dense, and forming two flat grinding plates. The intestine is 

 four feet three inches long, from three-twelfths and a half to 

 two-twelfths and three-fourths in width ; the coeca nine- 

 twelfths long, and two-twelfths in width. The rectum is 

 three inches long, five-twelfths wide at first, but dilating into 

 a globular sac, an inch in width. 



The trachea, six inches and a quarter in length, is much 

 flattened, at first three-twelfths and a half in breadth, then 

 contracting gradually to two-and-a-half-twelfths, but at the 

 lower part of the neck enlarging to four-and-a-half twelfths, 

 then assuming a trigonal form, with an anterior acute carina. 

 The rings, an hundred and two in number, are broad and 

 osseous, in the lower carinated part slender and widely sepa- 

 rated ; but besides these, eight are united to form part of the 

 expansion on the lower larynx, which is of an irregular form, 

 projecting anteriorly Avith a rounded bulge, and dilated on the 

 left side, its greatest breadth nine-twelfths of an inch. The 

 bronchi are of moderate length, with about thirty half- 

 rings. 



The nostrils are narrow, oblong, three-twelfths long, sub- 

 medial near the margin ; the eyes small. The legs are very 

 short, and placed far behind ; the tibia bare for a quarter of 

 an inch ; the tarsus extremely short, much compressed, with 

 about sixteen medial and six outer small scutella, the rest 

 reticulated with small angular scales. The hind toe very 

 small, slender, with a lobiform membrane, and twelve scu- 

 tella ; the second with twenty-five scutella extending from 

 the base to the end ; the third with thirty-two ; the fourth 

 with forty scutella, and a little shorter than the third, which 

 is double the length of the tarsus ; the outer interdigital 

 membrane emarginate. The claws small, arcuate, com- 

 pressed, rather acute, the inner edge of the third a little 

 dilated. 



The plumage is full, soft, firm, and blended. The feathers 

 of the upper part of the head and nape are elongated, linear, 

 and erectile, forming a narrow crest ; of the rest of the head 

 and upper neck small ; of the lower parts oblong, firm, and 

 glossy ; of the sides elongated and curved ; of the shoulders 

 abrupt ; of the upper parts ovate ; the scapulars of moderate
