406 THE ESKIMO ABOUT BERING STRAIT [ETH. ANN. 18 
area surrounding the eye is bordered by a narrow black line. The face 
on the back of the bird represents its inua. 
Figure 1, plate c, from lower Kuskokwim river, is 114 inches long by 
5 inches wide, and represents a human figure with outspread arms and 
legs. The head, arms, and legs are set in by squared pegs at their 
inner portion, which are inserted into holes in the body of the mask. 
The front of the body of this mask has a grotesque, semihuman face 
in low relief, shut in by little doors which, hinged upon either side, 
are made to open outward, and are controlled by sinew cords. This 
figure is similar in general character, except the doors, to a mask 
described from the lower Yukon (number 1445). The inside of the head * 
is deeply excavated and the back of the body is shallowly concave. 
Along the inside of the hands and arms, as well as of the legs to the 
feet, extend grooves painted red, bordered with black, and set with 
pegs to represent teeth. This indicates that the being represented was 
supposed to be provided with mouths all along these portions of its fig- 
ure. The head has two round eyes and a crescentic mouth with points 
upturned, but no features in relief. The face on the front of the body 
has the eyeholes, broadly spaced nostrils, and flattened oval, nearly 
horizontal mouth pierced through the mask; the mouth is provided 
with squared, peg-like projections to indicate teeth. The entire mask, 
when the doors are closed in front, with the exception of the mouth 
area along the arms and legs, is white. 
The inner surfaces of the doors, as well as the concealed face, are 
white with the exception of the outlined spectacle-like figure covering 
the eyes, a line indicating the mustache, and the figures of two rein- 
deer upon the inner side of one of the doors and the figures of two 
seals upon the inner side of the other door, which are black. <A nar- 
row strip of deerskin with upstanding hair surrounds the head. Upen 
each shoulder, as well as along the sides, are inserted white feathers. 
The exact meaning of this figure is not known, but the doors conceal- 
ing the face on the front of the body indicate that the concealed features 
are supposed to represent the inner countenance or inua of the being. 
Other masks of this character were seen in the region between Kusko- 
kwim and Yukon rivers, as well as on the lower Kuskokwim, and in one 
or more instances I saw masks having an outer or movable portion 
representing the muzzle of some animal which could be removed at a 
certain time in the festival by a single motion of the hand. These 
were used to represent the metamorphosis from the ordinary form of 
the being indicated to that of its inua. 
Figure 3, plate c, from Pastolik, at the northern border of the Yukon 
mouth, is a rather flat, pear-shape mask, 12? inches long by 54 inches 
broad. It is made with a grotesque, semihuman face on the rounded 
larger end and tapers back to an obtuse point at thetop. On the left side 
of the face are two rudely carved representations of human legs fastened 
to the mask by quills. One of these is inserted near the corner of the
