The tessellated spots which characterize this species are 

 singularly constant in their form and distribution.

Marginella bullata, Kiener (not Voluta bidlata, Born). 

 llab. Brazil. 



This belongs to a type of which there are very few 

 species in the genus. 



Species 56. (Fig. a, b, Mus. Taylor.) 



Marginella cingulata. Marg. testd abbreviato-pyri- 

 formi, nitente-albd, lineis rujis conspicuis cingulata, 



spird immersd, anfractibus superne gibboso-rotundatis ; 



labro incrassato, columelld multipUcatd. 

 The belted Marginella. Shell shortly pyriform, 



shining white, encircled with conspicuous red lines, 



spire immersed, whorls gibbouslv rounded at the 



upper part ; lip thickened, columella many-plaited. 

 Voluta cingulata, Dillwyn, Cat. Shells, vol. i. p. 525. 



Marginella lineata, Lamarck. 



Marginella Bobi, De Blainville. 



Marginella cingulata, Deshayes.

The red lines, it may be observed, lose their parallelism 

 below the middle of the shell.

Marginella persicula. Marg. testd obeso-ovatd, sub- 

 pyrifurmi, fuhescente-albd, purpurascente-rnfo copiosi

 Persicula fasciata, Sch umacher. 



Hab. Mouth of the Gambia, West Africa. 



This was formerly supposed to be a variety of the pre- 

 ceding species, but it differs constantly in form as well as 

 in painting.
