REPORT ON THE PORAMINIFERA. 
587 
Sub-family 4. Ramulininse. 
Rcimulina, Rupert Jones. 
Ramulina, Jones [1875], Wright, Brady. 
Test free, branching ; consisting of a calcareous tube, swollen at intervals so as to 
form more or less definite, often irregular segments, from which lateral stolons or branches 
are given off. Texture hyaline. 
In Mr. Wright’s List of the Cretaceous Microzoa of the North of Ireland, 1 figures 
are given of two obscure organisms, under the names Ramulina Icevis and Ramulina 
brachiata respectively. The specimens represented are manifestly only fragments, and 
neither generic nor specific descriptions are furnished beyond the general statement that 
the former ( Ramulina Icevis) is a “ simple, calcareous, subsegmented, branching, 
Nodosarian form.” An opinion is further expressed, on the authority of Prof. Rupert 
Jones, that “the so-called Dentcdina (?) aculeata of d’Orbigny” should be transferred 
to the same genus. 
Those who have devoted much attention to the microzoa of the Chalk must be quite 
familiar with the organisms referred to, though in the fragmentary condition in which 
they are commonly found they may not have been recognised as Foraminifera. There 
can, however, be no doubt of their close affinity to certain forms, still living at moderate 
depths in the seas of tropical and subtropical latitudes, to which the name Ramulina 
globulifera has been assigned. As to the Dentalina aculeata of d’Orbigny, the original 
description and figures, 2 so far as I am able to judge, appear to refer to a common, hispid, 
Dentaline Nodosaria.

Ramulina globulifera, Brady, 1869, Quart. Journ. Micr. Sci., vol. xix., N. S., p. 58, pi. viii. 
figs. 32, 33. 
Test free, branching ; composed of segments of different sizes connected by 
stoloniferous tubes of diverse lengths. Segments from two to eight, or even more, in 
number ; globular or subglobular ; each provided with numerous tubulated apertures, 
radiating from different portions of the periphery, some of which terminate in fresh 
chambers. Stoloniferous tubes narrow in proportion to the bulk of the segments, circular 
in section. Texture hyaline ; surface hispid or aculeate. Length of complete specimens 
xgth inch (1'7 mm.) or more.
