86 FORAMINIFERA OF THE CRAG. 



Despite the remarks qxioted 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 frond if or mis, P. variata, 

 P. gihba, P. comflanata, P. communis, TextiJaria gihbosa, BilociiUna ringens, &c. ; 

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

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

 fawperafa, 6 mm. long, D. obliqna, 7 mm. long, Polymorphina nodosaria, 4 mm. 

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

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

 Nonionina 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 Diseorbina 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, 



6. Gedgrave. — Zones f, g, and li. 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. 



Surface soil ....... 



Zone h. Saudy buif-coloured Coralline Crag (part of zone g reconstructed ?) . 2' 0" to 3' 0" 



(Buff to yellow Coralline Crag, " the rock bed," a soft friable building^ About 17' 0" to 

 stone in three distinct beds, false-bedded throughout, full ofV bottom of pit ; 

 Bryozoa and shell detritus J base not seen. 



Pit at Low Farm, Gedgrave, close to the marshes, showing in part the 

 downward succession of the High-Hovise pit. 



Yellow sandy Coralline Crag, of the usual characters, but even-bedded in 



part ; full of Bryozoa and MoUusca . . . . 3' 6" to 4' 0" 



Zone f.J Pale buff-coloured Coralline Crag, current-bedded; full of small MoUusca, 

 Erato, HaiMtoma, Cmcum, Trivia, Eulima, Nueula, Psammobia, Luci- 

 nopsis, &c., with many species of Foraminifera . . .3' 0" 



Base not seen. 



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

 exposure of this bed, with Foraminifera and small MoUusca. 



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

 striking, e.g. Textilaria agghdinans, T. gibhosa, Polymorphina variata, P.frondi- 

 formis, P. compressa, P. complanata, together with large, but rarer, Biloculina 

 ringens, &c. Speaking generally, the Foraminifera are closely allied to those
