CRUSTACEA. 209usual, nearly quadrate, with the anterior margin straight, and hasthe next joint articulated with it at its antero-internal angle. Thechelipedes are subequal and moderately robust ; the merus or armshort, trigonous, its upper margin distally armed with three or fourteeth ; carpus or wrist very distinctly tuberculated on its upper andouter surface ;palm with only three or four tubercles appearingthrough the pubescence at base ; fingers little shorter than the palm,pubescent, except at and near the tips, which are acute, regularlydenticulated, and closing along their inner margins. The ambulatorylegs are slender, rather long, and densely pubescent ; the merusjointshave a tubercle at their distal, and the carpus-joints one attheir proximal ends. Colour cinereous grey. Length of the singlespecimen examined (a female) about 3g lines (nearly 8 millim.),breadth about 4^ lines (nearly 10 millim.).This specimen was dredged in the Arafura Sea, at a depth of32-36 fms. (No. 160).In the structure of the antennae and orbits (see fig. h) thisspecies resembles Euxanthus and Liagore, but the form of thestrongly tuberculated and densely hairy carapace seems to precludeits being assigned to either of these genera. In these particulars andin the slender ambulatory legs it more closely resembles Halunedefragifer, De Haan ; and I have accordingly assigned it to the genusHaliiiiede, although with some uncertainty, since De Haan in hisdescription does not say whether the basal antennal joint enterswithin the inner orbital hiatus or is merely in contact with the subfrontalprocess ; if the latter, our new species will, I think, have tobe made the type of a new generic division,39. Actaea rlippellii (Kranss).To this species must, I think, be referred a small and very hirsutefemale from Port Molle, 14 fms. (No. 93), and a somewhat largerfemale with very prominent and distinctly granulated areolae onthe carapace, obtained at Port Denison, 4 fms. (No. 122), firstcollection ; also two small females from Thursday Island, 3-4 fms.(No. 177), second collection.There are specimens in the British-Museum collection from theMauritius {Old Collection) and Malaysian seas (coll. Dr. Bleel-er);perhaps also a specimen from Norfolk Island, 23 fms. (H.M.S.'Hercdd '), belongs here.I have already, in my report on the late Dr. Bleeker's Malaysiancollection*, given the leading references to the synonyma of Actcearuppellii.40. Actaea areolata, Dana"?To this species are very doubtfully referred several specimens ofboth sexes from Port Molle, obtained either on the beach (Nos. 95,103) or at a depth of 14 fms. (No. 93).
