238 W. L. Sciater — Notes on the Snakes in the Indian Museum. [No. 3, 



Zamenis venteimacdlatus, (Gray), Boulenger, p. 325. 

 Zamenis ladaccensis, Anderson, Boulenger, p. 326. 



There are no specimens of Z. ventrimaculatus in the Indian Museum 

 from Persia or anywhere outside the Indian Empire. The Museum 

 possesses examples from the following localities. Below Simla, Sabathu, 

 liajanpur in the Punjab, Jeypore Rjpt., and Karachi. Of Z. ladaccensis 

 the Indian Museum possesses specimens from Sliiraz (including the tjpe 

 of Gonyosoma dorsalis, Anders) Bushire, Karmau and Regan in Persia ; 

 Askan, Zamran, Hung, and Quetta in Baluchistan ; Gilgit and Ladak. 



If this really represents the true distribution of the two species 

 their geographical areas are quite separate and the two species may be 

 considered quite distinct. 



Zamenis diadema, (Schleg.), Boulenger, p. 328. 



The distributional area of this snake may be extended eastwards as 

 far as Allahabad perhaps as far as Purneah, as there is a specimen pro- 

 bably from the latter place in the Indian Museum.

Rostral as broad as deep, just visible from above ; suture between the

 two postoculars ; a single pair of long temporals on either side, the pos^ 

 terior temporals not larger than the ordinary scales ; upper labials 7 to 8

Colour, black above to greenish olive on the head, anteriorly traces 

 of a white vertebral line, in the middle part of the body a series of ill 

 defined white transverse bands bordered with black posteriorly, on the 

 hinder part of the body, the bands are gradually transformed into seven 

 longitudinal series of white spots separated by a black network, of the 

 series of spots the outer series on either side are on the ventrals ; below
