]2d , Canadian Ardtic Expedition, 1913-18 
FLEAS. 
A small collection of fleas, of great interest on account of the meagre char- 
acter of our knowledge of the fleas of the Canadian Arctic, was sent to Hon. 
N. Charles Rothschild, London, England, for identification and report. Un- 
fortunately, however, they have been lost, and consequently no report on this 
group has been prepared. They were collected from the following hosts: 
Continental Arctic Fox, Alopsx lagopus innuitus (Merriam). 
Parry's Ground Squirrel, Citellus parryii (Richardson). 
Keewatin Arctic Hare, Lepus arcticus canus Preble. 
C. Gordon Hewitt, 
Dominion Entomologist.
