much smaller than the sixth, and, owing to the shortness of the seventh 



.segment, ends behind about on a line with it, both epiniera surpassing 



the first segment of the pleon. 



"Legs of the first pair slender, armed with a long slender dactylus, 



much curved near its base; propodus expanded with a large palmar 



lobe armed with a marginal row of 

 eight curved spines; carpus short, 

 with a single curved palmar spine. 

 Legs of the second and third pair 

 much like the first, but with only 

 six spines on the propodus. Legs 

 of the fourth and posterior pairs 

 slender, armed with spines princi- 

 pally at the distal ends of the 

 ischium, merus, and carpus. 



" First segment of the pleon very 

 short and nearly concealed by the 

 thoracic segments, narrower than 

 the next three segments, which are 

 about equal, acutely produced at 

 the sides so as to resemble in shape 

 the seventh epimeron ; fifth segment 

 narrower than fourth, but some- 

 what longer on the median line; 

 telson semi-oval, regularly rounded 

 behind and ciliated. Uropods equal- 

 ing the telson; inner angle of basal 

 segment produced, about one-third 

 the length of the inner ramus, which 

 is Ungulate, rounded behind, 

 slightly shorter than the outer, and 



less than half as broad; outer ramus subovate, spinulose along the 



outer border; both ranii ciliated except near the base. 

 Length, 13.5 mm.; breadth, 6 mm. 

 A single specimen of this species, the only one as yet known, was 



taken at Station 305, latitude 32 18' 20" north, longitude 73 43' west, 



from a depth of 252 fathoms." HARGER/'
