and is sub-cylindric in section, the palmar trocheal depression is 
shallow, and not so elongate, the diameter of the cuneiform and 
magnum facets are narrower relatively to the length of the ulnar 
trochlea ; and the carpal trochlear projection dividing the articulating 
surfaces of the scapho-lunare and magnum is more oblique. These 
differences I believe to be of specific, and not of generic value; never- 
theless I refer it to Pelicanus with a note of interrogation. Appended 
are measurements of the fossils and of the distal end of the ulna of 
Pelicanus mitratus :-—

There are a few other portions of avian bones still unnoticed, 
but I cannot determine their affinities satisfactorily. Although the 
remains of birds are few, when compared with the abundance of 
those of other classes of vertebrata found in these deposits, yet 
the following list of the species already determined, or noticed, 
will show that the class was well represented among the fauna 
whose bones have been preserved in the Siwalik rocks :— 
Struthio asiaticus, A. M.-Edw. Megaloscelornis Sivalensis, Lyd. 
Dromeus Sivalensis, Lyd. Pelicanus Cautleyi, Dav. 
Sp. indet., Brit. Mus. Coll. ? Sivalensis, Day.

IV.—Tue Surrosep Orp Rep SanpsTone oF THE CURLEW AND 
Fintona Disrricts, ConnavuGuT AND ULsTER, IRELAND. 
By G. H. Kinanan, M.R.L.A,, 
President of the Royal Geological Society, Ireland. 
INCE my former paper on the rocks of the Curlew and Fintona 
districts was published,! I have had an opportunity of more 
carefully examining these districts. Both are eminently favourable 
for the theoretical geologist, as in them the rocks are much obscured 
by drift ; however, for a careful and painstaking explorer, there are 
sufficient sections exposed, to show the geological age of the rocks. 
The accompanying diagram represents the rocks as they occur in the 
Curlew Mountains district.
