 These regions occur in reversed positions in right- and left-handed 

 collars, and vary in form according to the simple or elaborate charac- 

 ter of the ornamentation. 



b. Boss. — The so-called boss is a rounded, generally unpolished, 

 prominence or swelling, well marked in slender but absent in massive 

 collars, being generally undecorated. and so situated that it separates 

 the two panels. In massive forms the boss is continent with the 

 undecorated panel, but in the slender it is evidently a continuation 

 of the decorated panel. 



p. Projection. — The projection, which is a significant feature of 

 the collar, lias the form of a slight swelling or a rounded elevation, 

 closely appressed to the body of the collar, to which it appears to be 

 bound by an encircling shoulder ridge or fillet. In massive collars 

 there are generally two protuberances, which may be called projec- 

 tions, one on each side of the ridge; but in slender collars there is 

 only one, which emerges from under the shoulder fillet on the side 

 opposite the boss. Sometimes the projection is ferruled, often with 

 pits like exes, and in one collar the prominence is said to have 

 the form of a snake's head.' 



sb. Shoulder ridge. — The shoulder ridge is a raised band, cut in 

 low relief, partly encircling the collar near the base of the projection, 

 which it appears to bind to the body of the collar. It is sometimes 

 broad and tlat, but more commonly is a narrow bead, and in massive 

 forms where there are two projections it fills the interval between 

 them. Rarely absent, it is seldom in very high relief. 



dp. Decorated panel. — This term is applied to that region 

 oi" the collar which lies adjacent to the boss, and on the side 

 opposite the projection. Although the name is a useful one for dis- 

 tinguishing ibis part in many specimens, this panel, although gener- 

 ally smooth, is not ornamented. The general outline of the decorated 

 panel of oblique ovate collars is quadrate or trapezoidal, with or with- 

 out a marginal panel ridge formed by a shallow groove. In the 

 massive forms the outline of this panel is often triangular. The 

 superficial decoration of the panels of massive collars, when present. 

 is less elaborate than that of the slender ones, and consists mainly 

 of pits, incised circles, triangles, or parallel lines. Figures of faces

 senl to me a drawing which shows the knob in the form of a snake's head.
