peculiarly Pine Barren species, so far as southern New Jersey is con- 

 cerned, not occurring in West Jersey or the coast strip.

Among birds we find three species which breed regularly in the Pine 

 Barrens but not in West Jersey, i.e., Dendroica vigorsii, D. discolor and 

 Compsothlypis americana usnea. A number of species common in 

 West Jersey are however absent from the Pines. Among mammals 

 we have two species peculiar to the Pine Barrens, Evotomys gapperi 

 rhoadsi and Synaptomys cooperi, both boreal incursions, and several 

 West Jersey species which are absent, i.e., Sciurus carolinensis leucotis 

 and Tamias striatus. 



II. Lower Delaware Valley Region and Coast Strip. 



West Jersey from Trenton southward, west and southwest of the 

 Pine Barrens, supports a far greater variety of trees than the Pine 

 Barrens. The most plentiful species, not found in the latter region, 

 are Pinus virginiana, Juniperus virginiana, Quercus phellos* Q. 

 digitata,* Q. platanoides* Q. coccinea, Castanea deniata, Fagus ameri- 

 cana, Betula nigra, Ulmus americana, Hicoria alba, H. glabra, H. minima, 

 Carpinns caroliniana, Liriodendron iulipifera, Platanus occidentalis, 

 Diospyros virginiana,"^ Cornus florida, Liquidambar styraciflua,* 

 Prunus serotina and Ilex opaca.* 



Those marked with an asterisk are not found on the hilly country 

 which begins just west of the Delaware, nor north of the low ground 

 between Trenton and the Raritan. 



In this West Jersey district too we meet with many plants common 

 to the Pine Barrens but which do not extend farther north or west. 

 Such as 



Woodwardia areolata Euphorbia ipecacuanoe 



Woodwardia virginica Gerardia purpurea 



Iris prismatica Eupatorium maculatum 



Lilium superbum Eupatorium album 



Poly gala nuttalli _ Eupatorium rotund i folium 



Rhexia mariana ^ ^ ^ Euthamia caroliniana, etc.
