ter in his very recent work of 1844, " It is remarkable that the number 

 of the cervical vertebrae should be the same in all Mammals, the long 

 necked Giraife and the seemingly neckless whale having each 7 vertebrae, 

 like all the rest." 



I cannot lay my hands upon any osteological formula for Sus, and I 

 am aware that the tame breeds of the Pig manifest a strange variability 

 in regard to some parts of their osseous frame-work. But I believe 

 such deviations do not belong to the vertebrae of the neck in Sus, and 

 upon the whole I think that the citations and quotation I have given 

 will fully justify my having called special notice to the 5 vertebrae in 

 the neck of Porcula, a perfectly and exclusively wild type. 



I now proceed to the Stilthorns or Muntjacs. 



Stylocerus Ratwa. Soft anatomy and cuticular organs. Young 

 male, procured in April, died in October. Two-thirds grown yet not 

 the least sign of horns. Small knobs as in the female in lieu of horns. 

 Eye-pits large. Mufle large. Facial creases conspicuous, and their 

 glands developed. Feet-pits in the hind extremities only, but there 

 conspicuous. Inguinal pits none. No calcic gland nor tuft. Canines 

 distinct but not yet exserted from the lips. Mamma 4. Liver with 

 one grand lobe very partially divided, and a second small lobe. Gall- 

 bladder none. Lungs with a primary dichotomous division. Right 

 lobe quadripartite ; left, tripartite and a lobulus. Spleen round, flat, 

 attached to outer side of paunch. Pancreas tongue-shaped, narrow, 

 pale ; its ducts vague and doubtful. 4 stomachs a l'ordinaire. Great 

 gut 10. 10. 0. Firstfoot, or that next the ccecum, as wide nearly as it, 

 or 2 inches. Ccecum 13 inches by 2|-, void of sacculation and banding. 

 Small gut 41. 0. 0. very narrow, the average width being half an inch. 



Osteology (from a mature specimen). The vertebrae of the spinal 

 column are as follows : Cervical 7. Dorsal 13. Lumbar 7. Sacral 5. 

 Caudal 13 — 14. Total 45-6. The sternum consists of 7 bones, which 

 are broad and flat, except the first and last, and these are narrow and 

 cylindric. Ribs 13, whereof 8 are true and 5 false. The ribs are 

 compressed, or very little bulged laterally, and the chest exhibits the 

 perfection of the " thorax carinatus" type, whence one is rather 

 surprised at the breadth and flatness of the sternal plates ; the very 

 reverse moreover (to add to the riddle) being equally true of the broad- 

 chested climbing Wah ! Ensiform cartilage of the sternum large and
