the Minimus- Thon of the North German gault. The specimen 
figured comes from Hunstanton (Sherborn Coll.), and is the only one 
met with. Jones and Parker record this species as “ common ” in the 
Emmett collection, from Flamborough Head. 
T. agglutinans d'Orb., plate VIII. fig. 12. D’Orbigny in De la 
Sagra’s Hist. lie Cuba, 1839, p. 144, plate i. figs. 17, 18, 32-34. — 
Occurs rarely in our collections ; the specimen figured is from 
Mr. Burrows’ washings. 
T. gramen d’Orb., plate VIII. figs. 13 a, b. D’Orbigny, Foram. 
Foss. Vienne, 1846, p 248, plate xv. figs. 4-6.— One specimen, 
Burrows Coll. 
T. trochus d’Orb., plate VIII. fig. 14. D’Orbigny, Mem. Soc. 
Geol. France, iv. 1840, p. 45, plate iv. figs. 25, 26. — Common in 
Mr. Bailey’s preparations. The chambering in all the specimens is 
obscure, and can only be made out by careful study. 
T. turris d’Orb., plate VIII. figs. 15a, b. D’Orbigny, Mem. Soc. 
Geol. France, iv. 1840, p. 46, plate iv. figs. 27, 28. — This form 
seems rare in the red chalk ; Hunstanton (Sherborn Coll.) ; Speeton 
(Bailey Coll). 
T. complanata (Reuss), plate VIII. fig. 16. Proroporus com- 
planatus , Reuss, SB. k. Ak. Wiss. Wien, xl. 1860, p. 231, 
plate xii. figs. 5 a , b. — This interesting textularian occurs abundantly 
in Mr. Burrows’, but more sparingly in Mr. Bailey’s preparations. 
The specimens vary from Reuss’ type, in that they are shorter and 
broader and have fewer chambers. 
Textularia sp., plate VIII. figs. 17a, b. — One specimen only of a 
textularian with a bladder-like final chamber, the orifice being pro- 
duced into a snout ; Burrows Coll. Dr. Brady informs us that this 
anomalous condition is occasionally met with, and therefore the 
character is not specific. It is probably a well-developed specimen 
of Reuss’s T. attenuata (supra). 
Verneuilina. d’Orbigny, 1840. 
Verneuilina propinqua Brady, plate VIII. figs. 18a, b. Brady, 
Rep. Challenger, ix. 1884, p. 387, plate xlvi. figs. 9, 10. — Specimens 
of Verneuilina in Mr. Burrows’ collection show so strong a resem- 
blance to Dr. Brady’s species that we do not hesitate to refer them to 
that form. In the figure the mouth is perhaps a little accentuated, 
the tenacious adherence of the matrix making it difficult to ensure the 
absolute freedom of the specimens. 
V. triquetra (Munster), plate VIII. figs. 19, 20. Textularia 
triquetra l. Munster in Roemer, Neues Jahrb., 1838, p. 384, plate iii. 
fig. 19 : V. triquetra , Brady, Rep. Challenger, ix. 1884, p. 383, plate 
xlvii. figs. 18-20. — Extremely common in Mr. Bailey’s preparations, 
but often obscure and difficult to determine. We have, however, no 
doubt as to its identity. In many cases, possibly from its extra-
