Panama Shells. 



PURPURID^E. 



. In searching for species of this genus, I had 

 but little success, although all the sands near Panama were 

 visited, from the low water mark of the spring tides upwards. 

 Of the ten species which were obtained, only one was found 

 alive. Probably the species appear chiefly at certain seasons. 

 The one which was found alive in countless mvriads, was seen 



it 



during only a part of my stay in Panama.
