All but one of the twenty-six specimens of this robust species are in good condition. Six have arm lengths of between 100 and 130 mm., nine of between 80 and 95 mm., five of between 60 and 75 mm., four of between 40 and 55 mm., and the smallest is 28 mm. long. The largest are, I think, bigger than any of the Swedish Expedition's collection and it is perhaps for that reason that I have to make some of the small additions that follow to Mortensen's full description. The radial may be longer than the costal as in Mor- tensen's figure (1918, pi. ii, fig. i), or of the same length or shorter. The examination of the cirri of the specimens of this collection leads to the following numerical description, wider than Mortensen's, of the cirri: XXI-XLII, 36-76. There is a distinct and sharp change in colour between „. ., . ... ... '^ ^ r'lg. 19.
