CADUCIBR ANCHIATA. Ill 



moderate; inner toes very long and free; feet flattened, 

 with two well marked plantar tubercles; tail much com- 

 pressed, with a membrane or fin above and below. 

 Length 4^ inches. Head to gular fold 7 lines. 



Tail 2 " Breadth of head 5^ " 



Habitat Europe and Northern Africa. Common. 



Dumeril and Bibron (12, b) recognize three varieties. 

 A. Very large, 8 inches long, black above, and the white 

 lateral points wanting. B. Length four to five inches, 

 brown above, or grayish in the males. C. Triton car- 

 nifex, Laurenti, are females of small size, without dorsal 

 crest. 



In a specimen before me from Leeds, England, one 

 hind foot has seven toes, of which the anterior three are 

 distinct, the other four all united at the base, and in 

 pairs towards the tips, the pairs being digitally distinct, 

 and each toe separate at the very tip. In other speci- 

 mens this abnormal development (which is probably a 

 result of injury) does not occur. 



Cope (31, g) describes as Triton subcristatus an ani- 

 mal which probably belongs here. The only points of 

 difference which appear in his description are the absence 

 of the white lateral dots, and the relative length of the 

 tail. He also quotes Schlegel to show a different osteol- 

 ogy for the head and a less number of vertebras, both 

 of which, without seeing the specimen in question, seem 

 to me doubtful. 



Habitat Loo Choo Islands.
