'' Tlie restriction of this genus to .snakes having the dorsal rows in even 

 number does not appear to me justifiable. The type of Spilotes Wagler is 

 .S'. pullatus, which species alone, Boalensrer admits in the genus. It, how- 

 ever, has the scales frequently in an odd number ; two specimens from 

 Trinidad, formerly in the Zoiilogical Garden, had 15 and 17 rows respectively 

 iProc. Acad. Phila., 1893, 4^2).
