Remarks. — Kraepelin's Boiga differs from most of the other species 

 of the genus in having a double anal and a scarcely enlarged vertebral 

 scale series; also in the very short posterior cliin-shields, and espe- 

 cialty in the numerous small temporals. 



Habitat. — This species is only known from Formosa, where two 

 specimens were collected by Doctor Warburg, one at Kelung, in the 

 northern part, the other near South Cape. A tliird specimen from 

 Formosa is in the Hongkong Museum, as reported by Doctor Wall.
