Fill: 811- WATER CRUSTACEA FROM LABRADOR AND 

 NEWFOUNDLAND.

It is a well-established fact that the fauna of the eastern coast of 

 boreal North America is very closely related to that of northern 

 Europe in many ways. An additional evidence of this will be given 

 here from the relationships of the minute fresh-water Crustacea. 

 Of the seven species of Cladocera, for instance, all are found in 

 northern Europe. Certain of these are Arctic species, and in Europe 

 are found only at higher latitudes, but that is simply an additional 

 proof of the boreal character of our Labrador coast. As an example 

 of this, Eurycerciis glaciaUs is found only in the extreme northern 

 border of Europe, very much farther north than the localities from 

 which the present material came. Macrofhrix hirsuticornls is re- 

 corded here for the first time from the Western Hemisphere. A 

 single species of Ostracoda was obtained, but that in considerable 

 numbers. It seems not to have been previously described, but is 

 related to certain European species. The single species of Copepoda 

 is also a species common to Europe and America. 



The material on which the present paper is based has been pre- 

 sented to the U. S. National Museum. It was in six separate lots, 

 five collected on the eastern coast of Labrador at about latitude 52° 

 north, b}^ Dr. Glover M. Allen. The other material was from Funk 

 Island, a small island a considerable distance off the coast of New- 

 foundland and in about latitude 49° north. It was collected by Mr. 

 Owen Brj^ant. 



The data for these collections are as follows: 

 1. From St. Marys River, running into Lewis Inlet, Labrador, 

 July 12, 190G. "Among grass with scum and Sphagnum." 



2. From fresh-water pools on island. Battle Harbor, Labrador. 

 July 14, 1906. 



3. From two fresh-water pools on island, Battle Harbor, Labrador. 

 July 14, 1906.
