PROCEEDINGS OF THE 



glaucus^ and L. marhmis. I say reasonably suppose, because it was 

 not until very long afterwards that we met with these species. 

 They are Nos. 66, 67, 77, 79, 80, 81, 83, 90, 107, 108, 109, 110, 

 111, and also 39, 71, 75, 95, 96, 98, 103, 104. The first 13 of 

 these we afterwards met with only on the tundra and the far-out 

 islands of the Petchora Gulf; and the other 8 were found on the 

 river and its islands, but considerably to the north. Of each of 

 Nos. 4, 53, 54^, we got only one specimen; and they may or 

 may not have passed Ust Zylma. 



If we consider, however, that Phylloscopiis tristis, an eastern 

 species and of the same group as 53 and 54^, was not uncommon 

 at Ust Zylma, then there is a probability that these latter also would 

 find their way north by a not very different route. No. 57 we did 

 not see on migration, because we had no opportunity of visiting 

 suitable ground at the right time ; but very soon after leaving 

 Habariki, we found it in full song amongst the willow thickets. 

 No doubt, could we have reached the west shore of the Petchora, 

 opposite Ust Zylma, between the 22d May and the 10th June, we 

 would also have been able to add it sooner to our list. We were 

 prevented from doing this by the flooding of the river and the 

 stream of ice. 



For convenience of comparison of the dates of arrival of 

 migratory species at Ust Zylma and in Egypt, I append the 

 following table : — 



A comparative Tahle of the arrivals of Birds in Egypt, and in the 

 district around Ust Zylma and Habarild, in N.E. Ilussia. 



* Upon an examination of such papers as I have access to upon the Birds 

 of the countries bordcrini,^ the coasts of the east of tlie Mediterranean, I can 

 find no record of the occurrence of Lams rjlaucns, and very few records of 

 its occurrence in the Mediterranean at all. Salvador! sa^s that L. fjlaucus
