【Abstract】 With cross anatomical method,the anatomy of the skull bones of reindeer was studied and compared with that of camel,horse and cattle.The results were as follows:The vomer of reindeer is very developed.A group of ethmoidal cellules were formed among the lacrimal bone,frontal bone and nasal bone.The mandible is longer and narrower than that of cattle,horse and camel.The angle of mandible is obtuse.The lacrimal bone has a pair of lacrimal foramen which lie on the cranral part of orbital margin and separated by the lacrimal process.The reindeer has no lacrimal saccus fossa.On the ventral part of the orbital margin,the zygomatic bone formed a deep notch of the orbital margin.更多还原
