Stat. 306. Febr. 8, 1900. 8°27'S., I22°54'.5E. Lobetobi Strait. 247 m. Bottom sandy mud. 



91 specimens, viz. 35 males and 56 females, that are nearly all egg-laden. 

 Stat. 312. Febr. 14, 1900. 8° 19' S., ii7°4i'E. Saleh-bay, North coast of Sumbavva. 274 m. 



Bottom fine, sandy mud. 126 specimens, viz. 46 males, 50 females, 22 of which 



are ova-bearing and 30 young specimens. 



The rostrum which in the adult species is 2 — 2 1 / 3 -times as long as the carapace and 

 in younger individuals even 2 1 /.,-times, is very slightly depressed as far as the tip of the 

 antennular peduncle and from here it is moderately curved upwards, running then straight 

 forward to the acute tip ; the gastric carina begins on the middle of the carapace, it is low 

 and rounded. In Fig. Sa of Borradaile's paper the rostrum runs almost horizontally forward, 

 but Dr. Calman wrote me that in the three cotypes of the British Museum Collection the 

 rostrum is distinctly bent upwards near the base. The upper margin is finely and evenly serrate
