Leidy in his Synopsis of Entozoa (1856, p. 42-58) gives 

 Agamoncma capsularia (?), Diesing, as found, as well as in the 

 intestines, " coiled in sacs of peritoneum " of shad, herring, etc., 

 and having as characteristics, " Body slender, most narrowed 

 anterioi'ly, mouth small, circular, surrounded by an undivided 

 lip. Tail short, obtusely conical, minutely nuicronate, etc." — 

 •A description which closely fits the less developed of my 

 forms.

 with the cod and harldock as hosts (and, tl()iil)tfully, man); 

 the description given by Schneider of this form ("62, p. 302; 

 being " Asexual nematoid in abdominal cavity, and among the 

 muscles of several marine fishCvS,'" and having 3 indistinct labial 

 lobes, one of which supports a tooth, " the oesophagus having 

 posteriorly a caecal ])rolongalion."' This agrees with some of 

 my specimens, as regards the head at all events. 



Cobbold (1865, p. 325) furtlier records the iindiug of Filaria 

 capsularia. on liver of hemp fish, in Manchester.
