Til dealing; with such protcaii forms as th(; ineinbors of this •^cnus, 

 it seems preferaljU; to allow considei'aljh! hititu(]o f(jr variation 

 than to erect a new species upon scanty material.

 Botany Bay ; one specimen from each locality.

Gmelin's name was founded on a drawing by Lister of a sliell 

 from Barbadoes. It is improbable that Reeve correctly identified 

 this with an Australian species. Means are wanting to disen- 

 tangle the complicated history of the species, and it suffices to 

 say that the one figured by Reeve is that before me. 



From 4-1-50 fathoms off" Cape Three Points. 



CASSIDEA PYRUM, Lamarck, var. THOMSONI, Brazier.

Brazier's type of this species is in the Australian Museum. It 

 differs from C. pyriini var. paucirugis, Menke, by the multiplica- 

 tion of the grains on the shoulder. 



From 41-50 fathoms off Cape Three Points ; one specimen.
