SLENDER-BILLED GULL. 99 



Two instances are related of its having been seen 

 by M. Cantraine in Sicily, and the following is copied 

 from the "Faune Meridionale" of M. Crespon: — "AVhen 

 the ornithology of the Gard appeared, I first made 

 known that this new species was found in France. 

 Temminck had only previously received two skins 

 from Italy. But in the spring of 1842 I had brought 

 to me five of the same bird, which had been captured 

 on the borders of the sea. I saw at a glance that 

 two of the females had already begun to sit, and I

 and it was not without trouble that I found some 

 ashy spots, as though they had been effaced. There 

 were some individuals of this species of Gull flying 

 about the spot." 



The description of M. Crespon, says Degland, of the 

 eggs of this bird, "agrees with that which M. Moquin- 

 Tandon gave to me; according to whom they would 

 be of a dirty white with dark grey and brown black 

 spots. Great diameter five centimetres four millemetres, 

 small diameter three centimetres eight millemetres." 



Dr. E. Baldamus ("Naumannia," 1853, p. 419, et seq.) 

 has the following remarks: — "These eggs differ at a 

 glance from all other Gulls' eggs, in having one
