490 '  GASTEROPODA OF THE INFERIOR OOLITE. 
450. Cirrus, species or variety. Plate XLIV, fig. 12. 
The interest of this specimen consists in the fact that it is the only one of the 
genus known to me from the Lincolnshire Limestone (Stoke Lodge). It may 
possibly be a micromorph of Cirrus Leachi. 
451. Onustus prieus, Lycett, 1850. Not figured.

The following is Lycett’s diagnosis. ‘‘ Very elevated; whorls few, concave, 
with longitudinal elevations united at the base, and overwrapping the upper 
portion of the succeeding whorl, base discoidal.’” Further on he adds that this 
will probably be erected into a new genus. 
There is a single specimen in the Brodie Collection, the apical whorls alone 
being preserved. It is clearly a species of Onustus, related to O. acwminatus, 
Hudl. There are two much larger specimens, also from the Cotteswolds, which 
have been in the Jermyn Street Museum for some years (see p. 328, supra). 
These may be referred to Onustus pileus, Lycett. 
452. DenpHinuta or Marearira, species. Plate XLIV, figs. 3a, 3b. 
This form has considerable resemblance to Delphinula (Turbo) Santonis, Hudl., 
differing principally in details of ornamentation. At the same time I would 
scarcely refer to it as absolutely the same species. 
A single specimen, said to come from Cold Comfort in the Cheltenham district. 
453, DELPHINULA QUATERNO-CINGILLATA, Lycett, 1850. Not figured.

Club, vol. i, p. 77. 
This is a doubtful species, since the two specimens thus marked in the Brodie 
Collection differ in more than one respect from the diagnosis, which is as follows :— 
** Subglobose, spire of several whorls, angulated; longitudinal coste large, elevated, 
rather angular, impressed by numerous transverse (spiral) lines; umbilicus 
costated ; aperture orbicular.”
