NOTES ON SNAKES COLLECTED Ji\ UPPER ASSAM. 831 



was gravid on the lOtli of July and contained i} eggs. The supra- 

 labials were 6, the 4th and 5th touching the eve in one specimen. 



Simoteff violaceous (Cantor). 



Only two examples were obtained, one from near Tinsukia, and one 

 from near Halem (Baroi). Both belong to variety D of Boulenger's 

 Catalogue (Vol. II, page 223). In both the ventrals and subcaudals 

 were 177 + 31 (Boulenger : subcaudals 38 to 41). In one there 

 was a small median prgefrontal. 



Ol'xjodon dorsalis (Gray). 



A single specimen was sent me by Mr. Gore from Namsang, 

 W. Jaipur. This was a $ 12f inches long, the tail being 1^ inches. 

 The ventrals were 173 and the subcaudals 29. The scales two heads- 

 lengths behind the head were 15, in midbody 15, and two heads- 

 lengths before the anus 13, as is usual in this species. 



SUB-F AMIL Y — HOM ALO PS IN.E . 



Hypsirliina enhydrk (Schneider). 



One specimen from Dibrugarh was brought in to me, a ^ 1 foot 10 

 inches long, the tail 5^ inches. It agrees with variety B of Boulenger's 

 Catalogue* (Vol. HI, p. 7). The ventrals and subcaudals were 

 153 •+- 74. The costals were in 23 rows at a point two heads-lengths 

 behind the head, 21 in midbody, and 20 at a point two heads-lengths 

 before the anus. The 3rd and 4th rows above the ventrals blended at 

 both steps reducing the rows from 23 to ] 9. 



Sub-family — Djpsadomokphin^. 



Dipsadomorphus gokool (Gray). 



I got four examples of this uncommon snake, three in Dibrugarh, 

 and one from North Lakimpur (Dejoo). One of these was brought 

 alive, and behaved just like others of the genus with which 1 am 

 acquainted. AH are very plucky snakes. This one coiled itself in the 

 typical figure of 8 fashion, and erected itself and poised, thus awaiting 

 an opportunity to strike at me, quivering the tail with anger. 



♦ I ma> here mention that I received a similar specimen lately from Ohamparan (Behar) 

 from Mr. H. Raid. This locality zoologically is part of that with which this paper deals. 

 The costals were 25, 21, 21, in the three sites corresponding to the above. The ventral* 

 and subcaudals were 158 4-59 The stomach was much knuckled and thickened, and full 

 of nematode worms which I think were Knlicephalas willeyi,
