SHEARWATER PETRELS. 403 



Gen. PuffinuSj Kay 



Beak like the last, but longer and not so thick; the 

 nasal tube is double, and does not extend nearly so far 

 along the back of the upper mandible as in the last ; in 

 both the hind toe is nothing more than a small pointed 

 claw ; tail with twelve feathers ; colour dark brown. 



243. PUFFINUS ANGLOEUM, Kay. Mindre Liran. Manx 



Shearwater. D. 



Upper parts black in the old birds, brown-grey in 

 the young; under parts white; tail rounded, about 

 equal with wings ; length 14 in. ; beak, from the fore- 

 head 1 in 4 1. ; tarsus 1 in. 6 1. ; beak black ; legs black- 

 brown; web flesh-coloured; eye brown. 

 Is only accidental in these seas.

water. 



Grey-brown above, much lighter than in the last; 

 below white; tail rounded; length 20 in.; beak, from 

 forehead, 1 in. 7 1. ; tarsus 2 in. 2 1. 

 There is a great question if this bird can be included 

 in the Scandinavian fauna ; at any rate it is only very ac- 

 cidental. 



Gen. Thalassidroma } Yig. 



Beak very thin, shorter than the head; of the same 

 form as the last; nasal tube single; wings long; second 

 feather longest; tail with twelve feathers; the smallest 

 web-footed birds in the world ; principal colour black. 



245. THALASSIDEOMA PELAGICA, Vig. Lilla Storm Svala. The 



Stormy Petrel. D. 



Black all over, with a white rump; tail square; 



sometimes a whitish streak on the wings ; length 6 in ; 



beak, from the gape, 4 1. ; tail \ in. shorter than the 



wings ; beak, legs, and claws, black. 



I do not think it has been detected breeding on any
