Only one species of this genus is known to me. It dif-

 the dorsal line sloping, the ridge broad at the base, the un- 

 guis large, roundish, convex, decurved, the laminae project-

 the intercrural space long and narrow, the outer laminae pro-

 fleshy, thick, medially grooved, papillate at the base, late- 

 rally ciliated, with the tip thin and rounded. (Esophagus 

 rather wide ; stomach roundish, very muscular, with rugous 

 epithelium, having the grinding surfaces roundish ; intes- 

 tine of moderate length and width ; coeca rather long ; rec- 

 tum very short. Trachea gradually narrowed, at the lower 

 part expanded, having six rings extremely narrow before, 

 with a transversely oblong tympanum, membranous in front. 

 Nostrils large, oblong, subbasal. Eyes rather small. Legs 

 very short, placed far behind ; tarsus compressed, with an- 

 terior small scutella ; hind toe very small, with a lobiform 

 membrane ; outer toes equal, and about double the length 

 of the tarsus ; membranes full ; claws small, slender, little 

 arched. Plumage firm, blended ; the feathers oblong and
