342. Larus ridihundus L. Brown-Jieaded Gull. 



A few pairs bred in 1881 and 1882, in a marshy field by the River 

 Aire, just outside the Leeds borough boundary, and in 1883 they 

 bred in some numbers on Strensall Common, but their eggs, about 

 forty in number, were taken. The discussion in various numbers 

 of the " Field " for February and March, 1884, has added nothing 

 to the information which was in our possession at the time ot 

 framing our original account. 



352. Larus leucopterus, Faber. Iceland Gull. 



Additional occurrence : Spurn, a mature female and a bird of the 

 year, shot December, 1882, now in Clarke's possession. 



359. Procellaria leucorrJioa, Yieill. LeacJi's Petrel. 



Additional occurrences : Riplingham, near Beverley, one in 

 December, 1881, (Dobree, Nat., 1882, p. 100); Whitby, one 

 obtained near, in the possession of Mr. C. Bagnall (Stephenson). 



362. Puffims griseus (Gm.) Sooty Shearwater. 



At the time of publishing the Handbook, we were unable to 

 discriminate between the records of P. griseus and P. major. 

 We can now give the following occurrences of this species : — 

 Whitby, one shot in September, 1870, now in the museum 

 (Stephenson). One shot in Bridlington Bay, 1872, by Mr. 

 Elton, is referred to this species (Macpherson, Zool., 1883, p. 121). 

 Clarke examined a fine pair in September last, which had been 

 shot at Flamborough. Redcar, one shot September 17th, 1883 

 (Nelson, Zool., April, 1884, p. 147.) This species is not, how- 

 ever, new to the Yorkshire faun a, as Mr. Nelson supposes (see 

 Handbook, p. 85).
