 Bibr.), Gthr. Batrach. p. 115. 



This species grows to a larger size than was hitherto known, there 

 being specimens in the collection the body of which measures three 

 inches, and the posterior extremity four inches and a half. In such 

 very large specimens the crown of the head becomes rough, as in 

 Trachycephalus, although without ridges, and with the skin not 

 tirmly adherent. 



9. Phryniscus LiEvis, Gthr. Batrach. p. 43. 



This species is subject to such variation of colour, that it may 

 prove to be identical with Phryniscus varius, which perhaps has been 

 established from specimens which had lost the prickles on the sides. 

 Among the numerous specimens sent by Mr. Fraser are several of 

 a dark bluish-green ground-colour, and with green spots on the back. 

 Others are greenish-grey, with the back spotted with black and yellow ; 

 each phalanx with a green spot. Others are intermediate between 

 these and the black variety.

1. CcECILIA ROSTRATA, CuV. 



The habitat of this scarce species has not been hitherto known with 

 certainty, 



2. CcECiLiA GRACILIS, Shaw. 



The circular folds are more distinct than is stated by Dumeril, 

 but become very inconspicuous towards the anterior part of the body. 

 The length is to the diameter of the body as 115:1. 



3. CcECILIA PACHYNEMA, n. Sp. 



Biagnosis. — The length of the body is to its greatest diameter as 

 92:1; body with 1 68 folds ; muzzle depressed, rather truncated 

 anteriorly ; posterior extremity of the body obtusely rounded, very 

 short behind the vent. 



Description. — This species, which is based on a single specimen in 

 the collection, belongs to those with the body elongate, and is distin- 

 guished from C. gracilis by having the folds very distinct from behind 

 the head. The folds do not reach entirely round the body, being- 

 smoothed down on the dorsal and ventral side. The body is covered 

 all over with rudimentary scales, which have more the appearance of 

 minute granulations. The folds on the posterior portion of the body 

 are not deeper than the others, nor do they contain any scales, as in 

 C. gracilis. The head is depressed, with the muzzle obtusely rounded 

 or rather truncated anteriorly, although overlapping the anterior 

 portion of the cleft of the mouth. The latter is wide, reaching as 

 far backwards as the head. The upper and the lower jaws are armed 

 with five hook-like teeth, directed backwards on each side, the anterior 

 of which (and, among these, those of the mandibula) are the strongest. 

 The palate has three similar teeth on each side. I cannot find any
