The specimens, collected by the "Siboga", agree very well with the original description 

 of this species, which was obtained by the "Valdivia" near the Seychelles and near the south- 

 west coast of Sumatra. The male from Stat. 1S5 is 54,5 mm. long from tip of rostrum to tip 

 of telson, the full-grown female from Stat. 243 66 mm. The slender, thin and tapering rostrum, 

 which in the adult species is 3-times as long as the carapace, runs horizontally forward about 

 to the middle of the antennal scale and is from here rather strongly turned upward: according 

 to the original description, however, it should only be "ein wenig nach aufwarts gebogen". 

 A strong acute tooth is situated on the upper side just above the orbital margin and this 

 tooth reaches to the middle of the corneae, when the eyestalks are directed straight forward: 

 a much smaller tooth is placed immediately behind it. This first or posterior tooth, though 

 being rather of a small size, appears nevertheless larger than the other teeth of the upper 

 margin and therefore no doubt both are described by Balss as "zwei grössere Zahne". According 

 to this author the other teeth are placed on the distal half of the upper margin, in the present 

 specimens, however, they appear already in the male at the level of the middle of the antennal 

 scale, a little in front of the antennular peduncle, in the full-grown female at the level of the 

 distal third, but the first three or four of the series are very small, so that they may easily 

 be overlooked. In the adult specimens the upper margin is armed, besides with the two larger 

 proximal, with 15 teeth (according to Balss 10); these teeth are very small, though increasing
