RHINCALANUS NASUTUS Giesbrccht 



RMncalanus nasutus Giesbbecht, Fauna und Flora des Golfes von Neapel, vol, 

 19, p. 154, pi. 3, fig. 6 ; pi. 9, figs. 6, 14 ; pi. 12, figs. &-12, 14, 16, 17 ; pi. 35, 

 figs. 46, 47, 49, 1892.— G. O. Sabs. Crustacea of Norway, vol. 4, p. 15, pis. 6, 

 7, 1901. 



Occurrence. — A few females were taken in the bottom net at the 

 100-fathom line outside the bay. 



Remarks. — This is a distinctive pelagic copepod and is not likely to 

 be found within the bay. Farran ^ said of this species : "As far as 

 concerns its distribution in the greater part of the Atlantic, it may 

 be regarded as an inhabitant of the Atlantic current, its distribution 

 to the north and east depending on the varying strength of that 

 stream." 



TEMORA DISCAUDATA Giesbrecht 



Temora discaudata Giesbbecht, Atti Accademei Lincei, Rome, ser. 4, vol. 5, p. 

 814, 1889; Fauna und Flora des Golfes von Neapel, vol. 19, p. 328, pi. 17, 

 figs. 3, 20, 23 ; pi. 38, figs. 24, 25, 28 ; 1892. 



Occurrence. — A few specimens were obtained in the surface net at 

 Station C, October 20, 1920, and in the bottom net at Station F on 

 October 21. At neither place did the catch include a sufficient num- 

 ber to be worthy of a percentage mark. 



Remarks. — This species has not been hitherto reported from the 

 North Atlantic, but is easily recognized by the sharp projections at 

 the posterior corners of the fourth thoracic segment, the asymmetri- 

 cal furca of the female, and the peculiar fifth legs of the male. It 

 did not occur in sufficient abundance to become of any economic im- 

 portance as a constituent of the plankton. 



TEMORA LONGICORNIS (Muller) 



Cyclops longicornis O. F. Mxjllek, Entomostraca seu insecta testacea, p. 115, 



1792. 

 Temora longicornis G. O. Sars, Crustacea of Norway, vol. 4, p. 97, pis. 65, 66, 



1902. 



Occurrence. — Taken in small numbers in bottom and vertical nets 

 at Stations E, F, and G at the mouth of the bay, and in the vertical 

 net at Station Y. It was also present at the surface in the outside 

 ocean. 



Remarks. — Williams found this species all through the year in 

 Narragansett Bay, but Fish listed it as one of the three typical 

 winter forms at Woods Hole. It apparently occurs only in winter 

 in Chesapeake Bay and even then in small numbers. Its presence at 

 both ends of the bay indicates that it may be found at times any- 

 where in the bay.
