1896.] Warren. — The Terns of Killala Bay, 153 



miles further north, near Raughly, in Brown's Bay, where a 

 dozen pairs frequent a flat at the base of the sandhills, and 

 lay on the bare pasture between the tufts of bent grass. 



The BivACK Tern {Ste7 7ia nigra). — So rare a species in 

 Ireland has only once come under my notice as a visitor to 

 Killala Bay, and it was by the merest chance I came across 

 it as I was fishing for Sea-trout near Bartragh on the 12th of 

 October, 1859. 



My boat was anchored in the channel between Baunross and 

 a wide stretch of sand-banks left bare by the ebb-tide, and 

 while fishing I remarked a group of four or five small terns 

 resting on the sand-bank close to the channel, but at first, 

 thinking they were young ComnJOn Terns, I paid no attention 

 to them. However, after a while they rose from the sand, 

 and began hawking after some flies, and the very sudden and 

 adroit twists and turns they made in the pursuit of their 

 diminutive prey showed they were birds strange to me. I at 

 once got up my anchor and rowed after them, and as they 

 were not at all shy I easily succeeded in shooting a pair of 

 Black Terns in the first season's plumage. This little party, 

 a family of terns, were evidently on their way south from their 

 breeding-haunt, but whether they were bred in this country 

 on some remote bog or mountain lough, is difiicult to say, for 

 there is no record of the Black Tern having ever bred in 

 Ireland. 



NOTES ON THE ROCK POOLS OF BUNDORAN. 



BY J. E. DUERDEN, A.R.CSC. (1.OND.), 

 Curator of the Museum, Kingston, Jamaica. 



In addition to the notes in the Irish Naturalist for January, 

 1895, upon the '* Rock-pools of Bundoran," I find I have a few 

 other observations which removal from Ireland has prevented 

 from further amplification. This latter occurrence may perhaps 

 be considered sufficient apology for their disconnected nature ; 

 while the fact that some of the specimens were collected and 

 handed to me by Prof Johnson renders it obligatory upon me 

 to present them. 



In examining the Hydroids the greenish, somewhat flask- 

 shaped tests of the Protozoan Folliculina ampulla, Mull., were 

 met with on the stems in considerable numbers.
