NOTES ON THE BOTTOM ENVIRONMENT OF THE 



MARINE INVERTEBRATES OF WESTERN 



NOVA SCOTIA. 1 



By E M. Kindle. 



During the summer of 1914, a study of the relationship of the 

 bottom materials to the composition of the faunas living upon them in 

 the shallow coastal waters of western Nova Scotia was undertaken by 

 the writer assisted by Mr. E. J. Whittaker. At the time the report a 

 on this work was written only the pelecypods and gasteropods collected 

 during the progress of this work had been determined. The remainder 

 of the fauna which was referred to Dr. Paul Bartsch of the U.S. Nat. 

 Mus. for identification has since been studied by Dr. Bartsch and other 

 specialists. The resulting list of species includes at least one species, 

 Libinia emarginata Leach, not previously known in Nova Scotian 

 waters. The following list which I am able to prepare through the 

 courtesy of Dr. Bartsch is offered as a minor contribution to our 

 knowledge of the bathymetric range and the bottom environment of 

 the several species which were collected. For the sake of completeness 

 the present list is made to include the pelecypoda and gasteropoda 

 which were listed in the writer's earlier paper. b 



The character of the bottom at each collection station is indicated 

 in the following list of stations. 



Collecting Stations. 



Sta. No. 1. Digby, N.S., Intertidal zone, boulder strewn beach. 



2. Digby, N.S., 300 to 400 yards east of Government pier 



in 2 fathoms. Soft black mud bottom. 



3. Digby, N.S., 3 to 4 miles N.E. of Digby, Outer margin 



and inside of bar running S.W. from Bear Island; in 

 3 to 6 fathoms. Collection nearly all from muddy sand.
