95. Marginella ANGUSTATA {\A. Ixxvu. L IGd, 170.), nof/is. 

 Zool. Proc, 1846. Voluta biillata^ Gmel. and Kiener. 



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

 ruptis fasciatim cincta ; spira celata, -, apertura elongata, ad apiceiu 

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

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

 extus rubro, late et tenuiter expanse. 



The true M. hnllata 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 liidden by the outer lip, which is 

 thiidy and broadly reflected. I'rom the East Indies. 



96. Marginella miliauia (pl.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 intiis crenulato, postice emarginato, exti^is 

 paululum incrassato. 



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

 band, spire small, encircled with a reddish line ; a])erture length- 

 ened, marginated at both extremities; columella thickened, Avith 

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

 the outisde. 



From Senegal. 



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

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

 Lam. Anim. s. vert. vol. vii. inclusa. 



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

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

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

 ad marginem quinqucplicato, 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.
