RECORD OF, A SHORT CoOL; 
LECTING TOUR IN WHITE 
HARDIN & GALLATIN 
COUNTIES, ILL. 
BY A. A. HINKLEY, DUBOIS, ILL. 
HILE collecting last August in White 
and Gallatin Counties, Illinois, the 
writer found Lzthasia obovala, Say, 
in abundance in the [Little Wabash and Saline 
Rivers. All specimens taken were covered 
with a dark ferruginous deposit which being 
removed presented a dark brown or olivaceous 
epidermis, many having two faint red bands on | 
the body-whorl. All were decollate, from one 
to four whorls remaining. The full grown 
shells were usually .50 to .75 inches long and 
about .40 inches wide, some unusually large 
ones being over an inch long and .60 inches 
wide. 
At the Ford of Saline River, near Saline 
Mines, the bed of the river is almost a level 
layer of rock with a. abrupt fall of twelve to 
eighteen inches, below which for a short dis- 
tance the water is broken into small, swift 
streams and shallow still places nowhere over 
a foot deep, enough rock being above the wa- 
ter to enable a person to explore the entire bed 
ofthe stream without wading. Here the Lith- 
asias were found everywhere, but most numer- 
ous in the crevices at the fall, where were also 
found Pleurocera, Vivipara, Melantho and 
Lioplax.  Goniobasis costifera, Wald., was 
common in all the small streams of Hardin 
County, presenting considerable variation. 
VALVES. 
' ber of land and fresh-water shells. 
Shark River near Key East, N. J.is a very | 
interesting locality for the young conchologist | 
to visit. 
Mrs. Mary B. A. King, of Rochester, N. Y. 
is an enthusiastic collector of shells, although 
in her eighty-ninth year, and received great en- 
couragement from the late Isaac ILea, L.L.D., 
who named the Unios and Anodontas in her 
collection upwards of forty years ago. 
Professor John M. Holzinger of Winona, 
Minn., writes us that The Conchological Club 
of the State Normal School collected over 45 
species of Univalves and 20 species of Bivalves 
last season in Winona County. The Club add- 
ed many interesting specimens to its cabinet. 
The latest report of the Liverpool Marine 
Biology Committee shows the great value of — 
marine dredging. Prior to 1853, but 270 spe- 
cies of marine invertebrates were known. The 
Committee places on record 913 species, of 
which 235 have not before been found in the 
locality, 16 are new to British seas, and 7 spe— 
cies and 3 varieties are new to science. 
A fine chance is presented to you on page 
55 of this number whereby you may secure 
valuable books to aid you in collecting. A 
portion of your leisure time may be very profi- 
tably devoted to securing subscribers to this 
your paper, and thus we will be enabled to ex- 
tend our acquaintance and you will receive a 
handsome reward. 
Recipe for cleaning shells:—Mr. B. G. See- 
bach of Peru, Ill., kindly sends the following: 
Mix 5 lbs. Sal Soda in § gallons of hot water; 
after the soda has dissolved let the mixture 
cool, Then put the live shells to be cleaned 
in tnis and leave them there for 3 or 4 days. 
This softens the tissues and the fleshy portions 
can be removed easily without deteriorating 
the shells. The mixture may be made in 
smaller quantities but in the same proportions. 
Mr. F. A. Sampson, of Sedalia, Mo., made a 
trip through Carroll County, Arkansas,in March, 
1886, and succeeded in collecting a large num- 
His visit 
there and the lengthy list of shells collected, 
show that Carro]l County is a locality of great 
interest to the conchologist.
