last, so far) Strepomatide of the trip, Goniobasis solidula Lea. The 
bank below the water-line was covered with them. In many places 
little springs trickled down the bank, and in these they were to be 
found to a height of twelve feet above the river level. Notwithstand- 
ing the very low stage of the river, I have seen no living Unionide, 
and only a few worn and faded valves on Burford’s Bar. 
“In the the bluff at Peach Tree there is a narrow stratum of 
ferrugineous sand containing a few Eocene fossils. Monday, the 
15th, was spent at Gregg’s Landing, four miles below Peach Tree. 
As there were no accommodations there for staying over night, we 
made every minute tell. It is a fascinating spot; great masses of 
a hard fossiliferous sandstone in which Turritella mortoni and Ostrea 
compressirostris predominate, and which has come from an upper 
stratum seventy or eighty feet above the present water-line, 
lay strewn along the base of the cliff, reminding one of Potomac 
Creek, Va. In the lower fossiliferous stratum, of a dark, indurate, 
sandy clay, Cardita planicosta, Cucullea sp., Turritella humerosa, 
Turritella sp. and Calyptrephora trinodosa, were the conspicuous 
ous forms. 
“Bell’s Landing, five miles below Grege’s, was next visited. 
The fossils were similar to those found at Gregg’s, but among them 
were many rare species—rare in collections and rare at Bell’s 
Landing. 
“Tt was indeed singular how many uniques of some very inter- 
esting forms I found here. The stratum referred to above was also 
present here, but the upper one was for the most part a soft sand, 
and contained a greater number of species. As it was impossible to 
work the upper stratum in place, and as both were mixed together 
in the talus at the base of the cliff, I found it impracticable to 
keep the fossils of the two separate. I have not had time to hunt 
for land shells, but from appearances it seems somewhat unfavor- 
able. On the bluffs it is extremely dry, while the lowlands are 
subject to overflow. To-morrow I go to work at the Claiborne 
fossils. Yours sincerely,

POLYGYRA (STENOTREMA) HIRSUTA ON LONG ISLAND.

In the October number of the Naurixus I noted a catalogue of 
the land shells of Long Island, N. Y., by Mr. Henry Prime, which
