This tolerably distinct species was met with, though somewhat sparingly, in 
gatherings collected at Stations 7, 12, 15, 22, 85, and 86, 26° 23’ N., 20° 20° W., to

1849, Coryczus 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. 
Coryceus longistylis, Dana. 
1849, Corycexus 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.

This Coryceus was observed in gatherings from twenty-five different stations, 
extending from Stations 11, 18, and 15 to 88, 90, and 94, 23° 50’ N., 21° 34’ W., to 
30° 25’ 8., 45° 45’ W. ‘The species was apparently more or less uniformly distributed

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

in which it was met with were those collected at Stations 25, 27, 29, 30, and 31, 
15° 15’ Nu, 25° 09" Wi to Li 0eN,, 25-7 oe
