tion obtained from the Japan Sea. From it mine differs chiefly in 
numerical proportions—(a) size, (b) number of adambulacral spines, 
(c) number of oral spines, (d) number of spines on the abactinal plates, 
(e) number of marginals, &c. Several other species have since been 
described, from the eastern shores of the Pacific, but I am unable to 
make any comparisons with them.

Specimens were obtained at several stations. It is by far the 
commonest of the littoral starfishes on, at any rate, the South 
Island, and Mr. Farquhar has published some interesting notes on 
it [15]. 
Localities.—Coast of Otago [and generally round the South Island, 
and Wellington]. 
Stichaster polyplax Muller and Troschel.

A single small specimen was collected, but was without indication 
of station when it reached me. It is fairly common on the shores of 
both Islands, having been recorded from Auckland, Wellington, 
Nelson, Sumner, Otago, as well as from the Chatham Islands.

Stations 24, 29. 
Two bright-red starfishes, which I refer to this species, differ 
slightly from one another and from the account of the species given 
by Farquhar in 1895. 
In the first place they are considerably larger. One of them, with 
six arms, has R. 88, r. 12mm.; r.: R. = 1: 6°33, with the greatest 
width of arm 18 mm., which is at a short distance from the base. 
I cannot detect any definite madreporite, though at two spots the 
abactinal plates are crowded. 
The other, with five arms, one of which has evidently been regene- 
rated, measures R. 71, r. 7mm.; so that r.:R. = 1: 10714. This 
one shows the characteristic four madreporites, though the spines 
on the abactinal surface are less numerous than in typical specimens 
in this Museum. In the larger specimen the arrangement of plates 
and spines agrees with these individuals which I received from Mr. 
Farquhar. 
The greater size of the specimens may be related to the greater 
depth at which they were obtained.
