46 Catalogue of Reptiles. 



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

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



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

 mark of separation from both Ablabes and Calamama, and adopt conse- 

 quently Giinther's genus. (Brit. Mus. Cal. Colubrine Snakes, page, dU.) 



FAMILY OLIGODONTIA. 



OLIGODON, Boie.

0. brevicauda, Giinth. Anamallies. 



SIMOTES, DUMERIL ET BlBRON. 



S. bicatenatus, Giinth. 



a. five adults. 



b. two ditto. 



c. two ditto. Pegu. W. Theobald, 



Junior, Esq. 



d. one ditto. Ditto. Ditto. 



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

 fering from 8. punctulatus. - As, however, the coloration is much like 

 var. y of 8. punctulatus, I think they may belong to the allied species 

 G anther names, without fully describing, 8. Labuanensis, Gunth., which 

 has a small lower ante-ocular. 



e. two young. Jessore, Mergui. 



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

 8. bicatenatus from Mergui. The other probably belongs to a variety, 

 perhaps to 8. aMwvmter.
