CRTJSTACEA or THE MEEGUI AECHIPELAGO. 259 



times bears another mucli shorter spinule at its base, which, 

 however, is often indistinct. The upper surface of the wrist is 

 covered with two rows of hairs, and some hairs are also found on 

 its under surface. The bands are a little distorted, but otherwise 

 seem to resemble those of Gehiopsis nitida. They are as broad at 

 their proximal halves as the meropodites, and the fingers are much 

 shorter than the palm, being only half as long. The palm, rounded 

 above and below, is smooth and unarmed, but clothed with hairs, 

 some of which are arranged in longitudinal, often oblique, rows. 

 The equally long fingers cross one another with their pointed tips 

 when closed ; the mobile finger is strongly curved, very hairy, and 

 armed at the base of its inner margin with a small tooth, whereas 

 the immobile finger is nearly glabrous and minutely denticulate 

 along its inner margin. 



The second legs resemble those of G. nitida ; the meropodites, 

 which are much narrower than those of the chelipedes, are fringed 

 with long hairs along their inferior margins ; the propodites are a 

 little longer than the carpopodites, and nearly three times as long 

 as the dactylopodites, which are therefore apparently shorter 

 than those of G. nitida, but about the same size as those of 

 G. Darivinii. The upper margin of each carpopodite and pro- 

 podite, and also the under margin of the latter, is fringed with 

 long hairs, similar to those of the inferior margin of the meropo- 

 dites ; each dactylopodite is also hairy. 



The meropodites of the third pair of legs are, again, narrower 

 than those of the second pair (in the species from the Cape Verde 

 Islands, on the contrary, they are figured as being broader) and 

 nearly glabrous, being not fringed with long hairs ; the carpo- 

 podites of these legs are a little longer than the propodites and 

 somewhat hairy at their distal ends. The outer surfaces of the 

 compressed propodites are covered with two dense rows of hairs ; 

 and each of these joints is, moreover, clothed with a dense tuft of 

 hairs at the distal end of their under margin, and with a few hairs 

 along its upper margin. The hairy dactylopodites are a little 

 more than half as long as the propodites. The equally compressed 

 propodites of the fourth pair of legs are a little shorter than the 

 carpopodites and scarcely longer than the dactylopodites ; and 

 the outer surface of each is also covered with two dense rows o£ 

 hairs, as on the propodites of the third pair, and a similar dense tuft 

 of hairs is found at the distal end of the under margin of each.
