Phalacrocorax cirriger. 



Phal. supra fusco-griseus, suhtus albidns; guld, cirroque longitudi- 

 nali per collum titrinqiie descendente, albis; roatro pedibusque rubris ; 

 rectricibus qitatuordecim. 



The middle of the feathers of the back and of the wing coverts are of 

 a hghter colour than the rest of the feather, as is usual in tliis genus. 

 The tuft which descends from the throat on each side of the neck is 

 about three inches in length. The under wing coverts are of the same 

 griseous colour as the back. The quill and tail feathers are fuscous; 

 the latter are rigid with narrow webs, and are much worn. The length 

 of the body is 26 inches; of the bill, 3y'^; of the wing from the carpal 

 joint to the extremity of the third quill feather, 10; of the tail, 6; 

 of the tarsi, If.

 I have ever seen. 



LaRUS HiEMATORHYNCHUS. 



Lar. corpore plumbeo-griseoy dorso medio alisqiic nigris, his albo 

 notalis ; rostro pedibusque sanguineis. 



The general colour of this bird, including that of the head, neck and 

 abdomen, is of a light leaden gray. The tail is lighter. The middle 

 part of the back is fuscous inclining to black ; the quill feathers are black, 

 the two outward ones entirely so, the third slightly tipped with white, 

 and the rest with the white tips gradually increasing. The under wing 

 coverts and quills beneath are of a plumbeous colour, rather darker than 

 that which prevails on the neck and abdomen. The length of the bird 

 is 18 inches; of the bill, 2; of the wing from the carpal joint to the 

 end of the first quill feather, 13; of the tail, 6 ; of the tarsi, 2. 



67, 68. A large species of Gull which I consider to be the same 

 as our lesser black-backed species, Larus fuscus. As far as my recollect
