206 PORAMINIFERA OF THE CRAG. 



we have found it somewliat commonly at Tattingstone, zone d ; and also, but more 

 rarely, at Sudbourne Hall and Broom Hill, zone d ; at Sutton, zone e ; and 

 Gedgrave, zone f. 



Mr. Wright, of Belfast, informs us that this species has been found also on the 

 shore, at extreme low water, at Southport, Lancashire, as mentioned by Mr. G. W. 

 Chaster, in the 'Report Southport Society Nat. Science' for 1890-91 (1892), 

 p. 62 (" L. castrensis "). 



Sub-family 2. — Nodosariin^. 

 Brady, Report ' Challenger,'' 1884, pp. 69 and 488. 



General Characters. — Test polythalamous ; straight, arcuate, or piano-spiral. 



There are but few from among the numerous so-called genera and sub-genera 

 of this family that have to be noticed here. Belonging to the type Nodosaria 

 there are from the Crag only the following : 



1. Glandulina, referred by sorae direct to 



Nodosaria. 



2. Nodosaria (proper). 



3. Dentalina, often regarded as Nodosaria. 



4. VaginuUna. 



5. MargitiuUna. 



6. Cristellaria. 



Ten figures of good examples of noticeable varieties have been added (in 

 Pis. V, VI, and VII) to those noticed in Part I. The lists of synonyms have, of 

 course, greatly increased since 1866. 



The genus Nodosarina (Part I, 1866, p. 46), proposed by Parker and Jones in 

 1859, although scientifically applicable to the manifold series of subtypical forms 

 which it was intended to comprise, has not been widely adopted ; the appellations 

 of the sub-types, such as Glandulina, Nodosaria, &c., being more readily and 

 conveniently used in a quasi-genevic sense. They all also fall into the recognised 

 sub-family of " Nodosariinse." For convenience, therefore, the terms Glandidina, 

 Nodosaria, and others are used here as generic or subgeneric, as in many other 

 memoirs and monographs. It is further most convenient to retain the use of the 

 names of even subordinate sub-types, such as Dentalina, &c., as occasion seems 

 to require, although their slight differential characters are not of real zoological 

 value ; but, just as with other Foraminifera, slight modifications serve to differen- 

 tiate them artificially. 



In the ' Ann. Mag. Nat. Hist.,' ser. 3, vol. iii, 1859, pp. 476, 477, Nodosarina 

 was adopted by Parker and Jones (and by Carpenter, ' Introd. Foram.,' 1862, 

 p. 156) as a broad generic term for the great group of hyaline Foraminifera
