Cassidutina laevigata, D'Orb.— Rare. 



C. crassa, D'Orb. — Very common. 



Lagena apiculata, Rss.— Rare. 



L. seriato-granulosa, Rss..^— Very rare. 



L. squamosa (Mont.)— Very rare. 



L. hexagon a (Will.)— Very rare. 



Nodosaria orthopleura, Rss.— Very rare. This is a Crag species. 



N. hispida, D'Orb.— Very rare. 



Rhabdogonium tricarinatum (D Orb.) -Very rare. 



Lingulina tenera, Born.— Very rare. Common in the Antrim 

 lyias. 



Uvigcrina angulosa, Will.— Common. 



U. nodosa, D'Orb.- Very rare. Common in the North of Ireland 

 Chalk. 



Cristellai*ia cultrata (Mont.) Very rare. 



CIobIgei*!na bulloides, DOrb.— Very common. 



C. crctacea, D'Orb. —Frequent. A Chalk fossil. 



C. asqui lateral is, Br.— Common. A Chalk fossil ; it has also been 

 dredged off the West of Ireland, but the Kill-o'-the-Grange specimens 

 look similar to those found in Chalk. 



Orbulina universa, D'Orb.— Rare. 



Discorbina rosacea (D'Orb.)— Very rare. 



D. sp. — Very rare. 



Rotalia Beccarii (Linn6).- Very rare.

Nonionina depressula (W. & J.)— Very common. 



N. orbicularis, Br. — Frequent. 



N. scapha (F. & M.)— Rare. 



Polystomella crispa (Linne). — Rare. 



P. striatopunctata (F. & M.)— Frequent. 



Mr. Wright remarks that Foraminifera are quite abundant 

 in the clay ; the fauna is in general what one would expect 

 to find in shallow water around our present coasts, but mixed 

 with these are derived species, some of them being compara- 

 tively plentiful ; these derived forms are clearly distinguishable 

 from those properly of the clay by their chalky texture, as 

 well as by their generic and specific characters. 



Viewing generally the Kill-o'-the-Grange fauna, and leaving 

 out species certainly derived from older formations, and species 

 whose identity is doubtful, we have first a group of twenty-two 

 mollusca — fifteen lamellibranchs, a scaphopod, and six gastro- 

 pods ; of these, one species {Astarte borealis) is an arctic shell, 

 not now found in the British area. Several others, such as 

 the remaining species of Astaric, Panopcca norvegica^ and 

 Mytihis modiohcs, have now outside of Britain au entirely
