Van Straelen, I have been able to examine the holotype of this species preserved in the Musee Royal d'Histoire Naturelle de Belgique. This is 180 mm. in total length and is in excellent condition. It was taken by the 'Belgica' at 71° 14'S, 89° 14'W, at a depth of 450 metres. The 'Pourquoi Pas?' obtained 4 examples from 70° 10' S, 80° 50' W, at a depth of 450 metres, one of which (in a poor state of preservation) has been examined by me in the Paris Museum. The 'Aurora' obtained a single example, 208 mm. in length, from 64° 44' S, 97° 28' E, at a depth of 670 metres. The extent to which the lower lateral line is developed seems to be somewhat variable. In the holotype it appears to be represented by about 18 scales on the left side, whereas, on the right side it is longer and is represented by at least 30 scales. Roule, Angel and Despax remark that in the specimens obtained by the 'Pourquoi Pas?' this lateral line is unequally developed on the two sides of the same fish, and Waite records the same condition in his example. Three of the specimens taken by the 'Pourquoi Pas?' in January were mature females, and contained large eggs, varying in size from 2-5 to 3 mm. Genus RACOVITZIA Racovitzia, Dollo, 1900, Bull.
