lower edge of the belt of gastric glands to its extre> 

 mity. Its inner coat is very tough. The pylorus 

 has a slightly thickened rim, below which, occupying 

 more than half the circumference of the intestine, 

 is a kind of valve projecting about one-twelfth of an 

 inch, in a recurved line, with a smaller curved line 

 within it attached to one side. These curves are ter- 

 minated by three very small knobs. The intestine is 

 convoluted in parallel transverse lines, and on account 

 of its extreme tenuity and the great number of its folds, 

 presents a very singular appearance. It is larger at its 

 upper part, where its diameter at the entrance of the 

 gall-ducts, six inches from the pylorus, is two and a 

 half twelfths. It continues so for about six inches more, 

 then gradually contracts, and for several feet has a dia- 

 meter of only one-twelfth and a half, in some parts a 

 little less, but towards the cceca, for about a foot it is 

 one-eighth in diameter. The cceca are four and a half 

 inches distant from the rectum, one placed a little low- 

 er than the other, adherent, oblong, thick, with a very 

 small cavity, and four-twelfths long. The rectum, or 

 lai'ge intestine, for two inches has a diameter of one 

 inch and five-twelfths, after which it dilates into the 

 large irregularly globular cloaca. The gall-bladder is 

 globular, one inch in diameter. 



The nostrils are oblique, lateral, oblong, covered 

 above with a thin-edged sinuate flap of the cere, and 

 having beneath a soft tumid membrane. The eyes are 

 of moderate size ; the eylids feathered, and having three 

 rows of short ciliary bristles. The two puncta lachrv- 

 malia are so large as readily to admit a middle-sized 

 pin. There is no projecting lachrymal bone, and the
