Uta elegans, sp. nov. 



Description. — Dorsal scales smaller than ventral, earinated. Su- 

 praorbitals five, with one or two very much smaller ones anteriorly. 

 The rows o^ large submental scales terminate in two or three sharply- 

 pointed ones at anterior order of auditory aperture. Femoral pores 

 fifteen. A sharp ridge of three scales runs irom anterior margin of 

 orbit to nostril. Gular fold bordered with large scales. Color greenish 

 blue, light spotted. Seven oblong transverse bhick blotches from nape 

 of neck to thighs. Under part of head indigo blue, with bright yellow 

 markings near the jaws. Between auditor;^ aperture and posterior to 

 the axilla, an irregular series of cadmium yellow spots; posterior to 

 this an indigo-blue blotch bordered with yellow above. Abdomen light 

 indigo blue; tail unspotted, but with indication of dark bands on upper 

 surface. This species in life must be very brilliant in coloration, re- 

 sembling somewhat Uta schotti. 



Sceloporus rufidorsum, sp. nov. 



This beautiful and characteristic species was discovered at San Quen- 

 tin Bay, California, by Mr. L. Belding, who has forwarded other speci- 

 mens of it from La Paz and Cerros Island. 



Description. — Scales of dorsal region strongly earinated, as large 

 as those of 8. clarJci zoste romus, in twelve rows between insertion of 

 upper extremites. Abdominal scales smaller than labials. Cephalic 

 shields not earinated, but slightly tuberculated. Prefrontal broader 

 than long. Superoculars in three series, not in immediate contact with 

 the superciliary series. Abdominal scales finely denticulate. Scale of 

 base of tail larger than upon any other part of the body. Femoral pores 



specimens gradually fades towards the lateral region, and which in others 

 is confined to three scales in width. Posterior to the upper border of the 

 auditory orifice a light yellow line is seen, which extends seven scales 

 backwards, and turns downwards at a right angle, continuing until the 

 shoulder is reached; anterior to this, and in the angular space thus 

 formed, is a patch of deep indigo blue. Sides of body and abdomen 

 same color, many of the scales being spotted with malachite green. 

 This color terminates abruptly at the line of femoral pores. Tail bluish 

 brown above, bluish white beneath. This species is to be compared 

 with >S'. clarJci zosteromns, from which it differs principally in coloration.
