56S MR. O. SALVIN ON THE AVIPAUNA

Obs. (E. hmsitatm affinis, sed tectricibus supracaudalibus dorso concoloribus nee albis 

 distinguenda. 



There are two specimens of this species in the British Museum, both obtained by 

 Captain Kellett and Lieut. Wood in the Galapagos, one of them being labelled as 

 coming from Chatham Island. These skins differ from a mounted specimen of 

 (E. hcesitata in the British Museum, from Haiti, in having the upper tail-coverts of the 

 same colour as the back, and in the dark colour of the crown being connected with that 

 of the back by the feathers of the hind neck being tipped with the same dark colour. 

 There is no other species to which, so far as I am aware, this bird is at all nearly allied. 

 I have little doubt but this Petrel is the small "Albatross" spoken of by some of the 

 early visitors to these islands. 



Genus Spheniscus. 



The Penguins are restricted in their range to the southern hemisphere. The peculiar 

 species of the Galapagos has probably the most northern habitat of any member of the 

 family. Its nearest ally is S. magellanicus, from the Straits of Magellan and the 

 Falkland Islands.

Hab. James Island (SundevaU). 



The above description is the original one given by Professor Sundevall in the ' Pro- 

 ceedings ' for 1871. He there compares the species to S. demersus of South Africa; 

 but its relationship, so far as is indicated by the distribution and number of the dark and 

 white bands on the neck are concerned, show that it has greater affinity with S. magel- 

 lanicus of the Straits of Magellan and the Falkland Islands, where these marks, in a 

 more decided form, are quite similarly distributed, except that in the Galapagos bird 

 the chin is white. From *S'. magellanicus S. mendiculus differs in its longer and more 

 slender bill, three fourths of the base of which is yellow instead of black, and in its
