Variations which no doubt are due to sexual selections working 
within very confined limits, and under conditions peculiarly 
favourable to the creation of tribal peculiarities. This is I 
believe the cause of the many differences noticeable in travelling 
in New Guinea. 
The Motu tribe is remarkable for the uniformity of colour, 
and for the wonderful head of frizzly hair and aquiline noses of 
its members. 
The Koiari, living only afew miles from them, differ markedly 
in these characteristics. They have no immense mop of hair, 
but wear it wrapped up in a piece of tappa, have a flat obtusely 
pointed nose, and are either very dark skinned or as light as 
Malays. They are also shorter in stature than the Motu, 
although physically and morally immeasurably superior to them. 
Dr. Finsch mentions the curious fact that a light colored 
tribe is often sandwiched between very much darker tribes. I 
visited one of this description, that of Morocca, whose 
territory is situated on the watershed of the Laloki and St. 
George rivers under Mount O’Bree, 80 miles H.S.E. of Port 
Moresby. 
These people were remarkably hght in colour, approximating 
to the Malays, and in individual cases to Europeans. The form 
of nose prevalent among them gives them a decidedly Jewish 
appearance—yet I could not find any proof of crossing with 
other races. The neighbouring tribes were the Sogore 
and Ekiri on the north-west and north, and the Havéri and 
Favéri to the southward. These tribes were many shades 
darker than the Moroccans. Among the Sogore a few light 
colored individuals were noticeable, but even among all these 
tribes no two possess exactly the same shade of cclour, and many 
variations are noticeable in any given tribe. In some tribes 
the head is shorn as a sign of mourning, in others, the anterior 
portion of the skull is shaven by most of the men; in nearly
