Two new Frogs from Madagascar. 421 



than broad, flat above, sides nearly vertical ; snout as long 

 as the diameter of the orbit, with sharp canthns and feebly- 

 grooved lores ; nostril midway between the eye and the tip 

 of the snout; interorbital space nearly as broad as the upper 

 eyelid ; tympanum very distinct, three fourths the diameter 

 of the eye. First finger considerably shorter tlian second ; 

 toes webbed to the disks, with small subarticular tubercles ; 

 inner metatarsal tubercle small, oval, scarcely prominent, 

 measuring- about one fourth the length of the inner toe ; disks 

 of fingers and toes small but well developed. The tibio- 

 tarsal articulation reaches the eye or between the eye and. 

 the nostril. Skin finely shagreened above, with scattered 

 very small warts ; smooth beneath ; femoral glands present, 

 not punctured (?). Dark grey-brown above, with whitish 

 dots and indistinct darker blotches ; a fine light vertebral 

 line ; limbs with indistinct dark bars ; hinder side of thighs

 white ; throat mottled with greyish brown.

Bhaco-pliorus Peraccce. 



Vomerine teeth in two slightly oblique oval groups just 

 behind the level of the choange. Head as long as broad ; 

 snout rounded, not projecting, as long as the diameter of the 

 orbit ; canthus rostralis obtuse ; loreal region concave ; nostril 

 midway between the eye and the end of the snout; inter- 

 orbital space as broad as the upper eyelid ; tympanum distinct, 

 half the diameter of the eye. Fingers with rudimentary web, 

 first much shorter than second ; disks large, as large as the 

 tympanum. Toes half-webbed, with smaller disks and small 

 subarticular tubercles ; two small metatarsal tubercles, inner
