Synonymy. — The name H. laevicaudatus lias been placed by 

 previous authors in the synonymy of hudsonius, and this action is 

 followed here. There is nothing in the original description to in- 

 dicate whether it refers to the present subspecies or to piinctulatus, 

 and the given locality, "North America", does not help to decide the 

 question. In either case it does not affect the nomenclature, since 

 it is a later name than either hudsonius or punctulatus. The length 

 of the snout shown on the figure of laevicaudatus is more nearly like 

 that of hudsonius.
