REPORT OF THE DIRECTOR AND STATE GEOLOGIST 1901 rl05 



trips were made to Long Island, to localities where crabs were 

 taken for market, to the United States Fish Commission at 

 Washington and to Crisfield Md. It was finally decided to 

 settle at Bay Shore L. I., where the department of zoology of 

 Columbia University had established a summer station. Through 

 the courtesy of Dr Crampton of Columbia, the facilities of the 

 station were put at the disposal of the museum, and much valu- 

 able material, otherwise unobtainable, was secured through his 

 assistance. Practically the entire summer was spent here in 

 collecting museum material, studying the development of 

 Pcmopeus, the mud crab, and gathering a series of specimens 

 illustrating the embryonic stages of that form and of Callinectes. 

 A number of trips were made to various places, where catching 

 and shedding crabs for the market was carried on, and many 

 facts of scientific and economic importance were obtained. 



Dr Paulmier also spent a portion of his vacation at the bio- 

 logic laboratory at Woods Role, and considerable material not 

 elsewhere obtained was there collected. 



During July and August 1901 extensive collections of fishes 

 were made in Great South bay, L. I., by Dr Tarleton H. Bean. 

 These collections include 49 species, of which all except three 

 are marine. Though the apparatus for taking fishes was much 

 more extensive and elaborate than that employed in 1898, the 

 number of species secured is unusually small, owing to excep- 

 tional natural conditions. It seems probable that the abundant 

 rainfall during the spring and early summer reduced the salinity 

 of the water of Great South bay to a point at which it proved 

 uninviting to most of the fishes which usually migrate from the 

 south in summer, enter the bays of Long Island, and remain 

 there frequently till the late fall. 



The same observation was made in bays and sounds as far 

 north as Cape Cod. 



The only southern species obtained during July and August 

 were the following: Hyporhamphus robwti, one example; Kirt- 

 landia vagrans, two individuals; TracMnotus falcatus, one young 

 specimen; Leiostomus xanthurus, two examples; Alutera schoepfii,
