Further I have received from Mr. W. R. B. O 1 i v e r, 2 specimens from 
Cook Strait, 120 fms, collected by Mr. Hazelwood, 13/VIII.1920. 
Like the authors who have previously dealt with the New Zea¬ 
land form of Åmphipholis squamata I do not find it distinguishable 
from typical European specimens. It is a very extraordinary faet that 
this small, viviparous Ophiurid should as the only one have a 
cosmopolitan distribution. A more profound comparative study of 
the whole question, based on rich material from all parts of the 
World, would be very desirable, and might perhaps lead to the di- 
stinguishing of local forms, or subspecies. For the present we must 
regard all as one species. 
It is very interesting to note that one of the New Zealand 
specimens (Plimmerton) is infested with a specimen of the para¬ 
sitic Copepod Cancerilla; also on one of the specimens from Carn¬ 
ley Harbour, 45 fms, this parasite was found. Mr. K. Stephen- 
sen, who has examined these specimens, informs me that they are 
not identical with Cancerilla tubulata Dalyell, the species infesting 
Åmphipholis squamata in the European seas. This is most inter¬ 
esting, showing that the parasite is not so widely distributed as is 
its host, but replaced in the New Zealand seas by a related, but 
quite distinet species. 
Through the present studies the group of the Amphiurids has 
been shown to be very richly represented in New Zealand seas, 
no less than 16 (17) species having now been found there (not 
counting the Ophiaetis species, as this genus, in my opinion, does 
not really belong to the family Amphiuridæ, but rather forms, to- 
gether with Ophiopholis, Ophiopus and a few other forms, a separ¬ 
ate family, Ophiaetidæ). As it is, upon the whole, no easy matter 
to identify Amphiurids, it may be of some practical value to give 
here the following key to these species.
