Page 18, itoie. The autlior lias been informed by Prof. KiiUiker that he did not employ the term " nucleus " in its technical 

 signification, but that by the terms "cortical" and "nuclear" substance he meant only what is described in the text as "ectosarc" 

 and ** endosarc." 



Page 53, line 20, the words " the duplication of the septal jiartitions " to be omitted ; the author having found since 

 writing them that this structm-al feature is limited to the higher types of the hyaline Foraminifera, instead of being comnmn (as he at 

 first believed) to the whole series. 



Page 105, last five lines. In here stating Cyclolina to he a variety of OrbitoUles, the author was misled by Mr. Carter, who 

 had described under the name Cyclolina a fossil which (as he has since discovered, p. 230, «ofc) does not really accord with 

 D'Orbigny's type of that genus. Mr. Carter's Cyclolina is a true Orbitolites, as stated in •; 186 ; but D'Orbigny's Cyclolina is 

 probably a Fatellina (p. 233). Further, of the forms to which D'Orbigny's designation Orbitolina has been applied, a ))art seems 

 referable to the genus Tinoponis, and another part to Fatellina, as explained in the account of those genera.
