less and less obliquely wedge-shaped distally, and finally oblong and elongate. All the brachials 
are perfectly smooth, with no ornamentation of any kind.' 
Syzygies occur between the third and fourth, ninth and tenth and fourteenth and fifteenth 
brachials, and distall)' at intervals of two oblique muscular articulations. 
Pj is 9 mm. long, very flexible and .slender, composed of 35 — 40 short segments most 
of which are about as long as broad with all the angles cut away and hence appearing 
rounded, those in the terminal third becoming slightly elongated ; the articulations are enlarged, 
and the whole pinnule suggests a string of small beads. P., is 5 mm. long with 12 — 15 segments 
of which the first two are about as long as broad, and the fourth and following rapidly become 
elongated, and very slender distally; the fifth, si.xth and seventh segments bear a large rounded 
genital gland; the following pinnules Lo P^ are similar, but the genital gland gradually moves 
nearer the base of the pinnule, on P^ extending from the third to the sixth segment. The 
distal pinnules are 12 mm. long with 20 segments of which the first is very short, almost 
band-like, the second is almost triangular, the third is about half again as long as broad, the 
fourth is about twice as long as broad, and the remainder become progressively elongated. 
The colour in spirits is yellowish white, with a large black spot on each side of each 
syzygial pair; the inner half of the articular faces of the syzygies is also black. 
The specimen described is Cat. X" 22675 U. S. National Museum.

The centrodorsal is hemispherical or subconical, the polar area finely papillose with a 
rounded tubercle at the apex. 
Cirri XXX- — XL, 17 — 23 (usually 21 — 22), 16 mm. to 18 mm. long; the first two 
segments are short, about twice as broad as long, the third is about twice as long as broad, 
the fourth-eighth or -ninth are greatly elongated, four or five times as long as broad, and the 
following decrease rapidly in length so that the terminal six to eight are about as long as 
broad; the elongate proximal segments are somewhat "dice-box shaped" with swollen arti- 
culations; the shorter distal segments increase gradually in diameter from the proximal to the 
distal ends, the latter slightly overlapping the bases of the succeeding segments; on the distal 
part of the dorsal side of the penultimate segment there is a very small opposing spine which
