EUTAINIA. 29 



more or less confluent above with each other, and with those on the 

 opposite side ; the blotches about one scale apart. The intervals 

 between the blotches of a vivid brick-red, which color, as well as the 

 black, is sometimes seen on the bases of the adjoining scales. None 

 of the short white lines of E. sirtalis ai-e visible. More or less of 

 white on the inferior surface of the tail. 



The color when living, as described bj Say, is black-brown above, 

 beneath bluish green, bead beneath white. A vertebral greenish 

 yellow line, and a lateral pale yellow one : about eighty concealed 

 red spots or semifascias on the skin and lateral margin of the scales.

'Y. Eutainia lepfocepliala, B. & G.— Scales on the greater 

 portion of tail scarcely carinated. The two exterior dorsal rows on each 

 side unequal, but conspicuously larger than the rest ; outer one not cari- 

 nated. Head slender, plane above. Orbitals 3 posterior; 2 anterior. Above 

 light olive-brown, with distinct small brown spots, 130 in a series from 

 head to anus. 



Exterior row of dorsal scales broader than usual, not carinated j 

 second smaller, but also broader than usual, and faintly carinated. 

 Top of head nearly plane from occiput to anterior frontals. Head 

 narrow and depressed. Eyes small. Labials narrow. Scales on 

 sides of anus not conspicuously smaller. 



Color dull light olive-brown or light chocolate, beneath pale green- 

 ish slate : when the epidermis is removed, the subjacent skin of the 

 abdomen is seen minutely punctured and clouded with black, so as to 

 impart this latter color to the whole, except near the edge. A ver- 

 tebral dull yellowish line on a single row of scales which appears 

 more prominent than the rest. On each side of this vertebral line 

 are two series of subquadrate black spots, about 130 from head to 

 anus, on about every other scale, or even closer, and showing very 

 conspicuously on the clear ground-color. Bases of all the scales on 

 the sides of the body are more or less black, occasionally showing 

 beyond the incumbent edges. Little or no indication of a lateral 

 stripe. The lower series of black spots is continued in a faint line 

 along the side of the head to the orbit. In one specimen the color- 

 ation is less defined, showing a greenish white color above, with tessel- 

 lated small spots of black.
