370 The American Naturalist. [April, 
pronounces it not only the type of a new species, but a new genus also, 
which he calls Scutellaster. He believes that this genus may be re- 
garded as a synthetic or generalized type from which have been evolved 
Seutella on the one hand and Clypeaster on the other. (Am. Geol., 
Feb., 1895.) 
Recent collections from the Cretaceous Formation on Long Island 
have yielded forty-six additions to the previously recognized cretaceous 
flora of that region, nine of which are new species. They are described 
and figured by Mr. Hollick. (Bull. Torrey Bot. Club, Vol. 21, 1894.) 
The presence of silicified paleozoic fossils in the Long Island gravel 
at Lloyd’s Neck, and in the vicinity of Glen Cove, establishes its 
identity, in Mr. Hollick’s opinion, with the “yellow gravel” of New 
Jersey. The author is inclined to refer some of the gravels on Mar- 
tha’s Vineyard to the same horizon. In the same paper the author dis- 
cusses the Cretaceous clays of Long Island, and in view of the evidence 
of the fossil flora he correlates them wiih the Amboy clays of New Jer- 
sey, the Dakota group of the west, and the Lower Atane beds of Green- 
land. (Trans. N. Y. Acad. Sci., XIII, 1894.)
