NOTES ON VENOMOUS SNAKES OF THE ISLANDS OF 

 FORMOSA AND LOO CHOO. 



BY 



Masamitsu Oshima 



(Of the Institute of Science, Government of Formosa). 



In the present paper is given the record of collections of venomous 

 snakes, which are contained in the museum of the Institute of Science of 

 the Government of Formosa. The following are the new species in the 

 collections : — 



1. Hetnibungarus matsudai. 

 %. Trimeresurus gracilis. 



It has been my good fortune during a visit to Loo Choo Islands in the year 

 1915 to be able to examine a fine herpetological collection in the museum of 

 Nago Agricultural School and to carry the duplicates to Formosa for the 

 sake of further study. For this privilege, I wish to express my hearty thanks 

 to the authorities of that School, especially to Mr. Tetsuo Miyagusku, the 

 head Professor. I also express my special obligation to Mr. Eiji Matsuda of 

 Ako Public School for services in collecting rare specimens. I am also under 

 special obligation to Dr. Leonhard Stejneger of the United States National 

 Museum and to Dr. Malcom Smith of English Legation at Bankok, Siam, 

 in determining the specific names of doubtful specimens. 



In the systematic arrangement, I have depended entirely on the Herpe- 

 tology of Japan and Adjacent Territory, by Dr. Leonhard Stejneger. The 

 colored plate of Trimeresurus gramineus is the work of I. Sakuma of the 

 Imperial University Tokyo ; the others were prepared by myself.
