95. Marginella angustata (pl.lxxvii. f. 169, 170.), nobis. 

 Zool. Proa, 1846. Voluta bullata, Gmel. and Kie?ier. 



M. elongato-ovali, pallide rubra vel Crimea, lineis rubris inter- 

 ruptis fasciatim cincta ; spira. celata ; apertura elongata, ad apicem 

 extensa; columella postice et antice callosa, plicis tribus, quarum 

 antica unica magna, pene duplicate ; labio externo crasso, albo, 

 extus rubro, late et tenuiter expanse 



The true M. bullata is figured so unquestionably in Born and 

 Chemnitz, that it is a matter of surprise that M. Kiener should 

 have followed Gmelin in applying the name to this species. M. 

 angustata is narrow, with bands of colour crossing each other in 

 the two directions, and the spire hidden by the outer lip, which is 

 thinly and broadly reflected. From the East Indies. 



96. Marginella miliaria (pi. lxxviii. f. 227 to 230.), Linn. 

 Syst. Nat. vol. xii. p. 184. M. oryza, Lam., inclusa. 



M. parva, pyriformi, ventricosa, alba vel pallide fulva, fascia 

 lata, fusca, in medio cincta, postice marginata, spira parva, rubro 

 cincta; apertura elongata, antice emarginata; columella quinque- 

 plicata, labio externo iiitus crenulato, postice emarginato, extus 

 paululum incrassato. 



Small, pyriform, white or pale-brown, with a broad brown 

 band, spire small, encircled with a reddish line ; aperture length- 

 ened, marginated at both extremities; columella thickened, with 

 about five folds ; outer lip crenulated within, slightly thickened on 

 the outisde. 



From Senegal. 



97. Marginella Persicula (pi. lxxviii. f. 189, 190, 191.), 

 Voluta Persiula, Linn. Syst. Nat. ed. 12. p. 1189. M. avellana, 

 Lam. Anirn. s. vert. vol. vii. inclusa. 



M. breviter sub-ovali, pallide fulva, punctis rubris ornata ; spira 

 celata, apertura spiram superante, postice et antice valide emar- 

 ginata, columella callosa, alba, prope spiram varice valido, antice 

 ad marginem quinqueplicato, plica magna obliqua terminali ; labio 

 externo postice arcuato, intus crenato. 



This species and M. lineata differ oidy in the latter having lines, 

 and the former, spots. While retaining this as, at least, a recog- 

 nizable distinction, we cannot establish any distinction between 

 the variety of M. persicula (f. 189.) with large spots, M. avellana, 

 Lam., and the variety having the spots much smaller. 



From the river Gambia.
