appendages ; the uropoda are asymmetrical ; the terminal segment 

 is ratfier .deeply notched at its distal end, the l,obes denticulated. 

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

 male about 3| lines (nearly 8 millim.), of right chelipede about 6^ 

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

 mUlim.). 



Two specimens -were coUeoted at Port Denison, 4 fins. (jSTo. 111). 

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



E. compressvpes resembles E. tricarinatus, Stimpson, from Japan, 

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

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

 and the more dilated joints of the first and second ambulatory legs, 

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

 the non-canaliculate carpi of the cheUpedes, &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 oflf 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 ; cornese 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 flageUa 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, and 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 being 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 (13^ miUim.), 

 of left ambulatory leg of first pair _about 7 Hnes (15 millim.). 

 A single male was obtained in the Arafura Sea (32-36 fms.).
