Xystreurys liolepis - originally misidentif ied as Paralichthys 

 californicus; all specimens reidentif ied. 



Glyptocephalus zachirus - all specimens examined. 



Microstomus pacificus - all specimens examined. 



Pleuronichthys spp. - all larvae of this genus and constituent 



species were examined and assigned to species; residuals are 

 unavailable specimens. 



Psettichthys melanost ictus - all specimens examined. 



COMPUTER ENTRY AND EDITING 



Each taxon on the original identification sheets was given a 

 3-digit code based on the list of codes in Haight et al. (1979). 

 Taxon codes and counts from these sheets were keypunched by 

 cruise and station, along with pertinent station and tow data and 

 entered into the VAX 11/780 computer at the University of 

 California, San Diego, Computing Center. After entries were 

 completed for an entire year, print-out listings of taxa and 

 counts on each station were compared with the original data 

 sheets to eliminate keypunch errors. Next, data in the file were 

 cross-checked with data on an existing file which contained: 

 station and tow data; numbers of eggs of sardine, anchovy, and 

 saury; numbers of larvae of sardine, anchovy, hake, jack 

 mackerel, and Pacific mackerel; total number of fish eggs; and 

 total number of fish larvae. 



Discrepancies in ichthyoplankton data in these two files 

 were corrected by inspecting original records from the sorting 

 laboratory, the original ichthyoplankton identification sheets, 

 and the samples themselves. Station and tow data discrepancies 

 between the two files were corrected by reviewing ships' logs and 

 deck tow sheets, original records from the sorting laboratory, 

 cruise announcements, publications, header information on the 

 ichthyoplankton identification sheets, and station plots 

 generated for each cruise. Eventually all station and tow data 

 were checked by comparing these sources. 



The corrected ichthyoplankton data base was then examined 

 statistically and outliers were found and checked as above. 

 Distributional plots were then prepared for each taxon and these 

 were checked by reviewing the data sources mentioned above and by 

 examining archived specimens. A listing of each taxon by station 

 (Table 4) was produced, which became the primary document for 

 subsequent checks. Misidentif ications found in geographic 

 outlier checks and other misidentif ications and data problems 

 discovered in the course of examining archived samples resulted 

 in several iterations of Table 4. Finally, totals in Table 4 

 were checked against annual summaries of incidence and abundance
