combined ; it is not silicate dorsally and is only very slightly 

 narrowed to a broad rounded apex. It is provided with five 

 pairs of dorso-lateral spiniiles and six terminal spines, of 

 which the innermost pair is the longest. 



The eyes are large and globose ; the cornea is deeply pig- 

 mented and is much wider than the stalk. No ocellus is dis- 

 tinguishable The antehnular peduncle (fig. 13) is almost 

 exactly the same as in the type species of the genus ; the basal 

 joint is much longer than the two following combined and 

 bears at its base an acutely pointed lateral process reaching to 

 almost half its length. In both sexes the outer flagellum is 

 strongly setose and is stouter and rather longer than the inner. 

 The peduncle of the antenna is not provided with a spine at its 

 low^er distal angle. The antennal scale (fig. T2) reaches fully 

 to the apex of the antennular peduncle ; it is scarcely at all 

 narrowed distally and is rather less than three and a half times 

 as long as wide. Externally it is almost straight and is pro- 

 vided with a series of stout forw^ardly directed spines, about 

 seventeen in number, on its distal three-fifths. The most an- 

 terior of these spines is not longer than any others of the series 

 and falls short of the produced lamellar portion of the scale. 

 The basal joint of the flagellum reaches to more than half the 

 length of the scale, the whole ramus being about half the en- 

 tii'e length of the animal. 



The mandihles (fig. 4) possess a small one-jointed palp, 

 which in the specimen dissected showed no trace of setae. 

 The incisor process is tipped with five teeth, while the molar 

 bears a number of bristles and a few^ minute teeth at its apex. 

 The first waxilla (fig. 5) has much the same outline as in L. 

 Paulsoni ; the outer lobe is fringed with setae on its external 

 margin ; the inner bears only two. The rounded basal lobe 

 of the second waxilla (fig. 6) is obscurely notched distally ; the 

 two anterior lobes project much beyond it, the outer being 

 wider than the inner. The endopod bears a single terminal 

 seta ; the exopod is long, setose and rounded at either end and 

 is more concave internally and distally than in Steb- 

 bing's figure of L. Paulsoni. The first maxilUpede (fig. 7) is 

 very like that of the type species, but the lamellar j^ortion of 

 the exopod slopes away rather more sharply from its connec- 

 tion with the distal lash ; the endopod is very narrow apically 

 and the epipod is large and bilobed. The terminal joint of the 

 second maxilUpede (fig. 8) is very much shorter and broader 

 than in L. Paulsoni. An irregularly shaped epipod is present 

 at the base ; distally this shows traces of breaking up into 

 lamellae and possibly becomes a functional podobranch in 

 some cases. The third maxillipedes are much swollen basally 

 and reach almost to the apex of the antennal scale ; they do 

 not possess an exopod and the ultimate joint is rather more 

 than one and a half times the length of the penultimate. 



The first pair of pereiopods is not longer than the third 

 maxillipedes. The ischium is more than half the length of 

 the merus ; the carpus is rather longer than the merus and is 

 more than twice the length of the small and slender chela.
