PLATE XXXVIII. 
Casuarius lorie. Loria’s Cassowary (p. 142). (Drawn from a sketch made from

PLATE XXXI1X. 
Casuarius bennetti. Bennett's Cassowary (p. 145). (Drawn from life from a bird 
formerly at Tring, now in the Zoological Society’s Gardens.) 
PLATE XL. 
Map showing the geographical distribution of the six subspecies of Casuarius 
casuarius and of Casuarius bicarunculatus. 
PLATE XLI. 
Map showing the geographical distribution of the three subspecies of Casuwarius 
unappendiculatus, two of Casuarius papuanus, two of Casuarius picticollis, Casuarius 
lorie, and Casuarius bennetti. 
PLATE XLII. 
The dorsal aspect of the Skull (figs. 1-4). 
Fig. 1. The skull of Rhea americana (p. 270), to show the form of the temporal fossa, 
the partly fused mesethmoid plate, the form of the lachrymals and nasals, 
and the broad nasal process of the premaxilla. 
Fig. 2. The skull of Dromeus nove-hollandie (p. 270), showing the rod-like nasal 
process of the premaxilla, the fused lachrymal, broad interorbital region, and 
widely separated! temporal fosse. 
Fig. 3. The skull of Struthio molybdophanes (p. 269), showing the supra-orbital ossicles 
running backwards from the lachrymal to the frontal, and the broad nasal 
process of the premaxilla. The mesethmoidal suture is obliterated. 
Fig. 4. The skull of Apteryx australis (p. 269), showing the small size of the lachrymal 
and the absence of its supra-orbital processes, the complete fusion of the 
nasal process of the premaxilla, and the rounded form of the frontals, which 
do not protect the orbit above. 
Ventral aspects (figs. 5-8) 
Fig. 5. The ventral aspect of fig. 1, showing the large size of the palatine 
processes of the premaxilla and of the maxillo-palatine processes. The 
peculiar relations between the vomer, palatine, and pterygoid (described on 
p- 207), and the anterior end of the parasphenoidal rostrum between the 
anterior cleft of the vomer.
