 a wide distribution as a recent form. 



It has been recorded by Howchin from the Lower and Upper Beds at 

 Muddy Creek, where, as in common with our examples, the test is very 

 small.

Grenus Ehrenbergina, Reuss.

Ehrenbergina serrata, Reuss, 1849, Denksclir. d. k. Ak. Wiss. Wien, vol. i. p. 377, pi. 48.

This ornate little form is well-known as a Miocene fossil (Reuss and 

 Karrer), and it has been found in various West Indian Tertiary deposits, as 

 the (r/o6^^6'ri/^a-Marls of Barbados (Chapman).
