For color descriptions the senior author has used the color names 

 in Robert Ridgway's A Nomenclature of Colors for Naturalists . . ., 

 1886 edition, although the value of such precise naming for old and 

 faded material is often questionable. The junior author uses more 

 popular color names. 



The critical measurements are the head-and-body length; head 

 length, from posterior corner of tympanum; head width, between 

 typani; femur, one-half the distance between distal ends of femur 

 when at right angles to body; tibia; foot, from distal base of inner 

 metatarsal tubercle to tip of fourth toe; and hand, from base of 

 thumb to tip of third ringer. The senior author records measurements 

 to the nearest half millimeter; the junior author measures in tenths 

 of millimeters. The senior author omits a diagnosis before discussing 

 previously described forms, considering most diagnostic characters 

 to have appeared in the key to the genus; the junior author presents 

 a diagnosis before each description. 



Our pleasure in acknowledging the help we have received while 

 working on this project is tempered only by the fear that we have 

 failed to thank some of the many persons who have been so kind to us.
