Abstract
    Twenty-five species of Muricidae are recorded from south-eastern Brazil, including eight species of Muricinae, nine of Muricopsinae, one of Ergalataxinae, one of Ocenebrinae, four of Trophoninae, and two of Typhinae. A short discussion is given for each species. Three new species are described: Dermomurex leali n.sp. differs from related taxa by the presence of 5 varices on its last teleconch whorl and by its different intritacalx; Favartia varimutabilis n.sp. is compared with F. alveata, from which it differs by the erratic placement of the varices and by its multispiral protoconch; Trophon mucrone n.sp. differs from T. lacunellus, T. dabneyi, and T. limicola by its spiral sculpture, rounded teleoconch whorls, paucispiral protoconch, and number of axial lamellae. Two species remain unidentified and are listed as Muricopsis (?Murexsul) sp. and Favarita (Favartia) sp. Drupa didyma Schwengel, 1943 is synonymized with Trachypollia turricula (von Maltzan, 1884).
