BOMBINATOR. 143 



Head depressed, as long as broad, or slightly broader 

 than long; snout rounded, scarcely projecting, as long 

 as the diameter of the orbit ; no canthus rostralis ; no 

 loreal groove ; nostril a little nearer the eye than the 

 tip of the snout ; eye rather small, very prominent, 

 directed upwards and outwards ; interorbital space 

 narrower than the upper eyelid and nearly equal to 

 the distance between the nostrils. 



Fingers short, obtuse, first shortest, third longest, 

 fourth a little longer than second ; no subarticular 

 tubercles ; two or three round palmar tubercles, inner 

 usually largest and more prominent. 



Hind limb stout, little longer than head and body ; 

 the tibio-tarsal articulation reaches the axil or the 

 shoulder, the tarso-metatarsal the commissure of the 

 jaws or the eye ; tibia a little shorter than the femur, 

 the heels not meeting: when the leo;s are folded at 

 right angles to the rhachis. Foot longer than the 

 tibia ; toes short, obtuse, flattened, at least two-thirds 

 webbed in the adult, sometimes nearly entirely webbed, 

 but the membrane always with deep crescentic emargi- 

 nation ; in young specimens the toes may be barely half 

 webbed ; no subarticular tubercles ; a very small and 

 feebly prominent round inner metatarsal tubercle. 



Upper parts covered with more or less prominent, 

 round or oval, distinctly porous warts ; each may be 

 tipped with closely set black asperities, none of which, 

 as a rule, are developed into true spines, although 

 there is sometimes a conical central eminence. Some 

 of the warts may run together and form short chains, 

 particularly an oblique, posteriorly converging pair 

 between the shoulders, and a parotoid-like one on 

 each side behind the eyes; a distinct fold usually 

 extends below the latter, from the eye to the base of 

 the arm. Lower parts smooth, or with small scattered 

 granules, each of which is tipped with black horny 

 matter as on the dorsal warts ; lower surface of thio-hs 

 with laro-er flat granules ; a more or less strono- o-ular 

 fold separating the head from the body.
