AHLSTROM: FISH LARVAE IN EASTERN TROPICAL PACIFIC 



vae per positive haul ranged from 1 to 72 (aver- 

 age 7.0) ; 15 collections contained 25 or more 

 larvae, most distributed between lat 7° and 20° S. 

 Distribution of the larvae of S. eveiinanni on 

 EASTROPAC I is illustrated in Figure 12. 



but larvae of the two species are differently pig- 

 mented. T. oculeiis occurs in a broad coastal 

 band between Panama and Chile, having in this 

 respect a complementary distribution of that of 

 T. mexicamis off California and Baja California. 



Triphoturus spp. ( 140 occurrences, 506 larvae) 



Larvae of at least tvvo species of Triphoturus 

 were taken in the EASTROPAC area. Of par- 

 ticular interest are larvae of Triphoturus oculeus 

 (Carman); this species previously was consid- 

 ered a synonym of T. mexicanus (Gilbert), 



14. PARALEPIDIDAE 

 (290 occurrences, 1,648 larvae) 



Larvae of Paralepididae were taken in ap- 

 proximately 60 % of the stations occupied on 

 EASTROPAC I. The area of heaviest concen- 

 trations was in an equatorial band between lat 

 5° N and 5° S (Table 16). Two species are

 on EASTROPAC I. Collections of 1 to 25 larvae are shown as large circles with dot in center, collections of 

 26 or more larvae as large solid circles; negative hauls are shown as small solid circles.
