to the elimination of Area pistachia, Lamk., from Queensland 

 shells, and a further objection may be made to striking 

 Thalotia tricingulata, A. Ad., off our lists. This shell is 

 found plentifully at Murray Island, and extends at least 

 as far south as Gladstone. It agrees far too closely with 

 Monodonta diminuta* Hedley, which is likely to prove a 

 synonym. 



]VIr. Hedley's " Studies of Austrahan Mollusca," Part 

 XII., contains much important matter for the collector 

 and systematist. There is a rearrangement of the former 

 overweighted genus Voluta giving generic rank to a number 

 of its subdivisions, and rearranging under these all known 

 Australian species. The beautiful shell, Scaphella reticu- 

 lata, Rve., disappears from the Queensland list, Mr. Tom 

 Iredale proving that this name had already been used, 

 and renaming it S. hedleyi. A very appreciative article 

 on the French conchologist Montrouzier is introduced in 

 connection with a generic name given in his honour by 

 Souverbie which lapses, ha\^ng been previously appro- 

 priated in entomology. 



In the examination of protean forms of Acmcea and 

 Helcioniscus pertinacity and keen research are exhibited, 

 and many tangled skeins are straightened for the assistance 

 of the student. To those who have similar work to do 

 in other branches of biology, a study of the argument 

 upon the many-named Patella tramoserica, Chemnitz, 

 will be of service. 



All descriptions are detailed enough to aid recogni- 

 tion, without being so minute as to be true of the type 

 specimen only ; and the plates, as is always the case in 

 Mr. Hedley's papers, are models of their kind. A large 

 proportion of the new species are additions to the Queens- 

 land fauna. 



Mr. Tom Iredale, the authority on Chitons, paid a 

 visit to Queensland during the meeting of the Australasian 

 Association in Brisbane, 1909. He collected round 

 Caloundra, at the northern end of Moreton Bay, where he 

 obtained fifteen species, of which ten had not previously
