Reophax, Montfort. 



Reophax scorpiurus, j\[ontfort. (PI. XVIII, Fig. 1.) 



Reophax scorpmrus, Montfort, 1808 : Conchyl. Systeme, vol. i, p. 330, 



83'' genre. 

 Nodosaria agglutinans, Terquem, 1870 : Mem. Acad. Imp. Metz, 1869-70,

 Reophax helvetica, Haeusler, 1883 : Q.J.G.S., vol. xxxix, p. 27, pi. ii, 



figs. 8-10. 



Remarks. — Two specimens, difiering considerably in size, seem to 

 belong to this species, although the larger one resembles somewhat 

 R. pilidiferce, Brady (Chall. Rep., p. 292, pi. xxx, figs. 18-20). 

 R. scorpiurus is known from the Swiss Jurassic (Haeusler), the 

 Oolite of Fontoy, Moselle (Terquem), and the post-Tertiary of 

 Norway (Crosskey & Ilobertson). Chapman records it from the 

 Folkestone Gault. At present it is a very common cosmopolitan 

 species at from 3 to 3,960 fathoms (Brady). R. piluliferoi., however, 

 to which the larger specimen has affinities, is confined to deep vpater, 

 having been found from 800 to 2,435 fathoms (Brady, Chall. Ilep.). 



Horizon. — Found in Upper Co- Two specimens. 



Haplophkagmidm, Reuss. 

 Haplophragmiiim latidorsatum (Bornemann). (PI. XVIII, Fig. 3.)

vol. vii, p. 339, pi. xvi, figs. 4a, h. 

 Haplophragmiiim crassum, Keuss, 1867 : Sitzungsb. d. k. Ak. Wiss. Wien,

 H. rotimdidorsatum, Hantken, 1875 : Mittheil. Jahrb. d. k. ung. geol. Anstalt, 



vol. iv, p. 12, pi. i, fig. 2. 



Remarks. — The species has been recorded by Bornemann from the 

 Septaria-clay of Hermsdorf, near Ikrlin, by lleuss, from the Salt-clay 

 of Wielizka in Galicia, and by Hantken from the Clavulina-Szaboi 

 Beds of Hungary, all of wliich are of Middle Tertiary age. Chapman 

 records it from the Folkestone Gault, and it is at present a deep-sea 

 form according to Brady. 



Horizon. — One specimen from B base c (unfortunately lost after 

 drawing). 



Sub-family TIlOCHAMMININiE. 



Ammodiscus, Beuss. 



Anunodiscus gordialis (Jones & Parker). (PI. XVIII, Fig. 5.) 



Trochavmiina gordialis, Brady, 1876 : Monogr. Garb, and Perm. Foram., 

 p. 77, pi. iii, figs. 1-3. 



Remarks. — The species is known from the Carboniferous rocks of 

 Great Britain and Belgium, and from the Permian of Northern 

 England, and it is still living. Brady (Chall. Hep.) records its 

 presence in seas varying in depth from 50 to over 2,000 fatlioras. 



Horizon. — Found in Upper C^. One specimen.
