Gkaptolithus brtonoides. 



Description. — Frond composed of four short simple branches, 

 united at the base by a vinculum, and terminating below in a 

 minute radicle ; branches short, comparatively broad, obliquely 

 and strongly striated from the base of the serratures to the outer 

 edge of branch ; serratures moderately oblique, the outer and 

 inner margins making very nearly a right angle ; mucronate at 

 the tip ; about twenty-four to twenty-eight in an inch. 



Of several specimens in the collection none of the branches ex- 

 ceed an inch in length, while they are almost one eighth of an inch 

 in width from the tip of the solid part of the serratures to the outer 

 edge. They are all strongly striated from the base of the serra- 

 tures to the outer margin, the strise sometimes a little curved. The 

 serratures are usually slightly oblique, or with the longer sloping 

 side directed towards the base of the branch, and the shorter side 

 advanced a little beyond a right angle to the rachis. In one spe- 

 cimen, where the branches are less than five-eights of an inch in 

 length, the serratures seem to be equally or nearly equally sloping 

 on the two sides from the tip to the base. 



The vinculum is obscure, and from the mode of imbedding 

 .in many specimens, this part might be inferred to be absent. 



Locality and Formation. — Point Levy, Hudson River Group.
