Stiles and Hassall (18946?) record this parasite from Lynx cana- 

 densis and note the presence of the specimens in the Army Medical 

 Museum, but they give no further data as to where it was collected 

 or by whom determined, probably because there 

 was no record of these facts. It would require a 

 very careful examination before anyone would be 

 safe in saying that a tapeworm collected from 

 Lynx canadensis on the American continent was 

 identical with the imperfectly known Taenia lati- 

 collis from the European lynx, and the presence of 

 this tapeworm in North America must be regarded 

 as questionable.
