No doubt this species is nearly related to the South American 
Cucumaria leonina Semper, to which it was referred hy Den dy, 
who regards it, at most, as a variety of this species. There can, 
however, in my opinion, he no question hut that the New Zealand 
form is a perfectly distinet species, which I shall designate as Cuc. 
leoninoides, this name hinting hoth at its history and its affinity 
with the South American species. Otherwise, it hears also distinet 
relations to the Kerguelen form, Cuc. lævigata (Verrill), from which 
it dilfers, however, conspieuously in not heing hrood-protecting. 
A detailed description is given hy Den dy and thus need not 
he given here again; it may suffice to point out the characters 
which distinguish this species from C. leonina.^) 
The calcareous deposits are of the type characteristic of C. 
leonina and related species, and are arranged in the same way: 
the serrate end of the plates overlapping and making the skin just 
a little hit rough or, as seen in the microscope on cleared up pieces 
of skin, even finely spinous. However, they are well distinguished 
from those of leonina, heing considerahly hroader and with a larger 
numher of holes outside the four primary ones (Fig. 27.a to com- 
1) Den dy expresses, with full right, I think, serious doubts as to the 
correetness of regarding S e m p e r’s Cucumaria dubiosa and Cuc. leonina 
as one and the same species, as is done by Ludwig, Lampert and 
Perri er. This question does not, however, concern us here direetly. 
The name chosen for the Auckland Isl. species will be appropriate, even 
in case it is ultimately proved that the two said species are not identical 
and that the South American species should be named Cucumaria dubi¬ 
osa Semper, the relation to the true leonina being equally close.
