186 DRILLIA: 
below the periphery chocolate, sometimes with a white band at 
the base; interior chocolate, with an irregular white superior 
band. Length, 22 mill. 
Viti Islands, Philippines. 
The synonyms are D. vidualoides, Garrett (fig. 33), including 
the larger specimens, usually completely chocolate below the 
periphery; D. vidua, Reeve (= nigrozonata, Weink., fig. 34), 
in which there is an inferior row of very small tubercles, more 
or less apparent. D. vidua, Hinds (fig. 30), which Dr. Weinkauff 
considers a distinct species and refers to the Voy. Sulphur, 60, 
t. 6, f. 6, for description and figure, is not to be found in that 
work, and does not differ from the vidua of Reeve. Jam inclined 
to think P. Beckii of Weinkauff (Pl. 32, fig. 48) belongs here, 
whatever may be said of the very obscure species figured by 
Reeve under that name. 
D. Becxm, Reeve. Pl. 9, fig: 40. 
Shell oblong, cylindrically attenuated, sharp at the apex; six- 
angled, whorls longitudinally tuberculated at the angles; the 
entire shell olive-brown except the tubercles, which are white; 
columella and interior of the mouth brown; canal very short. 
Length, 22 mill. 
I. Luzon, Philippines. 
If Reeve’s figure of this shell is correct, Dr. Weinkauff’s iden- 
tification of it (see D. wnizonalis, above) must be erroneous. 
D. PULCHELLA, Reeve. Pl. 9, figs. 28, 29. 
Pink, with a chestnut band below the periphery, and a chestnut 
line, interrupted by the tubercles. Length, 21 mill. 
Mauritius, Philippines, Cook’s Islands. 
I think D. bilineata, Reeve (fig. 29), is identical; it appears 
to differ only in the tuberculations being less sharp and the 
color not so bright, with a brownish tinge. No locality is given 
for D. pulchella in the original description. 
D. LaTA, Hinds. PI. 9, fiz. 32; Pl. 11, fig. 87. 
Shell smooth, polished; whorls with a strongly tuberculated 
shoulder, the body-whorl with a second inferior row of small, 
sometimes obsolete tubercles; white, banded with brown, the 
band often more or less interrupted. Length, 9-17 mill. 
Sts. of Macassar, New Guinea, Viti Islands.
