300 Mr. E. A. Smith on 
specimens there is a slight tooth-like projection near the base 
of the columella. 
In general form this species is rather like P. producta, 
Pease, from the Sandwich Islands ; but the sculpture is diffe- 
rent. In the former the cancellation is much more open, and 
the liree are scarcely nodulous at the points of intersection 
with the longitudinal ribs, whereas in the latter the ribs are 
very close together. 
Pleurotoma (Defrancia ?) subgranosa. 
Testa ovata, alba, infra suturas zona flavo-fusca, et infra medium 
anfr. ultimi altera, ornata; anfractus 63, primi 23 convexi, ob- 
lique tenuiter costati, cteri convexuisculi, sutura canaliculata 
sejuncti, costis subcrassis 12 (in anfr. ultimo basi continuis) et 
liris spiralibus (in anfr. tertio quartoque 3, in penultimo 4, in 
ultimo 12) supra costas subgranosis cancellati ; apertura angusta, 
longit. totius ;5- adequans; columella medio incrassata ; labrum 
incrassatum, intus denticulis 5 armatum; sinus subamentiformis, 
paululum infra suturam situs; canalis angustus, brevis, basi 
truncatus. 
Long. 53 mill., diam. 2}. 
Hab. ? A variety from Singapore. Coll. Cuming. 
The brownish band below the suture includes the two upper 
lirations; that around the body-whorl colours the sixth and 
seventh (reckoning from the suture). The single specimen 
from Singapore is undoubtedly this species, but has a slightly 
distorted look and is of larger dimensions, being 7 millim. 
long and 3 broad. 
Pleurotoma (Defrancia?) associata. 
Testa fusiformi-ovata, turrita, rubro-fusca, circa medium anfr. ulti- 
mi zona angusta flava cincta; anfract. 63, primus 13 levis, politus, 
ceeteri convexiusculi, supra oblique tabulati, costis 12 (in anfr. 
ultimo basim vix attingentibus) et liris spiralibus 4 supra costas 
nodulosis instructi; anfr. ultimus liris circiter 15, inferioribus 6, 
vix nodulosis, succinctus; apertura longit. totius ad 3 equans ; 
labrum incrassatum, intus denticulis 5-6 munitum; columella 
juxta suturam callosa ; canalis angustus, brevis, truncatus. 
Long. 7 mill., diam. 23. 
Hab. ? 
P. zonulata, Angas, appears to be the nearest ally of this 
species. 
Pleurotoma (Daphnella) Souverbiet. 
Testa elongato-ovata, parum nitida, alba, lineis spiralibus paucis 
interruptis lacteis ornata; anfract. 9?, apicalibus 3 fractis su- 
premi reliqui 3-4 longitudinaliter oblique costati, spiraliterque
