KEPORT OF NATIONAL MUSEUM, 1898. 



This form occurs iu Lower California, Sonora, and Ohihualiua. 



The form which I described as H. chlorophcva differs in its colors some- 

 what from the usual type. It is found in Arizona. Its characters are 

 as follows : 



Number of labials and rows of scales the same as in the last species. 

 The scales of the body are, however, more elongate, and partly on this 

 account are arranged in rows more oblique in an antero-posterior direc- 

 tion. The vertical plate is a little broader, and the head is narrower 

 in proportion to its length. The body is rather more slender. 



The color is a greenish ash, much darker than in the preceding spe- 

 cies. The dorsal spots, instead of being brown, are black and sepa- 

 rated by intervals of two scales in width. They are much smaller, 

 occupying only the space from the ninth to the thirteenth longitudinal 

 rows, and are one scale and a half long. They frequently divide and 

 alternate, and their number on the body amounts to from fifty-eight to 

 sixty-six. Two rows of smaller alternating spots appear on the sides, 

 one upon the sixth and seventh rows of scales, the other on the fourth. 

 The distribution of colors on the head and neck is much as is in the 

 typical form, except that the neck spots are a little longer. The brown 

 is, however, replaced by black, and the ochreous by olivaceous. The 

 crown and muzzle are thickly punctuated with black. Beneath pale 

 olivaceous. Gastrosteges, 167; urosteges, 55.
