A. E. Verrill — Decapod Crustacea of Bermuda. 445 



of the chelipeds and legs are seen to be covered with a reticulation 

 of narrow, bright red lines, which generally, also, surround and mark 

 out the paler colored tubercles and spinules, but they may also f oi-m a 

 network of small polygons on the smooth surfaces. When the chelae 

 and tubercles are red, as in some of the larger specimens, these lines 

 become dark red, but are less conspicuous, especially on the outer 

 surface, where the appressed hairs between the tubercles conceal 

 them. 



The ambulatory legs are usually crossed by three or four wide, 

 rather conspicuous bands of red, one on each segment, or the red 

 color may sometimes predominate, and then the bands are yellow 

 or orange, on a red ground-color. 



A specimen of medium size, from Dominica, has the carapace 31™™ 

 long; anterior portion, 13™™; bi'eadth of anterior part, 12,5'"™; of 

 posterior part, 26™™ ; length of eye-stalks, 8™™ ; length of larger 

 chela 22™™; height, 13^'™; length of right chela, 13™™; height, 8™™; 

 propodus of 2d left ambulatory leg, 13™™ long; 7.5™™ wide; dactylus, 

 20™™ long; 5™™ wide at base. 



A larger specimen has the left chela, 25™™ long; 15™™ high; 10™™ 

 thick; palm above, 13™™; dactylus, 13™'".

The carapace of a small specimen preserved for a short time in 

 formol is pale yellow, with a bright purple median area anteriorly, 

 and a branchial patch of the same on each side, and bands of the 

 same color at the bases of the legs and on the middle of the eye- 

 stalks. The chelipeds are orange, finely reticulated with bright red 

 lines, the reticulations enclosing the whitish tubercles. The second 

 leg on the left side is larger and has on its outer side a median row 

 of bright purple rounded tubercles on the two distal segments, and 

 an outer sublateral row of smaller ones of the same color; the four 

 distal segments of the legs have each a wide band of dark red.
