The carotid arteries in Bucorvus^ instead of meeting and. running to- 
gether, course up the sides of the neck in company with the pneumo- 
gastric nerves and jugular veins of their respective sides as they do in 
Mammals, but in no other Birds, so far as the author is aware. Bu- 
corvus differs from Buceros and Toccus in wanting the accessory 
femoro-caudal muscle. Other points in the anatomy of this bird are 
described. 
. On the Anatomy of Chauna derbiana and on the Systematic 
Position of the Screamers {Falamedeidce). Tom. cit. pp. 189-200. 
In this paper, the anatomy of Chauna is examined with reference to 
the following points : Cutaneous system, with pterylosis, alimentary 
canal, respiratory organs, myology, as regards the following characters : 
— 1. The presence or absence of the expansor secundariorum muscle. 
2. The presence or absence of a special muscular slit from the biceps 
humeri, to the patagium. 3. The area of origin of the obturator inter- 
nus. 4. The degree of development of the tensor-cruris fascias. Then 
follows an examination of the osseous system. The author differs 
from Parker and Huxley in his views of the systematic position of 
the Falamedeidce, and contends that the Screamers cannot be placed 
amongst the Anserine birds. He considers that this family occu- 
pies an independent position, and that it sprang from the primary 
avian type at about the same time as most of the other important 
families. Four plates illustrate the paper, on which are depicted views 
of the proventriculus and gizzard, the windpipe, the myological points 
dwelt upon in the paper, and the coeca. Woodcuts give the posterior 
aspect of the skull in Chauna, Cereopsis, and Crax, and the under sur- 
face of the skull of Chauna. 
. On the Anatomy of Aramus scolopaceus. Tom. cit. pp. 275-277. 
Some points in the structure of the skull (woodcuts of which are 
given) of Aramus are described in this paper, as are also the trachea, 
the myology of the leg, and the characters of the alimentary canal. 
The systematic position of Aramus is pronounced to be near Crus, and 
not distant from Ibis, Flatalia, and JEurypyga. 
, Notes on the Anatomy of Flotus anhinga. Tom. cit. pp. 
335-345. 
Several points in the anatomy oi Flotus are here described, the pecu- 
liarity of the position of certain cervical vertebrae and the muscles in 
connection therewith being specially examined, as also the presence in the 
stomach of a highly peculiar hairy mass, serving to sift the food as it
