PATELLA. AGL 
In specimens from the Great Oolite the figure is stated to be a more lengthened 
oval, whilst the apex is somewhat more elevated. 
Relations and Distribution.—Less orbicular and less conical than P. nitida ; 
moreover, in this species, the convex side (not sufficiently convex in fig. 4a) is 
the shorter. My best specimens are from the base of the Lower Freestones, 
Leckhampton, where P. inornata is not uncommon. It also occurs in the North- 
ampton Sand at Duston, and in the Lincolnshire Limestone at Stoke Lodge.

Morris and Lycett (‘Great Ool. Moll.,’ pt. i, p. 88) refer certain shells from 
the Cotteswolds to Miinster’s species. heir figures are not satisfactory ; and, as 
P. cingulata is an Upper Jurassic form, Cossmann (‘ Etage Bathonien,’ p. 354) 
suggests that the Great Oolite forms may represent a different species. 
There are two specimens in the Jermyn Street Museum from the Inferior 
Oolite of Rollwright Heath, in Oxfordshire, which is very high in the series. In 
their depressed outline these specimens more nearly resemble the figures of 
Goldfuss than those of Morris and Lycett. The principal resemblance, however, 
is in the striated growth-lines (fig. 5c), thus producing a marked concentric 
ornamentation.

Bibliography, §c.—There are two specimens in the Jermyn Street Museum, 
most probably from the Inferior Oolite, Leckhampton. On these Lycett based his 
identification.
