PELAGIC OSTRACODS OF THE SARGASSO SEA OFF BERMUDA Conchoecia procera Miiller (Figures 16, 17) 45 Conchoecia procera Miiller, 1894, p. 228, PI. 6, Figs. 47, 48, 50-58; 1906a, p. 71, PI. XIII, Figs. 37-47, PI. XIV, Figs. 3-6; 1912, p. 72. DESCRIPTION. The shell is elongate, the height clearly less than half the length, and tapered anteriorly. The postero-dorsal corner is rounded, with a small spine, sometimes lacking in the male, which bends downwards on the right shell. The postero-ventral corner is strongly rounded, and the right asymmetrical gland is at the posterior end of the ventral margin, rather than at the ventral end of the posterior margin, as it is in C. elegans (compare Figs. 16a and 14a and b). C. procera also differs from C. elegans in ventral view, in that it has a shorter, broader rostrum, whereas C. elemns is slim in ventral view. The capitulum of the female frontal organ is pointed, with some spinules on the ventral surface (Fig. 17a); in the male it is rounded at the tip and has two rows of long fine hairs on the ventral surface (Fig. 17b, c). The principal seta. Figure 17.
