Palatine teeth in two slightly arched series, extending externally 

 beyond choanae, separated from parasphenoid teeth ; latter in two 

 patches close together anteriorly, diverging posteriorly. Head 

 moderate, longer than broad ; snout truncate, with distinct canthus 

 rostralis and very oblique loreal regions ; a more or less marked 

 swelling below each nostril, remnant of the cirrhus apparently 

 common to the young of all the species of this genus ; in the young 

 the nostril is enormously large, as in the genus Thorius ; eye rather 

 large, prominent. Body short for the genus, measuring only about 

 twice and a half the distance from tip of snout to gular fold. Limbs 

 moderate, meeting when laid against the body ; fingers and toes 

 short, the tips very obtuse, almost truncate, half webbed ; no carpal 

 or tarsal tubercles. Tail cylindrical, shorter than head and body.
