A. St. Iago, Cape-Verds (July 1873). 



Four examples of the peculiar King-hunter of this Island, Halcyon 

 erythrogastra (Temm.), Sharpe's Kingf. p. 171, pi. 63, were 

 obtained here. In one specimen the eyes are marked " black," and 

 the contents of the stomach " insects." 



B. Tristan-oV Acunha group (October 1873). 



Seven examples of the peculiar Thrush of Tristan d' Acunha, de- 

 scribed by Mr. Gould, P. Z. S. 1855, p. 165, as Nesocichla eremita, 

 were obtained. The sexes are not marked ; but the specimens are all 

 nearly alike, so that probably the sexes do not differ in plumage. The 

 irides are noted as " black." 



In the adjoining island "Inaccessible," five specimens of the 

 peculiar Finch lately described by Dr. Cabanis (Journ. f. Orn. 1873, 

 p. 154) as Nesospiza acunhce were obtained. All five are alike ; 

 the eyes are marked "hazel; " but the sexes are not recorded. 



Of Crithagra insularis, described by Dr. Cabanis at the same 

 time as the Nesospiza, there is no specimen in the collection, nor of 

 the Island-Hen (Gallinula nesiotis, Sclater, P. Z. S. 1861, p. 261). 

 The latter is said to be now almost extinct 1 . 



The only oceanic birds in the collection from the Tristan-d'Acunha 

 group are two Petrels, Pelagodroma marina and (Estrelata mollis, 

 both from Nightingale Island, the most southern of the three islands 

 of the group, and one Penguin {Eudyptes chrysocome) from Inac- 

 cessible ; but Sir Wyville Thomson (Atl. ii. pp. 164, 178) mentions 

 several others. 



C. Kerguelen Land (January 1874). 

 The only land-birds from Kerguelen Land in the collection are
