AX; p» 13k. 
Miocene.—Aldinga Bay (S.A). 
Pecten spondyloides having been ascertained to have all the 
interior characters proper to Spondylus, it seemed necessary to 
charge the specific name, as Spondylus spondyloides is hardly a 
binomial form, hence the names arenicola, Aldingensis. These 
two names were applied about the same time, though the first 
appeared earlier in print, and a lapse of memory is the sole reason 
for using the latter.
