surface bears a row of similar teeth. In the distal half of 

 the joint the outer edge becomes fairly narrow and sharp. 



The left cheliped is much smaller than the right, reaching 

 usually only to the middle of the propodite of the latter. The 

 merus and carpus are strongly compressed laterally. There 

 is a row of strong teeth on the upper inner edge of the carpus , 

 and tufts of long setae on both joints. From the hind margin 

 of the propodite a raised keel topped with strong teeth runs 

 forwards and slightly outwards on to the fixed finger, extend- 

 ing far beyond the base of the dactyl. It is most prominent 

 near its proximal end and diminishes in height distally. The 

 hand is very broad in its basal portion, and narrows rapidly 

 to the tips of the fingers. The outer edge, which is fairly 

 sharp, especially at the proximal end, has a series of small 

 teeth. There is a line of blunt tubercles on the inner edge 

 as far as the base of the dactyl. The dactyl is smooth. The 

 lower surface of the hand is flat, and both fingers are slightly 

 but distinctly turned downwards near the tip. The keel of 

 the propodite falls away much more steeply on the inner than 

 on the outer side. 



The first two pairs of walking legs (second and third perei- 

 opods) are longer than the right cheliped, and those on the right 

 are slightly longer than those on the left. All the joints are 

 laterally compressed. The merus has a row of eight to ten 

 tubercles on the lower edge, and a line of setiferous scales 

 above. The carpus is much shorter, is thickened distally, 

 and bears a row of strong teeth interspersed with setae on 

 its upper surface. The propodite is longer than the carpus, 

 but shorter than the merus. It has a slight groove on both 

 the outer and inner face. On the upper edge there is a row 

 of setiferous scales, and on the lower a few, usually three or 

 four, transparent corneous spines, some of which are double ; 

 one is at the extreme distal end. The dactyl is strong, curved, 

 compressed, very slightly twisted, and grooved on the inside. 

 It ends in a strong t^ransparent claw. On the lower surface 

 there is a row of long, sharp, slender spines, about twelve 

 to fifteen, sloping forwards and diminishing in size backwards. 

 There are also a few similar spines a short distance above them 

 on the inner face, and a more numerous series near and on 

 the upper edge, especially in the distal half of the joint. The 

 upper edge is covered with tufts of setae. 



The fourth pereiopods are similar to those of E. Bernhardus, 

 but the chela is even more imperfect, the fixed finger of the 

 propodite being very short. 



In the fifth pereiopods the chelae are small and imperfect. 

 The area covered by the imbricate scales is slightly larger than 

 in E. Bernhardus. 



There are three fairly large unpaired pleopods on the left 

 side of the abdomen in the male. One ramus is much smaller 

 than the other, as usual. 



The uropods are of the usual type, the left being much 

 larger than the right.
