REPORT OF NATIONAL MUSEUM, 1898. 



three large ones with eight to ten smaller ones on the sides and in front. 

 The hind leg a little short, the longest toe when extended not reaching 

 the meatns auditorius by the diameter of the latter. 



Measurements. — Total length, 300 mm. ; length to angle of mandible, 

 25 mm.; length to collar, 32 mm; leugth to axilla, 42 mm.; length to 

 vent, 100 mm. ; length of fore limb, 30 mm. ; length of fore foot, 13 mm. ; 

 length of hind leg, 64 mm. ; of hind foot, 35 mm. 



The color is uniform olivaceous above and below, with the following- 

 black marks: There are three rows of black spots on each side of the 

 middle line above; the superior small, subquadrate, the second larger 

 and transverse, the inferior forming short crossbars. The superior row 

 extends from the interscapular region to the middle of the leugth of the 

 back; the second row extends further, and the inferior row extends 

 nearly to the groin. Limbs, head, belly, and tail unspotted. 



But two specimens are known to me. In Cat. No. 3033 the black spots 

 are smaller and are restricted to the anterior fourth of the length of 

 the body, being most distinct in front of the scapular region. Here 

 traces of the original six stripes are visible between the spots. 



This form has various peculiarities which entitle it to be regarded as 

 a subspecies, and possibly as a species. 



It is possible that it may be demonstrated that C. sericeus is estab- 

 lished on a female of this species with abnormally reduced frontoparie- 

 tal plates. The coloration is much like that of specimen Cat. No. 3033, 



Cnemidophorus gttlaris semlfasciatus Cope. 



CNEMIDOPHORUS LABIALIS Stejneger. 

 Cneviidophorits lahialis Ste.jneger, Proc. U. S. Nat. Mns., XII, 1889, p. 643. 

 The following description is copied from Stejneger: 



Nasal iu contact with second supralabial; postnasal and first supralabial not in 

 contact ; two large preanals, the largest behind ; dorsal scales equal ; nostril anterior 

 to nasal suture; eight longitudinal rows of ventral plates; femoral pores twelve to 

 thirteen ; fronto-parietuLs distinct; supraoculars four; caudal scales slightly oblique. 



Nostril anterior to nasal suture; three parietals ; four supraoculars; seven supra- 

 ciliares; a freuo-orbital ; two fronto-parietals; scales on middle of eyelid slightly 

 enlarged, hexagonal; nasal in contact with second upjier labial, postnasal and 

 second upper labial being separated; posterior gular scales small, abruptly sepa- 

 rated from the anterior, the line of demarkation between them being emphasized 

 by the two rows nearest the latter being markedly smaller than the rest of the 

 posterior ones; plates of the collar rather large, in several rows, the marginal larg- 

 est; dorsal granules smooth, rather large; ventral plates in eight longitudinal and 

 thirty-one transverse rows. Two large preanals, wider tlian high, the posterior 

 plate being widest. Three rows of brachials of nearly the same size; antebrachials
