Family— COLUBRIM. 



Series A. — Aglypha. 



Sub-family — Colubrin^e. 

 Tropidonotus tessellatus. 



Two specimens. 



The lowest prseocular is minute. As in other Tropidonoti the re- 

 duction of the costal rows from 19 to 17 is effected by a coalescence 

 of the 3rd and 4th rows above the ventrals. Keels are absent in the 

 ultimate row, only in about the anterior two-thirds or so of the 

 body. Apical pits are very obscurely visible in pairs, at any rate 

 anteriorly. The nasal is semidivided, a suture running from the 

 nostril to the 1st labial. 



Zamenis rhodorhachis. 



Four specimens. One is a very beautiful example of variety typica, 

 with a very bright pink vertebral stripe. The others conform to 

 variety ladacensis.
