372 THE RELATIONS OF CYCLOPTEROIDEA GILL. 



character of the pectorals autl in the position of the ventrals in a 

 natural family than is manifested in the present. Therefore, I formerly 

 suggested the isolation of the two then known into distinct subfamilies. 

 A subsequently discovered type — Paraliparis — was later recognized by 

 Jordan and Gilbert as the representative of another [Amitrince) distin- 

 guished by the want of the ventral sucker. In the so-called Amitrince, 

 the complicated ventral sucker, so characteristic of the discobolous 

 fishes, has entirely disappeared, but in the genus Careproctui^, the 

 sucker has diminished so much in size and importance as to prepare us 

 for its disappearance in forms in which the same lines of degeneration 

 were pushed to an extreme. Careproctus, in fact, is intermediate be- 

 tween Liparis and Paraliparis or Amitra in the structure of the pec- 

 torals as well as on account of the reduced ventral disk. Nevertheless, 

 the genera of Liparididce are apparently so nearly related in most de- 

 tails of structure and so few in number that it matters little whether 

 subfamilies are admitted or not. If they are admitted, it will only be 

 to bring into relief the general significance of their characters and to 

 harmonize the family with others. The question whether it is best to 

 retain them may await answer until the comparative anatomy of the 

 several types is known. Meanwhile, only two subfamilies are retained,, 

 those depending on the presence or absence of the ventral sucker.
