Thamnophis leptocephala olympia, var. nov. 



One specimen, Cat. No. 486; total length, 21.84 inches; 

 body, 16.15; tail, 5.09; scales, 17 rows; gasterosteges, 144 ; uros- 

 teges, 56 ; one preocular ; three postoculars, the middle one the 

 larger ; 7 upper labials, the 3d and 4th entering the eye, the 5th the 

 largest ; 9 lower labials, the 5th the largest ; temporals, 1-2 ; length 

 of frontal equals its distance from the rostral ; rostral broader 

 than deep, only its tip seen from above ; the suture between the 

 prefrontals extends to middle of the frontal. The preorbital is 

 broadest at upper part of orbit, and narrows downward. Scales 

 on the body carinated, except the lower row on each side, which 

 have only a few scales faintly carinated. Scales of the outer 

 rows very little larger than on second rows on anterior and pos- 

 terior parts of the body, the difference being greater on the 

 middle of the body. Head rather small, and not very distinct 

 from the body. Nearly all of the scales of the tail carinated, 

 only those of lower row, and most on last third of tail not keeled ; 

 color in alcohol, a dark green, no light dorsal or lateral stripes ; 

 head, same color of the body. A dark stripe from eye, back on 

 4th and 5th rows of scales ; this band breaks into small irregular 

 spots, which are scarcely traceable on sides, only a short dis- 

 tance. Very little black appears on the scales, except near the 

 head. A few scales on sides have dark edges ; belly uniformly 

 greenish, anteriorly, becoming marbled, with small dark spots, 

 posteriorly ; these dark spots disappear on under surface of pos- 

 terior half of tail. 



This variety differs from Thamnophis leptocephala, in having one 

 preorbital, most of the scales on the tail keeled, no small 

 dark spots in a series from head to tail. The scales are in 

 17 rows ; there are no dorsal or lateral stripes. 



Thamnophis rubristriata sp. nov. 



One specimen, Cat. No. 485 ; total length, 20.62 inches; body, 

 15.37 ; tail, 5.25 ; scales, 17, 151, 67 ; preoculars, 2 ; postoculars, 3 ; 

 the postoculars subequal in size, middle one slightly larger ; upper 

 labials, right side, 8 ; left, 7 ; the second and third on right side 

 corresponds to second on left; the one articulating with lower 

 postorbital, the larger; frontal equals its distance from tip of 

 snout; temporals, 1-2; lower row of scales on each side the larger, 

 few near middle of the body being slightly keeled. The difference
