Thanks for all the replies, y'all. I'm broadcasting this reply to try to save trouble for responders and bandwidth for all. I was aware of the USNM designation of some adopted collections at the Smithsonian, but the source I was quoting made a clear distinction between SI and USNM, and spoke of field biologists actively and exclusively employed by each. His mistake, my embarrassment. But thanks again. Hank Burchard * <[log in to unmask]> * Washington DC
