* This genus might belong to the family of ITylidne. Bibron and also Baird 

 describe the (liiipo]iliysc8 of the sacral vertebra as not dilated ; but I ask naturalists 

 having the opportunity of examining y)('.s/; specimens, to direct theu- attention to 

 this subject. The relation to Pseudacris nigrita is very gi'eat, which species 

 also exliibits only slightly dilated processes.
