Avifauna of Italy. 219 



in diflFereut stages of plumage — two from the neighbourhood 

 of Pisa, two from Massaciuccoli, one from Spezia, another 

 from MontepulcianOj and the Jast from Barletta. 



Gelastes genei (Breme). 



Our collection contains four specimens of this beautiful 

 Gull — one an adult male, richly tinted with rose-colour ; all 

 are from Cagliari. I have seen specimens of this species in 

 most Sicilian museums. 



iZ-E/ISSA TRIDACTYLA (Linu.). 



As Salvadori rightly observes, this is a rare bird with us ; 

 and yet I have succeeded in securing no less than six speci- 

 mens — one an adult male caught near Lucignano, in Val di 

 Chiana, Tuscany, on the 25th of February 1879. The others 

 are from Pinasca (Pinerolo) , Portoferraio (Elba), Genoa, and 

 Bari. 



Larus audouini, Payraud. 



Our collection contains four specimens of this rare and 

 interesting Gull, and three eggs. The specimens are all 

 fully adult. The first was shot in March 1877 in the Gulf of 

 Palmas (Sardinia) ; it is a male ; the two next, male and 

 female, on the island of Vacca (Sardinia) on the 4th of May 

 1878 j the eggs were collected on that occasion ; the last was 

 shot at Portoferraio (Elba) on the 30th of January 1879, 

 and is a female. These are the only specimens I have seen 

 in our Italian museums ; the one quoted by Salvadori as in 

 the Genoa Civic Museum is merely an adult Larus canus. 



Larus cachinnans. Pall. 



An abundant species. The adults in all seasons have the 

 head and neck pure white without any trace of brown specks, 

 and the legs and feet of a bright yellow. The young have 

 always flesh-coloured legs, and cannot possibly, I believe, be 

 distinguished from the young of L. argentatus. I have found 

 it breeding on the small islands of the Piombino channel and 

 at Gianutri ; it also breeds on the islands off Sardinia, and in 

 the Venetian lagoons.
