[75] The fourth, or _teres major_, border is present also, of course,

in all instances of type 5, and in most specimens of type 4. It is

particularly common in the Peruvian scapulæ.

_Superior border._—The form of the superior border of the scapula can

be divided for purposes of description into (1) horizontal or slightly

rising and forming a right or nearly right angle with a vertical line

passing upward from the base of the coracoid; (2) moderately rising or

oblique and straight or but slightly curved, forming with the coracoid

vertical an angle of between 85 and 55°; (3) markedly oblique, forming

with the coracoid vertical an angle of less than 55°; (4) angular or

deep saddle-shaped, which is of special importance anthropologically;

and (5) markedly concave or semilunar (see pl. 25). In rare instances

a form (6) occurs, in which the border is low and moderately convex,

and another (7) in which it is markedly concavo-convex; and, finally,

there occurs now and then an indeterminate form (I), which can not be

classified.

[76] Type 1=horizontal or but slightly inclined; 2=moderate to medium

obliquity; 3=pronounced obliquity; 4=deep saddle-shaped; 5=semilunar;

6=convex; 7=markedly concavo-convex.

[77] In two specimens (2 per cent) the form of the border was

unclassifiable.

The data obtained in this particular on the Munsee and other Indian

groups, as well as on a large series of whites, are given in the

next table. It is very evident that racial and tribal differences of

some importance exist in the shape of the border. Among the whites

its most common form is type 2, or moderate to medium oblique,

pronounced obliquity being infrequent; types 4 and 5 occur but rarely.

In the Munsee there is a curious but doubtless local prevalence of

the semilunar type 5, the next most frequent form being that of

pronounced obliquity; and one-fourth of the cases show the saddle

form or an approach to it. Among other Indians the conditions differ.

The cliff-dwellers of southern Utah come, on the whole, near to the

whites; among the Mexican Indians low borders prevail, while among the

Northwest Coast tribes we find the opposite condition—high borders,

with a relative frequency of the angular or saddle-shaped type (4 or

near 4). It is an interesting fact that the last named form (4) is

frequent and often highly developed in the Eskimo.

The question occurs as to how the form of the superior border differs

in the two sexes and on the two sides, and the next table throws some

light on these problems. It will be observed that among the Indians the

differences between the males and the females are not striking, though

there is a tendency toward greater obliquity of the border in the

males. Among the whites, types 1 and 4 are more common in the females

than in the males; type 2 occurs about the same number of times in the

two sexes, while types 3 and 5 are more frequent in the males.

As to the two sides, we find that a slightly lesser tendency to marked

obliquity of the border exists in the left than in the right scapula;

while the bone of the right side shows greater frequency of the angular

or deep saddle-shaped (type 4 or near 4).

_Scapular notch._—The notch in the scapular border, at the base of the

coracoid, which, as is well known, transmits the suprascapular nerve,

may be absent, shallow, medium deep, or converted into a complete

foramen. Among the 21 scapulæ of the Munsee and 431 of whites, the

conditions in this respect, with reference to sex and side, are as

follows:
