464 GASTEROPODA OF THE INFERIOR OOLITE. 
Bibliography, §c.—Briefly described by Lycett, but not figured. Notaccepted by 
Morris, nor enumerated by Lycett in the ‘ Cotteswold Hills’ amongst the fossils of 
the Fimbria-stage. In the absence of further evidence P. retifera was included by 
Hudleston and Wilson in the list of ‘ species not accepted.” Quite lately (1895) 
Mr. Brodie’s collection of fossils from the Leckhampton freestones has been 
acquired for the Jermyn Street Museum. There are two specimens purporting 
to be Patella retifera, besides specimens of Fissurella Brodiei, which latter is a 
closely allied, if not identical form, ina somewhat different matrix. The labels 
are not in Lycett’s handwriting.

*Ovate, costated, and cancellated ; costz numerous and unequal, crossed by 
numerous encircling lines; apex moderately elevated, posterior, but inclined 
forwards.” 
The so-called Fissurella Brodiet exhibits the same characters, but is a shghtly 
narrower shell. 
Relations and Distribution—Both radial and concentric ornaments of this 
extremely pretty little shell are very sharp, and this serves to distinguish it from 
Patella (Guerangeria) clypeola, Deslongchamps, a Bathonian species, where the 
radial ornamentation only is in evidence. There is something peculiar in the 
character of the apex, which seems to indicate that it may not be a Patella in a 
strict sense, though none of the specimens could be placed under Fissurella. 
There are about half a dozen specimens in the Brodie Collection from the 
Leckhampton freestones, which contain a shallow-water fauna.
