MELANIA.— Plate III. 



Species 13. (Mus. Cuming.) 



Melania plicata. Mel. testa, turritd, olivaceo-castaned, 

 anfractibm superne declivi-angnlatis, deinde longitudi- 

 naliter plicatis, pl/cis ad angulum muricatis, anfractus 

 ultimi parte inferiori remote spiraliter liratd ; aper- 

 turd ovatd, ad basin subprodnctd. 



The plaited Melania. Shell turreted, olive-chestnut, 

 whorls slopingly angled round the upper part, then 

 longitudinally plicated, plaits prickly on the angle, 

 lower part of the last whorl distantly spirally ridged ; 

 aperture ovate, slightly produced at the base. 



Lea, Trans. Amer. Phil Soc. p. 26. pi. 23. f. 95. 



Hab. New Granada; Funck. 



This fine species approaches some varieties of M. cor- 

 rugata, but the longitudinal plaits are more distant from 

 each other in the region of the apex, in consequence of the 

 shell beiug formed on a less sharply attenuated plan of 

 convolution. 



Species 14. (Mus. V. d. Busch.) 



Melania imuacostata. Mel. testa subulato-pyrami- 

 duli, nigricante-olivaced, versus apicem fusco obscure 



jiammulatd, atifractibus primis conrexo-planatis, cate- 

 ris superne gradatbn excavatis, deinde plicato-costatis, 

 cost is ad angulum ubrupte luberculatis ; aperturd ob- 

 longo-ovatd, ad basin, productd et subeffusd. 



The under-bibbed Melania. Shell subulately pyra- 

 midal, blackish-olive, obscurely Hamed with brown 

 towards the apex, the first whorls convexly flattened, 

 the rest gradually excavated round the upper part, 

 then plicately ribbed, ribs abruptly tubercled at the 

 angles; aperture oblong-ovate, produced and slightly 

 efluscd at the base. 



MoussON, Land mid Siissw. Moll. Java, p. 65. pi. 10. f. 3. 

 Melania poniificalis, V. d. Busch. 



Hab. River Tjivinghin, Java. 



The shell here figured is an authentic specimen of this 

 species, from the cabinet of Dr. Von dem Busch, and, I 

 venture to think, more correctly illustrates the characters 

 described by M. Mousson than his own figure, in which 

 the ribs are not sufficiently abruptly tubercled, and the faint 

 transverse strite have too much the appearance of corded 

 ridges, such as appear in the Borneo M. circuvistriata. 

 The first few whorls of M. infracosiata are flat, and with- 

 out sculpture, and present a very characteristic though 

 obscure painting of brown flames.
