tilth subequal, in each the outer or opercular plate is large, 

 rounded, very delicate in structure and regularly fringed with 

 line seta?, the endopod is small and rounded. 



The uropods (fig. 20) have the basal joint about as broad as 

 long, inner ramus attached only slightly anteriorly to the outer, 

 both rami slender, cylindrical, tapering slightly and ending in 

 a small tuft of long seta?.

Text-fig. 20. Uropoda and terminal segment. 



The terminal segment (fig. 20) is only slightly narrower than 

 the preceding segment, and has the lateral portions better de- 

 veloped than in other Oniscidae in which the terminal seg- 

 ment is usually reduced to a small triangular plate. 



The above description has been taken mainly from the large 

 male specimen first received and dissected. None of the other 

 specimens bear eggs or can for other reasons be definitely re- 

 cognised as female, and in all of them the leg's have the same 

 general character as those already described, though in the 

 smaller specimens the special characters of the first and second 

 I tails of legs are not so well marked. Two or three of the eight 

 specimens are certainly males, as can be seen without dissection
