ShellsThings of Science unit from January, 1962 on sea shells. With the illustration from the booklet to the one side here and the photo of the “things” below, it took me but a few seconds to identify each shell below. (I wish now I had placed them to match the illustration when I imaged them.)

Here is the booklet:

Things of Science #255 — Sea Shell
