108 THE NAUTILUS. 



LAND SHELLS OF CHOKOLOSKEE KEY AND CAPE SABLE, FLOR- 

 IDA. Have just run across a big lot of Liguus and Oxystyla 

 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, NAUTILUS, XXI, p. 100. 



Chondropoma dentatum (Say). 



Truncatella caribaeensis "Sby. " Rve. 



Truncatella bilabiata Pfr. 



Lucidella tantilla (Pils. ). 



Thysanophora inaguensis (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 (Pfr. )? juv. 



Zonitoides arbor eus (Say). 



Zonitoides minusculus (Binn.). 



Oxystyla fioridensis 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 Lucidella 

 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 

 fioridensis 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. GEORGE H.
