An attentive consideration of the diagnoses and figui-es of the two 

 shells, has forced the writer to the conclusion that the A. ramosus of 

 Meek is synonymous with the A. Velledoe of Michelin and other European 

 palaBontologists. 



Mr. Meek, after admitting that the shape and surface markings of both 

 are alike, goes on to say : " When we compare the septa, however, they 

 are at once seen to present marked differences, such as are clearly incom- 

 patible with specific identity, if D'Orhigny's figures are correct'* The 

 qualification italicized shews that Meek had not compared his shell with 

 either Pictet's or Stoliczka's descriptions or illustrations of A. VelledxB.
