Species 1. (Mus. Cuming.) 



Melania Henrietta. Mel. testa ovato-turritd, solidius- 

 culd, luteo-olivaced, anfractibus octo, plano-convexis, ad 

 suluras impressis, coslis subdistantibus undique regu- 

 lariter clathratis ; aperturd oblongo-ovatd, columella 

 arcuatd, ad basin expanso-effusd. 



Henrietta's Melania. Shell ovately turreted, rather 

 solid, yellowish-olive, whorls eight, flatly convex, im- 

 pressed at the sutures, regularly latticed throughout, 

 with rather distant ribs ; aperture oblong-ovate, 

 columella arched, expandedly effused at the base. 



Gray, in Griffith's Cuvier's Animal Kingdom, pi. 13. f. 2. 

 Melania reticulata, Lea. 



Hab. China. 



A shell of solid growth, latticed throughout, with 



rather distant ribs, in which the columella and aperture 



are more expandedly effused than is usual in this type of 



the genus. 



Species 2. (Fig. a, b, c, d, e, Mus. Cuming.) 



Melania asperata. Mel. testa pyramidali-turritd, elon- 

 gatd,fulvo-olivaced, anfractibus duodecim aid pluribus, 

 convexis, longitudinaliter plicato-costatis, transversim 

 liratis, litis super costas varie mnricaiortuberculutis ; 

 aperturd suborbiculari, labro utrinque sinuuto-reflexo, 

 columella arcuatd. 



The rough Melania. Shell pyramidally turreted, elon- 

 gated, fulvous-olive, whorls twelve or more, convex, 

 longitudinally plicately ribbed, transversely ridged, 

 ridges variously prickly tubercled upon the ribs ; 



aperture nearly orbicular, lip sinuously reflected on 



either side, columella arched. 

 Lamarck, Anim. sans vert. vol. viii. p. 429. 

 Hab. Philippine Islands ; Cuming. 



The largest species of the genus, extremely variable 

 in sculpture, but it may be remarked, as a general rule, 

 that in the earlier whorls the longitudinal sculpture pre- 

 dominates, whilst in the latter whorls the transverse sculp- 

 ture is the most conspicuous. 



Species 3. (Mus. Cuming.) 



Melania Pernambucensis. Mel. lesld subpyramidali- 

 turritd, solidiiisculd, olivaceo-brunned, anfractibus 

 declivi-tumidis, longitudinaliter usque ad peripheriam 

 arcuatim plicatis, transversim crebricostatis, coslis 

 super plicas elevatiusculis, inlerstitiis crispalo-granu- 

 latis, suluris excavato-impressis ; aperturd ovatd, co- 

 lumella arcuatd. 



The Pernambuco Melania. Shell somewhat pyra- 

 midally turreted, rather solid, olive-brown, whorls 

 slopingly tumid, longitudinally arcuately plicated as 

 far as the periphery, transversely closely ribbed, ribs 

 a little raised on the folds, interstices crispately 

 granuled, sutures excavately impressed ; aperture 

 ovate, columella arched. 



Hab. Pernambuco. 



A very characteristic richly-coloured shell, densely sculp- 

 tured with narrow transverse ribs, passing over concentric 

 folds, which reach only to the periphery in each whorL
