252 MR. G. B. SOWERBY ON NEW SHELLS. [Apr. 28, 
RAPA BULBIFORMIS. 
R. subglobosa, albido-subviridi, infra spiraliter imbricato-lirata ; 
spira producta ; anfractibus 6, rotundis ; apertura pyriformi, an- 
gustiuscula ; labio infra crenulato. 
Hab. Tongataboo, Friendly Islands. 
This shell was found by Mr. Brazier in a large hole in a coral-reef, 
on a piece of sponge, in five-feet water. It has a much more pro- 
duced spire than the known species, with rounded whorls. 
Fusus RUBRO-LINEATUS. 
F. testa breviuscula, pallide rubescente, castaneo bifasciata, distanter 
spiraliter rubro lineata, tenuiter striata ; spira breviuscula; an- 
fractibus septem, costis longitudinalibus subdistantibus rotundis 
spiraliter liratis ornatis, superne fascia castanea lata cinctis; aper- 
tura subovata, in canalem subelongatum terminante. 
Hab. Agulhas Bank, S. Africa. 
Mus. Taylor. 
TEREBRA TENUISCULPTA. 
T. testa angustissima, elongata, fusca, saturatiore flammulata, vel 
albida castaneo pallide flammulata; anfractibus compressis, supra 
prope suturam liris spiralibus inequalibus prominentibus granoso- 
moniliformibus cinctis, infra cancellatis, ultimo infra angulum tenui- 
ter sculptis. 
Hab. China Seas.

Esurna PERFORATA. (Plate XXI. fig. 2.) 
E. testa rotundato-pyramidata, maculis magnis fulvidis undatis, medio 
anfractuum truncatis, infra medium in series duas dispositis, 
subrotundis, brevibus picta; spira breviuscula, apice purpureo ; 
anfractibus breviusculis, rotundis ; canali suturali lato, profunde, 
excavato ; umbilico latissimo, usque ad apicem spiraliter excavato, 
medio spiraliter calloso ; apertura parva ; labio columellari levi- 
ter arcuato. 
The deep, wide canal and short rounded whorls, an arrangement 
of spots differing from all the other species’, and a spiral groove at 
the lower part of the whorl, resembling only that in ZL. formose, 
Sowb., render this a very remarkable shell. It has a very wide and 
perforating umbilicus, in which it is only nearly approached by Z. 
spirata, Linn., and a spiral umbilical callus resembling that in H. 
eanaliculata. 
TURRITELLA EXCAVATA. (Plate XXI. fig. 3.) 
T. testa attenuata, acuminata, tenuiuscula, sublevigata, albida, medio 
anfractuum castaneo, spiraliter fasciata ; anfractibus subelongatis, 
medio excavatis, supra prope suturam angustatis, tumidis, infra 
latis, inflatis, rotundatis ; apertura subpyriformi, labio profundis- 
sime et late supra medium emarginata. 
Hab, Agulhas Bank.
