98 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 16 



Remarks: This species, in general appearance, most resembles F. 

 alabastrum Moseley, but the apical angle is only about one-third that of 

 that species and in addition the calice is not nearly as compressed later- 

 ally. F. deludens von Marenzeller is another allied species but its apical 

 angle is 120-180°. 



If the present interpretation of the wall of these specimens as being 

 eroded is incorrect, then this species should be referred to some other 

 genus and family. 



Dimensions of holotype: Height 15 mm, calice 8.0 by 9.5 mm, 

 fossula 1.5 mm wide near top, pinching out below, 3 mm long, 8 mm 

 deep. 



Holotype: AHF no. 22, with one paratype. 



Type locality: Sta. 1348-41, Tanner Bank, 45-46 fms. 



Material examined: The types.
