DR. 0. F. SONNTAG ON THE ANATOMY 



that of F. hengcdensis. In F. caracal (text-fig. 20) tlie bounding 

 zone is wide. The spinous patch is small, and begins far from 

 the apex of the tongue. The conical pa.pillae behind the patch are 

 divisible, according to size, into a central and two lateral tracts. 

 Papillae clavatae are very well marked, and form a row of discrete, 

 prominent structures. The conical papillje on the base of the 

 tongue are pointed and discrete, being separated by wide areas of 

 the pharyngeal part of the dorsum. 



In CyiicBlarus jubatus (text-fig. 19) the bounding zone extends 

 half-way back along the dorsum, and it lodges a few small 

 fungiform papillae. The spinous patch begins far from the apex,

and does not i-each the middle of the dorsum ; and the points of 

 the papillae spinosae are slender and sharp. ISTo papillae clavatae 

 a.re present. The conical papillas behind the spinous i)atch are 

 divisible into a central and two lateral tracts, and tlie conical 

 papillae on the base are small. 



It is, therefore, evident that the tongues of the Felidae are 

 divisible into two groups, according to the presence or absence of 

 papillae clavatae. In the former are Felis domestica, F. sylvestris, 

 F. caffra, and F. caracal. As no examples of F. chaus and F. lynx 

 have come to hand the above list cannot be regarded as complete.
