The present study was carried out on the third to fifteenth coccygeal vertebrae of six specimens of adult Blue bull (Boselaphus tragocamelus) of either sex. The Cy3-Cy6 presented complete arches and spinous processes. The transverse processes and cranial non-articular processes were present in Cy3-Cy6 and then reduced in caudal part of the series. The transverse processes were found to be plate like that were directed downward, backward and exceeded beyond the level of the posterior articular surface of the body in Cy3. They were reduced to tubercles in were reduced to tubercles in Cy4-Cy7 and disappeared beyond Cy7. The neural rings were found to be complete in Cy3-Cy4 and then became reduced in Blue bull. The dorsal supraspinous processes were found to be thin and flat in Cy3-Cy4. The summits of the dorsal supraspinous processes were thick, tuberous and bifid. A foramen having 0.09±0.001 cm diameter was located 0.64±0.012 cm away from the dorsal spine in Cy3 in the Blue bull. The cranial processes were present in Cy3-Cy5 and they disappeared after Cy5. The caudal processes were absent. The extremities of bodies were rounded anteriorly and flattened posteriorly. The ventral spine was prominent up to Cy7 and thereafter persisted as the ventral tubercle. The fifteenth coccygeal vertebra was represented by cylindrical body with reduced processes. The Biometrical observations on different parameters of third to fifteenth coccygeal vertebrae reflected significance (P<0.05) differences between the sexes of this species.
