Closely resembles small specimens of P. heterostropha, though 

 in size and texture it is like P. fontinalis, which has a much 

 shorter spire. 



Melania Cybele. Testa ovata, turrita, crassa, fuliginosa, epi- 

 dermide velutino induta ; spira ad apicem valde erosa, anfr. 

 superstit. ad 3 planulatis, superne tabulatis, et pinnis curtis acu- 

 tis arrectis ordinatim dispositis, coronatis : apertura angusta, 

 elongato-ovalis, postice angulata ; intus livida. Long. 1, lat. f 

 poll. Hab. Feejees, Navigators, &c. 



Probably confounded with M. amarula. That shell is lighter 

 colored, shorter, smoother and destitute of the velvety epidermis : 

 the spines are less numerous, longer and sharper and stand out 

 somewhat from a vertical position : in this species they resemble 

 mural battlements. 



Melania tetrica. Testa oblonga, turrita, ponderosa, fusca, 

 liris paucis cincta : spira truncata, anfr. superstitibus 3-4 convex- 

 iusculis, postice sub-angulatis et spinis validis acutis 5 ad basim 

 decurrentibus armatis, interdum muticis : sutura profunda : aper- 

 tura arete elliptica ; intus livida. Long. 1^, lat. f- poll. Hab. 

 Feejee Islands. 



More slender than the preceding, and with more convex whorls. 

 It has nearly the same form as M. bellicosa, Hinds, but is larger 

 and has fewer spines. It is especially distinguished by its few 

 stout spines directed outwards. 



Melania Terpsichore. Testa elongato-turrita, solidula, oli- 

 vacea, plagis flexuosis fuscis picta, longitudinaliter creberrime 

 plicata, et liris elevatis versus basim crescentibus cincta : spira 

 elevata, ad apicem erosa, anfr. 4 postice subangulatis : apertura 

 angusta, elliptica, testse longitudinis trientem adequans ; intus 

 coerulescens. Long. 1, lat. § 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. 



Melania corolla. Testa parva, ovato-conica, fusca : spira 

 acuta, anfr. ad 6 ventricosis, postice constrictis, angulo submedi-
