We report the occurrence of Lithodes turkayi (Anomura), Libidoclaea granaria, and C. edwardsii (Brachyura), in the Beagle Channel. This observation extends their range of distribution south of the previously reported limit of the Straits of Magellan. Acanthocyclus albatrossis (Brachyura) occurs south of Isla Navarino and also in the Beagle Channel, however in a particular habitat of its northern coast. The occurrence of Lithodes confundens (formerly identified as L. antarcticus) north of the eastern entrance of the Straits of Magellan is also reported. We extend its range of distribution northerly and its bathymetric distribution to the intertidal. En este artículo describimos la presencia de Lithodes turkayi (Anomura), Libidoclaea granaria, y Cancer edwardsii (Brachyura) en el Canal del Beagle, que extienden su rango de distribución al sur del Estrecho de Magallanes. Notificamos aquí la presencia de Acanthocyclus albatrossis (Brachyura) en un único habitat con particulares características de la costa norte del Canal del Beagle. También describimos la aparición de Lithodes confundens (registrado previamente como Lithodes antarcticus) en el intermareal al norte de la entrada oriental del Estrecho de Magallanes, extendiendo su rango de distribución hacia el norte y su distribución batimétrica hasta el intermareal.
