The presence of 15 species in the New England 

 region (Table 12) , compared with only 3 species 

 in the Middle Atlantic and 5 species in the South- 

 ern area, is due, in part, to more intensive sam- 

 pling in the New England waters. However, the

recovery of five species in samples from the 

 southeastern coast of the United States where 

 the sampling was sparse, indicates a relatively 

 diverse mysid fauna inhabits that region. Thor- 

 ough sampling will undoubtedly disclose a num- 

 ber of additional species (new species plus new 

 records for presently recognized species) in all 

 sections of the coast, though the Middle Atlantic 

 region can be expected to contain the fewest 

 species of mysids. 



BATHYMETRIC DISTRIBUTION 



The overall bathymetric range at which 

 NMFS mysids were collected is from 1 to 700 m 

 (Table 11). In general all depth zones are 

 rather evenly represented without a preponder- 

 ance in any one zone. In Table 13 the species 

 are listed under five categories based on the 

 watei' depths from which they were most fre- 

 quently caught. Two sjiecies were found only 

 in the intertidal zone. Five species are typically
