NOTE. 
Since the above paper was in print I have received two important publica¬ 
tions bearing upon the topic of animal parasites in foxes. 
The long awaited part of the Index Catalogue of Medical and Veterinary 
Zoology which deals with round worms is now available as Bulletin No. 114 of 
the Hygienic Laboratory of the U.S. Public Health Service. This will prove an 
invaluable aid to students of the Nematoda. 
A paper by M. C. Hall, 1920, on “ Intestinal Parasites found in Eighteen 
Alaskan Foxes” ( North American Veterinarian , i. 123-124) reports on the 
examination of eighteen foxes from Saint George Island, Alaska. “Of the 
eighteen foxes, eight were infested with ascarids, ten with Mesocestoides, and 
one with Taenia , and one fox had a number of dipterous larvae, probably from 
fly-blown flesh. Some of the ascarids have been examined and found to be 
Toxascaris, possibly T. limbata, and all of them may belong to the same species. 
The infestations were not heavy, the largest number being twelve.” 
A surprising feature of the findings is the absence of hookworms. “This 
suggests that the island is free from this worm which is a serious pest to foxes 
elsewhere.”
