based on survey specimens include Paralichthys dentatus (Smith and Fahay 

 1970) and Scomber scombrus (Berrien 1975) . Similar papers on other species 

 are in preparation or planned. 



METHODS 



Sampling procedures described by Clark et al . 1969, Smith 1973, and 

 Fahay 1974 are only summarized here. On each cruise we sampled at 92 

 stations situated on 14 transects (Figure 1) . Stations were shoreward as 

 close to the beach as the vessel could operate, and seaward to near the 

 continental shelf edge. We completed eight cruises from December 1965 

 to December 1966. In addition, on an incomplete cruise in September 1966 

 (cruise D-66-11) we sampled four transects between Martha's Vineyard, 

 Massachusetts and Barnegat Inlet, New Jersey. 



Two Gulf V samplers (Arnold 1959) with 0.52-mm mesh netting were 

 usually towed simultaneously at each station. All step oblique tows were 

 30 min at a speed of 9.3 km/h (5 kt) . In a standard tow the nets were 

 lowered in six 3-m depth increments, or steps, and towed for 5 min at 

 each depth. One Gulf V sampled from to 15 m, and the other from 18 to 

 33 m. Alterations to this standard towing procedure, necessitated by 

 varying water depth are shown in Figure 2. Surface temperature was 

 measured with a stem thermometer. Mechanical bathythermographs provided 

 temperature data with water depth. Salinity was measured with an in situ 

 induction salinometer at 5-m depth increments to a maximum of 50 m. 



All fish eggs and larvae were removed by successively sorting small 

 portions of each plankton sample under dissecting microscopes as described 

 in Clark et al . (1969). The responsibility for identification of eggs
