118 NERITA. 



75. NEiUTOPSOiDES, f. 60, Recve. — Globoso-acuminata valide 

 et dense lirata, pallide fulva ; apertura superne depressa et 

 coarctata, externe subexpansa ; area columellari excavata 

 margine externo areuatim rugato, margin e interne valide 

 dentato ; labio externo crenato. — The mouth is contracted 

 near the body-whorl, but expanded outwards, and the spire 

 is elevated and rather pointed. The species otherwise very 

 nearly resembles N. erubescens. 



76. VEXiLLUM, f. 52, Reeve. — Aurantia, globoso-acuminata, 

 N. eruhescenti similis, sed nigro bifasciata, columella laevi- 

 gata. — -Were it not for the smooth columella, this species 

 might be taken for a black-banded N. erubescens. 



77. SrE?sTrLERiANA, f. 121, Recluz. — Globosa fulva Isevis, 

 breviter acuminata, apertuia subrotunda, ]?evi. — Grlobose, 

 smooth, fawn-coloured with irregular dashes of black. 



78. HELiciNoiDES, f. 73, 74, 67, Reeve. — Parva globoso- 

 acuminata, dense costata, subaurantia, maculis minutis rubris 

 et fasciis tribus nigro tessellatis ornata; apertura leevi, labio ex- 

 terno intus lirato, superne unidentato. — A pretty little species 

 of the globose-acuminated form, neatly ribbed and touched 

 with red specks, except in three dark bands which are tessel- 

 lated with black. There can be no utility in separating N. 

 'pellis-serpentis (f. 67) from this species. 



79. AFFiNis, f. 69, Reeve. — Quam N. helicinoides magis 

 elevata et contracta ; apertura multo angustiori. — More ele- 

 vated and less bulbous than the preceding. 



80. BULLULA, f. 71, Reeve. — Parva, transverse ovata, nigra, 

 anfractibus angustis'; apertura elongata labio externo subex- 

 panso, area columellari IsRvi, margine obscure dentato. — A 

 dark little smooth shell with very little character, but seem- 

 ing rather to resemble in form some of the smaller Neritince, 

 such as N. fluviatilis, &c. 



81. SAMOENSis, f. 123, 124, Dunlcer. — Parva, transverse 

 oblonga, tenuis, spiraliter costata, costis lineis nigris varie- 

 gatis ; apertura obliqua, lutea profunde excavata. — Shaped 

 like Neritina fluvlatilis and other small species, ribbed and 

 linearly speckled with grey; of a yellowish colour with deeply 

 excavated aperture.
