DESCRIPTION.* 



COLOR. (Male.) The general color above, except over the 

 shoulders, is nearly black, varying in different individuals of 

 equal age from nearly pure black to rufo-grayish black. Over 

 the shoulders the color is quite gray. The sides of the nose and 

 the lips are brownish, as is a considerable space behind the angle 

 of the mouth, and a small spot behind the ear. The neck in front 

 is more or less gray. The breast and the axillae are brownish- 

 orange. The limbs are reddish-brown, especially near their 

 junction with the body, as is also the abdomen. The hairs in- 

 dividually vary considerably in color, some being entirely black 

 nearly to their base, and others entirely light yellowish-brown; 

 others are dark in the middle and lighter at each end. The naked 

 skin of the hind limbs, the nose, and the anal region is black. 



(Female.) The general color of the female is much lighter than 

 that of the male. Above it is nearly uniformly gray, varying to 

 darker or lighter in different individuals and with age. The 

 color about the mouth is brownish, varying to rufous, of which 

 color are the axillae, the breast, and the abdomen. The sides 

 are brownish-gray. At the base all the hairs are usually brown- 

 ish, like the under-fur, with a broad subterminal bar of black, 

 and tipped for a greater or less distance with gray. The vari- 

 ation in different individuals in the general color results from 

 the varying extent of the gray at the ends of the hairs. 



* The technical matter here following includes that previously given in my 

 former paper on the Otariidce, with here and there slight verbal changes, and 

 the addition at a few points of considerable new matter, especially in the 

 tables of measurements, which are based almost wholly on an examination 

 of new material. The remarks on individual variation might be amplified 

 by reference to many other specimens, but this has not been thought nec- 

 essary.
