sagittatus, the beaks of which, according to the Norwegian naturaUst 

 Collett, are frequently found in its stomach. This cephalopod is a pelagic 

 form and may often be seen at the surface by night, fifty miles or so off 

 the west coast of Ireland, probably on its northern migration. It seems 

 likely that the specimens of the Opah which come ashore in the British 

 Isles are individuals which in the course of their northerly migration have 

 lost their way and wandered into shallow water of low salinity where their 

 apparent helplessness may be due to their unaccustomed surroundings.

The Pearl-bordered Fritillary. 



Mr. R. A. Phillips is to be congratulated in adding Argynnis Euphrosyne 

 to the list of Irish batter files. From the fact that it has been overlooked 

 for so long, it does not necessarily follow that its Irish distribution must 

 be very local, when one considers that the late Mr. \Vm. F. de V. Kane 

 worked and investigated the lepidoptera in the neighbourhood of Favour 

 Royal in this county for many years, and yet passed over Melitcea aurinia, 

 which has since been found in the locality. The chance discovery of the 

 larvae of this species on the Erris peninsula, Co. Mayo, was responsible 

 for the addition of this local little butterfly to the county list.

Aster laevis at Lough Neagh, Co. Tyrone. 



A few years ago I observed this plant sparingly in the marshy meadows 

 which fringe the western shore of the lough for miles. Last month 

 accompanied by my friend Dr. R. J. Spencer, when searching for Spiranthes 

 Romanzoffima, we found large masses of the Aster in full bloom, and 

 extending along the shore for over half a mile, and also on some of the 

 small islets in the lough. Other plants found at the same time were 

 Ranunculus Flammula and Epilobium angusHfoHum, the latter plentiful 

 in meadows reclaimed from the bog.
