CRTTSTACEA. 267appendages ; the uropoda are asymmetrical ; the terminal segmentis rather deeply notched at its distal end, the lohes denticulated.Colour (in spirit) a very light orange-pink. Length of carapace ofmale about 3| lines (nearly 8 millim.), of right chelipede about 6|lines (14 millim.), of second ambulatory leg about 10 lines (21millim.).Two specimens were collected at Port Denison, 4 fms. (No. 111).The larger is a male, the smaller a female with ova.E. compressives resembles E. triearinatus, Stimpson, from Japan,and E. acantholepis, Stm., from Port Jackson*, in the absence of arostrum, but is distinguished from both by the nearly smooth chel®and the more dilated joints of the first and second ambulatory lefs,and from the latter also by the somewhat dilated corneaB of the eyes,the non-canaliculate carpi of the chelipedes, &c.10. Eupagurus kirkii. (Plate XXVIII. fig. C.)In this little species the carapace is scantily hairy, with thebranchial regions moderately dilated, without any indication of arostrum, and without lateral teeth, and rounded off at the anterolateralangles. The terminal postabdominal segment has its marginsminutely spinulose, is rounded on the sides, and without a mediannotch. The eye-peduncles are slender, and about as long as thewidth of the frontal margin ; corneae small and not dilated ; ophthalmicscales small, entire, with subacute apices. The basalantennal joint is very short, aud has a very small spinulo on itsouter margin ; the dorsal aciculnm of the following joint is veryslender, and reaches very nearly to the apex of the eye-peduncles ;the flagella nearly naked. The merus-joints of the chelipedes havea small spinule at the distal ends of their upper margins ; the wristsare hairy, and spinulose above, with a series of more prominentspiuules along the inner and upper margins ; the larger (right) chelais ovate, scantily hairy, rather swollen within, externally nearly flat,with a series of small spinules along its upper and lower marginsand with some obscurely indicated granules on its outer surface : thefingers are shorter than the palm, and have between them a smallhiatus at base when closed ; the lower is granulated externally ; bothare spinulose on their outer, and toothed on their inner margins.The second and third legs are of moderate length, hairy and smoothwithout spines or tubercles ; the dactyli a trifle shorter than thepreceding joints ; the fourth legs are short and imperfectly subchclate(the infero-distal lobe of the penultimate joint being butlittle developed) ; the fifth legs apparently not subchelate, thedactyli clothed with long hairs. The uropoda are, as usual, asymmetrical; the rami with a scabrous pad on their outer surfaces.Colour (in spirit) pinkish white. Length of carapace about 3.) lines(about 7-5 millim.), of larger chelipede about Gh lines (13| millim.),of left ambulatory leg of first pair about 7 lines (15 millim.).A single male was obtained in the Arafura Sea (32-36 fms.).* Proc.
