NERITA. 107 



rucose. The darker shell, f. 55, is a little differently shaped, 

 and more generally black. 



10. LiNEATA, f. 38, Chemnitz. — Oblique oblonga, costellis 

 nigris dense spiraliter cincta ; spira compressiuscula, anfrac- 

 tibus versus suturam tumidiusculis, turn declivi-depressis ; 

 apertura ampla aureo suffusa, labio interno subrugoso, ad 

 marginem valide dentato. — Having the same obliquely-oval 

 form as all the preceding species, and spirally girt with out- 

 standing black ridges. The columellar area is more or less 

 tinctured with yellow. 



11. BALTEATA, f. 83, Reeve. — Quam N. lineata magis 

 angustata, liris spiralibus magis distantibus, hinc illinc albo- 

 punctatis, labio externo intus crenato, area columellari verru- 

 cosa, margine valide dentato. — More nari'ow than iV. lineata, 

 with the spiral lines more distant and articulated. 



12. ATRAMENTOSA, f. 44, Reeve. — Anguste oblonga, lineis 

 nigris albo punctatis spiraliter dense cincta ; area colu- 

 mellari subrugata, margine valide dentato ; labio externo 

 nigro marginato, intus crenato, supra infraque valide uni- 

 dentato. — Of a blackish-grey colour, with finely speckled 

 close linear ridges. A strong lateral tooth above and one 

 below on the inner surface of the outer lip. 



13. BiRMANiCA, f. 82, Philipjpi. — Quam N. atramentosa 

 magis regulariter ovata, liris punctatis spiralibus vix elevatis; 

 spira minutissima, dentibus lateralibus in apertura ob- 

 soletis. — The spiral ribs are very little raised, the form is an 

 oblique regular oval, and the upper and lower lateral teeth 

 in the aperture, conspicuous in the preceding, are obsolete in 

 this species. 



14. STRICTA, f. 118, Baird. — May be identical with the 

 preceding, but I have only a rough sketch and notes. 



15. Antillarum, f. 53, 54, Gmelin. — Nigrescens, sub- 

 quadratim ovata, costis complanatis, concentrice striatis, 

 approximatis sculpta ; apertura ovata, area columellari 

 granulosa margine valide dentato, labio externo intus 

 crenato. — There can be little doubt that this is the species 

 referred to in the figure of Chemnitz, pi. 192, f. 1987, named 

 scalpta in Reeve's work and insculpta in the British 

 Museum. It is characterised by broad flat ribs, set rather 

 closely together.
