Notes on a Collection of Snakes from Japan and the Loo Choo Islands. By Captain F. W a l l , C.M.Z.S., Indian Medical Service. I am indebted to Mr. Alan Owston, of Yokohama, for the opportunity of examining a large number of Snakes collected by him in Japan and the Loo Choo Islands. Of a total of 513 specimens, 461 are Land Snakes ; and the special interest of the collection lies in the extensive and representative area in which the specimens have been captured, for besides a large number obtained from Japan itself and many from all the important islands of the Loo Choo Group, examples have been obtained from the two islands, Tanega and Yaku, interposed between Japan and the Northern Loo Choos. They are distributed as follows : - [Received August 28, 1905.] Y e z o . 1. Ancistrodon blomhoffii. (1 ) 1 H o n d o . 1. Tropidonotus vibakari. (14) 1 (53) ( 1) 2 . ,, tigrinus. 3.
