tachment surfaces for maxilla and maxilliped, pads of male slightly 

 longer than those of female. 



Female and male maxilla (fig. 216) 2-segmented, fu-st segment 

 slightly longer and more strongly developed than second. Second 

 segment narrow proximally, broader distally, bearing 2 saber-shaped 

 terminal processes with tuft of plumosities between them. Terminal 

 processes covered, for the most part, by scalelike projections, each 

 bearing minute, spiniform projections. Inner terminal process longer 

 than outer, with fuzzy proximal outer margin in addition to scale- 

 like projections. 



Female maxilliped (fig. 22a) 2-segmented, situated just posterior 

 and lateral to posterior end of postoral adhesion process, first segment 

 with narrow proximal region and greatly enlarged, ovoid distal region. 

 Second segment much smaller than first, articulating on pair of 

 small indentations of posterodistal surface of first segment, with 

 slightly curved, spinelike terminal process. Male maxilliped (fig. 

 226) similar, in outline, to that of female although with 2 adhesion 

 pads on enlarged portion of fu'st segment, terminal process of second 

 segment longer than that of female, more distinct from segment. 



Female and male thoracic legs I-IV biramous, protopodite ] -seg- 

 ment, rami 1-3 segmented. For nature of armature and legs, see 

 tables 8-9, figures 22c-^, 23a-6.

 Steenstrup and Lutken, 1861 



* Wilson (1907b) and Shiino (1954c) do not indicate this armature element. 



Remarks. — Yamaguti (1936) and Shiino (1954c) both point out 

 that Japanese specimens differ from the description given by Wilson 

 (1907b) in the shape of the third pedigerous segment, the arrangement 

 of the adhesion pads, and the number of spines on the thoracic legs. 

 I am indebted to Dr. S. M. Shiino for the loan of a female specimen
