Plate IV. 



Species 15. (Mus. Cuming.) 



Melania haurula. Mel. testa turriculatd, nigricante- 

 fuscti, anfractibus convexis, superne anguste excavatis, 

 deinde liratis, liris suhobscuris ; apertura parvd, ra- 

 fescente. 



The little Mooe Melania. Shell turriculated, black- 

 ish-brown, rather solid, whorls convex, narrowly ex- 

 cavated round the upper part, then ridged, ridges 

 somewhat obscure ; aperture small, tinged with red. 



Hah. South-east coast of Guinea. 



A rather narrowly turriculated shell, of solid growth, 

 obscurely spirally ridged throughout, the upper margin of 

 the whorls being lightly narrowly excavated. 



Species 16. (Mus. Cuming.) 



Melania blatta. Mel. testa subidatd, ad basin sub- 

 trnncatd el clavatd, solidiusculd. laevigata, olivaceo- 

 nigrd, anfractibus novem ad decern, planatis, ad sutu- 

 ras marginalia, anfractibus panels, primis longitudina- 

 liter plicato-costatis, costis confertis, de siduris decur- 

 rentibus ; apertura ovatd, ad basin hdiusculd, mar- 

 gine colmneUari late calloso-planato. 



The beetle Melania. Shell subulate, somewhat trun- 

 cated and club-shaped at the base, rather solid, 

 smooth, olive-black, whorls nine to ten, flat, mar- 

 gined at the sutures, the first few whorls longitudi- 

 nally plicately ribbed, ribs close-set, running from 

 the sutures ; aperture ovate, rather broad at the base, 

 columellar edge broadly callously flattened. 



Lea, Pro. Zool. Soc. 1850, p. 184. 



Nab. Ibu, province of Zambales, Island of Luzon, Philip- 

 pines (in a rapid river, and in rivulets) ; Cuming. 



In this species we have a distinct type of Melania, 

 broadly truncate at the base, with the columellar margin 

 of the aperture pressed inwardly to a broad flattened 

 callosity. The whorls are not excavated round the upper 

 part ; the ribs run down from the extreme margin of the 

 sutures. 



Species 17. (Mus. V. d. Busch.) 

 Melania antiiracina. Mel. testa subidatd, subacicu- 

 lari, solidiusculd, nigra, ad basin subclavatd, anfrac- 

 tibus plano-convexis, spiru/ifer inciso-striatis, dense 

 plicalo-liratis, liris de siduris decurrentibus, versus 



aperturam gradatim obso/etis; apertura ovatu, parri- 

 nsculd, ad basin subproductd, margine columellari cal- 

 loso-planatd. 



The coal-black Melania. Shell subulate, somewhat 

 acicular, rather solid, black, somewhat club-shaped, 

 whorls flatly convex, spirally incisely striated, densely 

 plicately ridged, ridges running down from the su- 

 tures, becoming obsolete towards the aperture ; aper- 

 ture ovate, rather small, a little produced at the base, 

 columellar margin callously flattened.

llab. ? 



Of the same type as the preceding species, but quite 

 distinct in its specific characters. The columellar margin 

 is less callous, and the aperture is slightly produced at the 

 base ; the longitudinal sculpture is finer, and of a different 

 kind, whilst the whorls are encircled with engraved strife. 



M. funiculus of MM. Quoy and Gaimard, in Zool. Voy. 

 de l'Astrolabe, might be this or the preceding species ac- 

 cording to the figure, but the description does not agree 

 with either. 



Species 18. (Mus. Cuming.) 



Melania circumstriata. Mel. testa turritd, solidd, 

 hifio-olivaced aid fused, anfractibm convexis, superne 

 paululum constrictis, striis elevatis undique spiraliter 

 funiculatis, longitudinaliter valide costatis, costis sub- 

 distantibus, versus aperturam obsoletis ; apertura ova- 

 td, ad basin vix productd. 



The striae-encircled Melania. Shell turreted, solid, 

 yellowish-olive or brown, whorls convex, a little con- 

 tracted at the upper part, spirally corded throughout 

 with raised striae, longitudinally strongly ribbed, ribs 

 somewhat distant, obsolete towards the aperture ; 

 aperture ovate, scarcely produced at the base. 



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



llab. Borneo. 



Taking a rather broad view of the modifications of a 

 species known to be of the most variable character, con- 

 sequent on its wide geographical distribution, this might 

 be pronounced to be the Borneo representative of the M. 

 asperata of the Philippines.
