spine (ns), the base of which is less than half the length of the neural arch; on each 
side the spine, at some distance from it, there is a vacuity (0) in the neural platform. 
This vertebra, from the analogy of the cervical region in the skeleton of Dinornis and 
Casuarius, has come from the anterior part of the neck, and was probably the third or 
fourth of the series. 
A cervical vertebra (Pl. LXIV. figs. 5 & 6), from the lower or hinder third of the 
neck, shows a heemal canal (/) beneath the fore part of the centrum (fig. 1, c’), formed 
by the parapophyses (p, p); the hypapophysis has disappeared from the back part of 
the centrum (c’). The thick and short pleurapophysis (p/) shows three longitudinal, 
shallow, wide grooves; the diapophysis (d) forms a thick, obtuse, sub-bifid projection, 
external to and below the prezygopopkysis (2), from the back part of which extends a 
slender bar of bone (0) to the side of the centrum, unequally dividing the hinder outlet 
of the vertebrarterial canal (v). The interzygapophysial plates are here wanting, as is 
also the neural spine, its place being occupied by a chevron-shaped, rough tuberosity (¢), 
as in the vertebrze of the bend of the neck, which is concave neural. 
In a cervical vertebra, contiguous or near to the preceding, the posterior aperture of 
the vertebrarterial canal (v) is more equally divided by a horizontal bar of bone. 
Other cervicals do not present characters worthy of special notice. 
Dorsal Vertebre. 
The bodies of the dorsal vertebre (Pl. LXIV. figs. 3 & 4) have the usual terminal 
concavo-convex articulations, the concavity being transverse on the anterior surface (c’) ; 
the last is compressed, the sides converging below to a ridge, representing a hypapo- 
physis. The neural spine (zs) is 1 inch 6 lines in height, 10 lines in fore-and-aft 
diameter, moderately thick, with a truncate, subexpanded, transversely convex summit ; 
the diapophyses (d) are strong, trihedral, being supported by a trihedral buttress 
(fig. 4,4). Inthe antecedent dorsals, of which seven are preserved—probably the entire 
number—the lower part of the centrum is produced into a compressed hypapophysis 
(fig. 3, hy); the articular surface for the head of the rib is an oval depression, near the 
front margin of the centrum, supported upon a slightly produced parapophysis (p) ; 
the terminal subconcave surface on the diapophysis (d), by its distance from the para- 
pophysis, gives the length of the neck of the rib, and enables one to identify, as belong- 
ing to Cnemiornis, some of the ribs in the promiscuous lot of bones raised out of the 
fissure at Timaru. 
Pelvis. 
The pelvis (Pl. LXIV. figs. 5, 6,7) includes seventeen sacral vertebrz with the coalesced 
ossa innominata ; from which, however, the pubic and ischial bones have been broken 
off. The bodies of the sacral vertebrze diminish in breadth to the third (fig. 6, c), where 
the sides converge to a ridged inferior termination ; they then expand to the seventh,
