DRILLIA. 181 
This is possibly only a dark-colored, strongly sculptured D. 
gibbosa. It is P. turricula, Sowb., not Montagu, and P. cor- 
rugata, Sowb., not Kiener. 
D. maurA, Sowerby. PI. 10, fig. 70; Pl. 32, fig 43. 
Shell dark chocolate-color, with oblique longitudinal ribs ; 
‘ nodulous at the crossing of raised revolving lines. 
L. 48, diam. 13 mill. 
West Columbia (Cuming). 
D duplicata, Weinkauff (not Sowerby) (Pl. 32, fig. 43), is a 
synonym. 
D. miniraris, Hinds. PI. 10, fig. 74. 
Acuminately turreted, yellowish white, sometimes stained with 
brown; whorls decussated with nodulous longitudinal ridges, 
and spiral strie; upper part of the whorls concave, edged with 
a slightly nodulous keel. L. 43, diam. 12 mill. 
Veragua, W. Coast of America. 
Iam not acquainted with this species, but think it probable 
that it is only a light-colored variety of the preceding one. 
PD. LANCEOLATA, Reeve. Pl. 10, fig. 65; Pl. 32, fig. 44. 
Shell orange-brown, the tubercles lighter-colored; spiral 
strie stronger towards the base of the body-whorl. 
Length, 53 mill. 
Japan. 
Reeve’s figure being from a poor and broken specimen, I add 
a much finer one from von Martens (fig. 44). It may be distin- 
guished from its allies mainly by the narrower form. 
D. inteRRUPTA, Lamarck. PI. 10, figs. 68, 76. 
Sharply turreted, longitudinally ribbed and spirally striated ; 
yellowish brown, the ribs reddish brown. Length, 30 mill.

Color brown of various tints, often deep brown, with one or 
two spiral bands of yellowish brown, and with streaks of light 
brown, or the ribs maybe pale yellowish brown, aperture brown
