and are most useful for those studying the geographical distribution 

 of any given species, or of the Mollusca (or other phy Id) generally. 

 In a nursery in Belfast R. Welch discovered two West Indian 

 species of land-shells alive, which are known to exist in some 

 English greenhouses, but which had not hitherto been recorded 

 from Ireland. Some dredging was carried out at the mouth of the 

 River Six-Mile-Water, Co. Antrim, by the three members named, 

 with F. Balfour Browne, and Paludestrina jenkinsi, a small shell 

 usually found in brackish water, was proved to be spreading 

 enormously here since 1 900, as it was also doing in inland waters 

 in England. Further information on this point and on other 

 faunal changes noted here will be brought before the Club at an 

 early date. 



Some attention has been paid to the group of Terrestrial 

 Isopods or Woodlice, of which eight species were recorded (Irish 

 Naturalist ) as having been found in the three divisions of Co. 

 Cork during the Field Club Conference Week in July. N. H. 

 Foster has made some interesting discoveries in Co. Down in the 

 finding of Armadiiiidium pictum, Brandt, which has not hitherto 

 been recorded from the British Islands, and of Trichoniscus 

 pygmaus, Sars, a species new to the Irish fauna. He has also 

 taken at Hillsborough the rare species Trichoniscus roseus, 

 Porcellio dilatatus, and Metoponorthus pruinosus. In the same 

 County D. R. Pack-Beresford found Cylislicus convexus, which had 

 not previously been obtained in Ulster. In Co. Antrim R. Welch 

 discovered Porcellio Icevis (a species new to Ulster), as well as 

 Trichoniscus roseus, Metoponorthus pruinosus, and Cylisticus 

 convexus in a Belfast Nursery. The distribution of Woodlice in 

 Ireland is very imperfectly known, and the Secretary will be glad 

 to receive specimens from various Counties for identification and 

 record. Specimens should be put in a 30 per cent, solution of 

 alcohol, which is sufficient to preserve them for a few weeks 

 pending their examination.
