The group " Buccones " of this author, who may have caught a spirit of retrograde classifi- 

 cation from the Director of the Leyden Museum, consists of the two very distinct families of 

 Oapitonidce and Bucconidce, — the distinction between which, however, is recognized by the 

 primary division of the group into two, according as the rectrices are 10 (Capitonidce) or 12 

 (BvAiconidce) in number; equivalent respectively to the "scansorial" and "fissirostral" 

 Barbets. Of the former are treated 11 spp. of Pogonorhynehus, 34 of Megalaima, 1 Tetragon- 

 ops, 11 of Capita, and 1 Calorhamphus. Of the latter are given 11 spp. of Bucco, 4 of Mala- 

 coptila, ^ of Monasa, and 1 of Ohelidoptera. The groups are, together, represented by 300 

 specimens in the Leyden Museum. Various species, not represented in the Collection, are 

 also treated in the foot-notes.
