1891 .] W. L. Sclater — Notes on the Snakes in the Indian Museum. 231 



To the 264 snakes given in Mr. Boulenger's work I have now eleven 

 to add, of which five are new, and described here for the first time and 

 six are exotic species now recorded from the Indian Empire for the first 

 time, so that the total number of Indian Snakes is now raised to 275. 



The Indian Museum possesses a fair number of types, but unfor- 

 tunately several which I believe should be here .are no longer to be found 

 in the collection, such is the case with Typhlops andamanensis, Stoliczka, 

 Calamaria catenata, Blyth, and several others. 



The following is a list of the species, twenty-one in number, of which 

 the types ai^e still in the Museum. 



Typhlops theobaldianuSfSto]. Goluher prasinus, Bly« 



TracMsehium fuscum, (Ely.) Pseudoxenodon macrops, (Bly.) 



5, tenuiceps, (Bly.) Tropidonotus platyceps, Bly. 



Blythia reticulata, (Bly.) ,, nigrocinctus, Bly. 



Lycodon gammiei, (Blanf.) Dipsas multifasciatus, Bly. 



Hydrophobus davisoni, (Blanf.) Hypsirhina blanf ordi, Boul.* 



Pseudocyclophis bicolor, (Bly.) Distira tuherculata, (Anders.) 



Ablabes scriptus, Theob. Amblycephalus modestus, (Theob.) 



,, nicobarensis, Stol. ,, macidarius, (Bly.) 



Zamenis ladaceensis, Anders. Trimeresurus cantoris, Bly. 



Zaocys nigromarginatus, (Bly.) 



To these must be added the types of the five new species described 

 below. 



Ablabes stoliczkae. Tropidonotus pealii. 



Simotes woodmasoni. Tropidonotus nicobaricus. 



Zaoccys tenasserimensis. 



There are also in the Indian Museum the types of the following 

 species found on che borders of the Indian Empire but not yet recorded 

 from within its limits. 



Typhlops per sicus, Blanf. Pseudocyclophis persicus, (Anders.) 



Calamaria stalknechti, Stol. Dipsas rhinopovia, Blanf. 



The total number of types therefore in the Indian Museum is thirty. 

 It is only due to Mr. Boulenger to add that it is entirely owing to 

 his useful and excellent manual on Indian Reptiles in the Indian Fauna 

 series that I have been able to work out and rearrange the Snakes in the 

 Indian Museum, so much has been done since Giinther's Reptiles of 

 British India appeared and that scattered over so many various separate 

 works and periodicals. 



The Snakes in the Museum are now arranged in accordance with 



* Originally cTesoribecl by Blanford as H, macxdosa, name changed by Boulenger.
