H. W. Burrows — Crag Foraminifera. 509 



are very large and well grown ; and the same remark applies to 

 JPuJvinulina repanda. Cassidulina Icevigata, not visually a common 

 form in the Coralline Crag, is also fairly plentiful in this zone. In 

 zone e we notice the same abundance of FoJystomella crispa, large 

 and well developed. Other common species are Textilaria sagittula, 

 Truncatulina lobatuJa, T. Haidingeri, and Rotalia Beccarii. On the 

 other hand, NonionirxB are rare and small. Milioline forms are 

 remarkably absent. 



3. Sndhourne Hall. — Under the surface soil and drift (1-| feet) ; 

 zone d, 6^ feet. 



This pit is referred, somewhat doubtfully, by Prof. Prestwich to 

 the zone d ; but the Mollusca, especiall}' the band with Arctica 

 islandica, in a greenish to bufif-coloured Crag, so distinctive of this 

 zone at Broom Hill, Sutton, and elsewhere, together with the 

 Foraminifera, confirm this view. Some of the latter are here very 

 fine; specimens of Polymorphina frondiformis 5mm. long, and of 

 P. complnnata 4 mm. long, are not uncommon. Polijmorphiiia 

 variata is also plentiful and well grown, together with Textilaria 

 agglvtinans (varieties) and T. trochvs. 



4. Tattingstone {Farlc Farm) ; zone d. — Prof Prestwich kindly 

 supplied some material from the outlier of Coralline Crag occurring 

 in this locality, four and a half miles south-south-west of Ipswich. 

 The section is now much overgrown ; but originally, beneath 12 feet 

 of Red Crag, about 8 feet of Coralline Crag were exposed. This was 

 referred with some doubt by Prof Prestwich to his zone d; and the 

 foraminiferal fauna differs somewhat from that referable to this 

 zone in other localities. Lagence are fairly plentiful ; L. Incunata 

 and L. melo, not often met with elsewhere, being rather common. 

 Excepting some species which range through the entire formation, 

 Foraminifera are rather rare. 



5. Sutton; zones e, /, and g. — The pits in this classical locality are 

 now somewhat obscured, weathered, and overgrown. The celebrated 

 Bullock-yard pit, about 250 yards south-west of Pettistree Hall, 

 furnished the late Mr. S. V. Wood with the bulk of his extensive 

 collection of Mollusca from this formation. In 1894 a comparatively 

 fresh excavation, some forty to fifty yards north of the Bullock-yard 

 pit and facing Pettistree Hall, showed : Under the surface-soil (2 feet); 

 zone gr, 2 to 3 feet ; zone /, 5 feet ; zone e, 4|^ feet. The strata are 

 in all probability lenticular and unevenly bedded. Here the zones 

 e and / have yielded a rich foraminiferal fauna. The latter gives 

 Polymorphina frondiformis, P. variata, P. gibba, P. complanata, P. 

 communis, Textilaria gibbosa, Biloculina ringens, etc. ; while the 

 Lagence, rarer as individuals, are numerous in species. Dentalina 

 pauperata, 6 mm. long, D. obliqua, 7 mm. long, Polymorphina nodo- 

 saria, 4 mm. long, and Dimorphina tuberosa, 4 mm. long, are not 

 infrequent. In zone e the species common in the same zone at 

 Broom Hill are also plentiful here; and Nonionina scapha, rather 

 rare there, is very common here and well developed. Miliolina are 

 rather common, together with Planorbulina Mediterranensis and 

 Discorbina rosacea.
