396 GASTEROPODA OF THE INFERIOR OOLITE. 
Section 6.—GRANULATR. 
Shells trochiform, mostly inclined to be depressed, generally rather small, 
more or less umbilicate. Whorls sloping, flat or subangular ; body-whorl relatively 
large, and usually with a very convex base. Ornaments for the most part deeply 
incised, so that cross-hatching produces a granular appearance. Sinus-band 
anterior, narrow and prominent, frequently constituting a keel.

In the above, Pl. granulata, plicopunctata, and Palemon constitute the 
granulata-group proper, which, be it remembered, was united with the mutabilis- 
group by Deslongchamps toform one section. Hence, according to the classifica- 
tion of that author, the Conic and the Granulate, as defined above, should for 
the most part be united. This constitutes the principal difference between the 
arrangement now adopted and the divisions in the ‘ Mémoire sur les Pleuroto- 
maires.’

Bibliography, 5:c.—Sowerby’s figure, from a Dundry specimen, is somewhat 
indifferent, but there is no doubt as to the identification, this being one of the three 
species of Inferior Oolite Plewrotomarix, where the figured specimen is preserved 
in the “Sowerby Type Collection” at the British Museum. D’Orbigny’s
