" This little species, which has some affinity to C. triliratus, Pfr., 

 is singular on account of the incision which appears in the 

 parietal margin near its junction with the right lip, a feature not 

 observed in any other species of the Cyclostomacea. It is M-ith 

 some hesitation thei'efore that, in the absence' of an operculum, 

 I refer it to Cydopliorns, although the general habit of the shell 

 bears out the location." (^Benson.)
