which the cHmate was considerably warmer than it is at the 

 present time as shown by the extension of various members of 

 the existing flora for many miles to the northward of their present 

 range. 



The writer gratefully acknowledges his indebtedness to Mr. 

 W. L. McAtee of the Biological Survey who through the courtesy 

 of Dr. C. Hart Merriam has examined not only some of the 

 present specimens but also other Pleistocene fruits and seeds 

 collected by the writer. The Biological Survey in its extensive 

 studies of the stomach contents of birds and mammals has ac- 

 cumulated large collections of fruits and seeds as well as experi- 

 ence in the identification of materials of this sort which is in- 

 valuable to the student of swamp deposits like so many of our 

 Pleistocene plant-bearing horizons. 



The following notes refer to the forms from New Jersey which 

 have been recognized in the present study.

In the existing flora the cypress reaches its northern limit in 

 southern Delaware and Maryland. Its range is becoming gradu- 

 ally restricted in the coastal plain as is shown by the sub-fossil 

 occurrences of stumps north of the present limit of pure stands. 



In the late Pleistocene its range was much more extensive 

 and fossil remains are found at numerous localities north of its 

 present limit of distribution. The most northerly of these occur- 

 rences is the present record based upon cone-scales from near 

 Long Branch, N. J., which is nearly 200 miles north of the 

 present northern limit of the species. 



Pinus Taeda Linne.

Cones and seeds of this species were recorded recently from 

 the Pleistocene of both eastern and western Alabama. In the
