9. Callisaurus splendidus, new species 



Type.— A. M. N. H. No. 5372, tf. Collector, C. H. Townsend, Albatross 

 Expedition, April 10, 1911. 



Pakatypes.— A. M. N. H. Nos. 5338, 5342, 5373-5375, 5396. 



Type Locality. — Angel de la Gnarda, Gulf of California, Lower California, 

 Mexico. 



Synonyms. — Callisaurus ventralis, Townsend, 1890,Proc. U. S. Nat.Mus., VIII, 

 p. 144; Callisaurus draconoides ventralis (part), Cope, 1898 (1900), Rept. U. S. Nat. 

 Mus.,p. 273. 



Diagnosis. — Size medium, adults averaging between 150 and 160 mm., total 

 length, probably seldom reaching 170. Hind leg in male somewhat shorter than 

 head and body to anus, when folded forward along body little exceeding end of 

 muzzle. Tail in male longer than head and body, never one and one-half times as 

 long. Femoral pores 10-14, averaging 12 (8 specimens). Coloration light to dark, 

 more or less vividly red over the whole dorsal surface as well as on gular region and 

 anteroventral aspect of humerus. The 2 black bands on the lateroventral blue area 

 neither large nor vivid; their position oblique forward with reference to lateral fold, 

 the posterior of the two at its inferior end with tendency to extension backward toward 

 the groin. Tail conspicuously banded below and above with black. 



Measurements op the Type. — Total length, 150 mm.; head and body to 

 anus, 65 mm.; tail length, 85; tip of muzzle to posterior margin of ear, 15, to gular 

 fold, 21; head width, 12.5; hind leg, 64; hind foot, 30; base of 5th to end of 4th toe, 

 24.5. 



10. Sceloporus lineatulus, new Species 



Type.— A. M. N. H. No. 5478, o 71 . Collector, C. H. Townsend, Albatross 

 Expedition, May 16, 1911. 



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



Diagnosis. — A robust species of medium size (length of head and body of adult 

 male, 85 mm.), especially bristling with large, long-pointed but not spinous scales; 

 4-6 preauriculars in oblique row, relatively long and pointed, overlapping at bases; 

 dorsal scales (7 straight longitudinal rows) much larger than ventrals; laterals 

 crowded in oblique rows, graduated in size to meet ventrals, the shape changing 

 through intermediate stages from angular, long-pointed, weakly denticulate scales 

 to the rounded ventrals with their 2-4 equal points or scallops; rump and proximal 

 caudals equal to dorsals; dorsals about 28 from interparietal to base of tail, 5 in head 

 length (muzzle to interparietal) ; distance from base of 5th toe to end of 4th equal to 

 length from tip of muzzle to anterior border of ear; femoral pores, 20. Coloration of 

 adult male rufous dorsally, blue lateroventrally verging into green above, blue on 

 chest between arms, and on chin ; sides prominently marked from above arm to groin 

 with about 11 longitudinal parallel brown lines following the direction of the scales; 

 posterior gular region black, also black more or less as follows: on ventral arm, 

 breast, median abdominal area, groin, ventral femur. 



Measurements of the type. — Total length, 199 mm. +; head and body to 

 anus, 85; tail length, 114 + (reproduced); tip of muzzle to posterior border of inter- 

 parietal, 21, to posterior border of ear, 25, to base of throat, 25; greatest head width, 

 23, width at posterior orbital angle, 20, at anterior orbital angle, 13.5; hind leg, 61; 

 base of 5th to end of 4th toe, 24.
