Obs. — In view of the ordinary laws of priority it does not 

 seem possible to accept Adamsia for this shell as that name was 

 preoccupied by E. Forbes for an Actinian genus in May, 1840 

 in the Annals of Natural History, 2nd series, vol. v., p. 181. 

 On this account the late Rev. J. E. T. Woods proposed Agnewia 

 to take the place of Adamsia and it seems only just that this 

 should stand. Adamsia tritoniformis, Blainville, of New South 

 AVales is clearly the same as our Victorian shell commonly known 

 as Adamsia typica, Dunker, determined by a careful comparison 

 of actual specimens. Tryon apparently regards Adamsia adelaidte, 

 Adams and Angas, and Purpura neglecta, Angas, as trifling 

 varieties of Dunker's species. This, however, cannot be accepted. 

 His figure 488 on plate 39 may probably represent C. albolirata, 

 a variety of Sistrum adelaidensis, and from an examination of 

 specimens of Adamsia adelaida-, Ad. and Ang., forwarded from 

 Port River, South Australia by Dr. Verco, we have concluded 

 that the latter is but a slight varietal form of Sistrum ade- 

 laidensis. Tryon's figure 496 clearly represents Purpura neglectn, 

 Angas, or what is the same thing Sistrum reticulatum, Crosse, 

 but this cannot by any stretch of the imagination be regarded as 

 C. tritoniformis, Blainville.
