Shufeldt: Birds from Bermuda. 385 



and duly counted, there remained quite an extensive collection of 

 bones which, upon comparison with the corresponding ones in the 

 collection as a whole — that is, with all the material that ever came 

 before me from the Bermuda caves, both main lots — proved to be, 

 beyond all doubt, those of Pnffimts parvus. These bones further 

 agree, in their morphology, lengths, and general proportions, with the 

 type bones of this extinct Shearwater, as figured and described in the 

 body of the present memoir. In this lot there are found : 



4 skulls (adults), pterygoids and quadrates missing; the basal, 



frailer parts broken off and lost. (No mandibles accompany 

 them.) Otherwise quite perfect. 



(In the large collection of vertebra: listed above there may be, 

 and probably are, some that belonged to this small Shearwater. 

 This applies to other small bones, as toe-joints, finger-joints, 

 etc.) 



5 sternums ; more or less perfect. 



4 coracoids ; i right and 3 lefts. 



5 scapulae ; 2 rights and 3 lefts. 



2 OS furculse (perfect) ; 4 fragments of others. 

 13 humeri ; 4 rights, 9 lefts. 

 10 radii (rights and lefts) ; some quite perfect. 



9 ulnae; three rights and 6 lefts. 



6 carpo-metacarpi ; 2 rights, 4 lefts. 

 4 femora ; i right. 3 lefts. 



9 tibio-tarsi ; 3 rights, 6 lefts. All quite perfect ; in fact, all the 

 limb-bones are in an excellent state of preservation, and the 

 majority of them perfect. 



7 tarso-metatarsi ; 5 rights, 2 lefts. 



Finally, the collection contains the imperfect sternum of a very 

 small species of Shearwater (Pnffimts), smaller than Audubon's 

 Shearwater. It is more than likely that this bone belonged to an 

 adult specimen of Pnffinus parvus Shuf. The antero-superior portion 

 is broken off and lost; otherwise the bone is quite perfect. 



Conclusions. 



There is but little to be said under this head. The creation of the 

 new species, Pnffimts mcgalli and P. parvus, is amply justified, based.
