520 A. E. Yerrill— Catalogue of Marine J lollusca. 
It is easily recognized by its conical spire, and its flattened base, 
covered with revolving grooves and ridges. The revolving cinguli 
on the spire are stronger than those on the base, and unequal. 
Torellia fimbriata Verrill and Smith, sp. nov. 
Plate LYII. figcees 27, 27a. 
Shell thin, fragile, translucent, broader than high, with a short, 
depressed spire, the apex small and a little prominent, the last whorl 
large and ventricose, with spiral carinae bearing divergent epidermal 
hairs. 
Whorls five, very convex, rapidly enlarging; suture deep, slightly 
channeled; nuclear whorls smooth and glossy, regularly spiral, the 
first whorl minute. Sculpture, several raised, angular, spiral carinae, 
separated by unequal intervals, on which are finer spiral lines; and 
numerous, very evident, thin, raised flexuous lines of growth, which 
cross both the intervals and carinae, rendering the latter finely nodu- 
lous. On the last whorl there are about ten carinae ; each of which 
usually supports a spiral row of long epidermal hairs ; the uppermost 
of these is just below the suture, and its epidermal processes are long 
and appressed against the preceding whorl ; the next is separated by 
a wide space, while those on the convex part of the whorl are nearer 
together; the last defines the border of the umbilicus, which is deep, 
but not broad. Aperture large, roundish, the lip continuous in adult 
shells ; in the umbiblical region the lip is somewhat reflected, so as to 
partially conceal the umbilicus ; within the lip the columella has a 
very obtuse lobe, projecting inward. 
Epidermis thick, pale yellowish, or greenish yellow, more or less 
lamellose along the lines of growth, and usually rising into long and 
large divergent hair-like processes along the spiral carinae. Shell yel- 
lowish white. 
The median teeth of the radula (fig. 27'/), have broad, truncated 
bases, with the lateral angles a little prominent and rounded ; the 
free end is broad-triangular, with slightly concave lateral lines, 
bearing small sharp denticles, or sometimes merely crenulated ; the 
median denticle is acute and prominent. The large lateral teeth 
have broad bases, of which the outer edge is oblique, with the 
anterior corner prominent and rounded; the tip is strongly obliquely 
curved, and very sharp. The outer lateral teeth are strongly hooked 
and very acute.
