64 Catalogue of Reptiles. 



In our adult specimens a. and I., the 3rd upper labial is undivided, 

 and therefore just enters the orbit with its posterior angle. In the 

 young, the anteocular touches the vertical as described by Giinther, 

 but does not quite reach it in either of the adult specimens a. b. and d. 



ZAOCYS, Cope.

a. skin and tail of adult, Darjiling. Major Sherwill. 



b. several ditto. S. E. Himalaya. 



HEKPETOBEAS, Gunther. 



H. Sieboldi, Griinth. Sikim. 



Scales in nineteen rows, feebly keeled on the back. Anal and sub- 

 caudals bifid. Eostral broader than high, convex just reaches the 

 surface of head. Anterior frontals sub-pentagonal, broadest behind, 

 rather more than half as large as the posterior frontals, which are bent 

 down at the side. Yertical, superciliaries and occipitals normal, pro- 

 portionate. Nostril between two largish nasals. Loreal small, smaller 

 than nasal. Anteoculars two, the upper large, but does not touch ver- 

 tical. The lower small, wedged in between the third and fourth labials ; 

 looks like a detached piece of the third labial. Postoculars two, small, 

 the lowest in contact with two temporals. Upper labials eight, the 

 fourth and fifth enter the orbit. m 



Chin shields two pair, contiguous, touching six lower labials. First 

 lower labials form a suture, second very small, sixth largest. 



Eye large, pupil round, ventrals strongly upturned at the sides, the 

 upturned ends being dark coloured. Colour above olive brown. A black 

 band down each side of spine from neck to tail, with an interspace of 

 five scales between. A second narrower band two scales below the last. 

 Belly dusky, throat yellow. 



A' black streak from eye to gape. 



This description is taken from a specimen in the possession of 

 Mr. Grote. 



One specimen exists in the museum, as far as I can judge, without 

 extracting it from the bottle. It differs from the above and agrees 

 with the type in having only one anteocular ; but as in the above speci- 

 men the eye is on the 4th and 5th upper labials, whereas the type has 

 three upper labials entering the orbit, this is probably an individual 

 peculiarity.
