NORTH AMERICAN INVERTEBRATE PALEONTOLOGY. 573 



a discussion of the interrelationship of the forms of Paradoxicles and 

 descriptions of species and varieties. The new species are ParadoxUhn 

 eteminiciis, with five varieties, breviatus, suricoides, malicitus, quaeoensis, 

 pontijicalis; Paradoxides acadicus, and P. lamellatus Hartt var. loricatus. 

 The figures are very fair.

The author identifies a few American forms with European ones in 

 addition to those already identified by Mr. Heilprin, and describes the 

 following new species from the Eocene sands of Claiborne, Ala. : Tibiella

 new genus o( Pteropoda, but no synopsis of generic characters is given.

 The author notes the parallel position occupied by the Laramie group 

 in Northwestern America and the intertrappean beds of the Deccan in 

 Hiudostan, both being placed between the Cretaceous and Eocene, and 

 the resemblance of the fossil faunas is well brought out by a compar- 

 ative list.
