(Plate vii., fig.3.) 



The cotype of T. strigata here figured is 18 mm. in length, 

 painted with longitudinal stripes of white and red or green. The 

 type-locality is Swan Point, near King's Sound, N.W. Australia. 



Mr. Smith writes of T. mundula — " This is certainly only a 

 young specimen of T. strigata A. Ad. We have the type of 

 mundula presented by Angas, and I have very carefully com- 

 pared it with strigata." The habitat of T. mundula is Shark's 

 Bay, W. Australia. 



I consider that T. baudini Fischer, was founded on a young 

 Thalotia strigata. Prof. Tate assigned this name to a Tasmanian 

 shell, but in this I cannot follow him; nor do I know any other 

 Tasmanian shell which suits the figure of Fischer. The type of 

 T. baudini was said to have been collected on King Island, Bass 

 Strait; but there are other cases where shells from N.W. Aus- 

 tralia are credited to Tasmania by the naturalists of the same 

 expedition. 



Cantharidus punctulosus A. Adams. 



A. Adams, Proc. Zool. Soc. 1851 (1853), p. 169. 



This species was reported to have been obtained by Jukes in 

 4 faths. Swan River, W. Australia; and has not been again 

 noticed in literature. A cotype lent by the British Museum 

 shows the species to be synonymous with Trochus nitens Kiener. 



Cantharidus moniliger A. Adams.

 Pveported to have been obtained by Jukes in 8 faths. Swan 

 River, W. Australia. I consider the cotype lent me to belong
