cies seems to need a more complete diagnosis, I will give a do- 

 ser description of these specimens. 



Frontonasal as long as broad, or a little longer than broad, 

 forming a suture with the rostral (in specimens in the British 

 Museum the frontonasal is separated from the rostral) and 

 widely separated from the f rontal; rostral rectangular, consi- 

 derably broader than high, prsefrontals large, with a long me- 

 dian suture; f rontal hexagotial, as long or not quite as long as 

 its distance to the tip of the snout; parietals large, in the one 

 specimen a verv small interparietal, which is lacking in the 

 other; four labials anterior to the subocular;^ the eye encircled 

 by a series of small scales, 11 — 13 below and 5 — 7 above the 

 orbit; four surpra-oculars, the two middle largest; a postnasal 

 and a large loreal, touching the upper anterior corner of the 

 orbit; at the lower anterior corner there are one or two small 

 prseoculars; between the eye and the earopening four tempo- 

 rals, a large one above and 3 smaller below; a long narrow scale 

 borders the anterior margin of the ear, projecting över the large 

 opening like a kind of lid. 



Dorsal scales strongly keeled, in 24 or 26 longitudinal and 

 42 — 45 transverse series from occiput to base of tail; the scales 

 on the sides of the body broader than those on the back; ven- 

 .trals in 8 longitudinal rows; 25 or 26 femoral pores on each side 

 (22 in a specimen in British Museum). Tail cylindrical, except 

 the base, which is depressed with the upper surface considerably 

 broader than the lower, its vertical section being nearly tri- 

 angulär; the tail more than twice as long as the head and body. 



Dark olive brown above and on the sides, the back dotted 

 with yellow, a broad light band on each side, extending from 

 the occiput out on the base of the tail; the head uniform light 

 brown; under surfaces dirt}^ white; in one specimen the chin 

 and throat dotted with black.
