SHELLS FROM JAMESTOWN, NortH Daxkota.—On June 6th, 
1912, I had an hour or two to wait for a train at Jamestown, 
which I improved by taking a stroll along the banks of ‘‘ Jim”’ 
River in search of mollusks. It is not a likely-looking field for 
snails as there are only a very few scattering scrubby locust 
trees along the river banks, but the final count shows ten species, 
and as one of them is Gastrocopta holzingeri agna (Pils. and Van.) 
it may be well to put it on record, since the only other records 
for it L am aware of are in Kansas and southeastern Colorado. 
I am indebted to Mr. Bryant Walker and Dr. V. Sterki who 
carefully examined the specimens.
