DRILLIA. Lor 
The following unfigured species are referred by the describers 
to this section of Drillia; they are all unknown to me, except 
through the preliminary descriptions. 
D. MARMARINA, Watson. Off Pernambuco. 
Obtained by the Challenger Expedition. Said to be allied to 
D. sacra, Reeve—which does not belong to this section of the 
genus. : 
D. ALBOANGULATA, E. A. Smith. Habitat unknown. 
D. spinosa, E. A. Smith. (Allied to D. lata, Hinds.) 
Habitat unknown. 
D. inTERPUNCTA, E. A. Smith. St. Thomas, W. I. 
The description applies pretty well to some individuals of D. 
coccinata, Reeve.

D. nupis, Sowerby. PI. 14, figs. 85, 90. 
Shoulder of the whorls prominently tuberculated, with smaller 
tubercles below it where the flexuous longitudinal ribs are 
crossed by coarse revolving lines; above the shoulder the whorls 
are contracted, and tuberculated at the sutures; chocolate-brown, 
usually broadly white-banded above the periphery, or the tubercles 
only white, with sometimes a narrow white band near the base. 
Length, 25-35 mili. 
Galapagos Islands (Sowb.); Panama to Mazatlan. 
D. excentrica, Sowb. (fig. 90), is founded on an abnormal 
specimen, the last whorls somewhat displaced. 
D. picirauis, Reeve. Pl. 13, fig. 75. 
Shell dark chocolate, covered by rows of lighter-colored granu- 
lations, caused by the decussation of small flexuous rather 
numerous longitudinal ribs and elevated revolving lines; aperture 
light chocolate. Length, 20 mill. Philippines, Mauritius.
