as other Limnceadce with the exception that occasionally they sway- 

 ed the forepart of their bodies from one side to the other, appar- 

 ently in quest of a frond nearer to them than the one in a direct 

 line, they also continually opened and shut their mouths, and gen- 

 erally carried the hind part of their shell closer to the tail than the 

 forepart to the head, so that the shell appeared to have an oblique 

 direction'. 



Polymorphous Anodontae. — By R. Ellsworth Call. — 

 American Naturalist, July, 1880, p. 529. 



The author from an examination of a large number of speci- 

 mens of Anodonta grandis Say, A. plana Lea, A. decora Lea, A. 

 Hockingensis Moore, MSS., and A. Someysii Moore, MSS., has 

 decided that they are all forms o{ gra?idis Say. 



In arriving at this decision, Mr. Call has made a very careful 

 diagnosis of the exo-skeletons of all and the soft parts of some, 

 and the opinion of their identity is further strengthened by the 

 fact, that being arranged geographically from the East to the 

 Mississippi, the former gradually approach the shell described by 

 Say in 1829. The differences correspond in general with the 

 modification of the mantle, some of them being sexual, but the 

 major part may be explained on the basis of distribution and 

 chana;es of environment. 



Synonymy of and remarks upon Port Jackson, 

 New Caledonian, and other shells, with their distri- 

 bution. — By John Brazier, C.M.Z.S., &c. — From Proceedings 

 of the Linnean Society of New South Wales, vol. iv., p. 388. 



A paper devoted to rectification of the nomenclature of 

 some Australian marine shells, with the study of which Mr. 

 Brazier's name is so intimately associated. 



Corbula veuusta Angas, is renamed Smithiana, the former 

 being pre-occupied by Dr. Gould for a Japanese species.
