Head rather short ; body yellowish brown, with small dusky 

 rhomboidal spots and lines, sometimes arranged in the form of a

2. HYLARANA. 



Vomerine teeth. Skin smooth, generally with two glandular

* Tills genus might belong to the family of Hylidse. Bibron and also Baird 

 describe the diapophyses of tlie sacral vertebra as not dilated ; but I ask natiu-alists 

 having the opportunity of examining fresh specimens, to direct tlieii* attention to 

 this subject. The relation to Pseudacris nigrita is Tery great, which species 

 also exliibits only slightly dilated processes.
