102 THE HERPETOLOGY OF CUBA. 



rougli and looked unfinished. Those with the rims each contained a Bvfo cmpvsiis. 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, head forming an operculum which closed 

 the barrow acciu'ately. 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 filling 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 fa^•orable nights. The 

 people told me that they had never met them outside their burrows, probable.' because they 

 had not visited this particular field by night. From what I have heard, I am sure this species 

 always occiu's in these colonies in areas where the soil is suitable for making their burrows."
