TERTIARY FAUNA OF FLORIDA 



Tellina (Eurytellina) sp. 



Oligocene of the Bowden marl, Jamaica, West Indies. 



Fragments of quite a distinct species of Eurytellina. were found in the marl, 

 but I prefer to merely announce its presence until material fit for figuring is 

 obtained. 



Tellina (Eurytellina) roburina n.sp. 

 Plate 47, Figure 9. 



Oligocene of the Oak Grove sands, Santa Rosa County, Florida ; Burns. 



Shell solid, subequilateral, rather elongate-trigonal, compressed; anterior 

 end evenly rounded, posterior end pointed with a small truncation near the 

 tip ; beaks inconspicuous, pointed ; lunule short and nearly linear ; dorsal slopes 

 nearly rectilinear ; surface of the disk polished, closely, evenly, concentrically 

 grooved, sublamellose on the posterior dorsal area, which exhibits an obsolete 

 fold and slight flexuosity; hinge as in Angnlus, teeth well developed; valve 

 thickened on the inner margin of the adductor scars ; pallial sinus elongate, 

 low, squarish at the anterior end where its distal angle nearly touches the 

 adductor scar, wholly confluent below. Lon. 39, alt. 22.5, diam. 8 mm. 



This is a fine species, a precursor of T. angulosa Gmelin, T. rubescens 

 Hanley, and similar recent forms. 



Tellina (Moerella) Simpsoni n. sp. 



Plate 46. Figure 12. 



Oligocene of the Bowden marl of Jamaica ; Henderson and Simpson. 



Shell small, inflated, equivalve, very inequilateral, polished ; anterior dorsal 

 slope rectilinear, anterior end rounded, base convexly arcuate ; posterior end 

 very short with a sudden constriction, slightly flexed, with the extremity 

 bluntly pointed ; beaks low, somewhat opisthogyrous, with a perceptible lunule ; 

 hinge normal, pallial sinus extending nearly to the anterior adductor scar, 

 mostly confluent below. Lon. 7, alt. 5, diam. 4 mm. 



This form is what Gabb identified as T. cuneata d'Orbigny, but the latter 

 is less inflated and less flexuous behind. T. Simpsoni sometimes appears per- 

 fectly smooth, but other specimens show incremental sculpture. 



Tellina (Moerella) Hendersoni n. sp. 



Plate 46, Figure 5. 

 Oligocene of the Bowden marl of Jamaica ; Henderson and Simpson. 

 Shell small, moderately convex, very inequilateral; form resembling the 

 preceding species but less inflated, more regular, with the posterior end not
