THE FOEMS DESCRIBED AND FIGUEED IN THE FOREGOING MONOGRAPH OF PACIFIC 

 CETACEA, BY CAPTAIN C. M. SCAMMON, U. S. E. M.

The object in the following Catalogue — besides bringing together condensed 

 descriptions of the species of Cetaceans reported from the Pacific, and such of 

 unknown habitat as might have come from that ocean, with references to such 

 figm'es and fuller descriptions as may be readily consulted by the student — has 

 been especially to determine, as exactly as possible, the genera and species described 

 by the author in the preceding pages of this work, in order that his figures and 

 contributions to our knowledge of the habits and natural history of those animals 

 may have their fullest value for the scientific student of the group in question. 



I have adopted in full the general groups eliminated by Professor Theodore 

 Gill, of the Smithsonian Institution, in the Catalogue of the Families of Mammals 

 published by the Institution ; a course warranted not less by the scientific standing 

 of- the author in question, than by the paucity of works of reference on this coast, 

 and the confusion which has hitherto existed among the best naturalists in regard
