Fossil Annelids from the Lower Silurian. 229 
Hi ‘there have been twenty well noted falls of meteoric 
stones; and of these just one half have fallen within the 
nearly twelve hundred kilograms—an amount twenty times 
greater than that of the other ten falls scattered over various 
regions 
I have mentioned this singular fact not that it has any cos- 
mical significance, but simply as a part of the record I keep of 
my observations and study of these curious links between 
heaven and earth. Before very long I hope to put together my 
more recent speculative studies in regard to these bodies. 
Art. XXXII. — Notice of a new genus of Annelids es the Lower 
Silurian ; by Gko. BirD GRINNEL 
THE Museum of Yale College has recently received, from 
the rocks of the Cincinnati group, a series of fossils which are 
of unusual interest. The remains are shining black in color, 
and present a striking contrast to the associated fossils, Trilo- 
bites, Brachiopods, Crinoids, ete., which have assumed the 
color and constitution of the matrix. An examination of these 
A remains shows that a are the hard chitinous parts of 
ley 
suggest Sake red com saul erith these specimens are the 
Phrou h the kindness of Professor 
arsh, the Boy ae been Bo to examine a number of 
the original specimens of these fossils, collected by Pander him- 
self near St. face lg ; and a comparison makes it clear that 
they are quite unlike t @ remains referred to. They are widely 
different in color and form from the material under observation, 
while chemical tests show that their composition is by no 
means simi 
hese Pacis fossils include a large number of specimens, 
and, as might be expected, there isa wide variation in their form. 
So little is at present known in regard to the jaws of Anne- 
lids, that any pry ee conclusions drawn from the material at 
the command of the writer would be premature; Besa for the 
same reason it would be unwise to distinguish b name each 
of the many forms which appear. Further study will doubt-
