In its internal anatomy, as in many of its external characters, the Cryptoprocta feror 
approaches the Cats. The stomach is a long pouch, strongly bent upon itself at its 
posterior third, and slightly contracted at its first third, where it lies upon the trihedral 
elongated spleen. Its rounded end extends left of the esophagus about half an inch, 
the diameter of the stomach being three quarters of an inch at the cesophageal entrance; 
it then contracts to about five eighths of an inch, becomes again dilated to its previous 
dimensions, and bends upwards, gradually narrowing to the pylorus: the length of the 
first portion is two inches and a quarter, of the second, one and three quarters: fol- 
lowing the middle line of the stomach, its length is three inches and a half. Along its 
first or descending portion the stomach is furnished externally, both dorsad and ven- 
trad, with strong longitudinal muscular fibres: these scarcely extend to the curved 
part, and are not visible on the ascending portion. The length of the small intestines 
is four feet and three inches ; of the cecum, an inch and a sixth; of the large intestines, 
five inches and a half. The cecum at its base is broader than the small intestine ad- 
joining it, the two together about equalling the colon in capacity of tube: from its base 
it narrows gradually to its extremity, which is only slightly obtuse ; its direction is 
parallel to the small intestine. 
The teeth in the individual examined are of the deciduous class only, and conse- 
quently cannot furnish permanent characters. It may, however, be desirable to de- 
scribe them. They consist, in the upper jaw, of six closely set incisors, of which the 
four intermediate are small, with their crowns a little flattened and somewhat impressed 
transversely ; the outer incisors are much larger than the intermediate ones, and have 
on their external surface somewhat the appearance of canines ; they have an internal 
process, against which the crowns of the corresponding teeth of the upper jaw close. 
The canines are distant from the incisors, and project from the jaw about twice the 
length of the outer incisors; they are curved backwards. Immediately adjoining to 
the canine on each side are two small false molars ; the first nearly cylindrical, with a 
slight process on the outer and posterior part of its crown; the second having a slender 
lengthened crown, and two roots. A space, equal in length to the second molar, in- 
tervenes between it and the third, which is large and composed of three sharp, longi- 
tudinally disposed, tubercles ; the anterior having a small process behind ; the second, 
twice the length of the preceding one, is simple and directed somewhat backwards ; the 
third forms a long transverse ridge: the middle tubercle is, at its base, somewhat 
lengthened inwards, but is without process or spur in this direction. The fourth 
molar, adjoining the third, is irregularly triangular ; its outer and broadest portion is
