TEIID LIZARDS OF THE GENUS CNEMIDOPHORUS 241 



least posterior to the point oi' iuilviny;. In ucltlition, the leddisli 

 element in the general coloration is intensified, the general gronnd 

 color is lighter, and the amount of blue in the ventral coloration is, 

 in general, greater. C Ji y pei'ytJwus caendeus dilt'ers irom (J. hypefy- 

 tlunis danhewiae in that the dorsal ground color above the npper 

 lateral stripe on each side is not abruptly darker tluui the ground 

 color between the tAvo lateral stripes. However, the dorsal bands of 

 cae?mleus are always a trifle darker than the lateral bands. While 

 the dorsal ground color of caeruhus is usually reddish or dark red- 

 dish brown, that of danhelmae is usually grayish or blackish brown. 



Description. — Snout only moderately pointed; nostril anterior to 

 nasal suture; anterior nasal not in contact with second upper labial; 

 supraoculars usually 3; supraocular granules usually not extending 

 forward past the anterior border of the third supraocular; fronto- 

 parietal 1; parietals 3; occipitals in 2 rows, anterior occipitals often 

 4, posterior occipitals numerous, minute ; anterior gulars moderate to 

 large, graded, and usually decidedly larger centrally; posterior 

 gulars small, granulars; scales of mesoptychium often large, these 

 may or may not be largest centrally, often uniform in size ; mesop- 

 tj^chials in about 5 transverse rows. 



Body elongate; ventral plates in 8 longitudinal and 26-33 trans- 

 verse rows ; dorsal granules small ; limbs moderately well developed ; 

 brachials 5-7; antebrachials 3-4; brachials more or less continuous 

 with antebrachials at a point of contact ; postantebrachium with a few 

 slightly enlarged granules; femorals 5-T; tibials 3-4; femoral pores 

 13-20; tail relatively fragile, elongate, tapering; caudal plates large, 

 oblique, and with only moderately strong longitudinal keels laterally. 



Coloration distinctive, relativel}' fixed from young to adult ; ventral 

 and caudal aspect similar to hy perythius and danhelmae ; throat 

 usually not orange colored, often suffused with bluish or grayish; 

 under parts usually light blue; tail often obscurely lined laterally, 

 seldom lined dorsally ; femur striped or unstriped behind, often uni- 

 color above, and never covered with round spots; back with only one 

 dorsal line, tliis usually forked only for a short distance anteriorly; 

 lateral stripes 2 on each side, and of the same intensity as the dorsal 

 line ; ground color of the body reddish or reddish brown, not grayish 

 or blackish, and seldom even moderately dark broAvn; ground color 

 of baclv and sides in general lighter than that of liyperytlirus^ the 

 upper and lower bands not sharply contrasted as in damJieimxie; 

 spots absent from all fields. 



A total of 91 specimens of this subspecies, including the type, 

 have been examined. The data may be summarized as follows: 

 Body, 41-68 mm.; tail, 124-196; total length, 165-259; length of 

 tail as percentage of total length, 72-77; width of head, 6-10; width
