Show 292 MR. G. S. BRADY O.N EUROPEAN CYPRIDINID.F. [Apr. 4, and third joints long, the second much shorter, the rest short and subequal: secondary branch in female indistinctly jointed, setose ; in the male long, three-jointed, cheliform. Mandibular feet nearly alike in both sexes ; in the female armed, as in the female Bradycinetus, with mandibuliform processes and spines, in the male bearing on the basal joint a small tubercle with two short hairs ; second pair of jaws in the female armed with mandibuliform processes. Eyes as in Bradycinetus. A S T E R O P E * (Philippi). Shell subcylindrical, beak not at all produced. Upper antennae as in the preceding genus. Second joint of the natatory branch of the lower antennae in the male elongated, in the female scarcely longer than the succeeding joints; secondary branch in the male robust, subchelate; terminal joint slender, curved upwards ; in the female simple, triarticulate, last joint setiform. First maxilla consisting of a broad subquadrate or crescentic lamina, densely clothed on its distal margin with long bristles ; second swollen at the base, narrowed at the apex, where it bears six plumose setae, basal portion setose along its convex margin ; third maxilla narrow, elongated, setose along the inner margin. Abdominal laminae broad and short, subtruncate at the extremity. 1. CYPRIDINA NORVEGICA, Baird. Hab. Norway, Shetland. 2. CYPRIDINA MESSINENSIS, Claus. Hab. Mediterranean. 3. BRADYCINETUS BRENDA, Baird, sp. (Plate XXVI. fig. 6.) Cypridina brenda, $, Baird, 1850. Cypridina globosa, £ , Lilljeborg, 1853. Bradycinetus globosus, $ , G. O. Sars, 1865. Bradycinetus brenda, $, Brady, 1868. Asterope grcenlandica, _T, Fischer, 1854. Two specimens of a form exactly conforming to Fischer's description oi Asterope grcenlandica occurred in M . de Folin's dredgings from the Fosse de Cap Breton. The shell differs from that of the female B. brenda in being less tumid and slightly more angular in outline; it is also quite smooth and free from villosity. The swimming-filaments of the upper antennae are a little longer than those of the female, and more decidedly plumose. There is also a stout auditory ••eta; the natatory branch of the lower antenna is nearly alike in both sexes, but the secondary branch in the male is largely developed and triarticulate. The mandibular foot is much elongated (Plate X X V I . fig. 6), and bears on its basal portion a large and strong * This genus might perhaps with more propriety (on account of the widely different structure of the maxillae) be made the type of a distinct family. It is identical with Cylindroleberis (Brady), a fact of which I was not aware when that name was proposed. |
