chopsis being a long groove (fig. C (6) extending distad to the 
middle of the side of the malleolus. 
Of these Jabiru-like birds, there seem to have been two species, 
a larger and a smaller. 
Xenorhynchopsis tibialis n.s. 
From this species we have two examples of the distal ends of 
tibias of opposite sides. That from the right leg, the one figured, 
is from a bird as nearly as possible equal in the size of the part 
to an ordinary Jabiru of to-day. The left tibia is from a rather 
large individual, but is rather more imperfect, and has no part 
of the shaft attached. Locality of both examples, Lower Cooper. 
^Xenorhynchopsis minor n.s, 
Tibia. — Distal end of a right tibia (Plate II., figs. 1 A, B). 
Since individuals of the present Jabiru do not vary very much 
in size, it would not, without reason to the contrary, be right 
to assume that an extinct bird of the kind did so. Necessar^y, 
then, a bone indicating an individual only two-thirds of the dimen- 
sions of Xenorhynchopsis tibialis must be taken to represent a second 
species. The malleoli of the Xenorynchopsis tibialis tibia measure 
at their widest extent 19.5 mm., those of the present bone 13 mm. 
The shaft of the latter shows an even greater difference, being 
but 7 mm. against 10 mm. in Xenorhynchopsis tibialis. A specific 
character still less open to doubt is the form and extent of the 
lateral groove (Fig. 1 Ba), which is relatively much shorter and 
more oblique. Locality, Unduwampa. 
Tarsometatarsus. — Imperfect trochleas of the right foot 
(fig. 1 C). This bone, which indubitably belongs to the Ciconiidce 
and does not belong to Antigo7ie, can only be referred on account 
of its size to Xenorhynchus nanus or Xenorhynchopsis minor. 
In the shatteied state of the fragments, it is impossible to place 
it in the latter genus with certainty, but the balance of probabil- 
ities seems to incline that way. Locality, Wurdulumankula. 
FAMILY I B I D I D iE. 
Ibis (?) conditus n.s. 
Femur. — A left femur injured in the head, neck, trochanter* 
and both trochleas (Plate II., fig. 2 A, B). — Notwithstanding the 
damages the bone has suffered it retains enough character to 
show that it formed part of one of the Ibididce, for to this family 
we are led by the absence of a pneumatic foramen, the presence of 
a moderately raised trochanter, and by its relatively stout pro- 
portions. In these it is assimilated to Carphibis spinicollis 
rather than to any other member of the family available for com- 
parison. It is slightly shorter than in a small example of that
