Singapore. April 16, 1907. One specimen, which may 
be described as follows: centro-dørsal minute, sharply stellate; 
radials trapezoidal, distally about twice as broad as their length; 
IBr, short, oblong, four or five times as. broad as long, in 
apposition in their basal half, but free distally; I Br, (axillary) 
almost triangular, twice as broad as long; IIBr 4 (3 + 4); follow- 
ing division series 2 (1 — 2); starting from the IIBr axillaries, 
the division series form two, trunks, from which the free arms are 
given off on alternate sides, the first. being external; each trunk 
eventually ends in a pair of similar arms; there are four or five 
(usually four) post-radial axillaries. 
About sixty (fifty-eight) arms 125 mm. long; first two brachials 
small and wedge-shaped, next three oblong, about once and one- 
half as broad as long, then becoming triangular, about as long as 
broad, toward the middle of the arm wedge-shaped, about as long 
as broad, and in the terminal portion wedge-shaped and longer 
than broad; joints of the division series, and especially the brachials, 
with very prominent distal ends, giving the animal a characteristic 
rough feeling and appearance, like that of C. novæguineæ. 
Pn very slender, 15 mm. long, with a peculiar abrupt comb 
at its distal end, carrying thirteen large and long curved teeth; 
proximal brachial pinnules exceedingly slender and hair-like, P, 
10 mm.—12 mm. long, P, 81mm. long, P, 5 mm. long, all with 
large short combs similar to that on Pp; following pinnules stouter, 
after P, without terminal combs, about 7 mm. long, distally be- 
coming more slender and increasing in length to 10 mm.; distal 
pinnules with elongated joints having swollen articulations, the 
end of, each joint armed with long coarse spines, the surface thickly 
covered with shorter spines; terminal three or four joints with 
several long recurved spines dorsally; as in the other species of 
the genus, perfectly formed combs appear at intervals on the distal 
pinnules. 
November 27, 1907. One smaller specimen, with about 
eighty arms; eight of the IIBr series are 2, two 4 (3 + 4); other- 
wise this specimen resembles the preceding.
