"igie J Nichols and Mowbray, Two New Petrels. 195 



Pufiinus puffinus bermudae subsp. nov. 



The type, a skin, Coll. of L. L. Mowbray, March 10, 1905, sitting on a 

 single white egg in a crevice in Gurnet Head Rock. 



Close to the Manx Shearwater of which it is made a race, but differing 

 from that species about as much as does P. yelkouanus of the Mediterranean. 

 Slightly larger than puffinus, with less gray on axillars and under tail- 

 coverts than yelkouanus. The three should probably stand as geographic 

 races. 



Above sooty black. Below white, the colors somewhat mingled at the 

 line of demarkation at the level of the gape. Under tail-coverts white, 

 the lateral ones outwardly mottled with gray. Under wing-coverts white. 

 Axillars with subterminal dark gray bars and white tips. Wing 9 in. Tail 

 3^. Bill ly^. Tarsus l|f . Middle toe and claw 2^. 



The bird has been compared with a specimen from the Orkneys 

 in the American Museum, two from Wales and one from the 

 Bosphorus in the collection of Dr. Jonathan Dwight. The British 

 birds have the culmen slightly less than l| to Ij, tarsus l{| to Ijg. 

 middle toe and claw l| to 2. In the Bosphorus bird the culmen. 

 measures just over l|, tarsus l^f, middle toe and claw 2jg. 



This is doubtless the form recorded as anglorum breeding in the 

 Bermudas (Savile G. Reid. The Birds of the Bermudas, Zoologist, 

 Oct. and Nov., 1877, reprint 1883, p. 41). No bones of this species 

 were found with those referred to Mstrelata cahow, although mixed 

 with them were skulls and other bones clearly referable to P. 

 Iherminieri.
