1862. Terebratula (Waldheimia) numismalis; Deslong-

Pl. xiv, fig. 3. 
Description :—Elongately pentagonal, somewhat thin; 
margins, with age, thickened ; front margin thickened and 
bilobate. Apical angle about 98. 
Distinction :—From C. numztsmalis, narrower with a 
more thickened margin—the thickening begins before the 
bilobation, but it continues with it. 
Remarks :—Deslongchamp’s specimen may be a more 
aged example with much thickened margin. 
Localities and Strata:—Gloucestershire, Coaley, Lap- 
ley House (my collection), presumably /ammesonz-zone ;

tion); another example, Davidson collection, British 
Museum, smaller specimen under No. B 6926. Gloucester 
Gas Works, Mr Richardson’s collection. Somerset, Rad- 
stock, ‘‘Kilmersdon, avmatus”-zone, Mr Tutcher’s collec-
