as head; one series of numerous brown bars connecting the light stripes, 

 none of which are black-edged. — Mexico.

 the last 3 upper labials, none of which are reduced; superior labials 8 (7); 

 general color brown; large nuchal blotches, and a double series of very 

 small, lateral spots, black; latter forming continuous zigzag on stretched 

 skin ; no black margins. 



"E. ornata, B. and G. — Form slender; tail 3 or § in total ; head nar- 

 row, elongate ; loreal longer than high ; 4 superior labials, temporal not 

 extending beyond penultimate ; above uniform, except on stretched skin, 

 where there is a broad border to dorsal vittae, and one lateral row of black 

 spots separated by rufous. 



U E. infernalis, B. and Gf., Catalogue. — More slender than any species of 

 this section. Head and eye large; above black; a series of about 110 

 triangular, reddish-yellow spots, confluent with the indistinct lateral stripe, 

 itself confluent with the greenish-white sides and abdomen. 



"E. pickeringii, B. and Gr. Catalogue. — Body slender; black above, slate- 

 color beneath ; lateral stripe irregular, confluent with the light-colored inter- 

 vals between the dark spots. This species exhibits great variation of color, 

 principally in regard to black of abdomen. 



"E. leptocephala, B. and Gr., Catalogue. — Scales on the greater portion of 

 the tail scarcely carinated. The two exterior dorsal rows on each side 

 unequal, but conspicuously larger than the rest, outer one not carinated ; 

 head slender, plain above ; orbitals, 3 posterior, 2 anterior ; above light 

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

 to anus beneath pale-greenish slate ; little or no indication of a lateral stripe. 



U E. slrtalis, B. and Gr., Catalogue. — Body among stoutest of their form; 

 olive-brown, above the lateral stripes sometimes nearly black, beneath them 

 greenish- white ; dorsal stripe narrow, encroached upon by the spot ; lateral 

 stripes inconspicuous; two or three rows of small, indistinct spots, often not 

 perceptible, especially the lower, about 70 from head to anus.
