Plate XXXII. 



Species 209. (Mus. V. d. Busch.) 



Melania acicularis. Mel. testa subulatd, solidiusculd, 

 nigricante-fuscd, lavigatd vel spirdliter tenuistriaid, 

 anfractibus octo ad novem, super tie concaviusculis, 

 delude declivi-planatis ; aperturd parvd, ad basin si- 

 uitatd, columella sabcallosd, ad basin tenue conlorld, 

 callosilute fumeo-pnrpurascente. 



The acicular Melania. Shell subulate, rather solid, 

 blackish-brown, smooth or spirally finely striated, 

 whorls eight to nine, slightly concave round the 

 upper part, then slopingly flattened ; aperture small, 

 sinuated at the base, columella rather callous, thinly 

 twisted at the base, callosity smoky-purple. 



Melanopsis acicularis, Pfeitfer, Rossmasler, Icon. vol. ii. 

 pi. 50. f. 673 to 675. 



This shell partakes of the characters of all three genera, 

 Melania, Melanopsis, and Remisinus, and may be referred 

 with equal propriety to either. 



Species 210. (Mus. Cuming.) 



Melania nucula. Mel. testa ovato-conoided, solidius- 

 culd, olivaced, anfractibus sex ad septan, plano-decli- 

 vibus, ad suturas subangulatis ; aperturd ovatd, colu- 

 mella tenue rejlexd, purpurascente, ad basin subeffusd. 

 The little nut Melania. Shell ovately conoid, rather 

 solid, olive, whorls six to seven, flatly sloping, slightly 

 angled at the suture ; aperture ovate, columella thinly 

 reflected, purplish, slightly effused at the base. 

 Hab. New Caledonia. 



A small conoid type, of few whorls, peculiar to the ha- 

 bitat, of which another form, M. crassilabruin, is described 

 in Plate XXXIII. at Sp. 221. 



Species 211. (Mus. Cuming.) 



Melania denticulata. Mel. testa ovato-turriid, te- 

 nuiculd, fv.lvo-fv.scd, epidermide subpilosd iudutd, an- 

 fractibus paucis, spirdliter dense irregulariter lira/o- 

 striatis, superne late angulatis, ad unguium remote 

 minute muricalo-plicatis ; aperturd ovatd, columella 

 tenuissime rejlexd. 



The toothed Melania. Shell ovately turreted, rather 

 thin, fulvous-brown, covered with a slightly hairy 

 epidermis, whorls few, spirally densely irregularly 

 ridge-striated, broadly angled round the upper part, 



distantly minutely prickly plicated on the angle ; 



aperture ovate, columella very thinly reflected. 

 Lea, MS. in Mus. Cuming. 

 Hab. Island of Negros, Philippines (in mountain streams); 



Cuming. 



I figure this shell as named by Mr. Lea in Mr. Cuming's 

 collection, but doubt if it is anything more than a variety 

 of M. scabra. 



Species 212. (Mus. Hamilton.) 



Melania Metcalfei. Mel. testa snbulato-turritd, nigra 

 aut viresceute-fuscd, ititerdum purpureo-uigro obscure 

 strigatd, anfractibus novem ad decent, plano-dectioibus, 

 spiral iter lirato-funiculatis, I iris versus apicem vali- 

 dis, versus aperturam subevauidis, irregularibus, su- 

 turd distinctd, excavatd ; aperturd parviusculd, ad 

 basin rotundato-ejf'usd. 



Metcalfe's Melania. Shell subulately turreted, black 

 or greenish-brown, sometimes obscurely streaked with 

 purple-black, whorls nine to ten, flatly sloping, spi- 

 rally corded with ridges, ridges towards the apex 

 strong, towards the aperture somewhat fading and 

 irregular, suture distinct, excavated ; aperture rather 

 small, rotundately effused. 



Melania subsuturalis, Metcalfe, Pro. Zool. Soc. 1851, p. 73. 



Hab. Borneo. 



I feel it absolutely necessary to alter the name of this 

 species. By some inadvertence Mr. Metcalfe named it 

 subsuturalis, which means 'slightly or indistinctly sutured.' 

 The special peculiarity of the shell is in the suture being 

 unusually deep, as Mr. Metcalfe himself describes it : "su- 

 turd distinctd, excavatd." 



Species 213. (Mus. Cuming.) 



Melania datura. Mel. testa oblongo-pyramidali, fusco- 

 nigrd, anfractibus paucis, spirdliter acute liratis el 

 stria/is, superne late concavo-angulatis, ad unguium 

 loui/ispiuosis ; aperturd parviusculd, fauce carules- 

 cente, columella tenui, vix rejlexd. 



The given Melania. Shell oblong-pyramidal, fuscous- 

 black, whorls few, spirally sharply ridged and stri- 

 ated, broadly eoncavely angled at the upper part, 

 long-spined at the angle ; aperture rather small, in- 

 terior bluish, columella thin, scarcely reflected. 



May, 1860.
