FURNARIUS CUNICULARIUS. G. R. Gray. (Male.) 

 Tongue, trachea, and CESophagus, as in Uppucertkia. Proventriculus longer, and slightly contracted 

 at its entrance into the gizzard, which is large, flattened, and muscular, more rounded than in 

 Opetiorhi/nchus, lined with a rugose hardened coat, and filled with small seeds, and the remains 

 of insects ; intestines of small diameter, and furnished with two rudimentary casca.

Sternum of nearly equal breadth, both posteriorly and anteriorly, but much narrowed in the

 posterior margin furnished with two deep fissures, slightly narrowed at their exit ; keel deep, 

 slightly rounded on its inferior edge, and much scolloped out anteriorly; pelvis broad and short, 

 the OS pubis projecting far backwards; the ischium terminating posteriorly in an acute process. 



Os furcatum thin, much arched, furnished with a flattened reflexed process at its junction with the 

 sternum ; the points of the rami bent forwards at their junction with the coracoids. 



Coracoids of moderate size and length, inserted deeply into the sternum ; scapula of moderate size, 

 broader near the extremity.

UPPUCERTHIA DUMETORIA. Geoff. ^- B' Orb. (Female.) 

 Tongue short, compared with the length of the bill, pointed, armed with a few spines at the base ; 

 trachea of moderate size, acted upon by one pair of sterno-tracheal muscles, which go off' to 

 the sternum, about ^ of an inch above the inferior larynx ; from the upper ring of the bronchia 

 on each side, a process proceeds upwards to the point from which the muscles diverge, to 

 which point only the rings of the trachea are continued, two spaces therefore, one on the 

 anterior, the other on the posterior side of the trachea, immediately above the bronchiee, are 

 left devoid of osseous matter, being bounded laterally by the process above mentioned, inferiorly 

 by the upper rings of the bronchioe, and superiorly by the lower ring of the trachea, which is 

 slightly enlarged ; oesophagus small, slightly dilated a little above the proventriculus, which 

 is of moderate size, and not contracted before entering the gizzard ; gizzard large, oval, very 

 muscular, inner coat hardened, deeply furrowed longitudinally, and filled with the remains of 

 insects; intestinal canal of moderate size, without cffica; rectum very slightly enlarged ; 

 liver bilobed.
