shape, it began from oropharyngeal cavity and terminated on the proventriculus. The esophagus was
divided into two regions are represented by cervical part and Thoracic part, the crop was absent.
Internal lining of the esophagus consisted of un- branched straight longitudinal folds the mean length
of esophagus was about 25 cm; it was wider in the anterior part than the posterior part.
