Discovery reports (1940) Discovery reports discoveryreports18inst Year: 1940 Fig. 6. Eumoiphometra aurora, a, cirrus, b, proximal part of a ray. c, fourth to tenth brachials and Pa. d, Pg from the side. All x 13. a slight angle with the dorsoventral axis but the distal half bends sharply outwards. The costals are not quite so long as the radials; they are widely separated from each other and are not deeply incised by the axillaries. The axillaries are slightly longer than broad. The first and second brachials are of the shape shown in Fig. 6b\ the former are widely separated. The distal edges of the radials, costals, axillaries and the first and second brachials are raised into very fine spines. Syzygies occur between the third and fourth, ninth and tenth, and fourteenth and fifteenth brachials, and thereafter with intervals of two brachials between eachsyzygial pair. The fifth to eighth brachials, between the first and second syzygies, are nearly rectangular, about one-and-a-half times as broad as long (Fig. 6 c). Those between the second and third syzygies are wedge-shaped and longer than broad. The more distal brachials are longer on one side than the other, slightly longer than broad. The distal edges of all the brachials beyond the first syzygy are faintly raised and produced into short spines; they are most conspicuous on the distal brachials, but are much shorter and less conspicuous than those of E. hirsuta.
