The 3 Kerala tribes show Veddid ethnic affinity both from the point of view of the blood groups and anthropometric measurements. They show much ethnic affinity with the southernmost inhibitants of the Australoids of India. The Pulaiya and the Paraban show striking similarity with the Paniyans (Aiyappan, 1936). The Todas are Europid while the Kotas and the Chenchus are Veddids. Target cell anemia is present in both South Indian and North Eastern India Tripal people, but an abnormal Hb pattern is absent in South India, while the incidence of Hb. E in North Eastern India, 19.7%, is noteworthy. It may be mentioned here that in a randomization study of the West Bengal population in Calcutta by us, so far the abnormal Hb. E pattern has been detected in 1.2% of the population only, with or without target cells in the blood. It is well known that the number of carriers of Hb. E trait is substantial, well over 10% in some of the neighboring Eastern countries, Burma, N. Malaya, Indochina, Siam and others.
