 scallops there arc white spots. Below the' dark hand a 

 lighter one extends from the car to the thigh : and below 

 this on the Hank there is another dark hand with irregular

Nostril between the two nasals; occipitals irregular, 

 six or more ; supraoculars three ; on one specimen a fourth 

 hardly larger thin the granules is present; snpraciliaries 

 seven to nine; loreal undivided; labials six to seven. 

 Lower labials six to seven ; submentals one anterior and 

 six or seven pairs; gular grannies much enlarged in a 

 band across the throat ; mesoptychium with a band, of six 

 or seven scales longitudinally and about twenty trans- 

 versely, in which the largest are larger than the gulars ; 

 two bands of slightly enlarged granules between the gu- 

 lar band and the fold. Dorsal granules small, smooth, 

 larger than those of the flanks. Ventrals in fourteen 

 row-, outer small: transverse series thirty-three. Pre- 

 anal plates in a single longitudinal series of four larger, 

 surrounded by smaller plates of which one at each side of
