The torsion Is the result of the mode of fixation, the habits of the host, and 

 the mechanical action of the external medium. It plays an important rOIe In 

 systematlzation as it enables us to distinguish the Chondracantbidae from the 

 Lernaeidae, and to transfer tlic ^enus Hjihyrion from the former to the latter.

 show the flexion and torsion characteristic of the Lernaeidae, but the ap- 

 pendages and mouth-parts are like those of Caligua.
