718 MR. E. CHAPMAN ON THE BARGATE BEDS OF SURREY. [Nov. 1 894, 



with the recent forms found in moderately deep water, and figured 

 by Dr. Brady (loc. cit.), and to regard the Dentalina aculeata of 

 d'Orbigny a as a true Nodosarian form. 



A fragmentary specimen of the cylindrical portion of R. globulifera 

 was found in the Pebble-beds, Littleton ; and a similar one in the 

 Pebble-beds in Halfpenny Lane, Chilworth.

This species is met with in various Cretaceous and Tertiary beds, 

 as well as in recent deposits. 



The four specimens from the Bargate series are small, but are 

 distinguishable from the more typical G. cretacea by the turbinoid 

 form of the spire. Three come from the Pebble-beds, Littleton, 

 and one from the Pebble-beds, Halfpenny Lane, Chilworth. 



110. Globigerina cretacea, d'Orbigny.

 p. 34, pi. iii. figs. 12-14. 



This well-known and common Cretaceous species is represented in 

 the Bargate series by three specimens, from the Pebble-beds, 

 Littleton. 



Family EOTALILD.E. 



Subfamily Botalin-E. 



Patellina, Williamson. 



111. Patellina corrugata, Williamson. 



P. corrugata, Williamson, ' Rec. For. Gr. Brit.' 1858, p. 46, 

 pi. iii. figs. 86-89. 



This interesting little species has hitherto been found in the 

 post-Tertiary beds of Scotland and Ireland, and, as a recent form, 

 usually affects shallow water. 



It is somewhat remarkable to find this small and delicate species 

 in strata as old as the Neocomian, since the various species known 

 from fossiliferous beds of Cretaceous and early Tertiary ages are of 

 a stronger and larger build. 



Five specimens from the Pebble-beds, Littleton ; and two from 

 the Bargate Beds, Holloway Hill.
