little hollows in Dasypus peha ; and those lying on the posterior 

 part of the tongue have well-developed taste-buds. No papillae 

 fungiformes are present on the lateral borders. 



Lateral Organs : — There appears to be considerable variation 

 in the lateral organs, for the views of various authors are 

 conflicting. I observed no trace of organs in Mi/rmecophaga 

 jiibata, Tamandua tetradactyla, Cyclothurus didactylus, Manis 

 (ap. ?), Orycteropus capensis, Jiradypus tridactylus, Tatusia (sp. ?) 

 and Dasyp>us villosus. Mayer (14) observed them in Myrmeco- 

 phaga and the Dasypodidse. Boulart (1) and Tuckerman (21)

found them in Tatusia, and the latter author found them taking 

 the form of minute openings in several Armadillos ; taste-buds 

 and serous glands were connected to them. Gmelin (9) found 

 no trace of organs in Orycteropios, the Armadillos and Sloths, and 

 Podwisotzky (19) saw them in Dasypus sexcinctus. So it is 

 evident that the organs are variable in the Dasypodidse, but 

 usually absent in the other Edentates. 



Conical Fapillce: — These papillse are well-marked in the 

 Bradypodidre, Dasypodidco and Orycteropus, but I found no trace 

 of them on naked-eye examination in the Myrmecophagidse or
