RECENT OSTRACODA OF BELFAST LOUGH. 
By SAMUEL M. MALCOMSON, M.D. 
« S very few Ostracoda have been recorded from the North of Ireland, and 
as no systematic list of the species inhabiting Belfast Lough and its 
neighbourhood has ever been made out, I determined some years ago to 
examine all the material containing them which I could obtain, with a view to 
supplying this deficiency. 
When I mentioned my project to Mr. Joseph Wright, F.G.S., he very 
kindly offered to place at my disposal all the material dredged by himself and 
Mr. Wm. Swanston, F.G.S., from the examination of which he had compiled 
the extensive list of Foraminifera published in an appendix to the proceedings 
of the Belfast Naturalists’ Field Club for 1876-77. To these valuable dredg- 
ings I have added one gathering of my own, consisting of shore sand from 
Rockport, County Down, and also the dredgings taken at the Field Club excur- 
sion in the steam tug “ Protector,” in 1885. 
Want of time has prevented the examination of Mr. W right’s entire series 
of dredgings, but those already done seem to give a fairly representative list of 
the Belfast Lough species, and as Strangford Lough has not yet been systema- 
tically dredged, I have considered it better not to incorporate the gatherings 
from that locality in the present list. 
Altogether, gatherings from twenty- one stations have been examined. 
Eleven of these situated in the Irish Channel, just outside the mouth of Belfast 
Lough, were all, except three, in moderately deep water (30 to 72 fathoms). 
Five of the stations were in Belfast Lough itself, and all in shallow water 
(4 to 10 fathoms), while the remaining five stations were situated on the beach, 
and consisted of shore gatherings, taken from the surface of the sand or from 
rocky pools between tide marks. 
These gatherings altogether have yielded 100 species of marine Ostracoda,
