the constriction with three spines ; same behind the constriction with 

 numerous spines which regularly grow larger posteriorly ; the last pair 

 of spines remarkably strong, between which grow 2 hairs and 3 small 

 spines smaller than lateral ones. Outer branch of uropod much longer 

 than the inner and articulated at two-thirds of its length from base, 

 the distal joint shorter than twice its breadth ; the outer distal 

 margin of proximal joint provided with 9-12 spines, beginning a short 

 distance behind the middle of that margin. Inner branch of uropod 

 densely beset with spines, of which there are about 10 long ones, 

 separated from one another by about 3 much shorter ones. Average 

 length of body 9.2 mm. 



Locality. Near the Misaki Marine Laboratory. Also dis- 



covered in the stomach of Chipea sp. caught off the coast of Odawara 

 in Sagami Bay. 



Notes. — This species closely resembles Siriella vulgaris Hansen obtained by the Siboga 

 in the Indian Sea, but differs from it in the peculiar form of the inner flagellum of 

 antennule and in the greater difference in length of the two branches of uropods.

 Plate VIII., fig. 19. 



Diagnosis. Carapace with sharply pointed rostrum. Eye 



globose. Antennular peduncle with the third segment longer than the 

 first. Antennal scale reaching to middle of the last segment of 

 antennular peduncle, about four times as long as broad. Legs con- 

 spicuously slender, especially the fifth, the sixth and the seventh ; 

 propodite of the posterior three pairs of legs segmented into two joints 

 in the middle of its length, that of more anterior legs somewhat nearer 

 to base ; dactylopoditc strongly curved (fig. 19). Last leg shorter and 

 more feebly developed than other preceding legs. Telson linguiform, 

 its lateral margin armed with about 34 short and uniform spines. 

 Outer branch of uropod segmented at a point more proximal than
