 extensively free at the sides oidy. The external nostrils aro nearly 

 lernunal and ai'o rather near to;^ether, the space between thcni beinjjj 

 e(|iial to jtist half that betwetMi the basesof the eyelids ami abontthreo- 

 lifths that between the ehoana-. The width between the eyes behind 

 is ecpnd to the axial len<,^th from the .sanu^ to the eml of the muz/.le. 

 The width of the head enters the len;;th to the jjroin seven times. The 

 lenjith from tlie muzzle to the axilla tMiters the distance from the latter 

 to the ji'roiu I v time,'.

 gate. Their lenjjths, bcfjinniuf; with the shortest, are: Fore-foot, 2, .''», 

 ;5, 1 ; hin<l foot, 1, o, 2, ;j, 4. The phalanj-vs are: Forefoot, 2, 2, ,3, 2;
