 I would include Allorchestes under Hyale, and 1 cannot follow Mr. A. 0. 

 Walker in his generic distinction.* 



In my paper on the synonymy of the New Zealand Orchesfidae (Trans. 

 N.Z. Inst., vol. 31, p. 197) I gave a brief diagnosis of the New Zealand 

 species as I limited and defined them. I hoped to work out these in detail 

 and illustrate my contention fully, but pressure of parliamentary sud other 

 work has quite prevented me from doing so. So two or three years ago 

 I handed over all my collections, dissections, notes, and drawings to my 

 friend Dr. Chilton, in the hope that he would be able to clear up the con- 

 fusion ; but he, too, has had abundance of other work, so the matter has 

 to remain unsolved for the present. Meanwhile the present identifications 

 refer only to the species as defined in the paper referred to, the classifica- 

 tion employed there having been adopted in the " Index Faunae Novae- 

 Zealandiae," p. 257. f

 Common in and around Otago Harbour. 



76. Orchestia chihensis Milne-Edwards.

 about the harboxir, where 1 have found great colonies under pieces of whale-

" On sandy beaches, usually just above high-water mark." This is a 

 burrowing species, and is not very common.

 old seaweed, below which it digs its shallow burrows." Very common.
