nounce a decisive judgment upon the matter if we rely upon 
the description alone. The figures which Bassi gives, how¬ 
ever, speak strongly for the view that/}, magnum and D. Amcr- 
icanum are the same species. I should hesitate somewhat to ex¬ 
press myself in favor ol their identity were it not foi the fact 
that Leuckart has written to us that he also considers the 
species identical and that Blanchard, in a recent lettei to me, 
refers to this parasite as D. magnum. Both Leuckart and 
Blanchard, as well as myself, have examined D. Amencanum , 
and although Blanchard already knew my views upon this 
subject, Leuckart did not, but came to his conclusion entirely 
independent of me. Thus, according to the views of Leuck¬ 
art, Blanchard and myself, the correct name of the parasite 
is D. magnum Bassi, while F. carnosa Hassail, F. Americana 
Hassail and D. Texanicum Francis are synonyms of D. magnum. 
Should it, however, be proven that Leuckart, Blanchard and 
1 are wrong in regard to the identity of F). Amencanum 
and D. magnum , then the name D. Americanum Hassall (Sept. 
1891), must by all means, as stated above, take piioiity over 
the name D. Texanicum Francis (Oct. 1891) since the former 
antedates the latter by one month in publication. 
To Dr. Hassall is due the credit of insisting upon a specific 
distinction between D. hepaticum and the large livei-fluke 
found in American cattle, and this is not lessened in the 
slightest, even if we accept D. magnum as the proper specific 
name of the parasites.
