compressa nel genere Facelina ", but he does not suggest where it 

 should be placed. 



The original description is incomplete, and the illustration also 

 is not good, but the form does not appear to have been found 

 subsequently, and so we have only this to go upon. In the absence 

 of further details, particularly of the radula, it is hardly possible 

 to place this form accurately, but in the possession of fine oral 

 tentacles, produced angles on the foot, and feebly perfoliate 

 rhinophores, it agrees Avith certain members of the genus Goryphella. 

 Pending its rediscovery and more accurate description, it would 

 seem advisable to include it in this genus. 



The classification and synonymy of this form is therefore as 

 follows : —
