Nearly rclat' d to A. ciirouatus, Bnig. frum the

Of the type of Peiisphinetes tyrannus Neumayr; 

 and allied to several of the Oolitic Planulati. 



More like tlie Oolitic than the CretaceouH Macrti-

Scarcely to he di.stingiushcd from P. Heddingto-

A genus most ciiaracteristic of the Oolitic epoch. 



The rihhed Pleuromyoe do not appear to range up- 

 wards into the Cretaceous, but this shell may 

 he a Panopoea. 



Very doubtfully referred to this Tithonic and Middle 

 Oolite species. Quite likely both distinct and 

 new.

 previously described from other localities and by ditierent writers,
