Decapod Crustacea of Bermuda. Part If. 109 



article is long, regularly tapered, subacute, proportions i : 6.5 : it 

 has about 13 transverse groups of plumose hairs ; exopod is rather 

 wide, not quite as long as third article; terminal bush of plumose 

 hairs large; fourth article also bears both plumose and simple 

 hairs. 



The smaller chela (pi. 36, fig. i ) is long-ellipsoidal, the palm 

 being a little swollen or convex above and below ; fingers are 

 shorter than palm, ratios about 1:1.2; height of palm to length 

 about i : 1.73 ; pollex is slightly curved down, and feebly denticu- 

 late at tip ; it bears three or four small clusters of hairs below, 

 and a pair near the tip; dactyl has about four small clusters of 

 hairs on outer edge and a large one close to tip. Carpus is large, 

 about as wide as long; outer angle is prominent and has a minute 

 spine ; merus is stout, breadth to length about i : 2.5, swollen 

 distally ; outer distal angle spiniform. 



Legs of second pair (pi. 36, fig. ib) have the chela elongated, 

 with the fingers slender, longer than the palm, about as 1.5: i ; 

 dactyl bears many long hairs ; pollex has five or six clusters 

 besides that near the tip ; carpus is long ; first article is about as 

 long as the sum of the others and half the palm; fifth article is 

 longer than palm : merus is stouter, somewhat enlarged along the 

 middle, width to length about i :6; about as long as the sum of 

 chela and last four articles of the carpus. 



Legs of third pair are long, especially the propodus (fig. id), 

 which bears about five spines besides one or two at the distal end ; 

 dactyl is elongated, not much enlarged proximally ; hooks are 

 nearly parallel, slender, outer one about twice as long as inner; 

 carpus has one distal spine, its length is one-half the propodus or 

 merus, which are about equal in length. . Legs of fifth pair (fig. 

 TC) are more slender, with the hooks of the dactyl more incurved ; 

 propodus bears eight clusters of stiff setae and small spinules. 



Uropods (pi. 34, fig. lu) are broadly rounded; outer lamella 

 has two nearly equal spines at the suture and a much longer articu- 

 lated spine between them. The telson (fig. it) is wide; lateral 

 borders somewhat sinuous; width of distal part to widest part 

 about i : 1.7; length about twice distal width; distal angles acute, 

 with two unequal spines, the inner one-third longer than outer; 

 four dorsal spines large, far apart; tip broadly rounded, with 

 about 22 plumose hairs. 



No. 62. Bermuda, on the coral reefs.
