 Belly yellovdsh, with black cross bands or quadrangular black spots. 



Var. a. Belly with uninterrupted black cross bands, alternately limited to the belly, or 

 extending up the sides of the body, so as to cover scales of the four outer rows and give

 trunk form complete rings crossing the vertebral line; tail with three other black rings. 

 This specimen is 2Q^ inches long, tail 2^ inches. Ventrals 218; subcaudals 28.

Var. y. The cross bands reach entirely across the back, forming rings, from twenty-two to 

 twenty-eight in number; no black vertebral line, which, however, is indicated by isolated 

 small spots. Ventrals 196-218; subcaudals 27-34.

Head and neck black above, with a broad yellow cross band behind the eyes. Body and 

 tail reddish brown, without longitudinal band, but with forty narrow, equidistant, black, 

 white-edged rings ; each of them is about as broad as a scale on the back (those round the 

 tail being broader), and occupies one ventral shield on the belly. Belly yellowish, with a 

 black cross band in the middle between the rings; each of these cross bands occupies a 

 ventral shield, so that about every third ventral is black.

 Ventrals 208 ; anal bifid ; subcaudals 33. 



I have examined only one specimen of this species, remarkable on account of its singular 

 coloration. It is marked "India" ; and 19 inches long, the tail measuring 2 inches.
