Hab. Straits of Malacca; in seventeen fathoms, among mud. 
Cab. Belcher. 
The description is drawn up from a somewhat young specimen, 
and the mouth and last whorl have not yet attained their full deve- 
lopment. ‘The character of the shell is however very conspicuous. 
In this genus the last whorl will be found very frequently to offer 
decided features, and becomes a valuable aid in the diagnosis. 
TEREBRA PULCHRA. Ter. testd turritd, conico-subulatd, acuminatd, 
nitidd, pallidd ; anfractibus subplanulatis, longitrorsum recte plico- 
costatis, superné lined impressd cinctis, interstitiis levigatis ; an- 
fractu ultimo pallide lineato. Axis 11 lin. 
Hab. Marquesas ; in seven fathoms. 
Cab. Belcher. 
Perhaps more nearly resembling 7’. plicata than any other species, 
from which, with a little care, the description will suffice to distin- 
guish it. The specimens were collected at the Marquesas group of 
islands, which scarcely offer any particular novelty in any depart- 
ment of natural history; and the greatest exception will be found 
among Terebra, of which it has a few peculiar species, and also some 
interesting varieties of other well-known kinds. Indeed, though the 
group is by no means the metropolis of the genus, the species would 
seem to exist here under some peculiar circumstances.
