NotTE.—Some of the species enumerated in the following list are now 
possessed by the National Museum, but other specimens are needed,

imperfect examples. The species in the collection are indicated by a 
star (*), and the numbers correspond with those of the Check-List. 
The names for which authorities are given are most earnestly desired,
