measuring one-fifth the length of propodus, 272-times as long as broad,

 2 females without eggs. 



Stat. 282. 8°25'.2S., 127°18'.4E. Anchorage between Nusa Besi and 

 the N. E. -point of Timor. 27 — 54 m. Bottom sand, coral and Lithotham- 

 nion. 1 young specimen. 



Closely related to Nikoides Danae Paulson from the Red Sea, but 

 probably different, when the figures of the rostrum and of the left simple 

 peraeopod of the 1 st pair in Nobili's paper (Annal, des Sc. Nat. 9 e Série, 

 Zool. T. IV, 1906, p. 79, PI. 5, fig. 1 and If) are indeed accurate. 



Rostrum slender, as long as or but little shorter than the eyes, mea- 

 suring one-third the length of the rest of the carapace; the rostrum is 

 laterally compressed, the lower border appears in a lateral view slightly 

 convex proximally, slightly concave in its anterior half and the height 

 proximally is not yet one-sixth the length; the rostrum ends in two 

 very small teeth, that are comparatively much smaller than in Nik. 

 Danae, according to Paulson's and Nobili's figures. The carapace, rostrum 

 included, appears nearly twice as long as high and nearly half as long 

 as the abdomen. Abdomen, without the telson, 4-times as long as the 

 3 rd somite is high, resembling that of Processa canaliculata Leach, except 

 the telson, that tapers more considerably, the width of the tip being 

 only one-third the width proximally. 



Second joint of antennular peduncle 3-times as long as thick and one 

 and a half as long as 3 ld ; stylocerite very short, truncate. 



The two last joints of the external maxillipeds are of subequal length 

 and measure together two-thirds of the antepenultimate ; the ultimate and 

 four-fifths of the penultimate joint project beyond the antennal scale. 



Chelate leg of 1 st pair like in Nik. Danae Paulson. Merus of the simple 

 leg of 1 st pair more than 8-times as long as broad in the middle, carpus
