In view of the establishment of a Marine Biological Station in the Maritime 

 Provinces within the last three years, it is thought desirable to publish 

 a ' Catalogue of the Marine Invertebrata of Eastern Canada.' The object 

 of this Catalogue is to give a succinct idea of the present state of our 

 knowledge of these invertebrata, so far as the identification of species, their 

 geographical distribution, and bathymetricaljrange in the northern portion 

 of the western side of the Atlantic are concerned. 



It is hoped that this publication will act as a stimulus to renewed activity 

 in the study of marine zoology, and that it will be of use not only to zoologists, 

 but also to students of the fossils of the post-tertiary deposits of the eastern 

 portion of the Dominion.
