GASTEROPODA. 47 
Shell subglobose, spire elevated, whorls (4—5) angulated, the angles nodulated, the 
nodules being small and numerous; the whorls are flattened above and beneath the angle ; 
the last whorl is globose, and has two encircling nodulous carine, with a depression between 
them ; the aperture is large and elliptical; the base rounded and wide ; the pillar lip with 
an open umbilicus. 
This may be regarded as an aberrant form of Zwuspira, in which the carina becomes 
nodulous ; the nodules, however, are not prominent nor large, those of the second carma 
being smaller, more numerous, and rather indistinct. ‘There is also a slight sulcus between 
the carinze which are comected together by obscure elevations, but these merely appear as 
slight plications. The general form being globose, and the carina broken into nodules, 
renders its aspect less angular than is usual in the genus. Length 21 lines, breadth

EvsPira suBCANALIcULATA. Plate VI, fig. 13. 
EB. Testa oblonga ; spira sub-exserta ; anfractibus (4) angulosis, marginibus subdepressis, 
superne tabulatis, inferné subconvexis; anfractu ultimo obliquo; aperturd subtrigond; 
obliqua, basi angustata ; labro interno calloso umbilicum obtigente. 
Shell oblong; spire but little elevated; whorls (4) angulated, their margins rather 
depressed, flattened above the angle, and rather convex beneath; the last whorl oblique ; 
aperture subtrigonal, the last whorl oblique, the base narrow; the imer lip thickened, and 
covering an umbilicus. 
Unfortunately we possess only one specimen of this little shell, which was obtained in 
the planking; it may possibly be a young variety of £. canaliculata, in which the upper 
portions of the whorls may become channelled with advance of growth, and the general 
figure more globose; the appearance of the inner lip and umbilicus, however, are certainly 
different ; and we, therefore, prefer to keep this as a distinct species. Length 8 lines, 
breadth 7 lines.
