Hah. — Coast of St. Domingo (Chemnitz); China (Ilwm'plhreys); 

 Atlantic Ocean (?) (Lamarck) ; Long Bay, Tasmania (Rev. H. D. 

 Atkinson) ; between Ball's Head and Goat Island, Port Jackson, 

 N.S.W., 18 fathoms, found in company with Modiola glaherrima, 

 Dunker ; off Sydney Heads, 45 fathoms (J. Brazier ^ May, 1864, 

 June, 1874); one valve dredged off Troubridge by Mr. E. H. 

 Mathews ; several living specimens and detached valves dredged 

 at 14 to 17 fathoms in Yankalilla Bay, South Australia, by Dr. 

 Verco (Professor R, Tate). 



Previous writers have recorded this very handsome species as 

 coming from the West Indies and the Atlantic and China. The 

 late Rev. J. E. Tenison- Woods was the first to record it from 

 Tasmania. I have specimens dredged by the Rev. H. D. Atkinson 

 that measure 2 inches in length ; our Port Jackson examples from 

 Ball's Head are a little longer ; younger specimens have been 

 dredged in various parts of the harbour and off Sydney Heads, 45 

 fathoms ; the species is very rare. 



Deshayes was the first to misquote Chemnitz's work in 

 Lamarck ; he there states that Afytilus arborescens, Chem., is 

 figured in Yol. ii. of the Conchylien-Cabinet. Hanley does the 

 same in his Catalogue of Recent Bivalves, 1843 ; Jay also in his 

 Catalogue, 1850; Reeve the same in the Conch. Icon., 1857; 

 Tenison- Woods in his Census of the Tasmanian Marine Shells- 

 1877 ; Professor Tate in Proc. Royal Soc. South Australia, 1890, 

 91. Hanley in Woods' Index Test,, quotes the correct Volume xi. 

 of the Conch. Cab., and gives Chemnitz's locality, St. Domingo ; 

 the species might have its home in the West Indies as well as in 

 Australia. My friend Mr. E. A. Smith records Lirna jnulticostata, 

 Sowerby, in the Report of the Lamellibranchiata, Zoology of 

 H.M.S. Challenger, Yol. xiii. p. 288, as having been dredged off 

 Bermuda in 1075 fathoms. This is a species common to Port 

 Jackson and the east coast of Australia and off Tongataboo in 18 

 fathoms.
