Of 4450 Murrah buffaloes, 17 (0.4 %) exhibited a total of 229 warts on their skins. Higher prevalence was recorrded in male buffaloes. The nunber of lesions in individual animals varied from 1 to 78 with a mean of 13.3 +- 20.9 SD. The diameter of the lesions ranged from 0.2 - 2.0 cm with an average of 0.5 +- 0.2 SD. The average affected area of the skin was 3.0 +- 4.2 DS with a range of 0.2 - 16.6 sq.cm. The lesions were observed on 13 different sites with a higher frequency on the shoulder, chest, and neck.

Short term lymphocyte culture technique was used to study the chromosomes of normal and abnormal buffaloes of some breeds of Indian river buffaloes. The diploid number in Murrah, Surti and Jaffrabadi breeds was found to be 50. Chromosome abnormalities such as trisomy-X, pericentric inversion and C-band deletion in animals with reproductive deficiencies besides chimaerism (50, XX/50, XY) in heterosexual multiple births, and secondary constrictions in some apparently normal animals are described

Occurrence of two different types of symmetrical conjoined twin monsters described as syncephalus tetrapus tetrabrachius and dicephalus dipus tetrabrachius among riverine buffaloes of India is reported.
