Idya furcata, Centropages hamatus, Anomalocera pater- 
soni, Isias clavypes, Oithona spinifrons, Harpacticus 
chelifer and Harpacticus fulvus. The specimens of the 
last two species are remarkable for their unusually large 
size and their abundance. It has been suggested that as 
the Harpacticide are well known to be foul feeders and to 
act the part of scavengers in clearmg away decaying 
matters from our shores, they may have possibly been 
attracted in numbers to the tow-net by mistaking the 
electric light for the phosphorescent glow of decomposing 
animal matters. 
Apart from the considerable number of rare species — 
added to our lists by this expedition, the ‘“‘ Hywna’”’ cruise 
of May, 1888, will stand out as a notable occasion on 
account of the successful application of the electric light 
to marine biology, as a bait or attraction in the tow-net 
worked after dark. The obvious extension of this 
illumination method to deep-water tow-netting and trawl- 
ing during the day-time we hope, thanks to the kindness 
of the Salvage Association, to be able to experiment upon 
in a future expedition. 
The committee have decided that so much new material 
has been collected during this last year, and so many supple- 
mentary reports have either been prepared or are now in 
course Of preparation, that they are justified in proposing 
to issue the second volume of the Fauna of Liverpool 
Bay during the present winter. Mr. 8. Nowell, who 
gained some familiarity with the fauna at Puffin Island 
during August, is at present occupied, along with some 
other gentlemen, in the zoological laboratory of the 
college, in examining the various store bottles from 
Puffin Island and elsewhere, recording their contents, 
and sorting out the various groups of animals to be sent 
to specialists for further examination. When these
