In addition to nearly all the species known to inhabit the 

 archipelago, examples of several more were obtained, some 

 seven or eighl; of which are new to science. 



Mr. Hartert will show you the type specimens of six new 

 species, of which I send you the descriptions. One species 

 is named after Mr. Frank Blake "Webster, who arranged and 

 sent out the expedition, and one after each of the collectors. 



Phalacrocorax harrisi, sp. n. 



This is the most remarkable discovery made during the 

 expedition. 



Adult : upperside brownish black, bases of feathers 

 blackish grey ; scapulars and wing-coverts dark hoary grey, 

 with black borders ; a number of white filaments scattered 

 about head and neck. Underside a mixture of pale brown 

 and grey ; tail black ; quills blackish brown, with greyish 

 tips on outer margin. 



This bird is the largest known Cormorant, being if any- 

 thing bigger than the extinct Ph. perspiciUatus, and its wings 

 are quite soft and incapable of flight, and of about the same 

 size as the wings of the Great Auk, Alca impennis. 



Wing of Ph. harri.n, 7 to 7'5 inches. 

 ,, Alca impennis, ^'7 inches. 



Hab. Narborough Island, Galapagos Islands. 



SULA WEBSTERI, Sp. U. 



Adult, in white plumage closely resembling S. piscatrix, 

 having the same hoary-grey on the primaries, but at once 

 distinguishable by its dark brownish-grey tail ; the bill is 

 also more slender, and the red at the base of the mandible is 

 more extended. Young in grey plumage somewhat variable, 

 very different from the young of S. piscatrix, being not so 

 dark above and the feathers of the back uniform brown, not 

 edged with light grey ; below darker than the young of 

 S. piscatrix. Size of S. piscatrix. 



Hah. Clarion Island, Galapagos, and the neighbouring 

 seas.
