The single specimen of this well-defined species here figured is the only one thus 

 far found within the insular area, although it is not rare in both the Raritan and 

 Cliff wood formations in New Jersey. It occurs in the upper Cretaceous of Europe, in 

 the Patoot beds of Greenland, and has recently been identified from the Judith River 

 beds of Montana, a but, so far as I am aware, has never been recorded from any 

 typical Dakota group locality. We have generally regarded it as one of the charac- 

 teristic eastern Cretaceous species which served to indicate the closer relationship 

 with the Cretaceous of Greenland and Europe than with that of the western United 

 States, but this view, in the light of the above-mentioned discovery, must now be 

 somewhat modified.

Fragmentary remains of this species occur in the clays at Kreischerville, Staten 

 Island, but thus far they have not been found elsewhere within the area covered by 

 this monograph, although the species is abundantly represented in the Amboy clays 

 of New Jersey, and is reported from the Potomac of Virginia and the Judith River 

 beds of Montana. It is a characteristic element in the Cretaceous of Europe, and 

 it is somewhat remarkable that it has not been recorded from any of the Greenland 

 horizons.
