Gaultieri’s figure, selected by Linne as the type of Nautilus obliquus, represents a 
somewhat bent and tapering Nodosarian shell, with slightly depressed sutures, and 
ornamented externally with numerous, moderately fine, longitudinal costae — very 
similar, in fact, to the specfinens portrayed in PI. LXIV., but of somewhat stouter 
contour. 
The above synonymy embraces only a few of the names which have been given to 
forms which lie well within the limits of the quasi-specific group typified by the 
original figure, and no attempt has been made to render the list complete. * 
Costate Nodosarians referrible to this species are found in every sea, and at almost 
every depth from the laminarian zone down to 1500 or 2000 fathoms. 
In the fossil state they occur as far back as the Lower Lias, if not earlier, and 
thenceforward in marine beds of nearly every geological age. 
Nodosaria vertebralis, Batsch, sp. (PI. LXIII. fig. 35 ; PL LXIV. figs. 11-14). 
Nautilus ( Orthoceras ) vertebralis, Batscii, 1791, Conchyl. des Seesandes, p. 3, No. 6, pi. ii. fig. 6,

Nodosaria fascia, Parker, Jones, and Brady, 1865, Ann. and Mag. Nat. Hist., ser. 3, vol. xv, 
p. 227, No. VI. 
The shell of Nodosaria vertebralis is long, slender, slightly tapering, and generally 
more or less curved ; the segments are very numerous and the septal lines straight ; and 
the surface is marked by distinct, continuous, longitudinal striae or riblets. The outline 
is even and the sutures are unconstricted ; the septa are conspicuously thick and 
formed of transparent shell-substance, but not limbate externally. 
Batsch J s figures are drawn from a broken specimen, but as usual they give an accurate 
idea of its characteristic points. They have been assigned to Nodosaria fascia , Linn., sp., 
but Gaultieri’s figure, on which that species is based, indicates a relatively broad stout 
shell, with raised or limbate sutures.
