FISHERY BULLETIN: VOL. 70, NO. 4 



majority of the specimens obtained were early- 

 stage larvae, hence spawned in the area of col- 

 lection. 



38. GEMPYLIDAE 



(112 occurrences, 370 larvae) 



Two kinds of gempylid larvae were widely dis- 

 tributed in the EASTROPAC area on ETP II: 

 larvae of Gempylus serpens Cuvier and Valen- 

 ciennes (71 occurrences, 152 larvae) and Nea- 

 lotus tripes Johnson (66 occurrences, 218 lar- 

 vae). 



Larvae of both species had a higher frequency 

 of occurrence and greater abundance on ETP II. 

 Distribution within the EASTROPAC area also 

 was different in the two multivessel surveys. 

 The more widespread distributional pattern for 

 Gempylus serpens was observed from the wider- 

 ranging ETP I survey. Over a third of the oc- 

 currences of Gempylus larvae were in the por- 

 tion of the ETP I pattern not replicated on ETP 

 II (Ahlstrom, 1971, Figure 13). Larvae were 

 taken throughout the ETP I pattern with as 

 many records from south of the equator as to 

 the north. In contrast, only three collections 

 were made to the south of the equator on ETP II 

 (Figure 4), but many more collections of Gem- 

 pylus larvae were obtained to the north of the 

 equator, particularly in the inner pattern occu- 

 pied by Rockaway. 



Changes in distribution of larvae of Nealohis 

 tripes in the two surveys were not as marked 

 as for G. serpens. On both surveys the majority 

 of the occurrences of Nealotus larvae were in 

 the inner half of the ETP pattern; heaviest 

 concentration of larvae on ETP II was in an 

 equatorial band between circa lat 5°N and 3°S. 

 Fewer Nealotus larvae were taken in the inner 

 pattern off Peru, between circa lat 3° and 15°S, 

 as compared with ETP I (ETP I, Figure 7). 



39. GOBIIDAE 



(53 occurrences, 384 larvae) 



Larvae of several families of shore or bottom 

 fishes have a much more widespread oceanic dis- 

 tribution than would be anticipated from the 



distribution of adults. In the EASTROPAC 

 area this applies particularly to larvae of Go- 

 biidae, Scorpaenidae, Labridae, Bothidae, and 

 Cynoglossidae. Based on pigmentation and 

 meristics a minimum of eight kinds of goby 

 larvae were taken. 



42. NOMEIDAE 



(229 occurrences, 1,460 larvae) 



And other Stromateiodei (14 occurrences, 



16 larvae) 



Four families of stromateoid, fishes were 

 taken on EASTROPAC cruises: Amarsipidae, 

 Nomeidae, Stromateidae, and Tetragonuridae. 

 Three of these families contain oceanic species 

 that are widely distributed in offshore waters; 

 only fishes of the family Stromateidae are con- 

 fined to coastal waters. Important papers deal- 

 ing with stromateoid fishes include Grey (1955), 

 Haedrich (1967, 1969), Haedrich and Horn 

 (1969),-" and Horn (1970). 



In the EASTROPAC area, only the nomeids 

 were common, occurring in about two-thirds of 

 the collections made on ETP II. Larvae were 

 obtained of two genera, Cubiceps and Psenes; 

 larvae of the former were the more abundant, 

 larvae of the latter were more diversified as to 

 species represented. 



Larvae of a species in the family Stromateidae, 

 Peprilus medius (Peters) , were taken at a single 

 station on ETP II, 46.135 (2 larvae), but a 

 larger collection was obtained at Oceanographer 

 Station OP 168 (16 larvae). 



Larvae of Tetragonuridae (11 occurrences, 

 12 larvae) occurred in an equatorial band be- 

 tween lat 2°N and 7°S, seaward of the Galapagos 

 Islands (Figure 17) . As noted in the first EAS- 

 TROPAC report, larvae of two species were 

 taken: T. cuvier i Risso and T. atlanticus 

 Lowe. 



Two specimens of Amarsipus carlshergi, de- 

 scribed by Haedrich (1969) as a monotypic rep- 

 resentative of a new family Amarsipidae, were
