TEXTULARID^. 



TEXTULARINyE. 



Textularia, Defrance. 



*Textularia concava, Karrer, sp. (PI. 1, fig. 11.) 



Plecanium concavum, Karrer ('68), p. 129, pi. 1, fig. 3. 



Textularia eoncava (Karrer), Brady ('84), p. 360, pi. 42, 

 figs. 13, 14, and pi. 43, fig. 11. 



The specimens are built up of fine sand grains, and 

 are of a pale buff colour. They vary as to the squareness 

 of the edges, but all have the lipped orifice. Rare. 



*Textularia agglutinans, d'Orbigny. 



Textularia agglutinans, d'Orbigny ('39), p. 144, pi. 1, 

 figs. 17, 18, 32-34.

 281-284, 294-296. 



The specimens vary greatly, and only a few can be 

 considered typical. Many of them at the commencement 

 have the chambers more or less flattened, and their edges 

 acute, while the oral end is slightly compressed, whereas 

 in others *(P1. 2, fig. 1) the test approaches d'Orbigny's 

 figures of T. candeiana ('39), pi. 1, figs. 25-27. Very 

 frequent.
