Upper Bavarian Alps/'' H. meridionale, however, is very much 

 larger, is less elongate in the lateral aspect, and the test is somewhat 

 clearer or more translucent, and white. It is fairly frequent in the 

 washings. 



Family TEXTULAEIID^. 



Genus BULIMINA d'Orbigny. 



BuLiMiNA TEiGONULA nom. nov.f var. inobnata nov. 



Plate XXIX., fig. 3. 



The test is formed on the type of B. clegans d'Orbigny, that is, 

 more or less regularly trigonal. The salient edges are more pro- 

 nounced than in that species, and not so sharp as in B. trigomda 

 {trigona) Chapman. It most closely approaches the latter form in 

 general outline, but the aboral end is not studded with granulations, 

 the surface being quite smooth. 



The specific form B. trigomda {trigona) has been found in the 

 Taplow Chalk, zone of Belemnites {Actinocamax) quadratus,\ and a 

 smooth form more nearly resembling our present variety was 

 obtained from the Cretaceous marl of the Upper Bavarian Alps by 

 Dr. Egger.j 



Only one specimen of B. trigomda has been found amongst the 

 present series from the Cretaceous of East Pondoland.

t The specific name trigona has already been used by Tei-quem to denominate a 

 foraminiferal species of the genus Bulimina (Mem. Soc. Geol. France, ser. 3, 

 vol. ii., 1882, p. 110, pi. xi. (xix.), figs. 28, 29), and therefore the specific name of 

 the Taplow Chalk form is here amended to trifjonnla.
