papillae are more marked behind the spinous patch. The tongue 

 is not separated from the epiglottis by a smooth mucous ti^act. In 

 F. sylvestris, F. domestica, and F. caffra (text-fig. 20) the zone of 

 small conical papillse surrounding the spinous patch extends far 

 back along the lateral aspects of the dorsum ; it ha^ many fungi- 

 form papillae at the sides of the tongue, but few behind the apex. 

 The spinous patch begins a considerable distance behind the apex 

 of the tongue, and extends to the middle of the oral part of the 

 dorsum. The papillae spinosae are discrete, their points are 

 straight, and their granular bases are visible. Papillae clavatae 

 are well-marked. The conical papillae behind the spinous patch 

 are divisible, according to size, into a central and two lateral

tracts ; and the papillae on the pharyngeal part of the tongue are 

 large. In F. pardus (text-fig. 18), of which several varieties were 

 examined, the dorsal bounding zone of small conical papillae only 

 extends along the apex and anterior third of each lateral aspect 

 of the dorsum ; and it is well-studded with fungiform papillae ; it 

 is also very narrow when compared with the zone on other 

 tongues. The spinous patch begins close to the apex of the 

 tongue, but does not reach the middle of the oral part of the 

 dorsum. The papillae spinosae are discrete, and have sharp re- 

 curved points. No papillae clavatae are present. The conical 

 papillae behind the spinous patch are divisible into a central and 

 two lateral tracts ; and the papillae on the base of the tongue are
