The specimen from Stat. 260 has the arms about 100 mm. long and the cirri XIV, 
23 — 25, about 15 mm. long. 
The larger example from .Stat. 305 has the arms about 100 mm. long and the cirri 
XIX, 21 — 25 (usually 22 — 23), 17 mm. long; the fourth is a transition segment; the distal 
intersyzygial interval is three oblique muscular articulations. The other specimen is similar, but 
slightly smaller ; the .single complete cirrus has 20 segments of which the fourth is a tran- 
sition segment. 
All three of these specimens are considerably larger than the two from which the spe- 
cies was originally described, though otherwise resembling them.
