I have observed near the middle of the fifth and four following pairs of feet a globose body, probably analogoua to the vesicles which these organs present in Apus. The only species, JS. albida, Latr., is very small, and of a whitish colour. It is found in the River of Nice. • 2. The AspiDiPHORA, Latr., [or second principal group of the Phyllopodous ^ranchiopoda] have sixty pairs of legs, all of which are furnished on the outside, near the base, with a large oval vesicle, and of Tvhidi the two anterior, much larger than the rest, and ramose, resemble anteniMe. A large §hell covers the major part of the upper side of the body, almost entirely disengaged, (shield-like,) posteriorly enjar- ginate, and bearing anteriorly, in a confined space, three simple sessile eyes, of which the two anterior are larger and lunular ; and two bivalve capsules containing the eggs, annexed to the eleventh pair of feet. Such are the characters of the genus Aptis, Scop., (forming' patt Of the genus Binoculus, Geoffrey, and Limulus, Miill.).—The body, including' the shell, is oval, broader, and rounded in front, and narrowed hehjnd, forming a tail; but if "vve remove the shell, it is nearly cylindrical, convex above, concave and divided by a longitudinal canal beneath, terninating in an elongated cone. It is composed of thirty joints, equally diminishing in size towards the posterior extremity, and which, ?VTlth the exception of the seven or eight teraiinal ones, bear the feet. The ten apterior segments aye membranous, soft, and without spines, presenting on each side a small eminence, or
