Heteromysis formosa, Staith. 
Described by Professor Smith for the United States. I 
noticed this species in some tow-net material collected to 
the east of Inchkeith during October last year. Dr A. M. 
Norman informs me that he procured two specimens of this 
species at Guernsey in 1856, and that he knows of no other 
British habitat for it than the two now recorded. This 
species comes very near Heteromysis (Chiromysis) microps, 
GuOosars: 
COPEPODA. 
Cymbasoma rigidum, J. C. Thompson. 
I observed two specimens of this among tow-net material 
collected to the east of Inchkeith. Both of them, Mr 
Thompson tells me, were females. Unfortunately he found 
it necessary to dissect them, so that I have only the dis- 
sected parts to exhibit. Mr Thompson has the following 
records of its distribution, viz.: the Canary Islands, the 
Mediterranean, Jersey (Channel Islands), Lamlash Bay, 
Arran, Clyde, and Loch Linnhe. It does not appear to have 
been previously noticed on the east coast of Scotland.
