rently entire; the shrunken state of the specimen did not allow a 

 satisfactory examination to be made. 



The ground-color of the head and body above is a deep chestnut. 

 On the posterior part of the head is a yellow ring, sending a narrow 

 stripe along the upper labials to the orbit. Each scale is provided 

 on its middle with a narrow and elongated yellow dot, very conspicu- 

 ous on the outer row of scales, giving at first the impression of a 

 narrow vitta along the sides. The exterior edge of the abdomen is of 

 the same color as the back. The abdomen is yellowish ; a medial 

 chestnut band extends from the head to the tip of the tail, interrupted 

 only by the narrow yellowish margin of the scutellge themselves.
