than in the type is due simply to its bad State of preservation, 
the spines normally covering the radial shields having dropped of¥.

Not having seen any specimens of this Ophiurid, known only 
through H. L. Clark’s description of the unique specimen found 
by Mr. Farquhar under a stone near low water mark off Welling- 
ton, I can only offer a few critical remarks to the said description. 
H. L. Clark includes this form among the Ophiacanthidæ, as 
an extreme development from an Ophioconis-WkQ ancestor, though 
recognizing the uncertainty of its real relationships, stating that 
“it is quite possible that its true position is in the Ophiodermat- 
idæ“. — Judging from the figures given by Clark one cannot 
help thinking the latter suggestion by far the more probable; in 
faet, were it not for the grains covering the base of the arms, I 
would suggest it to be a young Pectinura. But, as jusily said by 
Clark, “mueh more abundant material is necessary before the 
matter can be satisfactorily determined. “ I would only point out 
this case as exemplifying in quite a special degree the insufficiency 
of photographic figures. I defy anybody to find in the figures, 
given by Clark, the details of the armplates or the mouth structure. 
We gather from these figures that it is an Ophiurid with very 
short, robust arms, with short, appressed armspines, the disk being 
covered with grains. But this is not satisfactory in an up to date 
work on Ophiurids.

Of this species, hitherto known only from the single specimen 
on which Farquhar based his description, I have been fortunate 
enough to find three specimens in the following localities:
