quite typical. The exquisite and characteristic pinkish coloration of 
spines and tubercles is accordingly no reliable specific character. 
Two specimens of this species were dredged in Paterson I nlet, 
Stewart Isl., in 10 — 30 meters 17 /xi 1914. Further several spec¬ 
imens were given me by Captain Bollons, who had dredged 
them off the East coast of the South Island in depths of ca. 40— 
100 meters. 
The species appears to be confined to the seas off the South 
Island of New Zealand. 
lt seems evident that the species described by H. L. Clark 
in his Report on the Echinoderms of the „Endeavour“ (p. 111, PI. 
XLI, Figs. 1—3) under the name of Parechinus notius is very 
nearly related to Ps. Huttoni, representing an Australian form of 
the genus Pseudechinus. That it has no nearer relation to the ge¬ 
nus Parechinus is evident from the characters of its buccal mem- 
brane (perfectly naked, excepting the buccal plates) and the glob- 
iferous pedicellariæ (carrying a lateral tooth only on one side of 
the blade). That it is distinet from Ps. Huttoni would appear from 
the character of the apical system (all oculars excert), the different 
colour of the test (pale brown) and the shape of the ophicephalous 
pedicellariæ (valves not at all constricted). 
It is of considerable interest that this genus, otherwise known 
only from the New Zealand seas, thus has a representative also in 
the Australian seas (off the S. E. coast).

In some dredgings off the North of New Zealand a few small 
Echinoids were taken which, evidently, represent a new species 
of the genus Pseudechinus. Unfortunately all the specimens are 
immature, so that an adequate description of the species cannot 
be given; but the characters shown by the specimens available 
will, I think, suffice for recognizing the species, so that I have 
thought it justifiable to establish the species, in spite of the insuf¬ 
ficient material.
