86 FORAMINIFERA OF THE CRAG. 



Despite the remarks quoted above, the Sutton pits still yield a rich Rhizopodal 

 fauna, many of the species being fully grown and perfect, occurring in great pro- 

 fusion, notably in zone f, where we find Polymorphina frondiformis, P. variata, 

 P. gibba, P. complanata, P. communis, Textilaria gibbosa, Biloculina ringens, &c. ; 

 while the Lagenae, though somewhat rarer individually, are numerous in species. 

 Some of the specimens are gigantic, comparatively speaking; e. g. Dentalina 

 ■ ■rain, 6 mm. long, D. obliaua, 7 mm. long, Polymorphina nodosaria, 4 mm. 

 long, and Dimorphina tuberosa, 4 mm. loug, are not infrequent. In zone e, the 

 species common in the same zone at Broom Hill are also plentiful here ; but 

 No nionina scapha, which is there somewhat rare, is very common, and the specimens 

 well developed. Moreover Miliolinse are rather common, as are also Planorbulina 

 mediterranensis and Discorbina rosacea. 



It seems probable, therefore, that the greater number of the Foraminifera 

 recorded from Sutton in the First Part of this Monograph were from zone f ; but, 

 if that were not so, it is now impossible to separate those found in zone e. 



G. Gedgrave. — Zones f, g, and h. These zones are well shown in the pits at High 

 and Low Gedgrave, one and a half miles south-west of Orford, in the following 

 sections, measured in August, 1894 : 



Pit close to High House, Gedgrave.

A small pit at Ferry Barn, half a mile to the south-west, also shows a good 

 exposure of tliis bed, with Foraminifera and small Mollusca. 



Zone f. — Tli is is rich in Foraminifera, some of the species being large and 



striking, e.g. Textilaria agglutinans, T. gibbosa, Polymorphina variata, P . frondi-
