The normal -adult form was first present in a specimen 14 mm. long (figs. 2 and 6). Fig. 9 is a reconstruction of a bifid apex in an embryo 11 mm. long, and fig. 12 is from a coronal section of a divided apex in an embryo 24 mm. long. When small hearts are dissected with the aid of the binocular microscope it is found that the two primary muscle bundles can be outlined in specimens 10 mm. long. At this
