both surface to 20 fathoms and 20 to 100 

 fathoms off Cape Canaveral. 



Sagjtta serratodentata . anopenocean species 

 widely distributed over the Continental Shelf, 

 and noticeably absent from most Gill stations 

 bordering the coast, appeared in greater 

 numbers in 20 to 100 fathoms than in surface 

 to 20 fathoms. 



Sagjtta hispida , limited to Gill stations 

 nearest the coast, was more abundant at the 

 surface to 20-fathom stations off Cape 

 Canaveral than any other stations along the 

 south Atlantic coast. 



Sagitta minima occurred in maximum abund- 

 ance along the edge of the Continental Shelf, 

 with only a trace at one station in surface to 

 20 fathoms. 



Sagitta bipunctata . seldom abundant but 

 widely distributed over the outer portion of the 

 shelf and across the Florida Current, is taken 

 consistently in offshore waters. 



Sagitta hexaptera , taken occasionally over 

 the outer edge of the shelf, but principally in 

 the Florida Current, appeared in low numbers 

 in 20 to 100 fathoms off Cape Canaveral. 



Krohnitta pacifica , never abundant, but wide- 

 spread from the coast across the Florida 

 Current, appeared in all samples in the Cape 

 Canaveral Area but most abundantly in 20 to 

 100 fathoms. 



Pterosagitta draco , widely distributed, from 

 every Gill station beyond the 10-fathom curve 

 along the south Atlantic coast, appeared in 

 one Cape Canaveral sample inside the 20- 

 fathom curve but in all samples fronn 20 to 

 100 fathoms. 



Two species identified from T. r£. Gill 

 samples off the southeastern coast of the 

 United States, Sagitta lyra and Krohnitta sub- 

 tilis , did not occur in the samples from the 

 Cape Canaveral Area.
