38 G- O. Sars. 



The legs, on the whole, are constructed in a very similar 

 manner to that found in E. JPackardi, but their number is 

 greater, 23 pairs being distinctly counted in both sexes, and 

 perhaps a 24th rudimentary pair may yet be present behind 

 the others. On a closer examination, the epipodites are 

 found in some of the pairs to attain quite an unusual 

 development, as shown by figs. 5 and 6. They succes- 

 sively increase in length from the 1st to about the 7th 

 pair, where they reach their maximum length, nearly equal- 

 ling that of the endopodite (see also fig. 11). From the 

 1st pair they again successively diminish in size In JE. 

 PacJcardi these parts are much more uniform in size, 

 and in none of the legs exceed half the length of the 

 endopodite. 



The structure of the 2 anterior pairs of legs in the 

 male, (figs. 9, 10) agrees almost exactly with that in JE. 

 JPackardi. As in that species, the hand has the inner edge 

 quite smooth (see fig. 9 a), whereas in JE. cycladoides, according 

 to the statement of Dr. Simon, it forms behind the thumb 

 a well-marked angular projection. In the succeeding pairs 

 (see fig 11) a slender biarticulate appendage is appended 

 to the penultimate lobe of the endopodite, as in the male 

 of most other species. 



The tail, or caudal piece, exhibits in the female (fig. 5) 

 a similar structure to that in the Australian species. In 

 the male (fig. 6), on the other hand, the terminal, claw-like 

 processes of the caudal plates are much stronger, and very 

 asymmetrical, the right one being considerably more curved 

 than the left, and projected at rather a long distance above 

 it (see also fig. 8). 



The colour in living specimens is reddish brown, with 

 a dark shadow extending on each side from the umbones
