Revised List of British Ophiuroidea. 135 



not for the white feathers at the base of the upper mandible 

 and the absence of the black collar, might be best described 

 as " a gigantic Sabine's Gull." Of it three specimens only 

 are known — one in Paris — the type; a second in the 

 British Museum from the Galapagos ; and a third from Peru 

 is in the rich collection of Gulls belonging to Mr Howard 

 Saunders. This, a bird of the year, is figured in the Pro- 

 ceedings of the Zoological Society for 1882, Plate xxxiv. 

 Nothing is known of its breeding haunts. 



In the list of occurrences of North American birds in Europe, 

 so carefully compiled by Mr J. J. Dalgleish, mention is made 

 of two species of North American Gulls as having been met 

 with in Great Britain, and it was to one of these, Bonaparte's 

 Gull {Larus Philadelphia, Ord.), that Mr Champneys' bird was 

 attributed, until I saw it at Mr M'CuUoch's shop in Glasgow. 

 As Bonaparte's Gull has most undoubtedly been met with in 

 Scotland, and as it bears a resemblance in many ways to 

 Sabine's Gull, I am not surprised at the mistake. I have 

 brought skins of this species for comparison. 



The other species is the Laughing Gull {Larus atricilla, 

 Linn.). It has been included in the British list on the 

 authority of Montagu, but recent writers are agreed that the 

 record is erroneous. 



The bird may always be known by its black primaries, the 

 knowledge of which fact might possibly be the means of the 

 bird being recognised, should it ever be killed on the British 

 coast.

No attempt appears to have been made to compile a com- 

 plete list of the Ophiuroids which frequent our seas, since 

 the Ptev. A. M. Norman published one nearly twenty years 

 ago ; ^ and since I have recently had the opportunity of ex- 

 amining the collections made by H.M.S. " Porcupine " and 



1 Ann, and Mag. Nat. Hist, ser. 3, vol. xv., pp. 104-115, 1865.
