than the posterior; a pair of small transverse occipitals ; ocular 
small, eye distinguishable ; three upper labials, third largest ; mental 
small, followed by a larger chin-shield ; three lower labials, first two 
very small, third very large. Two hundred and thirty-four annuli 
on the body and eighteen on the tail; on the middle of the body an 
annulus comprises thirty segments, sixtcen above and fourteen below 
the lateral line ; the dorsal segments longer than broad ; the ventrals 
larger, the two median series much broader than long throughout 
the length of the body. Three pairs of pectoral shields, of which 
the median is broadest and preceded by a pair of rhombic shields. 
Lateral line distinct. Two large pairs of anal segments, with a

the anterior ; a pair of small occipitals ; ocular very small, eye in-
