in the Post-tertiary deposits of Norway (Sars. Crosskey and Robertson), and of the 
north-east of Ireland (Wright). 
Uvigerina angulosa, var. spinipes, H. B. Brady (PL LXXIY. figs. 19, 20). 
Uvigerina spinipes, Brady, 1881, Quart. Journ. Micr. Sci., vol. xxi., N. S., p. 64. 
Test resembling that of Uvigerina angulosa in general contour, but not so distinctly 
triangular. Surface smooth, except near the aboral end, which is costate, and terminates 
in a number of short stout spines. Length, -g^rd inch (077 mm.). 
Notwithstanding the very marked characters of some of the specimens, there seems to 
be little doubt that this form, originally described as a distinct species, is nothing more 
than a local variety of Uvigerina angulosa. Some of the shells are nearly cylindrical, or 
at most only slightly compressed on three sides, and they have a smooth exterior, except 
just at the initial end ; but others are more or less angular. 
The single recorded habitat is off Nightingale Island, Tristan d’Acunha, depth 100 to 
150 fathoms. 
Uvigerina porrecta, H. B. Brady (PI. LXXIV. figs. 21-23). 
Uvigerina porreda, Brady, 1879, Quart. Journ. Micr. Sci., vol. xix., N. S., p. 60, pi. viii. 
figs. 15, 16. 
Test elongate, subspiral ; early segments compactly arranged, obscurely triserial ; later 
segments more or less distinct and interrupted, alternating irregularly. Peripheral edges 
of the chambers angular and projecting, more or less serrate ; surface marked by irregular 
longitudinal costae. Aperture situated in a produced tubular neck, usually without an 
everted lip. Length, ^th inch (0'5 mm.). 
This is a coral-reef species, and with one exception all the localities at which it has 
been found lie within the tropics. They are as follows : — off Bermuda, 435 fathoms ; 
Port Louis, Mauritius, harbour-mud ; at three points off the Fiji Islands, 12 fathoms, 210 
fathoms, and 255 fathoms respectively ; off Raine Island, Torres Strait, 155 fathoms ; and 
in the North Pacific, north of Papua, 1850 fathoms. 
Uvigerina brunnensis, Karrer (PI. LXXY. figs. 4, 5). 
Uvigerina brunnensis, Karrer, 1877, Geol. K. F.-J. Wasserleitung, p. 385, pi. xvi .b. fig. 49. 
Under this name Dr. Karrer has described and figured a somewhat slender and 
elongate modification of the Uvigerine type, with granular or slightly hispid surface and
