Report on the Sponges. 
Very few sponges were obtained, and no list of them has been 
drawn up. 
Report on the Diatomaces. 
Tuoven not strictly within the compass of a dredging list the 
following record of the Diatomacez, which were collected, may 
add to the interest and the completeness of the report. Mr. D. 
O. Brown preserved portions of any material likely to yield 
specimens of this tribe of organisms, and subsequently made 
mountings of them for microscopic examination. 
The determination of the species was kindly undertaken by Mr. 
Fred. Kitton, of Norwich, who has furnished the subjoined list. 
Pinnularia distans, Smith’s Synopsis. — 
Orthosira marina, Smith’s Synopsis. 
Pleurosigma marinum, Donkin.
