series, septal orifice at the centre of the umbiHcal margin of each 

 segment, close to its line of contact with the preceding opposite 

 segment. Aperture simple or labyrinthic. (Brady, Monog. Carb. and 

 Perm. Foram.) 



In this family are placed genera whose species seem to be the 

 most abundant of the Carboniferous Foraminifera. Members, too, 

 have the longest range in time. Texhilaria species range from the 

 Silurian rocks to the present seas ; and Valviilina species are very 

 abundant in the chalk detritus of Kent, and are found in the lower 

 and middle Tertiary, and also in the present seas ; while Bigenerina 

 is living in the Mediterranean or Adriatic Seas.

 This species is present in the Carboniferous material of both 

 North Yorkshire and also Northumberland, and it is present, though 

 rare, in my Derbyshire material. It is rather more abundant in the 

 Scotch Shales. I have some very fine examples from several 

 localities.

I have several examples of this species from the Northumberland 

 Shales, but I find that it is rather rare in other English localities. 

 Mr. Brady, however, says (Monog., p. 132): ' By far the larger 

 number of Carboniferous Textularice have the characters of T eximia. 

 In England it is found more or less frequently throughout the 

 Carboniferous series.'
