THE CAT. 



[CHAP. in. 



From the inner side of the pre-maxilla the slender second or 

 palatine process (p) extends backwards, in contiguity with its fellow 

 of the opposite side, till it meets the anterior margin of the palatine 



plate of the maxilla. A 

 notch is thus formed be- 

 tween this backwardly ex- 

 tending process and the

more external portion of 

 the pre-maxilla, and this 

 notch is converted into a 

 foramen by the palatine 

 plate of the maxilla behind 

 it. This is the anterior pala- 

 tine, or incisor foramen, which is the anterior termination of the 

 anterior palatine canal transmitting the naso-palatine nerve. 



33. The MALAR is a rather small, lamellar bone which forms the 



most prominent part of the cheek, 

 the outer inferior margin of the orbit, 

 and the anterior part of the zygoma. 

 It is in the form of a curved 

 quadrangular plate, convex without, 

 concave within, and with certain 

 processes. Its anterior inferior 

 margin (m) rests on the malar pro- 

 cess of the maxilla. Its anterior 

 superior margin forms part of the 

 rim of the orbit. Its posterior 

 portion, or zygomatic process (2) is 

 applied beneath the lower border 

 of the zygomatic process of the 

 squamosal. Immediately in front 

 of the anterior end of that process 

 the malar developes a post-orbital 

 process (p) which mounts upwards, 

 backwards, and inwards, towards 

 but not to, the post- orbital process 

 of the frontal. The postero-inferior 

 margin of the malar is strongly concave. 



33. The NASALS are two elongated, small triangular bones 

 placed side by side above the anterior nares in front of the frontals. 

 Each is considerably extended vertically towards its hinder end 

 (B and C), and somewhat less extended transversely towards its 

 distal end (A). Its anterior margin is concave, its external angle (a) 

 being produced forwards much beyond its internal angle. 



The inner side of the vertically- expanded part of the bone (B) is 

 flat, and applied to its fellow of the opposite side. Its outer surface (C) 

 is concave, and receives the nasal process of the frontal in a fossa 

 specially destined for it (n). The nasals join the frontals, maxillae, 

 and pre-maxilla) ; and form the superior margin of the anterior nares.
