There are two forms of this subspecies, which htive received the 

 names of viride.scens and niiniatus respectively. These havinj"' been 

 shown to be st aj^cs of one <ind the same Jininial, they are not dislin- 

 l^nishi'd otlierwise than as .seasonal forms, which may be by reason of 

 !iu' i'livironment lendered iternninent for a longer or shorter time. I 

 l^ive, however, the ciiaracters that distinj^uish them. 



Cr.ini.il carin.i' more iirominent, and longer; tongue freer laterally; skin rough; 



cheek-pits inoro freiiuently wanting; color red form ininiiiliin. 



Cranial carina' le.s.s prominent, especially at the ends; tongue less fiee ; skin smooth; 



check [>it.s rarely wanting ; ground color olivaceous form ririihxiriin- 



Tlie form niiniatus never has a caudal fin-membraiie, while it is }>eu- 

 craliy present in the form Viride.scens; but this is a seasonal character. 

 Tiie characiters ab()vc mentioned are not always combined as described, 

 atid one (ir another may be wanting while the others are present.
