separated from each other, the wearer could both see and breathe 
through these openings. 
The smaller mask was not capable of being closely adapted to 
the face of a wearer, for the sphenoid and ethmoid bones were in 
position, and the orbits were filled up with a composition similar 
to that employed in modelling the face; and an artificial eye 
formed of the operculum of the shell of a mollusk was fixed in 
each orbit. An artificial tongue formed of a piece of bright red 
cloth folded on a wooden framework partially projected through 
the open mouth. Whiskers and beard, which in the larger mask 
were modelled in the hard composition, were in the smaller mask 
formed of vegetable fibre, and from their mode of arrangement gave 
a pantaloon-like character to the face. This mask may have been 
used as an ornament, or as an object of worship. 
Warrior Island, from which the skull was procured, is an 
island off the south coast of Hew Guinea, and to the north of Torres 
Straits. The skull was smeared on the forehead and face with 
streaks of red pigment. The orbits were filled up with a hardened 
material, to which lozenge-shaped pieces of mother-of-pearl to 
simulate eyes were attached. A plug of wood 3J inches long, cut so 
as to represent an artificial nose, was inserted into the anterior nares. 
The skull was that of an adult man, 175 mm. long, 154 broad, 
137 high, 515 in horizontal circumference, and with a capacity of 
1650 cubic centimetres. It was brachycephalic, megacephalic, 
mesorhine, and mesognathous. 
The skull was compared with the crania of Australians and 
Papuans, which are dolicocephalic, micro cephalic, and prognathous ; 
and it was pointed out that its affinities were not with these 
races but with the Malays. 
Various methods of decorating preserved heads and skulls were 
then referred to. This communication will appear in extenso in
