648 Memorandum relative to the seven CSsis of Nepal. [Dec. 



north and east of the Kuti pass, being probably the nameless peak 

 which Colonel Waugh conjectures may rival Kangchangjtinga in 

 height. The river flows from the base of Deodhunga past the town of 

 Kuti, and has a S. West direction from Kuti to Dallal ghat, where it 

 joins the Milamchi after a course about as long as the Milamchi's, — the 

 two rivers, of nearly equal size, forming a deltic basin. In about its 

 mid-course the Bhotia Cosi is joined by the Sun Cosi from Kalingchok. 

 But Kalingchok is no part of the true Hemachal, nor is the stream 

 thence flowing equal to that coming from the snows at Deo dhunga. 

 Consequently the name Bhotia Cosi should prevail over that of Sun Cosi 

 as the designation of one of the separate seven Cosis, and the name 

 Sun Cosi be reserved for the general receptacle, within the mountains 

 as far east as Tirbeni. The Bhotia Cosi is joined at Listi by the Jiim 

 Khola, whilst from the Manga ridge another feeder is supplied to it, 

 much loAver down or below the confluence of the Sun Cosi, from the 

 east. But as the Milamchi below the junction of the Balamphi and 

 Jhari is often called the Indravati vel Indhani, so the Bhotia Cosi below 

 the junction of the Sun Cosi is frequently styled by the latter name, 

 which others again with more reason confine to the more general con- 

 fluence below Dallal ghat. There no doubt the name Sim Cosi begin s 

 to be well applied, it being universally the designation of the great 

 receptacle of waters running W. and E. from Dumja to Tirbeni. At 

 Dumja, which is only a few miles south of Dallalghat, the Sun Cosj 

 receives a considerable affluent from the west. This affluent is called 

 the Rosi. It rises on the external skirts of the great valley under the 

 names Biyabar and Panouti, from the respective dales watered by the 

 two steamlets. 



3rd. The Tamba Cosi. It rises at Phallak in the snowy region, about 

 two journies east and a little north of Kalingchok, or the fount of the 

 upper and pseudo Sun Cosi. The Tamba Cosi's course from Phallak 

 to Selaghat, where it falls into the receptacle, is nearly south, and as 

 far as I know it has only one considerable affluent, which is the Khimti. 

 The Khimti rises in the Jiri ridge and flowing nearly south, parallel to 

 the Tamba Cosi, joins the latter in its mid-course at Chisapani. 



4th. The Likhii. This river is less than the Tamba Cosi and seems 

 to rise somewhat beneath the snows, though its place of origin at Khali 

 Mungali is said to be a ridge connected therewith. Its course is still 

 more directly south than that of the Tamba Cosi, to which however its
