 Taboga and Panama ; 0. B. A. ! 

 We collected 32 specimens, 12 of which were taken alive. 

 Many of them are covered with prominent spiral linear ridges, 

 which are wanting on others. But the number of specimens 

 with intermediate characters is so large as to show that the dis- 

 tinction is not of specific value.
