46 Catalogue of Heptiles. 



a. Two adults and one young. Darjiling. W.T.Blanford, Esq. 

 5. Two specimens (one injured.) Rangoon. (?) Purchased. 



I think the peculiarity of the single posterior frontal a good generic 

 mark of separation from both Ahlahes and Calamaria, and adopt conse- 

 quently Giinther's genus. (Brit. Mus. Gal. Coluhrine Snakes, page, 30.)

d. one ditto. Ditto. Ditto. 



These specimens have the lower ante-ocular very small, thereby dif- 

 fering from S. imnctulatus. As, however, the coloration is much like 

 var. y of S. inmctulahis, I think they may belong to the allied species 

 Giinther names, without fully describing, S. Lahuanensis, Giinth., which 

 has a small lower ante-ocular. 



e. two young. Jessore, Mergui. 



One specimen has a minute lower ante-ocular, and is doubtless, 

 S. hicatenatiis from Morgui. The other jjroljably belongs to a variety, 

 perhaps to IS. atblvcider.
