D. concinna is known from the West Indies and the Andes from

 Underwood. Frequently material was divided between us at the time of col- 

 lection and dried separately. Dr. Underwood giving his numbers to the series

 for the U. S. National Aluseum. For convenience of reference I kept a 

 record of such of Dr. Underwood's numbers as were thus exactly equivalent 

 to my own. Except for a few scattering specimens Mr. Christensen has seen 

 only my series ; but as an aid to those who may have received Dr. Underwood's 

 duplicates, his equivalent numbers are here cited in parentheses by Mr. Chris- 

 tensen, these being copied from my labels.- — William R. M.\xon.
