The trachypterid now under consideration is therefore the 

 ninth example ■ of which we have any definite record from the 

 Australasian Colonies, and as it differs somewhat from any of 

 the others I am constrained to submit the following detailed 

 description, and in the belief that it will prove to be worthy of at 

 all events subspecific rank, the name pohjstictns is here proposed 

 on account of the numerous spots which ornament the head and 

 body. 



t lu an editorial note to Clai-ke's paper Sir James Hector remarks : — 

 " Tlie author has overlooked the occurrence of another specimen of this 

 species '' (? species of this genus) " T. altivdh, Kner, in the Auckland 

 Museum; and other specimens, since collected, are in the Wellington and 

 Dunedin Museums." I can find no record of any such specimens, and am, 

 therefore, unable to include them in my list.
