In general form this is much shorter than the last two species, 

 the dermis not hispid, the animal not so pellucid, but stained 

 with yellow and having two black dendritic spots at the 

 termination of the sixth segment of the pleon, from whence 

 the colour branches down into the telson. Rostrum not much 

 produced, shortly triangular, acute at the apex, shorter than 

 half the length of the basal joint of the antennules ; no notch 

 on the front margin of the cephalothorax over the eye. 

 Eyes shorter than in L. gracilis and not so very much con- 

 tracted at the base. Antennules with basal joint hollowed 

 above, subequal in length to the two following joints. 

 Antennal scale almost exactly as in L. gracilis ^ except that 

 the second joint is somewhat shorter, occupying scarcely one 

 fourth of the total length, with four or live set^ on each side 

 and two terminal. Telson shorter tlian the inner uropods, 

 linguiform, extremity remarkably broad and widely rounded, 

 and occupied by four long spines and two, three, or four 

 shorter spines in each interval between them ; margins of 

 telson furnished with very numerous densely-set spines, 

 usually of rather unequal length towards the extremity. 

 Inner uropods much shorter than the outer (as about 2 to 3) ; 

 otolith large; beyond the otolith the uropod is narrower and 

 bears no spine at the extremity, but the inner margin is edged 

 with very numerous spines throughout its length, the spines 

 opposite the otolith being much smaller, slender, and crowded. 

 Length 17 millim. 



Hob. This species has been known to me as a member of 

 the British fauna for the last twenty-six years, at which time 

 I took it abundantly between tide-marks at CuUercoats,
