The temperature here dropped 4° in 50 meters from a high 

 value at the surface, and 8° more at the 100-meter level. 

 Fourteen species were found at the surface, 30 in the 50-meter 

 tow, and 36 in the 100-meter tow. Twenty-three species (46 

 per cent) were confined to a single depth and only 4 were 



records, Corycaeus and Oncaea are each represented b>' a single 

 species in the surface tow, but the former is better represented 

 in the SO-meter tow and the latter becomes very abundant in 

 the 100-meter tow. This last tow also contains the only record 

 of Pareuchaeta grandiremis and one of two Atlantic records 



present in ail three tows. In contrast with the preceding of Microcalanus pygmaeus.
