within the Åmphiuridae, it certainly does seem very inappropriate 
to unite, in this genus alone, species which, after the character 
of their oral structures, should otherwise be referred partly to Åmphi- 
oplus, partly to Åmphiura s. str. 
The discovery oF this new species, so closely agreeing with the 
type of the genus Ophionephthys in the important characters of the 
mouth parts, decidedly lends support to a restriction of the genus 
Ophionephthys to those species agreeing with the type, O. limicola, 
in regard to the oral characters. Besides the new species here 
described I would refer to this genus also the species described by 
H. Lym. Clark (Catalogue Rec. Oph. p. 253) under the name of 
Åmphioplus cyrtacanthus (from the Philippines). The genus would 
thus also get a less remarkable geographical distribution. The 
other species referred by Clark to Ophionephthys I cannot, ac- 
cordingly, regard as really belonging to that genus.
