of the tail. At the seventy-second neuromere, as shown in fig. 12, we find the monospondylic condition again occurring, apparently as a reversion to the more primitive stage in development. Instead of finding two of each of the arcualia we only havea single large basidorsal with a ventral root foramen near its posterior edge, followed by a single large interdorsal. However, on the lower side of the notochord there are two basi- ventrals and interventrals, thus indicating that although the dorsalia have not been segmented into the double condition, yet this has occurred in the ventralia. This single neuromere is of interest, because it seems to indicate that the diplospondylic con- dition is the secondary one, arising by segmentation of the parts which go to form the more primitive monospondylic condition. . ~ eed ees eee eee 1910.] ANATOMY OF THE FRILLED SHARK. DOT Tt can be seen from fig. 13 that in this diplospondylic region we have an alternation of imperforate and perforate basidorsals, between which occur the perforate and imperforate interdorsals. On the ventral side of the notochord we have a similar segmen- tation of the ventralia. The notochord in this region has a segmented appearance, which is brought about by the occurrence of bands of cartilage round it. These bands are in reality extensions of the dorsal and ventral arcualia—basidorsals and basiventrals—round the chordal sheath, and they alternate regularly with spaces in which the sheath is naked. They are found in the trunk region as well, only there each cartilaginous band is very thin, and is only recognizable in microscopic sections. In the main caudal region, however, the bands are much more pronounced in growth. Here also there is a marked difference in the relative size of the two kinds of basidorsals. The imper- forate ones are larger than the perforate, and this difference in size obtains especially where the caudal fin is deepest. As we proceed towards the tip of the tail the dorsalia gradually become more nearly equal in size until at a point just anterior to where they lose their identity, they are quite equal. Perhaps the most interesting feature, however, of the skeleton in this particular region is that which is found from a point level with the posterior end of the anal fin to within a short distance of the tip of the tail. Here we find definite calcified rings round the chordal sheath which correspond in position to the basidorsals above and lie internal to the cartilaginous bands just mentioned. They are shown in fig. 13, where they appear as unshaded bands on the notochord extending between a large imperforate basi- dorsal above and the corresponding basiventral below. There is also an indication in the figure of a band beneath a perforate basidorsal and this, as it stands, may be somewhat misleading, appearing as if it were somewhat exceptional. This, however, is not the case, as only a short distance posterior to the portion figured the calcified rings become as well marked beneath the perforate basidorsals as beneath the imperforate ones. Fig. 14 represents a longitudinal vertical section of fig. 13. It is at ‘once apparent from this that internal to each broad calcified band, 7. ¢. beneath each imperforate basidorsal, we have a con- striction of the chordal sheath in the form of an incipient centrum, the calcification extending into it and lending it additional strength. Beneath each perforate basidorsal also there is a very slight constriction of the chordal sheath without any trace of calcification. The points just dealt with are shown much more clearly in a portion of the vertebral column taken from the larger, and probably older, female specimen. In this the extensions of the arcualia are very pronouncedly developed in the main caudal region, those beneath the perforate basidorsals being quite well shown. Both the latter and the larger ones beneath imperforate basidorsals are ridged in surface view as shown in fig. 15 In a 098 MR. T. GOODEY ON THE SKELETAL [Mar. 15, or view of a longitudinal vertical section of this portion (fig. 16), it is at once evident that in this specimen the formation of centira has proceeded much farther than in the smaller and, doubtless, younger specimen. The constrictions beneath the imperforate basidorsals extend well towards the centre of the notochord, whilst those beneath the perforate basidorsals are quite well developed, being much larger and more sharply defined than the corresponding constrictions in the smaller specimen. In both large and small constrictions also calcification has taken place, so that rounded V’s are shown in the sectional view. In the caudal region, then, we have well-marked, incipient, eyclospondylic centra. Another point which is especially imter- esting is that the calcified rings become most strongly developed in that part of the notochord below which the ventral lobe of the caudal fin has its greatest depth. One would expect this to be the case when the occurrence of centra and calcified bands is considered from the point of view of the mechanical importance of this region. If the diplospondylic condition of the vertebral column is concerned, as Ridewood (28) suggests, with flexibility, then we have here double the number of parts capable of articu- lation with one another that we should have if the monospon- dylic condition obtained in its place. Since also, the greatest purchase on the water is obtained by the tail where the caudal tin 1s deepest, we should expect to find here not only flexibility provided for but also a provision for increased strength in the skeletal supporting tissue. This is indeed what we actually find, for, as poimted out above, the diplospondylic condition is found here and the incipient centra are most strongly developed and calcified over the deepest part of the caudal fin. Region 4.—This short region is of particular interest, because it has not been figured and described before. The specimen which Garman figured had lost the extreme tip of the tail. Fig. 17 represents it natural size, and from this it is seen that the vertebral column is a gradually tapering structure which remains segmented up to the end, no urostyle being present. The noto- chord has but very slight growths of the arcualia round it, and in two parts it is shghtly segmented externally. In the dorsalia at the commencement of the region can be recognized both basi- dorsals and interdorsals. Very soon, however, the distinction between them becomes lost and they apparently fuse with each other to form small, irregularly shaped pieces, which, towards the extreme tip, are rhomboidal in outline and are of varying lengths. The dorsal radial elements, which are borne on the dorsal side of the neural arches, are also of variable length. They do not corre- spond segmentally with the dorsalia, and as we approach the extreme tip of the tail they become comparatively long. The hemal spines are the most regular in shape and occurrence, being, with one or two exceptions, of the same width up to the end of the tail. The point of special interest in ati region is the disposition = = t er Ne 1910. ] ANATOMY OF THE FRILLED SHARK. 599 of the nerve foramina, which perforate the dorsalia. Anterior to the portion figured, the caudal region is typically diplospondylie, as already described. The ventral foramina are, throughout the vertebral column, larger than the dorsal ones. At the com- mencement of the figure, on the left-hand side can be seen a basidorsal which carries a nerve foramen. The succeeding inter- dorsal is imperforate, the dorsal and ventral roots of the spinal nerve having apparently united or approximated very closely together so fee one foramen will transmit both. This condition also holds for the succeeding spinal nerves. In counting the number of dorsal elements separating the foramina depicted in fig. 15, it is seen that between the first foramen and the following one there are two dorsal elements. Between the second and third there are also two; between third and fourth, three; between fourth and fifth, nine; between fifth and sixth, eleven; and between this and the end of the tail there are thirty elements without a single perforation. This arrangement of the foramina in relation to the number of dorsalia is obviously quite irregular, and so far from being in accord with Ridewood’s (28) and Mayer’s (22) contention that “the terminal region of the vertebral column is monospondylic, it shows that in Chlamydoselachus, at any rate, the neural apertures are so irregular in arrangement that this particular region may quite well be termed ‘heterospondylic.’ The musculature of the region in question is very much reduced, and we should scarcely expect to find so perfect a nerve-supply as is found more anteriorly. Moreover, with the irregularity in the shape and size of the arcualia and their non- -segmental arrange- ment relatively to one another, it is difficult to imagine How a monospondylic condition could obtain here. It seemed desirable to ascertain in what relation the myomeres of the tail stand to the neuromeres. In order to do this She skin was taken off from the other side of the tail and posterior portion of the trunk, so as to reveal the myomeres with their separating myocommata, On examining the limits of the mnyomeres it was seen that each one in the trunk corresponds 1 mm extent with a monospondylic neuromere. In the main caudal region each myomere is equal in extent with a diplospondylic neuromere. A determination was next made of the number of myomeres from the beginning of the diplospondylic region to the point where the distinction between the separate myocommata 1s lost, @. e. within five centimetres of the extreme tip of the tail. This number is forty-two. The number of neuromeres was next determined for the same region, and this also is forty-two. Thus the number of myomeres and neuromeres is the same in the tail, and each irregular or heterospondylic neuromere of region “4” has its corresponding myomere. The number of neuromeres for the side of the tail on which the myomeres were counted was next determined. After care- fully removing the muscular tissue, the spinal nerves were left, and by examining these through a dissecting microscope their 560 MR. T. GOODEY ON THE SKELETAL [ Mar. 15, number and distribution could be determined. The relation of their foramina to the dorsalia presents a considerable difference from the condition found on the other side of the tail. The total number of neuromeres for the region in question is the same for both sides, viz. forty-two; but instead of the irregularly-disposed foramina being separated by dorsal elements arranged in the order of the numbers, 2, 2, 3, 9, and 11, we find the following numbers of dorsalia separating them, 1, 2, 2, 2, and 14. From this it can be seen that the regular diplospondylic condition has proceeded one neuromere more posterior on this side than on the other, and that the following three are also more regular than the corre- sponding three of the other side. But there is no indication of a return to the monospondylic condition. This very interesting condition of heterospondyly is one which, so far as I have been able to ascertain, has not been described for any other Selachian fish. i. Summary of special features and comparison with Notidanide. In summarizing the leading characteristics of the vertebral column of Chlamydoselachus, the following points may be men- tioned :—First, the variety which it exhibits in the formation of centra. At the extreme anterior end the constrictions form eyclospondylic well-calcified centra. These may be followed by. smaller constrictions in a semi-calcified condition. In the trunk- region are found the slightly constricted cylinders of the noto- chord, representing the lowest of all the stages in centra-formation. The main caudal region is characterized by the. occurrence in it of constrictions of two sizes, the larger more calcified ones lying beneath the imperforate basidorsals, and the smaller less calcified ones lying beneath the perforate basidorsals. This difference in size gradually becomes lost as we proceed towards the tip of the tail, the constrictions becoming equal in size concurrently with the equalization in the size of the imperforate and perforate basidorsals. This particular point of the occurrence of centra in the tail-region is deserving of special emphasis, masmuch as three recent text-books of zoology give the uniform character of the notochord and absence of centra in this region as a diag- nostic feature of the Chlamydoselachide. The very pronounced growth of the basidorsals and basiventrals around the chordal sheath in the main caudal region is also very noteworthy. The great length of the diplospondylic region is of considerable interest, extending as. it does through thirty-eight neuromeres, viz., from seventy to one-hundred and eight. The heterospondylic portion of the tip of the tail is, so far as I am aware, unique in Selachians. The points at which the calcified centra occur is perhaps deserving of some mention. It seems that they are found where there are the greatest demands made for strength. At the anterior end, combined with the fusion of the vertebral column 1910.] ANATOMY OF THE FRILLED SHARK. 561 to the cranium, they give a rigidity to the supporting elements which is of service no doubt in enabling the fish to cleave the water. In the caudal region they meet the demand for increased strength caused by the purchase which the caudal. fin obtains upon the water. Compared with Hexanchus the vertebral column of Chlamydo- seluchus must be regarded, I think, as showing more specialized characters. In the former the notochord is simply constricted by annular thickenings of the cartilaginous sheath, no calcifications being present. The vertebral column of Heptanchus, however, is on the whole more specialized than that of Chlamydoselachus. for although the double-cone arrangement is not so pronounced at the anterior end as in Chlamydoselachus, yet the notochord is constricted vertebrally by a series of calcified rings which assume more and more the form of double cones towards the tail, And, moreover, in the caudal region secondary calcifications may give rise to a number of short rays radiating out from the centre of the double cones. VI. Precrorat GirDLE AND Fins. (Plate XLV. fig. 18.) Pectoral girdle.—I have nothing to add to the account of the girdle given by Garman (10. pp. 13, 14), except to say that my observations, made on three girdles, agree with his description and figure, neglecting of course a few trifling details due no doubt to individual variations. Pectoral fins.—In regard to the pectoral fins there are certain rather important differences between the account and figure given by Garman and the observations which I have made on three pairs of fins. The articulation of the fin with the coracoid is unibasal, and the articular surface of the mesopterygium is about twice as large as that of the propterygium. The propterygium is small, triangular in outline, and has a hollow articular surface. It carries no radials. The mesopterygiwm is moderately large, is irregular in shape, resembling somewhat a truncated triangle, not being nearly so triangular as that figured by Garman. It carries radials on its posterior edge which show various degrees of fusion. The metapterygiaum is an elongate, laterally compressed carti- lage, carrying a large number of radials. It has a rounded dorsal ridge and gradually curves outward, not being practically straight as represented by Garman. Usually it is bisegmental, but in this respect it presents some interesting variations, for in two fins which I have examined it is trisegmental. In the former condition the proximal segment is the longer one and is more laterally compressed than the distal segment. The trisegmental condition is represented in two ways; first by the addition of a small proximal segment articulating with the coracoid, similar to that figured by Braus (3), and second, by the intercalation of a short segment between the normal proximal and distal segments. Proc. Zoou. Soc.—1910, No. XXXVI. 36 562 MR. T. GOODEY ON THE SKELETAL [ Mar. 15, As a rule the metapterygium is attached by ligament to the coracoid, but I have found one case in which the mesopterygium interposes a short process between the metapterygium and the coracoid and so prevents this attachment. The radials are for the most part trisegmental, but the last two or three attached to the distal segment of the metapterygium are, as a rule, without segmentation. In the smaller tins which have been examined, two small post-axial radials are present; these are attached to the postero-lateral edge of the mesopterygium and are rot, as Garman figured them, in the same straight line as the metapterygium. In the larger fins from the female specimen, however, the two most distal radials of the meta- pterygium are attached terminally and not post-axially to it. The proximal segments of the radials attached to the meso- pterygium exhibit fusion, and in most cases the resultant mass of cartilage includes the first one or two of the proximal segments of the radials attached to the metapterygium, as shown in fig. 18. In some cases the whole of the proximal segments do not fuse as represented in the figure; one or two may remain distinct. Whatever ‘amount of fusion is shown, however, the original radials are indicated by lines of calcification in the fused cartilage. - I have entirely failed to find the nerve foramen figured by Braus (8) perforating the fused proximal segments to the radials attached to the mesopterygium. avails Tue Penyic GIRDLE AND FINS OF THE FEMALE. (Plate XLV. fig. 19.) - The pelvic girdle takes the form of a flattened plate of carti- lage, which is, as Garman pointed out, about twice as long as wide; it is also equal in length to the proximal segment of the basipterygium. On its anterior edge it has a median convex protuberance, whilst its posterior edge is practically straight, not bemg nearly so concave as Garman has figured it. Its lateral edge is almost straight, but has a few indentations, thus presenting a difference from the curved edge figured by Garman. A short distance from each side there is a row of foramina which transmit spinal nerves ; the second from the anterior end is the largest of these in all cases. In regard to these lateral foramina it is interesting to note that there is a certain amount of vari- ability in their number in different specimens of Chlamydoselachus. There is also a differenee in the number of foramina for each side of the girdle in one and the same specimen, as shown in the accompanying table :— No. of foramina: Specimen. R. side. L. side.

These would seem to correspond with the distal segmented portion of the basipteryginm and the two attached radials which I have figured; That the proximal one of these parts is a portion of the basi- pterygium is obvious from the figure (19), It carries, moreover, the penultimate radial. Garman’s figures (Pls. x1, & xii,) are scarcely to be trusted, as the two which he gives of these cartilages are different from each other in many respects, and particularly in regard to thé points in question, There is, it must be admitted, a certain amount of variability in these cartilages, for in the fin of the opposite side to the one figured the basipterygium is bisegmental distally and the attachment of the terminal radial is slightly different. Moreover, there are differences between the one figured here and those given by Goodrich (18) in his plate of fivures illustrating Chlamydoselachus. The lateral radials are attached to the ventro-lateral edge of the pelvic girdle and of the basipterygium. They are for the most part trisegmental, whilst those at the anterior end are somewhat irregular in outline and show signs of fusion in some of their parts. The proximal segments of those attached to the pelvic girdle are dorsally flattened and are directed outward, obliquely downward, and slightly posteriorly, The median and distal segments of these lie more in the horizontal plane and are more rounded than the proximal segments, The radials attached to the basipterygium are, on the whole, narrower than those attached to the girdle, and they gradually become more attenuated as we proceed posteriorly. The last one is bisegmental and the three before that are complete. The extraordinary length of the flattened pelvic girdle, the correspondingly large number of attached lateral radials, and the large number of lateral nerve foramina afford strong evidence of the primitive nature of the pelvic girdle in Chlamydoselachus.

I, GOODEY ON THE SKELETAL | Mar. 15, k. Haternals. Compared with the pectoral fins of the same specimen the pelvic fins and mixipterygia are quite large. As mentioned by Giinther (14) and as will be seen from the measurements given above, the edges of the pelvic fins reach to within a com- _ paratively short distance of the posterior ends of the appendages. On the dorsal side of each appendage, bounded by muscles, is the channel, which, toward its posterior end, becomes somewhat lateral in position and is bounded here by the knife-edged, movable terminal cartilages 7d. and Z7.v. In a ventral aspect the most prominent feature of the appendage is the glandular sac and compressor muscle, covered with loosely fitting soft skin. The sac does not extend anteriorly as far as the point of attachment of the basipterygium to the pelvic girdle. It may perhaps extend farther forward in more mature and larger specimens, or again it may be that the specimen under consideration was not taken at the period of sexual maturity, at which time the glandular sac enlarges considerably in most Elasmobranchs. The skin covering the sac and the terminal parts of the appendages is very soft and is entirely free from dermal-spines. 1. Musculature. In the following description I am adopting the nomenclature used by Huber (20), which differs somewhat from that used by Jungersen (21); more particularly in regard to the muse. extensor of the latter. This muscle Huber divided into musc. flexor externus and musc. flexor internws, both of which he found in all the examples on which he worked, I have found both also in Chlamydoselachus. Musc. adductor, A.—This is comparatively small, and has its origin in the posterior border of the pelvic girdle, to which it is attached by a strong ligament. It is partially overlaid by the muse. flexor internus, and is inserted on the inner distal end of the basipterygium. Muse. flexor externus, Fl.e.—This originates chiefly with 4, and on the inner surface of the latter, from which it later on separates. It is inserted on the proximal end of the muse. dilatator and also on the whole of the proximal side of the radial (3. Muse. flecor internus, Fl.1—This has its origin on the inner side of the basipterygium and is inserted on the proximal end of the axial cartilage 6. It is partially overlaid by the muse. flexor externus. Muse. dilatator, D.—This is a large muscle wrapping the inner and ventral surfaces of the axial cartilage 6. It has its origin on the proximal end of 6, partly beneath the radial 6, and is inserted chiefly on the inner side of the same cartilage and on the terminal cartilage Z7.d. It is also inserted to a much smaller 1910.] “ANATOMY OF THE FRILLED SHARK. 565 extent on the terminal cartilage Z.v. In the greater part of its extent 1t forms the inner lip bounding the channel. Musc. compressor, S.—On the dorsal side this muscle appears to arise from the outer side of 6. It really has its origin on the outer side of the proximal end of the axial cartilage 6, lying beneath 6. Contributing largely to it also on its outer side are muscle-bundles belonging to the last elongated lateral radials. These bundles belong to the system of dorsal radial muscles (0) which arise from the body-wall. The last elongated radial carries a portion of the musc. compressor on its inner side, thus forming the outer lip bounding the channel. On the ventral side the musc. compressor takes the form of a somewhat oval sac whose cavity communicates with the channel on the dorsal side of the appendage, and whose lining is of epithelium, continuous with that covering the appendage. Its tapering anterior end is attached to the aponeurosis below the last ventral radial muscle, whilst distally it is connected by loose soft tissue with the terminal cartilage 7.7. From the disposition of the whole muscle and from its relation to the other muscles of the appendage, I regard it as derived from modified muscle-bundles of the last two or three radials. This view is in agreement with Huber’s, according to which the musculature of the muse. com- pressor has originated from modified radial muscle-bundles of the last few radials. Radial muscles —On the dorsal side there are the muscle- bundles O, which have their origin in a lateral aponeurosis running along the lower ends of the myomeres of the body-wall. In removing these muscles it is found that they are indistinctly divided into two layers, a superficial one reaching as far as the horny fibres of the fin and a deeper layer which does not extend quite as far outward. On the ventral side there are the radial muscles Ra, which originate on the pelvic girdle close to the median line and extend outward to the horny fibres. Toward the anterior end the separate bundles have fused together, thus corresponding with the fusion of the radials above them. m. Skeleton. The following account is based on the dissection and exami- nation of the copulatory appendage of the right side, and on a careful comparison made with this and the appendages from another specimen in the museum here. The only previous accounts of the mixipterygia of Chlamydo- selachus are those given by Ginther (14), quoted by Jungersen (21) and by Braus (3). The mixipterygium figured by Braus is very different from that given by Gunther or that given in fig. 22 in the present paper. It appears to be in an undeveloped condition, for it is small and no terminal cartilages are shown. O66 MR. T. GOODEY ON THE SKELETAL [ Max’. 15, I have found a few rather important differences between the specimens which I have examined and those previously described and figured; these points will be dealt with in due course. The pelvic girdle resembles that of the female, being a flattened, elongated plate of cartilage. It has a convex anterior edge (another example had this edge slightly coneave) and a concave posterior edge. There area number of nerve-foramina perforating it at a short distance from each lateral border, the number of which has already been given. The basipterygiwm, B, is attached postero-laterally to the girdle, and there is a small piece of cartilage inserted dorsally in the attaching ligament, having the appearance of a portion segmented from the basipterygium, The latter is a fairly stout cartilage, is laterally compressed so that it is about twice as deep as wide, and is concave on its inner, and convex on its outer surface. It also has a rather prominent rounded ridge on its dorsal side, Attached to the dorso-posterior end of the basipterygium is the simple rod-shaped radial /3. This was not mentioned by Giinther, but Jungersen surmised that it was present and suggested that it had been overlooked. Braus has figured it. It is of interest to find that it is present, as it brings Chlamydoselachus into line with most of the described forms of Elasmobranch mixipterygia in this respect. The axial cartilage, b, is attached to the distal end of the basi- pterygium somewhat ventro- -laterally and toward the inner side. Lying in the thick connecting ligament is a single insignificant intercalary cartilage, 0.1, which Braus also has figured. The proximal end of the axial cartilage is comparatively thin and laterally compressed, In this respect, and particularly in respect to the single intercalary cartilage, there is here an important point of difference from Giinther’s figure. As shown in the latter, the axial cartilage 1s proximally broad and spindle-shaped, also one large and two small intercalary cartilages are shown closely, attached to it, the large one having the appearance of a portion, segmented from the axial cartilage. In view of the fact that I have found three axial cartilages narrow and somewhat com- pressed, with a single insignificant intercalary cartilage in each case, I can only suggest ‘that the large She ole cartilage ficured by Giinther is really a fractured portion of the anterior end of the axial eartilage, for it certainly has this appearance. With regard to the two smaller ones, it seems to me that the anterior one in his figure is really the base of the missing radial 6, whilst the intermediate one corresponds to the single intercalary cartilage. It is of interest to note also that the mixipterygium figured by Giinther is that of the right side, as is the one which is given in this paper ; but, curiously enough, the lateral radials in his figure are placed to the left of the basipterygium, whereas they are actually on the right side, as I have figured them. Proceeding towards its distal end, we find that the axial 1910. ] _ ANATOMY OF THE FRILLED SHARK. D67 cartilage becomes thicker and more rounded, attaining its greatest diameter at a point almost equidistant from each end, A groove now appears on its dorsal surtace to the right of the median line, and gradually deepens toward the distal end of the cartilage. This is the groove in the cartilage corresponding to the channel in the musculature. In his account of the claspers, Giinther says that the groove is on the ventral side of the axial cartilage, but how he arrived at this conclusion it is very difficult to imagine, especially as he figured it on the dorsal side. The groove is overhung in its deepest part by the forwardly curved, tongue-shaped marginal eartilage, &.v., which is attached basally to the outer border of the stem cartilage, and at its distal end to the ventral terminal cartilage, Z.v. The latter and the corresponding cartilage, 7’d., on the inner side of the appendage have sharp, chondrified cutting edges, and are movably attached to the lateral borders of the distal end of the axial cartilage. The ventral terminal, 7'v., is shorter than the dorsal terminal, Z\d., and its anterior end is more sharply pointed than that of the latter. The ridge corresponding in position to the dorsal marginal cartilage, 7.., of many other selachians is practically indistinguishable, and is certainly not as well marked in the specimens which I have examined as the ridge figured by Gunther. The lateral radials ave mostly trisegmental and, in general, they resemble those of the female pelvic fin, especially those attached to the pelvic girdle. Of these, the proximal segments are attached to the ventro-lateral edge of the girdle, and are directed outward, obliquely downward, and in a slightly posterior direction. ‘They are flattened on their dorsal surface and the three or four anterior ones exhibit fusion. Those attached to the basipterygium are more rounded and gradually increase in length as we approach the posterior end of the cartilage. The last two or three are not segmented, and this is a further point of resemblance to the condition prevailing in the female fin. There are differences in the examples that I have examined in the extent to which the anterior radials exhibit fusion, and also in the segmental or non-segmental character of the posterior ones. In regard to the latter point, it will be seen from a comparison of my figure with that given by Giinther, that whereas the last three radials are not segmented in my figure, only the last is complete in his. When the mixipterygium of Chlam:; ydoselachus 1s compared with that of Hexanchus griseus, described and figured by Huber, one is at once struck by the high degree of development pre- sented by the organ in Chlamydoselachus. Whereas in Hexanchus the axial cartilage is represented by a comparatively short cartilage, seureely distinguishable from .a lateral -radial, and bearing no accessory cartilages; the homologous part in Chlamydo- .selachus 1s a long, stout cartilage, furnished distally with three movable accessory cartilages. 568 MR.

It must, however, be pointed out that in his figure (Pl. xii.) the small distal segments of the trisegmental radials of the anal fin are absent. Firbringer (7) gives a good figure of the dorsal fin, and on account of this, and also because Garman’s figures of both dorsal and anal fins are in the main features correct, I have not deemed it advisable to give a drawing of these structures. X, SUMMARY. The following are a few of the most important points dealt with in the paper :— 1. The Membranous Labyrinth is described and figured for the first time, and it has been found to be of the usual selachian type, resembling rather closely that of Hexanchus griseus. 2. In the formation of the centra the following points are especially worthy of note :— (a) The presence, at the anterior end of the vertebral column, of well-developed, calcified cyclospondylic centra. (6) Slight constrictions of the notochord in the trunk region, best seen in horizontal longitudinal section, not calcified. The lowest stage in the development of centra. (c) In the main caudal region, calcified cyclospondylic centra of two sizes are present, corresponding with the doubling in the number of arcualia, which here, more than elsewhere in the vertebral column, grow round the notochord and greatly strengthen the centra. 3. The terminal caudal region is heterospondylic, and not monospondylic as in many other Selachians. 4, The musculature and skeleton of the mixipterygia are dealt with fully for the first time. In regard to the musculature I have to record the presence of both muse. flexor internus and muse. flecor externus of Huber. In the skeleton I have found the modified radial 3, and only one small intercalary cartilage 6.1, not three as recorded by Giinther. | XI. LITERATURE. 1.

Oeitvie-Grant, F.Z.S., M.B.0.U.f [Received March 15, 1910. ] The Natural History Museum has recently received a small collection of birds from the Five- and Seven-Finger Ranges, Cen- tral Hainan, procured by Mr. Robert Douglas, I.M.C., Shanghai. It was forwarded in the first instance as a present to the Zoological Society of London, but thanks to the good offices of the Secretary was transferred to the Natural History Museum. It contains several species of great interest, and among these examples of a new species of Wood-Shrike ( 7ephrodornis hainanus), and a new species of Ant-Thrush (Pitta douglasi) as well as a Bulbul (Pyenonotus sinensis), not hitherto found in Hainan. In my article on the Birds of Hainan published in 1900 239 species were enumerated as inhabiting the island. Since that paper was published My. Walter Rothschild has received a large collection of birds from the island of Hainan made by Mr. Alan Owston’s Japanese collectors and containing specimens of the beautiful Tree-Partridge (Arboricola ardens), hitherto known only from the type-specimen. Mr. Rothschild described the following species and subspecies (cf. Bull. B. O. C. xiv. pp. 7-9, 1903) :— Psittiparus gularis hainanus. Serilophus lunulatus polionotus. Stachyris. guttata swinhoer. Trochalopteron canorum owstoni. Stachyridopsis ruficeps goodsont. Pomatorhinus tickelli hainanus. Cissa katsumatee.$ The first of these, the so-called P. g. hainanus, does not appear to be distinct from Paradoxornis fokiensis David, for, as will be seen below, the difference in size is not appreciable. The species, how- ever, was not included in my former paper, so that the total number of species of birds now known to occur in Hainan amounts to 249. The number given for each species is the same as that used in my paper on the Birds of Hainan ; for the sake of brevity this is referred to as ‘ Ogilvie-Grant.’ 5 a. CissA KATSUMATA Rothsch.

Hainan examples of this Magpie appear to be somewhat smaller than Chinese birds. In six specimens the wing measures less than 5 inches, but in a seventh (a male) it attains a length of 5-4 inches. Three specimens have the middle pair of tail-feathers black to the base, and three show traces of grey, while in the seventh the basal half of the feathers is grey, as in the Formosan species, D. formose Swinhoe. Chinese examples may generally be distinguished from Hainan birds by their purer white upper tail- coverts, but these characters seem too variable to warrant the separation of the Hainan birds from typical D. sinensis. In certain respects they are intermediate between the Chinese and Formosan forms, the latter being always characterized by their greyer upper tail-coverts and the grey basal half of the middle pair of tail- feathers. Dr. Hartert has separated this bird as a subspecies under the name D. s. insule. 8. ACRIDOTHERES CRISTATELLUS (Gmel.). Ogilvie-Grant, p. 463. a,b. $6 @. Seven-Finger Mts. 16th November. Examples of this Starling from Hainan appear on the whole to be somewhat smaller than those from China, and have perhaps rather less white on the basal half of the primary quills. In six Hainan examples the wing-measurement varies from 4°8 to 5 inches, while in a seventh specimen it measures 5:25 inches. Dr. Hartert regards this bird as distinct and has named it A. c. brevipennis. 10. SpoDICPsAR SERICEUS (Gmel.). Ogilvie-Grant, p. 463. a. 2. Five-Finger Mts. 9th November. 11. Temnurus NicER (Styan).

On the Variation of the Sea-Elephants. By Dr. Einar Loynpure, C.M.Z8. [Received February 25, 1910. | (Text-figures 55 & 56.) Four years ago, when I wrote about the Sea-Hlephant of South Georgia*, the question arose in my mind whether the Sea- Elephants inhabiting the widely separated islands in the southern subantarctic seas all belonged to one and the same race. It appeared to me most probable that this was not the case, because the herds of the different islands are, and must have been for a very considerable time, completely isolated from each other, as these animals are not pelagic in their habits, but chiefly confined to the waters surrounding the islands on the shores of which they spend a great part of their lifetime. As, however, | had not sufficient material from ditferent localities for comparison, and the literature did not contaim enough to throw satisfactory hght on the matter, I had to leave it unsolved. It was therefore a great satisfaction to me when my friend Mr. R. Lydekker took up this question last year and published a paper “On the Skull-Characters in the Southern Sea-Elephant.” 7 Having read that paper, however, it appeared to me that the characters on which Lydekker has based the racial differences which, according to his views, exist between the Sea-Elephants belonging to four different geographic groups with subspecific value were rather unsatisfactory, when 1 considered the variation found in skulls of these animals which T had studied from material brought from South Georgia. In the paper quoted Lydekker diagnosed the following races :-— “1. Macrorhinus leoninus typicus, Juan Fernandez.” “2 M. 1. falclandicus, Falkland Islands.” “3. M. 1. macquariensis, Macquarie and (?) Chatham Islands.” “4. M. crosetensis, Crozet and (%) Kerguelen and Heard Islands.” According to later information Lydekker presumes that the Sea-Elephant of Juan Fernandez belongs to the same geographic group as those known under the specific name angustivostris, which latter name then should ‘be regarded as a synonym of leoninus, while falclandicus would become the substantive name for the Southern species” (/. ¢. p. 606). Lydekker bases the subspecific differences between the Sea- Elephants from the different islands on certain proportions and other characteristics of the skulls selected from the palatal surface. To prove the difference in proportions he quotes certain measurements in English inches from which the relations in * IC, Sv. Vetenskaps-Akad. Handl., Bd. x1. + Proc, Zool.

A comparison reveals, then, that with regard to this dimension three of Lydekker’s specimens, representing “JZ. 1. falclandicus ” and “ MW. 1. macquari- ewsis,” fall within the limits of variation for the Sea-Hlephant of 582 DR. EINAR LONNBERG ON THE [Mar. 15, South Georgia, but one of them, that regarded as the type of “ VW. 1. crosetensis,” is somewhat ditterent, showing a percentage larger than that of any of the adult skulls from South Georgia. Although a direct comparison between this Crozet Island specimen measuring 412 mm. and the quite young skull from South Georgia measuring 193 mm. (conf. the table) cannot be made, though the former is young also, it is of interest to find that the percentage expressing the relation between basal length and zygomatic width is almost the same in both, viz. 84°8 and 84:9. This depends in both cases on the shortness of the snout, which thus is a retained juvenile characteristic in the Crozet Sea-Elephant, if constant. If we then turn our attention to the length of the palate, this measurement will be found to vary from 49°5 to 56°5 per cent. of the basal length of the skull in the seven South Georgia male skulls. The figures expressing the same relative dimension in Lydekker’s specimens all fall within these limits and have thus no value as racial characteristics. The width of the palate varies in the South Georgia skulls from 32°2 to 37-1 per cent. of the basal length. ven in this feature Lydekker’s specimen from the Crozet Islands: is Somewhat aberrant as its corresponding percentage amounts to 39°3, thus indicating avery broad palate. In this respect the Crozet specimen does not exhibit a juvenile characteristic, for the corresponding percentages of three quite young males from South Georgia are from 34°5 to 35°7. Among other characteristics used by Lydekker for distinguishing his races of Sea-Elephants, he mentions the length of the imter- palatine suture, which he says is “long” in “‘falclandicus,” “shorter” in ‘ macquariensis,” and ‘ longer” again in “‘crosetensis.” It must be said, however, that the shape and size of the palatine bones in the Sea-Elephants are so extremely variable that no value whatever can be laid on any character derived from them. To prove this it may be mentioned that although, as a rule, the palate ends mesially behind in a projecting tip, there are other specimens also adult in which there is quite a deep palatine notch mesially. Not only depending upon this difference but because the bones themselves vary in size, the length of the interpalatine suture becomes very variable, as direct measurements indicate. Thus in the largest of the South Georgia skulls (conf. table of measure- ments) the interpalatine suture was only 30 mm. but in the next 81, in the next 57, then 62, 44, 61, and 68 mm. respectively. It was thus more than 2 times longer in the next largest skull than in the largest. The percentages expressing the relation between the basal length of the skull and the length of the interpalatine suture vary from 5:6 to 16°5, and not two of them agree (conf. the table). It is of interest to see that such a great variation in the size of the palatine is not only due to modifications during the growth at a somewhat advanced stage, but that already in quite young individuals a similar difference makes itself apparent -to the extent that the length of the interpalatine suture in one of two 1910.] _ VARIATION OF THE SEA-ELEPHANTS. 583 equally large quite young individuals is 5°6 per cent. and in the other 10°6 per cent. of the basicranial length (conf, table of measurements). The shape of the palate should also be different in Lydekker’s “ subspecies ” in i a way that it ought to be “ flat behind and hollowed in front” in “ falelandicus,” “ markedly hollow through- out” in “ MNF A corsa,” and “‘ almost flat” in ‘ crosetensis.” The skulls from South Georgia prove that the degree of ‘* hollow- ness” is very different in different specimens. In the largest skull, for instance, the palatina are markedly less “ hollow” than the maxillary region of the palate, and the lateral portions of the first mentioned bones are very strongly convex. In the second largest skull the whole palate from the posterior border is evenly and strongly vaulted. In the third largest skull the palate 1s much less ‘ hollow,” the palatina are almost flat and somewhat convex laterally. In the fifth largest the palatina are almost flat, but the remainder of the palate is very concave. In the sixth the palate is almost completely fiat, and in the seventh it is only a little “hollow.” There is thus almost every degree of ‘ hollow- ness” represented among these seven skulls, and characteristics derived from such a condition cannot be of subspecific value. Mr. Lydekker has also used the relative length of the ptery- goid processes as a distinguishing characteristic of subspecific value, saying that this process is “small” in “ falclandicus,” “longer” in “amacqueriensis,” and “very slender” in ‘“‘crosetensis.” Unfortunately, the pterygoid process is subjected to just as great individual variation as other portions of the Sea-Elephant skull. As Lydekker has not recorded any direct measurements with which a comparison can be made, it may be suitable to express its relative length by measuring the distance between its posterior tip and the nearest opposite point on the bulla. This distance measures in the seven skulls from South Georgia respectively 22 mm., 10 mm., 0 mm. (in this skull the pterygoid process forms a complete bridge over to the bulla.and is anchylosed with the same), 12 mm., 10 mm., 9 mm., and 4 mm. (the skulls are enumerated in the same order as in the table of measurements). As regards slenderness, the pterygoid process is always compressed and its longest diameter at the tip varies as the following measurements indicate: 10 mm., 13 mm., 15 mm., 19 mm., 15 mm., 12 mm., and 8mm. The variability of this bone may by this be fully elucidated. NOs palatal aspect of the premaxillaries 1 is said to be V-shaped rs falclandicus ” and “ macquariensis,” but U-shaped 1 in “ croset- ensis.” The present material from South Georgia proves that this characteristic is just as variable as the others. In the fifth and sixth of these seven skulls the V-shape of the palatal aspect of the premaxillaries is quite typical, but in the second and third the U- shape | is just as pronounced as in Lydekker’s figure of “ crosetensis” ; the others show intermediate features. The accompanying figures (text-fig. 55, A-D) show this different shape of the premaxillaries in the Sea- -Elephant from South 584 DR. EINAR LONNBERG ON THE _[ Mar. 15, Georgia. The length of the palatine surface of the premaxillaries varies without correspondence to age or size from 19-7 to 25-7 per cent. of the basal length of the skull (conf. table of measurements). Text-fig. 55. DY Shag DY \V ds D Cc Outline of palatal aspect of premaxillaries of four specimens of the Sea-Hlephant from South Georgia. Having thus examined and tried on the Sea-Elephant skulls from South Georgia all the characteristics which Lydekker regarded as satisfactory and distinctive, I have come to the con- clusion that all of them are extremely variable, and, with the exception of two characteristics of ‘“‘ crosetensis,” to which I shall return presently, and the width of the occipital condyles, which also will be spoken about later on, all the characteristics of Lydekker’s presumed subspecies are to be found within the limits of the variation of the South Georgia Sea-Hlephant. But this 1910.] _ VARIATION OF THE SEA-ELEPHANTS. 585 animal must for geographical reasons be just the one which Lydekker has named “ falclandicus,” which thus in itself unites most of the characteristics of all the others. he Sea-Elephants have long ago been exterminated on the Falkland Islands, and if now and then at the present time such an animal should be found there, it is a straying individual which has come there accidentally, most probably from South Georgia—an analogy to the fact that sometimes, although seldom, a Walrus appears at the Norwegian coast, in spite of the fact that the Walrus is as little pelagic in its habits as the Sea-Hlephant. The Sea-Elephant of the Crozet Islands Lydekker with some hesitation regards as identical with those inhabiting Kerguelen and Heard Islands. From a geographical point of view such an assumption appears quite probable. If, however, this assumption is accepted there is some material for the further consideration of the ‘‘crosetensis” form available in the literature, because Turner has, in his report on the Seals in the Scientific Results of the Voyage of H.M.S. ‘ Challenger,’ * communicated a table of measurements of Sea-Hlephant skulls, and among them are two male specimens from Heard Jsland and one male from Kerguelen Island. The lengths of the Heard Island skulls from premaxillary to occipital condyle are respectively 495 and 486 mm., and the same measurement of the Kerguelen skull is 402 mm. As the condyle has been included in these measurements the figures quoted are not directly comparable with those of the accompanying table, but by comparing the corresponding measurements of skulls at hand with the basal lengths of the same, it is easy to reckon how great a reduction is necessary to obtain the approximate basal lengths of Turner’s skulls. It cannot be many millimetres wrong to assume the basal length of the Heard Island skulls to be 470 and 464 mm. respectively and that of the Kerguelen skull to be 380 mm. The measurements expressing the zygomatic width and the greatest width of the palate of these skulls are also recorded in Turner’s table. If, then, the relations between these measurements and the basal length are reckoned in percentages of the latter, the following figures are obtained :-— Heard Island. Kerguelen. Zygomatic width in percent. of basallength 74:4 76:2 73-9 Greatest width of palate in percent. of 39-7 38:3 32-6 GRISEA LS Kernel dhas ep etne ane deeaneen enc tes cnenn The three former percentages fall all of them quite well within the limits of variation found in the South Georgia skulls as quoted above ; and if these specimens belong to the “ crosetensis” form, the zygomatic width of thesame is only in exceptional cases, asin Lydekker’s specimen referred to above, greater than in South Georgia specimens, i. e. “ falclandicus.” The zygomatic width is consequently no distinguishing characteristic between these two. Of the percentages expressing the relation of the width of the palate, the first and the last are rather low even for South Georgia * Zoology, vol. xxvi. p. 6. 586 DR. EINAR LONNBERG ON THE [Mar. 15, specimens. ‘The middle one again (38°3) is about one per cent. higher than the highest of the corresponding dimension of South Georgia specimens. From this fact and that recorded above from Lydekker’s Crozet specimen only one conclusion can be drawn, that sometimes the Sea-Hlephants of the Crozet-Kerguelen-Heard Islands geographic group have a greater palatal width than their relatives in other places so far as is known. It is not, however, a general rule and thus no distinguishing characteristic. With regard to other measurements also, the relative dimensions of the skulls from Kerguelen and Heard Islands measured by Turner vary within the same limits as the corresponding figures of South Georgia skulls. As an example may be mentioned that the width of the skull at the posterior edges of meatus audt- torius externus is in the South Georgia skulls from 61-9 to 68-4 per cent. of the basal length (conf. table of measurements), while the corresponding measurements of Turner’s skulls are respectively 64:4, 61:2, and 66°8. These latter measurements do not indicate any greater width of the skull than the corresponding figures of South Georgia skulls. Another example indicating a similar condition is obtained by comparing the width of the maxillary portion of the skull with the basal length. In this case I have measured the South Georgia skulls on a level with the upper posterior premaxillary suture. The percentages expressing this relation (conf. table of measure- ments) vary in the adult and semiadult males from 30:9 to 38°3 per cent., without corresponding with the size or age of the animals. With the above measurements may correspond fairly weil those recorded by Tur ner as indicating the “ width of maxilla across middle of rostrum” of Heard Island and Kerguelen speci- mens. If these then are compared with the basal length of the skulls (conf. above), the following percentages are obtained (enumerated in the same order as before): 34:0, 36-4, and 32:1. All these fall evidently within the limits of variation of the South Georgia material, and they do not at all indicate any greater rela- tive width of this portion of the skull im the Heard-Kerguelen animals than in those from South Georgia. In Turner’s table of measurements there are some figures indicating the “ smallest interfrontal width.” As I do not know whether this measurement coincides with the least frontal width according to my way of measuring, | cannot make any direct comparison, but only quote the percentages obtained. In the South Georgia material there is a vi ariation from 15:0 to 20°5, but the percentages reckoned from Turner's figures are respectively 15:1, 14:0, and 13-6, thus lower than the former. If Turner’s and my own measurements really coincide, as I believe they do, the percentages appear to indicate a narrower forehead in the Heard- Kerguelen Sea-EHlephants. The measurements hitherto considered show very plainly a quite irregular variation which does not correspond with size or age. But there is another relative dimension which exhibits a very 1910.] “VARIATION OF THE SEA-ELEPHANTS.. 587 beautiful series (conf. the table of measurements) in full corre- spondence with the size of the skull, and that is the width of the occipital condyles compared with the basal length of the skull. Text-fig. 56. Outline of the nasals of four specimens of the Sea-Hlephant from South Georgia. This percentage decreases regularly and gradually from the skull of the quite young animal to that of the oldest bull. Considering this fact, it is perhaps of importance that Lydekker states that the 588 ON THE VARIATION OF THE SEA-ELEPHANTS. condyles of his ‘“ crosetensis ’’ are “‘ extremely narrow.” To judge from his figure (/. ¢. p. 605) the condyles of the Crozet skull appear to be only about 20 per cent. of the basal length of the skull, although the latter measurement is said to be ‘16:5 ins.” or 412mm. According to the condition observed in the material from South Georgia, the condyles of such a small skull ought to have been something about 28 per cent. of the basal length. It is possible that this characteristic together with others—but hardly those discussed above—might prove that a racial difference exists in the geographic group represented by the Crozet skull. It is, however, difficult to base any opinion about this on a single skult when these animals have proved so extremely variable in their skull characters. Unfortunately, Turner has not communicated any measurements of the condyles of his skulls from Heard Island and Kerguelen Island. The Sea-Hlephant skulls from South Georgia show a quite irregular variation in many other respects than those already mentioned. The general shape of the nasals is, for instance, very variable as the accompanying four figures (text-fig. 56 A—D, p. 587) prove. The dimensions are also extremely different in different specimens with regard to length as well as to width, as may be seen from the table of measurements. The mesethmoid reaches the upper surface of the skull and fills up the mesial anterior notch between the nasals,; where it expands more or less in different specimens as the figures of the nasals show. By this a continued growth forward and ossification of the nasals in the mesial line is made impossible, but on either side of the meseth- moideum there is free space enough for such a growth and this might contribute to the irregular shape of the nasals. The exceedingly great variation of the Sea-Hlephant skulls appears to be fully proved by these notes, and it must certainly be regarded as a very interesting fact. This great variation 1s partly explained by the general rule that large mammals, the growth of which is continued through a long period of years, each of which contains different seasons with different conditions of life, are more apt to vary than such as conclude their growth within one year. Another factor which also may be of some importance in this connsction is that the Sea-Hlephants originally had hardly any dangerous foes which could influence a natural selection. Now, however, these very interesting and completely harmless sea- monsters have been unfortunate enough to provoke the most dangerous of all foes—the greediness of man ; and by this they are threatened with extinction even in the few remote places where they may still exist in limited numbers. Indeed, the Southern Sea-Hlephant is doomed to share the sad fate of its Californian relative if speedy measures are not taken for its protection. The hope of zoologists and al] friends of living nature is that the the Government of Great Britain may give this protection which is so sorely needed. No. 80. ABSTRACT OF THE PROCEEDINGS OF THE ZOOLOGICAL SOCIETY OF LONDON March 1st, 1910. Dr. A. Smira Woopwarp, F.R.S., Vice-President, in the Chair. The Minutes of the last Scientific Meeting were confirmed. The Secretary exhibited photographs of a Thylacine (Thyla- cinus eynocephalus) and three cubs which had been sent him by Mrs. Mary G. Roberts, C.M.Z.S., of Hobart, Tasmania. Mrys. Roberts had informed him by letter that the Thylacines had been in her possession for about eight months, and were tame and playful, and that the mother had nursed them until they were nearly as large as herself, although throughout that time they had also taken raw meat. Mrs. Roberts added that the Thylacine had extremely strong maternal instincts and that these animals, in her opinion, were not of low intelligence. The Srcrerary called attention to the recently published ‘Camera Adventures in the African Wilds, by A. Radelyffe Dugmore, remarking on the great additions to knowledge of wild animals that were being obtained by this new form of sport. He directed special attention to the photographs of Grévy’s Zebra, obtained near the Guaso Nyiro River, not far from Mt. Kenia, as evidence of the range of that: species, and to an extremely interest- ing photograph of the Giant Bush-Pig (Hylocherus meinertz- hageni) taken in the same locality. Mr. R. H. Burne, F.Z.S., exhibited a preparation of the vena cava inferior, diaphragm, and liver from a Seal (Phoca vitulina) that had recently been living in the Gardens. The specimen * This Abstract is published by the Society at 3 Hanover Square, London, W., on the Tuesday following the date of Meeting to which it refers. It will be issued, along with the ‘ Proceedings,’ free of extra charge, to all Fellows who subscribe to the Publications ; but it may be obtaimed on the day of publication at the price of Sixpence, or, if desired, sent post-free for the sum of Six Shillings per annum, payable in advance. 14 showed the strong sphincter muscle (derived from the diaphragm) that encircles the lower end of the thoracic segment of the vena cava, the great dilatation of this vessel below the diaphragm and within the liver, and the presence of a pair of venous plexuses in connection with the cava midway between the diaphragm and the heart. Mr. Frank E. Bepparp, M.A., F.R.S., F.Z.8., Prosector to the Society, exhibited a series of specimens of Harthworms from Luzon, Philippine Islands. Dr. C. W. Anprews, F.R.S., F.Z.S., exhibited and made remarks upon some teeth of Hlephas (Stegodon) insignis and of a species of horse from China. The former were from Sze-chuen, probably from beds of Lower Pliocene age, and were sent to the British Museum by the Rev. W. C. Taylor, of the China Inland Mission. The horse teeth were from Tsi-shan, N. China, from a depth of about 300 feet in the Loess, probably of Pleistocene age: these were sent by the Rev. R. Gillies, also of the China Inland Mission. Dr. R. T. Luteer, F.Z.8., exhibited the larval stage of Tricho- strongylus pergracilis, the causal factor of Grouse disease. He found experimentally that the development follows almost exactly the same course as that of Ankylostome—the cause of miner’s disease in Cornwall. The egg developed into embryos in about two days, and metamorphosed on the eighth day into a peculiarly active larva that climbed heather only in wet weather. These larvee were found in extraordinary numbers on the plants, the roots of which were experimentally infected. Subsequent drying did not kill the larvee, for by encysting they could survive several weeks without additional moisture, but were unable, however, to resist desiccation. They underwent no further developmental change, and this stage, when fed to healthy Grouse, alone was able to produce infection, and within four days eggs were found in the droppings. Dr. Leiper also exhibited a specimen of Cyclops containing a living embryo of Cucullanus elegans, a blood-sucking parasite of Perch, and discussed the mode of entry into Cyclops of this worm and the guinea-worm. Experiments showed that the embryos only penetrated living Cyclopidz, and led to the conclusion that the Cyclops actually swallowed the living embryos and these penetrated the stomach. The paper by Mr. J. Lewis Bonnors, M.A., F.LS., F.Z.8., “On the Varieties of Mus rattus in Egypt, with General Notes on the Species having reference to Variation and Heredity,” announced for this evening’s Meeting, was postponed owing to the unayoid- able absence of the Author. es 15 Sir Grorcz F, Hampson, Bt., F.Z.S., presented a paper giving a list of the Moths collected by Mr. Shettield A. Neave, F.Z.8S., in Rhodesia north of the Zambesi and the adjacent Katanga District of the Congo Free State, nearly two hundred new species being described. The Moth fauna of the district is mainly of a West African type, with a considerable admixture of Hast African and Mashona- land forms. As there are no high ranges of mountains or deep river valleys the fauna presents a very uniform tropical African character, with no high mountain forms or forms peculiar to the faunas of the drier parts of Southern or Northern Africa. The Secrerary read a paper on “The Urogenital Organs of Chimera monstrosa,’ by T. H. Burtenp, M.A., B.Sc., communi- cated by Prof. W. N. Parker, Ph.D., F.Z.8. This paper dealt with the urogenital organs of Chimera, both immature and adult of each sex. Much of the early work of Leydig and Hyrtl, which later writers had ignored or disputed, was now confirmed and supplemented. The kidney of the young male became differentiated at maturity into an anterior portion, the “ Leydig’s gland,” with a function like that of the prostate gland of higher vertebrates, and a posterior portion, which retained its urinary function. Concomitant changes occurred in the structure of the sperm-duct. Vasa efferentia were present in the male, and these passed directly into a collector with which the sperm-duct was continuous; hence an epididymus, as usually defined, was absent. The adult female was shown to lose the distinct urogenital sinus found in the young animal ; further, the term “digitiform gland” was suggested as more suitable for the structure usually called the “‘ receptaculum seminis.” The next Meeting of the Society for Scientific Business will be held on Tuesday, the 15th March, 1910, at half-past Hight o'clock p.m., when the following communications will be made :— 1.

ABSTRACT OF THE PROCHEDINGS OF THE ZOOLOGICAL SOCIETY OF LONDON.* March 15th, 1910. K. T. Newton, Esq., F.R.S., in the Chair. The Minutes of the last Scientific Meeting were confirmed, The Secretary read a Report on the additions that had been made to the Society's Menagerie during the month of February 1910. The Sucrerary read an account of some post-mortem pheno- mena observed by Mr. E. W. Shann, B.Sc., in a specimen of Lemur fulwus rufifrons which died recently in the Zoological Gardens at Giza, Egypt. Mr. OupFieLp THomas, F.R.S., F.Z.S., exhibited the skin of a new Potto from British Hast Africa, which was proposed to be called PERODICTICUS IBEANUS, Sp. n. Fur very thick and soft. Colour of upper surface grizzled hoary grey, except the shoulders and fore-back, which were blackish. Teeth comparatively small. Head and body 359 mm.; tail 68; skull 64. Hab. Kakamega Forest, British Hast Africa. Type. Male. B.M. no. 10.3.18.1. Presented by Messrs. Matison and Brett. Mr. D. Sera-Smirz, F.Z.S., Curator of Birds, gave an account of some living examples, in the Society’s Gardens, of the Black- hooded Parrakeet (Psephotus cucullatus). * This Abstract is published by the Society at 3 Hanover Square, London, W., on the Tuesday following the date of Meeting to which it refers. It will be issued, along with the ‘ Proceedings,’ free of extra charge, toall Fellows who subscribe to the Publications ; but it may be obtained on the day of publication at the price of Stxpence, or, if desired, sent post-free for the sum of Six Shillings per annum, payable in advance. 18 The Secretary read a letter from Mr. George Jennison, of the Manchester Zoological Gardens, giving an account of the success- ful breeding of Pine-Snakes in confinement. Mr. Cares S1ttem exhibited some living specimens of the Crustacean Chirocephalus diaphanus recently caught in a fleoded diteh on Eton Wick Common. Mr. T. Goopry, M.Sc.(Birm.), introduced by the Secretary, gave an account of his Memoir entitled “A Contribution to the Skeletal Anatomy of the Fish Chlamydoselachus anguineus, Gar.” The Author dealt with the anatomy of the axial and appendi- cular skeleton, paying particular attention to the structure of the notochord. He stated that the notochord in this fish had generally been regarded as unconstricted except at the extreme anterior extremity, but that he had ascertained the presence of well- developed, calcified eyclospondylic centra at the anterior end of the column and of calcified cyclospondylic centra of two sizes in the main caudal region. Mr. W. R. Ocitvin-Grant, F.Z.8., read a paper entitled ‘‘ Ad- ditional Notes on the Birds of Hainan,” based on a small collection of Hainan birds recently forwarded to the Zoological Society by Mr. Robert Douglas, of Shanghai, and, at the suggestion of Dr. Chalmers Mitchell, F.R.S., presented to the Natural History Museum. The collection contained several species of great interest, and the two following were described as new :— 'TEPHRODORNIS HAINANUS, Sp. Nh. Adult male. Differs from Indian examples of 7’. pelvicus Hodgs. in having the mantle and back much darker and of a reddish- brown colour. Adult female. Darker and browner above than the female of T. pelvicus Hodgs. Hab. Seven-Finger Mountains. PITTA DOUGLASI, sp. n. Adult male. Most nearly allied to P. soror, Wardlaw Ramsay, from Cochin China, which it resembles in having the crown and occiput dull bluish-green like the back, lower back and rump bluish; the fore part of the head, cheeks, ear-coverts, and lower part of the throat dull pink, chin inclining to whitish, lores, feathers surrounding the eye and on either side of the occiput rust-red ; chest very similar but tinged with pink; breast and rest of underparts buff; lower part of the abdomen whitish, upper wing-coverts and scapulars greenish-blue like the mantle; quills brown, margined on the outer web, especially towards the extre- mity, with pale brownish-buff, the five outer primaries white at the base of the inner web; tail greenish-blue like the back. Total length ca. 80 inches; wing 4°45; tail 2°05; tarsus 2°0. 19 Adulé female. Differs from the male in being less brightly coloured; the top of the head, occiput, and nape being olive- brown suffused with pink, and the rest of the upperparts, in- cluding the wing-coverts and scapulars, mostly dull olive-green ; the chest buff (instead of rust-red) tinged with pink, and the rest of the underparts paler buff. Total length ca. 7:6 inches; wing 4:4; tail 1-9; tarsus 18. Hab. Seven-Finger Mountains. Among the rarities attention was called to the remarkable Magpie (Temnurus niger) with its curious truncate tail-feathers, the beautiful Green Jay (Cissa katsumate) recently described by the Hon. Walter Rothschild, F.Z.S., and a Bulbul (Pycnonotus sinensis) not hitherto recorded from the island. The SrcRETARY communicated a paper by Dr. Einar LONNBERE, C.M.Z.S., “ On the Variation of the Sea-Hlephants.” The next Meeting of the Society for Scientific Business will be held on Tuesday, the 5th April, 1910, at half-past Hight oclock p.m., when the following communications will be mace :— 1.
