process of the zygomatic arch instead of far behind it, as it is in 

 Eumetopias. 



Dr. Murie, most curiously, considers the skull described by Dr. 

 Peters to be the same as I have described as O. Hookeri (P. Z. S. 

 1869, p. 108). 



Dr. Burmeister considered it O. falklandica of Shaw ; and Mr. 

 Allen (Bull. Mus. Comp. Zool. vol. ii. p. 13) agrees in this opinion ; 

 but further on (p. 15) he observes that both Dr. Gray and Dr. Murie 

 have " evidently overlooked the fact that Dr. Peters expressly states 

 that 0. Philippii has a thick under-fur, whereas both the 0. Stelleri 

 and the 0. Hookeri are true hair Seals." But, in fact, this statement 

 is a mistake as regards me ; I never said that 0. Philippii was the 

 same as 0. Stelleri, but only that its skull was most nearly allied to 

 it, which I still maintain.
