long, should perhaps be assigned to T. ahhreviata^ d'Orb., which is 

 distinguished only by its shortness in comparison with its breadth.* 

 T. variabilis and T, difformis are well described by Williamson, 

 and need no comment. 



Bolivma. — In this genus we must place the Textularia Icevigata 

 of Williamson, as it possesses the true Bulimine aperture. Reuss has 

 described a species which appears to be identical, under the name 

 of Bolivma textilarioides^\ but Williamson's specific name having 

 precedence, must stand. 



Amongst the Rotalines we have the species new to Britain, 

 Pulvinulina scittila, Brady, Plate IV., Fig. 12. — One specimen 

 only has been found, and this has been identified by H. B. Brady, 

 F.R.S. We quote his description of the species. | "A variety of 

 Pulvinulijia ca?iarie?ists, difi"ering from the typical form in its 

 relatively small size and compact habit of growth. The margin is 

 rounded instead of sharp and the peripheral ends of the chambers 

 are only slightly convex instead of standing out prominently, 

 as in P. ca7iariensis. Notwithstanding its small minute dimensions, 

 it generally attracts attention by its glistening white appearance." 



NoNiONiNA. — Is represented by an immense number of 

 individuals. Besides the species enumerated in the Catalogue, 

 there are forms closely approaching, if not identical with, 

 N. Boueana, D'Orb., and N. scapha^ F. and M., but these require 

 further study before their exact position can be determined. 



We cannot conclude without expressing our obHgation to H. 

 B. Brady, F.R.S., for the great assistance he has rendered us in 

 determining the species of obscure specimens, and in advising us 

 generally on the difiiculties which have arisen in the preparation 

 of this article.
