MELANIA.— Plate XIV. 



angle, and the flamed painting, which is generally on the 

 upper part of the whorls, is in this species at the lower. 



Species 94. (Mus. Cuming.) 



Melania UNISULCATA. Mel. testa acute subulatd, pal- 

 lide olivacea, rufo-fusco versus apicem minute punctata 

 et undulatd, anfractibus duodecim, pluuulatis, lavi- 

 bus, ad suluras uni-sulcatis ; apertura sitbangustd. 



The one-grooved Melania. Shell sharply subulate, 

 pale-olive, dotted and minutely waved towards the 

 apex with red-brown, whorls twelve, flattened, smooth, 

 one-grooved at the sutures ; aperture rather narrow. 



Hab. ? 



A slenderly acuminated shell, with one striking charac- 

 teristic. A single liuear groove is formed on the body of 

 each whorl, in the place of the suture. 



Species 95. (Mus. Cuming.) 



Melania uniforjiis. Mel. testa acute aciculari, oliva- 

 cea, purpureo-castaneo obscure fiammatd et vittatd, an- 

 fractihus tredecim ad quatuordecim, declivi-plaiadatis, 

 longitudinaliter valide plicatis, spiraliter lineari-sul- 

 catis ; apertura ovatd, calloso-incurvd. 



The uniform Melania. Shell sharply acicular, olive, 

 obscurely flamed and filleted with purple-chestnut, 

 whorls thirteen to fourteen, slopingly flattened, longi- 

 tudinally strongly plicated, spirally linearly grooved ; 

 aperture ovate, callously incurved. 



Quoy and Gaijiard, Zool. Voy. de l'Astrolabe, vol. iii. 

 p. 154. pi. 5(i. f. 30-33. 



Hali. Celebes. 



A slenderly acicular shell, strongly longitudinally plaited, 

 the plaits being cut through at regular intervals by spiral 

 liuear grooves. The painting is peculiar in consisting of 

 numerous interrupted fillets, as well as longitudinal flames. 



Species 96. (Mus. Cuming.) 



Melania Bensoni. Mel. testa ovato-turritd, solidiuscu- 

 la, olivaceo-fuscd, anfractibus quinque ad sex, rotun- 

 datis, concent rice ji/icalo-cos/atis, spiraliter lineari-li- 

 ratis, /iris versus basin plus minusve obsoletis ; aper- 

 tura ovatd, subeffusd. 



Benson's Melania. Shell ovately turreted, rather solid, 

 olive-brown, whorls five to six, rounded, concentri- 

 cally plicately ribbed, spirally linearly ridged, ridges 

 more or less obsolete towards the base ; aperture 

 ovate, a little effused. 



Melania caucellata, Benson (not of Say). 

 Hab. India. 



A rather short stout species, encircled throughout with 

 fine, corded ridges, but characterized chiefly by a succession 

 of concentrically arched, rib-like folds. 



Species 97. (Mus. Cuming.) 



Melania Fortunei. Mel. testa turriculatd, olivaceo- 

 vireute, anfractibus novem ad decern, subangustis, con- 

 vexis, spiraliter lineari-sulcalis, concentrice valide pli- 

 catis, aufractu ultimo ad basin iricarinalo, interstitiis 

 excavatis ; apertura pand, subrotundatd. 



Fortune's Melania. Shell turriculated, olive-green, 

 whorls nine to ten, rather narrow, convex, spirally li- 

 nearly ridged, concentrically strongly plicated, last 

 whorl three-keeled at the base, interstices excavated ; 

 aperture small, somewhat rounded. 



Hab. Shanghai, China ; Fortune. 



Of the same type as the preceding species, with the 

 whorls narrower and more numerous, forming a shell of 

 more slender convolution. The chief distinguishing fea- 

 ture is at the base of the last whorl, which is strongly 

 three-keeled, the interstices between them being quite 

 concave. 



Species 98. (Mus. Cuming.) 



Melania costellaris. Mel. testa pyranddali-turritd, 

 solidd, tenebroso-olivaced, versus apicem castaneo ob- 

 scure fiammatd, anfractibus decent, plano-convexis, pri- 

 mis spiraliter linear i-sulcatis, ccsteris gradatim lavi- 

 bus, superne concavo-angulatis, deinde valide plicato- 

 costatis ; apertura ovatd. 



The costellated Melania. Shell pyramidally tur- 

 reted, solid, dark-olive, obscurely flamed towards the 

 apex with chestnut, whorls ten, flatly convex, the 

 first spirally linearly grooved, the rest gradually 

 smooth, concavely angled at the upper part, then 

 strongly plicately ribbed ; aperture ovate.

Hab. Islands of Negros, Tanhay, and Siquijor, Philippines 

 (in small streams) ; Cuming. 



Remarkable for the change which the shell undergoes 

 in form and sculpture as it advances in growth. The 

 earlier whorls are simply spirally grooved, these gradually 

 become obsolete, and the whorls push out at the upper 

 part into an angular shelf, and are strongly plicately 

 ribbed.
