smooth calcareous bodies (Fig. 55,b) occur, lying mainly parallel to 
the muscle fibres. No other calcareous bodies in the skin. The 
tentacles contain numerous small arched spicules, slightly widened

in the ends (Fig. 55.a); they are arranged in a close series along 
each side of the tentacle and its digits. 
The tentacles are twelwe in number, with 5 — 6 pairs of digits, 
the dista^l ones being the longer, though not very conspicuously 
longer than the proximal ones. The calcareous ring is composed of 
twelwe pieces, there being two interradial pieces in the two dorso- 
lateral interradii. The radial pieces are perforated (Fig. 56.a). Oeso- 
phagus rather long, without any muscular thickening. The intestine 
very sinuate, with a large loop. Its course otherwise not to be 
made out exactly. 8 Polian vesicles and one stone canal. The 
gonads long, unbranched tubes. The type specimen, the only one 
with the genital organs preserved, being a male, it is evident that 
the species has separate sexes. Ciliated funnels (Fig. 55.c), all 
small ( 0.1 mm), with a wide opening, in the left dorso-lateral and 
the left ventro-lateral interradii. 
In his report on the Echinoderms of the N. Z. G. Trawling 
Expedition Ben ham records Ch. 
gigas Dendy & Hindle also from 
Stewart Island. Having received a 
pair of these specimens (collected 
by Dr. G. M. Thomson) from Prof. 
Ben ham I must declare them to 
be identical with Ch. nigra, not with 
Ch. gigas. Benham himself also 
appears to be in doubt about the 
correctness of identifying these spe¬ 
cimens with Ch. gigas. — Judging
