^ From the description of this worm, and its position in nodules of connective tissue in the musculature 

 of the vagina of its host, there can be little doubt that it belongs to the genus Crassicauda. The description, 

 however, which was based on fragmentary material, is not sufficient to determine whether the species is 

 identical with any of those already known. Since the male appears to be without spicules, it seems probable 

 that it is distinct at least from C. crassicauda. 



^ A larval form found in various fishes, according to Meyer (193 1) possibly the larva of B. capitatum.
