No specimens were collected by the author, but two specimens 
have been presented to the Copenhagen Museum by Professor 
Ben ham, one from Foveaux Strait, the other from off Otago, 
20—30 fms. These two specimens differ very conspicuously in 
shape, one having R=1.9 r (R—ca. 70 mm)^) the other R=2.2 r 
(R—49 mm); in the latter specimen the arms are also narrower 
and thus much more distinet than in the former, which is more 
pentagonal. Since, however, no other differences appear to exist 
between them, we must accept also the long-armed specimen as 
belonging to this species, though representing, evidently, a rather 
unusual form which may, perhaps, deserve the recognition as a 
distinet variety. This can, however, only be decided through the 
study of an extensive material. 
Aside from this variation in regard to the general shape I have 
nothing to add to the description given by Ben ham (Op. cit.); 
but I think it may be useful to give a pair of figures of the long- 
armed specimen.

This specimen is undoubtedly identical with the form referred 
by Ben ham to Odontaster Giayi (Bell), but, as suggested by 
Koehler in his Report on the Echinoderms of the “Deuxiéme 
Expédition Antaretique Frangaise 1908—10” (p. 236), the Identi¬ 
fication with O. Grayi is not correct. As is pointed out by Ben¬ 
ham (Op. cit.) the New Zealand form agrees in several respects 
better with O. penicillatus (Phil.) than with O. Grayi; this, together 
with the faet that O. Grayi is othervise known to oceur only in 
0 This specimen is so much curved that an exact measurement is impos- 
sible.
