24 KANSAS CITY REVIEW OF SCIENCE. 
At different points having south and west exposures I found Polygyra samp- 
soni, Wetherby, but they were most abundant on a hill near King's River, where 
I got fifteen or more under each of five stones. This species varies in size, the 
larger ones having a much wider umbilicus and being 9 mm. in diameter, while 
the smaller were not 7 mm. in diameter. 
In June and July, 1881, Physa gyrina were very plenty near the springs 
along West Leatherwood Creek, but I now saw but few of them. 
At the previous visit a branch stream had Ancylus tardus and Pisidium com- 
pressum (?), in abundance but I could not now find a single one of either. The 
reason probably is that the bed of the stream is used to some extent for a wagon 
road. 
In 1881 this stream had great numbers of the interesting shell-shaped pupa 
case of the Helicopsyche armifera, Lea, but now scarcely any were seen, while 
another kind similarly made of grains of sand, but straight, one sided, and affixed 
to the under side of stones were plenty. 
Lizards, as might be expected, were abundant, though I found only one 
snake during the four days collecting. Under one stone I counted sixteen scor- 
pions. 
In King's River I obtained fine large Pkurocera subulare and Goniobasis pal- 
lidula, both of which I got in White River in 1881, but they were quite small in 
comparison with the King's River specimens. 
In the Review for January, 1882, I gave a list of shells found in and around 
Eureka Springs, and I now give the list as corrected and added to since that 
time by Mr. C. C. Allen and myself.
