Nine homogehous glycosphingolipids were isolated from the earthworm, Pheretima asiatica (Annelida). All of them are digalactosylceramides carrying a choline phophate group in the outer galactose moiety. Their full structures including the position of a phosphocholine unit were determined based on chemical and spectral evidence.
