236 The Irish Naturalist. [November, 



brilliant of hue. Here it was that Area tetragojia was found ; 

 I did not see it elsewhere in the district. The specimens 

 were all small. At Ardara, though the shore is extensive, 

 there was nothing of interest in the way of shells ; Donax 

 vittatus and Jlfaetra solida had it all their own way. At 

 Cloonej' Bay Cardium edule was of enormous size ; Hydrobia 

 ulvce, unknown at Narin, was in quantities. 



Hoping to make discoveries if I went further from home, I 

 bicycled to Killybegs, where I spent a week. There I found 

 Mya truncata and M. arenaria (not seen elsewhere), but only 

 a few single valves of each ; Tapes deeussatus was abundant. 

 Serobieula?ia pipcrata was abundant and fine at Fintra Bay, 

 and Tellina balthiea was specially fine in colour and size. 



As August approached the debris from the sea increased in 

 interest ; the shore was often strewn with Vclclla, its exquisite 

 colour and graceful shape, at the time unfamiliar to me, 

 suggested its being a foreigner, and gave hope of finding 

 other rarities. Two waifs from the West Indies next put in 

 an appearance, the large brown bean of Entada scandens, and 

 the round grey nut of Ccesalpinia Bonducclla. 



The day before leaving Narin some friends picked up about 

 a dozen specimens of the beautiful oceanic shell Ianthina 

 rotundata, known as the " Blue Snail." They were quite fresh, 

 the animal being alive ; attached to many of the shells were 

 young barnacles which must have somewhat interfered with 

 the comfort of the " Blind Sailor." 



My best thanks are due to Dr. G. W. Chaster, who kindly 

 named many of the small shells, and to Professor Johnson 

 for identifying the West Indian seeds.
