			{{Ref-Kunitomo1920}}

			Embryo No. {{CE221}} has 38 somites and a remnant, the latter showing constrictions at three points. The caudal end of the embryo resembles that of a pig, as described by Keibel in his work on the human embryo. The cloaca, which is situated at a level with the thirty-first somite, is well developed, but as yet there has been no perforation of the membrane. Below the chorda dorsalis is a short remnant of the caudal gut containing a small lumen, as can be seen in figure 4, plate 1. At their caudal extremities the chorda, spinal cord, and caudal gut appear to fuse together. The central canal of the spinal cord is obhterated at its sacral portion, showing a pathological condition, and appears as a solid mass of nervous tissue. The groove between the tail-bud and the cloaca, which in the younger specimens indicated the first jroint of disappearance of the caudal gut, is here situated at the level of the thirty-first somite and is destined to later develop into the subcaudal epithelial plate. In this embryo there are 31 spinal ganglia with nerves.
