north and Paterson's Inlet (Stewart Island) in the south. 

 For the benefit of future collectors I may mention the follow- 

 ing localities as good collecting - grounds : Half-moon Bay 

 (Stewart Island). South Island— The Bluff, the Nuggets, 

 Akatore (near Tokomairiro) , very good ; Brighton , Lower 

 Green Island Beach, St. Clair, good ; Moeraki, Akaroa, fair ; 

 Taylor's Mistake, fair; Double Corner (Amberley), Kaikoura, 

 very good. North Island — Wellington Heads (Lyall's Bay, 

 Island Bay, &c., probably the best collecting-ground in the 

 colony for all forms of shore-life), Castlepoint, Kangitoto 

 Channel, Bay of Islands, very good ; Mongonui, fair. There 

 are, no doubt, many other good localities, particularly in the 

 North Island ; but a collector visiting any of the above is sure 

 to be well rewarded for his pains. 



I have to thank Mr. Crosby Smith, who has collected very 

 carefully in the neighbourhood of Dunedm, for a number of 

 localities for various species, and also for other kind assistance 

 in the preparation of this paper.
