Miliolina Williamson, 1858. 
Miliolina sp., plate YI1I. figs. 8, 4. — Two characteristic examples 
of a triloculine form occurring at rare intervals in Mr. Bailey’s pre- 
parations. We are not at all sure that these do not represent younger 
stages of Spiroloculina tenuis (supra), but as only one specimen, by 
reason of the number of its chambers, can be truly referred to that 
genus, we hesitate either to place these with it, or to impose upon 
them a new specific name. 
Cornuspira Schultze, 1854. 
Cornuspira cretacea Reuss, plate VIII. figs. 5, 6. Reuss, SB. k. 
Ak. Wiss. Wien, xl. 1860, p. 177, plate i. figs. 1 a,h. — Occurs frequently 
at Speeton. The individuals vary in shape from circular to oval, as 
shown in the figures, hut all possess the true characters of the “species.” 
Several have either grown irregularly or have been injured since being 
deposited, for they show a depressed line from margin to margin, and 
appear at first sight to belong to Spiroloculina. 
Ammodiscus Reuss, 1861. 
Ammodiscus gordialis (Jones & Parker), plate VIII. fig. 7. Tro- 
chammina gordialis Jones & Parker, Quart. Journ. Geol. Soc., 
xvi. 1860, p. 304. A. gordialis , Brady, Rep. Challenger, ix. 1884, 
p. 333, plate xxxviii. figs. 7-9. — Two specimens of this interesting 
foraminifer occur in Mr. Burrows’ washings. In one example 
the tube is thickened by subsequent deposition into an apparently 
solid boss in the centre. 
A. incertus (d’Orbigny), plate VIII. fig. 8. Operculina incerta, 
d’Orb. in De la Sagra’s Hist. lie Cuba, 1839, Foram., p. 49, plate vi. 
figs. 16, 17 ; A. incertus, Brady, Rep. Challenger, ix. 1884, p. 330, 
plate xxxviii. figs. 1-3. — Several specimens of this variable form occur 
in Mr. Bailey’s preparations. 
A. tenuis Brady, plate VIII. fig. 9. Brady, Rep. Challenger, ix. 
1884, p. 332, plate xxxviii. figs. 4-6. — This foraminifer, of which 
only one example was found, agrees so closely with Brady’s figure 
that we do not hesitate to record it as such ; at the same time we 
endorse Dr. Brady’s remark, “ that it is probably nothing more 
than a local variety of A. incertus .” Bailey Coll. 
Textularia Defrance, 1824. 
Textularia attenuata Reuss, plate VIII. fig. 10. Reuss, SB. k. 
Ak. Wiss. Wien, xlviii. (i.) 1863, p. 59, plate vii. fig. 87. — Reuss 
figures and describes this species from the Septarienthon, and states 
that it is very variable in shape. Our specimen agrees with his figure, 
except that it has fewer chambers. One specimen, Bailey Coll. 
T. pygmdea Reuss, plate VIII. fig. 11. Reuss, SB. k. Ak. Wiss. 
Wien, xlvi. (i.) 1862, p. 80, plate ix. fig. 11. — Described by Reuss from
