DRILL! A, -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. SINENSIS, Hinds. PI. 11, figs. 84, 94, 5, 6, 9 ; PI. 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 (D unker) ; Japan (Bunker) ; Australia (Angas, Brazier, 

 etc.). 



Weinkauff 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. Coxi, 

 Angas (fig. 6) ; D. spicata, Hinds (fig. 9). 



D. SAORA, 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, E. 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 lirae finely granulated, and separated by deep-cut striae. 



Length, 23 mill. Japan.
