The figures in the classical work of Plancus on which Linne based the present species 
are hold and characteristic. They indicate straight, tapering, Nodosarian shells, with 
four globular segments apiece and a central orifice on a somewhat produced neck, the 
surface of the shells being smooth and devoid of ornament. The chambers are more 
inflated and the sutures more depressed than those of the specimens from which the 
illustrations, PI. LXI. figs. 28-31, are drawn, the latter showing some approach to the 
characters of Nodosaria humilis, Roemer (Verstein. norddeutsch. Kreid., 1841, pt. 2, 
p, 95, pi. xv. fig. 6). In these particulars many of the figures referred to in the 
synonymy accord much better with the original type. 
Nodosaria radicida has a wide area of distribution. It is found in the arctic seas, 
and on the shores of Norway and of the British Islands ; in the North Atlantic, from shallow 
water to a depth of 1360 fathoms ; in the South Atlantic as deep as 2350 fathoms ; and 
in the South Pacific from 37 to 1100 fathoms ; and it also occurs in the Adriatic. It has 
not been observed in the North Pacific. 
In the fossil state, the species has been identified in the Permian formations of 
England and Germany (Brady), in the Upper Trias of Derbyshire (Jones-and Parker), in 
the Lias of various parts of England (Brady, Blake) in the Kimmeridge Clay (Blake), in 
the Chalk of the North of Ireland (Wright), and at almost every stage of the Tertiary 
series.
