214 Mr. Henry B. Brady on 
ations respecting the relation of the marine Rhizopod fauna of 
our coast to that of its adjacent brackish waters, first, with 
respect to distribution, and, secondly, with regard to modifica- 
tions in the external characters of species common to both, 
due to altered conditions of life. 
comparison of the Table of Brackish Foraminifera with 
the complete list of species known to inhabit the British seas 
will show that the number of types or subtypes that entirely 
refuse to accommodate Ma Las to brackish conditions in 
been excluded from the list. Hauerina, Lingulina, and Nu- 
* Nubecularia has not hitherto been recorded from a British locality ; 
but I have WP of N. lucifuga from deep water in Mounts Bay, 
Cornwall.—H. B. B.
