from the decembrachiate juvenile stage to the multibrachiate adult 
condition. Three IIBr series, all 4 (3 — 4), are present, whereas 
the single previously known specimen had but one IIBr series. 
The cirri are 13 mm. long, and the thirteen arms 75 mm., while 
in the type the measurements are 20 mm. and 180 mm. respectively. 
In general appearance the two specimens are the same; there is 
the same overlapping of the brachials and roughness of the dorsai 
surface of the arms, and the proportions of the proximal pinnules 
and of their component joints is similar, though in this specimen 
the joints of the pinnules in the proximal third of the arm have 
rather more prominent distal ends, and the lower joints of the 
first three or four pinnules are rather more strongly carinate. The 
cirri have the characteristic somewhat sharp expansion at the 
articulations, and, consequently, the same knobby appearance as 
those of the type, but the component joints are slightly shorter, 
none of them being quite so long as broad; the opposing spine, 
though well marked as in the type, is characteristically small. 
The cirri are nineteen in number, arranged, as in the type, in 
one and a partial second crowded and irregular row. 
Of the three IIBr series present, two are nearly full size 
while the third is as yet very small, showing that the adolescent 
autotomy had taken place not long before capture. 
Another rather small example with twelve arms about 45 mm. 
long and twenty cirri 12 mm. long was taken at this locality. 
The centro-dorsal is thin and discoidal, the broad bare polar area 
4 mm. in diameter, and slightly concave; the cirri are arranged 
in a single marginal row.

this locality resemble those of the preceding.
