The figures of Paludestrina protea represent the more conspicuous aspects of variation, 

 selected from over 40,000 specimens. Of the Physas more than 2000 were critically ex- 

 amined and compared. 



Some idea of the abundance of these shells on the surface of the desert may be 

 formed from the fact, that about a year after the above paper was published, I had in 

 my hands and weighed a bag which contained fourteen pounds of Paludestrina, quite clean 

 and free from sand or any other shells, except a few examples of Amnicola longinqua; in 

 ether words seven million three hundred and four individuals. See also Nos. 34, 43, ante.
