Molar i is intermediate in character RHYNCHIPPUS EQUINUS 97 between the premolars and the succeeding molars, beingonly slightly rhomboidal in outline, while in the last twomolars the anterior external corner is markedly different individuals, the lower jaw varies greatly inheight, but this seems to me to be individual and sex varia-tion.
