canines and the inferior incisors and incisor-like canines, of the Musk-deer 

 (Moschus moschiferus}. Hunterian. 



Subgenus Tragulus. 



3494. The skeleton of the Meminna Chevrotain (Moschus Meminna). 



The vertebral formula is : 7 cervical, 13 dorsal, 6 lumbar, 5 sacral, and 13 caudal. The 

 inferior tubercle (hypapophysis) upon the atlas and the inferior ridges upon the four succeed- 

 ing cervicals are less developed than in the Moschus moschiferus : they have disappeared on 

 the last two cervicals. The pleurapophysial parts of the transverse processes are less extended 

 longitudinally in the third, fourth and fifth cervicals, but they slightly overlap each other : 

 those of the sixth cervical are disproportionately larger and deeper : the diapophysial portion 

 extends out as a distinct process : the pleurapophysial part of the transverse process is wanting 

 in the seventh vertebra : the spines of the last five cervicals are longer and more slender than 

 in the Musk-deer, and progressively increase in length, so that the last nearly equals that of 

 the first dorsal : the spine of the tenth dorsal is that towards which those of the other trunk 

 vertebrae converge, and there is a similar centre of motion indicated by the vertical spine of 

 the third cervical : the metapophysial tubercle appears above the diapophyses of the anterior 

 dorsals, projects as a distinct process midway between the diapophysis and prozygapophysis 

 of the seventh to the tenth dorsals inclusive, and gets upon the prozygapophysis in the suc- 

 ceeding dorsal and anterior lumbar vertebrae, subsiding in the penultimate lumbar. The 

 tubercle has disappeared on the tenth rib and does not reappear on those that follow, but the 

 diapophysis continues on the last four dorsals, increasing in length upon the last two, and 

 plainly showing the nature of the longer diapophyses in the lumbar region. The sternum 

 consists of seven bones. The condition of the bones of the extremities closely resembles that 

 in the Musk-deer, but there is a longer rudiment of the proximal end of the fibula, and the 

 slender metatarsals of the two outer toes or spurious hoofs, which are preserved in the left 

 hind foot in this skeleton, reach the tarsus.

3495. The skeleton of a male Napu Chevrotain (Moschus Napu). 



The length of the canines gives the sexual character. The vertebral formula is the same 

 as in the female. Eight pairs of ribs directly join the sternum, which consists of seven bones 

 and an ensiform cartilage. The slender proximal rudiment of the fibula extends more than 

 half-way down the tibia. The two large middle metacarpals have more completely coalesced 

 than in the female.

3496. The skeleton of a female Napu Chevrotain (Moschus Napu). 



The vertebral formula is : 7 cervical, 13 dorsal, 6 lumbar, 4 sacral, and 13 caudal. The 

 same characters of the skeleton as are noticed in the Meminna are repeated in the present 

 skeleton, but the slender metacarpals and metatarsals of the spurious toes in each foot being 

 preserved, show that they all are coextensive with those of the larger and middle pairs of digits :
