III. RECENT DISCOVERY OF ANNELIDES AND THE SUPPOSED TRACK 
OF A GASTROPOD MOLLUSC, IN THE CARBONIFEROUS SHALES 
OF RHODE ISLAND. 
During excavations for a sewer made in Division St., Pawtucket, 
R. I., in the spring of 1888, an apparently rather thin bed of black 
carboniferous shale was found by Rev. E. F. Clarke to be not only 
rich in ferns, but unexpectedly rich in animal remains. With the 
help of a friend whom he had interested in collecting fossils, Mr. 
Clark discovered the remains of a cockroach belonging according 
to Mr. Scudder to the genus G-erablattina ; also a species of har- 
vest man (Architarbus) . It will be remembered that a year or 
two before this Mr. Clark discovered in the carboniferous beds of 
Bristol, R. I., the remains of Mylacris packardii Scudder. 
From the Pawtucket beds on Division St., my young friends, 
Mr. Henry Scholfield and Mr. F. P. Gorham, have obtained several 
specimens of Spirorbis carbonarius ; and Mr. Scholfield has found 
what is apparently the impression of a worm, most probably an 
annelid, and what appears to be the track of a gastropod mollusc, 
besides other cockroaches. 
From this bed, then, have been taken the traces or remains of 
a mollusc, two worms, a species of the arthropod order Arthrogas- 
tra, and several insects, allied to the cockroach. 
The age of this bed has been determined by M L. Lesquereux 
after the examination of a collection of plants collected and pre- 
sented to the Museum of Brown University by Rev. E. F. Clark 
and Mr. C. Williams, both of Providence, R. I. M. Lesquereux 
writes : “These specimens taken altogether are interesting as indi- 
cating more than any other lot I have seen of fossil plants of 
Rhode Island, the stratigraphical relation of your coal strata to 
those of the upper part of the anthracite measures of Pennsylva- 
nia, where, even, I have not observed such a predominance of 
species of Odontopteris typical^ allied to those described by Fon- 
taine and White from the Upper Carboniferous of Pennsylvania.” 
Spirorbis carbonarius. Three tolerably preserved specimens 
attached to the leaves of ferns were found by Messrs. Scholfield 
and Gorham in the Pawtucket plant bed. They agree with better 
preserved specimens from Cannelton, Pa., received from Mr. Lacoe, 
both in size, and the peculiar flattened shape of the outer whorl, 
but the Pawtucket specimens only show faintly the transverse
