 a col. fig.), LATH. Synopsis i. PI. n., LESS. Ornith. PI. 3, fig. i, GUEBIN 

 Iconogr., Ois. PI. 3, fig. 4 ; the cere and the naked region round the eyes 

 yellow, back bluish-grey, thighs black, a crest of long, black feathers

 snakes, like Circaetus gallicus (see above p. 550) in Europe. 



Family LIV. Vulturince. Bill moderate, with culmen straight 

 at the base, constricted in front of cere, curved towards the tip; 

 upper mandible with margin sinuate, never dentigerous. Tarsi re- 

 ticulate with scales, sometimes hirsute or semi-hirsute. Middle toe 

 much longer than lateral toes; outer toes conjoined at the base by 

 membrane. Claws slightly curved, obtuse. (In most the head and 

 upper part of neck are naked or beset with scattered plumules. 

 Eyes surrounded by the flattened face, not placed in a depression 

 under exsert plumes.)

 der Lammergeier, der Geieradler; this bird lives on lofty mountains, 

 especially of the South of Europe and West of Asia. It feeds chiefly on 

 goats, lambs and chamois, which it kills by casting them down from the 

 precipice ; the feet are not very strong, and less adapted for the seizing and 

 retaining of prey. It attains a length of nearly 4 feet, whilst it is 9 or 10 

 feet from tip to tip of wings. On the Pyrenees and in Sardinia a variety^ 

 constantly smaller, is met with (KUESTEB Isis, 1835, s. 209, SCHLEG. in 

 SUSEM. Vog. Eur. s. 19). More interesting appears to be the difference 

 which the African Lammergeier presents; in which the tarsi are not 

 destitute of feathers below. (Gypaetus meridionalis BLAS. and KEYSEBL.,

Gypohierax EUEPPELL, Racama GRAY. Bill shorter than head, 

 compressed, with culmen curved towards the tip, which is acute. 

 Nostrils vertical placed in the naked cere. Kegion at the base of
