The gross structural peculiarities of nasal meatuses were studied in mithun and zebu. The dorsal nasal meatus was found to be narrow and longest in mithun, while it was reduced in length in zebu. The middle nasal meatus was smallest and bifurcated at the level of the 1st cheek tooth and communicated with the frontal sinuses. The ventral meatus was narrow and longest, which communicated with the frontal and sphenoidal sinuses in both the species. Tha common nasal meatus was longer and roomy ventrally in mithun, while it was relatively more elongated in zebu.
