Descriptions of a new genus and forty-six new species of crustaceans of the family Galatheidae, with a list of the known marine species

Abstract

SOME NEW DEEP SEA CRUSTACEANS-BENEDICT. 245 in species having an armature of v^ery small spines, as if chance conditions more easily pushed aside the less emphatic character. In old specimens of some species (and perhaps of all) the spines have a tendency to become blunted or even aborted, the chelipeds to become elongated, and the lingers to be separated })y a hiatus. The relative lengths of the supraocular spines are as a rule uniform, and, in connection with others, furnish a very good character. The size and arrangement of the spines of the carapace and also of the abdomen, if armed, are important. Correlated with other characters, the width of the lines of the carapace, the length and character of the cilia, and the size of the granules are of value in determining species. Some of the species in the U. S. National Museum are represented by but few specimens or even single individuals. In other cases the representation is greater. Large numbers of Miiuida iris A. Milne-Edwards, were taken on the tile-fish grounds during the first years work of the U. S. Fish Commission steamer J^ish Ilmvk. So numerous in fact was this Munida that it gave character to the ground. Yet two years later, when the Albatross went over the same ground, the hauls of the beam trawl showed that this species, formerly so abundant, was wanting. Three degrees farther south, however, in latitude 87°north, numerous specimens were found. I NO. 1311. SOME NEW DEEP SEA CRUSTACEANS-BENEDICT. 247 e. Palm narrow. /.

Especies de <i>Galacantha</i> y <i>Munidopsis</i> (Crustacea: Decapoda: Anomura: Galatheidae) de las aguas profundas frente a Taiwan, con la descripción de dos nuevas especies

“…On the other hand, more species probably still await discovery in Taiwan. For example, M. antonii (Filhol, 1884), M. cylindropus Benedict, 1902 andM. subsquamosa Henderson, 1885 have been reported from both Japan and other Indo-West Pacific localities (Baba, 2005), but not yet from Taiwan.…”

<i>Uroptychodes</i>, new genus of Chirostylidae (Crustacea: Decapoda: Anomura), with description of three new species

“…The only available record for crinoid-chirostylid association is Uroptychus capillatus Benedict, 1902 and a comatulid Crinometra brevipinna (Pourtalès) from Bahamas (Rice and Miller, 1991 …”

“…O gênero Munida apresenta duas características ecológicas marcantes: sintopia (LAIRD, et al, 1976) e gregarismo (BENEDICT, 1902). Isto é, diferentes espécies podem habitar áreas muito próximas (sintopia).…”
