8 THE ZOOLOGIST. 
Winter Cove, where a female of L. argentatus was also procured 
the same month. Two males of the latter species were shot in 
July, 1853, at Cambridge Bay, where the eggs were also found. 
There is a further entry of three eggs of L. leucopterus having 
been procured at Cambridge Bay in 1853, but that species is not 
included in Mr. Anderson's list of birds. I am therefore inclined 
to think that the names of L. argentatus and L. argentatoides of 
the list should be considered synonyms for the form of Herring 
Gull which visits Prince Albert Land, and that L. leucopterus may 
very fairly be included as a visitor to that region. . 
L. Sabinti.—A male and female of Sabine’s Gull were killed 
at Winter Cove in June, 1852, and a second pair, male and female, 
at Cambridge Bay in June, 1853. An egg of this species was 
taken at Cambridge Bay in 1858. 
L. eburneus.—-The Ivory Gull is simply recorded as one of the 
species ascertained to visit Prince Albert Land. 
Lestris pomarimus.—Mr. Anderson includes in the catalogue of 
his collection a male of the Pomatorhine Skua. A pair were 
obtained at Cambridge Bay in June and July, 1853. 
Stercorarius cepphus.— Nos. 90 and 91 of Mr. Anderson’s 
Catalogue are thus named, and refer to a male and female Skua 
obtained at Cambridge Bay, July 15th, 1858. I have no doubt that 
Mr. Anderson was guided in his synonymy by Swainson and 
Richardson (Faun. Bor. Amer., ii., 1831, p. 482), and S. cepphus of 
those authors is certainly S. crepidatus (Gm.), Richardson's Skua. 
Lestris Buffonii.—A male and female of Buffon’s Skua were 
shot at Cambridge Bay in July, 1853. 
Procellaria glacialis.—Ascertained to visit Prince Albert Land, 
but no specimen is included in the catalogue of the collection. 
It might possibly be the Pacific form Fulmarus Rodgersi, Cas. 
Colymbus glacialis——In all probability the form of Great 
Northern Diver ascertained to visit Prince Albert Land is 
C. Adamsii, Gray. A male was killed at Winter Cove, June, 1852. 
C. arcticus.—Included in the list of birds of Prince Albert 
Land, and a male and female are recorded as procured at Winter 
Cove, June, 1852. 
C. septentrionalis—This bird was found breeding at 
Cambridge Bay, 1853. 
Anser albifrons.—A male White-fronted Goose was killed at 
Winter Cove, June, 1852.
