1 124 On the Cat-toed Sub-plantigrades. [Nov, 



Walls and Benturongs on the other. I pretend not to account for, 

 I only report, the frugivorous habits, gentle disposition, ursine arm, 

 feline paw, profoundly cross-hinged yet grinding jaws, and purely tritu- 

 rant and almost ruminant molars, of Ailurus ; and to these I now 

 proceed to add, however they may square or not with systems which 

 Cuvier himself was forward to deprecate the premature march of, the 

 details of the soft anatomy of Ailurus, merely adding--in this place with 

 reference to the socks of Ailurus, that we have examples of this pecu- 

 liarity not only among the plantigrade Bears (Ursus Maritimus) but 

 also among the digitigrade and purely carnivorous Weasels (Lutra 

 latrix.) 



Soft anatomy. — The anus, peroneum, and prepuce, are entirely free 

 from glands and pores. There is no trace of the Cacodean anal glands 

 and pores of the Mustelidse, or of the Euodean preputial ones of the 

 Viverridse, so that in this remarkable respect Ailurus is affined to the 

 Feline or Ursine, and sundered alike from the Musteline and from the 

 Viverrine groups. Anus large, nude, void of all trace of gland or pore. 

 All the proximate parts covered with hair. Perineum simple. Scro- 

 tum wanting. Testes long, narrow, concealed in the groin. Penis 

 directed forwards, dog-like, and furnished with a small simple bone. 

 Vulva simple. Uterus bicornute with large horns. Teats eight, and 

 ventral, or rather disposed in fours, whereof the upper 4 are sub-pec- 

 toral, and the lower 4, sub-inguinal. Intestinal canal five lengths of 

 the animal, nine feet long, of great equal diameter, void of ccecum and 

 about one inch in width. Stomach large, simple, membranous, thick 

 coated and glandular towards the lower orifice, hemispheroidal, with 

 terminal orifices, of which the lower one for about 3 inches presents 

 the character of a subsidiary stomach or glandulous neck to the ordin- 

 ary stomach. Great diameter of the stomach 11 to 12 inches. Small, 

 4| to 5^ inches, exclusive of the glandulous neck. Spleen tongue- 

 shaped, purple red, 5^ inches by \\. Lungs 6 lobed. Liver 6 lobed 

 and a lobulus. Gall bladder very large, ovoid, occupying the whole 

 centre of the largest lobe of the liver and passing through from side to 

 side of it. Tongue smooth, simple, not unusually extensile. Pupil of 

 the eye round ordinarily, and but slightly. Third eyelid capable of 

 being brought over the whole organ nearly. 



The above details of the soft anatomy, like those of the hard, offer
