should be placed ; but with the columellar lip not at all tumid, 

 the spire more produced, and having a much stronger excavation 

 near the suture. 



114. Neritina Gtjinerii (pi. cxvi. f. 272), Recluz, MS. 



N. testa transverse subovali, soHda, nigra, transverse striata ; 

 spira depressa, apice planulato ; apertura magna, flavidu ; labio 

 interno planulato, minute dentato ; labio externo subexpanso. 



Rather sohd, black, transversely striated, of an oval form, with 

 depressed spire, and should come near N. Morio (Sp. 24). The 

 aperture is yellow, with the inner lip flat, the outer lip rather 

 expanded.

N. testa transverse subovali, nigra, Isevi ; spira depressa, apice 

 piano; apertura magna, cseralea; labio interno Isevi, planulato; 

 labio externo subexpanso. 



Less solid than N. Guinerii (Sp. 114), and should be placed 

 with it near N. Morio (Sp. 24). The aperture is blue, with the 

 inner lip quite flat and smooth, and the outer lip expanded and 

 shghtly angular near the lower edge; the external surface is 

 smooth and black.

116. Neritina solidissima (pi. cxvi.f. 273), Sowerb?/,Jtmr., 

 Pro. Zool. Soc, 1849. 



N. testa subglobosa, solida, nigra, transverse striata; spira 

 depressa, apice planulato; apertura magna, alba; labio interno 

 planulato, margine recto, dentato ; labio externo superne et inferne 

 expanso, subangulato, intus incrassato. 



Tliis species presents the idea of K cariosa (Sp. 3), in an early 

 stage of growth before the full expansion of the outer hp ; it is, 

 however, a much more solid shell; the iimer lip is flat, and the 

 outer lip thickened within.
