lanibJoitI cresfc. Rostrum long and slender (as in MiyaJoi/lossKs), its 

 actual length (orbit to nares) varjing, according to species and 

 races, from a litlle loss to a little more than one-third of total 

 length of skull; front of orbit above same point of, or even 

 (il/. iiiinimits sobriims, often also M. m. wiiiu'mtes) distinctly behind, 

 nr. I'remiixillffi similar in form to those of £oni/cfeins and Mcgah- 

 (/^osso.s (ascending branches not broader above than below), but more 

 ])roclivous than in Mfijaloi/lossiis and much more so than in Eony- 

 deris (see fig. 71, below), and (as in Megalocjlossus) solidly united 

 anteriorly. Infraorbital canal less shortened than in Eonycteris 

 and Aleyaloijlositus, its anterior aperture (infraorbital foramen) at 

 k'ast a little, and in the longer-muzzled forms (e.g. M.iit. sobrinus) 

 much, in front of anterior point of orbit, its outer wall con- 

 spicuously broader (antero-posteriorly) than height of zygoma at

middle. Postorbital foramina present. Foramen ovale and 



rotundum close together or (in some individuals, irrespective of 



species and race) confluent. Tympanies unmodified. Tempoial 



ridges low down on sides of cranium, a sagitral crest therefore 



never developed ; mandible very similar to that of 3Iega]ogJussiis, 



but symphysis relatively longer, as a rule between one-fifth and 



iiiie-fourth (in Meydloylosmts about one-sixth) of length of mandible 



from condyle; symphysis keel (on anterior inferior surface of 



symphysis) generally strongly developed (obsolescent or absent in 



the eastern races of M. lai/orhilun).
