(4) D. andamanensis , sp. nov. 



Characterised by 21 scale rows, ventrals 259 to 267, subcau- 

 dals 118 to 133. Habitat — Andamans. 



From the above tabulated specimens it appears to me that 

 under the title ceylonensis at least four distinct forms have been 

 confused, all of which I consider should rank as species rather than 

 varieties of a single species. P'or the first of these I would reserve 

 the title ceylonensis ^ for Giinther's type specimen with scales 19 

 ventrals 220, subcaudals 108, habitat Ceylon, clearly is one of this 

 form. 



For the second beddomei seems to me appropriate, since most of 

 the known specimens are of Colonel Beddome's collecting.
