Lachrymal synonyms

The lachrymal occupies a considerable space on the flat surface of the cheek in front of the orbit, and below it the jugal does the same.

The lachrymal forj amen is always within the orbital margin; and in many species the infra-orbital foramen is very large (in some as large as the orbit) and transmits part of the masseter muscle.

In the skull the lachrymal bone is large, the paroccipital process is directed vertically downwards and the tympanic bulla is hollow.
