of Retade de Espirito Santo with 343 species was also prepared. As 
part of the anniversary celebration, an addenda to the list of land

AN UNUSUAL SHELL EXCHANGE 
Sam Freed 
Some years ago I had the opportunity to exchange shells with the 
Smithsonian Institution, the world's largest repository of mollusks. 
This all came about due to the encouragement of our own Karl Jacob- 
son. 
For a number of years I had been collecting land and fresh water 
shells in New Jersey, concentrating mainly in Union County where I 
resided with my family. A summary of shells collected appeared in 
"The Nautilus," Vol. 70, No. 4, April, 1957 titled "Land and Fresh 
Water Mollusks of Union County, N.J." This was the first survey of 
mollusks for the county. 
I wrote to Dr. Harald A. Rehder of the Smithsonian Institution in 
Washington, D.C. inquiring whether he would like to exchange land 
and fresh water shells from North Jersey for marine shells of the 
west coast. The answer was that since the Smithsonian had very few 
shells from northern New Jersey an exchange was most welcome. 
A package of 20 species, 110 shells was mailed to Dr. Rehder. Sev- 
eral years later I received a most interesting lot of shells neatly 
packed in round, colored, miniature hat boxes with complete scienti- 
fic data. Included were 28 species, 364 specimens. Among this lot 
were 41 shells of six paratypes. (A paratype is a specimen, not the 
holotype, but of the original series on which a Species is based.) 
The following paratypes are now in my collection:
