Sp. Char. Shell moderately inflated, compressed on the sides, 
rather broadly rounded on the periphery ; umbilicus open, small ; 
septa rather distant, sutures slightly flexuous on the sides, but pass- 
ing over the periphery without any perceptible sinuosity. Siphuncle 
situated nearly in the centre of the septa. Test smooth. 
Remarks. The specimen which I have referred to this species, 
with some measure of doubt, is a cast of three chambers of a rather 
large specimen. It is much distorted, so that it appears wider than 
it would otherwise be. It measures 3 inches in its greatest dia- 
meter by about 3| inches wide ; but the width is considerably in- 
creased by the vertical pressure that the specimen has undergone. 
Horizon. Miocene. 
Locality. Malta. 
Represented by a single example (No. C. 3363), which was pre- 
sented by John Murray, Esq., LL.D., Pli.D. 
Nautilus Geelongensis, Foord. 
Sp. Char. A number of detached casts of the chambers which, 
when fitted together, make up a shell of a somewhat inflated form, 
rather compressed on the sides, and broadly rounded upon the peri- 
phery. The aperture would be considerably wider than high. The 
septa are moderately distant, the sutures very slightly flexuous, 
with a dorsal lobe in the young shell (fig. 69, c). The siphuncle is 
nenrly central, perhaps a little below the centre. Not a vestige of 
the shell remains. 
Remarlcs. This species resembles Nautilus regalis, J. Sow., in its 
somewhat laterally compressed whorls and the position of the 
siphuncle ; but it is a more inflated shell than Sowerby’s, and its 
sutures much less flexuous. 
I can find no account of any Nautilus (properly so called) in the
