species, andamanensis. The fifth with the scale rows 19 is des- 

 cribed too imperfectly to recognise with certaint}^ but appears to 

 me probably the same form found in Burma in which the scale rows 

 are 19. If my surmise is correct, this specimen, which appears to 

 have been lost, is the true type specimen of hexagonotus , and 

 Stoliczka's name should replace Blyth's as the godfather of the 

 species, hexagonotus having precedence over Theobald's ochracea. 



Under the title hexagonotus IMr. Boulenger appears to me to 

 include two forms which I consider deserve specific recognition. I 

 have records of fourteen specimens of a form from Burma which 

 agree in having 19 scale rows, the ventrals ranging between 221 and 

 245, and the subcaudals 89 to 107. Five of these are in the British 

 INIuseum, the rest are of my own collecting. Two other specimens 

 in the British Museum from Burma collected by Beddome do not 

 conform to this type, but to that known from the Himalayas. In 

 recent papers to the Bombay Natural History Societ}^ I have shown 

 that many of Beddome's records of habitat are open to question, 

 but even supposing that these two specimens have been correctly 

 labelled, they do not vitiate the inferences to be drawn from the 

 series under discussion, as they may have come from hills in the 

 west or north of Burma, the fauna of which closely agrees with that 

 of the Eastern Himalayas. I am of opinion that the form repre- 

 sented by these fourteen specimens all from Burma is a distinct 

 species for which the name hexagonotus should be retained, as it 

 appears probable that the type specimen is that alread}^ referred to 

 from the Andamans by Stoliczka with the scales in 19 rows. 



In addition to these I have examined no less than thirty-nine 

 specimens of a form which inhabits the neighbourhood of Darji- 

 ling, and which is characterised by having 21 scale rows, ventrals 

 ranging from 218 to 252, and subcaudals from 100 to 119. There 

 are three more examples in the British Museum from the same 

 locality which completely agree. Two others in the same Institu- 

 tion from Burma (?) (the query is mine) also agree. This form 

 appears to me a distinct species for which I propose the name 

 stoliczkce, the first references to it having been made by Stoliczka
