122 HON. W. ROTHSCHILD ON THE GENUS CASUARIUS. 
Young (full-grown). Plumage black, mixed with brown feathers. Head and neck 
deep blue, paler around the ear ; lower hind-neck scarlet. Naked lower sides of neck 
very bright blue. 
Hab. unknown. 
In addition to the type I have had five others alive, and they all agreed in having 
the intense blue colour and the entirely blue naked lower sides of the neck; but this 
Cassowary remains still a very little-known form, and will do so till its habitat is 
discovered. The original description is as follows :-— 
« 3 ad. The casque differs from that of C. caswarius in being very high and much 
more erect; the wattles almost entirely blue instead of dark red ; the blue of the head 
and neck uniform and very dark; the orange of the hind-neck much restricted and 
separated at the upper end from the blue by a black crescent-shaped patch ; naked 
sides of lower neck entirely uniform blue instead of red, bordered anteriorly with 
blue.”

6. CASUARIUS CASUARIUS VIOLICOLLIS Rothsch. Violet-necked Cassowary. (Plate XX VI.) 
1899. Casuarius casuarius violicollis Rothsch., Bull. B. O. C. vii. (nos. lix., xiv.) pp. xxv, lv. 
Adult. Casque low, sloping back very much, laterally compressed, horny brown, 
green at base. Bill very long, straight and pointed. Plumage black. Face bluish 
green. Occiput and upper hind-neck pale greenish blue, throat and fore-neck brilliant 
deep blue. Hind-neck orange-scarlet. Naked lower sides of neck bright violaceous 
mauve, bordered anteriorly with a narrow line of blue, posteriorly with a narrow line 
of scarlet. Two wattles on fore-neck large, round, and close together in female ; small, 
long, and wide apart in male, blue at base, rest fleshy pink. 
Juv. (half-grown). Plumage brown; neck and head dull leaden blue; hind-neck 
dull gamboge-yellow; lower naked sides of neck dirty flesh-pink. 
Juv. (three-fourths grown). Plumage brown, with a few black feathers; head and 
occiput pale dull blue; fore-neck dull indigo; hind-neck orange; lower naked sides 
of neck dark pink streaked with purplish red. 
Hab. ? Trangan Island, Aru Islands. 
The type of the species was imported along with two specimens of C. bicarunculatus 
from Aru, and is a female, for she has laid an egg; but I have since received seven 
others of this form, and they all agree in their characters. As the other islands of the 
group are inhabited by different forms of Cassowaries, I am inclined to think that 
Trangan Island must be the home of this interesting form. 
I described this form at the January meeting of the British Ornithologists’ Club in 
1899 as follows :— 
“This apparently undescribed form of Cassowary is most nearly allied to Casuarius 
casuarius salvadorii, but differs conspicuously in the colour of the naked parts and in 
the very large size, which fully equals that of C. ¢. australis.
