Wlien eollectiug in Auckland Harbour, I found a number of examples 

 of this little Chiton on the under-side of stones on a mudflat at low- 

 water. Specimens were also in the Museum, labelled Chiton sulcatus, 

 Quoy & Gaim. On examination I found it to be a Lepidopleunts, and 

 thinking it to be a new species, I sent in May, 1895, a number of 

 specimens in alcohol to Mr. H. A. Pilsbry, for further investigation. 

 In January, 1896, Pilsbry published a note (Xautilus, vol. ix, p. 108) 

 on this species, saying that it had been identified by Mr. E. 11. Sykes as 

 Eeeve's Chiton inquinatus on comparing it with the type in the British 

 Museum. Mr. E. R. Sykes also published a note on the species in 

 our "Proceedings" (antea, p. 86). 



ITab. — Auckland Harbour (H. 8.); Brighton, Otago (A. Hamilton). 



The species has also been found in Tasmnuia (Reeve's type), South 

 Australia (Betlnall), and Port Phillip, Victoria (Wilson).
