need only note here that the Roekling eggs ranged in 

 occurrence from January 19th to October 9th, and attained 

 their highest monthly average (80 per haul) in May; 

 while all other fish eggs together ranged from the end of 

 January to the end of July, and the highest monthly 

 average was 106, in April. The greatest haul of Kockling 

 eggs was 301 on May 21st, and of all other fish eggs taken 

 together 445 on April 9th. It must be remembered that 

 these numbers are for Port Erin Bay, and may be greatly 

 exceeded by hauls in the open sea outside. Eggs 

 belonging to as many as eight species of food-fishes 

 occurred in some of the hauls in the open sea during 

 April. 



Further Remarks. 



We have no special occurrences of rare or oceanic 

 forms to record this year ; but we may note the presence 

 of two interesting organisms which have appeared 

 frequently in the plankton from the Lancashire coast 

 (Barrow Channel), and which we figure, from living 

 specimens, as a help to the identification. 



Figures 1 and 2 show an organism which is not 

 uncommon in our local plankton. Seen from above 

 (fig. 1) it is quite circular in outline, and with the excep- 

 tion of the protoplasmic bodies in the centre, it is perfectly 

 transparent, so that the periphery is difficult to make out. 

 The central area inside the outer rim seems curved so as 

 to have a biconvex shape in profile view (fig. 2). It 

 always contains one, frequently two, and rarely three or 

 four, of the circular protoplasmic bodies. This seems to 

 be the organism named by Hensen (who recorded it from 

 the Western Baltic) the " Barbierbeckenstatoblast."
