Short Description
Original description after Günther, 1872 [1066]: Disk broader than long ; snout a little projecting ; tail longer than the disk. Disk smooth, but with spines along the median line, viz. three in a single series in the middle of the back, and two on the tail, in front of the serrated spine. No rudimentary dorsal fin. Upper parts nearly uniform brownish, with a few very indistinct darker specks. Distance of the extremity of the snout from the vent 4 1/2 inches; Distance of the extremity of the tail from the vent 5 3/4 inches; Greatest width of the disk 6 1/2 inches. One example, from the Godeffroy Museum, is in the collection of the British Museum.
