Figure 4. — Distribution of larvae of the bathylagid, Leurofflossus stilbius urotranus (open triangle with dot, 1-100 

 larvae; closed triangle, 101-500 larvae, and triangle with bisecting line, 501 or more), of the gempylid, Gempylus 

 serpens (open circle with dot), and of the trichiurid, Diplospinus multistriatus (open square with dot). Small 

 solid circles represent other stations occupied on ETP II. 



pied by Washington, no larvae of B. nigrigenys 

 were taken beloM^ ca. lat. 4°S. Absence of larvae 

 of this species from the South Pacific central 

 water mass was not as conclusively documented 

 as on ETP I, primarily because of the paucity 

 of coverage within the central water mass on 

 ETP II. Counts of larvae exceeded 100 spe- 

 cimens per haul in five samples, taken between 

 0° and lat 3°S and long 85° to 92°W. 



Larvae of Lem^oglossus stilbius urotramis 

 were taken in 29 collections; all but 2 of which 

 were obtained in a compact area shoreward of 

 the Galapagos Islands between 0° and lat 10 °S 



(Figure 4). The distribution of larvae of this 

 species is one of the few that shows a striking 

 contrast between ETP I and ETP II. On ETP I 

 about half of the occurrences were to the north 

 of the equator between 0° and lat 8°N (18 oc- 

 currences, 218 larvae — Ahlstrom, 1971, Figure 

 2), compared with only one occurrence, one lar- 

 va in this area on ETP II. The distribution 

 south of the equator was essentially similar on 

 both surveys; on ETP I, 1,672 larvae were taken 

 in 19 collections between 0° and lat 14 °S, with 

 the heaviest concentration of larvae in hauls 

 taken between lat 3° and 6°S.
