Figure 29. — Plankton sorter's master sheet — sample copy for stations 60.50 to 83.51, 

 cruise 6801. Numbers of hake larvae are out of order (last column is usually that of 

 sorters' initials) because hake counts were made after this cruise was completed. (See 

 note for Figure 25, indicating reasons for changes in numbers of anchovy larvae.) 



from the rest of the sample, this fact is 

 noted on the enumeration sheet and on the 

 back of the label in the vial in which they 

 would have normally been placed. Vials are 

 stored by numerical order of cruise and 

 cruise station in specially constructed card- 

 board boxes 3 X 5 X 7V2 inches with lids, 

 each containing 60 vials labelled appropri- 

 ately on the outside of the box by category 

 and cruise. Each cruise may have from 10 

 to 28 boxes depending on the abundance of 

 organisms and time of year of a survey. 



The boxes are stored by cruise in a special 

 area in the laboratory. 



REFERENCE COLLECTION 



A special reference collection, the "larva li- 

 brary", is kept adjacent to the identification lab- 

 oratory. The specimens in this collection are 

 usually the "best of a kind" and used for refer- 

 ence in identifying questionable material or rare 

 specimens whose characteristics may have been 

 forgotten over long periods of time. The ma- 

 terial is also used occasionally to train identifiers.
