process between the coracoids is rather longer; the interocular portion of the cranium is also rather 

 broader than in the above-mentioned genus ; the pelvis, coracoids, and scapula agree both in 

 shape and size with Troglodytes.

PHYTOTOMA RARA. Molina. 

 This bird being injured about the sexual organs, I could not ascertain the sex. Tongue pointed, 

 armed at the base on each side with a flattened tricuspid spine ; trachea small, of uniform 

 diameter throughout its whole length, acted upon by one pair of sterno-tracheal muscles ; 

 oesophagus funnel-shaped at the upper extremity, when distended capable of containing a 

 common pencil, at its junction with the proventriculus much smaller ; proventriculus scarcely 

 perceptible ; gizzard small, consisting of little more than a thick skin, inner coat hardened ; 

 the entrance of the oesophagus, and the exit of the intestine placed very near together at the 

 upper extremity of it ; intestinal canal very short, and of large diameter, entirely devoid of 

 caeca ; the whole length with the gizzard and oesophagus distended with a stringy substance, 

 resembling coarse spun cotton cut into short lengths.

Sternum of nearly equal breadth, both posteriorly and anteriorly, much narrowed near the middle ; 

 posterior margin nearly straight, indented with two large fissures, narrowed at their exit ; 

 between the junctions of the coracoids furnished with a bifid process; the portion of the 

 sternum to which the ribs are attached, continued anteriorly beyond the junction of the 

 coracoids ; keel of moderate size ; coracoids long, not very strong ; os furcatum long, 

 slightly arched, furnished with a flattened process, turned inwards at the point it approaches 

 the sternum. 



Pelvis broad, and short, narrowest anteriorly, the os pubis and ischium continued far backwards, 

 beyond the junction of the caudal vertebras ; ribs strong, and flattened ; posterior process 

 large ; scapula long, broadest near the extremity ; legs of moderate strength, the internal 

 processes of the tibia large, and flattened; bones of the cranium strong.
