Show 646 BATRACHIAN COLLECTION IN THE BRITISH MUSEUM. [Nov. 6, HYLELLA PARVULA. (Plate XL. fig. 3.) Tongue circular, entire. Head as long as broad; snout short, rounded ; no canthus rostralis ; eye large and very prominent; upper eyelid very narrow; interorbital space broad and convex; tympanum distinct, hardly one third the diameter of the eye. Fingers distinctly webbed at the base, first slightly shorter than second; toes two-thirds webbed; disks moderate. Tibio-tarsal articulation reaching a little beyond the tip of the snout. Skin smooth above; belly and lower surface of thighs granulate. Greyish or pale brown above, speckled with white ; lower parts white. From snout to vent 17 millim. T w o specimens. One from Lages, Santa Catharina, collected by Hr. Michaelis; the other from Theresopolis, presented by Dr. Gbldi. This species appears to be most nearly allied to H. camea, Cope, but the tympanum is perfectly distinct and the coloration is entirely different. DEBMOPHIS GREGORII. (Plate XL. fig. 4.) 15 teeth on each side of the upper jaw, 12 on each side (outer row) of the lower jaw. Snout rounded, moderately prominent; eyes distinct, the distance between them a little less than the length of the snout; tentacle in front of and below the eye, twice and a half as distant from the nostril as from the eye. Body moderately elongate; 160 folds, the posterior close together (duphcated), all except the anterior and posterior interrupted above and often also beneath. Tail indistinct, rounded. Dark brown above, paler beneath. Total length 280 millim.; greatest diameter of body 10 millim. A single specimen was obtained at Ngatana, E. Africa, by Dr. J. W . Gregory. It was referred to D. thomensis, Bocage, by Dr. Giinther (P. Z. S. 1894, p. 88). The latter species (PI. X L . fig. 5) differs in the more pointed snout, the length of which does not exceed the interocular width, and the distance between the tentacle and the nostril is four to five times as great as between the tentacle and the eye (cf. PI. X L . fig. 5). EXPLANATION OF THE PLATES. PLATE XXXLX. Fig. 1. Bana quecketti, Blgr., p. 643. . 2. Phrynobatrachus ranoides, Blgr., p. 644. 3. Cassina obscura, Blgr., p. 644. 4.
