SHELLS WITHIN CITY LIMITS. 



While liunting for fossils in an old stone yard in Sedalia, I found 

 that the Pupa fallax, Say, was quite plentiful, some stones of the size 

 of a hand having nearly one hundred shells on the under side. 

 Short searches on three different days gave about 2000 Pupa fallax, 

 250 Pupa riipicola, and 10 Zonites mmusculus. 



The stone yard is in the suburbs, and is grown up with grass, be- 

 ing surrounded by unbroken prairie. I had never before found any 

 land shells in the city, nor either species of Pupa so abundant in any 

 other part of the county. My surprise was increased a few days 

 after to get large numbers of Vallonia pulchella collected by Mr. R. 

 A. Blair on a vacant lot within a block of the business center of the 

 city, being the first record of this species being found in the State. 

 Along with these latter shells, were found two Zonites arhoreus. 

 This year has evidently been a favorable one for shell life, as it has 

 been in this county, also, for fruits and vegetables.

The United States Collection. 



The announcement in the last number of the Nautilus, of the 

 proposed formation of a great National Collection of United States 

 Mollusca, to be deposited for permanent exhibition in the Academy 

 of Natural Sciences, Philadelphia, has excited much interest among 

 the members, quite a number of whom, have signified their inten- 

 tion of contributing specimens. The following is a sample of letters 

 received by the President :
