Stephanetrochus oldhami, Alcock. 
Four examples were obtained and although exhibiting 
inter se a considerable range of variation, they appear to fall 
into line with other specimens in the Indian Museum, previousl 
obtained by the R.I.M.S. ‘‘Investigator’’ and described by 
Alcock (1898, p. 19), under the above name. 
Flabellum pavoninum, Lesson. 
A single specimen was obtained and was referred to this 
place of a ‘‘ sessile scar of attachment.’’ Its occurrence serves 
to justify Prof. Stanley Gardiner’s (1904, p. 123) opinion that 
F. pavoninum and F. paripavoninum are, in reality, repre- 
sentatives of the same species. 
Flabellum japonicum, Moseley. 
Thirty representatives of the species were obtained, show- 
ing considerable range of variation both in the condition of the 
columella, as described by Alcock (loc. cit., p. 23), and in the 
form of the septa which varied from perfectly straight plates to 
a markedly crinkled condition, closely resembling that found 
in F. laciniatum. : 
A single example of Cerianthus, sp., was also obtained. — 
Po azta.—Numerous worms belonging to the family 
Maldanidae were obtained together with the tubes in which they 
live. 2 
The results of the six-bottom trawls that were made 
during the survey season 1911-12 are, so far as they have 
been worked out at the present date, given below :— 
Station 392. eee 
a ad at -  Depth—400 fathoms. 
On this occasion three or four sharks about 4 feet in length 
came up with the trawl. Unfortunately while the trawl was 
being brought alongside, two or three of the contained — 
one apparently an example of Coloconger, floated out through the 
mouth, and, although an attempt was made to recover them 
by lowering a boat, the sharks had already made use of their 
opportunity and they were lost irretrievably.
