5. Cypr=a tumeEscens (F. E. Edwards); Plate XIV. fig. 5 a—c. 
C. testa ovato-globosa, antice rostrata, levi: spira obtecta ; aper- 
turd elongata, angusta, antice late non profunde emarginatd, 
postice sub-canaliculata ; labro leviter arcuato, compresso, pos- 
tice producto, regulariter dentato; dentibus numerosis, plicifor- 
mibus ; labio 2 
Shell smooth, ovate, tumid, much and rather suddenly attenuated, 
so as to form, as it were, in front a perspicuous beak, broadly but 
not deeply notched at the base ; spire concealed. The aperture is 
narrow, produced posteriorly into an obscure moderately-wide canal. 
The outer lip is slightly but regularly curved, flattened on the face, 
produced at the posterior extremity, where it is suddenly bent so as 
to form the posterior canal, and presenting on the edge a row of 
rather numerous, nearly regular, pliciform teeth, which extend over 
about a half of the flattened surface of the lip, and of which those 
towards the front are the smallest. ‘The inflected posterior extremity 
is thicker than is usually the case, and the lip itself terminates in 
front in a strong oblique fold, which forms the right wall of the an- 
terior canal. The interior of the specimen figured is, unfortunately, 
so much crushed that the condition of the inner lip cannot be satis- 
factorily made out ; but the lip presents at the anterior extremity 
three oblique folds, of which the front one forms the left wall of the 
anterior canal; and this character is also found in another specimen 
(fig. 5 c), a fragment showing the condition of the outer lip and the 
anterior canal. 
The present Cyprea presents a close analogy with C. globularis 
(Edw.); but in that species the shell is more globose, and less pro- 
duced anteriorly. The aperture is more effuse, the outer lip not so 
rouch produced at the posterior extremity, and the inner lip is with- 
out the anterior folds found in this species. The nearly regular 
ovate form, and the condition of the teeth on the outer lip, of the 
shell in C. Bowerbanktw (Sow.), distinguish C. tumescens from that 
species. 
Size: In the direction of the axis, a little more than lin. and 
7 -12ths ; diameter, J in. and 1-12th.

6. CyPpRHA CANCELLATA (FI. E. Edwards); Plate XIV. fig. 6 a—e. 
C. testa oblongo-ovata, sub-cylindracea, lineis elevatis trans- 
versis striisque longitudinalibus sese decussantibus ornaté : aper- 
tura elongata, angusta, leviter arcuata, antice vix emarginata ; 
labro extis submarginato, intus regulariter dentato ; labio antice 
plicato. 
Shell oblong-ovate, attenuated towards the base, but so slightly 
as to present a somewhat cylindrical character. The surface is or- 
namented with numerous elevated transverse and longitudinal raised 
lines, decussating each other, and giving to the shell the appearance 
of being covered with net-work. The transverse lines are prominent,
