evidence of local fishermen) that the " Cuervo marine " 

 appears in the winter oti" the small islets (Orn. Jahrb. 1913, 

 p. 189). 



When in Arrecife on the 16th of June, 1913, I examined 

 a stuffed specimen of the Cormorant in the collection of 

 Don Gonzalez which had been shot locally, and recorded it 

 in my report of the expedition (Ibis, 1914, p. 63). This 

 may be the same bird as von Thanner has recorded {supra). 



Range. The Cormorant inhabits the coasts of the north 

 Atlantic as far south as, and including tlie Mediterranean. 

 I doubt whether it is found much farther south than the 

 Straits of Gibraltar, though in winter a few wander appa- 

 rently as far as the Canary, Islands. Subspecies have been 

 described from Africa.

Sula bassana. The Gannet. 



Pelecanus bassamis Linn. Syst. Nat. 10th ed. 1758, p. 133 

 — Type locality : Scotland. 



The Gannet is an Occasional Visitor in winter, but some- 

 times, according to Meade-Waldo, is abundant round the 

 islands especially between Fuerteventura and Cape Juby on 

 the mainland (Ibis, 1893, p. 198). The same ol)server also 

 records a single bird seen off Fuerteventura on the 30th of 

 March, 1888 (Ibis, 1889, p. 508, and MS. diaries). 



Previous to this the Gannet had been observed only by 

 Bolle, who about the year 1853-4 handled immature 

 specimens in both the Binna and Leon collections in 

 Tenerife and Gran Canaria (J. f. O. 1857, p. 348). 



Polatzek says (Orn. Jahrb, 1909, p. 132) " the Gannet 

 appears very seldom," but I question whether he ever saw 

 the bird himself. 



Range. This well-known British bird, so familiar to every 

 voyager in the Bay of Biscay, extends its range in winter 

 down the north-west African coast (according to Hartlaub) 

 as far as Senegal. It is probably very rare south of the 

 Canary Islands,
