PARASITES OF FISHES OF THE WOODS HOLE REGION. 
409 
Alphabetical lists have been prepared, both of the parasites which have been 
found and the fishes which have been examined; in the former the name of the host 
is also given. By means of these lists and the numerous cross references, which 
will be found in the text, the arrangement of the material under the hosts should not 
be inconvenient to the zoologist; while the collection of the several species which have 
been found undereach host, together with such food notes as have been made, will be 
a beginning of the practical economic study of parasitism in the food-fishes. It is 
very desirable that a summary of the invertebrate intermediate hosts of fish parasites 
be made, but thus far very little work has been done on the parasites of invertebrates. 
Efficient assistance in the collection of material was rendered in the summer of 
1899 b} r Messrs. 4. A. Stewartson and W. W. Francis, and in 1900 by Mr. C. W. 
Stone. Grateful mention is also made of Mr. Vinal N. Edwards, whose amazing- 
energy, vast knowledge of local conditions, and unfailing accuracy have been of 
invaluable service.
