MEGALOPHRYS MONTANA. 413 



prolono;ecl. One of them lias broadly webbed hind toes, and is a " powerful leaper ;" the other has them 

 but slightly webbed, being a " crawler " and tree-frog ; nevertheless they are referred to the same genus ! 

 It is not at all improbable that the former is a true Rana !

Head very broad and depressed, with a sharp canthus rostralis ; body rather broad and 

 short. The upper eyelid is produced into a triangular flap, which is longer in the male than 

 in the female. The tip of the snout terminates in a similar but shorter appendage in the 

 male, whilst it is rounded and without appendage in the female. The cleft of the mouth is 

 wide, much broader than long. The vomerine teeth are minute, and sometimes lost ; they 

 are implanted on two short linear prominences, which are on the same level with the 

 choanse, and run backwards in a straight line. The choanse are somewhat larger than the 

 orifices of the eustachian tubes. A bony ridge runs backwards from the eye to above the 

 tympanum, which is covered by the skin, but becomes visible, after removal of the latter, as 

 an oblong and rather small slit. Pupil vertically rhomboidal. Skin of the upper parts 

 almost smooth, with a few folds and conical tubercles : one fold divides the occiput from the 

 nape, and another runs along each side of the back ; there is sometimes another transverse 

 fold between the longitudinal ones on the middle of the back. Of the tubercles, one above 

 each shoulder-blade, outside of the longitudinal folds, is the most constant : the males have 

 almost always a black conical tubercle with a white tip in the centre of the sacral vertebra. 

 Nearly all the other tubercles are on the side of the body and on the belly, but more nume- 

 rous and more distinct in females than in males. In old individuals the skin has groAvn to 

 the bones of the skull, and is thickened and hardened in the humeral region. 



Limbs of moderate length, the length of the body being equal to the distance of the vent 

 from the base of the inner toe. Toes distinctly but shortly webbed at the base. Soles of 

 the feet without tubercles. 



Darker or lighter greyish brown above, with the tubercle on the shoulder black ; male 

 with another black tubercle in the centre of the sacrum ; a subtriangular blackish-brown 

 spot edged with white on each side of the upper jaw, including the orbit. A large round 

 dark-brown spot on the elbows, knees, and heels, and at the vent. Lower parts densely 

 marbled with brown ; male with a white blotch on each side of the chest ; palms and soles 

 dark brown. Iris rich golden brown, minutely reticulated with black. 



A female specimen, said to be from Ceylon, If inch long, differs slightly from those of the 

 Archipelago in having the snout a little more pointed, although not produced, and in the
