_Lepas anatifera_ Linnæus. Fig. 4 This is a fairly abundant goose barnacle, found in holdfasts of kelp and occasionally on driftwood and floating objects. The size varies from a few millimeters to almost an inch in length. The distinguishing characters are the very fine striations on the valves, the presence of an umbonal tooth on the right scutum, and the proximity of the base of the carina to the scutum. The valves are a delicate pale blue color and the peduncle a deep purplish brown. [Illustration: Figure 5] _Lepas fasciculatus_ Elis and Solander. Fig. 5 Two specimens were found by Mr. Lichti upon the beach at Green Bay, Laguna Beach, in September of this year. Others have been collected from the Laguna region. It is a light pelagic form, with paper-like plates and angularly bent carina, with a prominent umbo. Notes on the Eggs of Some Laguna Beach Invertebrates P. A. LICHTI During the past summer a large number of species and individuals were examined for eggs. Some of these fragmentary notes may be of use to others who may carry the study further. The serpent stars were not especially studied for the eggs, but during July several hundred were collected from various places. These were mostly of one species. About one-third of these contained well developed ova. On July 14th and 20th, six individuals of the genus _Ophiothrix_ deposited eggs in the aquarium jars. During August three out of twenty specimens had ova well developed, many may have been young. Comparatively few female sea urchins were found. Out of 50 individuals opened, 36 were males, six females, and the rest young. Miss Wang also found that the males were more numerous than the females as they were collected, four to one. Miss Wang was able to keep the sperm alive for 96 hours in the laboratory before we had running salt water. In the common shore goose-neck barnacle _Mitella_, ova and segmentation stages were found during the summer. The common rock crab, _Pachygrapsus_, was examined many times during July and very few adult females were without eggs. During the same day mature ova and advanced embryos were found. August 10th, about half the females were without eggs. On September 4th, about two-thirds were without eggs. The early summer seems the more active spawning season. A live female deeper sea crab, _Loporhynchus_, was caught on June 25th. The enormous mass of eggs was unsegmented and failed to segment in the laboratory, although the animal was kept alive for some time. On July 20th, another female was caught, the embryos were well advanced and it was possible to see the heart beat under the microscope. They lived only a few hours.
