' It is possible that this mny be the true 0. retula of Wagler (Penelope vetula Wagl., Isis, 1830, 1112), 

 which seems to agree exactly in color with 0. mnccnIH ; but the size is much smaller, the length being given 

 as IS inches, the tail 9.70. The locality is given as simply " Mexico," ami it may bo thut a fourth local race, to 

 which Waglor's name is strictly applicable, may exist in some portion of Mexico specimens from which have 

 not come under my observation.
