REPORT ON THE CUMACEA. 73 



The uropoda (see fig. 21) are comparatively much shorter than in the preceding 

 species, scarcely attaining half the length of the tail. The scape is slightly serrate on 

 both edges, and exhibits a very marked squamous sculpture, the squamulse being rather 

 large and triangularly pointed. The branches exhibit the structure characteristic of the 

 genus. The inner branch is only slightly shorter than the scape, uniarticulate, with 

 the inner edge serrate, and moreover armed with two slender spines ; from the tip of 

 this branch three unequal spines arise, the middle one being by far the strongest. The 

 outer branch is a little smaller than the inner, and composed of two well-defined joints, 

 the first of which is quite short, whereas the last is rather elongate and gradually tapers 

 to the apex, bearing a rather long terminal spine, and a much smaller one on the inner 

 edge close to the apex. 



Habitat. — The specimens of this species were detected by the author in examining 

 a parcel of dredged mud preserved in strong spirits, and kindly sent by Mr. John 

 Murray. The mud was obtained on January 29, 1874, off Cumberland Bay, Kerguelen 

 Island, from a depth of 127 fathoms (Station 129h).
