520 DR. C, F. SONNTAQ ON THE ANATOMY 



Manis. In the species in which I observed them they have the 

 usual arrangement in an npical chister, and in rows of varying 

 degrees of obliquity behind that. They are also present on the 

 lateral borders, but they are restricted to a narrow bounding 

 zone on the inferior surface of the tongue. They stretch back 

 to the neighbourhood of the epiglottis, but those on the base of 

 the tongue are not very large. In Orycteropus (text-fig. 52) the 

 individual papillfe are easily distinguished ; in the Bradypodidse 

 they can only be detected through a lens ; and in the Dasypodidte 

 they vary in prominence to such a degree that the dorsum, 

 appears granular {Dasypus) or almost shaggy (Tatusia). Some ot 

 the types of conical papillre in the Dasypodidse and Brady podidse 

 are shown in text-fig. 53. 



Oppel (17) described scanty conical papillae in Manis, and 

 Tuckerman (21) stated that those in Dasypus villosus are inter- 

 mediate in character between the coronate and fasciculate 

 papillte in Marsupials and the mechanical papillae in higher 

 Mammalia. Secondary papillae are found on many of the 



main ones.

Glands:— Op])e\. (17) and Podwisotzky (19) mapped out the 

 serous and mucous glands of the tongue in Manis javanica. 

 They showed that the mucous glands form a cluster on the base 

 of the tongue, whilst the patch of serous glands lies far forwards 

 round the vallate papillae. Owing to the large size of the 

 salivary glands the mucous glands are not very numerous. I did 

 not observe any patulous glandular orifices in the Myrmeco- 

 phagidte or Orycteropodidre. In the specimen of Manis at my 

 disposid the base of the tongue was concealed to a considerable 

 extent by the sheath. But in Bradypus I observed a number of 

 orifices and lymphoid nodules. No apical gland of Nuhn is 

 present. 



The serous glands vary in the Dasypodidae ; they are numerous 

 in Dasyptis vUlosus, but scanty in D. peha. 



Lytta : — The only Edentates which possess a lytta are Manis 

 gigas and M. javanica. It has been described and figured by 

 bppel (17) and Rapp (20) ; and Mayer (14) poicts out that it is
