salt marshes. The barrens have been fairly well surveyed, but the marsh 

 needs more intensive study, and the relatively small areas of rich upland 

 which have not yet been too much disturbed by man should receive special 

 attention. It is certain that many forms now known only from Massachu- 

 setts and New Jersey, or even farther afield, will be discovered in this 

 area. The climate is, as a whole. Upper Austral, but the easterly part of 

 Long Island shows distinctly colder types and might best be -assigned to 

 the Transition zone. Unfortunately many of the early records are 

 merely "L. I."
