AM PHI POD A. 281 



Lower antennae reaching the 4th body segment ; the 2nd joint rather shorter than 

 the 3rd ; flagellum subequal to these united. 



Mandibular palp with the 3rd joint shorter and wider than the 2nd, sub-oval, 

 widest near the distal end, which is truncate ; 1st joint very short (fig. 40. mp.). 



First maxillae : inner plate minute, with a single setule near the rounded top. 



Palps of the maxillipeds more slender than in L. webstt ri, the outer plates reaching 

 about the middle of the 2nd joint, armed with spine-teeth which increase in length 

 distally. 



First gnathopods : side-plates fully as deep as the segments, wider below, the 

 angles rounded ; 1st joint about twice as long as the next 3, rather shorter than the 

 hand ; 3rd joint rounded behind ; wrist small, triangular, almost coalescent with the 

 base of the hand; this has the front and hind margins subparallel and sparsely 

 setose ; the latter produced in a strong tooth beyond the base of the dactylus to the 

 point of which it is opposed, forming a chela ; a smaller tooth between this and the base 

 of the dactylus ; this has a prominent rounded tooth on the inner margin (fig. 40. gn. 1 ). 



Second gnathopods : side-plates irregularly rhomboidal, with rounded angles ; 1st 

 joints stronger than in the 1st pair, wider than any of the other joints, and about as 

 long as the hand; this is a little longer than, and subequal in width to, the wrist, 

 margins parallel, setose : palm small, oblique. Dactylus reaching much beyond the 

 palm (fig. 40. gn. 2 ). 



First and 2nd peraeopods : side-plates rounded below, deeper than the segments ; 

 1st joint relatively wide, 3rd nearly twice as long as the 4th, and wider at the distal 

 end; the whole very sparsely setose (fig. 40. pp. 1 ). 



Third peraeopods but little longer than the 2nd ; 1st joint widely oval and about 

 as long as the next 3 ; 3rd longer than 4th, the two together rather longer than the 

 5th, which is slender, and has 2 or 3 spines on the front margin. 



Fourth and 5th peraeopods are subequal, the latter shorter than is usual in this 

 genus, only reaching the 2nd urus segment ; they are but little longer than the 3rd 

 pair, which they resemble, except the 1st joint, which is relatively shorter and 

 narrower (fig. 40. pp. 5 ) ; the 3 pairs are almost entirely without setae. 



The 3rd uropods extend a little beyond the 2nd, and these beyond the 1st; the 

 outer ramus of the 3 pairs is shorter than the inner ; in the 3rd the inner ramus is as 

 long as the peduncle, with a spine near the middle and 3 unequal terminal spines; 

 the outer has 2 or 3 short and 2 or 3 long terminal spines (fig. 40. up. 3 ). 



Telson rounded at the end, with a spine and a seta at each side. 



Length 2'5 millims. 



The characteristic features of this species are the angular ocular lobes, resembling 

 Gammaropsis, the chelate hand of the 1st gnathopods, and the comparative short- 

 ness of the last peraeopods. It is, however, very possible that the specimen was 

 immature. 



Another species of Lembos from Cheval Paar has the 1st gnathopods very like
