PAET II. 



I. INTRODUCTORY REMARKS. 



Part I of the Monograph of the Foraminifera of the Crag was unavoidably 

 left unfinished in 18(36. Two of the joint authors have unfortunately been 

 removed from among us by death, and their fellow-worker has been hindered by 

 many circumstances hitherto from completing the Monograph. 



It is proposed that in Part II 1 additions and corrections, in many cases 

 necessary, be made for the genera and species already dealt with ; and that the 

 descriptive work should comprise such groups as precede Lagena and its allies in the 

 more modern classification. A considerable quantity of MS. prepared by the late 

 Dr. H. B. Brady, after 1866 for this Part II, has been advantageously incorporated. 



Tbe descriptions will be rendered in as short a form as possible by limiting 

 them to concise notes on the characters, distribution, and peculiarities of shape 

 and structure, such as the same authors used in the " Memoir on the Foraminifera 

 of the Abrohlos Bank " (' Trans. Zool. Soc.,' vol. xii, part 7, 1888, pp. 211—239) ; 

 and as Dr. Egger has lately made use of in his " Memoir on the Foraminifera 

 from the Soundings obtained by the ' Gazelle ' " (' Abhandl. k. Bayer. Akad. Wiss.,' 

 vol. xviii, part 2, 1893, pp. 195 — 266), — in each case references to the Report 2 on 

 the Foraminifera brought home by the 'Challenger' being made for the 

 synonymy down to 1884, as far as applicable and convenient. The system of 

 classification, also, and of nomenclature used by Dr. H. B. Brady in that Report 

 will be adhered to as much as possible. This plan has been followed by 

 Dr. Carlo Fornasini ('Boll. Soc. Geol. Ital.,' 1889), by Signor M. Malagoli 

 (' Atti Soc. Nat. Modena,' 1888) and others. 



Having lately had opportunities of studying the original figured specimens 

 of Foraminifera from the Crag — both those formerly in Mr. S. V. Wood's and 

 those in Professor W. K. Parker's Collection — all being now in the British 

 Museuin (Natural-History Branch), we have been able to examine the figured
