4 Mr. E. A. Smith on Mollusca from the 
Pleurotoma presignts. (PI. I. fig. 4.) 
Testa fusiformis, turrita, alba, epidermide tenui flavescente induta ; 
anfractus 11-12?, regulariter lente crescentes, superne ad suturam 
fortiter carinati, in medio prominentes, serie nodularum sub- 
acutarum instructi, infra nodulas linea filiformi (in anfr. superi- 
oribus obsoleta), et supra nodulas lineis duabus gracillimis cincti, 
ultimus infra medium angustatus, brevirostratus, infra nodulas 
circiter quatuor aliisque tenuioribus circa caudam ornatus ; 
apertura alba, cum canali longit. totius 3 equans ; labrum tenue, 
ad nodulas mediocriter profunde et latissime sinuatum, infra 
sinum prominens, arcuate productum; columella supra medium 
leviter incurvata, inferne paulo obliqua; canalis brevis, sub- 
recurvus. 
Longit. 42 millim., diam. 15; apertura cum canali 16 longa, in 
medio 54 lata. 
Hab. Off Colombo, Ceylon, in 675 fathoms. 
The prominent row of tubercles around the middle of the 
whorls, the keel beneath the suture, and the broad sinus in 
the labrum are the principal features of this species. The 
apex of the spire being broken away makes it impossible to 
state with certainty the exact number of whorls, but they 
would probably amount to eleven or twelve. The entire 
surface exhibits fine flexuous lines of growth. 
Drillia fugata. (PI. I. figs. 5, 5 a.) 
Testa elongata, turrita, alba, epidermide tenui flavo-olivacea induta, 
spiralter striata, oblique costulata; spira elongata, acuminata ; 
anfractus decem, conyvexiusculi, superne excavati, ad suturam 
undulate subcarinati, infra excavationem costis obliquis (in anfr. 
ultimo J1-12 inferne attenuatis et evanescentibus) instructi, 
ultimus antice paulo attenuatus ; apertura angusta, alba, longit. 
totius + paulo minor; labrum superne ad excavatione haud pro- 
funde sinuatum; columella rectiuseula, callo tenui albo induta; 
canalis mediocriter latus, brevis, leviter recurvus. 
Longit. 45 millim., diam. 14; apertura 20 longa, 6 lata. 
Var. Testa striis latioribus transversim sculpta, interstitiis liri- 
formibus supra costas continuis (fig. 5 a). 
Hab. Station 172, off Trincomalee, in 200-350 fathoms. 
The greater breadth of the spiral strie and the more con- 
spicuous intervening ridges give the variety a somewhat 
distinct appearance from the type. The character of the 
coste, the depression above them, the thickened wavy margin- 
ation beneath the suture, and the epidermis are, however, 
similar.
