From the preceding list it appears that about four hundred and sixty- 

 three generic and subgeneric names have been rightly or wrongly asso- 

 ciated with the group of Brachiopoda. Eighty-seven liave been assigned 

 to the Terehratulkkc, sixty-five to the EhynchoneUidcc as generally under- 

 stood, fifty-three to the Splriferidw, and fifty-two to the StropJiomenidce. 

 Of all these, only about one hundred and thirty have been at all generally 

 accepted, being about three and a half names to each group. Sixteen 

 families and two orders are here recognized. The general list contains 

 about seven hundred names. It is estimated that there are about ten 

 thousand names and synonymes which have been used in the sub-king- 

 dom of Mollvsca, taken in its extended sense, of which the Brachiopods 

 contribute about six per cent.
