PUPOIDES. 113 



Length 5.6, diam. 2.4 mm.; 6^ whorls (fig. 6). 



Length 4.8, diam. 2.55 mm.; 5y 2 whorls (fig. 7). 



This broad form occurs in several lots from Cuba and 



dti; also in a lot from Tampico, the shells here being 



taller. 



The Bermudan form may be referable to P. m. nitidulus; 

 it measures 4 to 4.5 mm. long. Specimens seen from Church 

 Cave near Tucker's Town, Fairyland, near Hamilton and 

 Port Royal (S. Brown), Flatts near Frascati Hotel (A. Gu- 

 lick). 



This shell has usually been known as Pupa fallax Say, but 

 that species was based upon a stray example of Ena obscura 

 (Mull.) of Europe. The same specimen, apparently, served 

 for type of Pupa placida Say.
