Types. — The types of all Greene's species seem to have 

 been lost. At least a part of them were alcoholic specimens 

 and they were examined at one time by Mr. Cresson. When 

 asked about them, Mr. Cresson told me that he did not know 

 where they were unless they were in Boston. Prof. Johnson 

 has been unable to find them for me in the collection of the 

 Boston Society of Natural History and Mr. Henshaw has 

 been unable to locate them in the collection of the Museum
