extending down the side of the neck. These feathers vary from \ 

 inch to 1-1 inches in length. 



So far as I am aware, this species has never before been placed in 

 the same genus with F. arctica, having usually monopolized one 

 entire genus. Its relationship is unquestionably nearest to the Puf- 

 fins, and it shows so many of the characteristics of this group that I 

 have been led to rank it as only another species of the genus Frater- 

 cula. In many points it seems to be intermediate between the 

 Puffins and the Phaleridine group. Thus the outer claw, though 

 much more curved than in any other genus, is not so much so as in 

 the other members of this genus, while the bill lacks the deep sulca- 

 tions so prominent in them. But the structure of the bill, the size, 

 the feet and claws, the number of the tail feathers, and, in short, the 

 entire make-up of the bird, is sufficient in my estimation to identify 

 it with this genus. Two specimens.

Genus Phaleris 1 Temminck. 



Species not exceeding ten inches in total length, and with the nos- 

 trils entirely unfeathered. Usually with a crest, or with elongated 

 feathers about the head. Bill variable; sometimes simple, oftener 

 irregular, with various elevations and depressions, often with nodules 

 or other accessory elements; always stout, more or less compressed, 

 shorter than the head, the culmen convex, tip acute. Wings and 

 tail of ordinary shape and length. Feet small and short; tarsus 

 compressed, reticulate, shorter than the middle toe. 



The genus thus considered contains the following species: 



5. Phaleris psittacula. 



Alca psittacula Pallas, 1769. Phaleris psittacula Temminck, Ste- 

 phens, Bonaparte, Gray. Omtria psittacula Eschscholtz. No speci- 

 men. 



6. Phaleris cristatella. 



Alca cristatella Pallas, 1769. Alca tetracula Pallas. Simorhyn- 

 chus cristatellus Merrein, Brandt, Coues. Phaleris cristatella Audu- 

 bon. P. tetracula Steph. 



1 As I have examined only one species of this genus, I give essentially the gen- 

 eric description of the genus Simorhynchus, hy Dr. Coues, only wording it so as to 

 iiidude P. aleutica, which he refers to the genus ttychorhaniphus Brandt, but 

 which seems to me to belong properly with the forms here included. (See Proc. 

 Phil. Ac. Nat. Sci., 1868, p. 34.)
