d- 50^71 cirrus segments 
e^ ossicles of the IBr series and first two brachials without spines 
on the dorsal surface or on the proximal or distal borders, smooth 
dorsally, or with a few low inconspicuous tubercles, usually with 
slightly spinous lateral borders; third and following brachials 
with the dorsal surface studded with very fine short spines or 
sharp tubercles; cirri XX, 62 — 71, very slender, 50 mm. long; 
10 — 13 very slender arms 80 mm. to 90 mm. long; IIBr 
4(3 + 4) (south of Kurrachi, India; 1377 Metres) . . 
e" ossicles of the division series and the first two brachials with 
very prominent spines on the proximal and distal borders and, 
to a greater or lesser e.xtent, on the dorsal surface 
f^ spines on the borders of the ossicles of the division series 
few, large and coarse, those along the proximal edges of the 
axillaries especially long, and slightly curved dorsalward ; no 
spines on the dorsal surface of these segments except for a 
few in the centre of the IBrj and first brachial, and a line 
of short spines or tubercles down the centre of the axillaries; 
outer portion of the arms compressed laterally, the central 
portion of the distal border of each brachial abruptly produced 
into a broad dorsoventrally flattened overlapping spine; cirri 
XX, 50 — 55, 32 mm. long; 10 — 12 arms i 10 mm. long; 
IIBr 4 (3 + 4) (Hawaiian Islands; 632 .Metres) . . 
f" spines on the borders of the ossicles of the division series 
and first two brachials finer and much more numerous ; the 
central portion of the distal edge of the outer brachials is 
not abruptly produced 
g^ a few coarse spines on the dorsal surface of the ossicles 
of the IBr series and. first two brachials; these segments 
have the proximal and distal edges everted and abundantly 
armed with very fine spines, and a more coarsely spinous 
median carination 
h^ larger and stouter, with more numerous cirrus segments 
arms 100 mm. long; cirri XV — XX\'\ 54 — 66, 30 mm 
to 50 mm. long (Philippine Islands to Timor 
211—883 Metres) 
h- smaller and more slender, with fewer cirrus .segments 
arms 80 mm. long; cirri XXY, 50 — 55, 30 mm. long 
(sou th wester n Japan; 792 Metres), 
g- numerous spines evenly distributed over the dorsal surface 
of the ossicles of the IBr series and the first two brachials.
