This specimen from Stat. 310 has the cirri XIX, 14 — 15 (usually the latter), 10 mm. 
long; the first segment is short, the following gradually increasing in length so that the fourth 
and following are about as long as the median diameter; in the longest cirri the fifth-eighth 
may be one third longer than broad basally; the fourth-seventh or -eighth are centrally constricted 
with expanded distal ends, this e.\pansion being especially marked dorsally so that the dorsal 
profile of the cirrus is rather strongly serrate, but this dies away distally so that after the tenth 
segment the dorsal profile becomes smooth and straight; the fifth is a more or less marked 
transition segment. 
The five arms are 55 mm. long. 
P., is composed of 12 — 13 segments, as in the type specimen. 
This example difters from the type of the species only in its slightly greater size. 
The individual from Stat. 49'' has the ornamentation of the brachials slightly more 
accentuated than in the preceding. 
It is possible that this, like the preceding, is merely a very strongly marked variety 
of H. indivistis.

The two specimens from Stat. 65a are small, with arms from 25 mm. to 30 mm. long. 
The four examples from Stats. 144 and 257 are also small; in these the brachials, 
except the basal, show a strong production of the distal edge. 
The individuals from Stat. 260 have the arms 35 mm. and 40 mm. long. 
Of the specimens from Stat. 305 one has the arms 80 mm. long, the cirri X\'III, 17, 
II mm. long, and the second pair of pinnules 6 mm. long with 11 — 12 segments; another 
has the arms 95 mm. long, the cirri XVII, 16, 17, 13 mm. long, and the second pair of 
pinnules 7 mm. long with 12 — 13 segments; the third specimen is similar to the first. 
These agree minutely with specimens from the Philippine Islands, taken by the "Albatross" 
at Stat. 5356 (Cat. X" 35139 U. S. Xat. Mus.).
