The taxonomy of the Cyclophoridae and Pomatiasidae of the Seychelles islands is reviewed. Two species of Cyclophoridae are recorded: Cyathopoma blandfordi Adams, 1868 and C. picardense sp. nov.. Three species of Pomatiasidae are recorded: Tropidophora pulchra (Gray, 1834), T. gardineri sp. nov. and T. ligata (Müller, 1774). The last species is recorded from one small population on Cosmoledo atoll, now possibly extinct, and an isolated shell washed ashore on Silhouette Island.
