nearly touching the hind margin above. First 4 pedigerous segments com- 

 bined subequal in length to the carapace. Pleon with telson longer than 

 preceding portion of the body. Telson as long as 5*^ and about twice as 

 long as 6^^" pleon segment, with 2 or 3 pairs of lateral spines, and 5 apical 

 of similar size, only the median spine a little the largest. Antenna 1, 1^* 

 joint of principal flagellum only a little shorter than the accessory, Peraeopod 1 

 not very elongate, 5*^^ 6**^, and 7*^ joints subequal in length. Peraeopod 2, 

 6*^ and" 7^'^ joints subequal, 5*^ joint subequal to both combined. Peraeo- 

 pods 3, 4, with 3 or 4 plumose setae on apex of the rudimentary exopod 

 in o, and others on the P* joint of it, the exopods in the d fully deve- 

 loped. The 6 without pleopods, in accord with the generic character. Peduncle 

 of uropods as long as the telson and also subequal to the endopod. the 

 exopod a little shorter, its 2 joints subequal; medial margin carrying 10 spines 

 on peduncle, 16, 5, 2 on the 3 joints respectively of the endopod. L. o 

 9 mm, 6 not fully mature 8-5 mm.

Pseudorostral lobes very short, obtuse. Carapace dorso-ventrally somewhat 

 depressed; a depression between the eyelobe and the frontal lobe. Pedigerous 

 segments combined shorter than the carapace. Pleon decidedly longer than 

 preceding part of the body. Telson about three-fourths as long as peduncle 

 of uropods, with 5 pairs of small spines on the distal third, and 5 very 

 strong apical spines. Eye entirely wanting. Antenna 1 almost three-fourths as 

 long as the carapace, P* joint of principal flagellum only a little shorter than the 

 accessory. Peraeopod 1 elongate, 6*'' joint rather longer than 5*^\ Peraeo- 

 pod 2, 7*^ joint twice as long as Q)^^ and half as long as 5*^^. The 2-jointed 

 exopod of 'M peraeopod more strongly developed than is usual in the 9 of 

 this family. Peduncle of uropods nearly as long as 5*^^ pleon segment; 

 endopod with close row of unequal spines on the medial margin. Colour 

 white. L. about 7 mm. 6 unknown.

Like Hemilamprops imiplicata (p. 58) in having a single pair of lateral 

 ridges on the carapace, but with well marked sinus to the pseudorostral 

 lobes defined by acutely produced antero-lateral angle; telson, as long as 

 peduncle of uropods with 5 or 6 spines on each side not symmetrically 

 arranged, and 3 apical spines, the median the longest: P*- peraeopod not 

 very elongate, with 5*^, (i^^, and 7tii joints subequal: exopod of uropods 

 only slightly shorter than endopod. with its P^ joint scarcely half as long- 

 as the 2"*^. L., ovigerous , 12-7 mm. d unknown.

Carapace narrow, eyelobe without visual elements, pleon slender, telson 

 carrying 3 apical spines. First antenna with both flagella elongate. Second 

 antenna of female four-jointed. Palp of first maxilla with a single filament.
