226 ME. "W. A. FOEBES ON THE EXTERNAL CHAEACTEES 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 ]\Ir. 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 juhata} . 



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 :— inches. 



Greatest length, from nose to end of hind limbs 92-0 



Length from nose to tip of tail 81'5 



From nose to prominence in shoulder-joint 23-5 



Length of head, to end of the sagittal crest 10-5 



Length of tail, from naked skin at base 4-4 



Tip „ from anus 5'4 



Length of pectoral limb, from shoulder-joint 30-0 



Breadth „ „ at axilla 6-25 



Length of pelvic limb, from the anterior extremity of ilium .... 27-0 



Breadth of pelvic limb, at base 3-5 



Greatest breadth of pelvic limb, when the fin is expanded 7-6 



Distance between anus and preputial orifice 8'5 



Length of ear 1"75 



„ eye 1"15 



Distance between eye and ear 3'25 



„ „ nose and eye 4'75 



„ from chin to angle of mouth 3*85 



Depth of muffle 1-25 



Breadth of ditto 1-25
