Calamaria flaviceps. 

 Calamaria ScMegelii, Giinth. Colubr. Snak. p. 5 (not Dum. & Bibr.). 



Upper labial shields five ; first pair of lower labials not form- 

 ing a suture together ; an azygos scale between the chin-shields. 

 Head two-thirds as broad as long. Blackish brown, with rings 

 of white dots across the back, each ring corresponding to a white 

 space on the belly; these dots are very obscure, and may en- 

 tirely disappear in old examples. Belly with black cross bands. 

 Head entirely uniform yellow. Ventral shields 153; sub- 

 caudals 20-23. 



Borneo. 



Polemon Barthii. 



We received lately a snake from Old Calabar which agrees so

 Wiss. Berl. 1863,. p. 868). Ventral shields 205, anal divided, 

 subcaudals 18. But, most singularly, the suhcaudals are divided,

Simple subcaudals are justly generally considered as a generic 

 character; but it appears that on the West Coast of Africa,
