I. IntRopuctory REMARKS. 
ALTHOUGH upwards of a century has rolled past since our daring and intrepid 
British navigators, Dampier and Captain Cook, with the latter’s no less zealous 
naturalist and companion voyager, Mr. Foster, made known the Eared Seals (Otariidie) 
to the world, so little is yet known respecting their internal anatomy and soft parts, 
that any observations relating thereto, even if devoid of novelty, cannot fail to be of 
some interest in illustration of the structure of that remarkable group. I must not 
omit mention, though, of Steller, who long ago, in his ‘ De Bestiis Marinis,’ furnished a 
fair descriptive history and anatomical outline of the Sea-bear, Ursus marinus, and a 
short notice of the Sea-lion, Dampier’s Leo marinus, both studied by him in their native 
haunts, Behring’s Straits. His writings, however, difficult of access, render a further 
memoir not the less useful, especially as he has but passed in rapid survey many of the 
more important structures, and to others omitted all reference. 
The present Memoir more particularly treats of the external characters and the organs 
of movement. The viscera, nervous and vascular systems, &c. wili be included in 
another part, the two forming a descriptive account of the anatomy of Otaria jubata 
as a type of the group. 
Originally I had intended to compare throughout the structure of this Eared Seal 
with the Earless or Common Seals, and with the Walrus, &c.; but, led to understand 
that the simple and tolerably complete descriptive anatomy of the specimen might form 
of itself a sufficiently lengthy communication, I simply produce it in that form. 
It is greatly to be regretted that the precise age of our Sea-lion, when captured, was 
not ascertained with the accuracy which could be desired. What is known of its history 
has been to some extent already published'. I have besides derived information from
