matters worse, most of the birds collected there were thrown over- 

 board as lumbering the decks in some heavy weather on the night 

 after the visit ; and it is perhaps owing to this that no examples are 

 in the collection of CEstrelata arminjoniana and CE, trinitatis ob- 

 tained by the * Magenta's ' naturalists. 



1. Fregata AauiLA (Linn.) Frigate-bird. 



Two specimens, nos. 22 and 23, both females in immature plumage, 

 passing into the adult stage. As this plumage is rarely met with 

 and is little known, it is as well to describe it. The wings, back, 

 and tail are black, with a bar of old brown light-edged feathers 

 along the upper wing-coverts ; belly white ; flanks and under wing- 

 coverts black ; shoulders rusty black passing into chestnut, which 

 pervades the throat ; neck, nape, and crown of head white slightly 

 tinged with rust ; bill horn-white.

 Large numbers seen ; some deep black with scarlet pouch under the 

 throat. Found them sitting on the island."

2. SuLA piscATOR (Liuu.). 



No. 24, fully adult. Island of Trinidad, same date as above. 

 " These also were sitting." 



3. Phalacrocorax capensis (Sparrm.). 



No. 76, female immature. Simons Bay, Cape of Good Hope, 

 Oct. 2. 



No. 76a, adult. Same time and place. 



4. PhaSthon flavirostris, Brandt. 



No. 1 00, female, nearly adult. " Shot hovering round masts," 

 Oct. 29, lat. 23° S., long. 59° 18' W. 



5. GyGIS CANDIDA (Gm.). 



No. 28, female. Island of Trinidad, Aug. 21. "Breeding. Iris 

 black." There is a fine illustration of this beautiful species in 

 Gould's 'Birds of Australia,' vii. pi. 30. 



6. Sterna macrura, Naum. Arctic Tern. 



No. 95, male. Oct. 23, lat. 32° S., long. 57° 18' E. " Flew on 

 board in the night, commencement of S.E. monsoon." 



This specimen is an adult with full black head, excepting on the 

 forehead, where the feathers are white, as usual in autumn. It belongs 

 certainly to this species, which I have also had on one occasion from 

 the Cape of Good Hope ; but this is yet more south and east for its 

 range. It might have been expected that S. virgata or S. vittatay 

 both inhabitants of the islands of the Southern Ocean, would have
