Fig. 9. Distribution of Raja doello-juradoi and the other deep-water rays. First survey: triangles; second survey: squares; third survey: circles; negative observations left blank. Numbers refer only to R. doello-juradoi. g = R. griseocauda; s = R. scaphiops; a = R. albomaculata; positive records only. Raja macloviana Norman. The general spatial distribution of this species (Fig. 10) is very similar to that of R. doello-juradoi, but a consideration of its distribution with depth shows that a higher proportion of R. macloviana was taken just on the shelf, instead of just ' over the edge'; hence the.
