of the same species, were found in material dredged in 
210 fathoms off Kandavu, one of the Fiji Islands. 
Their structure is of much simpler type than that of 
the gigantic discs dredged by Sir E. Belcher on the 
coast of Borneo, which formed the basis of Dr. Carpen- 
ter’s description of the genus. The better specimen is 
a thin dise about +, inch (1°5 mm.) in diameter, some- 
what biconvex; the convexity is chiefly in a limited 
area near the centre of the test, the remainder being 
thin, and tapering to a sharp edge at the periphery. 
The texture is distinctly hyaline. 
This little shell appears to represent the “ central 
chambered plane” of the large forms, without the 
thickened shelly plates on the upper and lower surface. 
The chambers form a single layer, disposed in tolerably 
regular annuli; in shape they are nearly square, not 
elongate in the direction of the radii as in the larger 
species, and the septal lines are slightly raised 
externally. 
I would suggest, for the sake of distinction, that the large 
type, which, I believe, has never received a specific name, 
should be called Cycloclypeus Carpenteri; that now des- 
cribed I propose to name after Professor Giimbel, of Munich, 
who has worked with so much success on the allied genus 
Orbitoides. 
3. Note on “ Biloculina-mud.” 
In the second paper of this series,! some remarks were 
offered upon the Foraminifera collected at or near the 
surface of the ocean by means of the tow-net. A list was 
given of the free-swimming species, so far as they were 
known, and the question whether all the varieties of Godt. 
gerina and the three or four pelagic species of Pulvinulina, 
live exclusively at the surface of the open sea, was dis- 
cussed. The recorded facts bearing upon the subject were 
summarised, as well as the results of my own observatiuns, 
not with the view of announcing any conclusions in the 
matter, but chiefly in the hope of eliciting further contribu- 
tions to the knowledge of a subject, concerning which there 
was still much to be learnt. The question, from a zoolo- 
gical stand-point, is now a comparatively narrow one. It is 
not whether Foraminifera do live at the bottom of the sea,
