In this subspecies melanism is carried farther than in any of the 



others. The typical specimen is of an intense black, tinged with bluish 



below. There is a very nar- 

 row greenish white vertebral 

 line, beginning at the nape, 

 where it occupies one and 

 two half scales, and gradu- 

 ally narrows to the carina 

 of the middle dorsal row, 

 becoming obsolete at the 

 anus. The carina? of the 

 second and third rows of 

 exterior dorsal scales show 

 the faint line of greenish 

 white, only perceptible on 

 close observation. The 



lores, labials, cheeks, and head beneath, greenish white, gradually 



shading into the blue-black of the abdomen at or about the anterior 



fifth. Scuta, 158-1-73.
