Descriptions 



Gross morphology 



Both alcohol preserved specmiens or skins, were examined using a stereomicroscope. All 

 descriptions comprised also body size, characteristics of head morphology (nose leaf, 

 auricles, tragus, lower lip) and features of the pelage (colouring, areas of the body, hair 

 shaft) as well as the bones of the wmgs (metacarpalia, phalanges) and tail length. The 

 insertions of the plagiopatagium at the hind extremities and the shape of the uropatagium 

 are of special diagnostic value. 



Skull morphology 



Skulls were examined with a stereomicroscope using various magnifications (5x; 12.5x; 

 30x). For most overviews, five times magnification was sufficient, whereas features of the 

 dentition often required some higher magnification. If possible, the description considered 

 rostmm length compared to total skull length, the skull contours in lateral view as well as 

 the arrangement of the skull basis towards the level of the palate. Development of the 

 zygomatic arches was equally mentioned as were the features of the skull base: pterygoid 

 processes, convexity of pre- and basisphenoid („basisphenoid pits") and basioccipitale. 

 In all genera, the dentition was documented by dental formulas.The upper incisivi, canini, 

 premolars, molars, lower incisivi, lower canini, lower premolars and lower molars were 

 briefly described referring to specific peculiarities (contour of edges, height of crowns, 

 interdental distances, development of the masticatory surfaces, relative dimensions). 

 More detailed descriptions of the glossophagine dentition are given by Phillips (1971).
