part. Towards the sides they are more numerous, 4 mm. apart. 

 At the margin they are still closer, 3 mm. or less apart, and on 

 the lower side of the tip of the tongue they are separated by inter- 

 spaces not even measuring 2 mm. Auteriorly, the diameter of the 

 papillae fungiforms is 1 mm. or not quite that, but they increase 

 in size posteriorly, so that the diameter of those in the groove 

 measures 1| mm.

The posterior thick portion of the tongue is covered by large, 

 horny, scale-like papillas. They are 2 (24) mm. broad in the 

 median region, but their size diminishes towards the sides, where 

 they measure only about 1 mm. These are homologous with the 

 small papillae on the anterior portion of the tongue, but are 

 rounded instead of poiuted. The lateral surface of the posterior 

 portion of the tongue is beset with minute and conical jhi/iH/,! 

 fUiformes. Laterally, and on the posterior two-thirds of the central 

 region of the hind tongue, rather large papillae fungiformes are
