Station B7, in this study, these species made up 

 47% and 10% respectively of the total number col- 

 lected. The sediments at this station visibly con- 

 tained large amounts of finer sediment material, silt, 

 not measured in the sediment analysis. 



Individual rock crabs, Cancer irroratus, were 

 generally found infrequently throughout the survey 

 area. During the summer, however, juveniles were 

 collected in abundance throughout the study area. 

 This can be attributed to the settling of larvae in 

 June. The large numbers collected in July consisted 

 principally of juveniles (0.5-1.5 cm carapace width). 

 The number declined rapidly after July, probably 

 due to predation by fish and other predators. 



Of the organisms collected in lesser numbers two 

 are of particular interest. Both of these are 

 polychaetous annelids that have only been reported 

 from areas far distant from the New York Bight. In 

 April 1966, on Station C3, four specimens of Pisione 

 sp. were collected. This genus had previously been 

 described from South African waters (M. Simpson, 

 Adelphi University, Garden City, Long Island, 

 N.Y., pers. comm., 1969). The second species was 

 tentatively identified asMagalone riojae, previously 

 known from Pacific waters (Simpson, pers. comm., 

 1969). This specimen was collected at Station D4 

 during the January 1967 cruise. Both species were 

 sent to authorities at the Smithsonian Institution, 

 Washington, D.C. for verification.
