Ni/ctijiJianeft Couchii is very like N. anstralisj (Jr. (). Sars 

 ('Challenger' Re[)ort, p. 115, pis. xx. and xxi. figs. 1-7), 

 except that in the former there is a spine at the base of the 

 telson and a small preanal spine, which are absent in the 

 latter. The male also of N. Couchii agrees most closely with 

 N. austraiis in the form of the hinder margin of the carapace 

 and the sexual developments of the ])leopods [vide ' Chal- 

 lenger ' Report, pi. xxi. figs. 8, 4, 6, 7). As regards the 

 first pleopod, the likeness is not merely one of general 

 character, but the serrated edge of the one margin and the 

 single seta of the lateral lobe of the other margin are identical. 

 But with respect to the male antennules, no leaflet corre- 

 sponding to that of the second joint in iV. Couchii is described 

 or figured in iV. australis.
