Pre-Colombian Jamaica: Caribbean Archeology and Ethnohistory

240 / Appendix D.
The average upper facial index of 9 specimens is 50.8, or just within the leptoprosopic
group, (min. 46.2, max. 55.7).
The naso- malar index of 19 crania averages 107.6, or just mesopic, (min.
104.7, max. 111.3). Only one is prosopic, the remainder are fairly evenly divided
between mesopy and platyopy.
The average orbital index is 92.5, or very megaseme; only six orbits, out of
about forty, were mesoseme, (min. 85.4, max. 100—three orbits).
The nasal index is irregular, the average of 20 crania is 51.2 (min. 40.5, max.
69.2). The numbers are fairly equally divided between lepto-, meso-, and platyrhiny.
The average palatal index of 10 crania is 119.5 (min. 101.7, max. 131.3,
two specimens). With two exceptions, all the examples are well within the
brachy uranic group.
The average cranium may be described as microcephalic, brachycephalic,
metriocephalic, mesognathous, leptoprosop (barely), mesopic (barely), megaseme,
mesorhine, brachyuranic.
As an example of the variation that occurs, the following is the analysis of
these crania (G, O, and P) which belong to the collection kindly loaned by the
Rev. W. W. Rumsey:
G. Megacephalic (1470), brachycephalic (84.7), metriocephalic (75.1), mesognathous
(98.9), leptoprosopic (52.6), mesopic (109.2), megaseme (95 and
96.2), leptorhine (43.3), dolichuranic (101.7).
O. Microcephalic, brachycephalic (85.8), barely metriocephalic (72.1), mesognathous
(99.4), chamaeprosopic (49.2), barely mesopic (107.7), megaseme
(91.1 and 90.5), platyrhine (61.4), brachyuranic (125.5).
P. Microcephalic (estimated), brachycephalic (90.2), platyopic (106.9), mesoseme
(88.3 and 87.5), platyrhine (56.1).
The first of these is artificially deformed to a very much less extent than the
two latter. In the detailed paper the effect of artificial deformation will be more
fully discussed, not only as it modifies the head form, but also its apparent action
on the bones of the face.
I would like to take this opportunity of thanking the Board of Governors of
the Institute of Jamaica for entrusting this valuable collection to me for description,
and for the patience with which they have waited for the report.

Pottery
From the various caves have been obtained the best and most perfect representatives
of the ceramic art of the Jamaican aborigine. Although quantities are
known from the kitchen- middens, it is all in a fragmentary condition. The ex-
