As the examination of the yarious gatherings of Foraminifera made 

 last year off the Dublin and Wicklow coasts hare not yet been fully 

 completed, the present brief Keport is now furnished, pending the 

 detailed results which we hope to have ready for publication next 

 year. The following particulars are given to show what has already 

 been accomplished. Previous to the grant having been given, one 

 of us had made a number of shore gatherings in the vicinity of 

 Dublin, and the list of the Foraminifera found was sent to the 

 Academy at the time. Since then thirty dredgings have been 

 secured — three in Dublin Bay, the remaining twenty-seven off the 

 coast — extending from D^eland's Eye to Bray Head, and as far off 

 land as the Kish and Bray Banks, the deepest parts dredged being 

 off Bray Head in twenty-six to twenty-seven fathoms. We are also 

 indebted to llr. Stephen Yoysey, of "Blanna" fishing smack, for six 

 gatherings taken off ilourne Mountains, off Howth, and off the Isle of 

 Man. The Foraminifera which we have already met with number one - 

 hundred and twenty-four species and varieties, or about two-thirds of 

 our British forms. Twelve of these are additions to the Irish Fauna, 

 one {Nodosaria Mspida) is new to Britain, and two {Lagena mrvilineata 

 and Nojiionina pauperata) are new to science. The only other locality 

 in Britain which has yielded so large a number of Rhizopoda is the 

 Estuary of the Dee, a spot which has been most carefully examined 

 by Mr. Siddall and Mrs. Shone, and where even a still greater number 

 of forms have been found. When we consider the short space of time 

 already spent in the examination of this part of our coast, our results 

 are most encouraging, and leave little doubt that a renewed search 

 would still further increase the numbers, and lead to the discovery of 

 other rare forms.
