186 THE BIEDS OF DEVONSHIRE. 



under the name of 'Cuclde ' (Yarrell. B.B. IV. p. 22). 

 Mr. Rawson dissents from this view, but thinks 

 that a breeding colony may possibly be discovered 

 on the North Coast of Devon, Attention has been 

 drawn to what apparently must be considered a 

 dimorphic variation in colour of this Shearwater ; 

 regarding which the Rev. M. A. Mathew writes; 

 " Mr. Vaughan Davies of Skomer Island informed 

 me that the young Manx Shearwaters resembled 

 the adults in having white underparts, as you have 

 reported in this month's Zoologist. Every autumn 

 there are great numbers of the Manx Shearwater 

 in Torbay, and some years since I shot several 

 birds which had all the underparts a dark ash-gray. 

 At the time we endeavoured to make out that these 

 were Sooty Petrels, but they were unquestionably 

 only young Manx Shearwaters "(^?2/^^. Oct. 30. 1886). 



FORK-TAILED Y^T'BEL.—Oceanodroma Uucorrhoa (Vieill) 



An occasional, perhaps rare visitant, chiefly during 

 stormy weather during the last two months of the 

 year, when exhausted birds are occasionally found 

 on the North and South coasts of the County. 

 Mr. Brooking Rowe mentions a bird caught in the 

 middle of the town of Plymouth (Zool. 1866. p. 

 102). Mr. G. F. Mathew picked up another, dead 

 on Braunton Burrows; Mr. H. Nicholls has two 

 local specimens from the Kingsbridge district.
