1 Mr. 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 Mr. Hyde, is an Anodonta. 



2 The figure is very like rubens, but Mr. Krauss says it differs. It comes from Natal, South Africa. 



3 A specimen of ceelestis received of Dr. Pitcairn, from Edinburgh, was marked Unio Longinus, Gray.
