Ici'tion. Ill three speciuiens from New Zealaiul, the ro.struiii is onlv a 

 little l()ti(:;er than the eyes and the su]>ra()cular spines arc wry short 

 and much more diverj^-ent than in the adults. The eyestalks are pro- 

 portionately longer than in any species of the genus in the collection. 

 In alcohol the e^^es are transverse in direction and extend beyond the 

 line of the sides by about one-half of the diameter of the cornea. 

 The antero-lateral angles are 

 rounded in the young, in sharp 

 contrast with the angles of the 

 adult, which are armed with a 

 large double spine, g'iving it 

 an angular appearance. The 

 carapace in the young has the 

 two spines on the gastric area 

 behind the supra-ocular spines 

 and a very small paired spine in 

 line with these. The posterior 

 margin of the cervical suture is 

 armed with four spines. In 



addition to these spines in the adult there are about eight spines on 

 the tirst ciliated line behind the gastric pair and another pair posterior 

 to these. The armature of the abdomen is the same in both forms; 

 th(; maxillipeds are similar, but longer in the young. 



The three specimens from New Zealand range about 4:5 nun. in 

 length while numerous specimens of the adult from the Straits of 

 Magellan range from 110 to 115 mm. Younger specimens ma}' vary 

 nmch more from the adult form.
