2 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. 



3 In Denham and Clapperton's Journey. 



4 The figure is very like rubens, but Prof. Krauss says it differs (" Siidafrikanischen Mollusken"). 

 It comes from Natal, South Africa. 



6 A specimen of cselestis received of Dr. Pitcairn, from Edinburgh, was marked Unio longinus, Gray.
