The biangular form, which is fairly frequent in whites, is nearly 
absent in the Munsee, the one pair in the males presenting merely an 
approach to the form. 
SPINE 
The entire number of vertebra of 21 skeletons has been preserved, 
thus affording an excellent opportunity for studying the numerical 
relations of the bones, as well as other particulars. 
The bones are entirely normal, with the exception of the frequent 
slightly to moderately developed marginal exostoses (which, unless 
premature or excessive, the author regards more and more as the 
usual manifestations of age rather than of disease), and one case of 
advanced spondylitis deformans, resulting in fusion of the lower half 
of the spine and the sacrum. The bones show moderate to medium 
development and are free from gross anomalies. 
As to numbers, the cervical vertebre show but one exception to the 
Gunton eamn cle in male skeleton no. 285,326, in which only six 
vertebre are present in this region. The locus of the (congenitally) 
missing one is between the third and the sixth, its exact identity being 
difficult to determine. In one of the females (no. 285,311) the 
seventh cervical, as already mentioned, gives attachment on the right 
to a well developed cervical rib (pl. 25, a). 
The vertebre of the dorsal region are also normal in number in all 
cases but one, which has been mentioned in connection with the ribs; 
it is no. 285,321, female, and presents a congenital absence of the 
twelfth vertebra. 
The numbers of the lumbar vertebree show frequent variation. In 
two of the ten males and two of the eleven females there are but four 
lumbars, while in one female there are six. In detail we find the 
following abnormalities: 
In male skeleton no. 285,316, the fifth lumbar shows a transitional, 
sacral form, though not attached to the sacrum, and it also presents 
a detachment of the posterior part of its neural arch. 
In male no. 285,326, one of the lumbar vertebrae between the second 
and fifth is absent cunecnrinltys 
In female no. 285,310, one of the lumbar vertebre is missing con- 
genitally; the last lumbar in this case is in form like the fifth; the 
upper segment of the sacrum is somewhat lumbar-like, but the bone 
possesses only five segments and a normal curvature. 
In female no. 285,311, with four lumbar vertebra, the fifth, some- 
what modified, is Sitached to the sacrum (pl. 27). 
In female no. 285,326, where we have six lumbar vertebra, the- last, 
like the lowest ints in male no. 285,316, shows a separation of the 
posterior portion of the neural arch. 
In male no. 285,308, the twelfth dorsal and the first lumbar show 
complete and evidently early non-pathological fusion.
