this more clearly, I subjoin fif^ures (fig. 6) of the palates of two 

 skulls of Otaria ursina, wliich I observed in the Eoyal Museum at 

 Berlin, in August 1875. In the skull marked A the opening of 

 the palate is normal, in that marked B it is abnormally elongated ; 

 but in all other respects the two skulls are perfectly similar. 



The skull (figs. 3-5) which I take to be that of a female has 

 been already sufficiently described. It is 9 inches long by 'l| inches

 and again in the view of the uuder surface of the skull (fig. 4).

 by 5 inches broad. It does not appear necessary to figure it, as it 

 reproduces the characters already remarked in the female on a 

 slightly larger scale.

 skin of the type specimen is preserved in the Zoological Gallery of 

 the Museum at the Jardin des Plantes. It is marked " Otarie cendree
