outer wall of the latter has been removed to a new posi- 
tion, as may be seen on the plan (fig. 3), so as to increase 
the room to about three times its original size. The room 
now measures about 18 feet in length by 20 feet from 
window to door. It is at present larger than-is necessary 
for the accommodation of our small working library of 
Marine Biological and Fisheries publications, but will no

workers in the future. We are very grateful to those 
who kindly provided the funds that made this new 
laboratory wing possible (see Hon. Treasurer’s Statement 
at the conclusion of this Report). 
Some OTuer INVESTIGATIONS. 
Mr. William Riddell, in addition to assisting me in 
my Plankton investigation, has been collecting and 
identifying the Polychaet Annelids of the neighbour- 
hood, and he reports to me on his work as follows :— 
‘““T am able to add twenty-eight species of Polychaeta 
to the previous records for Port Erin, sixteen being 
apparently new to the L.M.B.C. district. Four of these 
had been identified by Mr. Chadwick but not recorded, 
and three of these I only know from his specimens. I am 
able to confirm the previous records of Sthenelais 
zetlandica, which Hornell has doubted, as I have found 
a mounted parapodium, from the original specimen, in 
the Zoological Department of the University of Liverpool. 
At the same time I am inclined to doubt one or two of 
Hornell’s records, notably Scolelepis (Nerine) vulgaris 
Johnst., which I think should be S. fuliginosa Cpde. At
