44 The Irish Naiuralist. February, 



Haplopthalmus danlcus, Eudde-Lund. 

 Rather coininon in a fern-honse, and more sparingly in the open, 

 lioth species of this genus are much slower and more deliberate in their 

 movements than the species of other Trichoniscid genera. I have 

 taken this species in Scotland, the North of England, London and 

 Brussels. 



ONISCIDi2E. 



Onlscus asellus, Linn^. — Common. 



Forcellio scabcr,, Latr. — Common. 



Porcellio dilatatus, Brandt — A few. 



IVlctoponorthus pruinosus, Brandt. — \Ve only saw one or two 

 specimens of this pretty woodlouse. though, as a rule, M. pruiuosus and 

 J\ dilatatus are found in profusion in or near hothouses. 



ARIVIADILLIDIID>E. 



Artnadillidiuin nasatum, Budde-Lund. 



Rather common in one of the hotter houses. This species will, no 

 doubt, be found in hothouses throughout Europe. It is usually found 

 amongst the pebbles used in many greenhouses to stand the plants 

 upon, and is also found at the roots of the different plants. It occurs 

 in hothouses in the Clyde area, Northumberland, Durham, Kew Gardens, 

 Antwerp, and Brussels ; in fact, in such situations I have found A. nasaiian 

 Avherever I have searched for it.

IRISH SOCIETIES. 



ROYAL ZOOLOGICAL SOCIETY. 



Recent gifts include four Pigeons from Mrs. Downs, three Barbary 

 Doves from Mrs. Dent, a Yellow-cheeked Amazon from Mrs. Pater, two 

 Meadow-pipits and two Corn Buntings from Mr. "W. F. Williams. 



The newly-arrived Yak Irom Tibet has now been placed in one of the 

 cattle -paddocks, and his characteristic points ma}- be readily compared 

 with those of the Indian Zebu bull andthe Anoa from Celebes, which are 

 in adjoining enclosures. The Yak is in good health, and very lively. 



DUBLIN MICROSCOPICAL CLUB. 



Drckmber 9.— The Club met at Leinster House, Dr. G. H. I'RTHV- 

 BRiDGE (President) exhibited the fungus Diplodina salids^ West, growing 

 on the bark of a willow, probably Salix iriandra, from near Limerick. 

 The fungus is new to Ireland, and appears to have been recorded only 

 twice previously, namely, from Kew (^Grevillfa, xiv., 1S85-6, p. 64), and
