1 specimen. 



From among algw :

2 specimens. (Types of S. I. Smith.) 



This species has so far proved to be the most abundant one of the 

 genus on tbe soutbern coast of New England, although the Argulus 

 megalopn is more widely distributed as regards the different species of 

 tisb on which it has l)een found. Its common host is the eel. Mr. V. 

 N. Edwards, of Wood's Holl, who has often observe<i it, state's that 

 specimens of tbis fisb are frequently infested by it to an extraordinary 

 extent, and be estimates that as many as a hundred ])arasites are oc- 

 casionally found on a single individual. The original specimens de- 

 scribed by Professor Smith were found among algae from the shore and 

 at tbe surface. The largest of bis specimens is somewhat below the 

 average sixe of tbose obtained from eels, but otherwise they are charac- 

 teristic. This species is readily distinguished from the other descrilwd 

 New England species by its black markings, which generally cover tbe 

 greater part of the body.
