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. 

 lungers 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. 



Two 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 IT. carnea, Cope, 

 but the tympanum is perfectly distinct and the coloration is entirely 

 different. 



Dermophis 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 

 (duplicated), 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. thomcnsis, Bocage, by 

 Dr. Giinthe'r (P. Z. S. 1894, p. 88). The latter species (PI. XL. 

 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. XL. fig. 5).
