105. Bulimina ovulum, Reuss. Abundant. 



106. Bulimina brevis, D'Orb. In great abundance. 



107. Bulimina intermedia, Reuss. Rather rare. 



108. Bulimina regularis, sp. nov. Jones, MS. (near B. marginata, B'Orb.). 

 Only one good example found. 



109. ? Bulimina, sp. Very rare. 



1 10. Virgulina tegulata, Reuss, VAR. In great abundance. 



111. Bolivina decorata, sp. nov. Jones, MS. Very abundant. 



112. Bolivina, SP. Exquisitely delicate form. Only one specimen found. 



113. Pleurostomella fusiformis, Reuss (" Westphalia"). Rare. 



114. Planorbulina* exsculpta, Reuss (" Westphalia"). Frequent. 



115. Planorbulina ammonoides (Reuss). In the greatest profusion. 



116. Planorbulina ammonoides (Reuss), var. with extra shell-growth, 

 making astral overgrowth on the umbilicus. In great profusion. 



117. Planorbulina crenulata (Reuss), ("Gaas," PI. II. fig. 2). Rather 

 rare. 



118. Truncatulina lobatula ( W. & J.). Frequent. 



119. PULVINULINA MlCHELlNlANA (D'Orb.) var. Frequent. 



120. Rotalia ORBICULARIS {B'Orb.), var. In great profusion. 



121. Rotalia vel planorbulina? PI. III. fig. 18. A Rotaline form, like 

 R. orbicularis in shape, but having each chamber symmetrically perforated 

 with a large central aperture on the outside. Only one specimen found . 

 Prof. T. Rupert Jones says: — "This specimen is of great interest, when 

 considered with the few other known open-chambered Foraminifera. 

 Ehrenberg figures ( ' Mikrogeologie, ' PI. XIX. fig. 8), a Pulvinulina (?) 

 having a symmetrical series of holes, one at the base of each chamber, 

 around the large convex central chamber ; and he figures some Rotalia 



* Prof. W. K. Parker, F.R.S., has kindly favoured us with his opinion on the Rota Una. 

 and some of the more obscure of the other Foraminifera of this list.
