BLOCK ISLAND. 57 



1. Gleichexia gracilis Heer (?). 



(PI. HI. Fig. 3.) 



GleicJienia gracilis Heer, Fl. Foss. Arct., Vol. iii (Kreidefl.), 

 p. 52, pi. X, figs, i-ii ; p. 98, pi. xxvi, figs. 13 b, c, d. 

 Our specimen is almost certainly a Gleichaiia, but the pinnules 

 are more acute and runcinate than in Heer's figures of G. gra- 

 cilis. I prefer, however, to refer it provisionally to this species 

 rather than to found a new one upon such a small fragment. 

 Locality : Near Black Rock Point, Block Island. 



2. Dammara microlepis Heer (?). 



(PI. HI. Figs. 9 a, b.)

p. 55, pi. xl, fig. 5. 



The specimens figured on our plate are undoubtedly referable 

 to the organisms which have been called Dammara and Euca- 

 lyptus, from the Cretaceous of America and the Old World. 

 The ones under consideration are, however, smaller than any 

 which have been previously figured and might perhaps be re- 

 ferred to a new species, but, in view of the limited amount of 

 material and its fragmentary condition, I have thought it best 

 to refer the specimens provisionally to Heer's species. 



Locality : Ball's Point, Clay Head, Block Island. 



3. Moriconia cyclotoxon Deb. and Ett. 



(PI. III. Fig. 10.) 



Moriconia cyclotoxon Deb. and Ett., Urwelt. Acrob. Kreidegeb. 



Aachen und Maestricht, p. 59 [239], pi. vii, figs. 23-27. 



In regard to this specimen there can be no doubt. It is one 

 of the most abundant species found in the Amboy clays, at 

 South Amboy, N. J., and is also known from Staten Island and 

 the Arctic regions. 



Specimens figured by Herr (Fl. Foss. Arct. Vol. vi, Abth 

 II, pi. xxxiii, figs. 1-9) and by Newberry (Fl. Amboy Clays 

 Monog. U. S. Geol. Surv., xxvi, pi. x, figs. 1 1-21) are far bet- 

 ter for comparison than are the original figures of Debey and 

 Ettinghausen. 



Locality : Near Black Rock Point, Block Island.
