 interesting series of thin-shelled, elongate, and highly-coloured Cardium edtile, from 

 Shurmish Kul, Jaman Klich, and Jaksi Klich, three large lakes formed by the 

 drying up of the Aral Sea, where they have accustomed themselves to the brackish 

 water, and occur in company with Adacna vitrea, Neritina fltiviatilis, Dreissensia 

 polyinorpha, Hydrohia nlvce, etc. ; (<f), Cardium edule from Lake Mareotis, the 

 Bitter Lakes, Suez Canal, Port Said, and the freshwater lakes at Ramleh, all shew-
