NAUTILOIDEA. 
Remarlcs. In general form this species resembles N. suUceviyatiuf, 
d’Orb.,but is distinguished from it by the two spiral bands, by which 
it is easily recognized. 
This seems to be a rare species, as only one specimen was known 
to its author. 
A crushed example (No. 42906) from the Upper Cretaceous of 
Nagorzany, near Lemberg, in Galicia, may be referred to this 
species, its inflated form, small umbilicus, and the character of its 
septa agreeing perfectly with Favre's type. It is also from the 
same locality as the latter. 
Horizon. Upper Cretaceous. 
Localities. Westphalia (No. 74040) ; Nagorzany, near Lemberg, 
Galicia (No. 4290G). 
Fairly well represented in the Collection.

Sp. Char. Shell inflated, rapidly expanding, especially in the 
region of the aperture, where, owing to the deep peripheral emar- 
gination and lateral expansion of the shell, the latter Jias a bilobate 
appearance, suggesting that of some species of Bellerophon. The 
umbilicus is very small. The septa are moderately distant and 
almost straight. The siphuncle is nearly central. The test in the 
adult shell is marked with suhregular lines of growth, which are 
strongly emarginate in the median line of the periphery ; in the 
young the lines of growth are so distinct as to assume the appearance 
of fine ribs^.
