SOUTH DONEGAL, 1880.

'pj^j’HE objects contemplated by the Club in visiting the Southern Coast of 
( dJXv^ ) County Donegal embraced several departments of Natural Science, 
'U® especially botany and geology, and as the time was limited it was im- 
possible to devote much attention to dredging. Three shore gatherings, and 
four hauls of the dredge were, however, secured, and the present list is the 
result of an examination of material thus obtained. This list is not given 
as exhaustive of the locality visited, but simply as a contribution to 
our knowledge of the Irish rhizopodal fauna. It will also serve to indicate 
that rich results are likely to reward more systematic investigations in 
this quarter. Of the shore gatherings, that from Muckros was the only one 
which yielded a good supply of Microzoa. It was collected in a small sandy 
bay adjoining the singularly wild and remarkable precipices of Muckros Head. 
As is usual in the sandy bays open to the Atlantic, along our Western Coast 
Truncatulina lobatula greatly preponderated over all other forms. Haplo- 
phragmium globigeriniforme, Lagena costata, and Polymorphina myristiformis 
were large and abundant at Muckros, and also in the dredgings taken in the 
open sea, off the headlands of Slieve League, whilst the same forms were rare, 
and in poor condition in the more sheltered waters of Killybegs Harbour. The 
four dredgings from Killybegs and Slieve League might, with little disadvan- 
tage, have been recorded as from two stations. For example, the two gather- 
ings from Killybegs, one taken in seven fathoms water, inside the harbour, 
the other in seventeen fathoms, a few hundred yards outside the Lighthouse, 
were very similar, both in nature of bottom and foraminiferous yield. The 
material dredged at both places was soft turfy ooze, yielding Microzoa in great 
profusion, and differing merely in that the one gathered outside the Light-
