TINOCHORUS RUMICIVORUS. Eschsch. (Male.) 
Trachea of uniform diameter, furnished with one pair of sterno-tracheal muscles, from which a few 
fibres descend on each side to the upper rings of the bronchiee; oesophagus of large diameter 
to about half its length, where it is furnished with a craw, and afterwards contracted to the 
proventriculus ; the craw where it is connected with the oesophagus is much contracted, after- 
wards it expands into a large sac ; proventriculus small ; gizzard large, and very muscular ; 
the grinding surfaces hard, concave in the middle, and furnished with longitudinal grooves 
in the concave part ; the intestinal canal is of moderate length, small next the gizzard, largest 
at the entrance of the caeca, from whence it slightly tapers to the cloaca, which is small ; caeca 
long, of greatest diameter at the opposite extremity to their entrance into the rectum ; the 
gizzard and oesophagus were filled with reeds, mixed with very small pebbles ; liver bilobed.

A second specimen, a female, did not differ, except in sex. Skeleton light; bones in general thin. 
Sternum broadest posteriorly, and indented on its posterior margin with two large fissures; keel 
deep, its inferior edge rounded, much scolloped out anteriorly ; a moderate-size bifid manubrial 
process between the junction of the coracoids. 
Pelvis broad, of moderate length, similar to that found among the genus Strepsilas. 
Os furcatum much arched, furnished with a small flattened process, where the ligament unites it to 
the sternum ; coracoid of moderate length, strong, furnished with a large process externally 
near their junction with the sternum ; ribs flattened, posterior process long, slightly curved, 
and narrow.

Remarks. The bill of this curious bird much resembles that of the genus Glareola, but the 
soft skin covering the nostrils is more developed, in which respect it resembles the quails, and other 
gallinaceous birds. The structure of the tarsi, feet, and nails approach near to that of Strepsilas , 
but differ in the latter being sharper, and in the scales on the feet and tarsi being more apparent, 
which may, perhaps, have been caused to a certain degree by the bird having been for a long 
while in spirits.
