Raja burgeri, Delfin, 1902, Revist. Chi/., vi (4), p. 267, pi. xii. Disc broader than long, its width f to | of the total length; anterior margins scarcely undulated; outer angles rounded. Vent about equidistant from tip of snout and end of tail or nearer to the latter. Snout with a very small blunt projection, but no barbel- like process, its length 5^ to 6^ in width of disc; interorbital width 3 to nearly 4 times the longitudinal diameter of the eye, which is much less than the width of the spiracle; length of eye + spiracle z\ to z\ in that of snout. Internasal width about i| in praeoral length of snout. Mouth nearly straight or with a shallow emargination in the upper jaw; 40 to 44 rows of teeth in upper jaw. Upper surface of disc mainly smooth, but with areas of minute spinules on anterior margins of pectoral fins, on the snout, round the eyes, and along the back; sometimes a patch of larger spinules on the hinder part of each pectoral; some- times an irregular median row of enlarged spines from the nuchal region to the first dorsal fin, sometimes 10 or 11 lar
