20: 



flagellum reaches barely to the apex of the antennal scale ; it is 

 fused with its fellow for some 7 or 8 segments, the fused portion 

 being about two fifths the length of the entire shorter ramus and a 

 little less than the length of the ultimate peduncular segment. 

 The basal portion of the inner flagellum is swollen. The antennal 

 scale is rather strongly narrowed anteriorly ; its length is about 

 three and a third times its greatest breadth and the distal portion 

 of the lamella extends far beyond the spine that terminates the 

 outer margin. 



The oral appendages and maxillipedes do not differ markedly 

 from those of L. serratus. The mandibular palp is composed of 

 three segments, of which the third is scarcely longer than the 

 second. The anterior lobe of the epipod of the first maxillipede 

 is not pointed as in Sollaud's L. mani. The antepenultimate seg- 

 ment of the third maxillipede is considerably expanded distally, 

 the exopod reaching only a little beyond the middle of its length. 

 The ultimate segment is only about one eighth shorter than the 

 penultimate. 



The first peraeopods reach a little beyond the apex of the 

 antennal scale. The carpus is a trifle shorter than the merus and 

 is about one and a half times the length of the chela. The fingers 

 are fully one and a half times the length of the palm. 



The second peraeopods in most cases reach beyond the anten- 

 nal scale by at least the length of the chela, sometimes by that of 

 the chela, carpus and a small portion of the merus. Measurements 

 (in mm.) of the separate segments in seven specimens are as 

 follows: —
