118 HON. W. ROTHSCHILD ON THE GENUS CASUARIUS. 
128: 89 mm. It is, however, not ascertained that it is an egg of C. c. beccarii, which, 
as we know, is not the only Cassowary living in the Aru group. That the eggs of any 
Cassowary are more transparent than those of any other species is evidently not the case.

Adult. Casque dull brown, very high and much compressed laterally, very thin, and 
when fully adult curved over to one side. Bill long and stout, black. Wattles very 
large and long, sometimes over 7 inches, but in the old birds they get torn and 
damaged either in fighting or when creeping through the thick scrub, so that often 
they are very short or split into a number of ragged ribbon-like appendages. This is 
well illustrated in the series of figures of D’Albertis’s fine specimens in Count Salva- 
dori’s monograph. This is the largest form of the C. caswarius group and also the 
largest Cassowary, standing, when erect, as much as 6 feet high and the body being 
fully half as big again as that of an Emu (Dromeus). Plumage black, head and 
occiput pale whitish blue. Fore-neck and nape brilliant indigo-blue. Hind-neck of 
a most intense bright scarlet. Naked lower sides of the neck, posterior 2 brilliant 
scarlet, anterior 4 bright blue. Total length about 1600 mm., bill from gape 130 to 
140 and even 145 mm., tarsus 280 to 300 mm., inner claw 80 to 95 mm. 
Juv. (two-thirds grown). Plumage dark brown, often nearly as black as adult, also 
occasionally pale yellowish brown. Fore-neck leaden blue; head and occiput pale 
blue. Hind-neck dull orange-yellow. Naked lower sides of neck, anterior 4 blue, 
posterior % yellow. 
Chick. Head and neck dark rufous, variegated with black bands and spots. 
Longitudinal dorsal bands very broad, about 13 inches wide, black, slightly variegated 
with rufous, and 5 in number—z. e., a central one and two lateral pairs ; one band on 
flank extending down the thigh on each side, and a second one indicated by a number 
of dark brown irregular spots. 
Hab, Southern New Guinea from Port Moresby to the Princess Marianne Strait, 
and perhaps even up to McCluer’s Inlet. 
I have had several examples of this bird alive, though none quite adult. They
