COKYCAEUS ELONGATUS Claus 



Corycaeus elongatus Claus, Die frei lebenden Copepoden, p. 157, pi. 24, figs. 3, 

 4, 1863. — GiESBKECHT, Fauna und Flora des Golfes von Neapel, vol. 19, p. 

 674, pi. 15, figs. 6, 7, 1892. 



Occurrence. — A few specimens, including both sexes, were taken in 

 n bottom net at Station C on December 20, 1920, and a few females 

 were captured in a surface net in the outside ocean on August 21, 

 1921. 



Remarks. — This copepod advanced a little farther into the bay 

 (luring winter than Corycella carinata. According to the authors 

 the present species does not seem to be abundant anywhere, but is 

 always found in small numbers. This fact and its small size make 

 it of no economic importance in the plankton of the bay.

CORYCAEUS SPECIOSUS Dana 



Corycaeus speciosus Dana, Wilkes Expedition, Crustacea, vol. 14, pt. 2, p. 1220, 

 pi. 86, fig. 1, 1, a-d, 1853. — Giesbkecht, Fauna und Flora des Golfes von 

 Neapel, vol. 19, p. 673, pi. 51, fig. 40, 1892. 



Occurrence. — These four species of Corycaeus were found in small 

 numbers at the surface on the 100-fathom line, and were not taken 

 within the limits of the bay. 



Remarks. — From the locality where they were found it will be 

 seen that these four species are pelagic copepods not likely to be 

 taken within the limits of the bay. Moreover they are not found 

 anywhere in abundance but always in very small numbers. To- 

 gether with their small size, this prevents them from becoming of 

 economic importance. 



CORYCAEUS VENUSTUS Dana 



Corycaeus Venustus Dana, Wilkes Expedition, Crustacea, vol. 14, p. 1222, 

 pi 86, fig. 4a, 1853. — Giesbrecht, Fauna und Flora des Golfes von Neapel, 

 vol. 19, p. 674, pi. 51, figs. 32-34, 47, 1892. 



Occurrence. — Found in small numbers at Stations B, C, E, and F 

 in surface and vertical nets during autumn and winter ; also in sur- 

 face and bottom nets on the 100-fathom line in the outside ocean.
