Epimera are present onall the segments except the first. The firsttwo are narrow, with rounded extremities, and do not extend beyond the posteriormargin of the segments. The two following have the posterior extremities acutelyproduced and extending just a little beyond the postlateral angles. The last twoare also acutely produced, and they extend some distance beyond the postlateralangles of the segments. The first segment of the abdomen is entirely concealed; the three following segmentsare subequal; the fifth is a little longer than any of the preceding; the sixth or terminal. a bFig. 7.—Alcirona tuberculata. a, AbdomenX 9f; b, first leg of male, X 20J-. alt does not seem necessary for the reasons given to change the family name to Corallanidse, as Steb-bing has suggested, nor to change Cirolanidse to Eurydicidae nor Arcturidse to Astacillidae.

Its dorsal surface has two parallel rows of four small tubercles, onerow on either side of the median line. The outer branch of the uropoda is produced toan acute extremity and does not reach beyond the extremity of the abdomen; the innerbranch is about twice as wide, more rounded at the extremity, and extends just a littlebeyond the extremity of the abdomen. Both branches are fringed with hairs andfurnished with spines. The first three pairs of legs are prehensile and have the mer
