Tyrannus verticalis 5 19 April 2 1/2 mi N. Patterson, Stanislaus C., Calif. left along dorsal body wall joins large intestine. Thread at end. Large Intestine; Caeca, which make the beginning of the large gut, come off where the final loop is fullest toward left body wall. LI continues looping toward center line, where it joins cloaca. Caeca: Extend on ventral lateral surface of smallint., forward (anteriorly) bond by conn. tissue to it. Left cacum 3 mm. Right caecum 3 mm. Wider than in other birds, and more pouch-like than tubular. Measurements: Ducts: A duct from right lobe of liver extends between folds of duodenum, enters duodenum on ascending loop, a little close halfway, at level of ant. end of ventral pancreas. A duct from ventral pancreas extends from its posterior end and enters duodenum just before (proximally, posterior) the bile duct. Ducts may be destroyed when gut is removed. Measurements: Dissected around cloaca, tore away all mesenteric, extended without stretching, the entire gut, for measurement. Duodenum: - 38 mm. Small Int.- 102 mm. Large Int. - 16 mm. Duct + ST = 140 mm.
