When in Galway this summer, Minos was, as usual, in great profu¬ 
sion. It differs materially in its habits from the other native species of 
the genus, concealing its oval, earth-coloured cocoon (of which I have the 
pleasure of exhibiting specimens) among the roots of the herbage, or at¬ 
tached to a stone at the surface of the ground; but from the nature of 
the localities in which alone the insect is found in abundance,—viz., 
fields in which rock was the rule, grass the exception,—the cocoon is ex¬ 
tremely difficult to find. 
Professor J. Reay Greene, Honorary 7, Secretary, read a paper entitled 
“ Notes on the present state of our knowledge of the Coelenterata.” 
Rev. Joseph Greene, M. A., exhibited specimens of the very rare 
DeilepMla galii , in the most beautiful state of preservation, taken near 
Heal; also a hybrid moth, bred from Smerinthus populi and 8. ocellatus . 
Mr. E. Burchell exhibited a box of specimens illustrative of his paper. 
The Rev. Professor Haughton, Y. P., exhibited an unique specimen 
of JSuomphalus cristatus (Phillips), preserved in the Museum of Trinity 
College. 
The Meeting then adjourned to January 15, 1858.

JUNCTION OE THE LIMESTONE, SANDSTONE, AND GRANITE AT OUGHTERARD, 
COUNTY GALWAY. BY JOHN BIRMINGHAM, ESQ. 
In few places in Ireland can the junction of the granite with other 
rocks be seen to greater advantage than immediately about Oughterard. 
At the picturesque waterfall, near the town, a series of three or four 
different sandstones appear overlying the syenitic rock, while they, in 
turn, are overlaid by the beds of carboniferous limestone. At Derry- 
laura, about one mile N.W. from Oughterard, a coarse red conglomerate,
