372 ARKIV FÖR ZOOLOGI. BAND 1. 



Male. Aa 15 and 1(3 of the prehnseile antenmila not 

 spiniferous. The simply curved Re 3 of the right oth leg 

 longer than Re 2. Re 1 — 3 of the same limb with Se. — 

 Length 1,5 mm. 



Habit at: Arabian Sea 1332' N. 50°4' E. (three somewhat 

 damagecl specimens). 



Description of the female. Body. Length of the anterior 

 part 1 millim., of the posterior part 0,5 millim.; 3 1 /? times 

 longer than broad. Anterior part 6-jointed; proportional 

 length of the joints 10:2:1,8:1,9:1,8:3,3. Rostral fila- 

 ments narrow. Last segment symmetrical, ending in back- 

 wards directed spines. Abdomen 3-jointed, joints of abont 

 equal length. Fur ca 3 times longer than broad, somewhat 

 longer than the 2 last abdominal segments together. 



Antennce of the lst pair reach beyond the furca, their 

 proximal segments not spiniferons. 



Äntennee of the 2nd pair. Bl with 1 plnmose Si not 

 reaching to the distal margin of B2. — B2 with 2 Si, one 

 as long as the joint, the other half as long. — Re longer 

 than Ri. Proportional length of Re 1 + 2, Re 3 — 6, Re 7 as 

 10:5:12. Distal margin of Re 2 strongly projecting. Sp of 

 Re 7 nearer the proximal than the distal margin of the 

 joint. Proportional length of B, Ri 1 and Ri 2 as 10:10:6,5. 

 Ri 1 with 2 Si, inserted distally. Ri 2 i 1 /» times longer 

 than broad. Le with 4 shorter and 4 longer S. 



Mandible. Trapezoidal, IV2 times longer than broad. B2 

 with 3 short Si. Re 4-jointed somewhat longer than Ri, with 

 f) (?<)) settfe. Ri 2-jointed. Ri 1 with one coarse and three 

 finer Si. Ri 2 with 6 -f 1 S. — Maticatory apparatus with 

 <S teeth, the exteriör tooth strong, by a gap separate from 

 the others, of which 2 — 6 are double and 7 — 8 bind. Si small 

 scarcely longer than the innermost tooth. 



Maxilla as long as broad. — Li 1 with strong falciform 

 sparingly hairy spines, the distal as long as the lobe — Li 2 

 with 3 S. — Li 3 developed. B2 and Ri 1 and 2 nniting. 

 Ri somewhat longer than Re. 



Maxillipeä 1 stont, the lobes crowded towards the end, 

 carrying strong spiniferous S. The lst lobe with 4 S. 



Maxillipeä 2. Proportional length of Bl, B2 and Ri as 

 10:9:7. Bl with the lobes 2 — 4 strongly projecting. — L2 

 with one long spiniferous S and one small plumose S. — L3
