prior use of Roxana for a genus of insects, and he proposes Damoniella in 

 place of it, with Bulla crancki Leach as genotype. So far as I can judge 

 from the description and figures (7), this is a near aily of the new species ; 

 there is an Australian species, Atys dactylus Hedley (8), which also appears 

 to resemble it, at least superficially.

Callochiton empleurus (Hutton).* 



Foveaux Strait, N.Z. ; about 15 fathoms. 



A specimen of this rare chiton was recently found amongst a quantity 

 of oyster-scrapings obtained from the New Zealand Trawling and Fish- 

 supply Company, Wellington. The material came from the Foveaux Strait 

 oyster-beds, and amongst it quite a considerable variety of Mollusca was 

 found. 



The specimen now exhibited is unfortunately badly broken, but as the 

 anterior and posterior valves are practically perfect it is possible to supple- 

 ment Suter'sf description in some details which for lack of material he was 

 unable to determine. 



The anterior valve has 14 very shallow, irregularly-spaced slits ; the 

 teeth are comparatively solid, with their edges lightly grooved. The interior 

 is white, and has an irregular squarish pattern, due to the intersection of 

 the three concentric growth-lines, and of the slit-rays, which are traceable 

 to the apex. 



The posterior valve has 11 slits; the teeth are solid, are slightly thinner 

 than the anterior ones, but are similarly grooved. The interior is white, 

 with a bright pink patch under the mucro.
