Note. On some other sub-genera to be referred to Tyrannus or 

 Muscivora, omitted here, cons. GRAY Gener. (Muscicapince and Ty- 

 rannince) and CABANIS Archivfur Naturgesch. 1847, pp. 247 251. 



Platyrhynchus DESMAR., VIEILL. Bill short, depressed, equal- 

 ling the forehead in breadth, emarginate at the tip. Gape of mouth 

 produced below the eyes. Nostrils basal, superior. Long bristles 

 at the angle of mouth. Tarsi longer than middle toe ; outer toes 

 conjoined at the base. Wings with third, fourth and fifth quills 

 subequal, fourth and fifth longest of all. Tail short, even.

 fig. 2 _ Platyrhynchus cancromus TEMM. PL col. 12, fig. 2; Brasil, &c. 



Todus L. Bill moderate, subulate, depressed, with culmen dis- 

 tinct, with tip rounded and obtuse, surrounded at the base by large 

 bristles. Nostrils placed in back of bill before the base. Wings 

 short, with first two quills short, narrowed, fourth longest of all. 

 Outer toes united, free at the extremity only. Tail short, rounded. 



Sp. Todus vvridis L., BUFF. PI. enl. 585, figs, i, 2, VIEILL. Galer. PI. 124; 

 under this name, according to LAFKESNATE, two species are included ; one 

 of Jamaica, to which he would appropriate the name Todus viridis exclu- 

 sively, the other of St Domingo, Todus Dominicensis LAFRESN., to which 

 the figures referred to belong (Revue Zoologique par GUERIN, 1847, pp. 326 

 333)- Perhaps Todus subulatus GOULD (GRAY Gen. Tab. xxii.) is not 

 specifically different from this last. 



Triccus CABANIS, Todirostrum LESS. Bill somewhat short, 

 with tip hooked, emarginate. Tail cuneiform. (Other characters 

 nearly of the preceding genus, but outer toes less concrete.) 



Sp. Triccus cinereus, Todus cinereus L., BUFF. PL enl. 525, fig. 3; Triccus 

 diops, Muscicapa diops TEMMINCK, PL col. 144, fig. i, &c.

 Hapalocerus (Lepturus SWAINS.), Colopterus CABAN. 



On these genera conjoined with Todus, cons. CABANIS in TSCHUDI Fauna 

 Peruan., Ornith. pp. 163 166, and Archivf. Naturgesch. 1847, pp. 251 

 254. Colopterus is distinguished by the tail even, the tarsi somewhat 

 long and especially by the first three quill-feathers short and narrow. Sp. 

 Colopterus cristatus CABAN., Archivf. Naturg. 1. 1. Tab. v. fig. 2, &c. 



Fluvicola SWAINS., GRAY, Entomophagus MAXIM. (Add Xolmis 

 BOIE, CABAN., Tanioptera BONAP.) Bill moderate or shorter than 

 head, with culmen rounded, tip emarginate. Nostrils basal, lateral. 

 Tarsi longer than middle toe. Outer toes conjoined at the base.
