This curious Frog is easily distinguished from the L. Tasmaniensis 

 by the large, swollen, oval gland on the calf of each leg, as well as 

 by the darker coloring of the back and the dark chocolate marbling 

 of the underside, the broader and thicker head, and the smaller 

 number of tubercles on the underside of the ankle and wrist joints ;
