MELANIA.— Plate IV. 



Species 19. (Mus. V. d. Busch.) 



Melania pulchra. Mel. testa elongato-turritd, nigra, 

 anfractlbus novem ad decern, rotundatis, liris distanti- 

 bus clngulatis, quarum duabus centralibus tuberculatis ; 

 aperturd ovatd. 



The beautiful Melania. Shell elongately turreted, 

 black, whorls nine to ten, rounded, encircled with 

 distant ridges, of which the two middle ones are tu- 

 berculated ; aperture ovate.

Hab. ? 



I adopt this species with reluctance. It appears to me 

 to be an unusually fine example of the variety of M. aspe- 

 rata, figured at Plate I. Pig. 2 a and 2 b. If M. pulchra 

 be allowed to stand, these two shells may be referred to it 



Species 20. (Mus. Cuming.) 



Melania obeliscus. Met. testa pyramidal}, solldd, ni- 

 gra, anfractlbus octo ad novem, primis planls, lavibus, 

 cateris excavato-declivibus, delude conspicue tubercu- 

 lato-angulatis, anfractiis ultimi parte inferiori spira- 

 liter liratd ; aperturd oblongo-ovatd, subproductd. 



The obelisk Melania. Shell pyramidal, solid, black, 



whorls eight to nine, the first flat and smooth, the 

 rest excavately sloping, then conspicuously tubercu- 

 lately angled, lower portion of the last whorl spirally 

 ridged beneath ; aperture oblong-ovate, slightly pro- 

 duced. 

 Hab. Honduras ; Dyson. 



A fine, solid species, partaking of the typical characte- 

 ristics of M. polygonata. It is remarkable for the com- 

 pressed tubercular prominence of the periphery of the last 

 and penultimate whorls. 



Species 21. (Mus. Cuming.) 



Melania eustica. Mel. oblongo-subulatd, fusco-nigrd, 

 anfractibus subangustis, lavibus, supeme sublate super- 

 Jicialiter excavatis ; aperturd parviusculd, margine 

 columellarl calloso-planato. 



The kustic Melania. Shell oblong-subulate, fuscous- 

 black, whorls rather narrow, smooth, rather broadly 

 superficially excavated at the upper part ; aperture 

 rather small, columellar margin callously flattened. 



Mousson, MS. Mus. Cuming. 



Eab. ? 



The whorls of this species are smooth, and rather nar- 

 rowly drawn out, and the sutural excavation is propor- 

 tionably broader, and superficial.
