One unnamed Zonites bears considerable resemblance to Z. lima- 
tulus, but is of only three mm. diameter, more depressed, sutures 
less impressed and outer whorl more rounded, and having four 
whorls. 
The other unnamed one has the general size and appearance of 
Z. arboreus, but has six whorls. These were both found on the 
Boston Mountains. Zonites brittsi was described in the NauriLus 
of last January. The type specimens were collected by Mr. R. A. 
Blair, of Sedalia, in Garland County near Hot Springs. They are 
very close to Z. demissus. 
Patulu solitaria has not before been recorded frem as far south. 
Very few specimens of Polygyra texasiana were found in the State, 
but they were very abundant in the Indian Territory across the 
river from Fort Smith. In no county except Garland were both 
dorfeuilliana and its variety sampsoni found. The latter was 
most abundant in Carroll County, fifteen or twenty being frequently 
under one stone. P. jacksoni was much larger than typical size on 
the bluffs at Van Buren. But one Z. obstricta was found, and that 
a dead one, near Batesville. 7. edentata were collected on the Bos- 
ton Mountains in Franklin County. They are larger than injlecta 
and almost or entirely without teeth on the peristome. T. fallaz, 
from the northwest corner of ‘the State, were quite small, and many 
of them albinos.
