shields covering the head, the anterior a little shorter, but broader, 

 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, sixteen 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 

 tendency to unite into one pair ; on each side a minute additional 

 segment. A prajanal pore on each side. Brownish above, whitish 

 beneath ; cephalic scutes yellow.

Agrees with M. scalper in the pholidosis of the head and the pec- 

 toral shields, but differs in the much larger segments of the body, 

 of which there are only ten dorsal and eight ventral rows. Two

 tail. Six anal segments. A prseanal pore on each side.

A small subtrapezoid rostral separating the nasals ; two large 

 shields on the head, the posterior narrower and not half as long as 

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

 visible ; three upper labials, third very large ; mental small, trape- 

 zoid, followed by a much larger hexagonal chin-shield bordered on 

 each side by a narrower one : three lower labials, third very large. 

 One hundred and ninety-nine annuli on the body and ten on the 

 tail. Pectoral shields large, six, the median pair longest, narrowed 

 anteriorly, the second pair L-shaped. Lateral line distinct. Two
