but is often eaten by the poor, as are the young. Neither 

 this nor the other species fly under water, but propel them- 

 selves by synchronous beats of the feet, with amazing speed. 

 Both may be tamed, but this less easily than the other. Their 

 affection for their young is very great. 



This being certainly Pelecanus Graculus of Linnaeus and 

 Latham, I see no reason for changing the name to cristatus, 

 and transferring it to another species.

GENUS CXLY. SULA. GANNET. 



The Gannets, of which one species occurs on our coasts, 

 are organized for plunging from a height upon their finned 

 prey, and are thus physiologically out of place among the 

 Divers. In fact one half of the family of the Pelecanina? 

 belongs to the Urinatrices, and the other to the Mersatrices. 



In the genus Sula, the body is of moderate bulk, rather 

 elongated ; the neck of moderate length, and very thick ; 

 the head large. Bill longer than the head, opening beyond 

 the eyes, straight, elongated, conical, moderately compressed ; 

 upper mandible with the ridge very broad, convex, separated 

 by grooves from the sides, which are slightly convex and 

 perpendicular, with a slender jointed additional piece be- 

 neath the eye, the edges sharp, direct, irregularly jagged with 

 numerous incisions directed backwards, the tip a little de- 

 curved, and rather acute ; lower mandible with the angle 

 extremely long and narrow, the sides erect and convex, the 

 edges sharp and serrated, the tip compressed and acute. 

 There is a small gular sac, of which a part is bare. Mouth 

 wide, pale, flat, ridged ; tongue extremely small, blunt ; 

 oesophagus extremely wide, much dilated below ; pro ventri- 

 cular glands forming a broad belt, partially divided ; stomach 

 extremely small and thin ; intestine of moderate length, 

 slender ; coeca very small. Nostrils obliterated in the adult, 

 open in the young. Eyes rather small, surrounded and 

 preceded by a bare space. Apertures of ears small. Feet 

 short, placed rather far behind; tibia? concealed by the
