The extinct species of Fnffinus here described is named 

 after Mr. Edward McGall, in recognition of his success in 

 obtaining this valuable collection of fossil bird-bones from 

 Bermuda. 



Puffinus parvus, sp. nov. 



Recent Epoch. 



(In tlie original memoir, the bones of this extinct species are figured on 

 pi. ix. figs. 43-45; pi. x. figs. 55-56; pis. xi., xiii. fig-s. 101, 107, 

 121, 122, and 123.) 



There is abundant evidence pointing to the fact of the 

 existence of a small Shearwater, now extinct, that formerly 

 was abundant in the Rermudan tubinarine assemblage of 

 birds. This evidence rests upon the occurrence in the 

 collections before me of many subfossil bones that belonged 

 to various individuals representing it. For example, in that 

 part of the collection belonging to the American Museum 

 of Natural History, at the time I was at work upon the 

 material, there were the following specimens, namely, a 

 cranium (more or less imperfect), an ulna, a radius, a carpo- 

 metacarpus, part of a sternum, four ossa innomiuata, a 

 femur, a tibio-tarsus, and a metatarsus; while in the 

 McGall collection I found five perfect humeri, three ulnae, a 

 radius, a carpo-metacarpns, a proximal joint of an index digit, 

 a coracoid, an inferior mandible, an imperfect os furculum, a 

 tarso-metatarsus, an os innorainatum of the left side; sub- 

 sequently, there also came to light an impeifect cranium. 

 All of this material is described in great detail in my 

 memoir, and I have compared it, character for character, 

 with the bones of skeletons of all the Shearwaters and other 

 forms that I could bring together from private and public 

 collections in America and England. 



These bones belonged to a Shearwater (Puffinus) smaller 

 than Audubon's Shearwater [Puffinus Ihenninieri) — that is, 

 smaller than any Shearwater in our present Atlantic Ocean
