The discovery that this little-known species of Reeve is a 

 Lupidojyleurus, extends considerably tlie range of the group. The 

 genus is generally regarded as belonging to the North Atlantic and 

 Korth Pacific oceans, and its discovery in the Southern Ocean is of 

 much interest, the nearest known species formerly having come from 

 deep water off the Philippine Islands. I had proposed to describe 

 this shell as a new species ; and so also, I find, had Mr. Pilsbry, 

 from specimens he had received from New Zealand. On comparing 

 Reeve's Chiton inquinatus with another species, I was struck by the 

 remarkable resemblance between the two forms ; and, having had the 

 advantage of separating the valves of one of Reeve's specimens, I am 

 enabled to be positive as to the identification. Reeve's type came 

 from Tasmania, and the species is therefore common to New Zealand, 

 Tasmania, and Victoria. The sculpture of the valves is not well 

 shown in the original figures ; the general outline and colouring 

 are fairly accurate ; some specimens, however, are much darker.

p. 50, pi. X, fig. 7 ; vol. XV, p. 67. 

 Zcptochiton versicolor, A. Adams : Proc. Zool. Soc. 1852, p. 92, pi. xvi, 



fig. 5, May, 1854; Angas, Proc Zool. Soc. 1867, p. 223. 

 Lepidopleurus empleurus, Hutton : Trans. N.Z. Inst., vol. iv, p. 178; i 



Man. N.Z. Moll., p. 113, 1880; Pilsbry, Man. Conch., 



ser. I, vol. XV, p. 67. 



Three small specimens appear to be the young of this species. 

 Mr. Pilsbry, in his last volume dealing with this group, has raised 

 C. crocinus to the rank of a species, after having in the earlier volume 

 placed it as a synonym. From an examination of the specimens in | 

 the Rritish Museum, I cannot see sufficient specific distinction.
