plicata, et liris elevatis versus basim crescenlibus cincta : spira 

 elevata, ad apicern erosa, anfr. 4 poslice subangulatis : apertura 

 angusta, elliptica, tesla3 longitudinis trientem adequans ; intus 

 ccerulescens. Long. 1, lat. f poll. Hab. Feejee and Samoa 

 Islands. 



Of the same group as the preceding, but more slender, and 

 remarkable for the lyrate appearance produced by its numerous 

 folds, decussated by revolving lines, one of which, more conspi- 

 cuous than the rest, forms a sort of beaded angle.

 Lat. y-j, alt. Y^y- poll. Hah. Banks' Peninsula, New Zealand. 



This beautiful little shell, somewhat resembling M. spinulosa, 

 is readily recognized by its coronets of numerous small radiating 

 prickles on the angles of the whorls. 



Melania lutosa. Testa crassa, elongato-turrita, striis tenui- 

 bus cincta, fLisco-castanea,et crusta Isevi, lutosa, crassa, rubigino- 

 sa, omnino obtecta : spira anfr. 7 superstitibus convexis ; sutura 

 profunda : apertura obovata, vix effusa, peristomate rufo limbato ; 

 fauce livido : operculum crassum, osseum, subspirale. Lat. J-, 

 alt. If poll. Hab. Upolu. 



This simple and graceful shell, resembling in form M. Virgi- 

 nica or M. decoJIala., is easily distinguished by the dark brown 

 margin of the aperture. It is remarkable for the thick crust of 

 mud with which it is covered, and which is so smooth and brown 

 externally, as to seem like the natural surface of the shell. A 

 glance at the tip reveals its real nature. 



Melania corporosa. Testa subulato-conica, decollata, niti- 

 da, olivaceo-castanea, juxta suturam cerina, striis plerumque mini- 

 mis decussata : spira anfr. ad 5 convexiusculis ; sutura profunda 

 et marginata : apertura angusta, pyriformis, antice vix producta ; 

 intus livida ; columella albida. Long. 1^, lat. J- poll. Hab. 

 Taheiti. 



Very nearly the same shape as M. lutosa, but is distinguished by 

 its clean, shining, minutely reticulated surface, its pale sutural re- 

 gion, and its narrower aperture, destitute of the deep brown limbus.
