abdomen is white, blotclied not very deeply with black two or three 

 scales wide, and a continnation of the dark shade in the prolongation 

 of the lateral rhomboids. The blotches of the opposite sides are some- 

 times confluent and sometimes alternate. In one specimen the black 

 patches are rather wider, extending nearly to the abdomen. Head less 

 blotched with yellow than 0. (/'hoylii. Differs from O. g. boylii in having 

 the light intervals in the form of spots in the centers of dark scales, 

 instead of covering the whoUi space. The lateral blotches are alternate 

 with those of the back, not continuous and opposite. The blotches are 

 more numerous.

This form approaches near to those of the 0. g. sayi with transverse 

 rows of spots on the median dorsal region. The head and nape are 

 much less spotted than in the latter, and I have not found any varia- 

 tion in the different scale formulas of the two.

Black, with upwards of thirty broad ivory-white transverse bands, 

 widening on the sides. Dorsal rows of scales twenty-three. 



Vertical plate distinctly pentagonal, longer than broad ; more elonga- 

 ted tlian in 0. ,sai/i. Sides nearly parallel, a little shorter than the 

 occipital plates. The sides of the head as in 0. sayi. Dorsal rows 

 twenty-three, the scales rather more elongated than in O. sayi. Outer 

 row a little larger, all the rest nearly equal. Back and sides black, 

 crossed by about thirty-seven ivory-white bands, the thirtieth opposite 

 the anus. On the vertebral region these bands are about one and a 

 half scales wide, with the margins parallel to about the seventh outer
