410 BATRACHIA. 



Greyish olive, with large dark spots and bars on the back and limbs ; a triangular trans- 

 verse spot between the eyes, with the point directed backwards, is always present. A white 

 vertebral line is rarely wanting. Five broad short bands radiate from the orbit, forming two 

 spots below the eye ; the hinder band passes the tympanum. Uniform white below. 



This is a small species, only If inch long, the hind limb measuring 2^ inches. It is 

 common near Ningpo and Hongkong, and is also found in Loochoo. We have received speci- 

 mens from the Himalayas ( Jamu), from Siam, and from Madras ; the latter have the hind 

 limbs comparatively a little longer.

Hoplobatrachus, Peters, Monatsber. Berl. Acad. 1863, p. 449. 



Fingers quite free ; toes completely webbed. Vomerine teeth in two 

 oblique series ; tongue deeply notched behind. Openings of the eustachian 

 tubes small. Metatarsus with a flat, sharp-edged prominence. 



This genus has been established for a single species from Ceylon, which I have never seen. 



HOPLOBATKACHUS CEYLANICUS. 



Hoplobatrachus ceylanicus, Peters, I. c. 



In habit similar to Rana esculenta. Head as long as broad ; snout rounded, one-fourth 

 longer than the diameter of the eye ; canthus rostralis obtuse ; loreal region very high, con- 

 cave along its middle. Tympanum rather indistinct, half as large as the eye. Cleft of the 

 mouth comparatively narrow, the inner angle of the mouth being before the hind margin of 

 the orbit, although the outer is situated below the middle of the tympanum. Choanee very 

 large ; the vomerine teeth form two oblique series, convergent behind ; they are placed on 

 two bony ridges commencing from the anterior inner angle of the choanse. Male with a 

 vocal sac, opening by a pair of slits, which are situated a little before the inner angle of the 

 mouth. Skin of the back with longitudinal folds and tubercles ; a transverse fold from the 

 hind part of one orbit to the other ; another fold descends from the orbit above the tym- 

 panum to the upper arm. Hind limb considerably longer than the body ; toes webbed to 

 the tips, the mterdigital membranes being rather deeply emarginate. A fold of the skin 

 runs along the inner side of the tarsus and extends to the base of the metatarsal tubercle ; 

 there is no second tubercle, but a membranaceous fringe runs along the outer side of the 

 tifth toe. 



Dark green above, with blackish markings: viz., five cross bars on each upper lip, corre- 

 sponding ones on the lower, and a spot at the angle of the mouth ; a black streak along the
