Species 192. (Mus. Cuming.) 



Melania histrionica. Mel. testa turriculatd, solidius- 

 culd, fusco-nigro el rosea alternatim fascials, aufrac- 

 tibus septent ad oclo, declwi-planatis, undigue dense 

 grano-liratis, (/ranis longitudinaliter concentrice pli- 

 catis ; apertura parva, ad basin subcanaliculaid, labro 

 superne sinuato, columella calloso-rejiexd. 



The HARLEauiN Melania. Shell turriculated, rather 

 solid, alternately banded with fuscous-black and rose, 

 whorls seven to eight, slopingly flattened, densely 

 grain-ridged throughout, the grains forming longitu- 

 dinally concentric plaits ; aperture small, slightly 

 channelled at the base, lip sinuated at the upper part, 

 columella callously reflected. 



Hah. Cape Colony. 



It may be noticed by the foregoing description that 

 there is a great deal of character in this little shell; and 

 the alternating contrast of black and delicate rose-colour- 

 ing is remarkable. 



Species 193. (Mus. Cuming.) 



Melania Branca. Mel. testa elongato-turritd, ad basin 

 clavatd, crassd, caruleo-nigrd, anfractibits novem, con- 

 vexis, longitudinaliter concentrice plicatis, spiraliter 

 liris regularibus undigue validi funiculatis, suturis 

 impressis; apertura lunari-ovatd, superne ascendente, 

 ad basin subemarginatd, columella arcuatd. 



The Branca Melania. Shell elongately turreted, club- 

 shaped at the base, thick, blue-black, whorls nine, 

 convex, longitudinally concentrically plicated, spirally 

 strongly corded throughout with regular ridges, su- 

 tures impressed ; aperture lunar-ovate, ascending at 

 the upper part, slightly notched at the base, colu- 

 mella arched. 



Hab. Rio Branca, Brazil. 



This species is of the true Vibex type, neatly closely 

 corded throughout over concentric folds. 



Species 194. (Mus. Cuming.) 



Melania Macapa. Mel. testa elongato-turritd, crassd, 

 ceeruleo igrd, anfractibus novem ad decern, convexis, 

 concent/ /is, plicis subdistantibus, spiraliter 



lira/is, liris confertis, subobtusis, suturis impressis ; 

 apertura lunari-ovatd, superne ascendente, ad basin 

 subemargiuatd, columella arcuatd. 



The Macapa Melania. Shell elongately turreted, thick, 

 blue-black, whorls nine to ten, convex, concentrically 

 plicated, folds rather distant, spirally ridged, ridges 

 close-set, rather obtuse, sutures impressed ; aperture 

 lunar-ovate, ascending at the upper part, slightly 

 notched at the base, columella arched. 



Moricand, Journ. Conch, vol. 5. p. 176. pi. 6. f. 7. 



Hab. Macapa, Guiana. 



Very similar to the preceding species, but of stouter 

 growth, with the concentric folds more distant from each 

 other. The spiral corded ridges are, moreover, more ob- 

 tuse, and even flattened in the interstices between the con- 

 centric folds. 



Species 195. (Fig. a, b, c, Mus. Cuming.) 



Melania atra. Mel. testa oblongo-turrild, crassd, nigra 

 vel nigro-olivaced, versus apicem sparsim nigro-punc- 

 tald, anfractibus novem ad decern, convexis, liris spi- 

 ralibus wndique dense" funiculatis, longitudinaliter con- 

 centrice plicatis, plicis in anfractu ultimo evanidis ; 

 apertura lunari-ovatd, supra siuuatd, infra emargi- 

 natd. 



The black Melania. Shell oblong-turreted, thick, 

 black or blackish-olive, sparingly black-dotted to- 

 wards the apex, whorls nine to ten, convex, closely 

 corded throughout with spiral ridges, longitudinally 

 concentrically plicated, plaits fading away in the last 

 whorl ; aperture lunar-ovate, sinuated above, notched 

 below.

Melanin semiplicata, Fcrussac. 

 Melania Iruucata, Lamarck. 

 Melania atra, Deshayes. 



Hab. Essequibo River, Guiana. Burmah. 



It is important to remark the geographical range of this 

 species. The specimen Fig. 195 a, b, is from Guiana, 

 and the specimen Fig. 195 c, is from Burmah, and I 

 have in vain endeavoured to trace any specific difference 

 in them.
