spinose radial plate with two facets for arms, and columns of at 

 least two generic types occur. 



Trilobites. — Two, or perhaps three, occur representing the 

 genera Phillipsia and Griffitliides, which appear to be distinct 

 from any of the described species. 



Fusulina. — A few water-worn specimens have been found on 

 the beach at Itaituba. 



A few fish teeth and two species of cephalopods also occur, 

 but the notes regarding them have been lost. One of the ceph- 

 alopods is mentioned by Prof. Hartt in his description of the 

 Tapajos section, which from its position is now thought to be 

 probably of Devonian age.
