Plate III. 



Tri/pJiositen chevreuxi Stebbing. 



n.s. Line indicating natural size of male specimen figured below. 



a.s., a.i. First antenna and part of the second. 



(fti. 1, (/n.2. First guatliopod with distal portion more highly magnified, and second 



gnathopod. 

 p7-p. 2, 3, 5. Second and third perajopods, the latter without the branchial vesicle ; 



fifth perieopod, with second joint only partially figured for economy of 



space. 

 urp. 2, urp. 3, T. Second and third uropods ; telson in dorsal view, with higher 



magnification of the apex of the lelt division. 



The separate parts are enlarged to a unifoi'ui scale, with additional enlargements 

 of the first gnathopod and the telson. 



Plate IV. 



Faripliimedia normani (Cunningham). 



M.S. Line indicating natural size of female specimen figured below. 



C. Partial side view of head. 



I.S., l.s' . Upper and lower lips. 



m., m.v. 1, m.v. 2. Mandible, first find second inaxilhe. 



ffti. 1, ffn:2. First and second gnathopods. 



All tlie separate parts, except the head, are magnified to a uniform scale. The 

 marsupial plate of the second gnathopod is omitted. 



Plate V. 



Fariphimcdia normani (Cunningham). 



mxp. Maxillipeds. 



prp.2,'i,o. Second and tliird pera'opods incomplete, and fifth pera?opod. 



urp. 1. First uropod, the peduncle incomplete. 



urp. 2, tirp. 3, T. Dorsal view of second and third uropods, with the telson. 



For economy of space the pera>o])ods are given on a lower scale of magnification. 

 The other parts are uniform with those of the preceding Plate. 



Plate VI. 

 3Ionocidopsis vallentini Stebhing. 



n.s. Line indicating natural size of the specimen figured below. The figure is parth, 

 schematic, as prior to dissection details of the crowded overlapping limbs 

 could neither be clearly seen nor satisfactorily represented. 



a.3., a.i. First and second antenmc. 



I.S., mx. 1, vi.v. 2. Upper lip, first and second maxilla?. 



g)i.\,gti.2. First and second gnathopods. 



Plate VII. 



IlonocnJopsis vallentini Stebbing. 



)».. l.i. Mandible and lower lip. 



prp. 2, 3,4,5. Second, third, fourth, and fifth pertpopods. The branchial vesicle and 



marsupial plate of the second perseopod are omitted. 

 pip. A pleopod. 

 urp. 1, 2, 3, 3. The right first uropod, the left second uropod, the pair of third uropods, 



with the peduncle only of the left first and the right second. The telson 



appears as if it were attached to the fifth segment ot the pleou, but is really 



attached high up on the sixth which it overlaps. 



In this and the preceding Plate the mouth-organs are more highly mngnified than 

 the other parts, but each set is on a unilorm scale.
