creatures they may exist in a locality comparatively well explored 

 zoologically without their presence being suspected until they are 

 found by the merest accident, renders it quite impossible to draw any 

 conclusions regarding the exact relationships and dispersal of these 

 forms. 



For the sake of comparison, descriptions of the genera Cacopus and 

 Kaloula are added hereto, as well as Boulenger's original description of 

 Kaloula verrucosa : — 



Cacopus Gthr. 



Pupil erect. Tongue oval, entire and free behind. Choanae very 

 large, with a dermal movable flap, which can close the nostril; two 

 small bony prominences close together, between and on a level with the 

 hinder edge of the choanae ; a small papilla on the hind margin of each 

 choana; a narrow r denticulated dermal ridge across the sphenoidal 

 region ; another, very broad, in the front of the oesophagus. Tympanum 

 hidden or very indistinct. Fingers free; toes webbed at the base, the 

 tips not dilated. Outer metatarsals united. Precoracoids none; 

 sternum a large cartilaginous plate. Diapophyses of sacral vertebra 

 rather strongly dilated. Terminal phalanges simple. 



India. (Boulenger, Cat, Batr. Sal, 1882, p. 174.) 



Kaloula Gray. 



Pupil erect. Tongue oblong, entire and free behind. Vomerine 

 teeth none. Palatine bone forming an acute, sometimes toothed ridge 

 across the palate. Two cutaneous, more or less distinctly denticulated 

 ridges across the palate, in front of the oesophagus. Tympanum hid- 

 den. Fingers free, toes more or less w T ebbed (exceptionally free), the 

 tips more or less dilated. Outer metatarsals united. No precoracoids; 

 no omosternum ; sternum cartilaginous. Diapophyses of sacral ver- 

 tebra moderately dilated. Terminal phalanges triangular or T-shaped. 



East Indies. (Boulenger, I, c, p. 167.) 



Kaloula verrucosa Blgr. 



Snout rounded, not prominent, as long as the eye; interorbital 

 space as broad as the upper eyelid. Fingers slender, with slightly 

 swollen tips, first a little shorter than second; toes moderate, nearly 

 half-webbed, the tips blunt, not swollen, fifth considerably shorter than 

 third; subarticular tubercles well developed; metatarsal tubercles 

 two, oval, compressed, the inner very large. The tibiotarsal articu- 

 lation reaches the shoulder or between the shoulder and the eye 

 Upper parts with large smooth warts ; a fold from the eye to the shoul- 

 der. Dark grayish brown above, uniform or with six longitudinal rows 

 of small darker spots ; lower parts uniform dirty white.
