 Arctocephalus Gilliespii, Gray, P. Z. S. 1859, 107. t. 69, & p. 360. 



Inhab. California. 



A cast of the original skull described by Dr. Macbain, now in the 

 Museum of the College of Surgeons, Edinburgh, was sent to the 

 British Museum, from which the figure in P. Z. S. 1859, pi. 70, was 

 taken. 



The species is at once known by the length of the face : in all the 

 skulls we have of the genus, a line drawn across the palate at the 

 front edge of the zygomatic arch leaves one-third of the palate behind 

 the line, and two-thirds in front of it ; while in this species it leaves 

 only one-fourth behind, and very nearly three-fourths in front of 

 the line. 



The skull has only four grinders on each side in the upper jaw, 

 but one has evidently fallen out in front of the series and one be- 

 hind ; and the fifth grinder of the complete series, which is usually 

 in a line with the front edge of the zygomatic opening, is in this 

 species rather in front of it. 



The following are the measurements of the different skuUs in 

 inches and eighths : —
