Described from a specimen from Daijurinzan, collected by Eiji Matsuda 

 in July, 1919. 



Habitat : — Mount Daijurin, Ako (a single specimen). 



Remarks : — The present species is very closely related to Calliophis 

 species in Taiwan Library originally described by J. Hatori in his " Keport 

 on the Formosan Venomous Snakes " (1905, p. 20 ; Giran, Formosa). Ac- 

 cording to Hatori's statement the maxillary of the latter is not provided with 

 solid teeth behind the grooved fang. From the description furnished by his 

 correspondent who has actually examined the same specimen, Van Denburgh 

 also states that " no small teeth could be made out on the right maxilla " 

 (the left was found to be destroyed). There is no doubt, therefore, that the 

 specimen formerly preserved in the Taiwan Library (now lost) belongs to 

 genus Calliophis, although the similarity of the coloration might tempt one 

 to suggest that it may belong to the genus Hemibungarus. 



The coloration of the present species is almost similar to that of the 

 above-mentioned species in having three longitudinal black bands. But the 

 maxillary bones are distinctly provided with solid teeth behind the grooved 

 fangs, two on the right and one on the left. Besides that, there are no 

 lateral white spots along the sides of the body. Such being the case, not 

 only the present species is distinct from Calliophis species, but it belongs to 

 a quite different genus, that is, to Hemibungarus.
