as Flabellaria magothiensis, Berry. These specimens occur in 

 the Magothy formation which Dr. W. B. Clark correlates with 

 the Cliffwood exposures, forming transition beds betvveen the 

 Albian and Cenomanian. D. P. Penhallow.

 in the eastern United States. (Amer. Nat. Bd.XXXlX. 

 p. 137—145. ill. 1905.) 



The occurrence of amber in the Cretaceous deposits of 

 Kreischer vil le, S taten Island, N. Y., was recorded in a 

 brief note in 1904, but the interest aroused necessitates a more 

 extended account. The amber is found in a Stratum charac- 

 terized by layers and closely packed masses of vegetable debris 

 consisting of twigs^ leaves and fragments of lignite and charred 

 wood. Most of the amber was found in a relatively thick accu- 

 mulation of finely comminuted lignite and charred wood. Much 

 of the material is in the form of drops or „tears", but there 

 are also irregularly shaped fragments varying' in size from a 

 large pin head to a hickory nut. They are usualiy more or 

 less transparent and yellowish or reddish in color. Previously 

 discovered deposits of Amber at Cape Sable, Maryland, have 

 been examined, and Dr. Knowlton identified Ciipressinoxylon 

 bibbinsü as the tree from which the amber had been derived. 

 In the Kreischerville beds, the close association of leafy 

 twigs of Seqiwia heterophylla and 6". reichenbachii, offers the 

 Suggestion that they may be the source of amber there, though 

 the remains of other Conifers such as Dammara, Widdring- 

 tonites, Jutüperus and Piniis also point to these plants as pos- 

 sible additional sources. D. P. Penhallow.
