8. On the Muscular Anatomy of Proteles as compared with 

 that of Hyoena and Viverra. By M. Watson, M.D., 

 Professor of Anatomy, the Owens College, Manchester. 



[Received June 19, 1882.] 



Having recently had an opportunity of investigating the anatomy 

 of a male specimen of Proteles cristatus which lately formed part 

 of the Society's collection, I thought it advisable, considering the 

 rarity of the animal, to make a careful dissection of the soft parts. 



The osteology of Proteles is already well-known through the 

 works of Isidore Geoffroy St.-Hilaire ' and of De Blainville'^ ; and 

 I need not further refer to it beyond stating that in my specimen, 

 as in that examined by Professor Flower^, the ribs are fifteen in 

 number on each side, and that the dorsal vertebrae are fifteen and 

 the lumbar five in number. The last rib on each side is extremely 

 short, measuring only one inch in length, and on this account had 

 probably been overlooked by St.-Hitaire and De Blainville, according 

 to both of whom the ribs and '^^saff^ve^t&brse of Proteles are four- 

 teen in number and the lumbaP,Vei_t^&«S' six. 



The visceral anatomy of Prbieles Isisi been so carefully described 

 by Professor Flower^ that I n'eed/^St d^"" more than refer to the 



I Memoires du Museum d'Histoire 15'alurelle, tome xi. 1824, p. 354.
