3^3 Tertiary Foraminifera 19 



Horizon and locality . — Miocene; James river, Va. 



Geological distribution . — Tertiar}- . 



The genus Textularia is represented by several species in 

 the James River Miocene. The material from which the For- 

 aminifera were extracfled came from the bluffs at Grove's Landing. 



Textu!aria agglutinans.

 figs. 1-3, var. figs. 4 and 12, 1884. 

 Test agglutinous, elongated, tapering onl}' slightly, of a dull

 ed, chambers numerous, nine or ten in each series, septa some-

 Textularia articulata. 

 vSyn. TextulaiHa articulata d'Orhigny, Foram. Foss. Vien., p. 250, pi, xv, 



figs. 16-18, 1846. 

 Test broad, laterally compressed, tapering only slightly tow- 

 ard the posterior end which is slightly rounded; peripheral mar- 

 gin sharp and provided with a marginal keel encircling the 

 sides of the whole shell; chambers numerous, about ten in each 

 series, separated by straight or only slightly curved septa; aper- 

 ture a small median opening along the mner margin of the 

 final segment; length 0.65-0.86 mm. 



The above species is closely allied to Textularia carinata 

 d'Orbigny but differs in the absence of marginal irregulari- 

 ties and spines, and the sutures are not quite as limbate. 

 Horizon and locality. — Miocene; Plum Point, Md. 

 Geological distribution. — Middle and Upper Tertiar}'.
