litre nt a ml Fossil Foraminifera. 305 



Several specimens, all apparently recent, varying considerably 

 in appearance, and forming a series connecting M. contorta and 

 M. ferrusacii with the extreme development of the type as figured 

 by Brady.

One small fossil specimen, representing an early stage of the 

 shell, and doubtless derived from an Eocene clay. 



33. Articulina foveolata Heron-Allen and Earland. 



(Plate IX. fig. 4.) 



Articulina foveolata Heron- Allen and Earland, 1909, Journ. E. Micr. Soc. p. 317, 

 pi. xv. fig. 8. 



The pretty little fossil specimen which we figure is apparently 

 the early Milioline stage of Articulina foveolata. It possesses a 

 characteristic circular Articuline aperture without sign of tooth. 



The markings are much more regular and pronounced than in 

 the type specimen of the species, which was in a poor state of 

 preservation.

A single fossil specimen, broken, but showing sufficient post- 

 Milioline development for the identification of the species. 



This is a somewhat infrequent constituent of coral sands all 

 over the world, but not uncommon in the West Indian seas. 



As a fossil d'Orbigny records it from the Miocene of Vienna. 



:55. Cornuspira foliacea Philippi sp. 

 (Plate IX. figs. 5, 6.) 



Since our original note Mas written we have found the elegant 

 little specimen which we figure. The shell is semi-transparent, and 

 instead of the normal flatness it presents a curious curvature which 

 is well brought out in the drawing.
