cooked by mistake, and served up at table with a curlew and other 

 vulgar denizens of the shore. 



The visits of the spotted redshank to our shores may not be of 

 such rare occurrence as is generally supposed, as from its similarity to 

 the common redshank it may possibly be overlooked ; for, unless seen on 

 the wing together, the two species are not easily distinguished from 

 each other ; but whenever seen on the wing, the total absence of the 

 broad white band, which is so conspicuous on the secondaries of the 

 wing of the common redshank when in flight, will always serve as an 

 unerring mark to distinguish the species. 



During the severe frost in January I was told that a Wild Swan 

 was observed for some days to frequent the river near Belleek, but 

 I did not meet it until the 18th, when I saw it flying towards the 

 Moyview shore, and alighting in the river where it was clear of 

 ice, about one hundred yards from where I was standing. It evi- 

 dently wished to come ashore, but could not pass the immense sheets 

 of ice that lay along the shore. It then swam down the river look- 

 ing for some opening in the ice to get to shallow water to feed. In 

 consequence of the thick fog at the time I was unable to keep it 

 within sight, although I was very anxious to get a shot at it. I 

 could not be certain of its species, but am inclined to consider it 

 Bewickii, for this reason, that when it pitched on the water it swam 

 about with its neck stretched out, uttering low calls, something like 

 the words hong, haw, in a low, sweet tone. Yarrell says the call of 

 the Cygnus Bewickii is similar to the words hong, haw, haw, long drawn 

 out ; so it is very probable that the bird in question was of this 

 species. 



A paper was then read entitled :— 



On New Forms of Diatomace^, from Dredgings off the Arran 

 Islands, County Galway. Second Series. By the B,ev. Eugene 

 O'Meara, A.M. 



In my first communication on this subject I ventured to express my 

 opinion, that a more careful examination of the material would lead to 

 the discovery of other new and interesting forms ; and I have now 

 the gratification to inform you that my anticipations have been fully 

 verified. I have been engaged from time to time, as opportunity was 

 afforded, in examining the material with most satisfactory results. 

 Some few of the forms recently discovered I shall submit to your 

 notice. 



Coscinodiscus fasciculatus. — Fig. 1. x 600. N. sp., O'M. Diameter 

 •0033.; valve areolate; the areolae in parallel fasciculi about sixteen 

 in number; each fasciculus contains nine parallel moniliform lines; 

 the central lines reach from the centre to the circumference; the 

 next lines on either side of the same length, each successive pair 

 terminating at a greater distance from the centre.
