Oreoperdix crudigularis, n. sp. 



Line round the eyes, above the ear-coverts, extending broader 

 across throat, black. Black feathers on throat few and scattered, 

 exhibiting a raw-looking red patch. This appears to be the 

 work of the inflamed and expanded state of the numerous small 

 arteries under the skin, and not due to pigment-colouring ; and 

 the feathers on that account lose their hold and fall away, as it 

 is not of equal extent in all the individuals. This inflamed state of 

 the throat has probably some connexion with the excited nature 

 of the bird at the spring or breeding-season ; and it is not un- 

 likely that in winter the redness does not exist and the feathers 

 do not fall ofi". Before the eyes, chin, and cheeks, under-neck 

 and fringing the black line to over the eye, belly, and sides

 and under parts smoke-grey, tinged with olive^ streaked centrally 

 on the flanks and lower breast, and margined on the vent and

 olive, with several roundish bars on each feather of black, spotted 

 and mottled as well with the same on the wing-coverts and
