226 MR. W. A. FORBES ON THE EXTERNAL CHARACTERS AND 
Since the subject of the present paper passed through my hands Mr. Allen’s elaborate 
‘History of North-American Pinnipeds’ (Washington, 1880) has been published, and 
our knowledge of Otaria gillespii much increased thereby, Mr. Allen having been able 
to examine many skins and skeletons of the species, as well as to give full details of its 
habits in a state of nature. A good figure, however, of this species still remains a 
desideratum. The drawings accompanying this paper having been made from the fresh 
animal by Mr. Smit (under my own supervision), their publication will, by filling up this 
blank, tend to still further complete our knowledge of this animal. The detailed 
measurements and description of the adult male examined will also still further 
supplement Mr. Allen’s account, whilst the notes on the anatomy of the soft parts, 
hitherto unknown in this species, will perhaps also be acceptable, as confirming, or 
adding to, our knowledge of these parts as described in Dr. Murie’s elaborate and 
exhaustive treatise on Otaria jubata’. 
The animal examined by me was a male, perhaps adult, but by no means aged, as 
may be seen from the condition of its teeth and skull, now preserved in the College of 
Surgeons. The Brighton animal, already alluded to, was probably somewhat older, as I 
am informed by Prof. Flower. 
The following measurements were taken, by means of calipers, on the unskinned 
animal :— ened
