only ;i singrle socket, consists of two, with in two cases a more or less developed third; of 
the outer columns six contain three sockets, two four, and two two. 
Two cirri are preserved, one whole and one with a broken tip. These are 55 mm. lon^ 
and consist of 29 segments of which the 
first is very sliort, the second about twice 
as broad as lon^', tht' third slij^htly longer 
than broad, tiie fourth about twice as 
long as the diameter of the distal cut], 
the fifth nearly or quite three times as

longer than the fifth ; the following seg- 
ments decrease almost imperceptibly in 
length so that the nineteenth and fol- 
lowing are about twice as broad as long;

length so that the last preserved is five or si.\ times as long as broad ; from the third onward 
the segments in lateral view are gently concave both dorsally and ventrally, so that the arti- 
culations are prominent, but this decreases and disappears in the relatively short distal segments. 
The cirri are moderately compressed laterally throughout their entire length, and resemble 
those of the species of P entanietrocrinus and Thatintatocrinus. 
The post-radial series resemble those of Ps. vtira ; the distance from the radial to the 
first syzygy is 8.0 mm. 
The "Investigator" dredged this species at .Stat. 115 in the Andaman Sea (i 1° 31' 40" N., 
92°46'o6"E) in 338 — 396 Metres, on green mud; the bottom temperature was 13^.3 C.

The specimen from .Stat. 45 has the centrodorsal relatively slightly longer than that 
of the type specimen, though it agrees exactly in all other particulars; it is 4.0 mm. in diameter 
at the base and 4.25 mm. from the apex to the interradial border. 
Pj is 10 mm. long, composed of 22 segments, at first short, becoming about as long 
as broad on the eighth, and twice or three times as long as broad terminally; the short 
earlier segments have their corners cut away as in Heliotnetra glacialis\ the pinnule is .slender,
