As in almost every part of Africa, this species varies wonder- fully in colour and markings, even in specimens obtained from the same pools, where they congregate for breeding. Some have much crimson or pink on the back of the thighs and in the groin, whilst others are entirely deprived of the brilliant colour. The most remarkable specimens are from Woodbush, and might be well thought to indicate a distinct species, were they not connected with the more typical form by every possible gradation. The young have the upper surface of the snout as far back as a dark interocular bar, and the parotoid glands, of a beautiful pink; part of the back is also pink, with grey markings with a fine black border ; the pink ground-colour appears as a dagger-shaped mark ing on the back. These markings become more indistinct with age, and the pink colour gradually fades away or disappears entirely. By a curious inversion of the ground-colour and the markings, some out of a number of specimens from Zoutspansburg are grey with pink markings. Four of these remarkable speci- mens are figured on Pl. XXI.+ In some of the specimens from Beira, the parotoid glands are exceptionally so flat as to be hardly distinguishable. * P.

Male with two external vocal sacs, opening by a slit on each side of the throat. From snout to vent 48 millim. Two males and one female, found breeding in a rain-pool at Beira in February. This species is very closely related to R. ornata Peters, from KE. Africa, and £&. ornatissima Bocage, from Angola. It differs from the former in the shorter web between the toes, from the latter in the much smaller size, in the shorter and less pointed snout, and in the shorter hind limbs. The white markings in front of the eye and under the throat are very similar in the three species. Another very close ally of R. ruddi is R. moeruensis Blgr., from Lake Mweru, which differs in the longer first finger, the longer hind limbs, the very prominent dorso-lateral glandular fold, and the coloration. 10.

The male has an external vocal sac on each side of the throat and a large flat gland on the front side of the arm (humerus), as in the Burmese &. granulosa And., R. hwmeralis Blgr., and &. oatesi Blgr. T avail myself of this opportunity to point out that the Frog named by me R. elegans, which had been previously confounded with the West-African £. albilabris Hallow., is identical with R. guenthert Blgr., and must therefore be erased from the list of African species. + Specimens of R. nutti Blgr. have been erroneously referred to R. bravana by Tornier. 99 Bol 482 MR.

The adults (shells only) have the black radiating streaks on the cara- pace, and the extent of the suture between the anal shields varies considerably, as may be seen from the annexed figure (text-fig. 140) representing the hind lobe of the plastron in two adult females, showing two extreme types in the series sent by Mr. Grant. Although the fore limb has five claws in the specimens from Mashonaland § and Zululand examined by me, the young from Beira has only four, and would therefore be referable to C. nogueyi. **3 STRERNOTHH®RUS NIGRICANS Donnd.

This species varies considerably in its lepidosis, and I do not think P. intermedius Matschie entitled to stand. Of the eight specimens from Woodbush three are males and five are females. The males belong to the guttatws type of coloration, have the lower parts of the head, body, and limbs dark blue, and the tail red; the females have three whitish longitudinal streaks in addition to the light spots on the head and body, the tail is pale yellowish brown, and only the middle of the belly is bluish black. The occipital shield is small or very small and, except in one specimen, the parietals form a suture separating it from the interparietal; the frontonasal is in contact with the rostral. 3 3 3 ? ? ? ? $ Length to vent (in milli- metres) .................. 105 97 90 87 83 80 77 58 Number of scales across bodyaeeee ces ZO 72 78 80 78 75 83 70 Longitudinal rows of ventral plates ......... 16 16 16 18 16 18 18 16 Number of femoral pores (right & left) .......... 16-17 17-16 17-16 19-19 16-16 19-20 17-18 17-18 Having now examined 15 specimens which I refer to P. gut- tatus, 1 find the scales across the body to vary from 70 to 90, the longitudinal rows of ventral plates from 16 to 20, and the femoral pores on each side from 15 to 20.

JAMES RITCHIE ON HYDROIDS [May 28, 3. On Collections of the Cape Verde Islands Marine Fauna, made by Cyril Crossland, M.A. (Cantab.), B.Se. (Lond.), T.Z.8., of St. Andrews University, July to September, 1904.*—The Hydroids. By James Rirconiz, M.A., B.Sc., Fullerton Scholar, University of Aberdeen fT. [Received April 18, 1907. | (Plates XXTIT.—XX VIE and Text-figures 142-144.) The forms described in the present paper were entrusted to me for determination by Mr. Crossland, who collected them in various localities off the Cape Verde Islands. Although the collection is not a large one, it forms a useful addition to our rather meagre knowledge of the Hydroid fauna of the northern portion of the west coast of Africa. To the north of the Cape Verde Islands specimens have been recorded from the Canary Islands, from Madeira, from the Azores, and from the Soudan coast; from the south the ‘Challenger’ records a solitary species, Cryptolaria diffusa Allm. from Sierra Leone; while from the islands them- selves, so far as I can learn, records have been made by only four workers §. In 1883 Allman, in his Report on the Plumularians collected by the ‘ Challenger, described the type of a new genus, Streptocaulus pulcherrimus Allm., found at Porto Praya in 100 fathoms. In July 1885 Mr. J. J. Quelch described a small collec- tion of deep-sea Hydroids, comprising nine species, and obtained from the cable off St. Vincent in a depth of over 500 fathoms, the species described being Hudendriwm annulatum Norman 1864, Lafoéa tenellula Allman 1877, Zygophylax profunda Quelch 1885, Plumularia variabilis Quelch 1885, P. delicatula Queleh 1885, Antennularia irregularis Quelch 1885, A. profunda Quelch 1885, Aglaophenia acacia Allman 1883, and Streptocaulus pulcherrimus Allman 1883. More recently Professor J. Versluys has described two species from Isle Branco, one of the Windward Group, Sertularia (Desmoscyphus) brevicyathus (Vers. 1899), and Desmo- scyphus inflatus Vers. 1899, a synonym for the D. gracilis of Allman 1888, which has been’ renamed Sertularia versluysi by Professor Nutting (1904). Of these the latter occurs in our collection, with the important addition that the gonosome is also present and is here described for the first time. Lastly, within the past month or two collections made by the ‘ Talisman * in 1883 have been described by Dr. Armand Billard (1907), and these include a few species from two localities off the Islands. In lat. * The expenses of Mr. Crossland’s collecting trip were borne by the Carnegie Trustees. + Communicated by the SecrRETARY. t+ For explanation of the Plates, see p. 514. § Since this paper was written I have found in the collections made by the Scottish National Antarctic Expedition on its homeward voyage two species from St. Vincent which were not represented among the specimens described in the Report on the ‘Scotia’ Hydroid Collection (Ritchie, 1907). These are Hucopella cenata? Hartlaub, 1901, and Sertularella fusiformis ? Hincks, 1861, both of which are additions to the recorded Hydroid fauna of the Islands.

(Paris 0°) at a depth of 105 metres there were obtained Diphasia pinaster (Klis & Sol. 1786), An- tennularia ramosa Lamarck 1816, and Thecocarpus myriophyllum var. bedoti Billard 1907. In lat. 16° 52'-16° 53’ N. and long. 27° 30'-27° 26’ W. at a depth of 400-580 metres, Diphasia pinaster and Thecocarpus myriophyllum bedoti were again found. The present collection is littoral, the greatest depth at which specimens were gathered being 15 fathoms, while the majority were obtained in shore-pools or in quite shallow water. Hence it is not surprising to find that of the species previously described from the Islands only one, Sertularia versluyst above mentioned, should recur among Mr. Crossland’s specimens. The collection contains in all 27 species, of which 18—one of them here represented by a new variety—have been previously described. Several of these species, which are distributed among 14 genera, have been recorded from more than one locality. For the remaining specimens 9 new species have been established, one species being referred to a new genus. In all representatives of 20 genera occur in the collection. The list of species is as follows :— I. GYMNOBLASTEA. Family CoRYNID®. Coryne (2) dubiwm, sp. 1. Family PENNARIID&. Pennaria cavolinii Ehrenberg 1832. Family TUBULARIID®.

Of the 18 hitherto known forms above mentioned, 10 are recog- nised as British species, while 5 of the remainder (Campanularia ptychocyathus, Sertularia mayert, S. versluysi, Lytocarpus grandis, Monostechas quadridens) are, with the exception of the last which has been recorded from the Indian Ocean (Thornely, 1904), distinctively American. This contingent is probably to be ac- counted for by the oceanic whirlpool the centre of which is marked by the Sargasso Sea and the streams of which wash the shores of the West Indies, of eastern Mexico, and of the eastern United States, and, circling in the North Atlantic, sweep past the Azores, Madeira, and the Cape Verde Islands. The collection, as might be expected in a littoral one, is com- paratively rich in gymnoblastic forms and includes an interesting species, peculiar in branching and in gonophore, which has been made the type of a new genus, Soleniopsis. We note also, as Pictet has already remarked (Pictet, 1893), that of those species which occur both in temperate and in tropical waters, the individuals existing in the colder seas are, in general, larger and more sturdy than their tropical specific equivalents. The outlines of the figures, both in the plates and in the text, with the exception of those representing the appearance of the specimens to the unaided eye, were drawn with the help of Zeiss’s camera lucida.

The stem is slender, 0°l mm. in diameter, and soon breaks up into very numerous, irregularly disposed branches which, arising at a small angle, lie for a short distance almost parallel with their parent shoot and thereafter gradually diverge from it. Branches even of the fourth order are present. The colonies are wrinkled throughout, but less strongly in the middle portions of the polyp- bearing branches ; while beneath the polyp, on the stems, and on the older portions of the branches distinct ringing occurs. There is no membranaceous cup surrounding the base of the hydranth. The hydranths are relatively long, 0°5 mm., slightly bulging beneath and tapering gradually upwards towards the tip and down- wards to form a long “neck.” The tentacles are from 0:1 to 0:15 mm. in length, and except for the distal four, which generally appear to be placed in a whorl, are scattered. They vary slightly in number. Thus of 10 heads examined, one bore 12 tentacles, four bore 13, three bore 14, and on two 15 were found. Gonosome not present. Locality. Growing on a seaweed taken from piles of pier. Porto Praya, Santiago, Cape Verde Islands; 12th August, 1904. Owing to the absence of the gonosome this species cannot be given a definite generic place within the family Corynide as defined by Delage (1901). Notwithstanding I have assigned a specific name to the form in order to facilitate references. The trophosome characters lie between those of
