48 CRUSTACEA MALACOSTRACA VIII (AMPHIPODA IV) with a single medio-dorsal lobe and a pair of ventrolateral lobes as in several other genera, but without limbs. § unknown. Genus: Thorina n. gen. Pereiopods 3-4 missing, the other pairs normal. Two pairs of gills (on third and fourth segments). Antenna 1, no accessory flagellum. Antenna 2, flagellum 2-articulate. Mandible with molar longer than first; flagellum about as long as peduncle, 16-arti- culate; no accessory flagellum. Antenna 2 as long as peduncle of antenna 1. rather narrow: flagellum short, 2-articulate. Pereiopod 1 about as in Protellina ingolfi (fig. 35), but the hand is somewhat narrower. Pereiopod 2, second and third joints each terminate in a spine-like process on fore-margin; hand very powerful, oval, with upper edge boldly curved and terminating in front in a small conical projection; palm evenly curved, defined by a triangular lobe tipped with a small spine, and with two

Of the two pairs of marsupial plates the first pair is ciliated both on fore and hind margin, the second pair only at the lower corner. Genotype: Thorina spinosa n. gen. n. sp. 358.

Description of ovigerous $, 10 mm (Fig. 37). Body rather slender. First segment very short, not longer than head, and in length only about one third of segment 2. Segments 3-4 subequal in length, but longer than second segment; 5th segment a trifle longer than 4th; 6th and 7th segments short. Head and first segment are dorsally smooth; 2nd and 4th to 6th segments have two dorsal spines each, 3rd segment has 3, and 7th segment is dorsally smooth; all the dorsal spines are unpaired. Third and 5th segments have a pair of veutro-lateral spines near fore end. and there is a short spine above base of all pereiopods (except first pair) and gills; besides there is a pair of rather short ventro- lateral spines in front of base of pereiopod 6. Eyes could not be traced. Antenna 1 a trifle longer than head L 3 first segments; second joint the longest, third joint a trifle small teeth near finger hinge; dactylus very strong, a trifle shorter than palm. Pereiopods 5-7 are slightly increasing in length from no. 5 to no. 7; pereiopod 5 is much more slender than prp. 6-7, but of a similar shape; on fore margin of 4th-6th joints of these three pairs of legs there are very slender spines, not short heavy spines as in Protellina ingolfi (fig. 35). The gills are narrow. <§ unknown. Genus: ^Eginella Boeck. 359. /Eginella spinosa Boeck (Chart IX). MgineUa spinosa G. 0. Sars, Crust, of Norway, vol. 1, 1895, p. 653, pi. 235 fig. 1.
