Besides these species from South America, there are some also from Africa, 

 as Capiio Vaillantii Gray, Pims cafer Gm., Micropogon sulfuratus De la 

 Fresnaye, Guer. Mag. de Zool. 1836, Ois. PI. 60;— Capita margariticus 

 Gray, Micropogon margaritatus Temm., PL col. 490, &c. These last 

 si^ecies form the genus Trachyphonus Eanzani, Bonap. 



Bucco L., Tamatia Cuv., Ca^jito Temm. (not Vieill.). Bill 

 moderate or long, strong, compressed towards the tip; upper man- 

 dible hooked, produced beyond the lower. Inferior margin of lower 

 mandible long, convex, ascending. Gape ample. Nostrils placed 

 in the base of bill, covered with recumbent plumes and setae. Tarsi 

 short. Tail rounded or even, moderate, or somewhat long. Wings 

 with fourth quill longest. 



Sp. Bucco Tamatia Gm., Buff. PI. enl. .746, fig. i, Cuv. R. Ani., id. ill., 

 Ois. PI. 52, fig. i;— Bucco collaris Lath., Bucco capensis L., Buff. PI. 

 enl. 395 Guer. Iconogr., Ois. PI. 34, fig. 4 (Linn^us' name cannot be 

 preserved, since this species, like all the others of this genus, belongs to 

 South America) ; — Bucco macrorhynchus Gm., Buff. PI. enl. 689, Lesson 

 Ornitk. PI. 24, fig. 2 (under the incorrect name of Tamatia melanoleuca), 

 &c. These species ought, with systematic zoologists, to retain the name 

 Bucco, since B. cap>eims is the only species which, in the system of Ltn- 

 N^us, is brought forward under this generic name. They have not always 

 ten tail-feathers; some have twelve, as B. macrorhynchus. The brown 

 species in particular have some resemblance to Dacelo Leach, a genus of 

 the Halcyons living in the woods of the eastern hemisphere. 



Chelidoptera GouLD, Brachypetes SwAiNS. Bill short, curved, 

 compressed, with tip acute. Tail short. Wings long, with second 

 quill longest. 



Sp. Chelidoptera tenebrosa Gray, Monasa tenehrio Temm., PI. col. 323, fig. r ; 

 Guiana. Cuculus tenehrosus Gm., Buff. PI. enl. 505, is refeiTed to this 

 species, which in that case is drawn with too long a tail, and incorrectly 

 with yellow legs (in place of black). 



Monasa ViEiLL., Less., Gray, Lypornix Wagl. Bill some- 

 what long, with tip of both mandibles bent. Wings with fourth 

 and fifth quills longest of all. Tail elongate, broad, with 12 

 feathers. 



Sp. Monasa franquilla Vieill., Cuculus tranquillas Gm., Buff. PI. enl. 512, 

 Less. Ornith. PI. 22, fig. 2; black, with orange-coloured bill; Guiana. — 

 Monasa {Lypornix) ruficax>illa Tschudi Faun, peruan. Tab. 24, fig. i, &c. 

 As in the two preceding genera all the known species of this genus occur 

 in South America only.
