peripheral edge of the test. Diameter 1/64 in.; thickness of test

It gives me much pleasure to associate the name of my friend 
Mr. F. W. Millett with this species ; and I will take this opportunity 
of recording my obligations to him for the many useful notes with 
which he has from time to time furnished me. 
A. Millettianus was found at Folkestone in zone iii., frequent ; 
zone viii., very rare ; zone ix. frequent ; zone xi., 55 ft. from the top, 
frequent ; 50 ft., rare ; 45 ft., frequent ; 35 ft., common ; 30 ft., rare ; 
25 ft. frequent ; 12 ft., frequent ; 6 ft., frequent.

This species is apparently characteristic of the older Cretaceous 
deposits. It is recorded by Reuss from the Minimus-clay of the Rhine 
in Westphalia, and from the Red Chalk of Speeton by Burrows, 
Sherborn, and Bailey. 
In the Gault of Folkestone this species occurs sparingly, and is 
still rarer than the Spiroplecta type which has been previouslv 
noticed.* 
T. complanata was found in zone v., very rare ; zone xi., 45 ft., 
from the top, very rare.

The above species may be regarded as an elongated form of the 
type M. glabra d’Orbigny. It was originally described by Reuss from 
* Journ. E. Micr. Soc., 1892, p. 7H, pi. xi. fig. 4.
