A pot of snake worms

All was quiet yesterday afternoon. My usually busy office was empty but for me, the two single-office researchers and the curator on my floor were away and nobody was using the labs. So when a visiting retired scientist came wandering up looking for somebody, he came to me. He said he was in the process of slimming down his collection of parasitological paraphernalia and wanted to donate some specimens to the museum. He handed over an ancient hummus pot filled with specimen jars:

Each containing snake worms: parasitic worms from snakes. Needless to say, these are rather difficult to come by. They're now on the curator's desk, hopefully destined for the vaults.
