broad as long, the second somewhat longer than broad, the thh-d two and one half times as long 
as the proximal diameter, and the following three times as long as the proximal diameter; 
the third and following have prominently expanded and overlapping distal ends which are 
especially prominent on the distal side of the pinnule where they are armed with long and 
prominent spines. P„ is about half as long as P^, with 7 segments which are very long with 
very strongly everted spinous distal ends, especially on the distal side ; a large genital gland 
runs from the base of the third to the base of the sixth segment. Similar genital glands occur 
on the following pinnules to and including P.. 
The large specimen from Stat. 99 resembles that from Stat. 289. 
The individual from Stat. 105 has 10 cirrus segments. 
The two from -Stat. 125 resemble those described from .Stat. 50 ; the arms are 25 mm. 
long; the cirri are 4.5 mm. long with 9 segments; there is no genital gland on P,. 
The example from Stat. 289 is large, with the arms 30 mm. long; the cirri are 6 mm. 
long, composed of 10 segments; Pj is from 4 mm. to 4.5 mm. long, with 10 — 12 segments; 
there is no oenital grland on P„. 
The specimen from Fianda is even larger, with the arms 35 mm. long; there are 
10 cirrus segments.

The centrodorsal is very low hemispherical, the bare polar area almost covered with 
pits representing obsolete cirrus sockets. 
The cirri are XXX, 10 — 12, 8 mm. to 9 mm. long, the outer portion strongly recurved; 
the first segment is very short, the second about twice as long as the median diameter, the 
third about three times as long as the median diameter, the fourth about as long as the 
third ; the following gradually decrease in length so that the antepenultimate is sligtly longer 
than broad, and the penultimate about as long as broad ; the second and third are strongly 
constricted centrally with expanded ends ; the following gradually lose this character and become 
laterally flattened and hence broader in lateral view, the outer .segments being nearly or quite
