show the spinelets of the disk arranged in the same way as upon 
the arms, in groups of some 5—8 spinelets. Probably the single 
compact group of spinelets of the type specimen is a result of 
contraction due to poor preservation. 
It appears that H. lukinsii does not grow to any large size. The 
largest of the fairly numerous specimens which I collected measures 
22 mm R; Benham’s largest specimen was 24 mm R. 
This species was referred by B e n h a m to Henricia ornata (Perr.) 
relying on the faet that Filhol (Op. cit.), evidently on the author- 
ity of Perri er himself, records his specimens from the Campbell 
Island under this name. I cannot, however, accept this identifica- 
tion. A direct comparison of these specimens from the Auckland- 
Campbell Islands with specimens of H. ornata from S. Africa, as 
also with the figures of this latter species given by Koehler in 
his Report on the Starfishes of the “Scotia” Expedition leaves, in 
my opinion, no doubt of their specific distinetness.^) Ben ham 
further is inelined to regard the various antarctic species: simplex 
SI., præstans SI., pagenstecheri Studer and hyadesi Perr. as identical 
with H. ornata, relying on the opinions expressed by Bell, Ludwig, 
Leipoldt, Meissner and Koehler. Without entering on a 
discussion of the validity of these various forms I may State that 
I am not at all inelined to regard them all as only one and the 
same species. Not having access to the species described by Sladen 
I sent a specimen of the Auckland form to my friend Dr. H. L. 
Clark, who was just staying at the British Museum with the ob- 
ject of studying the Echinoderm collection there, with the request 
that he would compare it with those species. He kindly informed 
me that the Auckland form is quite unlike any of these species, 
and that he must regard at least præstans and obesa as distinet 
species. That ornata is, in my opinion, a perfeetly distinet species 
I have already stated. Further I have, through the courtesy of 
Professor Joubin and Professor H. Lohmann received specimens 
1) It appears that also Perri er himself has afterwards come to the con- 
viction that the species from Campbell Island is not identical with H. 
ornata. Among the specimens sent me from the Paris Museum there 
is one named Cribrella campbellensis E. Perrier. This is a specimen of 
H. Lukinsii, quite typical, only with one arm bifid. Perri er’s name 
never having been published, not even as a nornen nudum, it cannot 
replace the name lukinsii of Farquhar.
