8. Trilociilina suhorbi'cuhin's, D'Orb. 



TriloatUtia ttuhorhiciiluris, D'Orb. Ann. .Sci. Nat. vol. vii. p. 300. no. 12; 

 Foram. Cuba, p. loO. no. 'J4, pi. 10. tigs. 9-11. 



" Hah. Fossil at Ciistcl-Arquato : recent in sauds from the 

 Antilles." 



D'Orbigny figures in tlie Cuba ^Monograph tlirce Triloculine 

 Miliolir\, all with .surtace-oniauK-iitation ot" delicate, parallel, 

 longitudinal stria^, viz. Triloculina Broiujuiartiaiui, Tr. 

 Fichteliana, and Tr. snborhiculans. These ditfer only in that 

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

 by the greater or less ventricosity of the individual cham- 

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

 Broiigniartii, the term applied by D'Orbigny to Soldani's 

 figures. 



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

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

 proaching Keuss's genus ChihstomeUa in form. 



Some Soldanian figm*es and some of the illustrations of the 

 * Tableau Methodique ' are referred to in the Cuba Monograph 

 with respect to the following species ; a detailed account has 

 been previously given of each of these : — LingiiUna carinata, 

 pi. 1. figs. 13, 14; Cristellaria creindxda^ pi. 8. figs. 17, 18; 

 Orhicidina niunismalis^ pi. 8. figs. 4-16 ; Rotalina \PJnnorlm~ 

 Una] rosea, pi. 3. figs. 9-11 ; Rosalina Parlcinsoniana [liotah'a 

 Beccarii], pi. 4. figs. 25-27 ; Calcarina calcar, pi. 5. figs. 22-24; 

 Planorhulina vidgaris {mediterranensis in ' Tabl. Moth.'), pi. 6. 

 figs. 11-15; Trilocidina ohlonga, pi. 10. figs. 3-5; and 7Vi- 

 locidina Brongniartiana (callecf Tr. Brongniartii in the ' Tabl. 

 Mah.'), pi. 10. figs. 6-8.
