13 Prot. 
PROTOZOA. 
spherical ; formed of concentric layers, each consisting of a large num- 
ber of chamberlets, arranged more or less regularly in single series. 
Chamberlets of the same layer, communicating with each other by short 
lateral stolons ; those of the successive layers by the pores which formed 
the superficial apertures of tho previous layer. Aperture consisting of 
numerous pores, one at the margin of each chamberlet. Colour white ; 
surface areolated by the outlines of the somewhat convex chamberlets 
of the peripheral layer. Examples of the single species, K. murrayi , were 
dredged by the ‘ Challenger’ from a depth of 1950 fathoms, 25 degrees 
south of the south-western corner of Australia. The external appearance 
is that of a globular variety of Tinoporus , while the arrangement of the 
chamberlets most nearly approaches that of Orbilolites. 
Duncan, P. M. On the genus StoliczJcaria , Duncan, and its distinctness 
from Parlceria , Carp. & Brady. Op. cit. ix. pp. 58 & 59. 
StoliczJcaria granulala , g. &sp. nn., is referred to the author’s family of 
the Syringosphceridce , including with Syringosphceria , Duncan (“ Scientific 
Results of tho Yarkand Mission,” 1879, p. 10), a group of fossil llhizo- 
poda established by him for the reception of the sphseroidal organisms 
known in India as Karakoram stones. In StoliczJcaria , as compared with 
Syringosphceria and Parlceria , to which it also bears a considerable resem- 
blance, the surface is covered by numerous granulations, separated by 
intervals about equal to their breadth. There are no pores on the 
surface ; but tube-openings occur in the granulations. The central ones, 
which are small, are the terminations of the very numerous radial series, 
which, in section, are not very conical, but nearly straight, and give off 
minute offshoots to the surrounding convoluted and varicose larger tubes 
of the inter-radial series, which open towards the periphery of the granu- 
lations. There is no coenenehyma. 
Maupas, E. Sur le LieberJcuJxnia , Rhizopode d’eau douce multinucMe*. 
C. R. xcv. pp. 191-194. 
The multinucleate structure of this Rhizopod is maintained, in connec- 
tion with examples obtained from pond-water at Hamma, near Algiers. 
Another important histiological point established, is that the so-called 
chitinous shell, or test, is not an independent skeletal structure like that 
of Arcella and Difflugia , but simply a somewhat hardened integument or 
ectosarc, which it is possible to isolate under the action of certain reagents. 
In the living animal, it adapts itself to every protean change of the body 
contour, and takes part in tho fissive process of subdivision. 
Heilprin, A. On the Occurrence of Nummulitic Deposits in Florida, 
and the Association of Nummulites with a Fresh- water Fauna. 
P. Ac. Philad. 1882, pp. 189-193. 
Nummulites wilcoxi , a new species, figured and described, was obtained 
by Mr. Joseph Willcox, from the western shore of the peninsula of Florida, 
where it occurs in such quantities as to constitute a true Nummulitic rock. 
The rock is a white or yellowish-white friable limestone, found in the 
immediate neighbourhood of the Chushowiska River, Hernaudo County, 
four miles from the coast. The bed whence the fragments were obtained
