moidal meatuses (Hauptfurchen) are present. He also finds a 

 corresponding number of ethmoidal conchae (Hauptmuscheln), 

 but includes among the number, as his "erste Hauptmuschel," 

 the agger nasi (nasoturbinal) plus the processus uncinatus. Kil-

Fig. 18 (X 10) Outline drawing of a frontal section through the nose of the 

 same embryo as that in fig. 17. The plane of section in this figure (slide 40) is 

 farther dorsal, and is in the region of the bullar folds. 



The processus uncinatus projects free at this plane of section, and the infun- 

 dibulum ethmoidale communicates rather freely with the meatus nasi medius. 

 The cartilage of the processus uncinatus is not continuous with the cartilage of 

 the lateral plate at this level — compare this with the cartilage of the processus 

 uncinatus in fig. 17.
