This very rare species was first obtained by Mr. Richard Brinsley 

 Hinds during the voyage of H.M.S. ' Sulphur,' and by Mr. 

 Arthur Adams at Japan, and recently as far south as Tasmania 

 by the Rev. H. D. Atkinson. My first specimen I obtained at 

 the " Sow and Pigs' Reef," in 1865, rather sea-worn and over- 

 looked by me until now, the second specimen recently obtained 

 is in good condition and measures five lines long, it is lighter in 

 colour than type specimens.
