Melania brevior. Mel. testa obeso-conicd, crassd, oli- 

 vaceo-nigrd, intus earulescente, anfractibus paucis, con- 

 vexis, undique dense profundi sulcatis, versus apicem 

 concent rice suhplicatis, suturis subimpressis ; aperturd 

 subquadrato-ovatd, utrinque sinuatd. 



The shorter Melania. Shell stoutly conical, tliick, 

 olive-black, bluish within, whorls few, convex, closely 

 deeply grooved throughout, faintly concentrically pli- 

 cated towards the apex, sutures rather impressed ; 

 aperture somewhat squarely ovate, sinuated at each 

 end. 



Troschel, in Schomburgk's 'Travels in British Guiana,' 

 vol. ii. p. 550. 



Hab. Rio Branca, Guiana ; Yates. 



A shortly convoluted shell, of solid growth, encircled 

 throughout with deep close-set grooves, the upper whorls 

 being faintly concentrically plicated. 



Species 198. (Mus. Cuming.) 



Melania loricata. Mel. testa elongato-turritd, solidi- 

 usculd, nigra, intus earulescenle, anfractibus subnume- 

 rosis, declivi-planatis, undique plicatim tuberculato- 

 granatis, suturis teunicarinatif, auj'ractu ultimo inferne 

 dense spiraliter carinato ; aperturd ovatd, pared, utrin- 

 que sinuatd. 



The armour-clad Melania. Shell elongately turreted, 

 rather solid, black, blue in the interior, whorls rather 

 numerous, slopingly flattened, plicately tubereularly 

 grained throughout, sutures finely keeled, last whorl 

 densely spirally keeled at the lower part ; aperture 

 ovate, small, sinuated at both ends. 



Hab. ? 



This elongately turreted species is of rather solid growth, 

 covered with a strongly sculptured armour of tubercular 

 grains. Although its habitat is not known, there can be 

 little doubt of its being from Brazil. 



Species 199. (Mus. Cuming.) 



Melania sdbimbricata. Mel. testa elongato-turritd, 

 tenuiculd, olivaceo-nigrd, anfractibus subnumerosis, de- 

 clivi-planatis, partial coucavis, lougiludiualiler cou- 



ceutrice costulatis, coslulis angnstis, inferstitiis liris 

 tenuibus spiralibus nilide cancellatis ; aperturd parvd, 

 rotundatd, utrinque sinuatd. 



The finely-imbricated Melania. Shell elongately 

 turreted, rather thin, olive-black, whorls rather nu- 

 merous, slopingly flattened, concave in part, longitu- 

 dinally concentrically ribbed, ribs narrow, interstices 

 neatly cancellated with fine spiral ridges ; aperture 

 small, rounded, sinuated at each end.

 5. f. 3. 



Hub. Brazil. 



One of the most narrowly elongated of the Brazilian 

 species, very neatly sculptured throughout with curved 

 longitudinal fine ribs, following in regular concentric order, 

 neatly cancellated in the interstices. 



Species 200. (Fig. a, b, c, Mus. Cuming.) 



Melania fusca. Mel. testa pyramidali-turritd, solidis- 

 simd, fn.lvo-castaned, anfractibus noveni ad decern, 

 primis pancis oblique granoso-plicatis, caleris spira- 

 liter liralis, et conspicue acute bicari.uatis, carinis dis- 

 tantibus; aperturd ovatd, utrinque sinuatd. 



The brown Melania. Shell pyramidally turreted, very 

 solid, fulvous-chestnut, whorls nine to ten, the first 

 few obliquely granosely plicated, the rest spirally 

 ridged, and conspicuously sharply two-keeled, keels 

 distant; aperture ovate, sinuated at each end. 



Murex fumes, Gmeliu, Syst. Nat. p. 3561. 



Hab. Senegal. 



A solid, pyramidally turreted shell, remarkably charac- 

 terized by the prominence of winding keels, which are not 

 present in the early whorls, their place being occupied by 

 oblique folds of well-defined granules. 



Species 201. (Mus. Cuming.) 



Melania scarabus. Mel. testa ovalo-conicd, versus ba- 

 sin obeso-fjibbosd, crassissimd, intense nigra, anfracti- 

 bus perpaucis, decUvi-convexis, undique creberrime sul- 

 catis, liris obsolete striato-crenulatis, auj'ractu ultimo
