These specimens appear to me to belong rather to T. Horsjieldii 

 than to T. nigvo-aVous, as I cannot satisfactorily distinguish, with a 

 lens, any suture above the nostril, and the coloration too of the back 

 and belly is much blended. It is, however, difficult to distinguish 

 the sutures of specimens long preserved in spirit, a has a conspicuous 

 pit below the nostril, as in T. hotJiriorliynchus, but no trace of the small 

 anterior pit described by Giinther. 



T. BOTHRioRHYNCHUs, Giuither. Pinang. 



A groove below the nostril in the suture between the nasal and 

 fronto-nasal, and a smaller one between the rostral and nasal. 



T. STRioLATUs, Pcters. • Bengal. 



T. BRAMiNus, Baud. 



a. many specimens. Bengal, Assam, Sylhet. 



T. TENUIS, Giinther. 



Argyropliis Draminus Daudj ifpud Blyth. 

 a. h. c, three specimens. Bengal. 



These would seem to belong to T. tenuis, Giinther, but are much 

 more slender than his figure in the Cat. Brit. Ind. Reptiles pi. XVI. 

 fig. C. which was from probably a very old specimen. The largest 

 specimens measure 7.5, circumference 0.^0.
