the same faunal zone as Plumosas. This snake was Boulenger's only speci- 

 men of tigris. It was small (380 mm.) and has the following scale count: 

 V 181, C 46, Sc 25. I strongly suspect that it is the present species. The 

 caudal count is far too high for tigris. Unfortunately it is impossible to 

 determine how much of the description in the Catalogue of Snakes is drawn 

 from this specimen and how much from literature. Still a comparison with 

 the description above shows many points of resemblance and a few of dis- 

 cord other than the two less scale rows and the slight ventral and caudal vari- 

 ations. Also the following statements are not in accord with the state of 

 affairs in tigris. " Snout with distinct canthus, " " a large scale on each side 

 between the internasal and the supraocular," "three series of scales between 

 the eyes and the labials," "dark-edged spots."
