Myodora Tasmanica, n. sp., Ten. Woods, Proc. Roy. Soc, 

 Tasm., 1875 (1876), p. 160. Type locality — Long Bay, Tasmania.

 p. 422, pi. xxvii., figs. 104-106. 



Dredged off Beachport in 100 fathoms, 5 valves; in 110 

 fathoms, 50 ; in 150 fathoms, 2 ; and in 200 fathoms, 2 valves. 

 It was not taken in shallower waters off the same place, and 

 has not been taken on the South Australian beaches. It ap- 

 pears not to have been recorded from Victoria nor from New 

 South Wales. 



Crassatellites kingicola, Lamarck. 



This shell was referred to by me in these Transactions, vol. 

 xxix., 1905, p. 169, as ('. ponderosus, Gmelin. It appears now 

 that our G. castanea, Reeve, should be regarded as a variety 

 of C. kingicola, Lamarck. 



It has been dredged in a subfossil state in soft limestone 

 in the Port Adelaide Channel. One valve was taken in 40 

 fathoms, and two in 100 fathoms off Beachport, both small 

 and poor. Hitherto, therefore, its habitat has been very re- 

 stricted as to depth, viz., from 15 to 20 fathoms. 



Crassatellites discus, Hedley. 



Crassatellites discus, Hedley, Records Austr. Mus., vi., 1907, 

 p. 300, pi. Ivi., figs. 26-27. Type locality, 80 fathoms, off Xarra- 

 been. New South Wales. 



None were dredged alive, but valves in good condition 

 were obtained. Off Beachport, at 40 fathoms, 31 valves ; at 

 49 fathoms, 22 valves; at 100 fathoms, 4 valves; at 110 fa- 

 thoms, 20 valves; at 150 fathoms, 17 valves; and at 200 fa- 

 thoms, 2 valves. Off Cape Borda, at 55 fathoms, 7 valves ; and 

 at 62 fathoms, 5 valves. Off Cape Jaffa, in 130 fathoms, 14 

 valves. This seems not to occur in the gulfs of South Aus- 

 tralia, but to be an ocean form, and to affect the deeper 

 waters. 



Crassatellites carnea, Tate. 



Crassatella carnea, Tate, Trans. Roy. Soc, S. Austr., vol. 

 xiv., p. 263, pi. xi., f. 1, 1a. Type locality — Yankalilla Bay. 



It has been dredged alive at all depths from 9 to 23 

 fathoms, most abundantly from 20 to 23 fathoms. Valves 

 have been taken, small and in poor condition, off Beachport 

 at 110 and 200 fathoms, and off Cape Jaffa, in 90 fathoms. 

 Comparatively large valves were taken off Beachport in 40
