254 the end of the caudal segment. Moreover, some well-marked differences are found in the structure of the several appendages, the 1st pair of legs in particular, being very different, exhibiting a similar robust form to that found in Desmosoma armatum. The male is less different from the female, than is usually the case in the species of Eugerda and Desmosoma. In all the specimens examined the inferior antennae were broken off, and I have thus been prevented from examining the structure of these appendages. Occurrence. This form was also taken during the Danish Expedition, and in the very same place, where Macrostylis longiremis and Desmosoma angustum occurred. Eugerda lateralis (Han sen). (Suppl. PI. IV, fig. 1). Desmosoma laterale, Hansen MS. Specific Characters. Body of female rather slender and elongated, resembl- ing that of E. tenuimana, though having the posterior fully developed. Cephalon of the usual form. 1st segment division of mesosome less of mesosome well developed, and, like the 2 succeeding ones, having the lateral parts curved anteri- orly and obtusely pointed; 4th segment considerably narrower than the preceding ones, and transversely truncated at the extremity; 5th segment quadrangular in form, nearly twice as broad as it is long, and having the anterior corners obtuse. Caudal segment comparatively large, oval pyriform, with a small tooth-like projection on each side beyond the middle, tip narrowly rounded. Inferior antennae not much elongated, scarcely exceeding in length the cephalon and 2 anterior segments of mesosome combined, flagellum shorter than the peduncle, and com- posed of 6 articulations only. 1st pair of legs very strongly built, with the joints considerably dilated, meral joint with one, carpal joint with 2 very strong spines inside, propodos oblong, tapering d^tally, with a row of very small spinules inside; the 3 succeeding pairs rapidly decreasing in size, carpal joint moderately expanded and carrying inside 4 slender spines, outside 3 bristles. The 3 posterior pairs of legs rather poorly developed, and of a structure similar to that in the 2 preceding species. Uropoda with the outer ramus somewhat larger than in E. coarctata, though scarcely attaining half the length of the inner. Length of adult female about 2 mm. Remarks. This is another new species, first recognised as such by Dr. Hansen, and referred by him, like the preceding species, to the genus Desmosoma.
255 It is easily distinguished from the 2 preceding species both by the general form of the body, and by the structure of the legs. Occurrence. Only 2 or 3 specimens of this form were found during the Danish Expedition, and on the very same place (Stat. 460), where the preceding species occurred. of Copenhagen). Page 143.
