Faunistic and Other Special Investigations. 



During the year a good deal of collecting has been done 

 on the shores of the south end of the Isle of Man, and 

 the Laboratory Assistant has made many gatherings of 

 Copepoda from the sand and mud at low tide, and has 

 sent them to Mr. Thompson. The tow-net has also 

 occasionally been attached to the buoy at the entrance to 

 Port Erin bay, and left out all night. One such gather- 

 ing taken in November was sent to Mr. A. 0. Walker, 

 and he reDorts to me that it contained : — 



E 



Siriella armata (M. Edw.), several young. 

 Cuma scorpioides (Mont.), one only. 

 Iphinoe trispinosa (Goodsir), one only. 

 Bathyporeia pelagica, Bate, one only. 

 Aphcrusn bispinosa (Bate).
