^^ery abundant and restricted to Borabora and Maupiti, where they live on the 
ground in forests. 
AVhen I wrote my description of this species I had only half a dozen specimens of 
Boraborensis named from Pease’s types. Plaving subsequently gathered several 
hundred of the latter species at Borabora, I find the two species gradually intergrade. 
Maupiti specimens are remarkably uniform in shape, sculpture and coloration. The 
Borabora shells, on the contrary, are subject to considerable variation in all the above 
characters. In order to incorporate the characters of .the latter, I rede.scribe it as 
follows : — 
Shell widely umbilicated ; depressed, lenticular, rather thin, corneous or brownish 
bom-color, irregularly spotted and rayed with rufus-brown, rarely unicolored; sculpture 
consisting of very small, rude, crowded, oblique, subarcuate, raised stri®, with remote 
larger ones intermixed ; the latter sometimes absent in the Borabora shells, and in the 
immature they are frequently membraneous and lacerated ; spire more or less con^•ex 
sometimes nearly planulate, rarely depressly conoid; apex mucronated, generally,’ 
suture lightly impressed, occasionally margined by the continuation of the periphery- 
keel. Whorls 5|-7l, convex or subplanulate, very narrow, slowly and re^mlariv 
increasing, last one not deflected in front, rarely sulcate above, periphery Cutely 
bj more or less dislinctly angulate, rarely rounded; umbilicus funnel- 
drapr'd, a little more than a third the greater diameter of the shell. .Vpr.rturc oblinue
