Noticed in previous papers, especially in Phil. Trans, vol. civ. 

 pp. 365 &c. 



Fig. ZT seems to be a few-celled Glohigerina ; so also fig. M. 

 Indeed, excepting fig. K {CassidtiUna) , all the figures of pi. 123 

 are Glohigerinw, and all of pi. 124, except perhaps fig. Z; also 

 all of pi. 125, and half of those of pi. 126. 



82. Glohigerina elongata, D'Orb. PI. XL fig. 129.

" Hab. Recent in the Adriatic, near Rimini ; fossil at 

 Castel-Arquato." (Mediterranean, Soldani.) 



Though these two figures of the minute specimen are rude, 

 and, owing to the nature of the engraving, there is no indica- 

 tion of the texture of the shell, we have no hesitation in 

 assigning these figures to the genus Cassidulina ; the aperture 

 and general arrangement of the segments equally point to this 

 conclusion. They may j)erhaps be best placed with C. oh- 

 longa. 



83. Glohigerina helicina, D'Orb. PI. XI. fig. 113.

^^ Hah. The Adriatic, near Rimini." (Mediterranean and 

 Adriatic, Soldani.) 



A large, many-chambered, lobular variety, which we have 

 found convenient to retain. (Fig. qq is copied.) These show 

 a tendency to have bilobate segments, whilst No. 81 shows 

 trilobation.

Not separable from the Gyroidina orbicularis of the
