Remarhs. “ This species most nearly resembles Nautilus ohesus^ 
J. Sowerby, but it may be readily distinguished by its less robust 
shell, wider septa, and less open umbilicus, as well as by the slightly 
different position of the siphimcle. 
“ The Trench specimen is a natural cast showing the sutures, 
siphuncle, and internal lobe, but the ornamentation of the inner 
whorl or young shell only is preserved. This consists of very fine 
lines of growth, crossed by fine, longitudinal, thread-like lines, the 
decussating sculpture characteristic of the young of Nautilus. 
“ It is very doubtful whether the English references to this species 
are correct, because d’Orbigny’s figure in the ‘ Paleontologie Eran- 
gaise ’ does not correctly represent this species, a- specimen of which 
from the d’Orbigny Collection we have had the opportunity of 
examining.” {Foord and G. C. Crick.)
