ferent phylogenetic origin. I cannot enter more nearly on 
this interesting problem on the present occasion. It may only be 
pointed out that the character of the compound ambulacral plates 
of Echinobrissus — which have been shown to be of the Echinoid 
t yp e _ wih be of importance for settling the question, where 
the ancestral form is to be looked for. Also the structure of the 
globiferous pedicellariæ — which recall those of Stomopneustes 
may prove to be of importance in this connection. 
The statement that Echinobrissus recens occurs at Madagascar 
(„Rev. of Echini“, p. 108) doubtless rests on unreliable labelling of 
specimens from older collections. It is not known with certainty 
to occur outside the New Zealand waters. If an Echinobriss /s 
should prove really to occur at Madagascar, it will no doubt turn 
out to be another species.

Numerous specimens, mainly small ones, were dredged o ff Ti ri 
Tiri, Auckland, in a depth of 30 meters. Further I have taken 
three specimens in Queen Charlotte Sound, 6 20 meters, and one, 
somewhat abnormal, specimen in Paterson Inlet, Stewart Isl., in a 
depth of 30 meters.
