Fragments of the lantern in a specimen of Pygaster trigeri Cotteau, from the Bathonian of France, show that previous hypotheses of the relationships of Pygaster need to be reconsidered. The action of Durham and Melville (1957) in establishing a separate order for the Pygasteridae is held to be justified.
