Pycnogonidla : Pallene empiisa Wilson is 

 common. 



Limulus is abundant on the sand spit, 

 near the laboratory. 



Insects: The moist woodland about the 

 lakes and springs offers a remarkably rich 

 collecting ground for insects. One of the 

 most striking species, on account of its size 

 and abundance, is a form of the cricket- 

 grasshopper, Ceuthophilus 



Vertebrates : Some twenty species of fish 

 have been identified.* Dogfish and sand 

 sharks seem to be common. The stomachs 

 of nine of the former have been examined 

 during July of this year, and an aggregate 

 of eleven squillas, four spider crabs, four 

 hermit crabs, three other crabs, several 

 teleosts and a squid have been found in their 

 stomachs. 



Newts and frogs are common. Many 

 tortoises, snakes, water and land birds and 

 mammals are seen by the most casual ob- 

 server. 



I am indebted to Dr. D. S. Johnson, in- 

 structor at the Laboratory, for the following 

 description of 



THE FLORA ABOUT COLDSPRING HARBOR. 



The physiographic conditions of this re- 

 gion are considerably varied, as has been 

 noted above. On the outer coasts of the 

 north side of the island are extensive sandy 

 beaches, almost or completely washed over 

 by the sea during hard storms. 



Just above the reach of the ordinary tides 

 these beaches are partially covered with 

 Spartina juncea interspersed with Elms toxico- 

 dendron, a. copcdlina and Lathyrus viaritimiis, 

 while Arenaria peplodes Salsola kcdi, Cakile
