Zoological results of a tour in the Far East . ATA. Family Ebalia, heterochalaza, sp. carapace is sharply polygonal in outline and is broader than long in the pro-portion of 14 to 13. The lateral and posterior margins are coarsely granulate and Crustacea Decapoda and Stomatopoda. 251 the postero-lateral border is divided into thirds by two clusters of enlarged andprominent tubercles (text-fig. 7). Thegrooves and depressed portions of thecarapace are smooth and the elevatedparts tubercular. The sculpture of thedorsum is much as in E. diadumena, Al-cock, but the grooves are not so elevations on the gastro-cardiac, in-testinal and branchial regions are coarselygranulate and in the middle of the twoformer are several very large upstandingtubercles of a pearly appearance and ofa size much greater than those on anyother part of the carapace. The gastro-cardiac and intestinal elevations are im-perfectly separated from one anotherby a transverse furrow ; the granules on. Fig. 7.—Ebalia heterochalaza, sp. nov. them are very dissimilar in size. The front is deeply hollowed in the middle line ; itsantero-lateral portions bear numerous fine denticles. The anterior margin is practicallystraight, the edge of the epistome being visible in dorsal view. The hepatic facetis well defined ; its lower border is excavate posteriorly and is edged with excep-tionally large tubercles. Its upper margin is defined by smaller tubercles whichform a cluster near the middle of its length. The posterior limit of the facet is markedon either side by a large tubercle and the margins between these tubercles andthose that define the widest portion of the carapace are straight and posteri-orly divergent. The posterior margin is narrow, slightly sinuous, a little promi-nent at the middle point and with protruding lateral angles. The lower sur-face of the carapace, on either side of the outer maxillipedes, is conspicuouslygranular. T
