upright bars of the yellow ground color between them.

H. nigrocincta, Daud. 

 a. young. 

 The black bands are more symmetrical than on the type, isolating 

 the mle ground color into ellipsoid bands, which arc wider than m the 

 typrcovcring eight scales in the middle or broadest part. On one 

 Jde of our Bp & ecim & en, there are two, on the other only one postocular. 



H. curt a. Shaw. 



a. small specimen. 

 This does not quite agree with the description, as there are four 

 cross bands, but the dedded yellow temporal streak is a sufhcient 

 character to recognize the species by. 



H. cyanocincta, Daud. 

 Hydrus striatus, Cantor. 



a. adult. China. C. J. Bo wring, Esq. 



l' m young. Hidgilli. H. L. Haughton, Esq. 



c. very young. 

 a. has the tail very round and thick, as Giinther says is the case with 



^The^small specimen c. is remarkable for the narrowness of the bands 

 which are narrower than the pale interspaces. It exhibits also the trans- 

 verse frontal streak which becomes obsolete with age. 



H. robusta, Fischer. 



a. fine adult. Hidgilli. H. L. Haughton, Esq. 



I think this must be a variety of H. robusta, though the scales 

 are small and I can find no central tubercle. Scales on neck in 27 rows.
