—CRTJSTACEA. 549the lobes but little prominent. The postabdomen has all the segments,except the last, coalescent. The inferior surface of thecarapace is closely granulated. The exognath of the outer maxillipedcsis rather narrow, with a straight outer margin, and does notreach to the distal end of the merus-joint of the endognath. Thechelipedes are rather small, and arm, wrist, and palm arc closelygranulated, but otherwise unarmed ; palm not twice as long as thewrist, rather turgid : fingers about as long as the palm, slender, andmeeting along their inner edges. Colour (in spirit) pinkish. Lengthof carapace barely 2 lines (4: millira.).This specimen is distinguished from all of the species of this genusAvith which I am acquainted by the evenly-granulated carapace andthe number and disposition of the spines of the lateral and posteriormargins. If the characters should prove constant, I would proposeto designate it as Arcania duodecims/iinosa.Arcania pulchdla *, from the Fijis, which is evidently verynearly allied to it, has the lateral margins armed (on each side)Avith about seven teeth, the front nearly straight, the regions of thecarapace strongly mammillated.71. Ebalia granulata {Rllppell)'^.Since the original diagnosis is very brief, I append the followingdescription :The body and legs are everywhere covered with numerous veryclose-set and crowded perliform granules, which are largest on thepostabdomen and on the merus-joints of the chelipedes ; the caraliaceis nearly circular in outline (not rhomboidal), but a littlebroader than long, moderately convex, the gastric and cardiacregions defined by faintly indicated lateral sulci. The front is slightlyconcave, and projects less than the buccal cavity, so that the outermaxillipedes are just visible in a dorsal view ;the hepatic regionsare prominent, the lateral margins are slightly sinuated, but notlobate or toothed. The postabdomen (of the female ") has all thejoints, except the first two and the last, coalescent. The eyes areclosely set in the nearly circular orbits ; the small antennte enterthe inner orbital hiatus ; the merus-joints of the outer maxillipedesare shorter than the ischium-joints ; the rather narrow exognathshave a straight outer margin, and do not reach to the distal endsof the merus-joints ; the chelipedes (in the female) are rather small,the merus-joint or arm has its inner distal angle somewhat producedand rounded, but is not toothed ; carpus small, rounded ; palmlittle longer than the carpus, rather turgid ; the fingers are longerthan the palm, meet along their inner edges, and are slightly incurvedat the tips. The ambulatory legs are very slender ; thedactyli bear a minute terrainal claw. Colour (in spirit) pinkish.Length of carapace about 2h lines (5 millim.) ; of chelipede (of thefemalej about Klines (nearly 7 millim.).* Ebalia pulchdla, Jouni. Ma?.
