Muzzle of the Javan Tailless Fruit Batis broad, swollen, ridged, hairless, very short, moderately deep, and etremely wide. Nostrils are tubular, with their bases and rims grossly swollen; philtrum is pronounced. Flap runs over lower lip from philtrum to passing middle length of lip, where it connects with vertical crescent ridge running from lip to back of nostrils, forming posterior margin of swollen lateral surface of muzzle. Pits occur on skin behind nostrils. Large pads occur on lower lip. Eyes are moderately large and bulging; iris is warm brown. Ears are moderately long, oval, and pale brown, with darker rim and small triangular antitragus lobe. Pelage is thin and moderately short, light gray suffused with brown on cap and faint yellow on shoulder. Hair is longer on nape and shoulders. Dorsal hairs have gray bases and long light brown tips, extending pass rump. Uropatagium is well developed along tibia and narrow in center, and calcar is small. Throat and chest are sparsely haired. Ventral pelage is gray and shorter than on dorsum. Dense woolly hairs extend to base of forearm. Wing membranes are grayish brown, thumb is long, and index claw is present, inserted on side of soft body and attached to first toe. Skull lacks basicranial deflection; rostrum is very short and moderately deep; nasals and premaxillae project forward as a short tube, but not exceeding canine; orbitis large but not surpassing dorsal profile of skull; braincase is rounded; anterior root of zygomais slightly above alveolar line; and zygoma is thin and gently arched,slightly bowed in dorsal view. Paranasal recesses are barely inflated, not reaching postorbital foramen; postorbital process is thin and projects posterolaterally. Palate is flat; post-dental extension is long, ends straight, and has no spine; and mesopterygoid fossa is flat. Ectotympanic is wide, and entotympanic is present along medial side of ectotympanic. Upper dentition has small and simple incisors, C' is small and slightly decurved, P' is a spicule, and posterior cheekteeth decrease in height. Lower dentition has small I, crowded between canines (I, absent), C, is small and little decurved, P, is peg-like, next premolar P,) is tall and simple, posterior teeth decrease in size, and M, is almost peg-like.
