222 BIOLOGICAL SURVEY OF 



C. HAMATus (Lilljeborg). (G. 0. Sars, 1902, p. 76, pi. 52.) 

 Common in surface tow at D 104. 



Temora Baird 

 T. LONGicoRNis (0. F. Mtiller). (G. 0. Sars, 1902, p. 97, 

 pis. 65, 66.) A common species in the plankton, especially 

 early in the summer. Stations : D 1, 30 ; P 4r-6, 10, 11. 



EuRYTEMORA Giesbrecht 

 E. HERDMAisri Thompson and Scott. (Thompson and Scott, 

 1897, p. 78, pi. 5, figs. 1, 8, 10.) Rare in plankton at P 6, 11. 



Pontellidae 

 Anomalocera Templeton 



A. PATERsoNii Templeton. (G. 0. Sars, 1902, p. 139, pis. 

 92-94.) A few taken in surface tow at D 104. 



AcARTiA Dana 



Steuer (1915) in dividing the genus Acartia into a number 

 of subgenera distributed Dana's two identifiable species, negli- 

 gens and tonsa, into subgenera neither of which bore the 

 name Acartia, as one of them by rights should have. I here 

 designate Acartia negligens Dana as the type of the genus 

 Acartia, and hence the type of the typical subgenus which 

 must under the rules bear the name Acartia {Acartia) 

 negligens. 



A. Acaetiura) longiremis (Lilljeborg). G. 0. Sars, 

 1903a, p. 149, pis. 99, 100.) Taken once in plankton at P 11. 



A. (Acanthacartia) bifilosa (Giesbrecht). (Gurney, 1931, 

 p. 230, figs. 329-344.) Occasionally common in the plankton. 

 Stations : D 30 ; P 5, 10. 



Tortanus Giesbrecht 

 T. discaudatus (Thompson and Scott). (Thompson and 

 Scott, 1897, p. 80, pi. 6, figs. 1, 10, 11; pi. 7, figs. 1, 2.) Rare 

 at the surface during the day, but often abundant there at 

 night. Stations: P 6, 10, 11.
