South Seas at Rawack ; fossil at Castel-Arquato." (Medi- 

 terranean , So Man i. ) 



A eompactly made Triloculina^ of the angular type, hut 

 lacking the equilateral regularity of T. tricarinata and T. 

 trigonula.

" Hah. lleccnt in the Mediterranean, at the Island of St. 

 Helena, and Shark Bay, Australia." 



If there be any value of subgeneric sort in the number of 

 visible ehambers, the speeimens indicated by these figures 

 belong to QmnquelocuUna rather than Triloculina. 



146. Triloculina inflata, D'Orb. PI. VIII. fig. 16.

" Ilah. Recent in the Mediterranean ; fossil in the neigh- 

 bourhood of Dax, of Bordeaux, and of Soissons, and at Castel- 

 Arquato." (Isola del Giglio, Mediterranean; and Rimini, 

 Adriatic, Soldani.) 



Apparently an irregular loose-growing Qninqucloculina \ 

 but it might with almost equal justice be placed under D'Or- 

 bigny's genus Hauerina. WclI-dcvclopcd specimens of this 

 latter genus are very rare in a recent condition ; whilst ill- 

 grown Quinquelocidinw, like the figures, are common in lit- 

 toral sands and muddy shallows. 



147. Triloculina tricostata, D'Orb. PI. VIII. fig. 20.

" Hah. Fossil in the neighbourhood of Paris." (Mediterra- 

 nean and Adriatic, Soldani.) 



Apparently a young or few-ribbed specimen of Quinque- 

 loculina 2)ulchella. D'Orbigny, in his Vienna-Basin Mono- 

 graph, figures a beautiful example of the same form under the 

 name of Q. Josephina. When the numl)cr of costai modifies 

 to any extent tlie general morphological characters of tlie test, 

 it may become a character of some subordinate value ; but, 

 taken by itself, it entirely breaks down as a specific or even 

 varietal distinction.
