geographical point of view the occurrence of the species at the Camp¬ 
bell and Macquarie Islands seems very natural. 
Among the specimens which I received from Captain Bol lo ns 
there is one specimen from off the East Coast of the South Island of 
New Zealand, ca. 40 — 100 meters, which differs rather consptcu- 
ously from all the other specimens and cannot simply be ident- 
ified with them (PI. VI, Fig. 16). It is distinctly higher than the 
other specimens, 19 mm high, by 28 mm h. d. There are 25 
ambulacral plates and 17 interambulacral plates in a series. The 
apical system is 6,5 mm, the peristome 9 mm. The arrangement 
of the tubercles is as in the typical form, 
but they are upon the whole hardly so large 
as there. The most conspicuous difference 
from the typical form is the colour of the 
test which is a uniform reddish-green. Also 
the globiferous pedicellariæ di ffer from those 
of the typical form in the blade of the larger 
form being longer and more siender (PI.VII, 
Fig. 6). The tubefeet contain fairly numer- 
ous bihamate spicules. — This specimen 
shows the remarkable abnormality that Gen¬ 
ital IV (or OcularV?) is divided into two 
plates (Fig. 8).

the test, and in the large globiferous pedicellariæ, it seems to me 
unjustifiable simply to unite this form with the typical form. Pos- 
sibly it represents a distinet species. On the base of the single, 
dried, not very well preserved specimen in hånd, I do, however, 
not venture to establish it as a separate species but shall prefer, 
until more and better material is available, to regard it as a variety 
only of N. novæ-zealandiæ. 
This new species of the genus Notechinus is easily disting- 
uished from N. magellanicus through several characters, especially 
the colour of both test and spines, the mueh smaller size of the 
apical system and the, generally, distinctly larger number of plates 
(as seen by a comparison of the table, given above, with that of
