OP CONCHOLOGY.

M. Deshayes proposes to change the name to L. Haldemani. 



Physa globosa, Hald. Since employed by Morelet (Journ. de 

 Conch.), 1866. 



Physa scalaris, Jay. This name is also employed by Dunker, 

 1845. Jay's species undoubtedly constitutes the type of a new 

 genus. 



Planorhis Liehmanni, Dunlcer. This species, or a closely re- 

 lated one, is labelled at the Jardin des Plantes with the ticket 

 '■'■PI. rotundatiis, Jan, Texas. Coll. Ferussac." 



PL regularise Lea. Preoccupied by Marcel de Serres, 1818. 



AneyJus Brouetianus, Bourg., is an Algerian species. 



AmpuUaria horealis, Val. = Natica heros, by Valenciennes' 

 own writing upon the margin of a copy of his work in the pos- 

 session of M. Crosse. 



Paludina multicarinata, Haldeman. Valenciennes gave 

 Mexico as the habitat, but the type specimens have the locality 

 " Philippines " attached, in his own handwriting. In the present 

 age no conchologist would be misled on such a subject, because 

 the relations of genera, as well as groups of species of lesser 

 value, to the countries which they inhabit, are more clearly un- 

 derstood. 



Paludina lineata, Klister, is restored by Mr. Binney in place 

 of his own P. contectoides. He explains the cause of the mis- 

 take, into which he was led by a typographical error. 



Paludina lineata, Valenciennes (not Klister). Valenciennes 

 writes on the margin of the copy of his work above alluded to, 

 respecting the locality, — " C'est faux, elle vient de I'lnde." 



Paludina cornea, Val. The type specimens are marked iden- 

 tical with decisa, Say, by Valenciennes himself. 



Paludina castanea, Val., is nothing else but a very large P. 

 achatina.
