Results of the Hudson Bay Expedition, 1920 
II. The Gasterosteide. 
By Puitrp Cox, Pa.D. 
In the winter of 1920-21, I received a collection of sticklebacks from Mr. 
Frits Johansen, which he had made in James and Hudson Bay and the tributary 
waters at the instance of the Biological Board of Canada. It is of special 
interest as being the largest collection of such material ever made in those 
regions, about whose fish fauna so little is definitely known. It consists of 
nearly 200 specimens, which are in a good state of preservation. 
Our knowledge of the sticklebacks of Hudson Bay is merely fragmentary 
and very incomplete. To illustrate this, it is only necessary to state that in 
“Fishes of North and Middle America,’ Jordan and Evermann, 1896-1900, 
Hudson Bay is mentioned only once and that in a footnote. The Atlantic and 
Pacific coast forms, as well as those of the interior, are well known through the 
writings of Richardson, Reinhardt, Storer, DeKay, Girard, Eigenmann, Kendall, 
and others; but little is known of the species of Hudson Bay. Information from 
that remote and hitherto inaccessible region leaked out slowly. It is gratifying, 
however, to learn that the Biological Board of Canada is making successful 
progress in unlocking the hidden treasures of the north, and making them known 
to the scientific public. 
Sticklebacks were taken at 15 stations, which, for convenience of reference, 
I have numbered, giving also the dates.
