Wellington Harbonr, 5—10 fms. 16/11. 1915. 1 large specimen 
(posterior half only). I have further received a small specimen from 
Captain Bol Ion s, dredged in Cloudy Bay, 19 fms. Also, I have 
a fragment (anterior end) of a specimen from Akaroa Harbour, 
from Mr. Suter. 
The species being hitherto known only from the type-locality, 
off New Brighton, the new localities given here somewhat extend 
the area of its distribution. There can, however, hardly be any 
doubt that it will prove to have a much wider distribution in New 
Zealand seas. 
To the descriptions given by the authors quoted I would add 
only one point, viz. that the cups of the epidermis produce a very 
characteristic grainy appearance of the scales. When this is not 
seen, as in some specimens from New Brighton Beach in hånd, it 
is due, evidently, to the cups having been rubbed off. 
I perfectly agree with Perri er and Dendy & Hindle in 
rejecting the genus Ludwigia established by Reiffen (Op. cit.) 
for this species. It is perfectly evident that this species is closely 
related to Cucumaria alba, though quite distinet from the latter 
species. Of course, it is highly probably, that, when once a thorough 
revision of the whole genus Cucumaria is undertaken — or rather 
of all the Cucumariidæ — a number of separate genera will have 
to be established, and then also forms like alba and ocnoides will 
be removed from the genus Cucumaria in a restricted sense. But 
such revision will be a very great task, which can only be ac- 
complished by a competent specialist in this group, and not by 
some young student, who gets some little material from his Pro¬ 
fessor with the object of making his doctoral thesis of it. 
For the rest I may call attention to the faet that the name 
Ludwigia is preoceupied for a longicorn beetle (Pie. Matériaux pour 
servir å l’étude des Longicornes. I. 1891, p. 47).
