316 REPORT OF NATIONAL MUSEUM, 1898. 



along their sumiuit, esi)ecially oji the dorsal fokls, distant about the 

 width of the head, where the larger scales occur at intervals. The 

 scales on the tibial joint are larger and more angulated than in the 

 other. The hind feet are short, not one- third the head and body; the 

 hind feet are shorter, the fingers considerably longer than in stanshu- 

 riana. The head is broad; the width equal to the distance from snout 

 to middle of occipital, the free portion of long hind toe a little less. 



The tail is a little longer than the body, or possibly longer, as it has 

 been renewed ; depressed or trigonal at base, then cylindrical or even 

 a little compressed. The femoral pores are about eleven in number. 



The scales on the chin are quite small and rounded or paved, 

 decidedly smaller than the imbricated rhomboidal scales of the space 

 between the gular folds. 



The folds of skin, where they can be made out, apj^ear to run in 

 the following manner: The longest starts in a line with the edge of the 

 head above and a short distance behind the head, running back to the 

 upper edge of the insertion of the thigh. This is crowned at intervals 

 by large scales. The second begins on the lower j^art of the sides, just 

 back of the axilla, and after rising a little runs back nearly to the 

 groin parallel with the upper fold. This likewise shows occasional 

 larger scales. The fold crossing the throat and shoulders anteriorly 

 is continued a little obliquely backward to the upper or dorsal fold. 

 Anterior to this, another fold begins on either side the throat and 

 extends half way round the side of the neck, where it covers the gular 

 cavity seen here and in Sceloporus. Here it meets a short fold running 

 downwards from the upper border of the ear (continued behind to 

 the first transverse fold), and from this point of intersection there pro- 

 ceed two folds across to the upper or dorsal one, united below. A sec- 

 ond short fold runs from the lower edge of the ear back to the second 

 transverse fold. 



This species is of a brownish gray above; each side of the back with 

 a series of transverse narrow bars of black, with a light grayish areola 

 and varying in shape, sometimes a meniscus, sometimes bifurcating. 

 There are usually two short longitudinal stripes on the nape. From 

 the shoulder usually runs a dark line perpendicularly to the back, and 

 sending a short branch abruptly forward at a right angle and in line 

 with the ventral stripes. The under parts are white, in the male the 

 chin is greenish, and on each side the belly, nearly meeting centrally, 

 is an elongated x^atch of light greenish or bluish as in Sceloporus. 



Variety linearis. — Among the specimens before me are several (as Cat. 

 No. 2759), which, with the general characters of Uta ornata, have instead 

 of the transverse bands a trace of four dorsal black lines, interrupted 

 at irregular intervals, and thus broken up into sections from an eighth 

 of an inch to an inch. One of these on either side borders the large 

 scales, the other runs along the raised lateral fold. There is the usual 

 blackish bar in front of the shoulder forming a kind of interrupted 

 collar. There are a few light spots on the side.
