7 spines on the basal armjoints; in the middle of the arm there 
are only 5 spines. The long, downwards directed ventral spines 
(Fig. 15.a), may perhaps have relation to the biology of the spec¬ 
ies: mainly living among algæ, not burrowing in sand or mud, as 
is otherwise the rule among Amphiurids. 
Åmph. magellanica was hitherto known to occur only in the 
Magellan region and at the Gough Island in the S. Atlantic. It is 
then of considerable zoogeographical interest to have proved it to 
occur also in the New Zealand region. The greatest depth at which

it has been found is 75 fms (Gough Isl.). It appears to be mainly 
littoral. 
After this had been written I received from Prof. Benham a 
specimen of this species dredged in Otago Harbour, 2 fms, and 
also one from Foveaux Strait. This proves, as might be concluded 
from its occurrence at the Cook Strait coast, that this species oc- 
curs along the coasts of the South Island of New Zealand. Whether 
it extends farther North than the Cook Strait remains to be seen.
