21. Phalacrocorax lucidus. 



22. sula fiber. 



23. Fregata aquila. 



This species nests on the rocks of the small island opposite 

 Sal Rei, which is the only place in the whole group where it 

 breeds. Generally flying at a great altitude^ the Frigate- 

 bird seldom approaches within shot ; on one occasion, how- 

 ever, we obtained a bird as it was engaged in chasing several 

 Gannets and attempting to rob them of their prey. 



24. Phcenicopterus roseus. 



A small colony breeds in the vicinity of some brackish 

 pools close to the sea and in the neighbourhood of Estengo 

 Velho. Breeding takes place about the middle of June, and 

 the eggs are laid on the bare ground. Two adult males 

 were obtained, 



25. Marmaronetta angustirostris. 



The Marbled Duck breeds in the vicinity of many of the 

 brackish pools on the island. We obtained three specimens, 

 two males and a female. In the latter the legs and feet 

 were of a distinctly greenish colour, instead of the dark 

 brown of those of the males. 



On May 21st we put into Tarrafal Bay, the principal 

 harbour of Santo Antao, The island is very mountainous 

 and possesses extremely fertile valleys. Sao Vicente depends 

 entirely upon it for produce. As regards its bird-life the 

 island calls for no special mention, since the resident species 

 are the same as those found on Sao Nicolau.
