separately tabulated in Appendix Table 3: 

 Mac)-oparalepis macruriis Ege (35 occurrences, 

 44 larvae), and Siidis atrox Rofen (13 occur- 

 rences, 15 larvae) . These two species have such 

 characteristic larvae that they are readily identi- 

 fiable. The larvae of Macroparale.pis macruriis 

 were widely distributed in the EASTROPAC 

 area, except in the inner pattern occupied by 

 Alaminos (Fig. 7). In contrast, the larvae of 

 Sudis atrox were confined to the central water 

 mass of the South Pacific (Fig. 7) . This species 

 was originally described from the central water 

 mass of the North Pacific (Rofen, 1963 ; see also 

 Berry and Perkins, 1966). Preliminary study 

 of the other paralepidid material indicated that 

 a number of species were represented, but that 

 the most common larva was the form illustrated 

 by Ege (1953, Fig. 27), simply as "Lestidium 

 spec." 



15. EVERMANNELLIDAE 

 ( 27 occurrences, 38 larvae ) 



The larvae of Evermannellidae in the EAS- 

 TROPAC area have not yet been worked out in 



detail. Three species of Evermannellidae are 

 known to occur: Coccorella atrata (Alcock), 

 Evermannella indica Brauer, and a form with 

 a higher anal fin count than is found in these 

 two species. The identity of the latter, known 

 only as yet from larval specimens, remains un- 

 certain. Although larvae of Evermannellidae 

 were not common, the occurrences were distrib- 

 uted over much of the EASTROPAC pattern, 

 except nearshore. 



16. SCOPELARCHIDAE 

 ( 142 occurrences, 329 larvae) 



Scopelarchids are widely distributed in the 

 eastern tropical Pacific, usually occurring in 

 small numbers, i.e., one to three larvae per haul. 

 Only 15 ',r of the positive hauls contained larger 

 numbei's of larvae, i.e. 4 to 20 larvae per haul. 

 Scopelarchid larvae were most common between 

 lat 10° and 20" N, as is shown in Table 17. 



There are at least five species of scopelarchids 

 represented by the larvae, and perhaps si.x. I 

 have not attempted to attach specific names to 

 most of the kinds because the adult scopelarchids
