DRILLIA. 201 
D. albicincta, Ad. and Reeve (fig. 97), is a more highly colored 
adult, with the peripheral row of tubercles whitish; I find no 
other difference. 
D. reGIA, Beck. Pl. 11, fig. 80. 
Periphery with a double row of nodules, the whorls smooth 
above and granulated below it; sinus small; whitish maculated 
with chestnut. Length, 25-35 mill. Amboina, Moluccas. 
D. Stvensis, Hinds. Pl. 11, figs. 84, 94,5, 6,9; Pl. 12, fig. 11. 
Whorls numerous, convex, slightly angulated and noduled on 
the periphery, flexuously longitudinally ribbed below and cancel- 
lated by raised revolving lines; suture bordered by an obliquely 
nodulous band; yellowish or flesh-brown, sometimes narrowly 
dark-banded at the suture and base; interior yellowish. 
Length, 1 inch. 
New Guinea, Straits of Macassar, China Sea (Hinds) ; Philip- 
pines (Dunker); Japan (Dunker); Australia (Angas, Brazier, 
etc. ). 
Weinkauft’s figure of this species scarcely represents it. The 
synonyms are D. intertincta, E. A. Smith (fig. 94); D. Metcalfei, 
Angas (fig. 5); D. consimilis, E. A. Smith (fig. 11); D. Coat, 
Angas (fig. 6); D. spicata, Hinds (fig. 9). 
D. sacra, Reeve. PI. 11, fig. 89. 
Shell rather solid, somewhat gibbous towards the base; whorls 
depressed above the nodulous periphery, longitudinally granosely 
ribbed below it, with minute revolving ridges ; canal very short; 
sinus broad; yellowish white, the last whorl with a central light 
chestnut band. Length, 1 inch. Habitat unknown. 
Closely allied to the last species in form, but differs in the 
better developed ribs and in coloration. 
D. PERADMIRABILIS, HE. A. Smith. PI. 11, fig. 96. 
Yellowish white, stained with brown beneath the suture, brown- 
banded on the middle of the body-whorl, irregularly spotted and 
dotted with a lighter tint over the rest of the surface, but leaving 
a narrow, plain white zone on the periphery and another just 
below the brown band; whorls obliquely plicated, with close 
revolving lirz finely granulated, and separated by deep-cut striz. 
Length, 23 mill. Japan.
