This, the prince of Oriental Uniouidcr, is not uncommon in the 

 Orontes. I found a dead valve by the Leontes, but did not meet with it 

 in the Lake of Galilee. From its brilliant purple hue, which is preserved 

 in the most worn valves, from its size, its jet-black epidermis, and the 

 peculiar compression, it is a remarkable and isolated species. I can find 

 no Unio in the collection of Mr. Cuming which at all resembles it.
