They’re matte, iridescent. Smooth, spiky, knobbly. Bulbous, flat, pointy. Seashells come in all manner of shapes and sizes, to suit the delicate creatures who live in them. Come explore the Wagner’s incredible mollusk collection—one of the nation’s largest and most complete—in the company of a seashell expert. Malacologist Paul Callomon will guide a small group of participants through our cases, where you’ll find mother of pearl, perforated quahogs, translucent argonaut shells, and of course the iconic Nautilus. Paul will explain why our collection is laid out the way it is, why it’s so tricky to define a mollusk, and what it has meant to be a shell collector over the last couple of centuries. And you’ll enjoy wine and cheese as you listen.

Our Evening with an Expert series highlights the original purpose of the Wagner museum—to stand as a complement to the lectures and courses, so that students could explore scientific principles by examining real specimens in the presence of a guide or professor. Our Evening with an Expert series brings in local scholars to guide small groups of people through specific areas of our collection.
