 231, the a-ane, la grue, der KranicJi; dwells during the summer in the 

 high north and in the east of Europe; migrates in large troops, formed 

 into a triangle ; their passage over the Mediterranean sea attracted the 

 notice of the ancients, whose writings often make mention of it; — Grus

 Africa, Grus pavonina, Ardea pavonina L., Edwards Birds, Tab. 192, 

 Dictionn. univ. d'Hist. nat., Ois. PI. 9, fig. 2, has a much shorter bill than 

 the other species, as also distinguished from this in later times but very- 

 similar, Grus regulorum Lichtenst.' from South Africa, Buff. PL enl. 265.

 trompetter, Amsterdam, 1768, with a coloured figure. Less. Ornith. PI. 91, 

 fig. I, Cuv., R. Ani., ed. ill., Ois. PL 71, fig. 2; the A gaini ov caracara, 

 from Surinam and other countries of tropical South America. This bird 

 is very tame; it emits a peculiar dull sound, somewhat resembling the 

 cooing of doves, which seems to proceed from an air-sac. They bear some 

 resemblance to the gallinaceous birds, with which BuFFON united them, 

 in the short arched bill and the external appearance. Within the last few 

 years two very similar species, also from S. America, have been made known.
