306 DR. C. F. SONNTAG ON THE ANATOMY 



bent with the angles directed forwards. The right organ is 

 1 cm. long, and has 8 laminae and 9 sulci. The left organ is 

 1*1 cm. long, and has 9 laminae and 10 sulci. At the anterior 

 extremities are fungiform papillae (a) and false folds (&), the true 

 laminae and sulci being shown at c. The organs are fiat on 

 elevation (C). 



The Pig-tailed Macaque (M. nemestrinus). 

 Habitat : East Indies and Malay States. 



Measurements. — Total length 8 - 4 cm. ; length of the oral part 

 7*3 cm. ; length of the pharyngeal part l'l cm.; width between 

 the lingual attachments of the palato-glossal folds 2*7 cm. 



The apex and lateral borders are the same as in M. rhesus, and 

 the same structures are absent.

A. 



The vallate papillae (A) and lateral organs (B) of Maeacus nemestrinus. 



The Circumvallate Papillae (text-fig. 29 A). 

 Seven papillae are arranged in the V-type. All are very pro- 

 minent, the fossae are clearly defined, and the Valiums form well- 

 marked zones. In this formation my specimen resembles that of 

 Munch (8), but differs from Mayer's example (7) in which there 

 were four vallate papillae. The vallate area contains both conical 

 and fungiform papillae. In my second specimen the apical papilla 

 is replaced by three papillae deeply sunk within the common 

 fossa. It is unusual to have the three papillae of a cluster deeply 

 recessed ; they are usually prominent. 



The Fungiform Papillae (text-fig. 31 A). 

 The distribution is the same as in ill. rhesus, but they are not 

 so numerous in the centre of the oral part of the dorsum. They 

 are very numerous behind the apex and in front of the vallate 

 area. The ventral apical cluster is also large, but the posterior 

 part of the ventral papillary zone has few papillae. 



The Conicad Pacpillae (text-fig. 31 B). 



The arrangement of the papillae .and inclination of their points 

 take the usual form. 



The papillary bodies are flat, conical or cylindrical, and the 

 number of points is variable. 



A few minute orifices of glamal ducts mid pits are present.-
