Figure 7. — Distribution of larvae of the gonostomatid, Vinciguerria spp. on ETP II. Collections of 1-100 larvae 

 are shown as open circles with dot in center, collections of 101 or more larvae as large solid circles; negative 

 hauls are shown as small solid circles. 



Ichthyococcus sp. 



(46 occurrences, 76 larvae) 



Maurolicus muelleri (Gmelin) 

 (47 occurrences, 773 larvae) 



All Ichthyococcus larvae taken on ETP II 

 were similar in appearance and have been re- 

 ferred to /. irregularis Rechnitzer and Bohlke. 

 Although widely distributed (Figure 6), all lar- 

 vae were obtained between lat 12°N and 4°S; 

 only three collections of Ichthyococcus larvae 

 were taken in the outer pattern occupied by 

 Washington. 



Larvae of M. muelleri ranked third in abun- 

 dance among gonostomatid larvae. As on ETP I, 

 (Ahlstrom, 1971, Figure 4) larvae of this spe- 

 cies were sampled in a rather narrow equatorial 

 belt, and none were taken seaward of long 

 112°W. This again is a striking instance of the 

 similarity in distribution of larvae on the two 

 multivessel cruises. Although the incidence of 

 occurrences of Maurolicus larvae was almost as
