DR. C. F. SONNTAG ON THE ANATOMY 



Genus Leontocebus. 

 The Lion Marmoset [L. rosalia). 



The two specimens examined were preserved, so no measure- 

 ments were taken. 



The tongue rapidly tapers from base to apex ; and the latter is 

 pointed and covered with a dense cluster of small fungiform 

 papillae. The middle of the dorsum is occupied by a strip of 

 mucosa covered by closely-aggregated conical papillfe. 



The Circumvallate Papilke (text-fig. 51 B, b). — Three papillae 

 form an isosceles triangle with two short sides and a long base. 



Text-tiaure 51. 



Tlie inferior surfaces of the tongue and vallate papillffi of some Marmosets. 



The apical papilla is a short distance anterior to the epiglottis, 

 and the basal papillae are close to the edges of the tougue. 



All the papillae are large and nodulated, the fossae are well- 

 marked, and the Valiums are clear zones or lobulated bands. 



The Fungiform Papillce, which are prominent, form a well- 

 marked dorsal bounding zone on which they have the usual 

 arrangement in clusters and rows, and they increase in size in the 

 usual manner. Two rows of small elements connect the basal 

 vallate jiapillte. None are present on the posterior pai't of the 

 ventral papillaiy zone. 



All are prominent, hemispherical, and smooth. 



17ie Conical Papilke (text-fig. 51 B, c). — No apical cluster is 

 present, for the transverse rows extend right forward to the apex.
