throat and breast pale claret-red, rest of lower parts deep black, 

 spotted next the breast and on the sides with large pearl-like

Total length 4| inches ; beak to gape 5^ lines, to front 5 lines ; 

 width 2^ lines, height 3 lines; wing 2 inches 1 line; medial

FRINGILLIDiE, TANAGRIN^. 



Tachyphonus saucius, Strickl. 



T. corpore toto atro-chalybeo, tectricibus alarum supemis minoribus 

 juxta humerum albis, juxta carpum sanguineis, infernis omnibus 

 albis. Rostrum nigrum, mandibula medio alba, pedes nigri. 



Allied to Tachyphonus nigerrimuSj Gm., but differs in the 

 smaller size, shorter beak, and sanguineous spot near the carpus. 

 I presume it to inhabit Columbia or Central America. 



Entirely black, with a purplish gloss, except the lesser wing- 

 covers next the humerus, which are white and pass into bright 

 orange-red as they approach the carpus. Lower wing-covers 

 white. Beak black, middle of lower mandible whitish; legs 

 black. 



Total length 5^ inches ; beak to gape 7 lines, to front 6 lines ; 

 wing 2| inches ; medial rectrices 2 J inches, external 2^ inches ; 

 tarsus 9 hues. 



Tachyphonus ruficeps, Strickl. 



T. fronte, mento summo, loris, oculorumque ambitu nigris, capite 

 toto reliquo gulaque intense rufo-castaneis, corpore toto plumbeo- 

 cinerascenti, alis caudaque obscurioribus. Rostrum nigro-cine- 

 reum, tomiis albidis, pedes brunnei. 



The upper mandible is smaller than the lower, somewhat like 

 that of an Emherizaj but the culmen is more arched. It agrees 

 however sufficiently with the structure of Tachyphonus quadri- 

 color, Vieill. (T. auricapillus, Spix) to warrant its collocation in 

 the same 'genus. I am unacquainted with the habitat. 



Front, lores, upper chin and circuit of eyes black ; head, cheeks 

 and throat deep chestnut-red ; rest of plumage leaden gray, pass- 

 ing to fuscous on the wings and tail. Beak blackish, margins of 

 mandibles whitish ; legs brown. 



Total length 5^ inches ; beak to gape 7 lines, to front 6 lines ; 

 wings 2i inches ; medial rectrices %^ inches, external 2^ inches ; 

 tarsus 10 lines. 



Calliste thalassina, Strickl. 

 C. capite cyaneo, loris et oculorum ambitu nigris, mento summo
