Art. XLIT.—WNotice of a new fossil Annelid (Helminthodes an- 
tiquus), from the Inthographic py a Solenhofen; by O. C. 
Marsa, F.G.S., of New Haven, C 
DuRING a geological excursion which I recently made through 
the south of Germany, I spent several days at the lithographic 
quarries of Solenhofen, in Bavaria, and was so fortunate as to 
obtain a rich suite of fossils from that well known locality. 
One of the most interesting specimens in the collection is a 
new Annelid, which is so well preserved that not merely the 
outer form, but also the inner structure, can be determined with 
considerable certainty. The fossil is about 84 inches in length, 
and 2 of an inch in breadth. The alimentary canal is straight, 
of nearly equal size throughout the body, and appears to be 
filled with its original contents. 
This is, I believe, the first instance in which any part of an 
Annelid itself has been found preserved; the fossil remains 
hitherto referred to this class being either calcareous tubes allied 
to Tubicola, or certain impressions, ; tracks, and borings attributed 
to Annelids, but most of them more or less problematical as 
regards their ori igin 
At the last meeting of the Geological Society of Germany, 
held here on the 6th inst., I mentioned the discovery of this spe- 
cimen ; and, as it was evidently quite different from ang Ee 
previously meri I proposed for the species the mame He 
minthodes anti 
A careful eobipdtach with living forms will probab ly be ne- 
cessary to determine the true position of this fossil among the 
Annelids, to which class it undoubtedly belongs, diciough's some 
points in its structure seem to indicate other affinities. A 
description, with illustrations, will soon be ready for publication 
in the American Journal of Science.
