Reinarhs. — This species has been generally confused with plumif- 

 era, but it lacks the plumes, which are the essential characteristic 

 of that species, and is considerably larger. Like flumifera it is a 

 pelagic form, widely distributed over the northern Atlantic, but 

 not likely to penetrate very far into the bay. Sars said of it : " To 

 judge from the structure of the oral parts, the animal must be of 

 a very rapacious nature, probably feeding upon other small pelagic 

 animals." ^^ 



ONCAEA MINUTA Giesbrecht 



Oncaea mlnuta Giesbrecht, Fauna uud Flora des Golfes von Neapel, vol. 19, 

 p. 603, pi. 47, figs. 3, 6, 26, 46, 59, 1892.— G. O. Sabs, Crustacea of Noi-way, 

 vol. 6, p. 217. pi. US, fig. 2, 1918. 



Occurrence. — About 25 specimens were obtained in a surface net 

 at Station C on August 22, 1920. A few females were also taken at 

 the surface at Station E on October 21, in a bottom net at Station F 

 on August 22, and in a bottom net at Station L on August 25. 



Remarks. — This little cyclopid was taken only late in summer and 

 in autumn, and in very small numbers, except at Station C. It has 

 not been reported as abundant anywhere and hence does not become 

 of real importance in the plankton. 



ONCAEA VENUSTA Philippi 



Oncaea venusta Philippi, Arch. Naturg., vol. 9, p. Ill, fig. 3, 1843. — Giesbrecht, 

 Fauna und Flora des Golfes von Neapel, vol. 19, p. 602, pi. 3, fig. 7 ; pi. 47, 

 figs. 2, 5, 13, 19, 39, 44, 48, 1892. 



Occurrence. — One hundred specimens were obtained at the surface 

 on the 100-fathom line in the outside ocean and 150 in the bottom 

 net. Six hundred were obtained at the surface in water 67 fathoms 

 deep, and 15 in the surface and bottom nets where the depth was 10 

 fathoms. A single female was found in the mouth of the bay. 



Remarks. — This is apparently a pelagic form and widely distrib- 

 uted in all the oceans, to judge from the localities given by various 

 authors. Hence it is not likely to be found inside of the very mouth 

 of the bay. 



SAPPHIRINA GEMMA Dana 



Sapphirina gemma Dana, Wilkes Expedition, Crustacea, vol. 14, p. 1252, pi. 88, 

 fig. 1, a-f; fig. 2, a-g; 1853. — Giesbrecht, Fauna und Flora des Golfes von 

 Neapel, vol. 19, p. 640, pi. 3, fig. 4 ; pi. 52, figs. 3, 4, 62, 64 ; pi. 53, figs. 19, 

 31, 32, 61 ; pi. 54, figs. 10, 12, 46 ; 1892. 



Occurrence. — A few specimens, including both sexes, were obtained 

 in the bottom net drawn from depths of 40 and 118 fathoms during 

 the trip to the 100-fathom line in the outside ocean.
