The liistory of the manners and our 

 knowledge of the distribution of this spe- 

 eios is wanting. All that is known in 

 regard to it is that it was first referred to 

 as one of our Western coast-birds by Mr. 

 Lawrence, under the name of Proeellaria 

 hcrsitata, based upon an example said to 



liave been killed oif the coast near Monterey, and found in the collection of N. I'ike, 

 Es(i. Afterward, in the "Pacific Kailroad Keports," Vol. IX., it was given as 

 ruffimis cinereus. 



In the "Proceedings of the Philadelphia Academy," 1862, IMr. Cassin describes 

 as P. Kuhlii certain examples that had been taken, Sept. 11, 1853, by Professor 

 F. IL Storer, of the Rogers Exploring Expedition, about fifty miles off the Cape 

 of Good Hope. These are regarded as identical Avith the Monterey example ; and 

 these two instances of the occurrence of this species in widely separated localities 

 constitute the sum of our scanty knowledge of its distribution.
