M. Agassiz on Shells from the Crag. 343 
XXXIX.—Additions to Mr. Wood’s Catalogue of Crag Ra- 
diaria*¥. By M. Aaassiz. 
To the Editors of the Annals and Magazine of Natural History. 
GENTLEMEN, 
Mons. Acassiz a few hours previous to his departure for the 
continent paid me a very short visit, and was able to deter- 
mine among my crag Radiaria the following genera, which I 
am desirous should be made known (having his permission), 
as there are some among them that would scarcely be looked 
for in that deposit. The list comprises all that M. Agassiz 
had seen from the crag during his sojourn in this country. 
Yours, &c. 
S. V. Woop.
