On the specimen from Stat. 40 only a single undeveloped cirrus with 49 segments remains. 
The individual from Banda has arms 130 mm. long, and cirri X (with some rudimentary)^ 
56 — 63, 45 mm. to 50 mm. long. The colour is black, tinged with violet.

The largest specimen from Stat. 80 has the cirri XV, 36 — 39, 18 mm. to 21 mm. long; 
the cirri are slightly more slender than in the type series, with the long proximal segments 
slightly more elongate; the dorsal pole of the centrodorsal is papillose; P^ is 5.5 mm. long 
with 13 segments; P, is 9.5 mm. long with 14 segments; P.. is 8.5 mm. long with 14 segments, 
similar to P, ; P^ is 6.5 mm. long with 11 segments, similar to P^; Pg is 7 mm. long. The 
elongated proximal pinnules are relatively shorter and more recumbent than in the typical form. 
Of the other specimens two have arms 40 mm. and 45 mm. long respectively; the third 
has arms 15 mm. long and cirri IX, 12, 3 mm. long, resembling the cirri of the species of 
Projuetra, the segments being mostly about as long as broad. On most of the arms P^ and 
P^ have not as yet appeared. 
The example from Stat. 310 has the cirri with 39 — 48 segments (one of each), 25 mm. 
to 35 mm. long; the longest cirrus segments are slightly longer than broad; Pj is 8 mm. long 
with 19 segments; P, is 12.5 mm. long with 18 segments; P, is 10.5 mm. long with 14 — 17 
segments; P^ is 9 mm. long with 15 segments; the lower pinnules are rather less stiffened 
than usual in this species, and are slightly recurved; the spines on the distal ends of the 
pinnule segments are shorter and less prominent than is commonly the case; there are no 
synarthrial tubercles. The size is the same as that of specimens of this species at hand from 
the Andaman Islands.
