RESUME OF THE HISTORY. xy {[ 
1840. Mr. G. E. Gray (Gen. of Birds, ii. p. 428), in his magnificent work on the Genera 
Birds ’ S lves a vel T com prehensive account of this group; and at the time he wrote the 
major, ty of the species were well known. He joins them to the Piaidw, making them the 
hrst subfamily and naming them Capitonhm from Capita of Vieillot, the oldest generic name 
which rightly belongs to this family. They are immediately followed by the PiewmnintB, 
through which they are supposed to be allied to the Picidce. Mr. Gray divides them into 
five genera:— 1st, Laimodon , a name substituted for Pogonias (Illiger), but which must yield 
precedence to Pogonorhynchus (Van der Hoeven) ; of these he enumerates ten species. 2nd 
egalarma, substituted for Bucco of the older authors, for the Asiatic group ; this name, with 
a slight collection in the spelling, is the name at present in use. Under this head are 
tu enty -nine species, twenty-one of which properly belong to this genus, three are synonyms 
or untraceable, the others have since been separated into other genera. 3rd, Capita includes 
a the Capitonince then known, except Caloramphus. 4th, Caloramphus. 5th, Psilopogon, 
is mtioduction of Megalcema makes the seventh genus as now accepted. 
1850. Bonaparte reverts to the name Bucconince for this family, and places them 
between the Picumnince and the Puff-birds, which he terms Capitonince ; he divides them 
m the ioilowmg manner, introducing several new genera 
E Gymnobucco (n. g.), type G. calvus. 
2. Psilopogon. 
3. Psilopits. 
4. Xylobucco (n. g.), type X scolopaceus. 
5 . Trachyphonus. 
6. Micropogon. 
7. Eubucco (n. g.), type E. bourcieri. 
8. Bucco, type M. virens.
