and along the middle line, with a series of eight 'herring- 

 bone' crossbars of dusky, growing pale posteriorly and in- 

 cluding a light spot on the middle line 5 the six anterior 

 cross-bars are bordered behind by a narrow black line, and 

 all, both in front and behind, by a whitish line which is 

 broader behind than in front ; on the sides several rows of 

 indistinct pale spots, many of them bordered anteriorly by 

 dusky ^ a narrow dusky line across the head between the eyes; 

 an indistinct dusky line from nostrils through eyes to 

 above ear; legs and tail with indistinct and irregular cross- 

 bands of a lighter shade than the ground color; underside 

 whitish, with an elongated patch of emerald green on the 

 flanks and a more yellowish one on the middle of the throat.

Remarks. Uta ornata and Uta symmetrica were long 

 regarded as distinct species, but when larger series of speci- 

 mens were collected it was found that none of the supposed 

 differences between them were more than individual varia- 

 tions (see Van Denburgh and Slevin 1911, and Strecker 

 .1.911). There seems to be no real difference in the regu- 

 larity of the rows of large dorsal scales, the length of the 

 hind leg, coloration, or habitat. 



Schmidt recently has pointed out that in Texan speci- 

 mens enlarged tubercles between the dorsolateral and lat- 

 eral lines are absent or feebly developed, while in those from 

 Arizona oblique series of tubercles in this region are evi- 

 dent. This difference is shown also by my specimens, and
