102 THE HERPETOLOGY OF CUBA. 
rough and looked unfinished. Those with the rims each contained a Bufo empusus. The 
tube-like burrow was perfectly cylindrical and from seven to ten inches deep. The toad 
which always looked larger than the diameter of the burrow, was to be found in a small 
chamber at the bottom, its curious hornlike, shelly, hea forming an operculum which closed 
the burrow accurately. To accomplish this closing most advantageously, the toad was 
sometimes found resting on its side or back. The small individuals were frequently observed 
near the surface, their little heads just fillmg the mouth of the tubes. Only one or two 
adults were observed near the surface. The other burrows spoken of were inhabited by 
Tarantulas, which were excessively common. 
Gundlach says, and he is confirmed by what the country folk told me, that these toads 
come forth to sing in unison on warm nights after a rain. There is no apparent rule to guide 
their appearance and they are not heard during many apparently favorable nights. The 
people told me that they had never met them outside their burrows, probably because they 
had not visited this particular field by night. From what I have heard, I am sure this species 
always occurs in these colonies in areas where the soil is suitable for making their burrows.”
