Tenia, Vaill.(1) 
The tail and carriage of the Pies, with an elevated beak, whose 
upper mandible is arched, the base furnished with velvet feathers 
almost like the Birds of Paradise. 
The most anciently known, Corvus varians, Lath.; Vaill. Afr. 
563 Vieill. Gal. 106, is of a bronze green. It is found in Africa 
and in India.(2) ‘ 
Gravcopis, Forster.(3) 
The same beak and carriage, but there are two fleshy caruncles 
under the base of the former. 
The species known, Glaucopis cinerea, Lath. Syn. I, pl. xiv, 
is from New Holland, and is the size of a Pie; blackish, with a 
cuneiform tail. It feeds on insects and berries, and perches but 
seldom. Its flesh is highly esteemed. ; 
Coracias, Lin.(4) 
. 
The rollers have a strong beak, compressed near the point, which . 
isa little hooked. The nostrils are oblong, placed at the edge of 
the feathers, but without being covered by them; the feet short and 
stout. They belong to the eastern continent, and are like the Jays 
in their habits and in the loose feathers on the forehead. Their co- 
lours are vivid, but rarely harmonious. Some peculiarities of their 
anatomy approximate them to the Kingfishers and Pies, such as two 
emarginations in their sternum,’a single pair of muscles to their 
inferior larynx, and a membranous stomach.(5) 
Tue Rotiers, properly so called, 
Have a straight beak, every where higher than wide. There is 
one in Europe. 
Coracias garrula, L.; Enl. 486. (The Common Roller.) Sea- 
green; back and scapulars fawn-coloured; pure blue on the tip 
of the wing; about the size of the Jay. It is a very wild bird, 
although sociable engugh with its fellows, noisy, nestles in the 
(1) Vieillot ii changed this name into Crrrsirra, Gal. 106; Horsfield into 
that of Purexorrrx. Temminck unites Temia with Gravcoris. 
(2) Add. Glaucopis leucoptera, Tem. Col. 285;—Gl. temnura, Id. Col. 337. 
(3) Bechstein substitutes the term Callaas for that of Glaucopis. 
(4) This name, consecrated by Linnzus, has been changed by Vieillot into that 
of Gatearus, which, among the ancient Latins, belonged to the Onole.
