1919| Dickerson, Diagnoses of New Species and a New Genus of Lizards 471 



Measurements of the Type. — Total length, 149 mm.; head and body to anus, 

 54; tail length, 95; tip of muzzle to posterior margin of ear, 14, to gular fold, 18; 

 head width, 11 ; hind leg, 40; hind foot, 20. 



15. Uta parva, new species 



Type.— A. M. N. H. No. 5428, <?. Collector, C. H. Townsend, Albatross Expedi- 

 tion, March 13, 1911 



Paratypes.— A. M. N. H. Nos. 5427 9, 5429, 5431-5433. 



Type Locality. — San Bartolome Bay, Lower California, Mexico. 



Diagnosis. — A very small, fine and smooth-scaled = Uta of the Stansburiana 

 group, with tail twice length of head and body. Dorsal scales small, keeled, somewhat 

 tubercular, well differentiated from lateral granules; dorsals average about 100 

 between interparietal and base of tail, very much smaller than brachials, 13-15 rows 

 from median line to lateral granules; brachials more or less weakly keeled, about 

 equal to scales on rump and very much more pointed. Head brown, dorsal color 

 pattern an all-over arrangement of small blue spots in male, in female transverse 

 series of long and wavy dark lines bordered behind with light, sometimes connected 

 with a series of white transverse lines on the lateroventral blue surface; gular region 

 anterior to collar deep blue in male; postaxillary spot of medium size, largely con- 

 cealed by adpressed elbow. 



Measurements of the Type. — Total length, 101 mm. +; head and body to 

 anus, 43; tail length, 58 + (reproduced, length of tail of No. 5431 of which head 

 and body length is 44, 80) ; tip of muzzle to posterior border of ear, 11.5, to gular fold, 

 14.5; head width, 9.5; hind leg, 42; hind foot, 17. 



16. Uta squamata, 1 new species 



Type.— A. M. N. H. No. 5424, &. Collector, C. H. Townsend, Albatross 

 Expedition, May 16, 1911. 



Paratypes.— A. M. N. H. Nos. 5421-5423, 5425-5426. 



Type Locality. — Santa Catalina Island, Gulf of California, Mexico. 



Diagnosis. — A small lizard not exceeding 135 mm., with the general appearance 

 of the members of the Uta stansburiana group, but distinguished at once by the uni- 

 formity and large size of the imbricated dorsal scales (everywhere distinctly separable 

 from the lateral granules, about equal to the brachials, 10-11 from median line to lateral 

 granules), coupled with still greater coarseness of the femorals and tibials, and of the 

 caudals on thickest part of the tail. Dorsals 72-76 from the interparietal to the base 

 of the tail, 63 ventrals from denticulated collar to anus; femoral pores 13-16, averag- 

 ing 15. General coloration olivaceous, males with the typical adult Uta all-over 

 pattern of fine dots; ventral surfaces everywhere blue, no postaxillary spot but wide 

 ventrolateral bluish black band from axilla to groin. 



Measurements of the Type. — Total length, 135 mm.; head and body to anus, 

 52; tail length, 83; tip of muzzle to posterior margin of ear, 14, to denticulated gular 

 fold, 19; head width, 11.5; hind leg, 39; hind foot, 20. 



'With reference to the imbricated dorsal scales of unusually large size and the coarseness of 

 femorals and tibials. ^*\
