﻿802 HALLO WELL UN THE 



nucha to the end of the tail, but denticulated irregularly with brown upon the edges, 

 and marked with isolated salient black points, few in number, upon the dorsal region. 

 The under part of the body, from between the angles of the jaw, the neck, the belly 

 and under part of tail, as well as the under part of the members, of a yellow or saffron 

 colored tint, with regularly defined margins. 

 Habitat. — Pyrenees. 



Triton subcristatus, Sclilegel, 



Char. — Body warty, head large, flat and obtuse ; lateral tubercles at the commence- 

 ment of the neck ; upper part of the body of a more or less deep brown, with a small 

 dorsal crest, as it were, effaced; under part of the body red, with irregular very deep 

 black spots ; the under part of the extremities of the same red color, with some small 

 spots or black points. (Gen. Gynops, Tschudi.) — D. & B. 



Habitat. — Japan. 



Gen. Remarks. — Dumeril and Bibron say that Tschudi has separated this animal 

 from the Tritons, giving it a name indicative of no character, supposing that the 

 tongue was adherent throughout, but in the account of this genus in the German of 

 Tschudi, the only mention I find made of the tongue is that it is " sehr klein," very 

 small. The generic characters are based upon the differences in the osteology of the 

 skull, which, he says, is quite different from that of Triton. Not having the specimens, 

 we cannot determine this point. Gray mentions the tongue as adherent, scarcely free 

 on the edges. — Cat. Br. Mus., p. 24. 



Dumeril and Bibron consider it as allied to Euproctus, Bonaparte and Gene. Du- 

 meril and Bibron, besides the above, describe five species from the Pyrenees, collected 

 by Bibron, viz. : rugosus, cinereus. repandus,punctulatus and Bibroni, which according 

 to A. Dugis and M. Gervais, as stated by them, are varieties of Euproctus rusconi. 

 For description of them, see their work, p. 150 — 154, t. ix. 



DIEMYCTYLUS, Baf. 



Char. — Tongue small, ovoid, adherent in front and superiorly, somewhat less at the 

 sides ; no transverse palatine teeth ; two longitudinal series of palatine teeth in contact 

 in front, diverging posteriorly ; posterior nares quite large ; two longitudinal ridges 

 upon the cranium in contact in front, diverging posteriorly ; a bony bridge above the 

 orbit, as in Gynops and Euproctus ; spinous processes of vertebrae quadrangular, com- 

 pressed, laterally well developed ; three foramina on the sides of the head, not com- 

 municating with the mouth ; first and fifth toes rudimentary. 



Gen. Remarks. — Diemyctylus, as observed by Prof. Baird, appears to be closely 

 related to Gynops, Tschudi, Molge pyrrohogastra, Boie. Isis ; 1826, p. 215, Triton subcris-
