348 Anomalies of Pigmentation among Natives of Nyasaland 
deficient pigmentation. The affected areas were the right side of the upper 
part of the face, two small patches on the same side of the neck and a patchy 
condition of the fingers. (See Plate XIII, Fig 5.) 
The area on the face was sharply limited along the mid-line of the nose and 
forehead. The two patches on the neck were at the anterior margin of the 
trapezius muscle over the mid-point of the clavicle. The mottled condition of 
the fingers rather resembled that seen in Ziemann's leucoderma. 
The general skin colour was that of cake chocolate. The affected areas 
were the colour of bruised chocolate. In addition to the affection of the skin, 
a segment of the iris about one-sixth of the total iris in extent, with the base 
directed towai'ds the right side, was of a light hazel colour, the remaining five- 
sixths being a dark brown, the same as the iris of the other side. The hairs of the 
scalp, eyebrows and eyelashes were normally black. The condition was noticed 
at birth, according to the mother's statement, and had not altered. The mother, 
father and brother of the subject were all normal, and no members of the family 
were known to have presented any pigmentary anomaly. 
I., female, aged 5 (1909). Seen at Kondowe ; she presented congenital 
anomalies of pigmentation in that there was absence of full colouration of the 
skin ; the back of the right hand, with the inner three fingers, the palm, and 
the back of the right arm, the abdomen, groin, thigh and leg of the same side 
were the seat of patchy deficiencies of colour, with spots quite white or pinkish 
white to various shades of brown, resembling somewhat the condition seen in 
leprosy, or the non-leprous leucodermic affection of the skin of the hands 
described by Ziemann. The condition was stated to be congenital and not to 
have altered. No other members of the family were affected. 
Daus, of Chimwai village, Dwangwa River, male, aged 11 years (1909). An 
area of skin on the cheek, as indicated in Fig. 6, Plate XIII, is of pinkish white 
colour resembling that of an albino ; the area is smooth and on the same plane 
as the surrounding dark skin. The demarcation is abrupt, with no increase in 
pigmentation of the skin in the neighbourhood. Over the albinotic patch and 
also more abundantly on the surrounding skin are distributed fine white short 
curved hairs, no other hair being present on the cheeks. A few white hairs are 
seen on the same side of the upper lip, and the middle portion of the eyelashes 
on the upper lid of the same side are white. 
There is an area of skin just in front of the tragus of a lighter hue than the 
rest of the skin of the face, which is a rather dark brown black colour. Irides 
dark brown. History states that these anomalies of pigmentation were present 
at birth. They have enlarged with growth, but there has been no relative increase 
in size. No other members of the family known to be albinotic. 
The girl " H." presents a condition of extraordinary interest. In the first 
place, I can put on record a case of congenital incomplete spotling albinism, that
