-/■ 238. Sterna anglica. 



Salvadori mentions having received two specimens from 

 Sardinia, that were killed there in May 1868. Two others, 

 killed at the same time, were presented to the museum at 

 Cagliari. 



239. Sterna cantiaca. 



Very common, and breeds in the island. 



240. Sterna fluviatilis. 



Common in summer. 1 am not sure that any remain 

 during winter. 



241. Sterna minuta. 



A small flock passed over my head one day early in May 

 near St. Antioco, the only time I ever saw them. " They

242. Hydrochelidon leucoptera. 

 Passes in spring, but is not common. 



243. Hydrochelidon fissipes. 

 Not uncommon during summer. 



-> 244. Larus minutus. 



Found at all seasons, but not numerous. 



245. Larus melanocephalus.

 tips of their primaries were pure white ; after that date along 

 the coast of Genoa and Leghorn, where they are extremely 

 numerous, few are to be seen in their winter dress. 



On one occasion I saw a pair commit an atrocious piece of 

 cruelty on an unfortunate small bird (a Wagtail, 1 think, by 

 its flight), which was vainly trying to overtake the steamer, 

 evidently nearly exhausted, having only sufficient strength 

 left to clear the waves. It was at once seen by a pair of 

 these Gulls that were hovering hungrily round the stern, 

 and they immediately gave chase. After one or two unsuc- 

 cessful swoops pluckily and skilfully evaded by the Wagtail,
