Yol. 50.] MR. E. CHAPMAN OK THE BARGATE BEDS OF STXRREY. 705 



Bargate Beds are not quite typical, but the difference is so slight 

 that it» appears to he worth no varietal distinction. In Ehrenber- 

 gina pupa the conformation of the test can he compared with a 

 Bulimina which has been flattened or stretched out in its widest 

 direction, the two lateral margins folded together, and the test 

 coiled vertically upon itself. The Bargate specimens exhibit the 

 longitudinal folding, but not to so marked an extent as in recent 

 examples. The species has not been before recorded in the fossil 

 condition. 



Three specimens from the Pebble-beds, Littleton.

L. globosa is known from beds of Jurassic age upwards. It is 

 represented in the present series by six specimens, one of which is 

 pyriform, whilst the remaining five are subglobular. Pour were 

 found in the Pebble-beds, Littleton, one (silicified) in the siliceous 

 residue of Bargate limestone from Halfpenny Lane, and one in the 

 Pebble-beds, same locality.

L. apnculata, Brady, ' Challenger ' Rep. vol. ix. (1884) p. 453, 

 pi. Ivi. figs. 4, 15-18. 



This species is known from the Lias and many fossiliferous beds 

 of later date. It is common in the English Gault, and is also found 

 in Cretaceous deposits of North Germany of about the same age. 



The four specimens from the Pebble-beds, Littleton, are all sub- 

 globose in form. 



51. Lagena l^vis (Montagu).

An example of this foraminifer was seen in a thin section of
