Figure 16. — Distribution of larvae of the beryciform family Melamphaidae on ETP II. Collections of 1-10 larvae 

 are shown as open circles with dot, collections of 11 or more larvae as large solid circles; negative hauls are shown 

 as small solid circles. 



word "specimen" is used intentionally because 

 some juveniles as well as larvae are included in 

 the above counts. A number of the specimens 

 were x-rayed in order to obtain vertebral counts 

 to verify identification. All occurrences of the 

 small tropical saury, Cololabis adocetus, were 

 along long 95°W at nine contiguous stations 

 (Figure 14) ; surface temperatures ranged be- 

 tween 19.5° and 21.5°C at these stations. Scom- 

 beresox larvae occurred in a broad coastal belt, 

 shoreward of C. adocetus, extending from near 

 the equator to the southernmost line occupied on 

 ETP II (Figure 14); surface temperatures 



ranged between 15.8° and 19.5°C at these sta- 

 tions. Actually Scomberesox eggs and larvae 

 were commonly taken in the pattern occupied 

 by YelcJw off Chile as part of ETP II— MAR- 

 CHILE VI. Collections obtained from surface 

 tows as well as from oblique net hauls were 

 available from MARCHILE VI. Five short lines 

 of stations normal to the trend of the Chilean 

 coastline were occupied on MARCHILE VI, be- 

 tween lat 18°30' and 33°S. Scomberesox eggs 

 and larvae were sampled best in surface hauls. 

 Scomberesox eggs were taken in 17 of 20 surface 

 hauls and Scomberesox larvae in 10 surface
