Tlii.s species has a {jood deal of allinily in its character to the C. 

 paroticiis I>air<l, but it dilVeis in important points of structure, as well 

 as in its external appearajice. 



Its oeii(>ial proportions are not slender; and the limb.s, especially the 

 posterior ones, are very stout. The tail is Ions', i>»<l •» coinpres.sedfroin 

 the base. It does not bear a fin at any i)art. lis length, in the sinj^le 

 spetuiuen before me, is eijual to that of the head and body (in(!ludingtho 

 vent), less the distance from the eye to the end of the muzzle. The 

 head is short and the muzzle is contracted, ami is steeply rounded in 

 profile. The distance from the muzzle to the axilla enters the length 

 from thea.Killa to the groin 1\ times. The width of the head enters
