This paper mentions the presence of Scyllarides brasiliensis Rathbun, in the littoral zone of the State of S. Paulo. The author examined 5 specimens (2 and 3 ) from Ubatuba and 8 (4 and 4 ) from the Island of Vitória, along the northern coast of the State, in the surroudings of the island of S. Sebastião. Many of the specialists that studied the group overlooked the work of Gill (1898) that splitted the genus Scyllarus in Scyllarus and Scyllarides and thus several species that ougth to be placed in the latter mentioned genus are still described as belonging to Scyllarus. Most of the species that inhabit the brazilian coast must be referred to Scyllarides. The author compares the measurements of the present specimens with those studied by Verrill and Kathbun, and rapidly refers the species' habits and its economic value.
