282 APPENDIX. 
to the classification of the Cetacea. For convenience in reference I have also, for 
the most part, adopted the minor divisions used by Dr. J. E. Gray in his Supple- 
mentary Catalogue of Seals and Whales in the British Museum, 1871; though many 
of them appear to have a more subordinate value than that ascribed to them by 
that eminent naturalist. In quoting his works, for greater brevity, I have simply 
referred to them by their dates, namely : the British Museum Catalogues of 1850 and 
1866 ; the Synopsis of Whales and Dolphins, 1868 (containing, with others, the plates 
of the Zoology of the Erebus and Terror, partially published in 1846); and the Sup- 
plementary Catalogue of 1871. 
I have to thank Captain C. M. Scammon for placing all the material and infor- 
mation in his possession at my disposal, for examination ; also, Professor S. F. 
Baird and Doctor Theodore Gill, of the Smithsonian Institution, for assistance ren- 
dered in many ways, without which I should hardly have been able to complete 
this Catalogue. 
I have also incorporated extremely brief notices of the material from which 
each species has been described, and the museum in which the specimens are pre- 
served ; "S. I." referring to the National Museum, in charge of the Smithsonian 
Institution at Washington. I have also endeavored to refer to all the remains of 
Cetacea preserved in the collections on the west coast. 
Completeness is not claimed for this list ; in fact, it can hardly hope to be 
attained for a considerable period, when the difficulties and expense connected with 
these researches are appreciated. Still, it is to be hoped that, in bringing together 
this material, something has been accomplished in rendering the path easier for 
subsequent students. 
The references to plates opposite the specific name adopted, are to the plates' 
and figures in the preceding portion of this volume.
