THE TUBE-NOSED SWIMMERS - T CLIN ARES. 



Hab. Farallon Islands, coast of California. 



Sp. Char. Adult: Smoky plumbeous, the wing-coverts lighter and more brown, the reniiges 

 and tail dusky; rump and upper tail-coverts ashy plumbeous; anterior portion of the head 

 inclining to ashy. Bill deep black ; legs and feet brownish black. 



Wing, 5.30-5.40 inches; tail, 3.30-3.50, depth of its fork, .70-.9O; culmen, .50-55 ; tarsus, 

 .80-.90 ; middle toe, .75-.80. 



This has been one of the species doubtfully attributed to the Califomian coast, the 

 occurrence of which has only recently received verification. It had not been met with 

 there by Dr. Cooper, and until identified by Mr. Henshaw, there was no satisfactory 

 evidence in support of its claim to a place in the fauna of North America. But little 

 is known as to its habits, its distribution, or the places to which it resorts for breed- 

 ing. Mr. Henshaw states that Petrels appear to be cpiite numerous along the entire 

 coast of California. He received an example of this species from Captain Forney, who 

 had procured it on San Miguel, where it was said to be breeding in great numbers. 

 As usual with this family, it was nesting in burrows. 



Genus OCEANODROMA, Beichenbach. 

 Oceanodroma, Reichenb. Av. Syst. 1S52, p. iv (type, Proccllaria furcatu, Gmel.).

Char. Size of Cymochorca ; tail more than half as long as the wing, forked, the feathers 

 narrowed and scalloped out toward ends ; tarsus scarcely longer than the middle toe and claw 

 (less than twice the culmen) ; plumage ashy, with or without white collar and lower parts.
