250 Page 122. Add the following species: Macrostylis longiremis (Meinert). (Suppl. PI. H, fig. 1). Vana longiremis, Meinert, Crustacea malacostraca (from the cruise of the steamer ,,Hauch"). p. 195, PL H, figs. 6373. Specific Characters.- Very like M. spinifera, but, on a closer examination, easily distinguishable by the somewhat different shape of the caudal segment, which is not nearly so much produced at the end, between the insertion of the uropoda. The 3rd pair of legs with the ischial spine less curved, and distinctly bidentate at the tip. The 3 posterior pairs of legs comparatively less slender than in the type species. Uropoda not attaining the length of the caudal segment, and having the distal joint nearly half as long as the proximal one. Length of adult female 2Ya mm. Remarks. It is Dr. Hansen who has called my attention to the fact that the form described by Prof. Meinert as Vana longiremis does not exactly agree with Macrostylis spinifera, to which I have formerly adduced it as a syno- nym. Through the kindness of that distinguished zoologist, I have received several specimens of the Danish form, and a closer examination of these has indeed convinced me that it ought to be regarded as a distinct, though very closely allied species. The differences between the 2 species may be easily seen on a comparison of the figures given on the accompanying plate, with those on PI. 51. Occurrence. This species has certainly not yet been found off the Nor- wegian coast; but as it occurred rather frequently in one Station (460) lying in the Skagerak at rather a long distance north of Skagen, it may with almost equal right be referred to the Norwegian fauna as to the Danish. In all probability it will, on a closer investigation, be found to exist off the coasts of both countries. Page 127. Add another species: Desmosoma angustum, Hansen, MS. (Suppl. PL H, fig. 2, PL IV, fig. 2). Specific Characters. Body of female very slender and narrow, being more than 6 times as long as it is broad, and somewhat moniliform, with the segments sharply marked of from each other. Cephalon of moderate size, distinctly notched
_25J_ on each side, and having the frontal edge broadly rounded. The 3 anterior segments of mesosome of nearly same size and shape, with the lateral parts slightly expanded and curved anteriorly, each terminating in a blunt corner; 4th segment considerably narrower, subquadrate in outline, and somewhat constricted in the middle. Posterior section of mesosome exceeding the anterior in length, its 1st segment much longer than any of the other segments, but rather narrow, with the anterior corners rounded off. Caudal segment narrow oblong, without any lateral notch, tip narrowly rounded. Inferior antennas comparatively short, not attaining the length of the anterior division of the body, flagellum somewhat exceeding half the length of the peduncle, and composed pair of legs rather strong, meral and carpal joints dilated, of 9 articulations. 1st and each armed inside with 3 strong spines, propodos narrow, sublinear, unarmed; 2nd pair still larger and of a very similar structure, carpal joint armed inside with 4 strong spines, meral one with only 2 such spines; the 2 succeeding pairs rapidly decreasing in size, and likewise spinous inside. The 3 posterior pairs comparatively feeble and imperfectly natatory, carpal joint but slightly dilated, and carrying inside only 2 or 3 slender spines. Uropoda scarcely attaining half the length of the caudal segment, and of the structure characteristic of the genus. Adult male somewhat less slender than the female, and having the frontal part of the cephalon considerably more produced, and distinctly insinuated at the tip. The 4 anterior segments of mesosome each with the lateral parts produced to a short incurved spine. Posterior section of mesosome comparatively broader than in the female, its 1st segment nearly quadrate in outline, with the anterior corners tipped by a small denticle. Caudal segment likewise broader than in female, and more evenly rounded at the i tip. Length of female about 2 mm., of male iVa mm. Remarks. This is a very distinct species, easily recognizable from any of the other known species of the genus, both by the general form of the body and by the structure of its several appendages. It has been provisionally named by Dr. Hansen as above, and the specimens were kindly and description. sent me for examination Occurrence. The specimens were taken during the Danish Expedition in the very same place (Stat. 460) where Macrostylis longiremis occurred, the depth being 125 fathoms.
