TERTIARY FAUNA OF FLORIDA 



onymous with Tellina subradiata Schumacher, but I have been unable to find 

 the place of publication of Schumacher's name, if it has been published. 



An allied species, T. (Eurytellina) rubescens Hanley, now living in West 

 Mexican waters, occurs in the Pleistocene of San Pedro, California. 



Tellina (Eurytellina) scapha n. sp. 

 PLATE 47, FIGURE 16. 



Upper Miocene at Lee's wharf, Nansemond River, near Suffolk, Virginia ; 

 Burns. 



Shell thin, light, moderately convex, inequilateral, the anterior end longer, 

 higher, evenly rounded; the posterior end short, attenuated, with an obsolete 

 fold, vertically rounded-truncate; beaks low, lunule and escutcheon obsolete; 

 surface smooth or marked only with incremental lines a little stronger on the 

 posterior dorsal area ; hinge normal, hinge-line thin, pallial impressions obscure, 

 the sinus probably falling short of the anterior adductor scar. Lon. 30, alt. 

 16.5, diam. 7 mm. 



A single left valve was obtained by Burns which has the aspect of a Eury- 

 tellina. In form it resembles Conrad's dubious Tellina arctata, but wants the 

 broad hinge-plate and concentric elevated lines. 



Tellina (Merisca) calooeana n. sp. 

 PLATE 47, FIGURE 2. 



Pliocene marls of the Caloosahatchie River, Florida, near the site of Fort 

 Thompson ; Ball. 



Shell small, plump, ovate, slightly inequivalve, nearly equilateral, slightly 

 flexuous behind, but hardly rostrate, posterior dorsal area marked by a shallow 

 sulcus ; beaks pointed, conspicuous, a well-marked lunular impression in front 

 of and escutcheon behind them ; surface covered with small, sharp, regularly 

 spaced elevated concentric lamellae ; upper part of the pallial sinus connecting 

 the adductor scars, the lower part wholly confluent with the pallial line. Lon. 

 8, alt. 6, diam. 3 mm. 



This little shell differs from the young of ccquistriata by its inflation ; from 

 T. martinicensis d'Orbigny, its nearest ally, by its more crowded surface lamel- 

 lation and the form of the pallial sinus, the latter in the recent shell failing 

 to reach the anterior adductor scar and running for some distance, after turn- 

 ing, nearly parallel with the pallial line below, before becoming confluent with 

 it.
