The vertebral formula is : 7 cervical, 12 dorsal, 7 lumbar, 2 sacral, and 25 caudal : a few of 

 this series, and the atlas, are wanting. The cervical transverse processes incline downwards : 

 their pleurapophysial divisions from the second to the sixth increase ; but this part is want- 

 ing in the seventh, and the transverse process is imperforate. The accessory tubercle is well 

 developed on the diapophysis of the ninth and tenth dorsals ; the diapophysial part disap- 

 pears on the eleventh and twelfth dorsals, in which the accessory tubercle becomes divided 

 into two well-marked processes, viz. the met- and an-apophyses. The diapophysis reappears 

 on the first lumbar, and progressively increases to the antepenultimate one. The metapo- 

 physis exists as an elongated tubercle outside the prozygapophysis from the eleventh dorsal 

 to the last lumbar, and the anapophysis is present from the tenth dorsal to the sixth lumbar. 

 The haemal arch is present in a few of the anterior caudal vertebrae. Seven pairs of ribs 

 directly articulate with the sternum, which consists of six bones. The humerus is imperfo- 

 rate at its distal end. The specimen is from an immature animal still retaining the deciduous 



molars and canines. 



Mus. South. 



5005. The skull of an adult male Semnopithecus Entellus.

 The temporal ridges do not meet to form a parietal crest. The premaxillaries ascend above 



the lower half of the nasals.
