222 HELIX-EULOTA. 



compressed, angulated at the suture, haviDg at the periphery an 

 obtuse, more or less exserted carina, extending to the peristome ; 

 shortly descending in front. Aperture quite diagonal, rounded- 

 tetragonal, little incised by the penultimate whorl ; peristome 

 expanded, hardly reflexed, thickened, white-lipped, the margins 

 joined by a rather thick callus. 



Alt. 10-5-13-5, diam. 14-15'5 mill. (Mlldff) 



Tenimber Is. 



Eulota (Plecteulota) goniostoma MLLDFF., N. D. M. G. 1892, p. 

 92, 1. 1, f. 4. 



Var. major. Shell larger, rufous, whorls less convex, the umbili- 

 cus narrower, aperture liver colored within. Alt. 12, diam. 16*5- 

 17 mill. (Mlldff.) 



This seems nearest to the Australian forms duralensis Cox, 

 pliculosa Pfr., and also E. occulta of the Aru Is. It is rather varia- 

 ble in color, altitude of spire and prominence of the carina. The 

 keel is never entirely lacking, but is often only a rounded, weak 

 cord, which in extreme forms (forma carinata) becomes strongly 

 projecting, and is continued to the aperture.

Shell narrowly but perspectively umbilicated, depressed, solid, 

 having delicate, curved plicate-striatulate sculpture, the cuticle very 

 thin, deciduous, seen under a strong lens to be densely punctate 

 and covered with microscopic hairs; having a frosty appearance, 

 opaque, buff-horn colored. Spire depressed-conoid. Whorls 4J, 

 slightly convex, slowly increasing, separated by an appressed, mar- 

 gined suture, the last whorl begirt at the periphery with an obtuse 

 but distinctly projecting carina ; subinflated below, roundly angled 

 around the umbilicus, shortly deflexed at the aperture, coarctate. 

 Aperture diagonal, truncate-elliptical, the peristome broadly 

 expanded, everywhere reflexed, rather thick, rose-lipped, the mar- 

 gins a little converging, joined by a distinct callus, columellar mar- 

 gin strongly dilated above, partly covering the umbilicus. 



Alt. 9-8-11-25, diam. 16-5-19 mill. ; aperture width 10'5, long. 8- 

 9-5, alt. 5-6-5 mill. (Mlldff.)
