Sp. Oygnus olor GM., BUFF. PI. enl. 913, NAUM. Taf. 295, GU^RIN Iconogr., 

 Ois. PI. 66, fig. i ; the swan, le cygne, der Schwan, &c. The feathers on 

 the whole body are white ; the bill red with a black tip and black sides, 

 a tubercle at the fore part of the head. This species lives in lakes and 

 large ponds of the middle of Germany and in the east of Europe, and is 

 met with almost everywhere as a tame bird, especially in the basins and 

 ponds of many Dutch towns. The trachea in both sexes runs direct to 

 the lungs without curvatures. On the other hand the double curvature of 

 the trachea is remarkable in Anas Cygnus (ferus) L., BRISS. Orniih. VI. 

 Tab. 28, Cygnus xantkorhinus NAUM., Taf. 296, the wild swan, a species 

 which, with us, passes along the coast in winter, and is distinguished by 

 its black bill, yellow only at the base, and by the absence of the tubercle 

 on the forehead; this species broods in Lapland, Russia, Siberia, &c. 

 Cygnus BewicTdi YARR., Cygnus islandicus BREHM, Cygnus melanorhinus 

 NAUM. Taf. 297, smaller than the preceding; observed sometimes in Hol- 

 land in the winter. 



In New Holland there lives a black species with a red bill, Anas atrata 

 LATH., Anas plutonia SHAW, Cygne noir du Cap de Diemen, LABILLARDIERE 

 Voyage a la Reck, de LA PEYROUSE, Atlas, PI. 9, LESS. OrnitJi. PI. 117, 

 fig. i ; swans of this species may be seen in London in St James's Park. 



Family HI. Steganopodes ILLIG. Bill long or moderate. 

 "Wings adapted for flying, long or rather long. Feet short, tetra- 

 dactylous, with hallux placed internally and directed forwards, 

 joined by membrane to the inner toe. Tarsi reticulate, with scales 

 hexagonal. 



Pelecanus ILLIG., TEMM. (species from gen. Pelecanus L.). Bill 

 longer than head, broad, depressed, terminated by a hook. Nostrils 

 basal, linear, narrow. An unplumed region at the base of bill. 

 Lower mandible composed of two flexile branches, sustaining the 

 lax unfeathered skin of the throat. Tail rounded, short. 



The pelicans are large white birds, which live on fish, and occur in 

 various countries both of the old and new world. With LINN.EUS the 

 genus Pelecanus comprises almost all the species of this family; to the 

 genus, as limited by modern writers, only few species belong. On the 

 specific characters may be consulted, H. LICHTENSTEIN, in AWiandl. der 

 Alcad. zu Berlin, Physik. Kl. 1838, Beitr. z. ornith. Fauna von California 

 &c. s. 17 32. The skeleton of the pelican is distinguished by its many 

 hollow bones, its great pneumaticity. With the ancients the common 

 European species occurs as Onocrotalus (PLiNius) and IIeAe/ai>os (OPPIANUS), 

 whilst the birds named IleXe/capes by ARISTOTELES were probably Platalece, 

 but at least were certainly not the birds now named pelicans ; BRANDT
