178 " THETIS " SCIENTIFIC RESULTS. 



few short hairs ; larger flagellum consisting of six articuli, the 

 first stout, glabrous and a little broader than long ; the second 

 and third subequal, twice as long as broad, each of which bears 

 a dense tuft of long hairs ; fifth joint narrow, and equal in length 

 to the four preceding ; sixth short, with an apical tuft of long 

 setfe. 



Peduncle of second antenna 0-7 mm. long ; first joint stout, with 

 a slight lobe on its inner distal angle. 



Acicle subacute, three times as long as broad, reaching to the 

 end of the short second joint, it bears a short spinule at its outer 

 apical angle ; third joint not quite equal to the first and second 

 combined. Flagellum 1'6 mm. long, with twelve articuli, each 

 of which bears four or five short hairs at the apex. 



Chelipedes equal, the left 2"5 mm. long. Merus joint com- 

 pressed, one-third longer than deep. Upper border carinate, 

 armed with six very faint denticles, from which 

 arise an equal number of short setse ; inferior 

 border similar to the upper but shorter ; outer 

 Left helipede x . j^Q^.^jg^. angular : lateral and inferior surfaces

smootii. 



Carpus short, a little compressed, about equal in length to the 

 depth of the merus ; upper border arched and subacute ; lower 

 border extremely short ; outer distal margin with a slightly 

 thickened rim, which is bounded posteriorly by a narrow groove ; 

 surfaces with a few scattered hairs. 



Hand short, compressed, longer than the merus ; palm deeper 

 than long ; upper and lower borders rounded, equal in length ; 

 both, as well as the outer surface and the upper distal margin, 

 bearing a few short setiferous denticles. 



Fingers longer than the palm, slight, hairy and corneous at the 

 tips; the upper is acute and bears two small denticles on its inner 

 margin; the lower is obtuse and somewhat excavated, its inner 

 margin has one large denticle situated about the middle. 



Second pair of legs perceptibly stouter and longer than the 

 third, about 3 "9 ram. in length ; ischium joint twice as long as 

 broad; merus compressed, twice as long as the ischium; upper and 

 lower borders thin, with a few scattered hairs; carpus deeper than 

 wide, its lower border equal to the ischium in length ; upper 

 Vjorder rounded, with a faint transverse impression near the distal 

 end, from which arise several stiff setae; propodus equal to the 

 tarsus, borders rounded, external surface with three or four rather 

 ill-defined ridges disposed longitudinally. 



Tarsus a little curved and compressed, tapering from the 

 proximal third to the acute, dark brown, horny claw, lower 

 border armed with five or six spinules which are strongly inclined 

 forward towards the extremity. The third leg differs from the 

 second in having the ischium joint broader than long.
