Abstract
1. Bairdia (?) ellipsoidea, G. S. Brady, MS.
Carapace ovato-trigonal; somewhat compressed; highest (broadest) in the anterior third. Valves smooth, thick; right valve the largest, overlapping the other on the dorsal and ventral borders, and marked with a furrow within each of those edges for the reception of the fellow valve. Length 1/48 inch. Four specimens.
This somewhat resembles Bairdia ovata, Bosquet, sp. (‘Mém. Commission descr. Carte Géol. Néerlande,’ vol. ii. p. 73, pl. 5. Fig. 6), and probably belongs rather to Pontocypris than to Bairdia, both of which are marine members of the family Cypridœ. See G. S. Brady's “Monograph of the Recent British Ostracoda,” Linn. Trans. vol. xxvi. p. 360, &c.
2. Cythere Moorei, G. S. Brady, MS.
Carapace tumid; egg-shaped, with terminal lipsa nd flattened ventral surface; somewhat like a peach-tone in shape and ornament. Surface of the valves reticulate; the meshes rather coarse on the middle, but having a tendency to become longitudinal and parallel on the sides and towards the extremities.
Length 1/32 inch. Three specimens.
In general form this approaches C. striatopunctata (Römer) and C. concentrica (Reuss); but the reticulation differs. It takes its name after Mr. Charles Moore, F.G.S., one of the most enthusiastic of geologists, and a successful among Lias fossils.
3. Cythere Blakei, sp. nov.
Carapace oblong, subcylindrical, with marginal lips at the ends, obliquely rounded in front, contracted and rounded behind, somewhat compressed dorsally at the median third. Surface rough, with faint
