274 T^^^^ Irish Naturalist. October, 



described from lakes— one described about forty years ago from the Lake 

 of Geneva ; the other lately sent me by the describer, Prof G. O. Sars, 

 from the Caspian. Now your L. Mask species comes very near, if it be not 

 the same, as the Genevan species. I have only as yet roughly examined 

 it, but all its organs must be compared. Such of your specimens as have 

 the last uropods are females. A great point of interest is that this lake- 

 dwelling species is blind, just as is the case with the well-dwelling ones." 

 The readers of the Irish Natto-alist Vf'xW remember that in 1901 (vol. x., 

 p. 91) a notice appeared noting the existence of one of these Crustacea 

 in the wells of Dublin. I send this preliminary notice of this Amphipod 

 from L. Mask, as it proves how much of interest still awaits research 



into our Irish fauna.

Irish and British Woodlice. 



In a "Supplemental List of British Land Isopoda" {Ann. and Mag. 

 Nat. Hist., vol. xi. (7th s.), 1903, Canon Norman refers to the fact that 

 Trichoniscns invidiis had now been recorded from another Irish locality — 

 viz., Cappagh, Co. Waterford — though it has not j'et been found in 

 Great Britain. 



Mr. de V. Kane's note of the occurrence in Co. Clare of Haphph- 

 thalmns Mengii {^Irish Naturalist, ix., p. 246) is now confirmed by Canon 

 Norman, and he also notes that a new Porcellio — viz., P. Ratzebiirgi — ha 

 been taken in Kngland since his original paper on the British Land 

 Isopoda was published. 



Three New Irish Beetles from Co. Dublia. 



In the Entom. Mo. Mag. for the current year (2), vol. xiv-, p. 40, Mr. 

 Stanley W. Kemp records the capture of three beetles in Co. Dublin, 

 that are additions to the Irish list. They are Hydroportis longicorrv's, 

 Sharp, from Kippure (2,200 feet elevation) ; Phytosus nigridentris, Cher., 

 from Baldoyle ; and Omalium rugulipenne, Rye, which occurs commonly 

 along the north Dublin shore at the North Bull, Baldoyle, and Sutton. 



Silpha subrotundata. — Species or Variety % 



A short article, by the Rev. W. F. Johnson, in the same volume of the 

 Entom. Mo. Mag. (pp. 99-100), supports the view that this interesting 

 Irish beetle should be regarded as a distinct species, and not as a mere 

 variety of 5. atrata. It is noteworthy that in the Isle of Man, as in this 

 country, the latter form is replaced by S, rotundata.
