TERTIARY FAUNA OF FLORIDA 



another fossil collected by Haldeman at Vicksburg. It has about twelve ribs 

 and may prove to belong to V. Cossmanni, but for the present it seems best to 

 list it separately in the hope of obtaining more perfect specimens. 



Verticordia (Trigonulina) Cossmanni n. sp. 



fVerticordia eocensis var. O. Meyer, Bericht Senck. Ges., 1887, p. 16. 

 Verticordia eoccenensis Cossmann, Notes Compl., p. 7, pi. i., fig. 6, 1894. 



Eocene of Jackson, Mississippi, O. Meyer ; Oligocene of the Chipola beds, 

 Calhoun County, Florida, Burns. 



The species figured by my friend M. Cossmann, on the authority of Meyer, 

 as that of Langdon is quite distinct from V . eocenensis and even belongs to a 

 different section of the genus. It is, in fact, a Trigonulina, while V . eocenensis 

 is a typical Verticordia. I am not quite certain that the Chipola form is specifi- 

 cally identical with that from Jackson so well figured by M. Cossmann, but it 

 is certainly very closely related to it, and I prefer, for the present at least, to 

 consider them as conspecific. 



Verticordia (Trigonulina) bowdenensis n. sp. 



Verticordia ornata Guppy, in coll., not of Orbigny. 



Oligocene marl of Bowden, Jamaica ; Vendryes and Henderson. 



Shell small, rotund, rather convex, with eight or nine anterior radial ribs 

 with deep, subequal interspaces, then a wider space followed by two adjacent 

 ribs, then a much wider space with another adjacent pair beyond it separated 

 by a smooth area, larger in the left than in the right valve, from the posterior 

 margin ; the surface when intact is covered with minute granules arranged in 

 rows harmonizing with the ribs ; lunule very deeply impressed in the left valve, 

 less so in the right; tooth of the right valve large and strong, the posterior 

 margin of the left valve modified to form a lamina or lateral tooth received in 

 a groove of the opposite valves. Lon. 2.7, alt. 2.6, diam. 2.0 mm. 



Very similar to V. Cossmanni but more plump and orbicular.
