SPECIES DOUBTFUL FOR NEW ZEALAND. 



1. Chiton jugosus, Gould. 



Chiton conccntriciis, Heeve : Hutton, Trans. New Zealand Inst., vol. iv 

 (1872), p. 176; Man. New Zealand Moll., p. 111. 



Some specimens in the Colonial Museum are correctly referred to 

 this species, but their locality is not stated. I agree with Pilsbry tliat 

 the species is probably incorrectly reported from New Zealand. It is 

 not in the New Zealand collections in any of the other Museums, and 

 I am not aware that it has ever been found in our waters by recent 

 collectors. 



2. LoRicA voLvox (Reeve). 



Chiton [Lepidopleurus) rudis, Hutton : Trans. New Zealand Inst., 



vol. iv (1872), p. 179 ; Man. New Zealand .Moll , p. 113. 

 Chiton rudis, Hutton : Pilsbry, Man. Conch., ser. I, vol. xiv, p. 238. 



I have examined Hutton's tyj)C-specimen of Chiton rudis in the 

 Colonial Museum, and found it, as suggested by Mr. Pilsbry, to be 

 Lorica volvox. For the same reasons as those given in the case of the 

 foregoing species, I think it advisable to place it amongst the species 

 doubtful for New Zealand. 



3. ISCHNOCUITON CONTRACTUS (RcCVe). 



Lepidoplexirus contractus, Reeve : Hutton, Man. New Zealand Moll., 

 p. 113. 



The New Zealand habitat rests solely on Cuming's authority, and 

 that is not always reliable. It is not in any of our Museums as 

 coming from New Zealand, and I have no knowledge that it has ever 

 been found here.
