D. INCINCTA, Watson (Azores) ; D. COMPSA, Watson (Fiji Is.) 



D. AULACOESSA, Watson (between Gape York, Australia, and 



New Guinea). 

 D. SANDWICENSIS, D. MACULOSA, D. INTEBRUPTA, Pease* 



Sandwich Isles. 

 D. GEALEI, D. TENUIOLATHRATA, D. TENELLA, Smith. 



Habitat unknown. 

 D. BUTLERI, Smith (Philippines)-, D. SUPERCOSTATA, Smith (Japan)-, 



D. SOUVERBIEI, Smith ( W. Australia) ; D. MACANDREWI, 



Smith (Persian Gulf). 



Section RAPHTTOMA, Bellardi. 



D. NUPERRIMA, Tiberi. PL 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 U. decussata, Phil., and several authors have also 

 referred it to the PI. hispidula, Jan ; but that fossil form has 

 the spiral sculpture more prominent. 



D. NEBULA, Montagu. PI. 21, figs. 20, 11 ; PL 33, fig. 56 ; PL 30, 



fig. 86. 



Longitudinally ribbed, crossed by spiral striae ; sinus broad 

 and shallow ; chestnut or horny brown, interior similarly 

 colored. Length, 12 mill. 



Norway, Mediterranean, Canary Is., W. Coast of Africa. 

 The following forms or varieties have been distinguished : 



Yar. 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. 



Yar. L^EVIQATA, Phil. (fig. 11). Elongated, with the ribs not so 

 prominent, and sometimes nearly obsolete, the revolving 

 striae 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 (PL 33, fig. 66) 

 represents a transitional form. 



Yar. COSTULATA, Risso. Ribs narrower, continuing to the base of 

 the body-whorl.
