" Hah. Fossil at Castel-Arquato ; recent in sands from the

iT?-'9^^^^"^ figures in the Cuba Monograph three Triloculine 

 Mihola>, all with surface-ornamentation of delicate, parallel, 

 longitudmal strise, viz. TrilocuUna Brongmartiana, Tr. 

 Fichteliana, and Tr. suborhicularis. These differ only in that 

 ever variable character, the contour of the test, as determined 

 by the greater or less ventiicosity of the individual cham- 

 bers. We propose to include all these under the term T. 

 Brongmartiij the term applied by D'Orbigny to Soldani's 

 figures. 



We may here note that figs. 12-14, pi. 10 {TrilocuUna 

 labiosa, D Orb.), represent a Milioline form very closely ap- 

 proachmg Reuss's genus Chihstomella in form.

 been previously given of each of these '.—LinguUna carinata,
