2 74 ANURA 



Jlantella. — Both omo- and raeta-sternum possess a bony style. 

 The tongue is free and distinctly mitred or cut out behind. 

 The skin is very granular. Several species, in Madagascar, 

 were formerly put into the same genus as the American forms, 

 uutil Boulenger established the genus Ifantella for them. The 

 coloration is strikingly pretty. M. madagascariensis is a rare 

 instance of difference in colour between the two sexes. The 

 male is bluish black, with light blue spots on the belly, while 

 the thighs and the inner sides of the legs are beautifully red. 

 *rhe female is deep black, with a light green spot at the base and 

 in front of the limbs ; the rest is coloured like the male. 



Cardioglossa gracilis, quite recently discovered at the Gaboon, 

 has likewise to be added to the Dendrobatinae, on account of the 

 absence of teeth. It is a small, slender, arboreal frog, bearing 

 an unmistakable resemblance to the other genera by its general 

 appearance and conspicuous, contrasting coloration of black and 

 white.
