Habitat. — Station 308, off Tom Bay, Patagouia ; deptli, 175 fathoms; bottom, blue 

 mud. Many specimens Avere obtained in this locality. 



Station 315, Falkland Islands; depth, 5 to 12 fathoms; bottom, sand, graveh A 

 young specimen, still retaining the red banding of the ambulatory limbs noted by 

 White. 



The Challenger examples all belong to the above-named new variety, which is 

 characterised by the prominence of the ridges on the hand of the larger chelipede, 

 the inner being especially raised ; towards the centre there is a conspicuous bifurcate 

 A-shaped ridge extending from the base of the immobile fmger to the carpo-propodal 

 articulation. In addition to the typical form Miers has described a variety which he 

 terms var. latimanus, distinguished by the breadth of the hand and the prominence of 

 its ridges. 



Eupagurus coviptus is onl}' known as an inhabitant of the Patagonian region. 



Eupagurus constans, Stimpson (PI. VI. fig. 8). 



Eupagurus co7istan$, Stimpson, Proc. Acad. Nat. Sci. Philad., p. 86, 1858. 

 Habitat. — Off Yokohama, Japan. 



Originally taken by Stimpson in the Bay of Hakodadi, Yedo Island, at a depth of 

 4 fathoms, on stony ground. The front possesses three prominent acute projections, the 

 mesial more produced than the two lateral. The chelipedes are elongated and of large 

 size, the terminal joints armed with conical spines and setigerous tubercles ; the right 

 ischium possesses a prominent internal spine, and the merus has several spinules on its 

 upper and distal border ; the carpus and propodus have the conical spines arranged in 

 marginal and central series, with the bristle-tufted tubercles scattered between ; the 

 dactylus of the left chelipede is devoid of spines. The ambulatory limbs are com- 

 paratively smooth. In the allied Eupagurus spinulimanus, Miers, from New Zealand, 

 the median frontal tooth is almost obsolete, the spines on the hand of the larger chelipede 

 are arranged in two rows, and the carpal joint of the second pair of ambulatory limbs is 

 spinose on the upper surface.
