developed ro^y between the long .suborbital scale aud tlie superior 

 labials and a few granular scales above it in two of the specimens, 

 instead of the two well-developed rows in the U. scGparia. The end 

 scales of the suborbital series are somewhat variable in number and 

 character, but there is usually but one keeled scale posterior to the 

 long median scale in place of the three of the TJ. scoparia. The feet are 

 of about the same length as in the U. scoparia, measuring one-third the 

 length of the head and body, or less; and they are thus distinctly 

 shorter than in the U. notata. The claws of the manus are not exca- 

 vated nearly so far proximad nor so deeply as in the U. scoparia, nor 

 are thej^ twisted so that the edges are directed outward, as in the latter. 

 In coloration this species differs widely from the U. scoparia. On the

gular region, instead of the two conspicuous transverse black crescents, 

 there are longitudinal narrow blackish lines. There are six or seven 

 black spots on the distal half of the under side of the tail, of which 

 the anterior are small and transverse, the i^osterior longer and covering 

 the entire inferior surface. The black lateral spot is large and is entirely 

 inferior; its outline varies from subcircular to subquadrate. The color 

 of the superior surfaces differs from that of the XL scoparia, in that the 

 black ground remains in the form of longitudinal lines, of which there 

 are ten or eleven. The interspaces are broken up into discoidal spaces 

 of light yellowish-brown, their isolation being most complete near the 

 middle line. Each discoidal space has a rusty or rufous central spot 

 in place of the black spot of the TJ. scoparia, and it is therefore less dis-
