306. (308) Hydrochelidon leucoptera (Temm.) . The White- 

 winged Black Tern. 



Local name : Cirlewwa tar-rebbigha. 



This species occurs on passage during both seasons, but 

 seeras to be more common during the spring. I have seen 

 individuals also during the summer, but consider such occur- 

 rences as unquestionably rare. The local name Avas given 

 to me by Mr. Micallef, who stated that he had known the 

 species always by that name. 



307. (314) Sterna anglica anglica Mont. Gull-billed Tern. 

 Local name : Cirlewwa taV Itvjhilterra. 



The first mention of this species in Malta Avas made by 

 Wright, who, in the second appendix to his list, records 

 three specimens in the adult breeding-plumage killed in 

 May 1864. I have seen a specimen mounted by Mr. G. 

 Debono, of Musta, and shot by him in the spring, and 

 have one in my collection presented to me by the same 

 gentleman, who shot it at the Saliua on the 16th of April, 

 1914. 



308. (313) Sterna caspia Pall. The Caspian Tern. 

 Local name : Cirlewiva prima. 



In the fourth appendix to his list Wright records a 

 specimen shot by him near Fort Manoel on the 21st of May, 

 J 869, and states that he had been informed of the capture 

 of another at the same time. I have seen three specimens 

 in Mr. Micallef^s collection; these were shot at the Salina 

 in the spring of 1901. Giglioli gives ^^ Cirlewiva'' as 

 the local name for this species ; but this is only a generic 

 name. 



309. (312) Sterna sandvicensis sandvicensis Lath. The 

 Sandwich Tern. 



Local name : Cirlewiva hamra. 



Schembri says that flocks of these birds are seen here 

 annually at the approach of winter. According to Wright, 

 a few are at times noticed during both autumn and winter.
