decided central line of chestnut following the direction of the shaft and becoming spatulate 
at the tip ; the web of each feather is transversely barred and blotched with black; the 
chest and abdomen are sandy chestnut, becoming more intense on the under tail-coverts ;

Ortyx ocellatus, Gould in Proc. of Zool. Soc., Part IV. p. 75. 
Two examples of this bird are all that have come under my notice; of these, the one from which my 
description was taken is in the Museum of the Zoological Society of London, and the other, an exceedingly 
fine specimen, in that of the Jardin des Plantes. It is very nearly allied to the Cyrt onyx Massena, hut 
differs from that species in having the black marks on the face larger and more conspicuous, in the 
brighter chestnut of the lower part of the abdomen, and in the stripes down the centres of the feathers 
of the upper surface being chestnut instead of buff; it differs also in the greater development of the 
secondaries and tertiaries, which are so much lengthened, that when the wing is closed the tail is scarcely 
distinguishable. 
I regret to say that nothing whatever is known of its history. 
Habitat. Guatemala. 
The figures are of the natural size.
