TRANSACTIONS OF WAGNER 



TERTIARY FAUNA OF FLORIDA 



Claibornian; T. (Angulus) plana Lea, 1833 (+ Donax plana Gregorio). 

 The numbers of the figures of this species and T. ovalis, both in text and on 

 the plate, in Lea's " Contributions to Geology" are reversed; Egeria plana is 

 represented by figure 24, and E. ovalis by figure 25, as clearly denoted by their 

 respective descriptions. As there was already a Tellina plana, d'Orbigny 

 changed this specific name to sub plana in 1850, Claibornian; T. (Arcopagia) 

 Raveneli Conrad, 1846 (a fine and typical Arcopagia, externally recalling 

 Semele linosa; Conrad refers to a figure on Plate v., but I have never found 

 a copy of this plate, though the description is quite recognizable), Claibornian; 

 Macoma scandula Conrad, 1834, Claibornian; T. (Metis?} Sillimani Conrad, 

 1846, Claibornian; T. (Angulus) subtriangularis Aldrich, June, 1895 (not T. 

 Williamsi Clark), Chickasawan; T. (Arcopagia) tallicheti Harris, 1895 (com- 

 pare T. papyria Conr.), Claibornian; T. (Arcopagia) Trumani Harris, 1897, 

 Chickasawan; T. (Peronidia?) Williamsi Clark, 1895, Maryland; and T. 

 (Angulus) virginiana Clark, 1895 (not identical with subtriangularis Aldrich), 

 Maryland; T. subequalis Conrad, 1848, unfigured and described from a cast, 

 is unrecognizable. To this list a few species can now be added from the 

 collections of the United States Geological Survey. 



Tellina (Angulus) entaenia n. sp. 

 PLATE 46, FIGURE 2. 



Eocene of the Claiborne sands at Claiborne, Alabama; Frank Burns. 



Shell small, rather compressed, solid, elongate, very inequilateral; beaks 

 low, surface polished, sculptured with faint, little elevated, somewhat irregular 

 concentric lines, which at about the posterior third become suddenly stronger 

 and more prominent, and on the posterior dorsal slope become about half as 

 numerous, somewhat irregular, and still more elevated ; hinge normal, nymph 

 for the ligament short and prominent; pallial sinus short, rounded in front, 

 reaching a little before the middle of the valve and below about half con- 

 fluent with the pallial line; a faint ray behind the anterior adductor scar. 

 Lon. 9, alt. 4, semidiam. 0.8 mm. 



Nothing like this interesting little shell has been described from this 

 horizon. Two left valves were obtained. The prominence of the nymph is 

 a general characteristic of the subgenus Angulus, though I note in several 

 European publications this feature does not appear to be understood, and 

 there has been a tendency to refer such forms to Psammobia, apparently on 

 this character alone.
