(_Contribution from the Zoological Laboratory of Pomona College._) A New Pseudoscorpion from California NATHAN BANKS Professor Hilton recently sent me a pseudoscorpion taken on the beach near water, which proves to belong to the genus _Atemnus_. Our common Florida _Atemnus_ also occurs on the sea beach. The Californian species differs from the Florida form in having a larger hand and more hairy body. _Atemnus hirsutus_ n. sp. [Illustration] Pale yellowish; cephalothorax a little longer than broad behind, narrowed in front, sides slightly sinuate, clothed with short, simple bristles; mandibles not one-third the length of the cephalothorax, with a short stylet; abdomen elongate, cylindrical, the segments with apical and preapical rows of simple bristles; legs rather large, with many simple bristles, all showing trochantins. Pedipalpi large, clothed with many fine simple hairs and bristles; the trochanters bituberculate behind near tip; the femur about as long as the width of the cephalothorax, of nearly equal width throughout; the tibia about as long as femur, a little broader beyond the middle, about equally convex on each side; hand extremely broad at base, barely shorter than the tibia; fingers as long as the hand, much curved, each with some tooth-like granules and a fine toothed ridge on the apposed sides. From Laguna Beach, California, ten feet from the ocean. (Hilton.) A Nebalia from Laguna Beach R. LA FOLLETTE Among the many marine forms collected and studied at Laguna Beach this summer were several Nebalia, which were taken by Mr. Lichti from a holdfast cast up on the beach. A specimen was sent to the National Museum at Washington, where it was classified as _Nebalia bipes_ O. Fab. A brief description of the animal will be given in this paper. _Nebalia bipes_ O. Fab. (Plate I, Fig. 1) belongs to the order Phyllocarida, which is the linking order between the Branchiopoda and Copepoda on one hand and the Schizopoda and Decapoda on the other. There are only three genera, and the commonest of these is _Nebalia_. So far as I know this form has never before been reported from this region. The specimen here described was 9 mm. in length and a whitish flesh color. It was transparent in the living animal. The body is divided into a head, thorax and abdomen, having the normal malacostracan number of segments, except the abdomen, which is made up of eight, the last bearing caudal styles. There is a bivalved cephalic carapace extending back to the fourth abdominal segment and terminating in front in a movable rostrum. The eyes are large, round and raised on movable stalks.
