most of them containing eggs, from one to three in number, on the 10th of 
June. Smaller stations were observed at Cape Borlase Warren, Cape Mary, 
Jackson Island, and other places. Though the Expedition met with 
I. leucopterus, it seems not to have been found breeding, and the size of 
these eggs justifies their assignment to Z. g/aucus. Two of them are so much 
alike that they would appear to be from the same nest, but there is nothing to 
shew the precise locality where any of them were taken. |

Jackson-Harmsworth [xpedition, through Mr. Dresser 
1900. 
By the good offices of Mr. Dresser I was enabled to acquire these eggs from 
Mr. Jackson, the leader of the Expedition, who, writing of this species in his 
work (‘A Thousand Days in the Arctic, ii. pp. 405, 404, says: “ A couple or 
two of these birds we found nesting upon all the Capes rerching from Cape 
Flora to Cape Neale. They built as a rule on inaccessibie points amongst 
the high basaltic cliffs. The only eggs we obtained I secured on June 29th, 
1896, when I found a pair nesting upon the top of the lower tier of rocks on 
Cape Flora.” In Mr, Frohawk’s “ Notes and Pesempeiens of the Eggs” 
collected by the same Expedition (tom. cif. p. 391) a fuller account is 
furnished :—“ The nest was found by Mr. Jackson upon a precipitous grassy 
mound (formed of broken débris from the cliffs above and guano from. the 
Guillemots) above the lower tier of rocks overhanging the talus of Cape Flora 
at an altitude of about six hundred feet above the sea. Mr. Jackson gives me 
the following interesting particulars: ‘The nest consisted of a mass of dried 
grass, feathers, and moss, and was of considerable dimensions. It contained 
two eges. One of the birds, on my approachinz the nest, scattered some of 
the materials of the nest over the eggs, with intent to conceal them un- 
doubtedly. The old birds showed considerable courage in defending the nest, 
swooping down within a foot or two of my head, and uttering loud screeches 
as they passed.’” These eggs are mentioned in Mr, Jackson’s narrative 
(tom. crt. p. 82). 
These eggs are somewhat undersized, measuring respectively 2775 by 2:06 
and 2°87 by 2 inches; but there is no evidence that Z. leucopterus, the ouly 
species likely to be mistaken for Z. g/aucus, occurs in Franz Josef Land. |
