pears to be the commocest variety, this is the '* Keautiah " of Payrer 

 and "var. ^" of Giinther who also records it from Assam and Sikhim, 



c. Hood as above with the circular marking ; uniform brown above, 

 below, anteriorly light coloured, posteriorly darker. 



In the Indian Museum examples from Assansole, Bengal, Calcutta^ 

 Sibsagar and Saraagooting, Assam, Chittagong and the Andamans. 



This is the variety most commonly met with, I believe, throughout 

 Burma, it appears to correspond to " var. t, " of Giinther which he re- 

 cords from Siam. 



d. Hood with no marking, light coloured above and below with 

 darker pectoral bands. 



The Indian Museum contains examples of this species from the 

 Rungpur district in Bengal, from Assam, the Chittagong hills, Mandalay 

 and Mergui. 



e. Hood with no marking, blue black above and below except slight 

 traces of lighter colour on each side of the throat. 



The Indian Museum contains examples of this well-marked variety 

 from the Andamans (?) and Singapore, where it appears to be very 

 abundant. 



It seems to correspond to part of " var. e " of Giinther, 



/. No marking on the hood ; very dark brown, almost black above 

 and below. 



The Indian Museum contains examples of this variety from the 

 Punjab and Raj pu tana, and this is probably the same as part of Giin- 

 ther's " var. e " which came from the Deccan. 



g. N^o marking on the head, colour a light sandy with bluish tinge -, 

 two dark bands on the neck extending all round, behind these two an- 

 terior bands a series of chevron-shaped forwardly directed bands, which 

 become fainter towards the tail. 



There are examples of this curiously coloured variety in the Indian 

 Museum from Khojak in British Baluchistan and from the Punjab. 



This variety was first described by Eichwald as Tomyris oxiana and 

 has been shown by Boulenger and Boettger to be conspecific with the 

 typical N. trijpudians.
