About 130 scales in a longitudinal series above the lateral line, about 12 in a transverse series between base of first ray of anterior dorsal and lateral line. Greyish; inner surface of pectoral blackish. Three specimens, 160 to 370 mm. in total length, from the Cape of (rood Hope and from Natal. This species is very distinct from the European M. vulgaris, with which it has been confounded. Scorpasna natalensis sp. n. (PI. V). Depth of body 2|- in the length, length of head 2-|. Snout longer than eye, the diameter of which is 5 in the length of head and equal to the interorbital width. Jaws equal anteriorly; maxillary extending to below the middle of eye; palatine teeth present. Head naked, except for a few rudi- mentary scales. Interorbital space concave, with a pair of weak ridges ; occiput with a quadrangular depression. A pair of nasal spines ; each supra-orbital ridge with 3 spines; a pair of spines near the extremities of the interorbital ridges; on each side 2 spines in the parieto-occipital region and below them 2 temporal spines; sub-orbital ridge with 3 spines leading to a double spine on the pr^eoperculum, below which are 3 prajopercular spines; 9 gill-rakers on the lower ])art of the anterior arch. Dorsal XII 10, the third and fourth spines the longest, as long as the longest soft rays and nearly half the length of head. Anal III 5, the second spine scarcely longer than the third, one t
