Textularia agglutinans, d'Orbigny. (PI. XIV, Fig. 3.) 



Textularia agglutinans, d'Orb., 1839 : Foram. Cuba, p. 144, pi. i, figs. 17, 18, 32-34. 



A specimen of the above was met with in one of the sections, 



which has the aboral end somewhat more attenuate than is usual 



in the typical form. The texture of the shell - wall is coarsely 



arenaceous, and the limestone in which it occurs was probably 



deposited in quite shallow water.

figs. 14-18. 



A vertical section of a stout bigenerine' form occurs in one of the 

 sections, and is most probably referable to the above species. 

 B. nodosaria has been recorded from various deposits dating from 

 Middle Tertiary times.

The specimen under notice is a vertical section of a narrow form 

 cut at such an angle as to give a chevroned aspect to the chambers. 

 It is possibly referable to the well-known Tertiary species Bolivina 

 punctata, and similar specimens have occurred in both the Libyan 

 and Mokattam Series of Egypt.

Several undoubted specimens of this form were detected in the 

 fine material of the sections made from rock-specimen No. 4,112.
