Figure 3. — Distribution of larvae of the clupeid, Sardinops sagax (open square with dot, 1-50 larvae; closed square, 

 51 or more larvae), of the engraulid, Engraulis ringens (open diamond with dot, 1-100 larvae; closed diamond, 

 101 or more larvae), of the myctophid, Myctoplnnn asperum (open triangle with dot), and of the bothid flatfish, 

 Syacium ovale (open circle with dot, 1-100 larvae; large solid circles, 101 or more larvae). Small solid circles 

 represent other stations occupied on ETP II. 



4. ARGENTINIDAE 

 (32 occurrences, 58 larvae) 



In contrast to ETP I, from which three kinds 

 of argentinid larvae were obtained, only one 

 kind, Nansenki sp. A, was obtained on ETP II. 

 Larvae of Nansenki were taken in an offshore 

 equatorial band, between lat 8°N and 7°S. This 

 distribution is closely similar to that illustrated 

 for ETP I (Ahlstrom, 1971, Figure 2). 



5. BATHYLAGIDAE 

 (298 occurrences, 5,891 larvae) 



Larvae of two species of bathylagid smelts 

 were taken on ETP II: Bathijkigus nigrkjenys 

 Parr (293 occurrences, 3,787 larvae) and Leur- 

 oglossus stilbiiis urotramis (Bussing) (29 oc- 

 currences, 2,104 larvae). 



In comparable coverage on ETP I, 2,852 lar- 

 vae of B. nigrigenys were taken in 269 collec- 

 tions. The distribution of larvae on the two 

 coverages was strikingly similar (Ahlstrom, 

 1971, Figure 3). On the tv.o outer lines, occu-
