Nubecularia lucifuga, Defrance, (pi. II., fig. i). 



Nubecularia lucifuga, Defrance, 1825, Diet. Sci. Nat., Vol. XXV., p. 210 ; 

 Atlas Zooph, pi. XLIV.. fig. 3. 



Magheramorne, common (C. Elcock). 

 Sigmoilina costata, Schlumberger, (pi. II., figs. 2-4). 



Signioilina costata, Schlumberger, 1893, Mem. Soc. Zool. France, Tome 

 VI., p. 57 ; p. 203 woodcut, fig. 4, pi. I. figs. Si, 52. 



Magheramorne, frequent ; Limavady Stn., one specimen. As a recent Irish 

 species it has been obtained at Dalkey Sound, Dublin Harbour, also in a shore 

 gathering east of Horn Head bridge, Sheep Haven. At both places it was very 

 rare. 

 Articulina tubulosa, Seguenza, sp. (pi. II., fig. 7). 



Quinqtieloculina tubulosa, Seguenza, 1862, Atti. Accad. Gioenia Sci. Nat. 

 (2) pi. XVIIL, p. 119, pi. II., fig. 8. 



Limavady Stn., very rare. 

 Bulimina minutissima, Wright, (pi. II., figs, 5, 6). 



Bulimina minutissima, Wright, 1901-1902, Reade, Proc, Liverpool Geol. 

 Soc. Vol. IX., p. 163, pi. XIII., figs. 9-12. 



Limavady Stn., common. As a recent species sparingly distributed around 

 the Irish coast. 

 Lagena Stewartii, nov. (pi. II., fig. 8). 



Test circular, compressed, the two faces convex, surface smooth, peripheral 

 edge rounded, short entosolenian tube, aperture oval. 



Limavady Stn., frequent. I have named this form after the late Mr. Samuel 

 A. Stewart, A. L. S. , who was the first to discover and name the Estuarine Clays 

 at Magheramorne, and who afterwards added so largely to the record of the 

 fossils found there. 

 Lagena laevigata, var. marginato=perforata, Seguenza, (pi. II., fig. 21). 



Lagena marginato-perforata, Seguenza, 1880, Atti. R. Accad. Lincei., ser. 

 3, Vol. VI., p. 332, P l. XVII., fig. 34 



Magheramorne, very common ; Limavady Stn., frequent. Recent Irish 

 specimens very rare at a few stations. The specific name given to this shell by 

 Seguenza is misleading, as what have evidently been taken for perforations are in 

 reality short spines. 

 Lagena staphyllearia, Schwager, sp. (pl. II., fig. 9). 



Entosolenia marginata (young shell), Williamson, 1858, Rec. For. Gr. Br. 

 p. 9, pl. I., fig. 2 la. 



Fissurina staphyllearia, Schwager, 1866, Novara-Expd. Geol. (2), p. 209,

Lagena Stapliyllearia, Sidebottom, 1906, Rec. For. Island of Delos, 

 Manchester Memoirs, Vol. I., No. 5, pl. I., figs. 18-20. 



Magheramorne, all the specimens (12 in number) found in this clay were 

 very minute, and were only obtained from washings that had passed through the 

 finest sieve used (millers silk 150 meshes to the linear inch). This may account 

 for the very few specimens that have been found in British gatherings.
