MiLioLA (QuiNQUELOCULINA) TENUIS, Parker and Junes, 1865. Phil. Trans., vol. civ., 



p. 411, pi. 17, fig. 84. 



Characters. — Nearly complanate, but often curved, thin, more or less unsymmetrical; 

 presenting an extreme enfeeblement of Q. seminulum, Spiroloculine in aspect, and twisted 

 on itself. 



Q,. tenuis is small and very rare in the Crag of Sudbourne (specimen lost). It lives in 

 the Atlantic and Mediterranean, at considerable depths. It is fossil in some Tertiary beds 

 of Germany, and in the Lias of England. 



1 We regret much that we have been compelled to make the remark " specimens lost," in connection 

 with several species, one or two of them amongst the rarest of the Crag Forarainifera. We may explain, 

 that quite recently, since the plates which are appended to this Monograph were engraved, we had picked 

 out of our latest gatherings specimens of all the forms which had not been drawn, intending to make from 

 them a fifth plate. The specimens were packed and sent by post, with a view to their being placed in the 

 engraver's hands, but the parcel miscarried ; and, notwithstanding the careful inquiries of the Post-Ofiice 

 authorities, which we are bound to acknowledge, it has not been heard of since. Except in the necessary 

 omission of figures, and, in one or two cases, the want of details of measurement, the accuracy of the letter- 

 press is not affected by the loss.
