GOPALAKRISHNAN: ZOOGEOGRAPHY OF NEMATOSCELIS 



Figure 7. — Worldwide distribution ofNematoscelis based on mid-water trawls: a - A^. gracilis "old" and "new" forms; b - N. difficilis and 

 A^. megalops. (Solid lines represent approximate boundaries of distribution of old form, broken lines represent those of new form, and 

 wavy lines represent distributional boundaries of AT. difficilis and N. megalops. Boundaries are based on literature records and present 

 evidence.) 



Atlantic Ocean 



Nematoscelis megalops appears to have a wider 

 north-south range in the Atlantic than in other 

 oceans. The southernmost record in the North At- 

 lantic was in the region of the Canary Current 

 (Figure 8a). Larvae and juveniles were frequently 



caught between lat. 40°N and 53°N. Literature 

 records of this species in the North Atlantic are as 

 far north as lat. 68°N (Zelikman, 1964). Moore 

 ( 1952) recorded this species from lat. 35°N to 55°N. 

 It occurs in the Mediterranean Sea (Ruud, 1936). 

 In the South Atlantic it was collected by the 

 Lusiad Expedition between lat. 25°S and 30°S
