Spilotes corais xanthurus, subs. nov. 



Two specimens from an unknown locality. There is good reason, 

 however, to believe that they came from Vera Cruz. 



(a) 17 rows of smooth scales ; 8 upper, 9 lower labials ; temporals, 

 t -2 ; ventrals, 215; subcaudals, 77 pairs. Total length, 1,575 mm. 

 {tail 279). 



(6) 17 rows of smooth scales; 8 upper, 9 lower labials; tem- 

 porals, 2-2 ; ventrals, 204 ; subcaudals, 58 pairs. Total length, 

 1580 mm. (tail 229). 



Color is alike in both specimens : The upper surface of head is 

 brownish black, with a yellow shade showing through it. The 

 upper labials are yellow, margined above and behind with brownish 

 black. The body is blackish brown above for the anterior two- 

 thirds, gradually becoming blotched with yellow, which increases un- 

 til the posterior third is entirely orange yellow; some scales are with 

 dark edges. Under surface of head and throat yellow. The portion 

 of the body which is black above, is a pale dirty yellow beneath, the 

 color of the back showing on the ends of the ventrals ; the posterior 

 portion below, being a clearer, brighter yellow. 



In specimen a the lower anterior temporal is long and narrow and 

 on one side is divided, making three on one side and two on the 

 other. In specimen b the anterior temporals are small, hardly 

 larger than the post-orbitals and ai*e almost separated from the 

 posterior pair by the seventh labial, which is produced upward into 

 a point. 



Alsophis angulifer caymanus (Garmaii). 



Three specimens from Isle of Pines, West Indies. 



17 rows of scales, smooth ; 1 ante, 2 post-orbitals ; a square loreal, 

 not reaching the frontal ; 2 nasals ; temporals, 1-2 ; 8 superior 

 labials, 3d, 4th and 5th in orbit; 10 lower labials; 2 pairs of chin 

 shields ; anal divided. 



(a) Ventrals, 172; subcaudals, 109 pairs. Total length, 1,273 mm. (tail 356). 

 {b) " 169 " 81 " " " 1,146 " " 305 



(c) " 169 " 80 " " " 1,133 " " 292 



Color, pale olive brown above, each scale edged with blackish ex- 

 cept towards the tail, where the edging disappears and an occasional 

 scale is wholly black. The ventrals are slightly lighter, each one on 

 the anterior portion of the body edged with black. There is an
