Species 235. (Mus. Morelet.) 



Melania cinerea. Mel. conico-turriculatd, crassiusculd, 

 molaceo-cinered, infra suluras rvfo el plumbeo fasciatd, 

 suturis albidis, epidermide tenui olivaced indutd, spird 

 acuminata, anfractibus novem ad decent, couvexis, lon- 

 gitudinaliter malleatis, transverse dense minutissime 

 undato-striatis; aperturd rotundato-pyriformi, colu-

The ash-coloured Melania. Shell conically turricu- 

 lated, rather thick, violet-ash beneath the sutures, 

 banded with red and lead-colour, sutures white, co- 

 vered with a thin olive epidermis, spire acuminated, 

 whorls nine to ten, convex, longitudinally malleated, 

 transversely densely very minutely wave-striated ; aper- 

 ture rotutidately pear-shaped, columella callous at the 

 upper part.

Hah. Environs of Cohan, Vera-Paz ; Morelet. 



An interesting species of the Pachyckilus section of the 

 genus, allied to F. Oumingii, Lea, described at Plate XXI. 

 Sp. 149. This, and all the species of Plate XXXV. ex- 

 cepting Sp. 236, are described and figured from the ori- 

 ginal types kindly sent to me by M. Morelet. 



Species 236. (Mus. Cuming.) 



Melania Gassiesii. Mel. testa subelongato-turritd, 

 fulvo-olivaced , anfractibus subungualis, superne declivi- 

 concavis, delude plano-convexis, lisvigatis, sub lente rni- 

 nutissime undato-striatis ; aperturd parviusculd, ovatd, 

 ad basin, effuso-prod uctd, columella tenue contortd. 



Gassies' Melania. Shell rather elongately turreted, 

 fulvous-olive, whorls rather narrow, slopingly concave 

 round the upper part, then flatly convex, smooth, 

 very minutely wave-striated beneath the lens ; aper- 

 ture rather small, ovate, eft'usely produced at the 

 base, columella thinly contorted. 



Hab. Central America. 



This shell, collected by M. Salle, is certainly distinct 

 from the few allied species already figured. 



Species 237. (Mus. Morelet.) 



Melania Commeksoni. Mel. testa gracili-turriculatd, 

 olivaceo-viridi, subpellucidd, anfractibus novem ad de- 



cern, aid pluribns, rotundatis, ad suluras declivi-im- 

 pressis, spiraliter irregulariter tiru/is, longitudinalUer 

 tenuiplicatis et dense rninutissime crispato-striatis ; 

 aperturd ovatd, parviusculd, columella ad basin intorto- 

 effusd. 



Commerson's Melania. Shell slenderly turriculated, 

 olive-green, somewhat transparent, whorls nine to 

 ten, or more, rounded, slopingly impressed at the su- 

 tures, spirally irregularly ridged, longitudinally finely 

 plicated, and densely very minutely crisp-striated; 

 aperture ovate, rather small, columella twistedly ef- 

 fused at the base. 



Morelet, MS. in Mus. Morelet. 



Hab. Madagascar. 



In general resemblance this shell approaches M. Neto- 

 comMi, coarctata, and iudejiuita, but they all differ from 

 one another in detail of sculpture. 



Species 238. (Mus. Morelet.) 



Melania immanis. Mel. testa conico-pyramidali, solidd, 

 fulvo-olivaced, anfractibus novem ad decent, deelivibus, 

 oblique coucentrice coslatis, liris subdistantibus undique 

 spiraliter funiculatis, aufractu medio gibboso, superne 

 concavo, eostis gradatim evanidis, sed liris lubercula- 

 tis ; aperturd ovatd, ad basin subeff'uso-productd. 



The wonderful Melania. Shell conically pyramidal, 

 solid, fulvous-olive, whorls nine to ten, sloping, ob- 

 liquely concentrically ribbed, spirally corded through- 

 out with rather distant ridges, last whorl gibbous in 

 the middle, concave round the upper part, the ribs 

 gradually disappearing but tubercled by the ridges ; 

 aperture ovate, somewhat efl'usely produced at the 

 base. 



Morelet, Test. Nov. Ainer. Cent, part ii. p. 22. n. 139. 



Hab. Central America ; Morelet. 



In this truly fine species the whorls are ribbed longitu- 

 tinally and strongly corded tranversely, the cords passing 

 over the ribs. The last whorl increases materially in con- 

 vexity, and the ribs partially disappear, but the transverse 

 cords are stronger, and on crossing the fading ribs they 

 rise into tubercles.
