Fm. sphplt., Foramen spheno-palatinum. — Sphenopalatine foramen. 

 Fm. infer.. Foramen infraorbitals. — Infraorbital foramen. 



§ 654. Lm. (Lamina) cribrosa — Cribriform plate of the ethmoid. — The mesethmoid 

 separates the bones of the two sides. The cribriform jjlate is the cranial part of the eth- 

 moid, the ethmo-turbinals properly belonging to the face. 



O. praesph., Os praesphenoideum, at. — 

 Prsesphenoid bone. 



O. pit., Os palatinum. — Palate bone.

O. Ich., Os lachrymale. — Lachrymal 



one (Fig. 56). 



O. planum (Fig. 56). 



O. ethtrb., Os ethmo-turbinale — Eth- 

 mo-turbinal bone. — In this figure is shown 

 the rounded scroll-like part projecting into 

 the frontal sinus (§ 550). 



O. frontis. — Frontal bone. 



Sinus frontalis. — Frontal sinus (Fig. 56). 



§ 555. Fig. 61— Preparation.— 

 After the removal of the soft parts 

 (§ 260, B), the rami were separated 

 at the symphysis 7nentl (Fig. 62). 



I 5j6. An. (Angulus) mandibularis. — 

 Mandibular angle. 



Cd. mndb., Condylus mandibularis. — 

 The condyle or arthral head of the mandible (Fig. 63). 



D. m., Dens molaris.' — Molar tooth. 



DD. pm., Dentes praemolares — Prsemolar teeth. — The bicuspides of Anthropotomy. 



D. c, Dens caninus. — Canine 

 tooth. 



DD. i., Dentes incisores. — 

 Incisor teeth. 



Fm. m , Foramen mentale — 

 Mental or labial foramen. — There 

 are almost invariably two on each 

 side in the cat. 



Fs. (Fossa) coronoidea— Cor- 

 onoid fossa. — From this fossa arises 

 a large part of the masseter muscle. 



Pre. cor., Processus coronoi- 

 deus. — Coronoid process. 



§ 557. Ramus, Ramus mandibularis — Mandibular ramus.^Tlie mandible is made 

 up of two similar bones joined at the symphysis menti, and these rami form the frame- 

 work of the floor of the mouth ; Flower, A, 120. 



In Human Anatomy, the " ramus " is the so called " ascending part," and not the 

 entire half of the mandible as here ; Quain, A, I, 54.
