 found them at their nesting grounds, 300 miles further 

 north. 



The passage thus appeared to occupy a very short 

 space of time at Ust Zylma — only some ten days — the 

 S s bulking commonly between the 10th and 15th, 

 followed by the ? s, mostly between the 15th and 21st. 



The Lapland Buntings' migration was somewhat 

 similar. None were seen till the 18th of May, and then 

 they came in fair numbers. Between the 18th of May 

 and 27th, we accounted for 12 males and 5 females.

The first Eed-throated Pipit were a little later than the 

 last, the first having been seen on the 28rd ; but they 

 were not numerous till the 26th, when we got 10 J s and 

 only 1 ? , and we saw little more of them till we reached 

 the Tundra. 



I need not pursue the subject in detail with all the 

 other species met with, though this could easily be done 

 on the same lines. Sufiice it to say, the same, or nearly 

 the same, proportions of males to females was generally 

 exhibited by species passing Ust Zylma ; and even by the 

 end of our season and into the breeding time, we found 

 difficulty in making up our completer sets of females. 

 Discrepancy, however, in the nesting season cannot be 

 looked upon as important, but rather occasioned by the 

 greater secretiveness of the females whilst engaged in 

 laying and brooding. 



I might follow the analysis even into our voyage down 

 the river and instance similar features amongst such 

 species as Budytes citreoliis and Motacilla fiava,
