Cassidulina calabra, Seguenza, sp. (PI. CXIII. fig. 8, a.b.c.). 
Burseolina calabra, Seguenza, 1879, Fonnaz. Terz. Reggio, p. 138, pi. xiii. fig. 7, a.L. 
Prof. Seguenza lias liad the goodness to send to me for examination specimens of the 
Miocene Foraminifer named by him Burseolina calabra. Owing to their fossilised 
condition, the septation of the shells is more or less obscure, and in this respect their 
structure is not quite correctly rendered by the drawings that accompany his description 
of the species ( loc . cit.). A comparison with recent specimens leaves no doubt that the 
Tertiary form is identical in all important characters with the globular variety of 
Cassidulina represented in PI. CXIII. fig. 8. 
Yon Hantken has described an oval, somewhat compressed Cassidulina, from the 
Hungarian Tertiaries, under the name Cassidulina globosa (Mittheil. Jalirb. d. k. ung. 
geol. Anstalt, vol. iv. p. 64, pi. xvi. fig. 2, a.b.), but this appears to be an intermediate 
variety, scarcely separable from Cassidulina crassa. The specimens figured by Egger 
with the name Cassidulina globulosa (Xeues Jalirb. fur Min., &c., 1857, p. 296, pi. xi. 
figs. 4-7), are evidently Globigerince, and probably belong to more than one species. 
In the living state Cassidulina calabra has only been met with at two points, 
namely: — off Paine Island, Torres Strait, 155 fathoms ; and off Kandavu, Fiji Islands, 
610 fathoms. 
Seguenza’s fossil specimens were from the Upper Miocene of Reggio, Calabria. 
Cassidulina bradyi, Norman (PI. LIY. figs. 6-10). 
Cassidulina bradyi (Norman, MS.) Wright, 1880, Proc. Belfast Nat. Field Club. — App., p. 152. 
„ ,, Brady, 1881, Quart. Journ. Micr. Sci., vol. xxi., N. S., p. 59. 
Test spiral, compressed; oval, reniform, or crosier-shaped; lateral faces convex, 
peripheral edge thin, sharp or slightly rounded. Early segments planospiral, embracing, 
arranged on the normal Cassiduline plan ; later segments oblique, alternating, forming a 
straight or curved biserial line. Aperture loop-shaped, situated on the inner face of the 
terminal chamber. Length, ^-th inch (0'42 mm.). 
This species was discovered many years ago by the Rev. A. M. Norman, and in the 
absence of any published description has been referred to by subsequent authors under 
his manuscript name. 
Morphologically, Cassidulina bradyi bears somewhat the same relation to the typical 
Cassididina laevigata, that Cristellaria crepidulct or Cristellaria obtusata bears 
to Cristellaria rotulata ; in others words, the later portion of the test exhibits a 
tendency to form a straight or curved line instead of continuing the spiral mode of 
growth. In localities where the species is plentiful, the specimens show a great variety 
of contour, some, like fig. 10, being not much longer proportionately than Cassididina
