196 The Irish Nahiralht. November, 



Porcellio pictus, Brandt. 

 Among stones at the ruins on Bray Head, and under planks of wood, 

 Greystones, Co. Wicklow. Co. Dublin : in a bathroom at Rathmines. 



Porcellio dilatatus, Brandt. 

 Greystones, Co. Wicklow, among vegetable refuse (young specimens) 

 and under wooden planks in a lan-eway used for supporting bathing 

 boxes during the winter months (numerous). Co. Dublin : in a hot- 

 house near Milltown, and in an old garden in the city. 



Porcellio laevis, Latreille. 

 Numerous under fallen slates and stones of a ruined house near 

 Blacklion, Co. Wicklow. Co. Dublin ; in an old garden in the city. 



Metoponorthus cingendus, Kinahan. 

 Six feet above high-water mark on Bray Head and at Greystones. 



The three woodHce, Porcellio scaher, Oniscus asellus, and 

 Trichoniscus pusilhis were common in all the districts 

 \'isited in the two counties, and Philoscia muscorum and 

 Armadillidium vulgar e in Co. Wicklow. Two days' careful 

 searching of ants' nests on Bray Head was unsuccessful 

 in finding Platyarthrus Hoffmannseggii, so that the species, 

 if it exists (which is probable from its surrounding 

 distribution) must be exceedingly rare. 



It is interesting to note that specimens of Trichoniscoides 

 alhidus found here in the garden at Rathmines are much 

 more coloured than those from the shores around Howth. 

 The former have ramifications of orange on the anterior 

 and middle of the mesosome, while the latter are perfectly 

 white. These latter are also perfectly devoid of eyes. 



Rathmines, Dublin. 



A GENERAL INDEX TO THE IRISH NATURALIST. 



Having frequently had occasion to refer to back volumes 

 of the Irish Naturalist, I prepared for my own use a 

 MS. index to vols. i. to xviii. inclusive, and thinking it 

 might be useful to others, got it printed. 



The index is now ready, and will be forwarded for 7s. 

 to any person who cares to have a copy. The price looks 

 very high, but even if every cop}' were sold, I would still 

 be out of pocket.
