= Dr. Gray informs me that Cailliaud figures a species near to this from Egypt, which is in his 

 possession, but I have not seen the shell or description. A specimen in Mr. Tanner's collection labelled 

 Iridina arcuata, Caill., and sent by M. Cailliaud to the late Mr. Hyde, is an Anodonta. 



* In Denham and Clapperton's Journey. 



* The figure is very like rubens, hwi Prof. Krauss says it differs (" Siidafrikanischen MoUusken"). 

 It comes from Natal, South Africa. 



^ A specimen of ceelestis received of Dr. Pitcairn, from Edinburgh, was marked Unio longinus. Gray.
