 Arizona and southern Florida through Mexico and the West

A TiLiA FRO.M THE Xew Jer.sev PLEISTOCENE. — In the Flora 

 of the Amboy Clays, Professor Newberr}' described a single im- 

 perfect leaf from Fish House, N. J., under the name oiTiliaepJiylhim 

 diibiiun, remarking that it was very distinct from any other plant 

 yet found in the Amboy Clays and that it resembled some leaves 

 of the basswood, such as could be collected in almost any forest. 



In the Annual Report of the State Geologist of New Jersey 

 for 1896, the year that Newberr)''s monograph was finally issued, 

 Mr. Lewis Woolman discusses in great detail the stratigraphy of 

 the Fish House clays and their fossils, conclusively showing that 

 the dark clays at Fish House are of Pleistocene age and not Cre- 

 taceous, as they had been regarded by Lea, Whitfield, Uhler, 

 Newberry, and others. However, the Cretaceous is directly 

 beneath these Pleistocene clays, and at the present time the floor 

 of the pit consists of a somewhat indurated layer forming the 

 contact with what is now called the Magothy Formation of Up- 

 per Cretaceous age, but which in Newberry's day was not differen- 

 tiated from the Amboy Clays or Raritan Formation. Since the 

 lighter Cretaceous clays underlie the dark Pleistocene clays at 

 this point it was not possible for Woolman to determine from 

 which bed the basswood leaf had come, as no additional speci- 

 mens were found by him, the presumption being, however, that it 

 came from the Pleistocene. 



During the past year or two the writer has visited this most 

 interesting locality as occasion has offered, each time making a 

 careful search for plant fossils. It cannot be said that such 

 search proved very successful. A fragmentary maple leaf (Acer) 

 was collected at one point, and the clay was found to contain in 

 places a large number of seeds, of which only the gum [Ayssa) 

 has thus far been definitely recognized. Fortunately, hpwever.
