THE KEILOR FOSSIL SKULL: PALATE AND UPPER 
DENTAL ARCH. 
By William Adam, D.D.Se. 
Plates X-XI. 
Standard anatomical terms are used in describing the palate 
and teeth; the methods adopted for measurements are those of 
the Galton Laboratory, London University. The points between 
which measurements were made are those defined by Buxton and 
Morant (3) ; in addition, other measurements suggested by Camp- 
bell (4) are included. Standard anthropometric instruments and 
modifications of standard precision instruments were used. Data 
concerning recent Australian aborigines are quoted from Campbell 
(4) and those for recent Tasmanian aborigines are from an 
unpublished thesis submitted by the author of this paper for the 
Degree of D.D.Sc., in which his researches on jaws and teeth of 
56 ‘Tasmanian skulls are recorded; a typescript copy of this thesis 
has been deposited in the Melbourne University Library. 
Although measurements are recorded to one-tenth of a milli- 
metre, it is not claimed that this degree of accuracy is attained in 
every instance owing to the difficulty of precisely locating the 
position of certain points since the alveolar margins have been 
slightly abraded post-mortem. 
The mandible is missing. 
The upper jaw is large, well developed and somewhat projecting. 
The infra-orbital (canine) fossa is large and deep. The right 
maxilla is slightly larger than the left. 
The following measurements give figures for the Keilor skull, 
modern Tasmanians and modern Australians. G’TH is the Nasion- 
Alveolar Point chord; LB, the Nasion-Basion chord; and GL, the 
Basion-Alveolar chord. LB and GL for the Keilor skull were 
measured by Dr. J. Wunderly. The Tasmanian group includes 
both males and females; the figures in brackets are maximum and 
minimum measurements. 
The Australian group (males) is Morant’s pooled A group, first 
sample (Morant, 6, p. 487); the figures in brackets indicate the 
number of specimens measured :
