108 THE NAUTILUS. 
LAND SHELLS OF CHOKOLOSKEE KEY AND CAPE SABLE, FLor- 
1pA.—Have just run across a big lot of Liguus and Ozystyla 
that Simpson sent me 3 or 4 years ago and in cleaning them up 
I shook a small amount of dirt out of a bunch from Chokoloskee 
Key which yielded the following species. You will note that 
only two of them are in Vanatta’s list, Nauritus, X XI, p. 100. 
Chondropoma dentatum (Say). 
Truncatella caribaeensis ‘‘Sby.’’ Rve. 
Truncatella bilabiata Pfr. 
Lucidella tantilla (Pils. ). 
Thysanophora tnaguensis (Weinl. ). 
Thysanophora plagioptycha (Shutt. ). 
Gastrocopta contracta (Say). 
Gastrocopta rupicola (Say). 
Gastrocopta p. hordeacella (Pils. ). 
Varicella gracillima floridana Pils. 
Euglandina rosea, near parallela (Binn. ). 
Polita dalliana (‘‘Simp.’’ Pils. )? juv. 
Guppya gundlachi (Pfir.)? juy. 
Zonitoides arboreus (Say). 
Zonitoides minusculus (Binn.). 
Oxystyla floridensis Pils. 
The most interesting of the lot is Lucidella tantilla ; there is 
one perfect adult, three fresh shells that have been bitten in 
half by some rodent (?), several other fragments and three 
young. As I only had enough dirt to about fill a 2 x 3 tray 
you can see it was quite rich. I have noticed that Lwucidella 
tantilla appears to be a favorite food with some beast that bites 
them fairly in half. Gastrocopta rupicola is frequently treated 
in the same way, but it is so common that it does not make so 
much difference. 
Three miles east of Cape Sable, Simpson collected Oxystyla 
floridensis and some Liguus that I take to be solidus, although 
they are all very thin. They are all dead, but the yellow band- 
ing of solidus shows on some of them very plainly.—GrorGE H.
