Haplocheira barbimana, G. M. Thomson. 
Fairly abundant in W.Q., Oct. and Nov., 1902, especially at Hut Point; also a 
Flagon Point, 23 Jan., 1902, and W.Q., 30 Sept., 1903. 
The appendage of the upper antennae, which was broken in the ‘Challenger’ 
specimen, is three-jointed, the first wider than, but subequal in length to, the second ; 
the third minute, reaching almost to the end of the second joint of the flagellum. The 
first urus segment has two small postero-dorsal teeth ; these are sometimes difficult to 
see, and may have escaped Mr. Stebbing’s notice, as they are not mentioned in his 
description. No sexual differences were observed. The females taken (except two on 
1 Oct., 1902, which had young in their pouches) had generally parted with their ova.
