REPORT ON THE EORAMINIEERA.

fathoms respectively; at two in the Southern Ocean, 1570 fathoms and 1950 fathoms; 
at ten in the South Pacific, 1450 fathoms to 2600 fathoms; and at five in the North 
Pacific, 1850 fathoms to 3125 fathoms. 
The specimens described by Hantken were fossils from the Oligocene formations of 
Hungary.

A beautiful little Rotaline, conspicuous amongst littoral Foraminifera by its rosy hue, 
deepening almost to crimson at the centre of the spire. 
Truncatulina rosea is a West Indian species, and has not been observed outside the 
comparatively narrow area originally indicated by d’Orbigny, namely, — the shores of 
Cuba, Martinique, Guadaloupe, St. Thomas, Jamaica, and Haiti. The figured specimen 
is from a gathering' of littoral sand from Cnba, in which the species was particularly 
abundant.

This is a thick, biconvex variety, the chief convexity of the shell being on the 
inferior side. The sutures are limbate externally, especially those radiating from the 
inferior umbilicus, which take the form of stout raised bands of clear shell-substance. 
Truncatulina prcecincta most affects the coral-reefs of the tropics. It has been met 
with off the Philippine Islands, 9 5 fathoms ; and at five Stations amongst the islands 
of the South Pacific, at depths ranging from 15 to 255 fathoms. It also occurs in the 
Red Sea, 30 fathoms. 
Karrer ’s specimens were Miocene fossils from Kostej, in the Banat ; and the occurrence 
of the species in the Miocene and Pliocene of Southern Italy is recorded by Seguenza. 
Truncatulina margaritifera, H. B. Brady (PL XCVI. fig. 2, a.b.c.). 
Truncatulina margaritifera, Brady, 1881, Quart. Journ. Micr. Sci., vol. xxi., N. S., p. 66. 
Test Rotaliform; superior face slightly convex or nearly flat, inferior convex; peri- 
pheral edge sharp, subcarinate, more or less lobulated ; consisting of three convolutions, 
of which the last has about twelve segments ; segments all visible on the superior face,
