CRUSTACEA. 267 



appendages ; the uropoda are asymmetrical ; the terminal segment 

 is rather deeply notched at its distal end, the lobes denticulated. 

 Colour (in spirit) a very light orange-pink. Length of carapace of 

 male about 3| lines (nearly 8 millim.), of right chelipede about. (>.', 

 lines (14 millim.), of second ambulatory leg about 10 lines (21 

 millim.). 



Two specimens were collected at Port Denison, 4 fms. (Xo. 111). 

 The larger is a male, the smaller a female with ova. 



/-J. compressipes resembles E. tricarinatus^ Stimpson, from Japan, 

 and E. acantTiolepis, Stm., from Port Jackson *, in the absence of a 

 rostrum, but is distinguished from both by the nearly smooth cheke 

 and the more dilated joints of the first and second ambulatory leo-s, 

 and from the latter also by the somewhat dilated corneae of the eyes, 

 the non-caualiculate carpi of the chelipedcs, &c. 



10. Eupagurus kirkii. (Plate XXVIII. fig. C.) 



In this little species the carapace is scantily hairy, with the 

 branchial regions moderately dilated, without any indication of a 

 rostrum, and without lateral teeth, and rounded off at the antero- 

 lateral angles. The terminal postabdominal segment has its margins 

 minutely spinulose, is rounded on the sides, and without a median 

 notch. The eye-peduncles are slender, and about as long as the 

 width of the frontal margin ; corneae small and not dilated ; oph- 

 thalmic scales small, entire, with subacute apices. The basal 

 antennal joint is very short, and has a very small spinule on its 

 outer margin ; the dorsal aciculum of the following joint is very 

 slender, and reaches very nearly to the apex of the eye-peduncles ; 

 the flagella nearly naked. The merus-joints of the chelipedes have 

 a small spinule at the distal ends of their upper margins ; the wrists 

 are hairy, and spinulose above, with a series of more prominent 

 spinules along the inner and upper margins ; the larger (right) chela 

 is ovate, scantily hairy, rather swollen within, externally nearly flat, 

 with a series of small spinules along its upper and lower margins 

 and with some obscurely indicated granules on its outer surface : the 

 fingers are shorter than the palm, and have between them a small 

 hiatus at base when closed ; the lower is granulated externally ; both 

 are spinulose on their outer, aud toothed on their inner margins. 

 The second and third legs are of moderate length, hairy and smooth 

 without spines or tubercles ; the dactyli a trifle shorter than the 

 preceding joints ; the fourth legs are short and imperfectly sub- 

 chelate (the infero-distal lobe of the penultimate joint bein°- but 

 little developed) ; the fifth legs apparently not subchelate, the 

 dactyli clothed with long hairs. The uropoda are, as usual, asym- 

 metrical ; 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 6| lines (131 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.).
