It is possible that all these species are subspecies of one or two type- 

 species. This point, however, can only be determined by future re- 

 searches. 



Genus Todirhamphus. 



I found in the collection of Lord Derby two new species belonging 

 to this genus. 



ToD. PECTORALIS. 



Green, with a white spot before the eye ; throat and chin dark ash- 

 grey ; next this with white on the crop ; breast light ash-grey ; the 

 inner margins of the wing-feathers and the inner wing-covers yellow ; 

 outer margins of the wing-feathers and tail olive ; belly and sides white. 



Head, 28 ; gape, 14 ; wing, 45 ; tail, 42 ; tarsus, 15 mm. long. 



Hab, 1 Mexico. 



Tod. ruficeps. 



"With red head and dark ash-grey occipital feathers ; next this an 

 ash-grey collar ; over part of the wings black, with two light yellow 

 bands ; wing- and tail-feathers with olive margins, which on the arm- 

 wings are more white ; lorum black ; ear-covers brownish ; chin and 

 throat white, with brownish tint, and divided from the yellow under 

 parts with a black striped band ; the tibial feathers black. 



Head, 26 ; gape, 13 ; wing, 46 ; tail, 36 ; tarsus, 17 mm. long. 



Hab. ? Mexico. 



Phrynorhamphus, Kaup. Smithomis, Ch. Bonap. 



The bill very broad, half as high as broad, with sharp culmen ; the 

 wings short ; the first wing-feather long, nearly as long as the seventh, 

 the second as long as the third and fourth ; outer toe at the base con- 

 nected with the middle toe. 



I am strongly inclined to believe that this section does not possess 

 the song-muscles. 



Phrynorhamphus capensis. Platyrhynchus capensis, A. Sm. 



Descr. — Upper mandible black, lower mandible yellow ; front and 

 lorum rufous yellow ; head black ; the bristle -feathers with white
