Notes on American Land Shells. Baie 
 acerrus, demissus, and the Roan Mountain variety, are certainly very 
closely connected by varietal characters. 
16. Z. subplanus, Binney.—T his exceedingly rare species was found 
in very small numbers on a spur of fron Mountain, as well as at a 
single locality on Roan. The station was under laurel leaves, in laurel 
thickets, and on a vein of decomposed quartzite. 
The shells are larger than Mr. Binney’s type, and very closely re- 
semble the Z. ‘nornatus, Say, except in being depressed above and 
below, and in having about one whorl more. 
A careful dissection of the animal has shown me no characters sep- 
arating it from énornatus. How far the fact of an extra whorl can be 
relied upon as a specific character may be inferred from the fact that 
many species in the mountains exhibit enormities in this regard. This 
shell is extremely rare, and from the difficulties surrounding its cap- 
ture is likely to remain so. 
17. Z. inornatus, Say.—A few specimens of the typical form of this 
shell occurred on the western slope of Roan. It did not occur with 
subplaaus, whose only company was the V. latissima, Lewis. 
18. Z. sculptilis, Bland. A few specimens of this rare species were 
found in the moss growing on the boulders lying in the valleys radia- 
ting from the western side of Roan. At other localities I have found 
it under logs, occupying nearly the same stations as its close ally, Z. 
indentatus, Say. The latter I did not find. 
19. Z. elliott’, Redfield.—This species was found in considerable 
numbers, deeply buried in the rotten part of old logs, or on the under 
surface where they were deeply buried. The animal is carnivorous, 
devouring the Patula perspectiva, Say, found in the same stations. I 
have collected this shell at several localities in Kentucky and Ten- 
nessee, as well as in both the northern and southern extremities of 
North Carolina. 
20. Z. cerinoideus, Anthony.—A few specimens only, associated 
with Z. sculptilis and Z. andrewsi, W. G. B. 
21. Z. placentulus, Shuttleworth.—This shell has been generally re- 
ferred to Z. capsellus, Gould. Mr. Bland makes the above determina- 
tion, and says, “1 do not think, at least [do not remember, that I ever 
saw the true capsella, Gld., but must have done so in Binney’s coll.” 
It is of interest to note this fact distinctly, that collectors in this 
region may be on the look out for the “ true capsella.’’ The shell in 
question is very rare, and occurs in moss and about moist boulders, 
like sculptilis and cerinoideus.
