The Rotatorian Genus Diaschiza. 141 



D. fretalis Gosse. — Another very vague description. This 

 species, being marine, may be a marine form of D. Hoodii. 



D. acronota Gosse 1 All these are certainly imma- 



D. PjETA Gosse V ture or dead specimens of D. 



Furcularia ensifera GosseJ caeca Gosse. 



D. semiaperta Gosse = D. gibba (nobis) = F. gibba Ehrenberg. 



F. spHjERICA Gosse = D. globata Gosse. 



F. lophyra Gosse. — This may be a fair species, and if so, it is 

 a Diaschiza ; its frontal eye will distinguish it from D. eva, but 

 the description is very vague. 



F. gammari Plate | The description of all these ies

F. melandocus Gosse V f 4 for identificati ^ 



F. molaris Gosse ) & 



F. lactistes Gosse. — This description is, again, a difficult one 

 from which to identify. It has a certain agreement with 

 D. megalocephala Glascott, which we have inserted in the 

 monograph under protest. 



It is very likely that a new genus may one day be established 

 in which it is probable that lactistes will take precedence over Miss 

 Glascott's Furcularia megalocephala.
