ceeding- from the parietal and superciliary scales. At the scapular 

 region the black spaces are broken iuto square spots, forming three 

 longitudinal series, one median. The other black spaces form trans- 

 verse bars on the sides, and they are sometimes united above, forming 

 inverted Vs. They tend to fuse with the dorsal series posteriorly, and 

 in one of the types this is completed, thus forming irregular black 

 cross bars. The superior surfaces of both limbs are black, with large 

 yellow spots, Superior dark band extending as shades on the supra- 

 orbital plates. A pale light stripe from orbit over meatus auditorius. 

 Gular region unspotted. Black spots covering, or on the base onl}^ of, 

 some of the lateral abdominal scuta. Tail with two or three rows of 

 dark spots on an olive ground above; below unspotted. Posterior face 

 of femur with yellow spots separated by vertical dark lines. 



But two specimens of this form are contained in the U. S. National 

 Museum, the original types of Baird and Girard. In one of these there 

 are six infralabial scuta on both sides, and in the other there are but 

 five on one side. On the other side there are spaces for six, but two 

 are fused into one, so that I believe that six is the normal number for 

 this subspecies as it is for the others. Two other specimens were 

 obtained by Mr. W. L. Black, of the geological survey of Texas, at 

 Tule Canyon on the Staked Plain. They differ only from the presence 

 of a median dorsal zigzag light stripe. 



Baird's figure represents this handsome form very well.

 The following description is by Van Denburgh : 



Adnlt male (Type No. 1861, Leland Stanford .Tiinior University Mnsenm, collected 

 by J. M. Stowell between San Rafael and Ensenada, Lower California, .Tune 8, 1893). 

 Nostril anterior to uasal sutnre; 3 parietals, 2 frontoparietals, 1 8n])raornlars, (5 

 siiperciliaries; nasal not reachini^ second superior labial ; postnasal in contact with 

 both first and second superior labials. Posterior ijjnlar scales rather larg'e, abruptly 

 separated from the verj' large and convex anterior gulars. ^ Plates of collar very 

 large, but smaller along its edge. Ventral plates in eight longitudinal rows. Back, 

 neck, and upper surfaces of limbs covered with very small, smooth, convex gran- 

 nies. Five rows of brachial plates ; three rows of antebrachials ; no post-antebrachial 

 plates. Femoral rows in seven rows. Twenty and twenty-two femoral pores. Scales 

 on tail large, oblique, slightly pointed, and with strong diagonal keels. 



Color above yellowish-brown posteriorly, becoming grayish toward head, paler 

 on sides, with nine longitudinal rows of very irregular black spots. Upper surface 

 of limbs similarly marked. Plack markings on sides of head and neck and on gular 

 region large and well defined. Lower surfaces creamy white, maculated with black.
