Described in detail by Brewer[1][2]. “There is no branching of a mesodermal villus.” Chorion, 3.6 x 3 x 1.9 mm. Chorionic cavity, 1.85 x 1.71 x 1.01 mm; capacity, 13.38 mm3. Embryonic disc, 0.209 x 0.177 mm; volume, 0.0814 mm3. Primitive streak, 0.04 mm, claimed, but its presence was denied by Krafka (1941)[3]. No allantoic diverticulum. Dorsal and median projections published (Brewer, 1938[2], plate 1, figs. 2 and 3; Mazanec, 1959[4], fig. 33). Some authors have attempted to identify a prechordal plate from the median projection.
