On the ventral face there are, as most connnouly in the Skates, no thorns at all. A vounger male, 201""" long and 106™'" broad, from the Davis Strait 1235 fathoms) with minute genital appendices is mentioned by me previoush' (1. c. 1891, p. 32). I therefore restrain myself to some brief remarks on this specimen, compared with the here described adult males. The point of the snout is hardly visible as such. The pectoral margin of the disk is slighth' sinuous, not forming a quite straight line; but a sharp incision does not occur. The back is quite covered with small spines until towards the posterior margin of the pectoral fins; also the ventral fins are partialh- thorn\', while at a later stage the\' are naked. But between this uni- form clothing of the trunk, the fins and the tail some spines a little larger make their appearance, some on the back of the snout, 3 pairs of supra- orbitals, one pair of suprascapulars and a single row of about 37 in the median line of the back, com- mencing behind the head and continued almost to the dorsal fins on the tail — accompanied on the back of the tail by middle-sized spines forming the transition to the general clothing with spinelets. Thus during the growth of the animal a rich development of larger spines takes place untill the abo\-e described stage of evolution is attained. The color of the back is brown with s
