Abstract

Skates of the genus Bathyraja belong to the subfamily Arhynchobatinae in the family Rajidae. This family is comprised currently of 228 recognized species and about 50 unnamed species (McEachran and Dunn, 1998). Some authors elevate the Arhynchobatidae to the rank of family (Nelson, 2006). Two unnamed species of skates Bathyraja sp. 2 and Bahtyraja cf. eatonii were examined and measured in the preparation of formally describing these species. A total of 20 preserved specimens of Bathyraja sp. 2 and a total of 4 preserved specimens of Bathyraja cf. eatonii, collected during the 2008- 2009 AMLR survey cruise of the South Orkney Islands, were measured. The measurements of each skate were taken following the measurement descriptions in Hubbs and Ishiyama (1968). The body proportions of B. sp. 2 and B. cf. eatonii were compared and contrasted and a preliminary species description of each species is given.
