This species was not taken by myself, but two specimens taken 
at Mokohinau were presented to me by Captain Bol lo ns. This 
appears to be the only New Zealand locality, from which lt is 
known with certainty. (Comp. also Ben ham, loc. cit.). Evidently 
the species is, at any rate, not comrnon at the New Zealand coasts. 
It is not known with certainty to occur outside the Austrahan and 
New Zealand seas. * 1 ) 
l ) In my „Studies of the development and larval forms of Echinoderms 
I have ’described the larva of Heliocidaris tuberculata , reared from 
specimens found at Misaki, Japan. This is in contradiction with the above 
statement of the occurrence of the species in the Southern Seas only, 
and needs an explanation. 
During my stay at Misaki I had no access to literature, except to 
Tokunaga’s work on the Japanese Echinidæ. In this work (in Japan- 
ese) the species so comrnon on the shores at Misaki is recorded as 
Strongylocentrotus tuberculatus. I adopted this (specific) name, having 
got it wrongly into my mind that I had myself (in my „Ingolf“-Echin- 
oidea) shown the Japanese form to be the true tuberculatus - while, 
in faet, I had given the proof that the Japanese form was really quite 
different from the true tuberculatus from the South sea and should be 
referred to a different genus, Anthocidaris. So completely had that idea got 
into my mind that I did not at all think of looking up the matter when
