TYPE SPECIMENS OF BIRDS 37 



According to the rules set up for this study, all the original material 

 should be considered cotypes, but it is obvious that Stejneger's series of so 

 common a bird must have been enormous even in 1885, and it would be 

 impracticable to attempt here to list them all. In this case, then, the one 

 specimen from the restricted type locality is treated as the only type. 



Genus BUCEPHALA Baird 



Clangula barrovii Richardson 



in Swainson and Richardson, Fauna Boreali-Americana 2 (The birds) : 

 456, pi. 70, February 1832. 

 =Bucephala islandica (Gmelin). See Baird, Cassin, and Lawrence, Rep. 



Expl. and Surv. R.R. Pac. 9: 796-797, 1858. 

 2723. Adult male. "Iceland ?"=0n the Rocky Mountains. 1826 or 1827. 

 Collected by Thomas Drummond (see Richardson, op. cit.. Introduc- 

 tion, p. xv). Received from Spencer F. Baird, who acquired it from 

 John J. Audubon. 

 Baird listed this bird in his private register as from "Iceland?," indicated 

 that he had it from Audubon, and stated further that it had reached the 

 latter from Gould. This last is an incorrect assumption, inasmuch as Audu- 

 bon himself observed that the specimen "was presented to me by the [13th] 

 Earl of Derby, to whom it was given by a member of one of the late Arctic 

 Expeditions" (see Ornithological biography 5: 105, 1839). 



Blakiston (Ibis, p. 148, 1863) remarked that the type of Clangula barrovii 

 was "in the Museum of the Smithsonian Institution at Washington," and 

 Baird (op. cit., p. 797) wrote that No. 2723 "appears to be the one upon 

 which the species was based in the F. Bor. Americana." 



Genus MELANITTA Boie 



0[iclemla]. stejnegeri Ridgway 



Manual of North American birds, p. 112, 1887. 

 =Melanitta fusca stejnegeri (Ridgway). See Peters, Checklist of birds 



of the world 1:181, 1931. 

 101205. Adult male. Bering Island, Commander Islands, southwestern 

 Bering Sea. March 1884. Collected by N. Grebnitsky. Original 

 number 78. 

 101206. Adult male. Bering Island, Commander Islands, southwestern 

 Bering Sea. April 1884. Collected by N. Grebnitsky. Original 

 number 79. 

 No type was mentioned at the original description, but reference was made 

 in a footnote to "O. deglandii Stejn., Orn. Expl. Kamtsch. 1885, 174." There 

 Stejneger stated that he had three males, one of them immature. Since 

 Ridgway's description treated only of the adult, the specimens here listed 

 are the cotypes.
