Bellingshausen Sea; between South Shetlands and South Orkneys. DoUo's original description of this species was based upon three egg-capsules, each 60 mm. in length (without the horns), from 70° 15' S, 84° 06' W; 70° 23' S, 82° 47' W; and 71' 19' S, 87° 37' W; at depths ranging from 400 to 569 metres. The fish itself has not yet been recognized. Raja sp. St. 599. 17. i. 31. 67° 08' S, 69° 06-5' W. Large dredge, 203 m.: i large egg-capsule with con- tained embryo. Hab. Graham Land. The length of this capsule, without the horns, is about 200 mm., the greatest width about 80 mm. The embryo is 160 mm. in total length and measures 70 mm. across the disc. In general form the capsule is very similar to that of the European Skate, Raja batis, Linnaeus. Other species of Raja from the Antarctic Zone are R. murrayi, Giinther and R. eatonii, Giinther, both from Kerguelen.
