76 HERPETOLOGICAL NOTES. 



ation in several genera. Lechriodus is a Pelobatid of doubt- 

 ful affinities (as regards other members of its family) and 

 with Asterophrys exists well separated from other genera 

 of the Pelobatidae. Thus its affinity to the AustraUan 

 Cystignathids and its propinquity of habitat point to a 

 striking conclusion. A true Cystignathid, too, Phanerotis 

 {=Ranaster), is now known from New Guinea.

Size small. Habit very slender. Head almost as 

 long as broad, the measurement taken at a Une drawn 

 between the hinder margins of the tympana. Eye large, 

 its diameter a trifle longer than that of the snout ; the 

 latter rounded, sHghtly prominent ; nostrils much nearer 

 the tip of the snout than the eye ; canthus rostrahs very 

 rounded ; loreal region not concave. Inter-orbital region 

 a little broader than the upper ej-e-hd. Tympanum very 

 distinct, perfectlj^ round ; separated from the eye by a 

 distance less than its diameter, which is about one-half 

 that of the eye. Tongue oval or sub-circular, entire, 

 .^jometimes ■with a median longitudinal groove or three 

 small dimples ; free a little behind and on the sides. 

 Vomerine teeth always present ; in two small oblique separa- 

 ted groups, their front edges on a level with the hinder edges 

 of the widely distant choanse. Skin smooth ; a mere 

 indication of a fold above the tympanum across the chest 

 and along the inner edge of the tarsus ; under-surfaces 

 of the thighs and belly granular. Fingers with a distinct 

 web, the deepest part of the concavity of the web between 

 the third and fourth on a level with the proximal sub- 

 articular tubercle ; others less than one-third webbed ; 

 fringed to the discs ; discs as large as the tympanum ; 

 sub-articular tubercles distinct ; a number of swollen
