102 On three new Genera or sub-Genera of Thrushes. [Fbb, 



2nd Species. Flaviventer ; yellow-bellied, nobis. Above, grass 

 green : below, full yellow : mask covering the face and ears, bright 

 chestnut : bill, dusky above, fleshy below : legs, fleshy white : iris 

 brown : size of the last : sexes alike. 



3rd Species. Albiventer, nobis. Above, olive brown, dotted with 

 buff: below, white, each plume being largely marked in the centre 

 with dusky-brown: bill, dusky horn with a fleshv base: legs, brown : 

 iris, brown : 4| inches by 7^, and % oz. in weight : tarsi rather lower 

 and stouter, and bill rather stouter than in the preceding species, 

 which are the typical ones. 



4th Species. Rufiventer, nobis. Above, olive brown, as in the 

 last, but less dotted : below, rufous picked out with dusky, as in Al- 

 biventer : legs, fleshy brown : bill dusky horn : iris, brown : size of 

 the last, from which this species differs only (but permanently) by 

 the ruddy ground color of the inferior surface. 



Remark. Tiiese little birds have a very strong muscular stomach, 

 and feed on hard grass seeds and hard minute insects. They pro- 

 cure their food entirely on the ground, and live in woods exclusively. 

 They are almost equally common in the central and lower hilly 

 regions : in the northern I have not found them. 



Ckateropodin^e. Genus Larvivora, nobis. 



Bill equal to head, subcylindric, straight and slender ; at base 

 rather broader than high, and gradually narrowed ; ridge consider- 

 ably keeled : upper mandible rather longer than the lower, and 

 vaguely inclined and notched. 



Rictal and nuchal hairs small and feeble. Wings, tail, and nares 

 as in Turdus, but the two former somewhat less developed. 



Tarsi elevate, slender, nearly smooth : toes, all of them, compress- 

 ed ; lateral fores and hind sub-equal ; exterior fore connected to 

 the first joint. Nails, moderately arched and rather acute. 



1st Species. L. Cyana ; blue Larvivora, nobis. Above, full blue : 

 below, bright rusty, paler and albescent towards the vent and under 

 tail-coverts : thighs, blue with white cross bars : cheeks, black : su- 

 perciliary line, white : bill, dusky horn : legs, fleshy grey : iris, 

 brown : 6 inches long by 9\ wide, and \\ oz. in weight: sexes alike. 



2nd Species. L. Brunnea ; brown Larvivora, nobis. Above, brown : 

 cheeks and sides, rusty: below, white: bill, dusky horn : legs, fleshy 

 grey ; iris, brown : sexes alike : size of the last. 



Remark. These birds differ conspicuously from Tesia (Swainson's 

 Aipunemia ?) by stronger wings and tail, by their less cylindric and 

 less entire bill, and by their open meruline nares. They have much 

 of the aspect of the Sylviadce, but are essentially terrestrial. Do they 

 not constitute the oriental type of the American Drymophilce ? and do
