former region is crossed in the typical specimen by thirty-six blackish- 

 brown crossbars, which are wide and close together on the median 

 dorsal region, and tapering-, and therefore separated on the sides. The 

 dorsal parts of the spots nnite and form two wide longitudinal bands on 

 the anterior fifth of the length. A pale brown band passes from the 

 superciliary phite to the side of the neck, leaving a dark j^ostorbital band 

 below. All the plates of the lips and throat are yellow, and have nar- 

 row black borders. On the yellow of the belly there are black spots 

 on the gastrosteges which incline to fuse transversely, leaving a i)art 

 of the ground visible in the middle. Anteriorly this arrangement 

 assumes the form of two longitudinal black bands, which are well de- 

 fined on the anterior fourth of the length, leaving a yellow band between 

 and one on the outer side of tliem.

Labials, eight to ten; oculars, 1-3; 

 temporals, 1-3. Frontal narrow, not 

 widened anteriorly; parietals rather 

 wide. First row of scales keeled. Gas-
