THE VOYAGE OF H.M.S. CH ALLEN GEE . 
■Nodosaria perversa, Schwager (PL LXIV. figs. 25-27). 
Nodosaria perversa, Schwager, 1866, Novara-Exped., geol. Theil, vol. ii. p. 212, pi. v. fig. 29. 
„ pupoides, Silvestri, 1872, Nodos. Foss, e Viv. d’ltal., p. 65, pi. iv. figs. 148-158. 
An imperfectly striate form, nearly related to Nodosaria scalaris. It is well figured 
both by Schwager and Silvestri, and the living specimens, especially that represented in 
fig. 25, closely resemble the drawings furnished by these authors. 
In the living condition Nodosaria perversa has only been obtained off the Ki Islands, 
south-west of Papua, depth 129 fathoms. 
The fossil specimens above referred to were from beds of later Tertiary age in the 
Nicobar Islands, Italy, and Sicily. 
Nodosaria ( D .) subcanaliculata, Neugeboren [var.J (PI. LXIV. figs. 23, 24). 
Dentalina subcanaliculata, Neugeboren, 1856, Denksehr. d. k. Akad. Wiss. Wien, vol. xii. p. 87, 
pi. iv. figs. 5, 6. 
Under the name Dentalina subcanaliculata, Neugeboren has figured two slender, 
curved, Nodosarian shells, which are characterised by their numerous segments, straight 
sutures, and a peculiar surface-ornament consisting of short, broken, longitudinal 
striae. The specimen represented in PL LXIV. figs. 23, 24, exhibits the same kind 
of external marking ; and as the test is manifestly abnormal in point of form, it may be 
treated provisionally, in the absence of other indications of its affinity, as an aberrant 
modification of the species referred to. 
The recent shell was obtained from a sounding off Tahiti, 420 fathoms. 
The original type-specimens were fossils from the Miocene of Transylvania.
