Unlimimi j, iijii Terquem, 1882, Mem. Soc. Geol. France, ser. 3, vol. ii. Mem. 3, 

 p. 116, pi. xii. fig. 18. 



One specimen only. Fossil. Terquem's species, although 

 obviously closely allied to B. elegantissima d'Orbigny, is yet suffi- 

 ciently distinctive to merit separation. His figure differs from 

 B. elegantissima in its more regular contour and neatness. The 

 shell is almost cylindrical in shape with rounded extremities, and 

 only one series of chambers is visible, externally wound in an 

 elongate spiral round the central axis. The sutures are flush with 

 the surface of the shell and the "comma" shaped aperture is set 

 on the flat face of the final segment. 



Terquem's specimens were fossils from the Eocene of Vaudan- 

 court, " very rare." 



333. lhilimimi selseyensis sp. n. 



(Plate X. figs. 1, 2.) 



The specimen figured is a fossil, and was at hrst regarded as an 

 abnormal specimen of Uvigerina selseyensis (Heron- Allen and Ear- 

 land), but closer examination having determined the entire absence 

 of Uvigerine aperture and the presence of a distinctly Bulimine 

 opening on the side of the shell, we can only regard it as a Buli- 

 mine isomorph of that species, from which it differs externally in 

 its broader and stouter build. It consists of four or five convolu- 

 tions of heart-shaped chambers arranged round a spiral axis, the 

 narrow ends being disposed towards the oral end of the shell. The 

 sutural lines were deeply undercut as in IT. selseyensis. The species 

 is possibly of much more frequent occurrence than is apparent, as 

 specimens would be readily confused with IT. selseyensis, which is 

 very common. 



Length, 0'25 mm. Greatest breadth, nearly 0-2 mm. 



Bulimina striato-punctata Terquem. 



' Bulimint striato-jmnctata Terquem, 1882, Mem. Soc. Geol. France, ser. 3, 

 vol. ii. Mem. 3, p. 116, pi. xii. fig. 19. 



This form is also obviously near to B. elegantissima (d'Orbigny), 

 but is characterized by the foramina being placed in regular lines, 

 so that there is a superficial appearance of external striation. The 

 sutures are flush and the sides of the shell are almost parallel, the 

 aboral end being a blunt cone and the aperture set on the flattened 

 face of the terminal chamber. 



Terquem's specimens were Eocene fossils from Septeuil, near 

 Paris ; " very rare." 



We have several specimens, obviously fossil, which may be 

 referred to this species, as they possess the linear punctation charac- 

 teristic of Terquem's form.
