86 TRITON INGENS. 



Colour. The whole animal above is bluish slate-colour, marked with irregu- 

 larly sub-ovate pale ash-coloured blotches, disposed without order. The lips and 

 throat are dark brown; the belly is slate-colour. 



Dimensions. Length of head, 1 inch; length of body to vent, 4 inches; length 

 of tail, 5 inches: total length of the animal here described, 10 inches. I have 

 seen one specimen more than 12 inches long. 



Habits. I know nothing of the habits of the Triton ingens, save that it is 

 entirely an aquatic animal. 



Geographical Distribution. This reptile has as yet been observed only in 

 our western waters. Professor Green received his first specimen from Louisiana; 

 Professor Kirkland has since observed it in Ohio, and Professor Troost in Ten- 

 nessee; and to him am I indebted for the accompanying plate, which was done 

 from life. 



General Remarks. Professor Green was the first naturalist who observed 

 this animal, and he describes it under the appropriate specific name ino^ens, as it 

 is in fact the largest of all our Salamandroidea.
