REPORT OF NATIONAL MUSEUM, 1898. 



mens of a second lateral series on each side. There is no indication of 

 the ten lateral light stripes on the side, nor of the pale stripe along the 

 back separating the dorsal blotches. The sides and back are more 

 regularly spotted with whitish. The jaws are banded transversely 

 with bluish, which passes obliquely backward on the chin. 



The most striking differences from its allies seen is the much more 

 backward position of the two indigo-blue blotches and their inferior 

 situation on the sides and in the whitish of the belly, and not on the 

 sides of the body, partly in the brownish. They are also completely 

 enveloped in the blue patch instead of having only an occasional slight 

 suffusion of the same. They are almost entirely, instead of very 

 slightly, visible from below.

 HOLBBOOKIA MACULATA FLAVILENTA COPE. 



Lake Valley, New Mexico. 



Collection of E. D. Cope. 



This subspecies differs from the typical form in having larger preuasal 

 scales separated l)y only two flat scales in front, instead of four tuber- 

 cular ones, and in having only four flat scales between the nostrils 

 above, instead of six tubercular ones, and in having the scales of the 

 front flatter. The spots are obscure or entirely wanting; when present 

 they are more numerous than in the var. maculata, there being eight 

 between axilla and groin, instead of six. The sides and dorsal lateral 

 regions are thickly marked with small yellow spots. 



This form was established on two specimens from Lake Valley, in 

 southern New Mexico. Dr. Stejneger has since recorded it from south- 

 ern and western Arizona.
