108 NERITA. 



16. BiSECTA, f. 56, 57, Reeve. — Quam N. Antillarummsigiii 

 expansa, area columellari lasvigata, frequenter flavida, costis 

 medio longitudinaliter divisis. — Of a broader and flatter make 

 than the preceding ; smoother in the columellar area, which 

 is sometimes yellow, and the ribs are split, as it were, in the 

 middle by an incised line. 



17. DoMBETi, f. 109, Recluz. — Parva, subrotunda, dense 

 spiraliter costata fulvo-griseavel nigrescens ; apertura expansa, 

 labio superne extenso columella concavo-excavata ; area colu- 

 mellari plannlatim excavata subgrannlosa, macula cserulea 

 vel nigra picta. — A rather rounded shell, with fine ribs and 

 expanded mouth, with a bluish-black spot on the columellar 

 area. Fig. 85 represents a darker shell, which can hardly 

 be distinguished from the type. 



18. GEORGiNA, f. 110, 111, Recluz. — Oblique ovata sub- 

 oblonga, costellis acutis, subdistantibus nigro articulatis, fre- 

 quenter duplicatis; area columellari polita vix medio dentata; 

 labio externo tenui, crenulato. — The ribs are a little distant, 

 sharp-edged, and articulated with black ; the mouth is smooth, 

 and the edge of the outer lip not nearly so much notched as 

 in the figure which was copied before seeing specimen. 



19. GBANULATA, f. 66, Rceve. — Quam N. Domheyi brevior, 

 liris magis distantibus; area columellari valide granulata, 

 labio externo intus valide plicato. — Eemarkable for the 

 strong granulation of the columellar area and the strong 

 plaits inside the outer lip. 



20. NovyE-G^uiNE^, f. 116, 117, Lesson. — Subglobosa 

 grisea nigricans, spiraliter confertim filoso-lirata ; columella 

 ad marginem valide dentata ; spira parva exserta aurantia 

 acuminata. — This species has not the flattened spire of the 

 several preceding ; it has strong teeth on the columella, and is 

 somewhat fluted on the edge of the outer lip. 



21. Bernhaedi, f. 104, 105, Recluz. — Parva, rude spi- 

 raliter costata, flavida, nigro late variegata, et albizonata ; 

 area columellari angusta, gianulata, labio externo intus 

 valide crenato. — This is a smalJ bhell, rather coarsely ribbed, 

 covered, except in one or muje bands, with mottled black. 

 The columellar area is narrow and strongly granulated. 



22. genuana, f. 117, 118, Raeve. — Quam N. Bernhardi 

 magis globosa, spira subplanata, apertura baud tantum ex-
