lp⁴, the intestine extends straight caudad, parallel and near to the straight region leading from the posterior intestinal portal, until it reaches the region of the loop lp², dorsal to which it forms a small loop, lp⁵. From loop lp⁵ the intestine, which is here of very small caliber, extends caudad for about 10 mm., where it forms another indistinctly double loop, lp⁶.

From loop lp⁶ the large intestine, il, extends, with gradually increasing caliber, to the cloaca, cl, a distance of 10 to 15 mm.

Except in the enlarged region near the pylorus the lumen of the intestine is almost obliterated by the folding of its thick walls, so that little or nothing can be told of its lining with the naked eye.

A distinct mesentery holds the loops of the intestine in position and binds the entire enteron close to the dorsal body wall. Because of the lack of properly fixed tissue no sections of the enteron of this stage were made.
