depressed toward the end, where it is narrower, but rounded. 

 The upper mandible has a protuberance above, with a convex 

 and descending outline ; the sides at the base are erect, bulg- 

 ing, of great breadth, bare, and extending far back toward 

 the eye ; the unguis very large, obovato-triangular, convex, 

 decurved and rounded, the edges thin, soft, marginate, some- 

 what rearcuate ; the lower mandible with the intercrural 

 space, long, rather narrow, and bare, the lower outline of the 

 crura slightly convex, the unguis very large. 



The mouth is of moderate width ; the anterior palate con- 

 cave, with a soft median ridge, on Avhicli are about ten short 

 conical papilla}, and on each side about thirty-five slender 

 lamellae, of which the ends are not protruded. The tongue 

 is an inch and three-fourths in length, thick, fleshy, with 

 numerous conical papillae at the base, a deep median gi-oove, 

 two lateral series of bristles, and a terminal, thin, rounded 

 lobe. The oesophagus is eight inches and a half in length, 

 from an inch to three-twelfths more in width ; the proventri- 

 cular belt of cylindrical glandules an inch and a half in 

 breadth. The stomach is large, roundish, an inch and ten- 

 twelfths in length and breadth, with very strong lateral mus- 

 cles, and dense rugous epithelium forming two roundish grind- 

 ing plates. The intestine is sixty-seven inches long, and half 

 an inch wide; the coeca about four inches in length, and 

 two-tweKths and a half in width ; their distance from the 

 extremity seven inches and a half. 



The trachea of the male, seven inches and a half in 

 length, presents at the upper part a large bony expansion, 

 seven-twelfths of an inch in length, and eight-twelfths in 

 breadth. Beyond this part its width is five-twelfths, gradually 

 diminishes to three-twelfths about the middle, then enlarges 

 to five-twelfths ; after which it presents a second enlarge- 

 ment, nine-twelfths in length, an inch and two-twelfths in 

 breadth, convex anteriorly, slightly concave behind. The 

 trachea then contracts to four-twelfths, and presently ex- 

 pands to form the lower larynx, which is large and osseous, 

 but symmetrical. The bronchi arc large, of twenty-five carti- 

 laginous half-rings. The rings of the trachea are firm and 

 osseous, nine at the upper part, then the first bony expan-
