January 25, 1887.—Professor Ryder called attention to the exist- 
ence of pathological growths in the lower animals, and described 
a lobulated tumor from the heart of an oyster, a mass of organic 
tissue formed in the fore part of a shad’s alimentary canal, and 
the degeneration of the Wolffian bodies of a goldfish. A letter 
from Miss A. M. Fielde, describing the geology of Southeastern 
China, and accompanied by specimens of the rocks, was read. 
Granite, trap, and unfossiliferous red sandstone were among the 
rocks. Miss Fielde also announced the collection, around Swa-. 
tow, of several forms of rhizopods identical with those described 
by Dr. Leidy from Philadelphia. Dr. McCook stated that Formica 
fusca, the.ant enslaved by F. sanguinea and Polyergus lucidus, 
builds, when exposed to the attacks of the latter, a formicary, 
which is quite flat and has all its entrances concealed by grass 
and chips of bark. When the same species deems itself secure 
it forms a mound, over which openings are scattered without 
attempt at concealment.
