Distribution.—Casco Bay, Me. (Wilson). Color (preserved materi- al).—Body a uniform yel- lowish white, turning brown- ish in alcohol. Female.—Carapace orbicu- lar, wider than long, scarcely covering the second legs; posterior sinus one-fifth the length of the carapace, as wide as long; urosome longer than wide, cut one-third of its length, caudal rami basal, posterior lobes acute. Max- illary disks very large, one-fourth the width of the carapace, widely separated; each supporting rod made up of 18 segments, which are transversely lunate. Basal plate of maxillipeds slightly reentrant at the center of the posterior margin, without teeth or lobes. No flagella. Total length, 3 mm. Width of carapace, mm. Male.—Unknown. Remarks.—T h i s species may be recognized by its small size and by the absence of teeth or lobes on the basal plates of the maxillipeds. Figure —Argulus latus: a.
