780 DR. J. MTJRIE ON MACACUS SPECIOSUS. [June 18, 



pubis to ilium ; angulation of the tail at its root ; limbs somewhat 

 shorter than in the Rhesus ; shaft of humerus bent forwards above ; 

 lower end of femur and upper end of tibia with a backward bend, 

 giving unusual prominence to the knee. 



8. Observations on the Macaques. — IV. The Japanese 

 Monkey. By Dr. James Murie, F.L.S., F.G.S., &c. 



[Received June 4, 1872.] 



" La Macaque que nous publions aujourd'hui nous presente une 

 de ces nouvelles combinaisons de caracteres qui ne nous permet de la 

 rapporter a aucune autre espece de son genre, et qui lui donne une 

 existence speciale que ne ferait, sans doubte, que confirmer son etude 

 plus particuliere et la connaisance plus detaille'e, plus exacte de sea 

 organes et de son naturel " *. These words preface F. Cuvier and 

 St.-Hilaire's description of the " Macaque a, face rouge," their Maca- 

 cus speeiosus. A good illustration accompanies the text. MM. Du- 

 vaucel and Diard are credited with having sent home the new animal. 



Temminck, in his ■ Fauna Japonica,' besides sundry remarks, in 

 correction of Cuvier as to its habitat, agrees as to its specific distinc- 

 tion, though regarding it as truly belonging to the genus Inuus. 

 A comparison with I. ecaudatus follows, the exterior and skeleton 

 being noted ; but no mention is made of its internal anatomy. Two 

 plates are devoted to portraying the old and young animals, in large 

 views of the head (fore face and profile), the buttocks, the feet, and 

 the skull in several views. 



Notwithstanding the foregoing labours, and the fact that the 

 species has not been questioned, there still remain a few points of inte- 

 rest worthy of special mention. What Cuvier said, as above quoted, 

 is but partially true ; for Geoffroy's Macacus arctoides approaches 

 closely in several respects. A fuller comparison of these two forms is 

 now, I believe, necessary, especially as Dr. Anderson's notices f of 

 the latter (his M. brunneus) reveal peculiarities partly shared by its 

 congener. Temminck's figures of the young and adult crania of the 

 Japanese species (If, speeiosus) preclude the necessity of my giving 

 illustrations ; but to his remarks and comparison with the Magot I 

 may add a commentary, besides fresh observations. 



The male investigated by me lived in the Society's menagerie a 

 few years, dying ultimately of tuberculosis. Its skeleton is preserved 

 in the British Museum. 



As respects the dentition of the skull, the hindermost molars appear 

 as if about to issue from their alveolar sockets, but are not perfectly 

 irrupted. The upper canines are smaller in size than those of the 

 Rhesus or Pig-tailed Monkey about the same age. The diastemata 

 are restricted, and the backward obliquity of the first lower premolar 

 less marked. Hence the dentition as a whole is of a more uniform
