The author confirms the observations of Prof. Owen (P. Z. S. 
1835, pp. 9-12) as to the communication existing between the 
lungs and the subcutaneous air-cells in some of the Pelecanid<By 
which had been denied by Messrs. Natalis Guillot (Ann. Sc. 
Nat. 2 ser. 1816, v. p. 25) and Sappey (Recherches sur Pappareil 
respiratoire des Ois. pp. 70-80).

The specimen was found on Punk Island, near Newfoundland 
(P. Z. S. 1863, pp. 435-438)’; being defective in the bones of the 
extremities, the author procured specimens of these from Mr. 
John Hancock, and, thus having at command the materials for a 
description of the complete osteology of the bird, he proceeds to 
give an account of it, entering into very minute details of every 
bone, and finally comparing the skeleton with that of other 
diving birds, especially that of Uria {Cepphm) grylle and Aptc- 
nodytes antarcticus. With the latter, as might have been ex- 
pected, Alca impennis has no affinity. It has twenty-two free 
vertebrje between the skull and sacrum, while A. tor da has one 
less. The plates appended to this valuable paper serve very in- 
sufficiently to illustrate it.

a well-developed urinary-bladder.

The author by way of introduction states his concurrence in 
the views of many modern systernatists as to the high position 
occupied by the Psittaciy and then proceeds to describe in detail 
the cranium of the species under consideration, and subsequently, 
but more briefly, its sternal apparatus. 
The sternum of Phlogcenas crinigera is described and figured.
