. The Annals and magazine of natural history; zoology, botany, and geology. Natural history; Zoology; Botany; Geology. Tecticeps convexus. a, head, x 6i; b, abdomen and last thoracic segment, x 2§. one joint the length of the first pair of antennae. Both pairs of antennae are disposed to lie concealed under the broad epimeral plates of the thoracic segments. The thoracic segments are subequal in length. The first segment has its antero-lateral angles produced around the anterior portion of the head, forming a broad phite at the side of the segment. The epimera are almost twice as broad as long ; those of the fifth segment extend downward, with the anterior margin straight, making the length and breadth about equal, and forming almost square epimera; in the epimera of the sixth and seventh segments the anterior margins are in tlie same direction as the posterior margins, which extend downward. The first segment of the abdomen has three suture-lines, and its posterior margin is produced in two small points, one on either side of the median line, about equidistant from it and the lateral margin of the segment. The terminal seg- ment is widely rounded posteriorly. The inner branch of the uropoda is of nearly equal width throughout its length and is rounded at its extremity ; the outer branch is slender and sharply pointed. Both branches are of nearly equal length and neitlier extends beyond the tip of the abdomen. The first pair of legs have the propodus dilated and the dactylus reflexible. The propodus is large and oval in shape. ]n the legs of the second pair the propodus is irregular in shape, sometimes dilated with reflexible dactylus, and some- times simple. The legs of the other five pairs are similar in structure, ambulatory, and show a gradual increase in length. A number of individuals were found at Monterey Bay, California, and sent to the National Museum by Mr. Heath, who gives the following notes of their habits:— " They were taken by the Chines
