MELANIA.— Plate XL 



with a broad brown band, whorls ten to twelve, 

 convex, longitudinally rudely subplieated, spirally 

 grooved, the grooves becoming fainter towards the 

 aperture, sutures impressed ; aperture ovate, effused 

 at the base. 



Lea, Pro. Zool. Soc. 1850, p. 180. 



Hab. Island of Guimaras, Philippines (in small streams) ; 

 Cuming. 



"Very closely allied to the preceding species, and not 

 improbably a variety of more ventricose and less subulate 

 growth of ruder development. 



Species 64. (Mus. Cuming.) 



Melania jEREA. Mel. testa subulatd, olivaceo-virente, 

 rufo-fusco infra suturas punctata et brevi-fiammatd, 

 anfractibus undecim ad duodecim, rolundatis, superne 

 declivi-concavis, lavibus, deinde convexis spiraliter 

 lineari-sulcatis ; aperture! parviusculd, basi snbeffusd. 



The brass Melania. Shell subulate, olive-green, dotted 

 and short-flamed beneath the sutures with red-brown, 

 whorls eleven to twelve, rounded, slopingly concave 

 at the upper part, smooth, then convex, spirally li- 

 nearly grooved ; aperture rather small, slightly ef- 

 fused at the base. 



Hub. Philippine Islands ; Cuming. 



Of the same typical form as the two preceding species 

 from the same locality ; but, irrespective of a difference in 

 the contour of the whorls, the light colouring of the sutures 

 is wanting, and the linear grooves do not become obsolete. 



Species 65. (Mus. Cuming.) 

 Melania Bullioides. Mel. testa acute subulate!, livido- 

 fuscescente, olivaceo tinctd, immaculatd, anfractibus 

 undecim ad duodecim, primis fortiter plicato-costatis, 

 ceeteris ad suturas tantum plicatis, medio Icevibus, su- 

 pra et infra spiraliter lineari-sulcatis ; aperturd par- 

 viusculd, margine columellari calloso-incurvo. 

 The Bullia-like Melania. Shell sharply subulate, 

 livid-brown, tinged with olive, unspotted, whorls 

 eleven to twelve, the first strongly plicately ribbed, 

 the rest plaited only at the sutures, smooth in the 

 middle, spirally linearly grooved above and below ; 

 aperture rather small, columellar margin callously in- 

 curved. 

 llab. Philippine Islands ; Cuming. 



Chiefly distinguished from its allies of the same habitat 

 by the strongly plicated growth, and remarkable for its re- 

 semblance to a Bullia. 



Species 66. (Mus. Cuming.) 



Melania Wallacei. Mel. testa conico-subulatd, solidi- 

 usculd, intense olivaced, anfractibus decern, minute cris- 

 palis, infra suturas lineari-sulcatis, declivi-planaiis, in- 

 feme abrupte angulatis et constrictis, versus apertu- 

 ratn rotuudalis ; aperturd pand, basi subeffusd. 



Wallace's Melania. Shell conically subulate, rather 

 solid, dark-olive, whorls ten, minutely crisped, linearly 

 grooved beneath the sutures, slopingly flattened, 

 abruptly angled and constricted at the lower part, 

 rounded towards the aperture ; aperture small, ef- 

 fused at the base. 



Hab. Macassar. 



A very characteristic species, collected by that most as- 

 siduous traveller and naturalist Mr. Wallace, at Macassar. 

 Its chief peculiarity consists in the conically pyramidal 

 form of the earlier whorls, and their sudden angular con- 

 striction at the lower part. 



Pig. 67. (Mus. Cuming). 



The shell here figured is a specimen from India, of im- 

 mature growth, presenting characters which seem to pass 

 into M. corrugata. Although smooth, there are indica- 

 tions of the corrugate ribs of that species, as well as of the 

 very characteristic dark sutural band. 



Species 68. (Mus. Cuming.) 



Melania corporosa. Mel. testa ovato-subulatd, livido- 

 castaned, prope suturas lutescente, anfractibus paucis, 

 subconvexis, lemibus, minutissirne decussatim striatis, 

 versus apicem lineari-sulcatis, superne subimpressis, 

 margine funiculatis ; aperturd parviusculd, margine 

 columellari calloso-iucurvo. 



The stout Melania. Shell ovately subulate, livid- 

 chestnut, yellowish next the sutures, whorls few, 

 slightly convex, smooth, minutely decussately striated, 

 linearly grooved towards the apex, slightly impressed 

 at the upper part, corded at the margin ; aperture 

 rather small, columella]' margin callously incurved. 



Gould, MS. in Mus. Cuming. 



Hab. ? 



Mr. Cuming possesses no information of the habitat of 

 this shell. It very much resembles the M. ferrea, from 

 Borneo, but I cannot find any trace of spiral linear grooves 

 in the early whorls of that species, which is a character of 

 importance.
