THE VOYAGE OF H.M.8. CHALLENGER. 
Nodosaria radicula, var. annulata, Terquem and Berthelin, var. (PL LXII. figs. 1, 2). 
Glandulina ■annulata, Terquem and Berfchelin, 1875, Mem. Soc. geol. France, ser. 2, vol. x. m6m. 
III. p. 22, pi. i. fig. 25. 
This variety only differs from the typical Nodosaria radicula in the decreasing size 
of one or two of the later segments, the test being widest near the middle instead of at 
the oral end. 
Terquem and Berthelin figure two closely allied Nodosarians with the same 
peculiarity, under the names Glandulina anmdata and Dentalina mciuritii respectively 
(loc. cit., figs. 25 and 28); the recent specimens present intermediate characters connecting 
the two. D’Orbigny gives us the same variety, but with a somewhat crescentiform aperture, 
in his Lingulina rotundata (For. Foss. Vien, p. 61, pi. ii. figs. 48-51). 
The best living examples that have been met with are from Station 192, off the Ki 
Islands, 129 fathoms. 
Nodosaria radicula , var. ambigua, Neugeboren (PL LXII. fig. 3, a.b.). 
Nodosaria ambigua, Neugeboren, 1856, Denkschr, d. k. Ak. Wiss. Wien, vol. xii. p. 71, pi. i. 
figs. 13-16. 
,, tornata, Schwager, 1866, Novara-Exped., geol. Theil, vol. ii. p. 223, pi. v. fig. 51. 
This is a sub-varietal modification of Nodosaria radicula , with abnormally short 
segments. 
Habitat, off the Ki Islands, 129 fathoms. 
It occurs amongst other Nodosaria} as a Tertiary fossil. 
Nodosaria simplex, Silvestri (Pl. LXII. figs. 4, 5, and fig. 6 ?). 
Nodosaria simplex, Silvestri, 1872, Nodos. Foss, e Viv. d’ltal., p. 95, pl. xi. figs. 268-272. 
Of the three drawings, fig. 4 corresponds in every particular with Silvestri’s illustrations 
of Nodosaria simplex (loc. cit.), and fig. 5 resembles the same in a less degree ; whilst fig. 6 
bears more similarity to those of Nodosaria antennulci (of Costa, not of d’Orbigny) 
furnished by the same author ; but what may be the zoological value of either “ species,’ 
the Challenger specimens are insufficient to show. 
The recent examples are from — off the Ki Islands, 129 fathoms, and off the west coast 
of New Zealand, 275 fathoms. 
Those figured by Silvestri and Costa were from the Subapennine Tertiaries of 
Italy.
