This specimen, which is much smaller than the type, has about 25 arms which are 
about 70 mm. long; three of the IIBr series are 2, the other three being 4 (3+4); the IIIBr 
series are all 3 (2 -f- 3) e.xcept one following a IIBr 2 series, which is 4 (3 + 4). The centro- 
dorsal, though stellate, has not as yet cjuite sunk to the level of the radials ; it bears a few
