as long as broad, fingers as long as palm. According to Paulson the proportion between the 

 length of the two subequal legs of the 2'"^ pair should be like 226 : 205, in the present spe- 

 cimen it is like 226: 202. Also in the other specimens there are 13 segments in the carpus. 



This specimen bears still the right leg of the y^ pair, the left is lost like also the two 

 posterior pairs. This leg is 6,38 mm. long and very slender; ischium with 2 spines on the 

 lower margin, one at the base, the other a little beyond the middle; merus 1,76 mm. long, 

 with 5 spines on the lower margin, carpus 1,7 mm. long, almost as long as the preceding 

 joint, propodus 1,1 mm., two-thirds of the carpus, dactylus 0,38 mm. long, one-third of the 

 propodus. 



Eggs small, 0,22 mm. long. 



In Paulson's female the carapace was 4,5 mm. long, his specimen had the same size 

 as those described above.

Stat. 181. September 511. Ambon-anchorage. 54 m. Bottom mud, sand and coral, i female 

 of medium size. 



This female is 23 mm. long (carapace 7,8 mm., abdomen 15,2 mm.). The rostrum 

 extends a little beyond the eyes, though it is still distinctly shorter than basal antennular 

 article ; it is 2 mm. long, slightly more than one-third the rest of the carapace and the greatest 

 height at the pro.ximal third measures just '/^ the length ; of the two teeth in which the rostrum 

 terminates, the lower is one and a half as long as the upper. 



Antennular peduncle as in the female from Stat. 260 (1. c), but the 2°<^ joint is i^^-times 

 as long as 3''''. The external maxillipeds project by the two last joints beyond the antennal 

 scale. The merus of the right chelate leg reaches just beyond the ba.se of the terminal joint 

 of the antennal peduncle and, measured laterally, appears 6,4-times as long as thick in the 

 middle; the carpus, that measures -/s of the merus, appears 2,9-times as long as broad distally 

 in a lateral view, being a little more slender than in the full-grown female from Stat. 260. 

 While the merus is 3,7 mm. long, the carpus and chela show respectively a length of 1,5 mm. 

 and 2,1 mm., the chela being one-third longer than the carpus, in the full-grown female, 

 however, almost one and a half as long ; fingers nearly half as long as the palm. The simple 

 left leg is wanting. 



As regards the other peraeopods 1 confine myself to indicating the measurements only 

 of those of the 5''> pair: merus 4,9 mm. long, carpus 4,5 mm., propodus 4 mm., dactylus 1,4 mm.
