Obs. Fifteen distinct species of AnomiU, collected in Derbyshire, still remain in our hands 
unnoticed Most of these we have rnet with since the drawings and descriptions for the present 
volume were Hnished. Five belong to the Perfomli, Fam.f.f., but only one there is any danger 
of mistaking for Sacculus— It may be distinguished by the following characters. 
Conch. Anomites attenuatus. 
C, Anomites longitudinaliter ovatus Isevis compressus, margine acuto integerrimo. 
The Anomite are more numerous in this county than any other tribe of shells— and are, with 
the exception of two species, wholly confined to our limestone strata. The species alluded to are 
the C. A. Gryphus & Pecten—(IIelm. Gryphites Helm. Anomites. V. Pecten. Linn. Syst. Nat.) 
the former has been found in marl, in modern tracts, near Derby, the latter, in the shale of our 
coal-mines.
