Fig. 107. Epimeria excisipes, n.sp. Side-plates 

 4-7 and 2nd joints of peraeopods 3-5. 



Description. Integument, rostrum, peraeon and pleon as in inermis Wlkr., but side- 

 plates 4-6 thicker and more strongly gibbose. Side-plate 4 concave on lower hind 

 margin, lower margin straight or slightly concave, antero- and postero-inferior angles 

 quadrate, almost sharp in some specimens. Side-plate 6 pointed below (rounded in 

 inermis). The lower margins of the peraeon segments are not at all tuberculate or gibbose. 

 Some specimens are almost foveolate on the pleura of pleon segments 1-3. 



Peraeopods 3-5, 2nd joints closely resembling those of robusta Brnrd., but that of 

 peraeopod 5 distinctively expanded in its proximal two-thirds into a broad lamina, 

 bounded below by an acute re-entrant angle. In some of the smaller S3 this re-entrant 

 angle or excision on all three peraeopods is more a right angle than an acute angle.
