The lumen is still narrowand slit-like, so that the circular, ring-like appearance of the cri-coid is not yet established. The sides seem compressed more orless one upon the other. The artaenoid masses, (fig. 4), make their appearance at thistime, and although rather intimateh related to the cricoid mass,nevertheless permit of recognition. They are roughly of ovalshape and bear little resemblance to their adult are of course composed purely of precartilage; they developmore slowly than do the cricoid or thyreoid, but keep abreastof the epiglottis in their growth. Even at the 20 mm. stage whenthe cricoid and thyreoid show a predominance of chondrificati^n,the arytae
