lamelliform expansions which characterise the shells. Mr. McCoy holds that 
his A. iKiradoxa is not identical with A. planostilcata, J. Phillips; hut Mr. 
T. Davidson, who has compared the original specimens, says that it is, and I 
agree with him entirely. 
Sorizon and Localities. — A. planosulcata is chiefly developed in the 
uj)per strata of the Carhoniferous System. It is very abundant at Blacklion, 
Millecent &c., Ireland ; at Lowick, Longnor, Settle, and Bolland, England ; 
at Hawsdorf, Silesia ; and at Vise, Belgium. Messrs. De Keyserling and von 
Grhnwaldt found it in Bussia. Mr. W. B. Clarke found several specimens of 
it, nearly all internal casts, and all deprived of their lamelliform expansions, 
a circumstance which renders the determination of some of them doubtful. 
These specimens all come from Burragood, where they are found in a brownish 
limestone, except one which was found in a white limestone. A single speci- 
men, with the test well preserved, was found in an oolitic limestone near 
Dungog, on the Williams Biver.
