The paper has two parts. The first part comprises and illustrated identification key of the 22 species of the Rajidae Family that authors recognize in the study area. The second part includes a design of the dorsal face, a brief description and a chart distribution given for each species. Given the fact that, with a few exceptions, all species are named skates ('rayas'), common names are suggested by the authors.
