APPENDIX TO THE REPORT ON THE SEALS. 



The Myology of the Pinnipedia. By Wm. C. Strettell Miller, M.D. Edin. 



INTRODUCTION. 



This memoir embodies the result of a series of dissections of Seals, commenced in 

 November 1886, in the anatomical department of the University of Edinburgh, at the 

 request of Professor Sir William Turner, to whom I am much indebted for his kindness 

 in placing the material for this research at my disposal. 



The animals which I have dissected are as follows : — an adult Phoca vitulina, a half- 

 grown imperfect specimen of Phoca hispida, an imperfect specimen of a pup of Phoca 

 barbata, two partially damaged young specimens of Arctocephalus gazella brought by the 

 Challenger from Kerguelen Island, and a specimen of Macrorhinus. leoninus, also brought 

 by the Challenger from the same island, which, unfortunately, was so imperfectly pre- 

 served that the hind limbs were the only parts which could be dissected. In addition, 

 a half-grown specimen of Phoca vitulina was kindly given to me by Professor Cossar 

 Ewart for this investigation. 



The plan which has been pursued in drawing up this description has been to take 

 the arrangement found in Phoca vitulina as the standard, and to describe fully the muscles 

 as seen in that animal, and then to point out wherein the other Seals agreed with 

 or differed from it ; but as Arctocephalus is far removed from Phoca vitulina in its 

 structure, its myology has had to be described in considerable detail. It must be 

 understood that when I use the term Phocinse in the course of my narrative I mean by 

 it Phoca vitulina, Phoca barbata, and Phoca hispida. Opportunity has frequently been 

 taken to compare the result of my own dissections with those of previous writers. 



The muscles have been arranged in natural groups, and so far as possible the nervous 

 supply of each muscle has been stated. 



The memoirs on the myology of the Pinnipedia which I have consulted in connection 

 with my dissections are as follows : —
