Shell ovoid, depressed ; surface smooth ; spire very slightly ele- 
vated near the apex, which is rounded; whorls 3, closely wound, 
the last expanding much ; the line of suture is not a regular spiral, 
from the last whorl closing in on the second and narrowing its 
breadth in front very considerably. 
Size: major diam. 13, minor diam. 9°4 mm. 
Animal (Plate XLII. figs. 1, 2, 3), in spirit-specimen, 22:5 mm. 
in length, with a truncate glandular extremity of foot; the pedal 
line distinct, with some black spottings, the pedal margin having a few 
at the posterior end; the dorsal portion above is also darkly mottled. 
The mantle-lobes are finely and distinctly papillate and closely 
mottled with black. The right shell-lobe is broad, extending towards 
the shell ; it narrows posteriorly, and is continuous round to the left 
shell-lobe. The right dorsal lobe is small, but the left very ample 
and continuous. The ridge of the foot behind, just beneath the 
posterior margin of the shell, forks into two ridges (fig. 3), and this 
portion of the shell rests in the long triangular depression between 
them, a formation of the body similar to that of Girasia. 
Odontophore (figs. 6, 6a, 6b). As in Macrochlamys ; the laterals 
bicuspid, the inner cusp much longer than the outer, which is small 
and on the last scarcely developed. The teeth are arranged
