the Atlantic Cossonides. 



36: 



As a slight aid to the eye, in judging of their /lab'tials, I have 

 thought it worth vvliile to give the following geographical tabula- 

 tion of these Cossonides, which will show at a glance to what 

 island-groups they respectively belong ; and it is curious to re- 

 mark, that the species are so topographically restricted that ap- 

 parently onli/ one out of the whole forty (namely, the Mesoxenus 

 Momzianus), has its range extended beyond a single cluster ; 

 whilst two extensive genera (not to mention smaller ones) — . 

 namely, Caulotrupis and Microxylohius, are, in like manner, thus 

 limited geographically.
