that was removed. The nostrils were middle sized, ap- 

 proaching each other, and placed on the upper part of the 

 muzzle ; the head was thick and clumsy, swelling in the 

 upper part and rather flatted above the eyes ; it terminated 

 in a gross projecting muzzle; the upper lip was entirely 

 divided into two distinct portions, furnished at their ex- 

 ternal edge with thick short and bristling hairs ; the under 

 lip was furnished in the same way ; the neck was extremely 

 short, but yet distinct. The anterior members are placed 

 almost under the head, and nothing is seen externally but 

 a short compressed fore-arm, terminated by a fin-shaped 

 hand, having four fingers enveloped in the skin, of which 

 the middle and the two lateral alone are terminated by 

 a short nail ; the body was thick and short ; the tail thick 

 at the origin, and flat and broad towards the end; the 

 skin was brown, thick, much wrinkled, and furnished with 

 a few hairs of a gray colour.

 and thick skin of an ashy lilac. The Negroes call it Cercon. 



This Lamantin has the osseous head shorter and wider 

 altogether than the American species. The lower jaw is 

 also much less rounded, and the upper as well as the rest

But one species as Cuvier observes is known. It in- 

 habits the Indian seas. Its head is rounded towards the 

 top, oblique from the forehead to the muzzle, which last is 

 vertical and terminates abruptly. This part of the face 

 is formed by the upper lip which hangs from each side of
