Plate 15, fig. 12, 13. 
Culebrita. 
Diagnosis: — A small burrowing snake red above and white below with 
two dark lateral stripes and generally a darker dorsal brown band. Size less 
than the preceding species, usually about ten inches. 
Description: — Adult M. C. Z. 10,846. Cuba: 10 miles 8. W. of Aguada 
de Pasajeros, near Rio Hanabana, Spring of 1915. Thomas Barbour. 
Rostral much broader than high, barely visible from above; internasal 
suture far shorter than prefrontal suture; frontal one and one third as long as 
broad, as long as its distance from the tip of snout which is about the same as 
the parietal suture; nostril small, pierced in a single nasal; loreal moderate, 
rectangular, longer than high; one small preocular, two postoculars the upper 
the larger; temporals 1 + 2; seven upper labials, third and fourth entering 
eye; four lower labials in contact with the anterior chin-shields; seventeen 
rows of smooth scales around the body; 123 ventrals, anal divided, seventy-one 
subcaudals. 
Colour (in life): — Bright brick-red, a dark brown band from the middle 
of the third to the upper third of the fourth rows of scales; no evidence of a 
median middorsal stripe. Lower surfaces cream-yellow. 
Dimensions: — Total length 244 mm. 
Length of tail 82.2 mm. 
M. C. Z., 7,925 from near Cienfuegos, 1910, R. M. Grey collector, is the 
same as the specimen described in colour except that it has faded slightly and 
has a distinct middorsal stripe. Its scale counts are 115 ventrals, anal divided, 
fifty-three subcaudals. 
M. C. Z., 7,952 from near the Rio Anallo, Cuba, collected by Barnum 
Brown and received in exchange from Amer. Mus. Nat. Hist., 1910, is exactly 
similar to the preceding in colour and counts 122 ventrals, anal divided, sixty 
subcaudals. 
We cannot see that this species differs from the preceding in habits or 
distribution. We have seen no specimens nearly as large, nor none in which 
the rostral region is modified as in the specimen of A. taeniatwm described or
