but were not caught there during the opposite 

 season when the Monsoon Current replaces the 

 North Equatorial Current. During the SW mon- 

 soon none of the stations north of the Equator 

 between long. 50°E and 90°E contained adult 

 specimens (Figure 13b). Evidently this species 

 does not reach the coast of India. In the mid-water 

 trawls N. microps was caught between lat. 10°N 

 and 41°S (Figure lib), but north of lat. 2°N this 

 species was caught from only one station {Anton 

 Bruun cruise 3, station 146, lat. 10°09'N, long. 

 59°55'E). 



Atlantic Ocean 



From the Atlantic Ocean there are literature 



records of scattered occurrences of this species be- 

 tween lat. 40°N and 40°S. Moore (1952) reported 

 that this species occurred in the western Atlantic 

 north of the equator to lat. 40°-45°N, in the region 

 of the Gulf Stream. The most northerly record in 

 the eastern ocean was from lat. 59°39'N (Illig, 

 1930), although most other records lie south of lat. 

 40°N. In the present survey it was caught between 

 the Equator and lat. 40°N and was relatively more 

 abundant in the western ocean than in the east 

 (Figure 14a). It was not present in many samples 

 taken from the North Atlantic central gyre. There 

 were a few doubtful records of this species from the 

 Mediterranean Sea (Ruud, 1936; Bacescu and 

 Mayer, 1961). In the South Atlantic it was caught 

 by Lusiad and Atlantis 77-31 expeditions (Figure 

 lib).
