Description, 



a The specimen in question (No. 1483) was examined by me in 1898; for the per- 

 mission to do so thanks are due to the director, Doctor Jentink. It was labeled as 

 stated above, and the count of ventrals and subcaudals gave respectively 341 and 51 

 scutes. These figures, however, agree only with the third specimen mentioned by Schle- 

 gel (Phys. Serp., II, p. 504), who states that this is the one collected by Buerger. 

 Whatever error may have crept in, there can be but little doubt that the specimen 

 was collected practically in the same waters as the others.
