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

 (Ipsa Linnaei Conchylia, p. 2871 the name pilearis should be applied to the Mediterranean 

 Triton corrugatus Lam., and that tin- species under consideration should bear the name aquatilis 

 Reeve, uniting it. in accordance with Tryon etc. with aquatilis. As Linné says: "Habitat in M. 

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

 d small differences in the radulae of Simpulum pilearis Liri. (1. c. PI. 20, fig. 3) and 

 iquatile Reeve d.c. PI. 20, fig. 4) so I have left the name pilearis to the species generally 

 known under this nomination.
