Nassa turrifera. (PI. I. fig. 6.) 
Testa elongata, turrita, albida, nitida, costata; spira acuminato- 
pyramidalis, turrita ; anfractus octo, supremi tres (nucleus) con- 
vexi, leves, cxeteri tabulati, lateribus planiusculis, costis tenuibus 
supra tuberculatis (in anfr. penultimo circiter 12) instructi, 
spiraliter striati et lirati, ultimus antice constrictus, infra medium 
fortius liratus, liris supra costas subtuberculatis ; apertura parva ; 
labrum extra varicosum, intus tuberculis paucis, quorum 
medianum maximum, munitum ; columella callo, tuberculis paucis 
parvis instructo, induta; canalis brevis, obliquus, recurvus. 
Longit. 10 millim., diam. 5, 
Hab. Station 162, lat. 13° 51’ 12” N., long. 80° 28’ 12” 
E., off Coromandel coast, in 145-250 fathoms. 
This species is remarkable for its elongate turreted form 
and the smallness of the aperture. The ribs are noduled at 
the upper end, almost perpendicular, and the least curved. 
The sutural line is prettily undulating. Of the three specimens 
of this interesting speties one is more elongate than the 
others ; in this the aperture is about one third the total length 
of the shell, whereas in the shorter examples it rather exceeds 
that proportion. 
Columbella (Mitrella) Pace. (PI. I. fig. 7.) 
Testa breviter fusiformis, sordide albida, levis, circa basin anfractus 
ultimi oblique sulcata; spira elongata, acuminata; anfractus 8, 
tres embryonales pellucidi, convexi, ceteri turriti, planiusculi, vel 
levissime convexi, sutura obliqua, profunda discreti, infra suturam 
striaunica marginati, ultimus infra medium constrictus, transversim 
striatus, circa caudam oblique sulcatus; apertura elongata, medio- 
criter angusta, antice canaliculata, longit. totius 3 paulo minor; 
canalis brevis, recurvus, obliquus ; columella supra arcuata, infra ~ 
obliqua, callo tenui induta, tuberculis parvis 2-3 instructa ; 
labrum ad marginem acutum, extra varice incrassatum, intus 
subtuberculatum, suturam versus leviter sinuatum. 
Longit. 12 millim., diam. 53; apertura cum canali 53 longa, in 
medio 2 lata. 
Hab. Station 162, off Coromandel coast, in 145-250 
fathoms. 
Judging from the four specimens of this species, the spire 
is liable to erosion at the apex. In the perfect example the 
_ apical whorl is almost globular, and the two following are 
also convex; these three, forming the embryonic shell, are 
pellucid and pinkish beneath the suture. 
I have named this interesting species after Mr, 8. Pace,
