Remarks.
Decamastus gracilis was described from Southern California (USA) and Bastida-Zavala (1995) reported it from La Paz Bay. After examination of Bastida-Zavala's materials we conclude that they correspond to Dasybranchus parplatyceps and that the record of Dasybranchus gracilis from México is erroneous.
