This tolerably distinct species was met with, though somewhat sparingly, in 

 gatherings collected at Stations 7, 12, L5, 22, 85, and 86, 26 23' N., 20 20' W., to 

 24 26' S., 40 25' \V. 



Coryczeus rostratus, Glaus. 

 1863, Corycxus rostratus, Claus, op. cit., p. 480. 



The only gatherings in which this Coryc&us was obtained were collected at Station 

 26, 14 33' N., 25 !)' W., and Station 95, 32 15' S., 47 30' W., the one in the North, 

 and the other in the South Atlantic. 



Cor yc feus speciosus, Dana. 



1849, Corycxus speciosus, Dana, Proc. Amer. Acad., Boston, vol. ii. pp. 8-61. 



This fine species was of frequent occurrence in the Scotia's tow-net collections ; the 

 remarkably divergent caudal rami made it easily recognised. It was observed in 

 gatherings from thirty-six different stations, ranging from Stations 7 and 12 in the 

 North Atlantic to Stations 93 and 95 in the South, 26 23' N., 20 20' W., to 32 15' S., 

 47 30' W. 



Corycfcus longistylis, Dana. 



1849, Corycxus longistylis, Dana, op. cit., vol. ii. pp. 8-61. 



This species occurred sparingly in gatherings from Stations 7, 11, 12, 13, and 14, 

 26 23' N., 20 20' W., to 21 28' N., 22 40' W. 



Coryc&us carinatus, Giesbrecht. 

 1891, Corycxus carinatus, Giesb., op. cit. (4), vol. vii. p. 481. 



This Corycieus was observed in gatherings from twenty-five different stations, 

 extending from Stations 11, 13, and 15 to 88, 90, and 94, 23 50' N., 21 34' W., to 

 30 25' S., 45 45' W. The species was apparently more or less uniformly distributed 

 throughout the area traversed by the Scotia between the limits stated. 



Corycseus longicaudis, Dana. 

 1849, Corijcxus longicaudis, Dana, op. cit., vol. ii. pp. 8-61. 



The distribution of this species appeared to be somewhat limited ; the only gatherings 

 in which it was met with were those collected at Stations 25, 27, 29, 30, and 31, 

 15 15' N., 25 09' W., to 11 10' N., 25 20' \V. 



Corycieus clongatus, Claus. 



1863, Corycxus elongatus, Claus, Diefreilelemlen Copepoden, p. 157, pi. xxiv. figs. 3 and 4.
