Mr. A. U. Henn collected on the Cottesloe Beach, about four 

 miles north of Fremantle, W.A., and sent to me a shell which I 

 have identified with this long lost species. Further, it seems to 

 me certain that Haliotis fauta, Reeve,* collected by Lieut. 

 Preston at the " Swan River Settlement," is the same as Menke's 

 species. I note that though Reeve's figure is the exact length 

 given by Menke for R. semiplicata, yet it is 4*5 mm. narrower 

 than the breadth of //. semiplicata. As the specimen from 

 Cottesloe is of broader proportions than Reeve's illustration, I 

 attach no importance to this discrepancy.

 dull white i bleached ?). Sculpture: about 20 low spiral ribs 

 arise by interstitial growth, broaden rapidly, denticulate the 

 margin and imprint the interior, the posterior rib dominating its 

 fellows: indistinct growth-strise cross the ribs and their narrow 

 interstices; the whole surface is granulate. The apex is inrolled, 

 of at least one whorl, vertical, with a median sinus. The per- 

 foration is a narrow slit, taking the place of two furrows and the 

 posterior rib on the crown of ther shell. The interior shelf 

 stretches far down. Aperture oval. Height 2 mm. Aperture 

 2*2 by 1'6 mm.
