A Study of the Crania of the Moriori 
differ in upper face height in exactly the opposite direction. Thus in the 27 
measurements compared in the case of the male crania, our differences in four, 
the capacity, the transverse arc, the frontal section of sagittal arc and the orbital 
breadth (involving a fifth, the orbital index) are, I believe, due to differences in 
the methods of measurement. In the case of the female measurements the com- 
parison is not so satisfactory ; not only are my numbers small, but Scott's are still 
smaller. This fact, however, would not account for his absolute lengths being 
almost invariably smaller than mine. As I have said I think he may have laid too 
great stress on mere smallness of the skull in sexing. Notwithstanding the combined 
measurements, transverse arc, orbital breadth and orbital index excepted, give 
even in the case of the female crania by no means unsatisfactory results. Unless 
— which seems now very improbable — further long series of Moriori crania are 
found. Table II, combining Scott's results with my new measurements, must stand 
as the best available system of Moriori cranial data. It involves measurements 
of nearly 100 skulls of a race now practically extinct, and should be helpful in 
determining the racial affinities of the Moriori. 
Before leaving Scott's important paper, I should like to note some of the 
peculiarities of the Moriori crania emphasised by him. He states that typical 
Moriori crania are usually large and heavy ; our table of comparative measure- 
ments (Table III) amply verifies this statement as to size. As to the weights 
we find : 
Mean Weight of Crania. 
Moriori Fuegian Egyptian 
(Thomson) (Sergi and Martin) (Davin) 
Males 764-3 grs. 872-3 grs. 623-6 grs. 
Females 622-2 grs. 722-5 grs. 482-4 grs. 
It is possible that the Fuegian crania were weighed, unlike ours, with mandible 
attached. If so this would account for some, if not all the difference observed. 
Clearly the Fuegians have very heavy crania, and the Moriori heavy crania, 
but the latter are not absolutely unique in this respect. The average weight of 
an Egyptian mandible is 73-1 grs., but of course in the case of these crania the 
material is in a very different state to the Moriori crania. Still I do not think 
that the observed difference, 108 in males and 100 in females, can be wholly due to 
mandibles being included in Sergi and Martin's weighings of Fuegian and not 
included in our weighings of Moriori. I am inclined to think that while the Moriori 
crania are heavy, they are not as heavy as the Fuegian. The contours also bring 
out the same point of great size. 
Scott further draws attention to the prominent parietal eminences, the roof-like 
vertices and the pentagonal character of the norma occipitalis. Our Plates XIV, 
XV, IV, and VI will amply demonstrate to the reader these Moriori features. 
Further he remarks on the low flattened retreating frontal region as a most 
striking feature (cf. our Plates III, VII and XV). This character is well measured
