Kesteven (Proc. Linn. Soc. N. South Wales, 1902, p. 476) says that according to Hanley, 

 (Ipsa Linnaei Conchyha, p. 287) the name pilearis should be applied to the Mediterranean 

 Triton corrti-gattcs Lam., and that the species under consideration should bear the name aqiiatilis 

 Reeve, uniting it, in accordance with Tryon etc. with aqtcatilis. As Linn£ says : " Habitat in M. 

 Mediterraneo", this view may be in so far right. But Troschel (Gebiss der Schnecken I, p. 234) 

 has observed small differences in the radulae of Simptilum pilearis Lin. (I. c. PL 20, fig. 3) and 

 >S. aqtiatile Reeve (I.e. PL 20, fig. 4) so I have left the name pilearis to the species generally 

 known under this nomination.

As already stated, Pilsbry unites~this form with the preceding species as a synonym, as 

 he finds no characters by which to separate them. I have never found difficulty in distinguishing 

 this species.
