 Hah. — Central Pacific and Pauiuotus Islands (W. //. Pease) ; 

 Vavau, Friendly Islands, found in shaded places in the crevices 

 of coral above high water, specimens large, July 14, 1865 ; Great 

 Sirius Cove or Mossman's Bay, Port Jackson, found in clusters of 

 rock-oysters, Ostrea cucullata, Born, December 24, 1865 ; No. VI. 

 or Eclipse Island, Claremont Group, 9 miles east of Cape Sidmouth, 

 North Queensland, December, 1871 (Brazier). 



Specimens of this species from the above localities were sub- 

 mitted to Mr. W. H. Pease in October, 1871, and duly named 

 Laimodonta conica, Fs. ; and since that date others were sent to 

 the British Museum in 1879 and named from actual specimens, 

 and not from figures or descriptions. Since December, 1865, I 

 have never found the species in any part of Port Jackson. At 

 one time Stromhus luhuanus, Linne, was found on a sandy mud- 

 flat in vast numbers at low water at the Bottle and Glass rocks, 

 Vaucluse Bay, Port Jackson ; the species appears to have dis- 

 appeared from the Port since May, 1865; dead specimens have 

 been found on the north coast near the Richmond River.
