thickness as the posterior part of the head ; the scales upon the tail, with the

 body at middle 14 lines.

Spec. char. Head flattened ; skin granular ; back above, in some speci- 

 mens, presenting scattered yellow spots upon the back and sides ; abdomen 

 orange, with numerous black spots, resembling those of Triton cristatus; 

 chin and throat orange ; black spotted ; under part of tail orange ; tail long, 

 much compressed. 



Dimensions. Length of head six lines ; greatest breadth 6 lines ; length of 

 neck and body 1 inch 9 lines ; of tail 2 inches 8J lines ; total length 4 inches 

 11 lines. 



Habitat. Specimens marked No. 5, found in the Paddyfields at the 

 Amakarima Isle, Loo-Choo, April, 1855, by Mr. Squires and Mr. Macomb. 

 Other specimens, marked 53 in the Catalogue, from Ralousima. Those from 

 this place, the northern half of Ousima proper, are yellow beneath, without 

 the large black spots upon the abdomen. 



Gen. remarks. This species resembles much Triton cristatus of Europe, 

 but wants the white, minute points upon the sides and chin, and the tail is 

 much longer. According to Prof. Schlegel, the osteology of the head is also 

 different, and the number of vertebrae less, there being sixteen in Triton 

 cristatus, and but fourteen in the present species. We have compared 

 these specimens with one from Japan, due to the generosity of the Adminis- 

 tration of the Garden of Plants, and find no difference except that the black 

 spots upon the abdomen are not so numerous in the Japanese specimen, and 

 the tail is shorter and less compressed at its root. The coloration above, in 

 the Japanese specimen, is brown ; in those from Amakarima Island, a deep 

 black. We had proposed for this dark colored Triton, with its narrow and 

 much compressed tail, the name ensicauda, but, without a greater number 

 of specimens for comparison, we are unwilling, at present, to consider it a dis- 

 tinct species.
