ZOOLOGY. 



MOLLUSCS. 



Hydrobia Jenkins!, Smith, in South-east Ireland. 



On May 20th last, during an afternoon stroll, I discovered this interesting 

 little mollusc occurring in abundance for a couple of miles along the 

 marshy banks of the River Barrow at New Ross (Counties Wexford and 

 Kilkenny) in company with I^iiniuza tntncatula and Stcccinea elegans. 



The specimens I collected are all smaller and less pointed than usual 

 in Irish and English specimens, but otherwise seem to agree with the 

 type, though Mr. Lionel E. Adams, who has kindly confirmed my identifi- 

 cation of the species, states that he noticed traces of carination on one 

 or two.

The Food of Trout. 



The angler's complaint against the use of the turbine water-wheel 

 may be just or otherwise. There are other matters that might claim his 

 attention, viz., the food of the fish. I have conversed with many anglers, 

 and few of them know more than that a certain artificial fly will kill 

 Trout under favourable atmospheric conditions, and that they readily 

 take worms during a flood. How few consider upon what the fish live 

 during the entire year. I have examined some rivers with works and 

 mills upon them, and have failed to find many shell-fish that are plentiful 

 in adjoining streams not so polluted. In this connection I would point 

 out that in the stomach of a Trout little over one pound weight, I found 

 IQO s\i€i\s, oi LimncBa peregra, our commonest fresh-water snail, and over 

 130 small Pisidiiim fontinale, and P.piisilhitn. Anything that is detrimental 

 to the creatures upon which the fish live must affect them in a cor- 

 responding degree. Would our fishers become naturalists, not specialists, 

 they would enhance their pleasures.

Spring iviigrants at Poyntzpass. 



As might be expected many of the birds were late in appearing this 

 spring; the Chiffchaff was here on March 31st, but from that date till 

 April 15th there was no further token of its presence ; the Willow Wren 

 arrived on April 20th, the Corncrake on April 24th, the Swallow on the 

 same date, the Cuckoo on April 28th, and I saw the first Swift on the 

 following day. None of these birds however were present in any number 

 till May.
