Figure 10. — Distribution of larvae of the myctophiform families Evermannellidae (open triangle with dot), and 

 Scopelosauridae (open squares with dot, 1-25 larvae, closed squares, 26 or more larvae) and of the perciform 

 family, Labridae (open circle with dot) ; negative hauls are shown as small solid circles. 



taken on the outer line of stations along long 

 119° W; the remainder were taken in an equa- 

 torial band between lat 2°S and 4°N (Figure 

 10). This distribution is less widespread than 

 that encountered on ETP I; however, 17 of the 

 records of occurrence on ETP I were in the 

 southern portion of the pattern not covered on 

 ETP II. 



14. MYCTOPHIDAE 



(352 occurrences, 64,009 larvae) 



Larvae of Myctophidae were more abundant 



on ETP II than on ETP I; the increase in 

 abundance of myctophid larvae per haul in ETP 

 II over ETP I was 1.63 x . Much of the increase 

 was due to the greater abundance of larvae of 

 the dominant species, Diogenichthys laternatus 

 (Garman), although a number of kinds of myc- 

 tophid larvae were taken in somewhat greater 

 abundance, and only a few kinds were taken 

 in lesser numbers per haul (Table 19) . To show 

 changes in relative abundance of myctophid lar- 

 vae between the two multivessel cruises, I have 

 arranged the more common kinds in order of 

 their relative abundance on ETP II as compared
