* There cannot be the least doubt that these specimens from Guayaquil belong 

 to the same species ; the male is rather smaller, and exliibits all the warts covered 

 with spmes, whilst in the female only some of the warts exhibit a horny surface. 

 Other male specimens in the Collection show the same peculiarity. In this spe- 

 cies the size of the tympaniun is subject to some variation in specimens from 

 the same locality and with the same external characters.
