Batrachians from Australia. 27 



Limnodtjnastes affinis. 



This species also is very closely allied to L. tasmaniensis and 

 L. Krefftii, but is distinguished by the following characters : — 



No large gland on the hinder extremities; skin of the 

 back smooth; carpus and metatarsus each with two tubercles. 

 Broiunish-olive, with a few brown blotches on the back ; a whitish 

 vertebral line is scarcely indicated; a brown streak along the 

 canthus rostralis, continued behind the eye towards the shoulder, 

 its hinder portion having a whitish inferior edge ; lower parts 

 uniform whitish. 



A single female specimen, from the Clarence River, is in the 

 collection. 



Length of the body 15 lines, of the fore leg 8 lines, of the 

 hind leg 21 lines, of the fourth toe 7 lines. 



Platyplectrum. 



(Fam. Cystignathidae.) 



Fingers and toes tapering, free, the latter with a very narrow 

 fringe of a web ; maxillary teeth ; vomerine teeth in a straight 

 transverse line. The internal openings of the nostrils and of the 

 eustachian tubes very small ; tympanum covered by the skin. 

 Tongue circular. No parotids. The transverse process of the 

 sacral vertebra not dilated. Metatarsus with a flat sharp-edged 

 spur (as in Spharotheca). 



This genus is distinct from Limnodynastes, which has only 

 one or two small tubercles on the metatarsus. 



Platyplectrum marmoratum. PI. IV. fig. A.

 rostralis very obtuse; nostril on the canthus rostralis, in the 

 middle between the eye and end of the snout ; upper parts with 

 very small smooth tubercles ; legs short. Olive, the upper parts 

 marbled with brown ; a narrow light cross band between the 

 orbits, edged with brown in front and behind ; the lower parts 

 uniform whitish. 



Length of the body 18 lines, of the fore leg 9 lines, of the 

 hind leg 24< lines, of the fourth toe 7 lines, of the fifth 5 lines. 



A single specimen, from the Clarence River, is in the collec- 

 tion ; it is a male, with a wide slit on each side of the tongue 

 for the vocal sac.
