Remarks. My figures of the anterior end, the telson and a uropod of an adult female of this species 

 are drawn to the same scale as the corresponding parts of adult specimens of Eucopia unguiculata and 



Fig. 5. Eucopia grimaldii Nouvel. A, anterior end of female in dorsal view, x 6; B, telson and right 



uropod of female in dorsal view, x 6. 



E. australis in order to show the salient differences between the three species. The thoracic endopods 

 resemble those of unguiculata, being long and comparatively slender, but in australis the carpo- 

 propodus of the fourth thoracic endopod is markedly stronger and more robust than that of the 

 second and third appendages. 



In many respects this species occupies an intermediate position between unguiculata and australis. 

 It is larger and more robust than the former, but does not attain to a size comparable with the latter. 

 The antennular peduncle resembles that of australis, the inner margin of the third segment being much 

 longer than the distal margin and produced distally into a pronounced setiferous lobe. It is less robust, 

 however, than in australis and the articulation of the second and third segments is not so oblique (cf. 

 Figs. 4C and 5 A). The antennal scale has much the same proportions as in unguiculata, but its outer 

 margin is markedly sinuous. I cannot find any definite sexual dimorphism, such as is found in the 

 scale of australis. The apex is asymmetrical. The most outstanding difference between this species and 

 the other two lies in the shape and armature of the telson. This is more rounded at the apex and the 

 lateral spines are very long. The small spines are not much shorter than the long ones and there are 

 only two or three in the distal space between the distal long lateral spine and the long apical spines 

 (cf. Figs. 4B, D and 5B). The spines at the distal end of the proximal segment of the exopod of the 

 uropod are very long.
