Pelecanus, Lin. 



The Pelicans comprise all those in Avhich'the base of the bill is 

 found to have some part destitute of feathers. Their nostrils are 

 fissures, the apertures of which are scarcely perceptible. The skin 

 of their throat is more or less extensible, and their tongue very 

 small. Their thin gizzard, with their other stomachs, forms a large 

 sac. Their caeca are moderate or sif all. 



Pelecanus, Illig. Qnocrotalus, Briss.(l) 



The bill of the True Pelicans is very remarkable for its extreme 

 length, its straight, very broad and horizontally flattened form, for 

 the hook which terminates it, and for the lower mandible whose 

 flexible branches sustain a naked membrane, susceptible of being 

 dilated into a large sac. Two grooves extend along its length, in 

 which the nostrils are concealed. The circumference of the eye is 

 naked, and the tail round. 



P.onocrotalus, L.;Enl. 87; Edw. 92; Frisch, 186. (The Com- 

 mon Pelican.) As large as a Swan, entirely white, slightly tinged 

 with flesh colour; the hook of the bill of a cherry-red; is more 

 or less disseminated throughout the eastern continent, breeds 

 in marshes, and feeds exclusively on living Fish. It is said to 

 transport both food and water in its sac. The diff'erent changes 

 this bird undergoes from age are not sufficiently ascertained to 

 render certain the species of its genus that are enumerated. (2) 



Phalacrocorax, Briss. Carbo, Meyer. Halieus, Illig. 

 The Cormorants(3) have an elongated and compressed beak, the 



(1) Felecanus and Onocrotalus are two Greek names of this bird Latinized. 



(2) I see no difference between the Common Pelican and the Pelec. roseus, Son- 

 ner. Prem. Voy. pi. liv. As to the Pelec. manillensis. Id. LlII, Sonnerat himself 

 says he thinks it is the young of the roseus. Neither can I find any difference be- 

 tween the fusms, Edw. 93, and that of the Pi. Enl. 965, called roseus, but which is 

 much more hke the manilkiisis. Temminck thinks this figure represents the young 

 of the common species. T^e pUlippensis, Briss., VI, pi. Ivi, is the same specimen 

 from which the Pl- Enl. 965 was taken, so that both are the young of the onocrota- 

 lus. That of pl. 957, also called fmcus, appears fo be really a species identical 

 with that of Vieill. Gal. 276. Add the Pel. d lunettes {P. perspicillattis, T.) Col. 

 276. 



(3) Cormwant, from Cormorun, a com-aption of Corheau marin, on account of its 

 black colour. It is in fact the Aquatic Crow of Aristotle. Phalacrocorax (Bald 

 Crow) is the Greek name of this bird, indicated by Pliny, but is not employed by 

 Aristotle. That of Carbo is only used by Albert, who perhaps derived it from the 

 German name Scharb. To all these names Vieillot has added that of Hydrocorax, 

 Gal. 275.
