144 SYNOPSIS OF AMERICAN FOSSIL BRACHIOPODA. [bill. 87. 



ANOPLOTHECA Sandberger (emend Hall)— Continued. 



Obs, Hall aud Clarke have shown that Auoplotheca aud Bilida are synonymona 

 terms and that Cudospira is also structurally identical. 'I'hc latter name, 

 however, they retain as a subgenus of Anoi)lotheca. While the brachydinin 

 is not yet fully known in Leptoco'lia, all its other characters are the same 

 as tho.se of Ciulospira. Under these cinnimstances it appears best, for the 

 present at least, to refer all American 8j)ecies of Leptocudia and Codospira 

 to Anoplotheca.
