 et ffriseo pulchre marmoraid etfasciaid, spird subpro- 



ductd, labro incrassato, inius denticidato, columella

Mottled and banded in a conspicuous manner with deep 

 rose-pink and grey. 



Fig. 94. (Mus. Cuming.) 



This shell, the type of !Mr. Arthur Adams' M. gem- 

 ma, proves to be a variety of the preceding species, .1/. 

 f estiva. 



Species 95. (Mus. Taylor.) 



Margi.sella albocincta. JTarg. testd conico-ovatd, 

 cinereo-grised, copiosi uigro-piinclatd, fascid alba su- 

 perne cingulatd, spird sitbexserld, atifractibiis superne 

 gibbosis, labro incrassato, columelld quadriplicatd. 



The white-belted Marginella. Shell conically ovate, 

 ash-grey, copiously dotted with black, encircled round 

 the upper part with a white band, spire rather ex- 

 serted, whorls gibbous round the upper part, lip 

 thickened, columella four-plaited.

Hab. -f 



I have no good opinion of this species. It appears to 

 be a variety of M. piperita, in which a white band is 

 formed by an accidental absence of colouring matter. 



Species 96. (Fig. a, b, Mus. Cuming.) 



Margi.sella constricta. Marg. testd subfuaiformi- 

 conicii, albidd, ob/icuri fasciatd, spird acute corded, ati-

 subjiexuoso, columella quadriplicatd. 



The constricted Marginella. Shell somewhat fu- 

 siformly conical, white, obscurely banded, spire 

 sharply conical, whorls attenuated towards the base, 

 lip thickly reflected, slightly flesuous, columella four- 

 plaited. 



Hinds, Pro. Zool. Soc. 1844, p. 74. 



Rab. ? 



Of a peculiar tapering form, but of very simple cha- 

 racter in detail. 



Species 97. (Fig. a, b, Mus. Cuming.) 



Marginella Hondurasexsis. Marg. testdovatd, tenui, 

 infiatd, fiavescente-corned, nitente, livido-fusco trifas- 

 ciatd, spird subacute conicd, aperturd subpatuld, la- 

 bro vix incrassato, columelld quadriplicatd. 



The Honduras Marginella. Shell ovate, thin, inflated, 

 yellowish horn-colour, shining, three-banded with 

 livid-brown, spire rather sharply conical, aperture 

 rather wide open, lip scarcely thickened, columella 

 four-plaited. 



llab. Honduras. 



Distinguished by its light inflated growth and peculiar 

 tone of colour. 



Species 98. (Mus. Cuming.) 



Marginella vexillum. Marg. testd conico-ovatd, 

 albidd, violaceo-fusco fasciatd et maculatd, spird sub-

The flag Marginella. Shell conically ovate, whitish, 

 banded and blotched with violet-brown, spire rather 

 prominent, whorls tumidly gibbous round the upper 

 part, attenuated at the lower, lip tumidly thickened, 

 dotted throughout, denticulated within, columella 

 four-plaited. 



Redfield, MS. in ^lus. Cuming. 



llab. Cape Palmas, Liberia. 



This appears to be a very cliaracteristic species, but T 

 have only a very indifferent specimen to judge by.
