Pupil horizontal. Tongue free and deeply notched behind t. 

 Vomerine teeth. Tympanum distinct or hidden. Fingers free ; toes 

 webbed, with simple or dilated tips. Outer metatarsals separated 

 by web. Omosteruum and sternum with a strong bony style. 

 Terminal phalanges acute, transversely dilated or T-shaped. 



Cosmopohtan, except the southern j)arts of South America and 

 New Zealand ; one species from the extreme north of Australia. 



The study of the numerous species included here in liana shows 

 the impossibility of dividing them into genera, or even subgenera, 

 according to the dilatation or non-dilatation of the tips of the fingers 

 and toes. The extreme forms, viz. Bana hexculactyJa and It. afyhccna, 

 show indeed a very marked difference respecting the shape and struc- 

 ture of the fingers and toes — the former having them pointed ; the 

 latter dilated into very large disks supported by regularly T-shaped 

 phalanges. But, when we meet with such forms as B. malaharica, 

 B. curtipes, B. inguinalis, &c., we must hesitate before referring 

 them to the " Platydactyla " or to the " Oxydactyla," and, in fact,
