Section Rapuitoma, Bellardi. 
D. NUPERRIMA, Tiberi. PI. 22, fig. 49. 
Rather thin, with about twelve distant, small longitudinal 
riblets, crossed by distant raised lines. Length, 12 mill. 
Mediterranean Sea, rare. 
It is DV. decussata, Phil., and several authors have also 
referred it to the Pl. hispidula, Jan; but that fossil form has 
the spiral sculpture more prominent. 
D. nesButa, Montagu. PI. 21, figs. 20,11; Pl. 33, fig. 56; Pl. 30, 
fig. 86. 
Longitudinally ribbed, crossed by spiral strize ; sinus broad 
and shallow; chestnut or horny brown, interior similarly 
colored. Length, 12 mill. 
Norway, Mediterranean, Canary Is., W. Coust of Africa. 
The following forms or varieties have been distinguished : 
Var. GINNANNIA, Risso. Ribs larger and stronger, yet the 
revolving sculpture is well marked. Mostly Mediterranean. 
This is not the P. Ginnannia of Reeve’s Iconica. 
Var. L&vIGATA, Phil. (fig. 11). Elongated, with the ribs not so 
prominent, and sometimes nearly obsolete, the revolving 
strize faint. Reeve’s figure, which I have copied, is inac- 
curate, as it ought to show some traces of longitudinal ribs ; 
it is magnified three times. Jeffrey’s figure (PI. 33, fig. 66) 
represents a transitional form. 
Var. costuLATA, Risso. Ribs narrower, continuing to the base of 
the body-whorl. *
