Family.— COLUBEIDJE. 

 Tropidonotus piscator (Schneider). 

 Four specimens from Harnai, Sibi, Kirta and Sharigh. All are olive- 

 greenish with moderately large black chequers anteriorly, and quite 

 typical in lepidosis. 



Lycodon striatus (Shaw). 



Three specimens from Quetta. One in particular shows a bright yellow 

 adornment similar in pattern to the white observed in the usual Indian 

 specimens. Probably the others were similar, but the bright yellow is sure 

 to fade in spirit as it does in other Lycodons (jam, Jlavomaeulatus, and 

 fasciatus). The ventrals and subcaudals are 179 ? + 60, 180 + 63, and 

 176 ? + 63. There are 9 supralabials in one specimen on the left side, and 

 the 3rd, 4th, 5th and 6th touch the eye on that side. 

 Zamenis mucosus (Linne). 



Six specimens from Quetta and Hanna. One large adult is unusually 

 dark being a uniform blackish dorsally. In two specimens the loreals are 

 tivo (1 + 1). 



Zamenis rhodorhachis (Jan.). 



Several specimens, all of variety ladacensis (Anderson) from Quetta, 

 Fort Sandeman, Hanna, Duki, Mach, Takatu, Spinkarez (Hanna), and 

 Sibi. The supralabials are 9, the 4th is invariably divided and its upper 

 part touches the eye. I think there can be no doubt that this is the 

 correct interpretation of the condition, and that the upper part of this shield 

 should not be designated a subocular (vide Boulenger's Catalogue, Vol. 1, 

 p. 398). On one side in one specimen the 3rd supralabial is also divided 

 as it normally is in the species raveryieri. The ventrals vary from 218 to 230, 

 and the subcaudals are 131 in the only specimen where the tail is complete, 

 and these shields can be counted. The costals in all are 19 two heads- 

 lengths behind the head, 19 ' in mid-body, and 13 usually (11 once) two 

 headslengths before the anus. The two first steps occur very close 

 together, and are often intermixed but from 19 to 17 the row next to the 

 vertebral usually blends with the one below, and from 17 to 15 

 above the ventrals blends with the 4th (rarely the 2nd). From 15 to 13 

 the row next to the vertebral again blends with the one below. 



In all a regular series of spots of a darker brown than the ground c'olour 

 pass down the dorsum. These spots are usually rather large, and 

 roundish or oval, but in some specimens these are replaced by narrow bars. 



The teeth in this species are quite different from those of ventrimaculatus, 

 the species to which it shows such a very close external resemblance. 

 There is a gap at the back of the maxillary array followed by two 

 enlarged teeth in ladacensis. 



Zamenis liarelini (Brandt). 



Several specimens from Quetta, Pishin, Mastung, Walikhan, Gulistan,
