70 THE NAUTILUS. 



GENERAL NOTES. 



LAND SHELLS OF BERKS Co., PENNSYLVANIA During August 

 of the present year I spent some days in Amity township, Berks 

 Co., Pa. Only a few hours were given to collecting, the following 

 species being obtained: 



Polygyra albohibris (Say), P. tridentata (Say), P. hirsuta (Say). 



Vallonia pulchella (Mtill). 



Bifidaria arm if era (Say). 



Pyramidula striatclla cotskillensis (Pils.). 



Helicodiscus lineatus (Say). 



Zonitoides arbor ens (Say). 



Gastrodonta suppressa (Say). 



Vitrea rhoadsi Pils., V. indent at a (Say). 



Agriolimax campestris (Binn.). 



This extends the range of Pyramidula striateUa catskillensis, not 

 hitherto found in Pennsylvania, and adds another locality for Vitrea 

 rhoadsi. The other species are of course common and widely dis- 

 tributed H. A. Pihbry. 



PHYSA CUBENSIS IN FLORIDA. The small, slender, glossy 

 Physa of peninsular Florida often goes under the name P. pomilia 

 Conr., in collections. Recognizing that this was incorrect, I gave 

 the MS. name "P. heterostropha peninsula " to the specimens col- 

 lected at Miami by Mr. S. N. Rhoads (this journal, p. 48). On 

 comparing with Antillean forms I find that the species is Physa 

 cubensis Pfr., described from western Cuba. H. A. Pihbry. 



SHELLS COLLECTED AT OAKDALE, MORGAN Co., TENN Dur- 

 ing a few hours stay, the following species were collected on the 

 bluffs along the Emory River.
