Mr. Allen, in his paper on the " Eared Seals of the North Pacific," 

 above quoted, figures the skulls of two old males and of a young 

 female, and of another younger, only 35 days old, and the palate o' 

 another rather older female. The three youngest skulls have the 

 internal nostrils elongate, narrow and acute in front (t. ii. figs. 8, 9, 

 10, t. iii. figs. 1, 2, 3) ; and this form is continued in two fig-ures of 

 older skuUs (t. ii. fig. 2, t. iii. fig. 4), but the aperture is represented 

 wider and vfith a rounder front edge in the oldest skull (t. ii. figs. 

 3 & 4).
