According to Mérch (J. Conchyl. xm. p. 395) this species ‘‘dépose ses ceufs 
dans l’ombilic.” 
The teeth or lamella seem to be variable ; some specimens shew traces of a second 
tooth in the upper portion of the outer lip, thus having nine teeth in all. Considerable 
variation is also shewn in the relative proportions of height and breadth, and in the 
width of the umbilicus.

(3) Lxdodonta laminata Pease. 
Flelix laminata Pease, Amer. J. Conch. 1. (1866), p. 292. 
According to the diagnosis this differs from the last by being spirally sculptured 
as well as transversely ribbed, thereby becoming decussated. The teeth appear to 
be identical in number and position and I believe it will, eventually, only prove to be a 
local race. 
Tryon (Man. Conch. Ser. 2, m1. p. 70) considered it to be a form of £. cavernula, 
Hombr. and Jacq., stating “I have before me two trays of shells named Hedex 
laminata Pease, from the ‘Sandwich Is.,’ one of them from the describer, which 
undoubtedly represent the same species.” Since the two forms differ, from the 
diagnoses, so widely in the armature, there must, I think, be some error.
