lateral denticle's well-preserved are comparatively rare ; the most 

 usual condition in which they are found exhibits merely the 

 smooth portion of the crown.. This would account for Davis 

 placintr his specimens in the genus Oxyrhina. Agassiz records 

 this species from the Tertiary of Veteuil (or Verteuil), Chareute, 

 France.

Observations. — The European specimens referable to Lamna 

 compressa are said to show a range of form embracing the type 

 of L. macrota, by which name the species has been more re- 

 cently defined. As we have not hitherto foimd any teeth of 

 the macrota .series from any of our beds, but only those of the 

 compressa type, we think it better for the present to retain the 

 latter name for our representatives. 



Generally distributed through Europe in the Eocene and 

 Miocene, and in the Eocene of North America.
