"Protozoa" 



Dissodium was included with 



"Misc. Organisms" for cruises 1 

 through 3. No protozoa were counted 

 in samples in which radiolaria were 

 so numerous as to make a reasonable 

 estimate impossible, and are so noted 

 in tables in such instances. 



"Coelenterata" - separation of necto- 



phores on some siphonophores made it 

 impractical to attempt to match 

 pieces and caused some variation in 

 numbers. Colonial hydroids were not 

 considered plankton. 



"Chaetognatha" - only whole chaetognaths 

 or major fragments (such as head 

 with portion of body attached) were 

 counted. 



"Misc. Mollusca" - all mollusca except 

 pteropods without spiral shells. 



"Larvacea" - no irregularities noted. 



"Misc. Tunicata" - probable inaccura- 

 cies due to fragmentation of 

 specimens. 



"Misc. Organisms" - all groups not 

 listed above, plus invertebrate 

 eggs and unidentified organisms. 

 No "Misc. Organism" counts were 

 made for samples in which echino- 

 derm larvae were too thick and 

 matted to make a reasonable esti- 

 mate and are so noted in tables 

 in such instances. 



"Misc. Worms" - difficulty in estimating 

 individuals from fragments of Poly- 

 chaeta may be reflected in an over- 

 estimation of total numbers. Rotifers 

 and sipunculoids, if present, were 

 included in "Misc. Organisms." 



"Copepoda" - nauplii included with "Misc. 

 Crustaceans." 



"Ostracoda, Mysidacea, Amphipoda, Isopo- 

 da, Stomatopoda" - no irregularities 

 noted. 



"Euphausiacea" - nauplii included with 

 "Misc. Crustaceans." 



"Shrimp" - Natantia according to Pratt 

 (1935), including Peneidea, Car idea, 

 plus Stenopldea. Counts include lar- 

 vae beyond nauplius stage, nauplii 

 were included with "Misc. Crusta- 

 ceans." Gurney (1942) was generally 

 followed in identification of larvae. 



"Crabs" - Reptantia according to Pratt 



(1935), including Palinura, Astacura, 

 Anomura, and Brachyura. Gurney 

 (1942) was generally followed in 

 identification of larvae. 



"Misc. Crustaceans" - all crustacean 



groups not listed above, plus uniden- 

 tified crustaceans, and nauplii of 

 copepods, euphausiids, and shrimp. 



"Pteropoda" - all except those with 

 spiral shells.
